Setting `"narrowed-after-fetch"` keeps the qualifier regardless of `firstPage`/`hasNext`, and refuses to honour a `total` even if one is present — both enforced inside `listOutcome`, not left to the caller. `orders-list.tsx` and `@otta-sh/plugin`'s Block Kit `listResult` (and its one caller, Coupons) state `"service-filtered"` explicitly; no behaviour change for either, since neither narrows a fetched page. -The Pricing & inventory list sets `"narrowed-after-fetch"` from whether the low-stock narrowing **actually applied to the page being rendered**, not from whether the operator checked the box: the plugin can leave a request unnarrowed (`stock.filterUnavailable`, when the low-stock threshold can't be read) while still returning every product and the service's own exact `total`, and the count now reads "products" — with that real total — on exactly that page, never "low-stock products" beside a total that describes a different set of rows. +The Pricing & inventory list sets `"narrowed-after-fetch"` from whether the low-stock narrowing **actually applied to the page being rendered**, not from whether the operator checked the box: the plugin can leave a request unnarrowed (`stock.filterUnavailable`, when the low-stock threshold can't be read) while still returning every product and the read's own exact `total`, and the count now reads "products" — with that real total — on exactly that page, never "low-stock products" beside a total that describes a different set of rows. diff --git a/.changeset/merchant-restock.md b/.changeset/merchant-restock.md index 56a76eec..68fee4ae 100644 --- a/.changeset/merchant-restock.md +++ b/.changeset/merchant-restock.md @@ -1,7 +1,5 @@ --- "@otta-sh/domain": minor -"@otta-sh/store-postgres": minor -"@otta-sh/service": minor "@otta-sh/plugin": minor --- @@ -24,16 +22,6 @@ reservation-scoped, so a merchant had no safe path to change a live sku's raw on is a typed `StockMovementMismatchError`.

Enumerating +the record was, and remains, the branch that fires in production. + +What changed is that the lookup no longer depends on that staying true. It sniffs +the container at runtime (`Headers` is identified by its `.get`, which is already +case-insensitive) and falls back to the case-insensitive enumeration otherwise, +so a future dispatch path that handed over a genuine `Request` would be read +correctly rather than silently seeing no headers at all. No public export +changed, and the gate's semantics are untouched: an unset token still passes +through, a present-but-wrong token is still refused in constant time, and the +Stripe HMAC is still unconditional. diff --git a/.dependency-cruiser.cjs b/.dependency-cruiser.cjs index c7b437a7..7f73b971 100644 --- a/.dependency-cruiser.cjs +++ b/.dependency-cruiser.cjs @@ -6,6 +6,8 @@ module.exports = { forbidden: [ { name: "domain-is-io-free", + // TODO(#291): this rule still names the deleted `service` package, in the + // comment below and in the last clause of `to.path`.

First, @otta-sh/domain, which was named in all three " + + "@otta-sh clauses. The boundary was never `the plugin must not know the " + + "domain`; it was `the plugin must not acquire IO`, and banning the domain " + + "was a cheap PROXY for that — cheap because the domain is the package " + + "most likely to grow an adapter import. The proxy is no longer needed and " + + "was blocking the thing ADR-0002 designed for: the domain has zero " + + "runtime dependencies and zero node: imports, and `domain-is-io-free` " + + "above enforces exactly that, on every commit, as this rule's premise. " + + "Importing the domain therefore cannot put IO inside the isolate; " + + "importing an ADAPTER can, which is why every adapter except one stays " + + "banned. Second, that one exception: `store-[^/]+` in the packages clause " + + "became `(?!store-emdash/)store-[^/]+`, so packages/store-emdash is " + + "admitted while any other store-* — including any added later — is banned " + + "by default rather than by anyone remembering to add it — and the same list " + + "is mirrored into the two SPECIFIER clauses, not only the packages " + + "clause, because pnpm's strict isolation leaves an UNDECLARED import as " + + "a bare specifier that never resolves to a packages/ path: naming only " + + "admin-react there meant an undeclared @otta-sh/store-* " + + "or payments-* import tripped nothing at all, which is the same class of " + + "silent miss as the `^node:`-only builtin clause. store-emdash is " + + "admissible because it carries no IO of its own: it is written against a " + + "structural StorageAccess port whose implementation arrives injected, and " + + "three store-emdash-* rules below hold it to the same perimeter as this " + + "one, type-only imports included.\n\n" + + "THIRD NARROWING (work order 02, INC-C1b): `payments-[^/]+` became " + + "`(?!payments-(stripe|x402)(/|$))payments-[^/]+`, in all three clauses, " + + "so @otta-sh/payments-stripe and @otta-sh/payments-x402 are admitted and " + + "every other payments-* package stays banned by default. The reason is " + + "the same shape as store-emdash's, and it is a statement about those two " + + "packages rather than about payment adapters generally: with the service " + + "folded in there is no second deployable to verify a Stripe webhook in, " + + "and an UNAUTHENTICATED webhook only ever reaches a plugin route " + + "registered `public: true` — so the HMAC verification has to happen " + + "inside the isolate.

Per +[ADR-0019](./adr/0019-commerce-aggregates-are-one-document-each.md), these sweepers are not +an optimization — a coupling that spans two aggregates is made idempotently completable +rather than transactional, so **a missing sweeper is a correctness bug**. The site's cron +may be relaxed (e.g. `*/5 * * * *`) if cron noise ever matters more than publish latency, +but relaxing it past the task's own `*/15` delays every sweep. + +**Scaling.** Commerce truth is one document per aggregate in the site's D1 database, written +by compare-and-set; every command carries an idempotency key the store enforces once-only, +and the sweeps are idempotent, so concurrent isolates racing the same sweep never +double-release or double-send.

So owning commerce truth in-process needs no new grant and widens no declared +permission. + +The second was our own lint rule. `plugin-is-sandbox-clean` forbade the plugin from importing +`@otta-sh/domain` at all. That ban was never a statement about knowledge; it was a **proxy for +"the plugin must not acquire IO"**, and the domain was a cheap thing to name because it is the +package most likely to grow an adapter import by accident. The proxy is now costing more than +it buys: it forbids precisely the composition ADR-0002 designed for, while the property it was +standing in for is enforced directly and on every commit by `domain-is-io-free` — the domain +has zero runtime dependencies and no `node:` imports anywhere in its sources. + +There is also a host-version fact. The document store's **conditional-write primitives** — +guarded update, versioned read, revision-based compare-and-set, revision-based delete — are +what make a single-document write safe under concurrent writers, and therefore what make +commerce truth on `ctx.storage` correct rather than hopeful. They are not available in a +released host: one is merged upstream but **unreleased**, and the rest are an **open upstream +change**. Until a release carries them, +the repo binds a **locally built, vendored build of the host** that does. + +## Decision + +1. **The EmDash plugin may own commerce truth in-process, on `ctx.storage`.** The domain's + use-cases may be constructed inside the plugin and bound to the store the host injects.

It is admitted into the plugin's perimeter on the same reasoning as the + domain — it carries no IO of its own, because its storage implementation arrives injected. +4. **The capability posture does not change.** The descriptor's capabilities stay exactly the + manifest's two. Nothing here adds a capability string, because there is none to add: + `ctx.storage` and `ctx.cron` are ungated. + +### What ADR-0006 keeps + +Decision 2's other prohibitions all stand: no React admin components in the standard-format +plugin, no `page:fragments`, no `options`-configured native format, nothing that works only in +trusted mode. + +**"Zero EmDash dependency" also stands — for the plugin package.** It has no dependency on the +host, in either manifest section, and none of its sources import host code. What makes that +survivable is that `ctx` is *injected*: owning commerce truth needs the storage object, not the +host's implementation of it. + +For `@otta-sh/store-emdash` the same claim **narrows, deliberately, to "zero EmDash *runtime* +dependency"**. The structural port is written in terms of the host's own storage types via +`import type`, so the adapter names the host's types and never executes the host's code. A type +import emits nothing, so it cannot put host behaviour inside the isolate; a runtime import of +the same module would, and fails the build. This allowance is not an oversight to be tidied +later: hand-mirroring those types would buy no safety and guarantee drift. It is held to by a +dedicated lint rule rather than by convention. + +### ADR-0006 Decision 1 is reaffirmed — with an honest statement of what it proves + +The workerd sandbox suites remain the contract gate. A change that only works with the plugin +registered trusted is still broken and must not merge. Commerce truth moving in-process makes +that gate *more* important, not less, because the storage code paths it will have to exercise +are where the money lives. + +It is worth being exact about the gate's reach, because it is easy to overclaim: + +- **Today the sandbox suites exercise the injected HTTP and key-value surfaces only.** The + harness builds a plugin context with those two members; there is no `storage` on it, and + existing suites assert its absence. So as of this record, no sandbox suite touches a + storage code path — because there are none in the plugin yet. +- **This record therefore carries an obligation, not a claim.** The storage-backed sandbox + suites **will inject a real storage repository** into the plugin's context, so that the + plugin's storage code paths are exercised **under real workerd against the real storage + implementation** — not a fake, not a reimplementation. They land with the increment that + puts commerce truth on `ctx.storage`, and the gate is not satisfied until they do. +- **Injecting the repository is not the same as going through the host's sandbox bridge**, and + the difference must not be blurred. The bridge is real, and it does wire all four + conditional-write operations; **no Otta tier exercises it**, and none is planned to, because + first-party deployments register the plugin trusted and nothing deployed depends on it. +- **The D1 tier is what observes the real host code**, and its reach is also worth stating + exactly: it constructs the host's **real storage repository** over the host's **real + migrations** and the host's **real D1 dialect**, built the way a deployed site builds it, and + runs against the local simulator. It does **not** load the plugin, its context, or the + bridge. So it answers "do the primitives behave on this dialect" rather than "does the host + hand them to a sandboxed plugin correctly". + +### The vendored host build, and why ADR-0014 Decision 5 is amended + +ADR-0014 Decision 5 required the dependency floor to stay stock and pinned exact, with no fork, +no fork build, no patched dependencies, no overrides and no vendored copy. For the duration +described here, it does not. + +**No published host release carries the conditional-write primitives.** Without them there is +no correct way to hold commerce truth in a document store — a read-then-write cannot be made +safe under concurrent writers — so the alternatives were to **wait for a release**, or to ship +a reference implementation of the primitives that would immediately drift from the real ones. +Waiting was rejected: the primitives exist as upstream code today, and the decision is not +blocked on anyone's release schedule. + +So the repo binds a **locally built, vendored build of the host** carrying them.

There is no transaction, no multi-row batch, no raw SQL and +no host DB handle. Cross-document atomicity is therefore **not available and cannot be asked for** — +a law of the primitive set, not a gap awaiting an upstream change. + +The implementation being replaced is a set of Kysely stores whose correctness rests on exactly the two +things the document store lacks: multi-statement transactions and row locks. Every money-path +invariant is currently a SQL predicate — `WHERE on_hand >= qty`, a `pending` claim flip, a refund +ceiling computed under a portable row lock, two inventory rows locked in sorted order. **Those stores +are deleted at the service-removal increment**, and their semantics would go with them. Section 7 is +where they survive. + +The forcing observation is narrow and worth stating alone: + +> **An inventory decrement is not idempotent unless the row records who applied it.** + +A reservation held "pending" somewhere else cannot distinguish crash-before-decrement from +crash-after. Recording the applying reservation *inside* the inventory row is the only fix — which is +also why the queued "single-statement conditional `UPDATE`" decision does not survive: one guarded +statement can decrement, but it cannot simultaneously record the hold that makes the decrement +replayable. Once the holds map is inside the inventory document, the same discipline resolves orders, +refunds, carts and coupons for free. + +## Decision + +### 1. The rule + +> **An invariant that spans two facts lives in ONE storage document.

Both are +corrected. **Two sites exist and two is the whole set**: coupon redemption's global counter bump (§3, R1) +and the coupon **release floor** guarded on `usesCount > 0` (§7.15) — both **guarding** the same field of +the same document, one incrementing under a cap, one decrementing above a floor. (The bump's write also +stamps a best-effort witness field alongside the delta. That is deliberately *not* part of its guard, and +it is why the tier is named for what a write guards rather than for what it touches.) The third planned +site, the **email-outbox lease** (§3, R2), was built as a **`compareAndSet`** instead and belongs in the +tier below, for the reason that decides all of these: holding a lease means the writer must know *which* +document state it is extending — a lapsed peer's lease is a takeover, an absent order is a bug — which is +exactly the distinction `updateIf` refuses to report, since it conflates a failed guard with an absent +row. Hence the tier's new name. The rule the recount leaves behind is sharper than a number: **`updateIf` +is for a write whose entire invariant is one comparison on one field and whose caller needs no idea why +it failed.** Everything else — including every lease — is `compareAndSet`. + +Both surviving sites take their refusal **decision from a prior read**, never from `applied: false`, for +that same reason. + +**Reserve is a `compareAndSet` read-modify-write, permanently.** A guarded single statement cannot +carry it: the hold must be recorded in the same write as the decrement, and the hold lives at a nested +path. A nested-path guarded update would make reserve lock-free again, but that primitive is not being +sought, so the interim answer is the permanent one — bounded jittered retry, a documented ceiling, a +typed retryable error, and measurement. + +### 2. Inventory, as built + +This is the one part of the model that **exists**. The decisions and the numbers are recorded here; +the **living detail** — the per-method choreography, the eight fault-injected crash seams and the +per-shape measurements — lives in `packages/store-emdash/README.md` and is not restated here. + +| Collection | Doc id | Holds | +|---|---|---| +| `inventory` | sku | `onHand`, the live `holds` map, the bounded applied-movement ring | +| `reservation_keys` | reserve idempotency key | the durable claim, then the terminal `ReserveResult` | +| `reservation_index` | reservation id | `{ sku, idempotencyKey }` plus the reservation's terminal state | +| `inventory_movements` | `stock:` / `adjust:` | the per-key intent, then its recorded answer | + +**Reserve is a two-step, not one atom.** The plan that preceded this record described it as a single +atom; it is not, and cannot be. The sequence as built, including its two early `OUT_OF_STOCK` exits — +which differ, and the difference is load-bearing: + +1. Read `reservation_keys/{key}`. A **terminal** document returns the recorded result; a **claimed** + one is completed (this is the heal path, callable by anyone). +2. Read `inventory/{sku}`. **An absent inventory document returns `OUT_OF_STOCK` and claims nothing** + — an unseeded sku is outside the idempotency scope and the key stays usable once the sku exists. +3. If `onHand < qty`, write the key document **straight to terminal** with `reservationId: null` and + return `OUT_OF_STOCK`. Unlike step 2 this **does** write a document — the key is consumed — but it + is decided **before any reservation id is minted**, so a refused reserve leaves no id and no index + document behind, only the terminal key document that makes the replay stable. (The `null` is a field + of the stored key document; the port's failure result has no `reservationId` field at all.) +4. Otherwise **claim** `reservation_keys/{key}` create-if-absent with a freshly minted reservation id, + then complete: write `reservation_index/{reservationId}` (**before** the hold, its create-if-absent + result asserted — a colliding id is a loud `ReservationIdCollisionError`), then **one + `compareAndSet` on `inventory/{sku}`** in which the `onHand >= qty` guard, the new count and the + hold record commit together, then promote the key document to its terminal `ReserveResult`. + +Steps 1–4 sit inside a key-resolution loop bounded at **`ROUNDS = 2`**, because a create-if-absent +claim can only fail because a document now exists and the next round reads it. That loop is distinct +from — and outside — the `CAS_MAX_ATTEMPTS`-bounded compare-and-set loop within step 4. Exhausting it is +treated as contention beyond what the loop can resolve and throws the same typed retryable error as an +exhausted retry budget, never a bare failure. + +**Window one: claim written, compare-and-set not yet run.** Healed, not tolerated: any replayer finds +the `claimed` document and completes it deterministically, reusing the **recorded** reservation id +rather than minting a second one. A sweeper reaps claims nothing replays. The window cannot be removed +by any single-document primitive, because the claim and the units live in different documents. + +**The SQL adapter had no second crash window, and this record does not claim one.** Its `pending → held` +flip and its `on_hand - qty` decrement ran in the **same transaction with no commit boundary between +them** (§7.2), so there was nothing to crash between. What the embedded aggregate buys is therefore not a +window removed but a **simpler shape**: one write instead of two statements, no `pending` state to +observe or reap, and — because the hold in the document *is* the record of application — **no polling +loser**. The SQL adapter's race loser had to poll the reservation row up to 200 times and could time out +into an untyped error; the document model's loser completes the claim and reads its answer. + +**Window two: inside the compare-and-set step, mitigated rather than removed.** Between reading the +aggregate and committing, a peer completing the SAME claim can create the hold, commit it and prune it. +The waking caller would see no hold under its key and a low `onHand` with nothing to show for it, and a +committed prune returns no units — so a second hold there would be permanent, silent stock loss. The +mitigation is in the step: **whenever `holds[key]` is absent the key document is re-read**, and a +terminal one ends the attempt with the recorded answer and no write. The residual is **one storage +round trip**, and closing it needs cross-document atomicity. + +**Why `reservation_index` is not optional.** Six port methods — `commit`, `release`, `adjust`, +`releaseAdopted`, `adoptMany`, `commitMany` — take reservation ids with **no sku**, and a hold embedded +per SKU cannot be found from an id alone. Because the index is written before the hold, an id absent +from it is **provably** unknown: that is what lets `commitMany` throw `ReservationNotFoundError` for a +truly unknown id while `adoptMany` folds one into `lost`. It also carries the **terminal** state, +because pruning a hold would otherwise erase the difference between "never existed" and "existed and +was released". + +#### The replay ordering rule — this is atomicity, not bookkeeping + +> **The terminal answer is written to the key document BEFORE the hold is pruned from the inventory +> document.** The prune is the second, idempotent step, and it is swept. A hold may therefore be +> observed both live and terminal, and the replay path reads the key document first, treating a live +> hold as authoritative only in its absence. + +Prune first, crash, and a replay finds neither a terminal answer nor a live hold, concludes the key is +fresh, and **decrements a second time** — a once-only violation on the money path. The rule is pinned +from the forbidden side: the terminal write is parked, and while parked the hold must still be live and +the units still off the shelf. A store that pruned first would pass every replay case and fail that one. + +#### Movements: bounded ledgers, a witness ring, and one accepted residual + +`adjust`, `restock` and `removeStock` keep their once-only record in `inventory_movements` — one +document per key, carrying the full intent and then `applied` with the recorded result. **There is no +`state` field; an absent `applied` IS the unfinished marker.** The hot aggregate keeps only +`appliedMovements`, a ring of the last **256** applied keys with their answers, plus `lastMovementKey` +on a hold — written **only by `adjust`**, and pruned with the hold. + +**The accepted bounded residual, and the sweeper contract that closes it.** A replay delayed past 256 +later movements on the same sku loses its witness: a stock movement would apply a second time, and an +`adjust` whose hold has also been pruned throws `ReservationNotHeldError` rather than invent an answer. +Closing it needs a second atomic document. It is therefore an accepted **bounded** residual with a +contract the sweeper must satisfy: + +> A movement claim document in `inventory_movements` whose `applied` field is ABSENT — there is no +> `state` field; an absent `applied` IS the unfinished marker — and whose key still appears in the +> aggregate's `appliedMovements` ring, or as a hold's `lastMovementKey`, is given its `applied` record +> by the sweeper **before** that key can be evicted from the ring. The recorded result is the ring +> entry's `result`, or `{ ok: true, reservationId }` when the witness is a hold's `lastMovementKey`. +> The residual therefore requires at least ring-size movements on one SKU between a crash and the next +> sweep. + +**Cross-SKU work is not atomic.** `adoptMany` and `commitMany` are N per-SKU writes (one +compare-and-set per SKU, not per id), each idempotent by reservation id, so a partial set is safe to +re-run; duplicate ids are collapsed first. `commitMany` **skips only an already-`committed` id**; a +`released` or `failed` one is reported `lost`, and a hold whose claim was abandoned before the hold +existed is also `lost`. So a SKU caught between its terminal record and its prune is completed by the +singular `commit` a replayer or the order-intent sweeper runs, **not** by re-running the batch. A +batch-only replayer therefore leaves a hold whose reservation is already committed: its units are +spent, so **every future expiry or reaping path must consult the reservation's terminal state before +returning units**, because returning a committed hold's units to the shelf is an oversell and the hold +looks live to anything reading only the aggregate. + +#### The contention budget, as numbers + +Read-modify-write on a hot SKU retries: bounded attempts with full-jittered backoff, ceiling +**†** `CAS_MAX_ATTEMPTS = 24`, first delay 2 ms doubling to a 50 ms cap. **This is a permanent budget** — +the aggregate is written by read-modify-write and there is no structural fix. + +**† The ceiling was raised from 12 to 24 on 2026-09-14, and the reason is that it is not one bound.** The +original 12 was derived from inventory's shape, where **depth tracks the units on one document** (below): +a writer loses at most M times before the guard turns every remaining caller into a clean refusal with no +write at all. The **order** document has a different bound, because refunds are arbitrated inside its +compare-and-set and a state flip contends with them: `2 × refunds-that-fit + 1 flip`. A shape with +concurrent reserves and finalizes on one order therefore sits legitimately near 12 rather than near M+1, +which made an exhausted budget a flake rather than a signal. The extra attempts buy jittered backoff on a +path whose only other outcome is the typed retryable error; they do not weaken any invariant, because +every invariant is enforced by the guard inside the write and not by the attempt count. The per-shape +assertions and the tests' own tighter hand-set budget are unchanged, and the tighter one is deliberately +kept below the package ceiling so raising the ceiling can never turn a shape green by accident. **A +change to the ceiling is still a change to the budget: measure first, then move it.** + +| Shape | Attempts asserted | Typed contention failures asserted | Reported measurement | +|---|---|---|---| +| 5 units, 50 racers, 20 loops (flash sale) | `<= 8` (`CAS_ATTEMPT_BUDGET`) | — | 5–6 attempts | +| 1 unit, 100 racers | `<= 8`, and `<= 6` | — | 2 attempts | +| restock +10 racing 40 reserves on 5 units, 15 loops | **not asserted** (logged per case) | **not asserted** | 12 attempts, 2–6 failures — **README measurement, no in-code figure** | +| restock then 40 reserves on 15 units, sequenced, 10 loops | **not asserted** (logged per case) | `<= 5` **per loop** (×10 loops) | 12 attempts, 0–1 failures — **README measurement, no in-code figure** | +| 20 removals racing 20 reserves on 12 units, 15 loops (**600 calls**) | `<= CAS_MAX_ATTEMPTS` | `<= 90`, i.e. 15% of calls | 12 attempts; **11–29** failures | + +**† The right-hand column predates the ceiling raise and is no longer the live figure.** The **merchant +removal** shape is the one shape that reached the old ceiling and raised the typed error; raising +`CAS_MAX_ATTEMPTS` took it two or three attempts deeper and its typed failures to **zero**, which is the +whole point of the raise — attempts the loop now has are failures the caller no longer sees. The numbers +here are kept only as the record of what was measured at 12. **The live per-shape tables live in +`packages/store-emdash/README.md`** ("Contention budget", and "Coupon contention, measured" for the +coupon counter), which is where they are re-measured; cite those rather than these, and do not re-copy +figures into this record, because they drift and this record does not. + +Three honesty notes on that table. The right-hand column is a **record of measurement, not an +assertion**: only the flash-sale shapes and the removal shape assert a depth at all, and the two restock +shapes merely log theirs per case, so a regression there is caught by their contention and conservation +assertions rather than by a depth ceiling. For the two restock rows the figures exist **only in the +package README** — there is no in-code comment or assertion carrying them, so nothing in the source +corroborates them and they should be re-measured rather than cited. **† The README/test disagreement this +paragraph used to name is closed.** It recorded that the removal shape's figure differed between the race +file's own comment and the README's table, and that the code comment was the one to trust; the README has +since been reconciled to the test, and the shape's figures were re-measured after the ceiling raise +besides. Note also that the sequenced row's ceiling of 5 is **per loop**, asserted ten times, not a +cumulative budget for the case. + +`CAS_ATTEMPT_BUDGET = 8` — which lives in the crash-seam suite, not in the package's own constants — is +asserted to be strictly below `CAS_MAX_ATTEMPTS`, and that separation is what makes the ceiling safe to +move: a hand-set budget below the ceiling cannot be satisfied by raising it. The two flash-sale +figures sit at M+1 and are stable across runs: only M writes can succeed before the guard turns every +remaining caller into a clean `OUT_OF_STOCK` with **no write at all**, so a writer loses at most M +times. **Depth tracks the units on one document, not the size of the crowd.** + +**One shape is asserted at the ceiling; two others were measured at it.** The merchant **removal** +shape is the asserted one, and the worst, because a **refused** removal still writes its ledger entry, +so its writes are not bounded by the units at all. The two **restock** shapes were measured at 12 as +well — a restock raises the unit count mid-race — but those are README figures with **no in-code +assertion**, so they are evidence, not a guarantee. The sequenced restock case is the regression +detector: it has no contention to hide behind, so its exact honour count fails if the retry loop +degrades. + +**Retry exhaustion is a typed retryable error, never `OUT_OF_STOCK`.** `ReserveResult` is +`{ok:true,reservationId} | {ok:false,reason:"OUT_OF_STOCK"}` and has no member for "too busy". +Exhaustion throws `StorageContentionError` — typed, `retryable: true`, structurally discriminated by a +`code` that survives a sandbox bridge, carrying the last retryable host abort as its cause. A shopper +who could have bought must never be told the item is gone. + +**Two gaps around that error, both named rather than papered over.** First, **the port does not document +it.** `ReserveResult` has no retryable member, and the `InventoryStore` contract names five typed error +classes — commit-lost, not-found, not-held, adjust-mismatch and stock-movement-mismatch — none of them +retryable. So a caller reading the port alone would not know a retryable outcome is possible: the port +docblock is **knowingly behind the adapter**, and recording the retryable outcome there is a +**docs-only `[Domain]` follow-up outside this work order**. This record does not change the domain. +Second, **the mapping to a retryable HTTP response is not built**: it will be wired at the cart-route +increment, and until then the error propagating uncaught is the intended behaviour, because it is loud. + +#### Where the built store corrects the plan + +| The plan said | The code does | +|---|---| +| reserve is one atom | a durable-claim **two-step** with two pre-claim exits | +| `reservation_outcomes/{key}` holds a copy of the terminal answer | there is **no second copy**: `reservation_keys/{key}` is promoted in place, so one collection carries claim and terminal. `reservation_outcomes` does not exist | +| `reservation_index` holds `{ sku }` | it holds `{ sku, idempotencyKey }` **plus** the terminal state | +| all four id-taking batch methods are `WHERE id IN (:ids)` | only `adoptMany` and `commitMany` take id sets; `adopt` is single-id and `releaseAdopted` is single-id **and** order-scoped | + +One further honesty note, **† now closed (2026-09-14).** This said `release` on a reservation that is +neither live nor already released still threw an **untyped** `Error`, exactly as the SQL store did, and +that typing it was an open follow-up. It **is** typed: `ReservationNotReleasableError`, an **adapter** +error carrying the reservation id, the state it was found in, and a structural `code` that survives a +sandbox bridge. It is adapter-level rather than the domain's `ReservationNotHeldError` because that class +is the port's `adjust` failure and its message would be false here; widening the port to cover `release` +remains a domain change with its own PR. The reason it needed typing at all is a real caller: the cart +expiry **swallows** this case, because a hold an order has already committed is not the cart's to return, +and an untyped error forces that caller to match on a message. The message text is unchanged from the +bare error it replaces, so nothing reading the text had to change. + +### 3.

First, **once-only lives in the redemption key document's own state +machine** — `claimed → bumping → applied | refused`, where `claimed → bumping` is a one-winner revision +compare-and-set and only the winner reaches the counter, every loser reading the winner's recorded answer +back. That is what lets the `updateIf` guard **carry the cap and nothing else** (§1): pinning a per-key +witness into the guard instead would turn the delta into a revision compare-and-set, making every +redemption contend with every *other* redemption of the same coupon so retry depth grew with the +**crowd** rather than the headroom — and it would not even be sufficient, because a peer's bump +overwrites the shared witness and a same-key replayer that no longer sees its own key there bumps again. +Second, **the bump right is leased**, because a step held by a slow owner and one held by a crashed owner +are the same document: it carries a deadline (`COUPON_BUMP_LEASE_MS`, 10 s, overridable per store as +`bumpLeaseMs`), a waiter takes it over only once that lapses, and until then it re-reads and finally +raises the typed retryable contention error so the caller's own retry reads the recorded answer. The +lease is re-asserted by a heartbeat compare-and-set immediately before every counter write, per retry — +the cross-cutting owner-token rule in the Amendment. The **residual is one HIGH, never one LOW**: a `+1` +that lands and then crashes before `applied` is recorded, with the lease lapsed and the witness +overwritten, over-counts by one and never under-counts, so the coupon can only ever refuse a redemption +it could have allowed. Exactness is restored by the coupon recount sweeper. + +**R1 — coupon redemption cannot roll back.** The SQL bumps the global counter and *then* counts the +customer's redemptions, and a per-customer refusal is undone by the **transaction**. A transactionless +store has no such undo, so the order is inverted: **claim `coupon_customer_caps/{couponId}:{customerId}` +first** by compare-and-set, then bump the global counter (`updateIf` guarded on `usesCount < maxUses` +when capped, an unguarded delta when uncapped — an uncapped coupon has no invariant to violate); if the +global bump is refused, **release the per-customer claim** as an idempotent compensation. The per-key +replay record is a **separate** document, `coupon_redemptions/{couponId}:{idempotencyKey}`. A crash +between the two writes leaves a claimed-but-unapplied redemption that the sweeper completes or +releases. The invariant to hold: **a per-customer rejection never consumes global headroom.** + +**R2 — the email lease has an OR and a negation.** The SQL claims on +`sent_at IS NULL AND status != 'failed' AND (lease_until IS NULL OR lease_until <= now)`, which the +filter algebra cannot express. Denormalize **one** indexed field, `emailDueAt`: `null` when the message +is sent or failed, otherwise `max(dueAt, leaseUntil)`. The candidate query is then one range on that +field. + +**† Corrected 2026-09-14 — the claim is a `compareAndSet`, not an `updateIf`, and the lock-free path does +not survive here.** This clause promised "a single `updateIf` guarded on `emailDueAt <= now` that sets +`emailDueAt = now + leaseLength` and increments attempts". Two fields and an increment are already past +what the tier is for (§1), but the deciding reason is a correctness one: the entry being leased is +**embedded in an order document** alongside everything else that order's writers touch, so the write has +to be a read-modify-write against that document's revision no matter how simple the guard reads. And a +claimant must know *why* it failed — a lapsed peer's lease is a takeover, an absent order is a bug — +which is exactly what `updateIf` refuses to report. So `emailDueAt` is the **candidate filter** and the +revision compare-and-set is the **claim**, with the range re-applied to the fetched document. This is +strictly stronger than the design asked for, and it is the shape every other lease in the package copied +(§1, and the cross-cutting owner-token rule in the Amendment). + +**R3 — the customer filter is a UNION, and it stays one.** It is not a convenience OR that can be +collapsed to a single equality. Orders are born with `customer_id = NULL` and are back-linked only at the +customer's **next** magic-link login, so at query time one human owns both linked rows and +not-yet-relinked ones: the port is explicit that a `customer_id`-only predicate **silently undercounts** +and a `buyer_ref`-only one **mislabels**, which is why the key is +`customer_id = :id OR lower(buyer_ref) = lower(:ref)`, folded but exact because it is an identity +predicate rather than a fuzzy lookup. + +The design therefore keeps the union and moves it into the value set. The order document carries **one** +indexed `customerKey = customerId ?? foldedBuyerRef`, rewritten by `linkGuestOrders`, and the filter +becomes **`customerKey in [customerId, foldedBuyerRef]`** — the filter algebra supports `in`, so this is +one clause on one indexed field, one row per order is preserved because a document matches a set once, +and `countOrders` shares the identical predicate. + +**The one narrowing this introduces, handed to the lists increment.** An order whose `customer_id` is a +**different** customer but whose `buyer_ref` folds to *this* customer's email matched the SQL union and +will **not** match `customerKey in [...]`, because that order's key holds the other customer's id. If a +contract case pins that edge, the lists increment must keep a **second** indexed `buyerRefLower` field +and resolve the OR another way — and must say so in its PR. Checking the contract for such a case is part +of that increment's work, not an assumption made here. + +The created-at window needs no denormalization at all: it is half-open +`createdAt >= from AND createdAt < to`, which maps to `gte`/`lt` directly. + +**R4 — live-sku uniqueness spans two grains.** `sku_owners/{sku}` is a claim document carrying +`{ ownerKind: "product" | "variant", ownerId, live: boolean }` — **†** and, as built, a `variantKey` for +the variant grain, a `claimedAt` that makes it a lease, and a `createsTarget` flag (both below). A +soft-delete or an orphaning **releases** the claim, and a new claimant may take over a released one by +compare-and-set. `SkuConflictError` outranks `SkuStockConflictError` exactly as today. The two partial +unique indexes' semantics — unique **among live rows only** — thereby become a document invariant instead +of a database feature the document store does not have. + +**† R4, amended 2026-09-14 — the claim is a LEASE, and it is taken before the write it protects.** A +claim taken and then abandoned by a process that dies cannot be given back in a `finally`, so a plain +claim document would strand the sku forever. It therefore carries an age and resolves to one of four +statuses — **held** (backed by a live owner document), **owed** (a peer still owes a stock carry on it, +so it must not be taken no matter how old), **in-flight** (young enough that its holder is presumed +alive) or **abandoned** (older than `CLAIM_ABANDON_AFTER_MS`, 60 s, overridable per store as +`claimAbandonAfterMs`), and only an **abandoned** one may be taken over. The lease is why the owner-token +rule exists: a writer parked past the abandon window is taken over, wakes, and would otherwise commit its +product write against a sku it no longer holds, leaving **two live rows on one sku** — so the claim's +revision is re-asserted by a heartbeat compare-and-set immediately before every sku-bearing product +write, on **every attempt** of the retry loop, and an overtaken writer is refused with `SkuConflictError` +(surfaced as `SKU_TAKEN`) rather than committing. Withdrawal is gated on a `createsTarget` flag recorded +on the claim, which says whether this claim **created** the target's inventory document or **adopted** a +pre-existing one: only a created one may be withdrawn, because withdrawing an adopted document would +delete units that were never this owner's. The accepted residuals are named in the Amendment. + +**R5 — `adjust` loses its qty CAS and is serialised by the document revision instead.** The SQL +serialised an adjust against a concurrent checkout on one hold with a CAS on the hold's own previous qty +(`WHERE … AND qty = :prevQty`), and a lost CAS **aborted the transaction** and re-ran the whole +choreography. There is no transaction to abort here, and no per-hold version to compare. The replacement +guard is **the inventory document's own revision**: any checkout-side change to that hold bumps the +revision, so a concurrent adjust's compare-and-set loses, re-reads, and applies the port's **absolute** +target against the hold's *current* qty — which is also why the built store re-derives from the hold +rather than trusting a remembered previous qty. The claim's recorded `fromQty` is audit, not a guard. +Proven by `adjust-concurrency.pg.test.ts`, re-pointed at the document adapter. See §7.12's guard-3 row. + +**R6 — refunds have a four-state capacity lifecycle.** The states are `recorded`, `reserved`, +`unverified` and `voided`. Every non-`voided` row **holds capacity**; `voided` releases it and stays as +an audit record. Arbitration is `activePrior + amount > ceiling` over that active sum, and it happens +**only** on the reserve/record path: `finalizeRefund` is **status-guarded** (`reserved` or `unverified` +only) and **never re-arbitrates**, because the reservation already holds the capacity. `voidRefund` and +`markRefundUnverified` are guarded flips out of `reserved`. All of it — the active sum, the arbitration +and the state flip — happens inside the order document's single compare-and-set. The three cases that +pin it are the ambiguous-timeout case (a `voided` row releases capacity while an `unverified` one holds +it), the fail-closed case (an already-refunded gateway voids the reservation and releases capacity), and +the status-guard case (a stray finalize never clobbers a voided row, and a same-ref re-finalize is a +benign duplicate). + +### 4.

That is +`reservation_index`'s reason (§2) applied six more times, and each is create-if-absent on its own id, +so the reverse lookup and the uniqueness are the same write. The package README's "The outbox locator" +and "Why two claim collections, where the design table names none" carry the per-collection detail, +including which bracket direction is healable. Two of the six answer a port method that takes a child +id the port never pairs with a parent — nine such methods across the two rules stores. And +`reporting_applied` is none of those six: like `coupon_redemptions` it is an IDEMPOTENCY claim +whose parent is known (the order the event belongs to, and the day document its effect lands +in), keyed by the event rather than by a lookup nobody else can serve — its second job is to +be revocable, since a recompute that counts an event absolutely must be able to stop that +event's delta from ever applying. + +**† The product document's index list has no `sku` and no `titleLower`, and `active` is filtered +through a text mirror.** Nothing queries `product_commerce` by sku — live-sku uniqueness is the +`sku_owners` claim, reached by document id, and a variant's sku is not a field of its product document +at all, so the index would answer half the question. `titleLower` is dropped because the port's title +search is a **substring** and the filter algebra has none, so declaring it would be a read contract for +a query never issued; that half of the search is resolved in memory over rows the indexed axes already +narrowed. `active` stays a boolean field the port reads back, but the *filter* binds `publishKey`, an +indexed two-value text mirror, because one dialect cannot bind a boolean as a `where` value. +`lifecycle` (a three-state tombstone axis — the algebra has no negation, the archive view needs one, +and a document may hold variants before its product row exists), `productKind` and `createdAt` are +added for predicates and ordering the admin list actually issues, and `productId` for the two batch +reads. The field-by-field difference is tabulated in the package README's "Two deviations from the +design's index table, both forced". + +**† Coupons are keyed by id, with the code as a claim document.** `redeem`, `findById`, `update` and +`delete` are all handed an id, and the money path must not pay a lookup to reach the counter; the admin +list is keyset-ordered on `(createdAt, id)`, which is the host's own total order only when the document +id **is** that id. This record's own `uniqueIndexes` table already offered the alternative for +`coupons.code` — "the document id, or a claim document" — and the store took the second. Codes are +unique after case folding, where the SQL unique index was case-sensitive; `findByCode` stays +case-sensitive by comparing the code the claim stores. `coupon_redemptions` gains three indexes for +reads that exist: `createdAt` (the reconciliation sweep both ranges and orders on it), `redemptionId` +(`release` is handed the generated id, not the document id) and `holdsUse` — a **string** mirror of a +boolean, the same device as `publishKey`, because a refused key keeps a permanent document and that +document must stay out of the delete guard, `releaseByOrder` and the sweep. The redemption's state and +its lease are deliberately **not** indexed: nothing queries by them. + +Two corrections against the plan's table. The `orders` customer index is `customerKey`, not `customerId` +(R3) — **† and, because a contract case pins the cross-customer buyer-reference edge, R3's conditional +fired: a second indexed `buyerRefLower` is declared alongside it, and the union is resolved as two merged +arms (§6).** And **`coupons` carries no `active` index** — the coupon table has no active or soft-delete +column at all, so declaring `active` would be a read contract for a field nothing writes. It does, +however, need **`createdAt`**: the admin coupon list is keyset-ordered on `(created_at, id)` with a +dedicated index behind it, and ordering by an undeclared field throws exactly as filtering on one does. +The list's only *filter* is a code search; its *ordering* is what `createdAt` serves. + +**Idempotency is always a document id.** Every claim is `compareAndSet(id, null, …)`, a DB-level +`INSERT … ON CONFLICT DO NOTHING` enforced by the storage table's PRIMARY KEY on +`(plugin_id, collection, id)`. Four ledgers that were their own tables — cart mutations, coupon +redemptions, order notes and per-order events — collapse *inside* their aggregate document or become a +claim document of their own. + +**The `uniqueIndexes` rule, stated so it matches the table above.** A unique index is declared where the +host's index sync would **benefit a read**, it is **never** the once-only enforcement, and it **may +coincide with the document id** — as it does for both rows that declare one, `sku_owners` and +`customer_emails`, whose natural key *is* their doc id. Declaring it there buys a lookup plan, not a +guarantee: the guarantee is the claim document and its create-if-absent write. It is worth being honest +about what that replaces, because today's SQL leans on database constraints as real backstops: + +| Today's backstop | Replaced by | +|---|---| +| `reservations.idempotency_key` UNIQUE | the `reservation_keys/{key}` claim document | +| `orders.idempotency_key` UNIQUE | the `order_keys/{key}` claim document | +| `refunds.idempotency_key` UNIQUE | the refund's own key inside the order document, plus `refund_keys` | +| `coupon_redemptions (coupon_id, idempotency_key)` UNIQUE | `coupon_redemptions/{couponId}:{idempotencyKey}` as the doc id | +| `order_emails_outbox (order_id, to_state)` UNIQUE | first-wins entry inside the order document | +| `cart_lines (cart_id, sku)` UNIQUE | one line per sku inside the cart document | +| `order_notes.idempotency_key`, `entitlements.grant_idempotency_key`, `payments.provider_ref`, `payment_events.dedupe_key` UNIQUE | each becomes the document id of its claim | +| `product_commerce`/`product_variants` live-sku **partial** unique indexes | the `sku_owners` claim document (R4) | +| `customers.email`, `sessions.token_hash`, `coupons.code` UNIQUE | the document id, or a claim document | + +One row of that table is a hazard rather than a translation. **`login_challenges` has no unique +constraint at all today** — its throttle is a count-then-insert with a genuine race window, and the +contract suite exercises the cap but not the race. The design **must not inherit that silently**: +whoever builds the identity adapters owns making the throttle a claim document (or recording +explicitly why it stays best-effort), rather than reproducing a count-then-insert on a store that +cannot even fall back to a constraint. + +### 5. The index rule has two halves, and they are not the same half + +**Declaration is a read contract.** A declared index is *required* to query or order by a field: an +undeclared field is not slow, it is a **runtime `StorageQueryError`** thrown by the where-clause and +order-by validators on every `query()` and `count()`. The adapter's own seam documents it as "a +programming error, not a runtime condition — the fix is to declare the index, which is why the declared +index lists are part of the read contract rather than a performance knob." + +**What is actually pinned today, stated truthfully.** The built inventory tier shares **one exported +layout constant** between the store and its harness, so a collection's declared indexes and its test +harness cannot disagree — but **nothing pins the literal collection names or index lists**, because the +assertion and the subject are the same constant. And the deployed descriptor declares no storage at +all: the staging config test asserts `descriptor.storage` is **undefined**. So the list in §4 becomes a +pinned read contract only when the descriptor declares it, at the descriptor increment, whose +`site-config.test.ts` must assert the literal lists. What **is** tested today is the read contract +itself — that an undeclared field throws rather than silently scanning. + +**Materialization is not a correctness guarantee.** The host's index sync logs per-index failures and +**never throws**, including for a unique index, so an index that fails to create degrades silently. +Worse, in both test tiers the index argument is only the queryable-field allow-list — the host's +index-materializing function is unexported, so **no tier creates a physical index and a `uniqueIndexes` +declaration enforces nothing there**. Hence the two-sided rule: **declare every queried field; never +let a unique index be the once-only enforcement.** + +**Timing.** Hand-registered plugins have no install handler, so the once-per-process index sync on the +scheduler tick is their sync moment; with a minute-granularity cron declared, indexes appear within a +minute of deploy. + +### 6. What the store cannot serve, and the decisions taken + +`query({ where, orderBy, limit, cursor })` and `count(where)`. The filter supports exact match, null, +`in`, prefix and the four range comparisons — **no substring, no negation and no OR**: a flat record +joined with `AND` only. + +1. **The orders-list search narrows to anchored prefixes. Ratified.** The old predicate is an OR of + three arms, and an AND-only filter cannot express it in one query. The user-visible narrowing is on + the **buyer-reference** arm: it stops matching mid-string. A domain (`example.com`), or any fragment + that does not start the address, returns **nothing** — not an error and not a partial answer. + **The narrowing will be documented in the screen's empty state at the lists/UI increment.** Widening + the domain port instead remains available as a separate change with its own PR. + + **† Amended 2026-09-14 — how the three arms are actually served.** This clause originally said all + three arms denormalize into **one** indexed field. They do not, and did not need to. As built they + are three: `searchKey` (the folded order id, one `startsWith`), `buyerRefLower` (the folded buyer + reference, one `startsWith`), and the `order_sku_index` pointer documents for the exact folded sku. + The composite-key concern the original wording carried is therefore moot — a partial id matches a + partial id and nothing else — and only the buyer-reference axis narrows. What makes three arms + legitimate is item 3's cursor; see the merge ruling below. +2. **Correlated existence (search by line sku)** → `order_sku_index` documents, written after order + creation, derived and idempotent (so needing no atomicity), healed on read and by the sweeper. **† + They are a second query, not a contribution to `searchKey`**, and each carries a copy of the order's + frozen `createdAt` so the arm is keyset-bounded rather than a full resolution of every order that + ever bought the sku. Keying them by the `(sku, orderId)` **pair** is what makes "an order carrying + two matching lines appears once" a property of the document id rather than a de-duplication step + someone can forget. +3. **Keyset pagination maps in shape but not in token. † Decided 2026-09-14: re-derive.** The domain + cursor is a value position; the host cursor is an opaque host-minted string whose seek re-reads the + cursor row by id, so a deleted cursor row breaks it. The adapter therefore **ignores the host token + and re-derives the position** from the port's own `OrderListCursor` (`{ createdAt, id }`): it seeks + with a coarse range on the declared index and applies the exact `createdAt DESC, id DESC` tie-break + in memory, because a true keyset tie-break needs an OR. A deleted cursor row is consequently **not a + paging fault** — the position still describes itself and paging continues from it — and the case that + pins it is written, where none existed anywhere in the tree before. + + **† The two-query merge is UPHELD, under one precondition.** The rejection below was written on the + assumption of an opaque host-minted cursor, and item 3 retired that premise. The ruling, stated so + the precondition travels with it: **an OR may be resolved as N indexed queries — each contributing + its own top `limit + 1` — merged and re-sliced, and counted by inclusion–exclusion over the SAME + predicate function, exactly when the cursor is a self-describing value position.** Both halves are + load-bearing. The cursor is what makes "strictly after this position" decidable for a document from + *any* arm, so each arm can be paged independently and the top `limit + 1` of the merge is the true + page; the shared predicate function is what keeps the count from disagreeing with the page it + captions. Under an opaque per-query token neither holds, and the rejection stands. Two ORs are + resolved this way as built — the customer union (`customerKey` and `buyerRefLower`, counted by + inclusion–exclusion) and the sku arm (counted as a set difference). + + **† The ordering invariant the merge needs, which is a one-dialect trap.** The adapter's total order + is `createdAt DESC, id DESC` in **code-unit** order, because that is the order the port's cursor + position is defined in. The host breaks its own `createdAt` ties on the id column under the + *database's* collation, and one dialect's default collation ignores punctuation at the primary level, + so host row order and code-unit order can disagree **inside a tie group**. The rule is therefore: + **an arm is drained to the end of its boundary `createdAt` tie group before anything is sliced.** + Truncating at the needed count in the host's row order lets a tied row fall off one page without + appearing on the next — a silent gap, on one dialect only, which is exactly what the proving case + observed when the drain was removed. +4. **`limit` is clamped by the host** (50 default, 100 ceiling), so reads that sum day documents page: a + one-year reporting window is four pages, not one. +5. **No raw SQL and no host DB handle**, ever. Nothing in this design needs one. + +### 7. The prose snapshot: what the old SQL guaranteed, and which document write guarantees it now + +The Kysely stores are deleted at the service-removal increment. This section is where their guard +semantics survive. Predicates are quoted as predicates, never as line numbers. Where a proving suite +does not exist yet it says so. + +#### 7.1 The guarded decrement — `WHERE on_hand >= qty` + +*What the SQL guaranteed.* `UPDATE inventory SET on_hand = on_hand - :qty WHERE sku = :sku AND +on_hand >= :qty RETURNING on_hand` — read, compare and write in one statement, so two shoppers could +never both pass the comparison and `on_hand` could never go negative. Zero rows meant out of stock, not +an error. +*Invariant:* **no oversell** (an engineering invariant named for its test, not a product claim). +*Now guaranteed by:* one compare-and-set on `inventory/{sku}` in which the comparison is computed in JS +and the decremented count **and** the hold record commit together — the decrement and the record of who +applied it are the same atom. +*Proven by:* `inventoryStoreContract` on every dialect and `no-oversell.pg.test.ts` on Postgres — "N +concurrent reserves against M units yield exactly M winners", over 20 loops — the only tier that can +lose a real race. + +#### 7.2 The claim flip — `WHERE state = 'pending'` + +*What the SQL guaranteed.* The reservation was inserted `pending`, then flipped by +`UPDATE reservations SET state = 'held' WHERE id = :id AND state = 'pending'` in the same transaction as +the decrement. The guard elected exactly one caller to touch `on_hand`. +*What the loser did — corrected.* The loser did **not** roll back work it had done: the guarded update +matched zero rows, so the decrement never ran and the transaction returned its lost verdict having +performed **no writes at all**. The caller then **polled** the reservation row — up to 200 attempts at +5 ms — and **echoed the winner's answer**, throwing an **untyped** `Error` if the row never reached a +terminal state. +*Invariant:* **once-only** on the money path. +*Now guaranteed by:* the ordering rule — the terminal answer on `reservation_keys/{key}` is written +before the hold is pruned, and the hold is itself the record of application. The document model's loser +does not poll and echo; it **completes the claim** and derives the same answer from the durable record, +so a stalled winner cannot leave a caller spinning against a deadline. +*Proven by:* the crash-seam cases that park each write in turn — claim-written-nothing-else, +compare-and-set-ran-terminal-never-written, terminal-written-prune-never-ran — plus the +**prune-before-terminal** case, the only test of the ordering rule and the one a prune-first store would +fail. + +#### 7.3 The adopt scope — `WHERE state = 'held' AND expires_at > :now` + +*What the SQL guaranteed.* `UPDATE reservations SET state = 'adopted', order_id = :orderId WHERE +id = :id AND state = 'held' AND expires_at > :now` — a hold already eligible for the expiry sweep could +never be adopted, and a `NULL` deadline never satisfied the comparison, so an unstamped hold was not a +checkout hold. +*The read-back carve-out, without which a replay would be wrong.* When the flip matches zero rows the +store re-reads and returns success if `state = 'adopted' AND order_id = :orderId` — **with no +`expires_at` re-check at all**. Only the initial flip tests the deadline; the idempotent-replay path +deliberately does not, so a replay of an already-adopted hold succeeds **past** its stamped deadline. +Dropping that carve-out would lose a hold the order already owns. +*Invariant:* **no adoption of units that have already gone back on the shelf** (not exactly-once +expiry, which is the cart's guarantee in 7.7). +*Now guaranteed by:* the same predicate read off the hold inside the aggregate document, carve-out +included, with the null-deadline refusal preserved deliberately — the in-memory fake treats an unstamped +hold as adoptable and is the **outlier**; reconciling the fake is a follow-up. +*Proven by:* `inventoryStoreContract`'s "`adoptMany` replay is idempotent — a row already adopted for +THIS order stays adopted even PAST its hold deadline". Note the singular `adopt` carries the identical +carve-out and has **no test at all** — a gap the new adapter's suite should close. + +#### 7.4 The batch classifications — `WHERE id IN (:ids)` + +*What the SQL guaranteed.* Two methods took id sets — `adoptMany` flipping +`WHERE id IN (:ids) AND state = 'held' AND expires_at > :now`, `commitMany` flipping +`WHERE id IN (:ids) AND state IN ('held','adopted')` — so a whole batch was classified and applied +atomically, misses classified by a read-back. The unknown-id behaviours differed on purpose: +**`commitMany` throws `ReservationNotFoundError`** (matching the singular `commit`) **while `adoptMany` +folds an unknown id into `lost` and never throws**. +*Correction to the plan,* which described all four id-taking methods as `IN (:ids)`: only those two are. +`adopt` is single-id, and `releaseAdopted` is single-id **and order-scoped** — an order may only release +a hold it itself adopted — and is an unconditional no-op on any miss, never throwing. +*Invariant:* **once-only** per reservation; a paid order never left with an un-committed hold. +*Now guaranteed by:* N per-SKU compare-and-sets, each idempotent by reservation id, plus +`reservation_index` written before the hold, which is what makes "unknown" **provable** and so preserves +the asymmetry. Set-atomicity is replaced by the order document recording the intent first and a sweeper +completing a partial. +*Proven by:* the contract's batch cases including the unknown-id asymmetry and "commitMany partial: a +released hold is lost; an already-committed hold is benign; a held hold commits"; the multi-line checkout +race across 3 SKUs, which asserts a batch never oversells **or half-commits**; and the partial-batch +crash seam. + +#### 7.5 The refund ceiling — `min(Σ captured, frozen total)` under a row lock + +*What the SQL guaranteed.* The order row was locked, the succeeded payments summed, the ceiling taken as +`min(captured, frozen total)`, and the refund arbitrated and inserted inside the same lock, so two +concurrent refunds could not each read the same headroom. +*What the lock actually was — corrected.* Not `FOR UPDATE`, which the SQLite dialect does not offer, and +**not** a self-assignment either: it is +`UPDATE orders SET updated_at = :now WHERE id = :orderId RETURNING id, state` — a **real column write**, +so every refund attempt genuinely bumps `updated_at`. On Postgres the row lock serializes concurrent +refunds; on SQLite writes serialize globally and it is a harmless no-op. The self-assignment trick +(`on_hand = on_hand`, `product_id = product_id`) and the "`FOR UPDATE` is not SQLite" rationale live in +the **product-commerce** store, not here. +*Invariant:* **the ceiling is never exceeded**; refund once-only. +*Now guaranteed by:* `payments[]` and `refunds[]` embedded in the order document with the active sum, +the arbitration and the insert all inside one compare-and-set — the revision check does what the row +lock did. `refund_keys/{refundKey} → orderId` exists because the settle path holds only the refund key +and an embedded array cannot be found by it without a scan. The four-state capacity lifecycle is R6. +*Proven by:* `refund-order-contract` — the short-capture case binding the ceiling at captured, the +over-refund past the frozen total recording nothing, repeated partials summing to the ceiling, and the +three R6 cases — plus `refund-race.pg.test.ts`, where N concurrent full refunds yield exactly one winner +and N concurrent partials stay sum-bounded under every interleaving. + +#### 7.6 The sku rename — two inventory rows locked in sorted order + +*What the SQL guaranteed.* Carrying stock from an old sku to a new one locked **both** inventory rows — +acquired as a pair, iterating the two skus in **sorted order**, so every writer agreed on one lock order +and two crossing renames could not deadlock (measured at roughly one loop in 250 before the sort +existed). Each lock was a portable self-assignment `UPDATE`. It then claimed the target row +(`ON CONFLICT (sku) DO NOTHING`, raising `SkuStockConflictError` if the claim was lost), moved the units, +wrote paired `rename_out`/`rename_in` ledger rows whose own conflict clause can never fail the move, and +short-circuited entirely for a sku that was never stocked. It refused the whole operation with +`SkuHeldStockError`, naming the sku and the count, if +`SELECT count(*) FROM reservations WHERE sku = :source AND state IN ('held','adopted')` was non-zero. +The avoidance was **not complete**, and was recorded as such: the product-side writers take a +unique-index lock before any inventory lock, so two products renaming onto each other's skus could still +deadlock, and a lock-order deadlock was never mapped to a typed error. +*Invariant:* **stock conservation** across a rename; no rename out from under a live hold. +*Now guaranteed by:* the intent-claim of §3 — source zeroed and stamped, target applying once by token, +source clearing. A fixed lock order is replaced by a fixed step order, and there is no lock to order — +which also retires the residual deadlock above. +*† The held-stock refusal is NOT structural, and that is an accepted weakening — corrected 2026-09-14.* +The clause this replaces claimed the refusal "becomes structural, because the holds it checks are in the +very document being written". It is not, because the ratified step order is **carry after the product +write**: the product's own document commits first, and only then does the move run. So a reservation +landing in that window leaves the rename **committed with the carry owed**, where the SQL — which +locked the source row before it counted holds — would have refused the whole operation atomically. What +an observer sees is a product whose sku is the new one while its stock is still under the old one: a +**phantom out-of-stock on the target, never an oversell**, because no unit is ever counted twice and the +source's units stay exactly where a release of that hold expects them. The source sku's claim is held +until the carry is terminal, so nobody else can take those units meanwhile, and a new rename of the same +owner is refused with the same `SkuHeldStockError` until it completes. Completion is not deferred to a +sweeper alone: **any later write on the product runs it first**, and the sweeper is the backstop. One +consequence worth stating because an auditor will look for it — **which route completed the carry decides +whether the audit trail is whole.** A completion driven from the product's own recorded intent, which is +what a later product write and the product-side sweeper leg both do, moves the units *and* writes the +paired `rename_out`/`rename_in` entries, because the recorded intent carries the command key they are +derived from. A completion driven from the **inventory document's stamp** — the replayer's and the +inventory sweeper leg's entry point — has no command key, so it deliberately writes **no pair** rather +than invent entries it cannot attribute. The trail can therefore be honestly incomplete for a rename that +crashed mid-flight, and only for that. The contract pins the sequential refusal, which is unchanged; the +window is reachable only by a concurrent reserve and the adapter's crash-seam suite drives it +deliberately. The package README's "What the carry cannot make atomic, stated exactly" is the full +statement. +*Proven by:* `product-commerce-store-contract`'s refusal cases at both grains, `sku-rename-ledger`, and +`sku-rename-race`/`variant-sku-rename-race` — including the crossing-renames case where one side refuses +typed and neither deadlocks, satisfied on documents by there being no lock at all. + +#### 7.7 The cart hold expiry transaction + +*What the SQL guaranteed.* One transaction re-checked the deadline, returned the units and deleted the +line, so a line could never be deleted without its units coming back. The re-check was the flip's own +guard: `state = 'held'` **and** either a stamped deadline at or before now, **or** an unstamped hold +older than the cutoff **that also has a cart-mutation ledger row** — an existence test which is what kept +the cart sweep from reaping a hold no cart created. Only the flip winner incremented `on_hand` and +deleted the line. *Invariant:* **exactly-once expiry.** *Now guaranteed by:* the intent-claim — a guarded +flip of the line to `expiring` (the once-only token), then the release, then the removal, with a sweeper +completing a partial. The null-deadline arm's scoping survives as a property of the cart document that +owns the line: a hold with no cart line is not the cart sweep's to reap. **†** One thing to be exact +about, because the SQL's guard was a single predicate and this is two steps: the indexed `holdExpiresAt` +is only a **candidate filter**, a deliberate **superset**, and both of the SQL's arms — the stamped +deadline at or before now, and the unstamped hold older than the cutoff that also has a mutation record — +are **re-applied per fetched document** before anything is reaped. The index narrows; it does not decide. +Checkout keeps the shape it already has — a single guarded flip whose `state = 'active'` predicate is +itself the write-once, so a replay reports "already done" rather than failing. *Proven by:* +`cart-store-contract`/`hold-expiry`, whose cases are the specification here — an expired hold is released +and its stock returns, a lazy read racing the sweep returns stock **exactly once**, a hold whose TTL was +reset between listing and release is not reaped, a non-cart hold older than the TTL is not reaped — plus +`cart-fence` and `no-oversell-cart.pg.test.ts`. + +#### 7.8 The coupon guard — `uses_count + 1 WHERE max_uses IS NULL OR uses_count < max_uses` + +*What the SQL guaranteed.* One statement incremented the counter only while headroom remained; zero rows +meant exhausted. The `OR` made an uncapped coupon unconditional in the same statement. The per-customer +cap was then checked **after** that bump, in the same transaction, by **counting** the customer's +redemption rows — race-free because the coupon-row update had already taken the row lock — and its +refusal was undone by **rolling the transaction back**, so a per-customer rejection consumed no global +headroom. *Invariant:* **no over-redeem**, and no global headroom consumed by a per-customer refusal. +*Now guaranteed by:* R1's inverted order plus an idempotent compensation, because there is no rollback. +**†** The statement above that the counter's guard is "one statement" survives exactly, and deliberately: +as built the `updateIf` guards the cap **and nothing else**, because once-only lives in the redemption +key document's `claimed → bumping → applied | refused` state instead (amended R1). The uncapped case is a +plain delta for the same reason the SQL's `OR` made it unconditional — an uncapped coupon has no +invariant to violate. *† Two divergences from the SQL, both narrowings, both recorded rather than +discovered.* First, **a refusal is recorded permanently**: a replay of an exhausted key answers exhausted +again even if headroom has since been released, where the SQL rolled its refusal back and kept no record +so a retry there could later succeed. A stable answer per idempotency key is the property the whole +document model rests on. Second, **the per-customer counter document exists only while a cap is in +force**, so adding or raising a cap later counts only the redemptions made while a cap was set — the SQL +counted rows and had no such window. The alternative, a per-customer index over the redemption documents, +was weighed and the bounded document preferred. *Proven by:* `coupon-store-contract`/`coupon-lifecycle` — +the per-customer cap case, the guest-checkout degradation case, and the same-key replay — and +`coupon-no-over-redeem.pg.test.ts`, where N concurrent redeems at cap M leave exactly M successes and two +same-customer concurrent redeems at a per-customer cap of 1 leave exactly one; **†** plus the same-key +shapes that pin the state machine — 20 completers of one key while 20 peer keys commit, capped and +uncapped — and the crash seam that pins the lease from the forbidden side, with the owner's increment +parked. + +#### 7.9 Order creation — `ON CONFLICT DO NOTHING` plus the snapshot inserts + +*What the SQL guaranteed.* The header was inserted with `ON CONFLICT (idempotency_key) DO NOTHING`. +*Corrected:* a returning-nothing insert did **not** short-circuit the whole call — the transaction body +returned its "not created" verdict, skipping every follow-on insert, and the caller then **loaded the +existing order by the idempotency key** and returned it as not-created. Also corrected: only +`order_items` is **multi-row**, and it is skipped entirely when the line array is empty; `order_totals` +and the shipping address are **single-row**, the address conditional on one having been captured. The +totals row is 1:1 by construction — `order_id` is the **primary key** of the totals table, so a second +insert is a key violation rather than a convention. +*Invariant:* **replay once-only** and **snapshot immutability** — price and title frozen at purchase, so +editing a product never rewrites an existing order's line items. +*Now guaranteed by:* one order document created by create-if-absent carrying header, items, totals and +address together, with `order_keys/{idempotencyKey}` claimed first and carrying the full intent so any +replayer can finish the create deterministically. Snapshot immutability becomes **structural**: the items +array is written only by the creating write and is typed `readonly`, and one-totals-per-order is +tautological once totals are a field. +*Proven by:* `order-store-contract` — "replay with the same idempotency_key returns the same order +(created:false)" and "a replay carries the shipping address exactly once (idempotent snapshot)" — +`order-flow.dialects.test.ts`, and the existing case asserting that editing a product never rewrites an +order line. + +#### 7.10 The transition — guarded flip plus event append plus outbox insert + +*What the SQL guaranteed.* One transaction flipped the state guarded on `id = :orderId AND +state = :fromState`, some callers adding a `hold_expires_at <= :before` predicate; then — **only if the +flip won**, a zero-row flip returning immediately — appended an event row with **no conflict clause at +all**, and inserted the outbox row with `ON CONFLICT (order_id, to_state) DO NOTHING`, itself gated on +the caller asking for an email. +*Correction to the plan,* which called the outbox write an upsert: it is a do-nothing conflict, so the +first enqueue for a target state wins and later ones are no-ops. +*Invariant:* **transition once-only**, **audit completeness**, outbox exactly-once per (order, target +state). +*Now guaranteed by:* ONE compare-and-set on the order document guarded on the revision **and** on the +current state being the expected from-state, writing the new state, the appended event and the +first-wins outbox entry together. "Flipped but no event" is structurally unreachable, as it already was. +*Proven by:* `order-transition-contract`, `order-timeline-contract`, `outbox-dispatch`. + +#### 7.11 The orders-list search — an OR of three arms, and why a join would double-count + +*What the SQL guaranteed.* A folded id-**prefix** arm **OR** a folded buyer-reference **substring** arm +**OR** an **exact** folded line-sku arm expressed as a correlated `EXISTS` over the order's own frozen +lines. The port states why the sku arm is an existence test and never a join: the list's contract is +**one row per order**, and an order with two matching lines must appear once — a join would return it +twice, inflate the `limit + 1` next-page probe, and make the count that captions the page over-count, +since the count shares the predicate. The two dialects planned the arm oppositely — one de-correlating it +into a hashed subplan, the other keeping it correlated — both confirmed by reading the query plan rather +than assumed. The sku matched is the one frozen onto the lines at purchase time, so a rename leaves +earlier orders findable under the sku they were bought as. Alongside it, the **customer** filter was its +own OR (`customer_id = :id OR lower(buyer_ref) = lower(:ref)`, folded JS-side), and the date filter was +half-open: `created_at >= :from AND created_at < :to`. +*Invariant:* **one row per order**, and the count agreeing with the page it captions. +*Now guaranteed by:* **† corrected 2026-09-14, because the lists adapter resolved this differently and +better.** Three indexed arms, merged, not one denormalized field: an anchored `startsWith` on +`searchKey` (the folded order id), an anchored `startsWith` on `buyerRefLower` (the folded buyer +reference — the one axis that narrows), and the `order_sku_index` pointers for the exact folded sku, +still derived from the **frozen** lines. One row per order survives twice over: the pointer's id is the +`(sku, orderId)` pair, so an order with two matching lines owns exactly one, and the count adds the sku +set as a **set difference** over the same predicate function rather than a second tally. The **customer** +half also remains a union and also became two arms rather than one `in` clause: R3's conditional fired +because a contract case pins the cross-customer edge — an order owned by one customer id whose buyer +reference folds to the queried reference — so `customerKey` and `buyerRefLower` are queried separately +and counted by **inclusion–exclusion**, which is what keeps an order matching both halves counted once. +§6.3 records the precondition all of this rests on: a self-describing value-position cursor. The +half-open window needs no denormalization at all: `gte` and `lt` express it directly. +*Proven by:* the list and count cases in `order-store-contract` on every tier, ADR-0017's refresh cases, +and a one-row-per-order case under a multi-line sku match. **†** The **deleted-cursor-row case is now +written**, and so is the four-order tie-group case that pins the §6.3 drain — the one case that fails on +a single dialect if the drain is removed. The store's own narrower statement, that a mid-string +buyer-reference fragment finds nothing, is pinned in its package tests rather than in the shared +contract, which deliberately asserts only the anchored floor so an adapter serving the unanchored +superset stays conformant. + +#### 7.12 Inventory store — the remaining guards + +| Old guard | Invariant | Now guaranteed by | Proven by | +|---|---|---|---| +| `commit`: flip `WHERE id = :id AND state IN ('held','adopted')`; on zero rows re-read and return if already `committed`, else raise `ReservationCommitLostError` (or `ReservationNotFoundError` when no row exists) | commit once-only; a hold that is not live can never be silently committed | the reservation's terminal state in `reservation_index` plus the live hold in the aggregate; both typed errors preserved | `inventoryStoreContract` for the batch path. The singular commit-lost throw has **no case in the shared contract file**, but it *is* asserted twice outside it — `order-flow.dialects.test.ts` ("commit against a released reservation throws the loud `ReservationCommitLostError`; against a committed one it is a benign no-op") on every dialect, and the document adapter's own crash-seam suite, which asserts the same class for an orphaned index entry. Folding a case into the shared contract remains worthwhile | +| `release`: `released` returns; any other non-live state throws an **untyped** `Error`; a lost flip inside the transaction is a **silent no-op** | stock returns exactly once | the same two reads, and a lost settle is still a silent no-op. **†** The throw is now **typed** — the adapter's `ReservationNotReleasableError`, naming the reservation and the state found — because the cart expiry deliberately swallows this case and must not do so by matching a message (§2) | `inventoryStoreContract` "commit finalizes; release returns stock; double-commit and double-release are no-ops"; "release(unknownId) rejects with ReservationNotFoundError" | +| `#applyStockMovement`: ledger claim `ON CONFLICT (idempotency_key) DO NOTHING`, then an unconditional increment (restock) or a guarded `on_hand >= qty` decrement (removal) | stock conservation; movement once-only | the `inventory_movements/{prefixedKey}` claim plus one compare-and-set on the aggregate, with the ring as the in-flight witness | `inventoryStoreContract`; `restock-concurrency.pg.test.ts` | +| the **key-consumption asymmetry**: an unknown sku throws inside the transaction, so claim and movement both roll back and **the key is NOT consumed**; a genuine `INSUFFICIENT_STOCK` is recorded in the ledger **inside the committing transaction**, so the key **IS** consumed | a refusal that is a fact about the sku is retryable; a refusal that is a fact about the stock is final | the document model reproduces it by ordering: the unknown-sku case exits **before** the claim is written, the insufficient-stock case writes the claim's recorded answer | `inventoryStoreContract` "unknown-sku reserve is OUTSIDE idempotency scope: the key is not consumed and stays usable once the sku exists" | +| `StockMovementMismatchError` when a movement key is replayed with a different sku, direction or qty | one key means one movement | the claim document carries the full intent, so the comparison is a read of the same document | `inventoryStoreContract` "a stock-movement key reused for a different movement is rejected, never ok for the wrong movement" | +| `adjust` guard 1: the ledger's recorded reservation id must equal the caller's, else `AdjustReservationMismatchError` | one adjust key means one hold | the same comparison against the claim document | `inventoryStoreContract` "an adjust key replayed against a different reservation is rejected, never ok for the wrong hold" | +| `adjust` guard 2: the reservation must be `held`, else `ReservationNotHeldError` (or `ReservationNotFoundError` for an unknown id) | an adjust never moves a hold that is no longer the caller's | read off the hold in the aggregate and the index's terminal state | `inventoryStoreContract` | +| `adjust` guard 3: the qty CAS `WHERE id = :id AND state = 'held' AND qty = :prevQty`; a lost CAS aborted the transaction, and the **whole choreography re-ran**, re-reading the ledger and the reservation rather than re-deriving in place | an adjust and a concurrent checkout on one hold serialize | **the inventory document's revision is the replacement guard (§3, R5)**: a checkout-side hold change bumps the revision, so a concurrent adjust's compare-and-set loses and re-reads, and the completion then applies the absolute target against the hold's **current** qty. Outcomes stay the port's own — `ok`, a genuine `OUT_OF_STOCK`, or the typed mismatch/not-held/not-found errors — **plus `StorageContentionError` on an exhausted budget, which the port does not document** (see §2: a docs-only `[Domain]` follow-up, not changed here) | `adjust-concurrency.pg.test.ts`, re-pointed at the document adapter | +| `reserve`'s FK carve-out: an unseeded sku aborted the insert on the foreign key, so **no row and no key** were written | an unseeded sku is a pre-claim rejection, outside idempotency scope | step 2 of §2 — an absent inventory document returns `OUT_OF_STOCK` and claims nothing | as above | +| `reserve`'s real once-only: `ON CONFLICT (idempotency_key) DO NOTHING` over a UNIQUE constraint | replay once-only | `reservation_keys/{key}` create-if-absent over the storage table's primary key | `inventoryStoreContract` replay cases | + +#### 7.13 Order store — the remaining guards + +| Old guard | Invariant | Now guaranteed by | Proven by | +|---|---|---|---| +| `claimNextEmail`: `sent_at IS NULL AND status != 'failed' AND (lease_until IS NULL OR lease_until <= :now)`, claimed by re-applying the same predicate and setting `status='sending'`, a caller-supplied `lease_until` and `attempts + 1` | a message is sent once; a crashed dispatcher's row becomes claimable again | **† corrected 2026-09-14:** R2's single `emailDueAt` field as the **candidate filter**, with the predicate re-applied to the fetched document and the claim taken by a **revision `compareAndSet`** on the order document — not the `updateIf` R2 first promised (see R2) | `outbox-dispatch` "a crashed dispatcher run leaves the row claimable again after its lease expires"; "a failed send returns the row to pending; the next dispatch delivers it exactly once" | +| **†** *(new 2026-09-14 — no SQL analogue)* settling an outbox entry by **entry id alone** | a message settled once; a lost locator never reads as "already drained" | `outbox_keys/{entryId} → orderId`, written **after** the flip that enqueued the entry, so the only reachable tear is "entry exists, locator does not" — which the settle path **heals** with one bounded walk of the `emailDueAt` index and then writes the locator so the next settle is a single read. The reverse ordering would leave a locator pointing at nothing, which nothing could heal. A walk that still finds nothing is **loud**, not quiet: an already-drained entry HAS a locator and never reaches the walk, so an unresolvable id means a live lease about to lapse and a second send — it raises the typed retryable `OutboxEntryUnlocatableError`, having written nothing. `maxOutboxPages` bounds the fallback **only**, and is a separate knob from `maxExpiryPages` on purpose: the two scans are bounded by different things, so squeezing one must not silently squeeze the other | the order crash-seam suite's locator cases | +| **†** *(new 2026-09-14 — no SQL analogue)* `recordPayment`'s provider reference, **globally** | one provider reference means one payment, across **all** orders | `payment_refs/{providerRef} → orderId`, create-if-absent. The SQL's `ON CONFLICT (provider_ref) DO NOTHING` was per-table and **silent**; this throws `PaymentRefConflictError` when the reference is already claimed by **another** order, and a payment against a missing order throws a typed not-found.

Louder is right — both states are real and both were previously + invisible — but each has a handler that must be written: a non-retryable acknowledgement plus an + anomaly for the first, a retry or the next tick for the second. **A third joined them:** a delivery + check carrying neither scope throws where the SQL adapter and the in-memory fake both return `false` + (§7.17). It is fail-closed either way, and it is unreachable from a route that has an order id or a + session — so the obligation is narrow: a caller that can construct a scopeless query must handle a + throw rather than read a `false` as "not entitled", and the domain fake still answers `false`, which a + later `[Domain]` change should reconcile. +- **Compensations replace rollbacks.** Where the SQL undid a write by aborting a transaction — the + coupon per-customer refusal above all — the document model must write an explicit, idempotent + compensation, and get its ordering right. +- **Reporting becomes write-time work**, with past-bucket decrements and paged reads. +- **†** **32 rows naming 35 collections** to declare and keep in step with the descriptor — their + index lists part of the read contract.

The decision itself — one document per aggregate, a coupling made idempotently completable and swept +— is **unchanged and reaffirmed**: nothing built needed a rule this record does not already state. + +**2026-09-14 (later): §4 rows corrected to the declared layout after the identity and misc +stores landed.** + +**2026-09-14 (later still): §4 gains the reporting rollups' claim collection, and the +`reporting_daily` row is confirmed as built. The rollups needed a second collection the +earlier table did not name — one claim per `(order, transition)` and per `(order, refund)`, +which is what makes a redelivered event a no-op — and its ordering against the counter +write is the tier's residual choice: the claim is written FIRST, so a crash leaves an +UNDER-count that the recompute repairs rather than money counted twice (rule (c)). The +recompute itself is a method on the adapter, and scheduling it is a later change, as item 7 +of the list below already says.** + +Three kinds of change are recorded, and they are worth keeping apart: + +- **Corrections.** Statements that were false. §1's `updateIf` count and tier name, §2's "`release` still + throws untyped" and its `CAS_MAX_ATTEMPTS` value, §3's R2 (the email lease is a compare-and-set, not an + `updateIf`), §6.1 (three arms, not one field) and §6.3 (the cursor is decided), §7.6's "the held-stock + refusal becomes structural", §7.11's single-field derivation, §7.13's lease row, §7.14's "the attach + guard becomes a read of the hold". +- **Additions.** Collections, indexes and guards that had no row: §4's claim and locator collections and + every index list that moved, and the new §7.13 and §7.17 rows. +- **Generalizations.** Four rules that recurred across the adapters and are now stated once, below. + +### The four cross-cutting rules + +These emerged independently in more than one adapter, which is the only reason they are stated as rules +rather than as adapter facts. + +**(a) For a leased or claimed step, the owner's document revision IS the owner token, and it must be +re-asserted by a compare-and-set immediately before every write it guards.** A lease's whole purpose is +to let a step be taken over from an owner that has died — and a dead owner and a merely slow one are the +same document. So the taker's rule (wait for the lease to lapse) is only half of it; without the other +half a writer parked past the window wakes up and commits work it no longer has the right to do. +Re-asserting the revision immediately before the guarded write shrinks that to the gap between two +adjacent statements, and it must run on **every attempt** of the retry loop, carrying the revision +forward from the heartbeat's own result. A failed re-assertion is a typed refusal, never a write. Three +sites, reached separately and identically: the **sku claim's** heartbeat before every applying product +write (R4, §7.16); the **coupon bump right's** heartbeat before every counter write (R1, §7.8); and the +**rules child claims'** re-assertion before every embed, with the mirror rule on the way out — a delete +**un-embeds first**, then releases only at a revision read *after* the un-embed and only if the claim +still names this parent. + +**(b) A claim document is the fast path, not the definition of existence.** Nine port methods across the +two rules stores take a child id the port never pairs with a parent, and the claim document is how they +reach it — but a claim can be orphaned by a crash, and answering "not found" from a missing claim would +strand an id that really is embedded. So an id-keyed read that does not resolve **falls back to a bounded +scan of the parent collection and re-establishes the claim**, and the create path's collision test runs +through the same lookup, which is what keeps one child id out of two parents. Three consequences follow, +and all three are surprising enough to state: such a read **may write**; it **may throw** the typed +page-limit error where the SQL could only return `null`; and the healing is automatic rather than +operator work. The cost is not uniform and the asymmetry is the point — a claim that resolves costs +nothing extra, and the checkout reads do not consult a claim at all, so they never heal and never pay. +The package README's "The one residue, and why it is healed rather than prevented" tabulates the cost per +call. + +**(c) A residual resolves toward over-refusal, never toward overselling or over-granting.** Where a +window cannot be closed without cross-document atomicity, the surviving state is chosen so the system +refuses something it could have allowed rather than allowing something it should have refused. The coupon +counter's two residuals — a release compensation and a crash after the increment — are both **one HIGH, +never one LOW**, so the coupon can only over-refuse. The sku rename's owed carry is a **phantom +out-of-stock on the target, never an oversell** (§7.6). Inventory's ring-eviction residual re-applies a +movement rather than inventing an answer. In every case exactness is restored by a **recount sweeper**, +not by a tighter guard — which is the honest division of labour: the guard is responsible for never being +wrong in the dangerous direction, the sweeper for eventually being exact. + +**(d) A lease constant is an operating parameter, so it is named, defaulted and overridable per store.** +Two exist: the sku claim's abandon window (`CLAIM_ABANDON_AFTER_MS`, **60 s**, option +`claimAbandonAfterMs`) and the coupon bump right's lease (`COUPON_BUMP_LEASE_MS`, **10 s**, option +`bumpLeaseMs`). Both are justified against the same retry budget rather than picked: a write that retries +at most `CAS_MAX_ATTEMPTS` (24) times with a backoff capped at 50 ms per sleep cannot legitimately hold a +step for more than about a second, so a 10-second lease is an order of magnitude of headroom over the +slowest honest owner, and 60 seconds is two — long enough that an in-flight writer is never mistaken for +a dead one, short enough that the residue heals without an operator. They are overridable because a test +needs to open the window deterministically and an operator on a slower host may need to widen it. + +### The residuals this amendment accepts + +Named rather than argued away, and each covered by a crash-seam case driven from the forbidden side: + +- **The heartbeat-to-write gap.** Re-assertion shrinks the takeover window to two adjacent statements; + it cannot remove it, because the re-assertion and the write it guards are different documents. The + exposure is bounded by one full lease. +- **Clock skew costs a spurious retry, never data.** Both leases are compared against a clock the owner + and the taker read separately. Skew can make a taker think a live lease has lapsed — at which point the + owner's next re-assertion fails and it refuses, which is rule (a) working, not failing. No invariant + depends on the two clocks agreeing. +- **An overtaken writer's empty target document survives** under the newcomer's sku, when the overtaken + claim had created it. `createsTarget` is what makes it withdrawable at all (R4); a claim that adopted a + pre-existing document must never have it withdrawn. +- **A carry completed from the inventory document's stamp writes no rename audit pair** — the replayer's + and the inventory sweeper leg's route, because the audit entries are derived from a command key that + route does not have, and an entry invented there would claim a movement it cannot + attribute. A completion driven from the product's **recorded intent** — a later product write, or the + product-side sweeper leg — does write the pair. So the trail is honestly incomplete only for a rename + that crashed mid-flight (§7.6). +- **The coupon counter's HIGH-only residuals**, per rule (c). + +### The sweepers the adapters now require + +**The sweepers are not designed here — the sweeper increment owns all of them**, including their +scheduling, their batch sizes and their anomaly reporting. This record's obligation is only to say which +ones the adapters as built now *depend* on, because a missing sweeper is a correctness bug (Consequences) +and that list has grown: + +1. **Inventory movement claims** — mark a claim `applied` while its key is still witnessed by the + aggregate's ring or a hold's `lastMovementKey`, before eviction can occur (§2's sweeper contract). +2. **Orphan reservation index entries, and claimed-but-never-completed reservation key documents.** +3. **Partial cross-SKU hold batches** — driven from the order's own recorded intent via the + `holdsPendingAt` index and the singular per-id calls, **never** by re-running the batch: a batch skips + an id already terminal in the index, so a SKU caught between its terminal record and its prune is not + healed by a replay (§2). +4. **Partial cart hold expiries** — a line flipped to `expiring` whose release or removal did not follow. +5. **Partial sku transfers** — an owed carry whose source is stamped. Note this one has an in-path + healer too: **any later write on the product completes it first**, so the sweeper is the backstop + rather than the only route (§7.6). +6. **† A coupon sweeper, which no earlier list named.** It completes or releases claimed-but-unapplied + redemptions, frees per-customer slots, and — this is the part rule (c) makes mandatory rather than + tidy — **recounts** the global counter, because the counter's accepted residuals are HIGH-only and a + recount is the only thing that restores exactness. +7. **Derived search pointers and reporting rollups**, as already recorded. + +The rules and product-commerce claim healers need **no** sweeper leg: both heal in-path by rule (b), and +the rules stores' residue is repaired by the next id-keyed read of the affected id. An orphaned claim +misleads no reader and strands no id meanwhile — every id-taking method answers exactly as it would for +an id that was never created, and the next create of that id takes the claim over. + +### Where the living detail is + +This record is the decision; `packages/store-emdash/README.md` is the detail, and it is the one to read +for anything measured or per-method. In particular: "Contention budget" and "Coupon contention, measured" +for the live per-shape figures — **do not copy them here, they drift**; "The admin list, the search and +the keyset cursor" and "The outbox locator" for §6; "What the carry cannot make atomic, stated exactly" +for §7.6's weakening; "The redemption state machine" for R1; "Two deviations from the design's index +table, both forced" and "Four deviations from the design's index table, all forced" for §4's index lists; +and "Why two claim collections, where the design table names none" plus "The one residue, and why it is +healed rather than prevented" for rule (b). + +**Still open, and not closed by this amendment.** The `InventoryStore` port docblock does not document +the retryable contention outcome of `reserve`/`adjust`, and the in-memory fake treats an unstamped hold +as adoptable where the port, the SQL reference and the document adapter do not — both are docs-and-fake +follow-ups in the domain, outside this record. The mapping of the retryable contention error to a +retryable HTTP response is still owed by the route increments. And §5's substance is unchanged: the +descriptor still declares no storage, so §4's lists become a **pinned** read contract only when it does. diff --git a/adr/0020-one-deployable-plugin-owns-commerce-truth.md b/adr/0020-one-deployable-plugin-owns-commerce-truth.md new file mode 100644 index 00000000..4758fae8 --- /dev/null +++ b/adr/0020-one-deployable-plugin-owns-commerce-truth.md @@ -0,0 +1,194 @@ +# 0020.

ADR-0001 is + referenced throughout this folder and it is easy to read "the service is removed" as + retiring it wholesale. It does not. ADR-0001's product shape — an EmDash plugin that turns + a site into a store, with the CMS owning content and commerce owning commercial fields — is + what still ships. What ADR-0002 made a deployment choice, and what this record settles, is + only *where the commerce implementation runs*. +- Amends: **nothing.** + +## Context + +ADR-0002 designed the plugin↔authority boundary as a **deployment choice over stable ports**, +and said two things would stay true regardless: that a separate service was *required* for as +long as the host's plugin sandbox lacked conditional writes, and that a service might *remain +preferable* even after those primitives landed, for five named reasons. + +The first has expired. The host's conditional-write primitives exist, ADR-0018 admitted the +plugin to own commerce truth on `ctx.storage`, and ADR-0019 gave that truth a document model +whose guard semantics are pinned by the same contract suites the SQL stores passed. The +`@otta-sh/service` and `@otta-sh/store-postgres` packages have been deleted. + +The second has not expired on its own; it has to be answered. ADR-0018 said so explicitly and +deferred it here. Keeping a second deployable "in case" is not free: it is a second secrets +store, a second database, a second deploy, a second set of migrations, and — the expensive +part — a wire format that every port change has to be mirrored into. The question is whether +any of the five reasons is worth that, **now, for a project that is pre-1.0, unlaunched, and +has no users**. That last clause is doing real work: every one of these reasons is a reason +one might *reintroduce* a service later on evidence, and none is a reason to *carry* one +today on speculation. + +## Decision + +**Otta is one deployable.** The EmDash site Worker, with the plugin registered trusted, runs +commerce in-process against the site's own database. There is no commerce service, and none +is kept on standby. + +### 1. ADR-0002's five reasons, answered + +Each is quoted as ADR-0002 wrote it, and each is **rejected — pre-launch, no users**. + +1. **"payment-secret / PCI isolation."** Rejected. The isolation was never as clean as the + phrase suggests — the site already terminated the buyer's session and already held the + CMS encryption key — and Otta is not in PCI scope: card data never touches our process + (Stripe Elements runs in the buyer's browser, per + [ADR-0012](./0012-storefront-checkout-loads-stripe-elements-in-the-browser.md)). What the + split actually bought was a smaller blast radius for the Stripe API secret, and that is a + real loss, recorded as such in §2 below rather than argued away. With no users and no live + keys in production, taking that loss now — with the mitigations in §2 — costs less than + carrying a second deployable to preserve it. +2. **"stable public webhook URLs."** Rejected, and inverted: the webhook URL is now + **permanently site-owned** (§3). A site the operator already has a domain for is a + *better* home for a stable public URL than a second Worker on `*.workers.dev`, which was + itself the source of the subrequest footgun the deployment guide used to be organised + around. +3. **"independent scaling."** Rejected. There is nothing to scale independently yet, and the + arbiter of stock and money truth was the single database in both designs — so + "independent scaling" meant scaling a stateless tier away from a ceiling it did not own. + The in-process design has the same ceiling and one fewer hop. +4. **"serving non-EmDash storefronts."** Rejected. No such storefront exists, and this is the + reason most clearly answered by re-derivation rather than by standby (§4): the domain + ports are unchanged, so a service for a non-EmDash consumer is a new adapter over an + existing contract, not a resurrection. +5. **"a merged-in plugin on Cloudflare pins commerce truth to D1 (sandboxed plugins are + D1-only)."** Accepted as a fact, rejected as a reason to keep a service. It is true: truth + now lives in D1. ADR-0019 measured what that costs — a per-aggregate compare-and-set + contention budget, stated as numbers and asserted by tests — and the storage seam is still + a port, so the constraint binds the *adapter*, not the domain. Pinning to D1 is a bound we + have measured, not one we have guessed at. + +### 2. The Stripe-secret trust widening, recorded + +This is the one genuine loss, and it is recorded rather than minimised. + +Before the fold-in, the payment and email credentials were environment variables on a +separate Worker or Node process — `STRIPE_SECRET_KEY`, `STRIPE_WEBHOOK_SECRET`, +`EMAIL_API_KEY`, the x402 facilitator secret. With no second deployable to hold them, they +move to the one operator-provisionable store the plugin has: **write-only plugin `kv`**, +under the existing `settings:*` convention (`packages/plugin/src/payment-secrets.ts`, +work-order increment C3). Every key there is an existing service environment variable, +renamed — nothing was invented. + +**What widened.** The Stripe API secret is now readable inside the same process that renders +storefront pages and the admin console, rather than living behind an HTTP boundary in a +process the storefront could only talk to over a narrow REST surface. A code-execution bug +anywhere in the plugin now reaches it. That is strictly more trust in one process than the +split design asked for, and no amount of `kv` discipline changes that. + +**What bounds it.** + +- Credentials are **write-only**: persisted only on a non-empty submit, never rendered back + into a block, and read through a fail-closed reader that folds `kv` errors, empty strings + and non-strings to `undefined`. +- Outbound egress is **not ambient**. The plugin's only egress is `ctx.http.fetch`, gated by + the descriptor's `allowedHosts` allowlist, which is resolved at **build** time — a Settings + edit cannot widen the perimeter, only a rebuild can. +- The domain stays IO-free (`domain-is-io-free`, enforced on every commit), so the packages + that hold the rules cannot be the ones that exfiltrate a secret. + +**One honest caveat.** `packages/payments-stripe` defaults its transport to `globalThis.fetch` +rather than `ctx.http.fetch`, unlike the email sender and the x402 facilitator client, which +both route through the gated egress explicitly. No current call site constructs the Stripe +gateway with a live transport, so this is latent rather than exploited — but whoever wires the +Stripe gateway into the in-process composition must pass `ctx.http.fetch`, or the allowlist +bound above does not apply to Stripe. + +### 3. The settle route is public, and the site-owned webhook endpoint is permanent + +**The requirement, as actually built and enforced.** Earlier planning called for a +**non-public** settle route, on the reasoning that a public one is reachable directly at the +host's catch-all and so bypasses the endpoint's own verification. That plan is **wrong on this +stack, and is superseded by what shipped.** A webhook is always unauthenticated, the host +binds its *private* plugin-route dispatcher only on the authenticated path, and an anonymous +request therefore only ever reaches `handlePublicPluginApiRoute`. A non-public settle route +cannot receive a webhook at all. + +So the route is registered **`public: true`** (`packages/plugin/src/plugin.ts`), and the trust +anchor moved in with it: + +- **The Stripe HMAC is the anchor.** The plugin route performs a real signature verification + over the exact delivered bytes against `settings:stripeWebhookSecret`, unconditionally, and + no token or setting can switch it off. The bytes are base64-passed and never parsed, because + a `JSON.parse`/`stringify` round-trip is a different byte string and would fail verification + for every genuine delivery. +- **An edge token is the cheap outer gate in front of it.** `OTTA_WH_TOKEN` (a Worker secret + on the site, mirrored into plugin `kv`) lets the public route refuse an *unattributed* + request before it reads another key, builds a gateway or opens a store. It **passes through + when unset** — an unprovisioned deploy degrades to "cryptographic anchor only", never to + "nothing is checked". + +The requirement this record fixes is therefore: **the settle route is public and must stay +public; its defence is the unconditional HMAC, with the edge token as a pre-filter.** A future +change that makes it non-public is a change that stops webhooks working. + +**Gap, named rather than implied.** The admin route's `public: false` is pinned by an +assertion; the settle route's `public: true` is currently **not** pinned by any test, lint +rule or CI check — it is a manifest literal plus commentary. Pinning it is owed. + +**The endpoint is permanent.** Stripe delivers to `POST /webhooks/stripe` on the **site** +(`sites/staging/src/pages/webhooks/stripe.ts`), a transport shim that holds no secret and +verifies no signature; it exists only because the host's route framework JSON-parses a +route's body before any handler runs and exposes no raw-body read. There is no future in +which this endpoint moves back to a separate service: the URL is the operator's, on the +operator's domain, and a registered webhook URL is the kind of thing that must not move. + +### 4. A future service is re-derived, never resurrected + +If a service is ever needed — a non-EmDash storefront, a genuinely independent scaling need, +a customer who requires the isolation §2 gave up — it is **built new from `@otta-sh/domain`, +whose ports are unchanged by this record.** It is not restored from deleted code, and no +service is kept on standby, behind a flag, or in a branch. + +This is exactly the payoff ADR-0002 designed for, claimed once rather than twice: the seams +are what make deletion cheap *and* what would make re-derivation cheap. Deleted code that has +to be rebased over a year of domain changes is a liability; a port that never moved is an +asset. The contract suites are the acceptance test for either direction — a new transport +adapter is done when the existing suite passes against it, the same rule that admitted the +in-process client. + +## Consequences + +- **One deployable, one database, one secrets story.** No service URL, no service token, no + second migration set, no wire format to keep in sync with the ports. The deployment guide + describes one shape. +- **A wire format stops being a public contract.** The REST API was a 1:1 serialization of the + ports, and keeping it honest was real work. That work is gone — and so is the drift test + that guarded it, which is a small loss of evidence, not of correctness: the ports themselves + are still pinned by the contract suites. +- **The blast radius of the plugin process grew** (§2). This is the cost of the decision and + it is accepted knowingly, on the grounds that the project is pre-launch with no users and no + live credentials in production. It is not a cost that gets cheaper with scale. +- **Rollback is "revert the merge", not "switch modes".** There is no second mode. Nothing in + the tree can be flipped back to HTTP, and the deployment guide carries no asymmetric-rollback + caveat because there is nothing asymmetric left to roll back. +- **D1 is the storage floor** (reason 5). Its contention behaviour is a measured budget in + ADR-0019, and a workload that exceeds it reopens the *adapter* choice, not the boundary. + +**What would reopen this decision.** A real non-EmDash consumer; a measured contention or +volume figure that no document-model change brings back inside ADR-0019's budget; or a +compliance requirement that genuinely needs the process isolation §2 gave up. In every case +the answer is a new adapter over the unchanged ports — and in every case the evidence comes +first. diff --git a/adr/README.md b/adr/README.md index a6664741..11b42f20 100644 --- a/adr/README.md +++ b/adr/README.md @@ -31,11 +31,11 @@ than rewriting history. ## Records - [0001.

Four pieces of the standalone + * `@otta-sh/service` package's admin route layer (now deleted) are behaviour + * rather than framing, so they are mirrored here and named so the two could be + * compared by eye: + * - the orders list's opaque cursor (position + filter + limit, base64url JSON), + * its RE-VALIDATION on decode, and the fail-closed disagreement check between + * a token's filter/limit and the caller's — plus the client-side recovery that + * re-issues page one and flags `cursorRejected`; + * - the order serializers (`serializeOrder`, `serializeOrderSummary` from + * `routes/orders.ts`, plus the customer-context / timeline / refund / note + * serializers in `admin.ts`), field for field; + * - the per-command idempotency FALLBACK keys the route mints when a caller + * sends no header (`admin:transition:…`, `admin:cancel:…`, and the rest), so a + * header-less double-submit dedupes identically on both tiers; + * - the REFUND CEILING, which is arithmetic the route composes rather than a + * use-case it calls: `Σ captured` (succeeded payments only) and the frozen + * order total give `computeRefundCeiling`, `Σ active refunds` (status ≠ + * `voided`) is subtracted, and the remainder floors at zero. The three summands + * are real `@otta-sh/domain` exports; the COMPOSITION lived in the route, and + * now lives here too. + * + * TWO RECORDED DIVERGENCES, neither of them accidental: + * - NO GATEWAYS ARE COMPOSED YET (INC-C1/C3 move the payment adapters). The + * refund POST therefore reaches the route's own "no gateway wired for this + * order's method" arm and answers `409 REFUND_GATEWAY_UNAVAILABLE`. The whole + * path in front of it — input bounds, the REQUIRED idempotency key, the order + * lookup — is ported faithfully, so when a gateway map arrives the one line + * that changes is where it comes from. + * - a refund ROW here carries no `status`.

The sole implementation of `ReportingSettingsSurface`: the + * same six methods, the same argument shapes, the same RETURN VALUES — every field + * the `*Wire` types carry — with the `@otta-sh/domain` reporting/settings use-cases + * composed over the `@otta-sh/store-emdash` adapters bound to `ctx.storage` + * instead of a commerce service.

The wire type marks it + * optional for exactly one reason — a service older than the field omits it — and + * this tier is not that service. `0` is the FACT "nothing came back in this + * bucket"; the KEY's absence would be the different fact "this transport cannot + * report refunds at all". Dropping a zero here would collapse the two and stop a + * renderer from ever being able to tell them apart. + * + * A LOW-STOCK ROW IS NEVER TITLED WITH ITS SKU. `title` is the live product's + * title or `null`, and null is the only fallback — the port's rule, passed + * through unchanged. Four distinct causes produce null (no sku claim, a released + * claim, a claim held by a VARIANT rather than the product row, or a live product + * whose own title is genuinely null), and all four mean "we do not know its + * name", which is not the same statement as "it is called SKU-42". + * + * TOP PRODUCTS GROUPS BY `(productId, title)`, not by the product. A product sold + * under two titles is legitimately two rows, because the line snapshot froze the + * title at purchase time and the title is a fact about the SALE. Merging them + * would rewrite history to whatever the product is called today. + * + * AN EMPTY PERIOD IS OMITTED, never zero-filled. Zero-filling is a renderer's job + * and it needs the report's own silence to know which days it is filling; a + * report that invented the zeros would leave nothing to distinguish "no orders" + * from "no data". + * + * HOW A REFUSED INPUT SURFACES. The request schemas that stood in front of the + * `/reports/*` and `/settings` routes are mirrored below through + * `commerce-input.ts`, and a refused input SHAPE — a malformed instant, an + * interval or metric that is not one, a limit or threshold out of bounds, an + * empty idempotency key — REJECTS with a structural `INVALID_INPUT` naming the + * field, exactly as the rules and products clients do. It never resolves to a + * synthesized status, because there is no wire here to have one. + * + * `updateSettings` IS THE ONE METHOD THAT DOES NOT THROW for a refused VALUE, and + * the distinction is deliberate: the wire type's whole purpose is that a bad + * `holdTtlMinutes` comes back as `{ ok: false }` for the form to render inline + * rather than as an exception the page has to catch. So input SHAPE rejects and a + * refused VALUE resolves — the same split the HTTP tier has, where the 400 body + * is a result and a transport failure is a throw. + * + * AND THE FAILURE ARM CARRIES `reason`, NOT A FABRICATED `status`.

Four of these legs are the + * service worker's `scheduled()` handler moved in unchanged; the other five are + * the completers ADR-0019's two-tier write strategy always owed and that nothing + * had yet run on a schedule. + * + * EVERY LEG IN ITS OWN TRY/CATCH, WITH ITS OWN LABEL — mirroring the service's + * `scheduled()` handler, and for its reason: a sweep that throws must not starve + * the eight beside it. A tick therefore always returns a summary, and a failed + * leg is a `{ ok: false, error }` row in it rather than a rejected hook. + * + * AND EVERY LEG LOGS, which is the other half of that mirror and was missing from + * the first cut of this file. The summary is the hook's RETURN VALUE and the host's + * cron executor does not persist it, so a leg that fails forever would otherwise be + * indistinguishable from a leg that has nothing to do — exactly the failure mode an + * unattended path must not have. Each leg emits one `[otta] cron sweep …` line on + * success and one `console.error` with its own label on failure, matching the + * format the standalone commerce service's `scheduled()` handler used before it + * was folded into the plugin. An anomaly is louder + * still: it is logged AND written to the order through `flagReconciliation`. + * + * EVERY LEG IS IDEMPOTENT, which is what makes running them every fifteen minutes + * safe and is the property the suite pins with two ticks and one effect. None of + * them is a "do the work again" path: each finds outstanding work from the + * documents themselves and completes it exactly once, because the completion is + * always a guarded write the second caller loses. + * + * DISCOVERY IS INDEX-ONLY. A declared index is a READ CONTRACT (D3): filtering on + * a field the collection never declared *throws* `StorageQueryError` rather than + * running slowly. So every scan below filters on a declared field — `holdsPendingAt` + * for the hold intents, `createdAt` for the index heal and the product scan, + * `createdAt`+`holdsUse` for the coupon orphans — and anything else is decided + * from the document once it is in hand. + * + * NO SCAN MAY STARVE, and this is the property the first cut got wrong. A sweep + * that pages a collection `createdAt ASC` from a FIXED lower bound, capped at a + * page budget, reads the same oldest rows on every tick forever: past that budget + * the tail is unreachable and the gap never heals, silently. So every unbounded + * collection here is walked behind an ADVANCING CURSOR kept in `ctx.kv` (the + * plugin's own ungated store): + * + * - `order_sku_index` and the coupon orphans walk FORWARD: the cursor is the last + * `createdAt` read, less a small overlap so a row written slightly out of order + * is still seen, and a tick that runs out of budget resumes where it stopped. + * - the product catalog ROTATES: there is no "swept" marker on a product to narrow + * by, so the cursor advances to the end and then wraps to the beginning. Every + * product is reached within one rotation regardless of catalog size. + * - the hold intents need no cursor: `holdsPendingAt` is null once the order owes + * nothing, so that predicate narrows by itself as the work completes. + * + * A LOST CURSOR IS ALWAYS SAFE. It costs a re-read, never correctness: every leg's + * work is a guarded write, so re-reading a row it already handled does nothing. + * That is why a `ctx.kv` failure is logged and shrugged off rather than failing the + * leg — the sweep is strictly better off running without a cursor than not running. + * + * THE TWO HAZARDS, both named because both are easy to re-introduce: + * + * 1. `commitMany` SKIPS a reservation id already terminal in `reservation_index`, + * so a partial commit can never be healed by replaying the batch. The + * hold-intent leg therefore drives the ORDER STORE's per-id completers + * (`completeHoldAdoption`/`completeHoldCommit`/`completeHoldRelease`), which + * walk the order's own recorded intent one reservation at a time. Nothing here + * may reach for a batch method. + * + * 2. Those completers read a NON-VERSIONED `get`. Between that read and their + * per-id writes the order can legitimately move on — an order that expired + * mid-adoption has had its holds released by the expiry path, and the adoption + * completer will then report those ids as `lost`. That is normal, not an + * anomaly. So a non-empty `lost` set is RE-READ against the order's current + * `state` before it is counted: only a `lost` id on an order still sitting in + * the state that owns the intent is a real anomaly — and one that survives that + * filter is written to the order with `flagReconciliation`, because ADR-0019 + * §7.13 says an anomaly must always be RECORDABLE and a return value nothing + * reads is not a record. + * + * THE HOLD-TTL PARITY GAP CLOSES HERE. `in-process-commerce-stores.ts` records it + * as a MUST-CLOSE item and says where it closes: "with the settings and scheduled-sweep + * wiring, where the value is loaded once and the sweeps that expire holds run".

The + * service guarded `/grant` with `X-Internal-Token` because it was a + * server-to-server POST from the page layer. In the plugin there is no such + * channel: EmDash binds its PRIVATE route dispatcher only on the authenticated + * admin path, so a storefront request reaches `handlePublicPluginApiRoute` or it + * reaches nothing. `public: true` means "no session", never "no auth". + * + * THE FOUR CHECKS, in order, and why the order is the security property. Review + * round 2 (re-reviewers A1/B1/B2) found the first cut of this route standing on + * the facilitator alone, which is one layer where its Stripe sibling has two and, + * worse, which left the receipt→order binding to an amount equality: + * + * 1. The `X-Otta-Wh-Token` EDGE token (shared with `webhooks/stripe/settle`, + * `edge-token.ts`), compared in CONSTANT TIME, PASS-THROUGH WHEN UNSET. It + * runs FIRST so an unattributed request costs one kv get and, critically, no + * METERED facilitator call — this route's expensive work is a third-party API + * request and a Worker subrequest, which is precisely what a cheap outer gate + * exists to stop a stranger from spending. + * 2. The ORDER, loaded before any egress: it must exist (404) and its + * `paymentMethod` must be `"x402"` (400). The service's `/grant` could skip + * this because `requireInternalToken` meant only the page layer could reach + * it; anonymous, it cannot. Without it an x402 receipt settles a STRIPE order + * of equal total — and every order a storefront deployment holds is a Stripe + * order today, so that was the route's entire reachable effect set. + * 3. The FACILITATOR, unconditionally, with no branch that can skip it. A forged + * receipt for an on-chain settlement that never happened is refused by the + * only party that can actually know. + * 4. The TX-HASH BINDING, inside `settleOrder`: a receipt whose `transaction` is + * already recorded against a different order is a terminal `RECEIPT_REBOUND` + * (§ step 2b there). One settlement consumes one on-chain payment — the claim + * `@otta-sh/payments-x402`'s header makes, now enforced rather than assumed. + * + * Checks 1 and 2 REDUCE what the facilitator is asked about; they never substitute + * for check 3 or 4, and there is no configuration under which either is skipped. + * + * WHAT THE RECEIPT DELIBERATELY DOES NOT CARRY. The service returned the FULL + * serialized order on success, which it could afford behind its token gate. This + * route is public, so it states the OUTCOME and nothing about the buyer — no + * email, no lines, no totals (ADR-0010 §2's redaction rule applied at the surface + * that needs it).

A facilitator that + * REJECTS the proof is a terminal 400. A facilitator that could not be ASKED — + * outage, timeout, garbage body — is a 503, because the buyer's money has + * already moved on-chain and a transient blip must not become a permanent + * refusal no retry can undo. `@otta-sh/payments-x402` carries that distinction + * out of the adapter as `X402FacilitatorUnavailableError` (a throw, mirroring + * `payments-stripe`'s `PaymentIntentError({retryable})`, because + * `ConfirmationResult`'s failure union is closed and all three of its reasons + * are terminal); this is the surface that turns it into a status. + * + * NO CREDENTIAL, of any kind, appears in a value this module returns: every + * refusal is one of a fixed vocabulary of `reason` strings, and the caught + * facilitator error is dropped rather than interpolated. + */ +import { + cents, + currency as toCurrency, + orderId as toOrderId, + settleOrder, + type SettleDeps, + type SettleResult, + type X402Proof, +} from "@otta-sh/domain"; +import { X402FacilitatorUnavailableError } from "@otta-sh/payments-x402"; +import { createInProcessCommerceStores } from "../commerce/in-process-commerce-stores.js"; +import { edgeTokenAccepted } from "../edge-token.js"; +import { IN_PROCESS_EGRESS_URLS } from "../manifest.js"; +import type { RouteHandler } from "../types.js"; +import { x402GatewayFromCtx, type X402Egress } from "./x402-wiring.js"; + +/** The PUBLIC route path an x402 page-gate proof posts to.

EmDash's route framework JSON-parses the + * request body before any handler runs and exposes no raw-body read, and a + * Stripe HMAC is computed over the EXACT delivered bytes — a re-serialized JSON + * object is a different byte string and would never verify. The caller therefore + * base64-encodes the raw bytes; this handler decodes them and hands the + * byte-identical buffer to the gateway. + * + * WHY THE STATUS IS IN THE BODY. The same framework wraps a handler's return in + * `{success, data}` at HTTP 200, and Stripe's retry logic keys on the STATUS. So + * this route returns the status it WANTS as a field, using exactly the mapping + * `service/src/routes/webhooks.ts` used, and the calling site replays it onto the + * real response. Keeping the table identical is what stops Stripe's retry + * semantics from drifting when the transport changed underneath them. + * + * NO SECRET, of either kind, appears in any value this module returns: the + * results below are a fixed set of `reason` strings, and neither the edge token + * nor the webhook secret is ever interpolated into one. + */ + +import { settleOrder, type SettleDeps, type SettleResult } from "@otta-sh/domain"; +import { StripePaymentGateway } from "@otta-sh/payments-stripe"; +import { createInProcessCommerceStores } from "../commerce/in-process-commerce-stores.js"; +import { edgeTokenAccepted } from "../edge-token.js"; +import { stripeWebhookSecretFromKv } from "../payment-secrets.js"; +import type { RouteHandler } from "../types.js"; + +/** The PUBLIC route path a forwarded Stripe webhook posts to.

The storefront slice never asks; an admin slice handed a + tier without it throws at collection rather than running empty (`assertAdminClients`). +- **`AdminClientSurfaces` is optional per surface, and `requireSurface` is how a slice reads one.** + Only `products` is non-optional, because it was folded in first (INC-B10b-i); `orders` has both + tiers too now (INC-B10b-ii) and stays typed optional deliberately, so that it is read the way + every later surface will be, and so does `rules` (INC-B10c-i) and `reporting` (INC-B10c-ii, + which is the whole admin surface). The alternative was a + stub — an empty `listOrders`, a zeroed `getRevenue` — and a stub makes a slice *pass* against an + implementation that does nothing, which is worse than a missing run because it is + indistinguishable from evidence. So a slice reads its surface through + `requireSurface(tier, surfaces, key)`, which throws naming the tier and the surface it lacks: the + gap lands in a test report and closes by wiring, never by softening a case. Every surface is + wired and read through it today — `orders`, `rules` and `reporting` alike — so there is no + surface a slice can reach for and not get, and the next one added must arrive the same way + rather than through `?.`. +- **The reporting cases read their window back out of the data, never off the wall clock.** Each + tier stamps `createdAt` from its own clock and only one of them has a hook, so a case seeds + first, reads the instant its own order came back with, and asks for the four-day window around + that (`windowAroundOrder`). A pinned literal, or `Date.now()`, passes on one tier and silently + reports an empty period on the other. +- **No new `arrange` hook came with the rules slice, on purpose.** Its one cross-aggregate case — + `deleteTaxClass` refusing with `in_use_by_products` — points a product at a class through the + **`products` surface** the same composition already hands back (`getProduct` for the CAS token, + then `updateProduct`), rather than through a new seeder. An arrangement that only a client + surface can express belongs to that surface: a hook reaching behind it would prove the guard + against state no operator could have created. +- `reset()` may be a no-op **only while every case uses disjoint ids and no case depends on + another's leftovers**. One tier does the real thing (it rebuilds cheaply); the other documents + the no-op, which is why **every case addresses disjoint ids, skus, cart ids, coupon codes, zone + and method ids, idempotency keys — and its own email**. A shared address would let one case's + claimed order appear in another's list. +- **`session(email)` mints a real session through the login the transport genuinely has** — never + by writing a session row behind the port's back. One tier issues the challenge through its + credential verifier, because it dispatches no mail yet and the token rides in no reply; the other + is started with a capturing mail sender and reads the challenge out of the captured message. Both + redeem it through the **client's own** `verifyLogin`, which is the half the cases are about. +- **`order`/`address`/`shippingMethod`/`coupon`/`taxClass` seed through the `@otta-sh/domain` + ports**, in one + shared implementation (`test/helpers/commerce-tier-arrange.ts`) that both tiers hand their own + adapters to. Two hand-written copies of an arrangement drift, and a case that then fails on one + tier says nothing about the transport, because the setups were not the same. +- **Which seeding path:** a case whose *subject* is a write method calls it directly — + `upsertProductCommerce`, `createCart`, `addCartLine`, `createOrder` are under test in their own + cases and must not hide behind `arrange`. A case that merely needs a product, cart, session, + order, address or rule uses `tier.arrange.*`. **A state with exactly one writer is arranged + through that writer**, even across slices: the admin products cases reach a soft-deleted row and a + sku under a live cart hold through the tier's own *storefront* client + (`softDeleteProductCommerce`, `addCartLine`), because the admin surface reads both and mints + neither, and a hand-seeded row would prove nothing about the state the refusal guards. +- **A product that will be ORDERED must be arranged with a `title`.** Order pricing snapshots the + price *and* the title onto the line at purchase time, so an untitled row is refused + `PRODUCT_NOT_PRICED` — the same token an unpriced row gets. + +## The two optional hooks + +`clock` and `payments` are optional, and each gates exactly one case that names its gate **in its +own title**, so a test report says which tier skipped what without anyone reading this file. + +| Hook | What it is | Who has it | Who does not, and why | +|---|---|---|---| +| `clock.advance(ms)` | moves the one clock every store in the composition shares | the tier whose backend is rebuilt per case | a tier standing **one** long-lived backend for the whole slice: winding its clock forward expires every other case's holds, and a no-op `reset()` cannot put them back | +| `payments.method` | the method whose gateway the tier composes, i.e. a checkout can succeed | the tier that already has the payment adapters | the tier the payment adapters have **not moved to yet** — a phase gap, and when they move the hook appears and the case starts running with no edit to any case | + +**Optional is not a loophole.** The two gaps are real and they point in *opposite* directions — one +tier has the gateway and not the movable clock, the other the reverse — so neither gate is a tier +quietly excusing itself. Their skip counts are equal, and every other case runs on every tier +unchanged. One case is gated on **both** and so runs on neither today; it is written anyway, +because the refusal it names (a checkout against a lapsed hold) is otherwise asserted nowhere, and +it starts running the moment either tier grows the hook it lacks. + +## Classification rule + +**Transport-agnostic** (→ contract) when the assertion is about the client's *method* contract: +inputs, returned values, typed result tokens, typed rejections, idempotency replay, money as +integer minor units, snapshot semantics. **HTTP-wire-specific** (→ the transport's own file) when +it asserts request shape or method, any header (gate tokens included), base-URL joining or path +encoding, status → error mapping, retry on 5xx, `allowedHosts` egress, or a stub server's recorded +requests. Never weaken an assertion to move it; a case may **split** instead — the quote cases +assert computed totals and typed reason through `quoteCheckout` here, and only the HTTP status +stays behind. The HTTP tier's stub *server* and live service stand in for the **wire**, never for a +database (real databases, never mocks) — the wire being the one thing this contract ignores. + +**Rejections are awaited, and the code is asserted only where there is one.** Most failures here +are typed result values and are asserted as values. Where the port declares no typed result — a +malformed input — the failure is asserted as an **awaited** rejection, never a synchronous throw, so +an implementation that refuses before doing any work and one that cannot refuse before its round +trip behave alike under one case. + +That leaves **one asymmetry, recorded rather than smoothed over**: only one transport carries a +structural code with its refusal (`INVALID_INPUT` plus the field it names). The other refuses at its +wire, and its client error carries that wire's status and body and **no code at all**. So +`expectRejectedInput` asserts that both reject, and asserts the code *where a transport supplies +one* — never a status. Asserting the code unconditionally would fail a tier over the shape of its +error rather than its behaviour; asserting the status would put the wire back into the one contract +that exists to be free of it. + +**What could not be shared, and why.** Two families stayed with the in-process transport, and +neither is a case that was merely inconvenient: + +- the **cart-facing bounds** (quantity, cart-id charset) — the other transport normalizes a bad + cart value into one of the port's typed cart tokens rather than rejecting, so the same input + produces a rejection on one tier and a resolved `{ ok: false, reason }` on the other. A shared + case would have to assert one loosely enough to accept the other, which is exactly the softening + that makes an equivalence proof worthless; +- the **empty variant key** — an empty key makes the other transport build a path with an empty + segment and miss its route altogether, so a shared case would assert a route miss there and the + bound here. The shared case uses a *whitespace* key on all three writers instead, and the empty + one is asserted on the tier that checks the bound before any call; +- the **egress count** — the other transport's whole job is egress, so it has nothing to assert; + "nothing reached for `ctx.http`" is only a claim one of the two can make at all; +- the **two pinned gaps** — "checkout composes no gateway, and the refusal damages nothing" and "a + login records one challenge and dispatches no mail" — because in each the *other* transport does + the very thing this one does not, so there is no single outcome for a shared case to assert. + +**`COUPON_MAX_PER_CUSTOMER` is checkout-only and is deliberately absent from the quote cases.** The +quote path validates and never redeems, so a per-customer cap cannot surface from it; the port says +so by leaving it out of the quote's reason union and carrying it in the checkout's. It is pinned +where it belongs — in the domain's `CouponStore.redeem` result and in `CreateOrderFailure` — and the +quote cases enumerate only the four `CouponValidationFailure` reasons plus `COUPON_NOT_FOUND`. diff --git a/packages/plugin/test/contracts/commerce-client-contract.ts b/packages/plugin/test/contracts/commerce-client-contract.ts new file mode 100644 index 00000000..8c065154 --- /dev/null +++ b/packages/plugin/test/contracts/commerce-client-contract.ts @@ -0,0 +1,4002 @@ +/** + * `commerceClientContract` — the transport-agnostic client contract (work order + * 02, INC-A7 / D6 / D7 tier T5). + * + * WHAT THIS IS.

There was nothing to move, so the cases below were written + * against the tier interface from the start — which is why they cost nothing + * when the HTTP tier was deleted. + * + * PRODUCTS IS COVERED (INC-B10b-i) — all six methods: `listProducts`, + * `getProduct`, `updateProduct`, `restock`, `removeStock`, `getTaxClasses`. + * + * ORDERS IS COVERED TOO (INC-B10b-ii) — all twelve: `listOrders`, `getOrder`, + * `transitionOrder`, `resolveReconciliation`, `recordFulfillment`, + * `cancelOrder`, `getCustomerContext`, `getTimeline`, `getRefunds`, + * `refundOrder`, `listNotes`, `addNote`. The orders surface is read through + * `requireSurface`, so a tier that binds this slice without one fails by name + * rather than by running its half of the cases against nothing. + * + * WHAT THE ORDERS CASES CANNOT ARRANGE, recorded for the same reason the + * products gaps are: `arrange.order` seeds a PENDING guest order with one + * digital line, no captured payment, no shipping-address snapshot and no + * reconciliation flag — which is the state every order is born in. So a CAPTURED + * payment (and with it a non-zero refund ceiling), a flagged reconciliation, and + * a `processing` order that can legally be fulfilled are all out of reach from + * here. Each is therefore asserted in the direction this surface CAN reach — the + * refusal — and the refusals are the load-bearing half anyway: `NOT_FULFILLABLE`, + * `NOT_IN_RECONCILIATION`, and a refund that moves no money. + * + * SEARCH IS ASSERTED AT ITS FLOOR, NEVER AT A TIER'S CEILING (ADR-0019 §6). The + * shared case pins the three matches every dialect owes — an order-id PREFIX, a + * folded buyer-ref PREFIX, an EXACT folded line sku — and asserts NO negative on + * a wider one. A SQL adapter's unanchored buyer-ref SUBSTRING is a sanctioned + * superset, not a divergence to fix and not a behaviour the document store owes; + * each tier pins its own side of it in its own file, where the difference is + * visible as a difference. + * + * THE ONE REFUSAL THE TIERS SPELL DIFFERENTLY is a refund against an order that + * captured nothing. Both refuse with a 409 and both leave the ledger empty — + * that much is shared — but the REASON differs because the composition does: a + * tier with gateways composed is refused by the ceiling + * (`REFUND_EXCEEDS_CAPTURED`), and a tier with none is refused for want of a + * gateway (`REFUND_GATEWAY_UNAVAILABLE`, until INC-C1/C3 moves the payment + * adapters in-process). Rather than soften the shared case into accepting + * either, the shared case asserts what both owe and a GATED PAIR — keyed off the + * existing `payments` hook, each naming its gate in its own name — pins the + * reason on each side. The pair collapses into one case the day gateways are + * composed on both tiers. + * + * WHAT THE SHARED ARRANGE SURFACE CANNOT REACH, recorded so it is not mistaken + * for a decision: `arrange.product` goes through `upsertProductCommerce`, which + * holds the invariant "a product with a sku has an inventory row" by seeding one + * at `0`.

No published `emdash` +release carries them yet. The manifest's `emdash` specifier is the plain +registry version so that adopting a release is a one-line change, and until then +the workspace override redirecting it to the vendored build is **load-bearing**: +without it the package resolves a host that lacks the primitives, and the failure +is a type error against a real installed package rather than a missing dependency. + +## The seam + +`src/storage-access.ts` declares a **structural `StorageAccess` port**: the nine +methods the adapters use, written in terms of the host's own types via +`import type`. Nothing in `src/` imports host code at runtime — three +dependency-cruiser rules in `pnpm lint` enforce that, the react quarantine, and +the sandbox perimeter. Production injects `ctx.storage`, tests inject a real +repository; `collectionOf` is the single audited narrowing between the untyped +map and a typed collection. + +## The dialect harness + +`test/describe-each-dialect.ts` builds the port out of **real +`PluginStorageRepository` instances** on in-memory SQLite, and on Postgres when +`PG_CONNECTION_STRING` is set.

Real databases, never mocks: only Postgres can lose a race, so the +concurrency case runs there alone. + +The schema always comes from the host's `runMigrations`; never hand-create the +storage table.

It is wired as its own vitest project +(`store-emdash-d1`, `vitest.d1.config.ts`) rather than into the default battery: +it boots `workerd`, migrates a fresh database per test file, and takes a couple of +minutes. CI runs it **nightly** and on manual dispatch, never per PR. Miniflare is +given the **storefront's own** compatibility date and flags +(`sites/staging/wrangler.jsonc`), so a divergence found here means something about +production rather than about an invented runtime. + +**What the toolchain costs, stated plainly.** `@cloudflare/vitest-plugin` pins its +`wrangler` and `miniflare` versions **exactly**, and that `miniflare` in turn pins +its own `workerd` exactly. So installing it adds a third `workerd` build (~150 MB) +that only the nightly job ever executes, and **every** install — including every +per-PR CI install — pays for it. It also moves the version `sites/staging`'s +`@astrojs/cloudflare` peer-resolves `workerd` to, because pnpm picks the highest +`workerd` in the graph: the storefront build now runs the newer one. Overriding +`wrangler` back to the catalog version was tried and does **not** undo either +effect — `miniflare`'s exact `workerd` pin is what carries it — so the override is +deliberately absent rather than forgotten. The honest fix is upstream ranges or a +separate install for the nightly; until then the whole toolchain is enumerated in +`pnpm-workspace.yaml`'s `minimumReleaseAgeExclude` so nothing about it is +implicit. + +**How the tier is built.** `test/d1/describe-d1.ts` is a sibling of +`test/describe-each-dialect.ts`, not an extension of it. The split is structural: +the Node harness imports `better-sqlite3` and `pg` at module scope, and neither +exists inside `workerd`. What the two share is imported — the collection layout, +the document helpers, the fault-injection wrappers, the domain contract itself — +so only the test-surface plumbing is restated. The D1 files are named `*.spec.ts` +so the default project's `test/**/*.test.ts` glob cannot pick them up, and so +`scripts/pg-test-files.sh` never selects them. + +The dialect comes from the host's own `createDialect` reading the `DB` binding out +of `cloudflare:workers` — the same call a real site makes — which makes this the +only tier that observes the host's wiring rather than Otta's. The schema comes +from the host's full `runMigrations` set, and the suite asserts that the revision +triggers really exist on D1 and really fire for a writer that supplies no +revision. + +**What it proves.** The primitive suite (`updateIf`'s `RETURNING` and `json_set`, +`getVersioned`, `compareAndSet`'s revision assignment, `compareAndDelete`, the +query allow-list, the 100-row page ceiling) behaves on D1 exactly as it does on +better-sqlite3 and Postgres — case for case, no divergence. `inventoryStoreContract` +passes in full, with no skips — including the W1 crash-window case, which needs the +harness's `abandonPending` hook and silently asserts nothing without it. +Representative crash seams — (a), (c), (e) and the cross-SKU `commitMany` of (g) — +heal on D1 under the same real fault injection. + +**What it does NOT prove, and where that is proved instead.** Miniflare runs a +test file in one `workerd` isolate on one thread, so concurrent promises +**interleave** but no two statements execute at the same instant. The race file +therefore runs the M=5/N=50 shape as an interleaving check — strictly stronger +than the sequential contract path, strictly weaker than simultaneity. Atomicity +under genuinely simultaneous writers is the **Postgres** tier's job, and it stays +the no-oversell gate. A staging site on real D1 has many isolates at once, so the +race this tier cannot run is real in production. + +The crash tier is also not reused wholesale: the eighteen cases in +`test/inventory-crash-seams.dialects.test.ts` live inside a closure passed to +`describeEachDialect`, so running all of them on D1 means first splitting that +harness into a driver-agnostic binder plus two driver modules — a change to the +Node tiers, and its own change rather than a rider on this one. Seams (b), +(d-release), (f) and (g-`adoptMany`) are therefore Node-only today; they exercise +the same two injection mechanisms this tier already proves on D1, so what is +missing is logic coverage the Node tiers give on every commit — but it is a gap, +not a non-issue. + +## Known gap: no physical indexes + +Declared indexes reach a collection through the repository's `indexes` +constructor argument — indexes plus unique indexes, as the host composes them — +and that argument is only the **queryable-field allow-list**. The host's +index-materializing function is unexported, so neither tier creates a physical +index, and a `uniqueIndexes` declaration enforces **nothing** here. No adapter may +depend on the host to reject a duplicate: once-only has to be enforced by a +conditional write. + +## Inventory document model + +`EmdashInventoryStore` implements the domain's `InventoryStore` over **one +aggregate document per SKU, with the live holds embedded in it**, plus three +per-key claim collections. + +| Collection | Doc id | Holds | Declared indexes | +|---|---|---|---| +| `inventory` | sku | `onHand`, the live `holds` map, a bounded applied-movement ring | — (id lookup only) | +| `reservation_keys` | reserve idempotency key | the durable claim, then the terminal `ReserveResult` | — | +| `reservation_index` | reservation id | `{ sku, idempotencyKey }` plus the reservation's terminal state | — | +| `inventory_movements` | `stock:` / `adjust:` | the per-key intent, then its recorded answer | `sku`, `createdAt` | + +**Why the holds live inside the inventory document.** An inventory decrement is +not idempotent unless the row records *who applied it*. So the decrement is ONE +`compareAndSet` on `inventory/{sku}` in which the `onHand >= qty` guard (computed +in JS), the new count and the hold record all commit together — no oversell and +once-only are the same atom. + +**Reserve is a two-step, and its ONE crash window is the claim window.** The +sequence is: claim `reservation_keys/{key}` create-if-absent, carrying the sku, the +qty and the minted reservation id → the inventory `compareAndSet` → update the key +document to its terminal `ReserveResult`. The window is **claim written, +`compareAndSet` not yet run**. It is healed rather than merely tolerated: any +replayer of the key finds the `claimed` document and completes it deterministically, +reusing the **recorded** reservation id instead of minting a second one, so the +decrement happens exactly once and every caller gets the same answer. A sweeper +reaps claims that nothing ever replays. + +What the embedded aggregate removes is the SQL adapter's *second* window — a +`pending` reservation flipped to `held` separately from the decrement. The claim +window cannot be removed by any single-document primitive, because the claim and +the units necessarily live in different documents. + +**The inventory CAS step has a window of its own, and it is mitigated, not +removed.** A caller sits between reading the aggregate and committing its +`compareAndSet`; in that interval a peer completing the SAME claim can create the +hold, commit it and PRUNE it. The waking caller then sees no hold under its key and +a low `onHand` with nothing to show for it, and a *committed* prune returns no +units — so a second hold written there would be permanent, silent stock loss. The +mitigation is in the step: whenever `holds[key]` is absent, the key document is +re-read, and a terminal one ends the attempt with the recorded answer and no write. +The residual is the **one storage round trip** between that re-read and the +`compareAndSet` that follows it; removing it would need cross-document atomicity +(reading the key document and writing the aggregate in one commit), which these +primitives do not offer. INC-A3's fault-injected tier is where that round trip is +probed; a deterministic case pinning the mitigation lives in +`test/inventory-store-contract.dialects.test.ts`. + +**The outcome-before-prune ordering.** A hold is pruned on commit/release, so the +terminal `ReserveResult` is written to the key document **before** the prune, and a +replay reads that document first. Prune-first-then-crash would let a replay +conclude the key was fresh and decrement a second time. The prune is the second, +idempotent step. That *ordering* is only observable under fault injection: this +package's suites pin the consequence (a replay after a prune still answers from the +key document, and creates no second hold), and the fault-injected ordering tests +belong to the race-and-crash tier. + +**Why `reservation_index` is not optional.** Six port methods take reservation ids +with no sku, and a hold embedded per SKU cannot be found from an id alone. The +index document is written **before** the hold, so an id absent from it is *provably* +unknown — which is what lets `commitMany` throw `ReservationNotFoundError` for a +truly unknown id while `adoptMany` folds one into `lost`. Its create-if-absent +result is asserted: a colliding id is a loud `ReservationIdCollisionError`, never +silently adopted. The index also carries the reservation's **terminal** state, +because pruning a hold would otherwise erase the difference between "never existed" +and "existed and was released". + +**Cross-SKU work is not atomic.** `adopt` / `adoptMany` / `commitMany` / +`releaseAdopted` are N per-SKU writes (one `compareAndSet` per SKU, not per id), +each idempotent by reservation id, so a partially applied set is safe for any +replayer to re-run. The order-side intent record and the completing sweeper belong +to later increments. Duplicate ids in a batch are collapsed before classification. + +**Ledgers are bounded.** `adjust`, `restock` and `removeStock` keep their +once-only record in `inventory_movements` — ONE document per key, carrying the full +intent and then `applied` with the recorded result. Nothing on the hot aggregate +grows without limit: it keeps only `appliedMovements`, a ring of the last +`APPLIED_MOVEMENT_RING_SIZE` (256) applied keys with their answers, plus +`lastMovementKey` on each hold (pruned with the hold). The ring exists solely to +make the one-round-trip window between a movement's `compareAndSet` and its claim +being marked `applied` idempotent; the claim document is the durable record. + +**The residual that bound leaves, and the sweeper contract that closes it.** A +replay delayed past `APPLIED_MOVEMENT_RING_SIZE` later movements on the SAME sku +loses its witness: a stock movement would apply a second time, and an `adjust` +whose hold has also been pruned throws `ReservationNotHeldError` rather than invent +a recorded answer. Closing it needs a second atomic document, which these +primitives do not offer, so it is an accepted BOUNDED residual with a contract the +sweeper must satisfy: + +> A movement claim document in `inventory_movements` whose `applied` field is +> ABSENT — there is no `state` field; an absent `applied` IS the unfinished marker — +> and whose key still appears in the aggregate's `appliedMovements` ring, or as a +> hold's `lastMovementKey`, is given its `applied` record by the sweeper **before** +> that key can be evicted from the ring. The recorded result is the ring entry's +> `result`, or `{ ok: true, reservationId }` when the witness is a hold's +> `lastMovementKey`. The residual therefore requires at least ring-size movements on +> one SKU between a crash and the next sweep. + +**`adjust` re-derives; it never refuses.** The port takes an ABSOLUTE target, and +the SQL reference re-derives the previous qty on every retry — a lost qty CAS rolls +its claim back with the transaction — so it always applies. This adapter matches +that: a completion reads the hold's CURRENT qty and applies `toQty` against it, and +the claim's `fromQty` is the qty observed at claim time (audit, not a guard). The +only outcomes are the port's own: `ok`, a genuine `OUT_OF_STOCK` when an increase +is not backed by units, or `ReservationNotHeldError` when the hold is no longer the +caller's to move. Every caller — the claim winner and any same-key loser — derives +its answer from the DURABLE record: the claim document's recorded result, or the +aggregate's own witness promoted onto it. First writer wins and both callers return +it, so one key can never produce two answers. + +**Idempotency is always a document id.** Every claim is +`compareAndSet(id, null, …)` — a DB-level `INSERT … ON CONFLICT DO NOTHING`. No +unique index is relied on anywhere (see the known gap above). The two movement +ledgers share `inventory_movements` but never an id space, because the port scopes +keys per ledger: ids are prefixed `stock:` / `adjust:`. + +**Adopting a hold with no stamped deadline is refused.** The port states the guard +as `WHERE state='held' AND expires_at > :now`, and a SQL `NULL` never satisfies it, +so an unstamped hold is not a checkout hold. The in-memory fake treats one as +adoptable and is the outlier; reconciling the fake is a follow-up outside this +adapter. The cart stamps the deadline before checkout, so this case is "never +stamped", not "live". + +**The retry ceiling.** Read-modify-write on a hot SKU retries: bounded attempts +with full-jittered backoff, ceiling `CAS_MAX_ATTEMPTS = 12` (see `cas-retry.ts` for +why that number). Exhaustion throws `StorageContentionError` — typed, +`retryable: true`, carrying the last retryable host abort as its `cause` — and +deliberately **not** `OUT_OF_STOCK`: a shopper who could have bought must never be +told the item is gone. The HTTP/route boundary maps it to **503** and a retry; that +wiring is a later increment. The backoff `sleep` and jitter `random` are injectable +through the store's options, so a suite need not wait on real timers. + +The other typed refusal that boundary owes a mapping is +`SettingsMutationSupersededError` (see the settings section): **409**, and +**non-retryable** — re-issuing the same idempotency key can never succeed, because +the revision it is pinned to will not come back. The remedy the response should +carry is a fresh key, which is a new decision against the current state. Recorded +here as a forward note for the in-process client, alongside the 503 above. + +**No index beyond the four above.** Every access this adapter makes is by document +id, including the reservation lookups — the port has no cross-SKU listing or +expiry-scan method, so nothing here needs to query a field. The `sku`/`createdAt` +indexes on `inventory_movements` are declared for the stock-movement audit a later +increment renders, not for this store. + +## Cart document model + +`EmdashCartStore` implements the domain's `CartStore` over **one aggregate document +per cart**, plus one lookup collection the port signature forces. + +| Collection | Doc id | Holds | Declared indexes | +|---|---|---|---| +| `carts` | cart id | `state`, `orderId`, `currency`, the `lines` map keyed by sku, the embedded mutation ledger, the denormalized `holdExpiresAt` | `state`, `holdExpiresAt` | +| `cart_mutation_index` | mutation idempotency key | `{ cartId }` — a locator, never the record | — | + +**Three SQL features disappear into the shape.** `cart_lines (cart_id, sku)` UNIQUE +becomes the lines map being keyed by sku — structural, and not an index, which +matters because no tier here materializes one. The `cart_mutations` TABLE becomes +the embedded ledger, read and written in the SAME `compareAndSet` as the line it +records, so "claim the key, write the line, mark it completed" is one atom on the +cart side instead of three statements that can tear. And `reservations.expires_at +<= now` as a scan target becomes the declared `holdExpiresAt` field, because the +filter algebra has no OR and cannot reach inside a map. + +**Why there is a second collection.** `recordedMutation(key)` and +`expireHold(reservationId)` are handed an identifier with no cart id, and an +embedded map cannot be queried by its keys. `cart_mutation_index` answers "which +cart claimed this key", for exactly the reason `reservation_index` exists on the +inventory side. It is written AFTER the ledger entry, never before, so it can never +name a cart that has no record; the reverse gap is harmless, because every method +that mutates is given the cart id directly and each of them re-ensures the locator. +`expireHold` reaches a cart in two hops — `reservation_index` gives the reservation's +reserve key, which IS the add's mutation key, which the locator maps to the cart — +and that second hop is also the sweep's SCOPING: a raw reserve has no cart claim, +so no locator, so the cart sweep can never reap it. + +### The cart is the first cross-aggregate edge + +Inventory keeps every invariant it owns inside one document. The cart cannot: +`upsertLine`, `adjustLine`, `removeLine` and `expireHold` each pair a cart write +with an inventory movement across two aggregates with no transaction between them. +Every one of them is therefore written as **intent claim → inventory op → +deterministic completion**, and the bracket is visible in the code rather than +implied: + +1. `claimMutation` adds the key to the ledger with `completed: false`, + create-if-absent by the map's own compare-and-set. +2. The inventory op runs through `InventoryStore` and nothing else — idempotent on + its own terms (`reserve`/`adjust` by their key, `release` by the reservation's + state machine), which is what makes step 3 safe to reach from any interruption. +3. The line write and `completed: true` land in the SAME compare-and-set. + +Nothing here writes an inventory document. The store READS `inventory`, +`reservation_index` and `reservation_keys` — a line's live hold state and a crashed +claim's reservation id are facts about the other aggregate that the port asks this +one to report — and every WRITE goes through the injected store. + +**The attach guard is a guarded WRITE, not a read.** `CartStore.upsertLine`'s +contract makes the deadline stamp and the attach guard the same act: the SQL did +both in `UPDATE reservations SET expires_at = :deadline WHERE id = :id AND +state = 'held'`, and zero rows was `HoldExpiredError`. A *read* of the hold cannot +substitute — the sweep can reap it between the read and the cart write, and the line +would be resurrected anyway — and dropping the stamp would break checkout outright, +because `adopt`/`adoptMany` are scoped `state='held' AND expires_at > :now` and would +classify every cart hold as lost. + +`InventoryStore` declares no such method, and widening the port is a domain change +this package may not make, so the capability is adapter-local: +`HoldDeadlineStamper.stampHoldDeadline(reservationId, expiresAt)`, implemented by +`EmdashInventoryStore` as ONE guarded compare-and-set on the inventory document in +which the `state === "held"` precondition, the ownership check and the new deadline +commit together. It returns `false` — never throws — for an unknown, pruned or +adopted hold, and never touches a non-`held` one, so it can neither extend an +order's adopted deadline nor revive a reaped hold. `EmdashCartStore`'s constructor +asks for `InventoryStore & HoldDeadlineStamper`, which also keeps an adapter that +cannot supply it from being injected by mistake — and is what makes the two +tolerated `release` refusals in `expireHold` safe to recognize by TYPE, since the +errors that `release` can raise are then known rather than assumed. + +Its `expiresAt` is **non-null**, narrowed from the first cut: a stamp is always the +attach of a line to a LIVE hold, and `adopt`/`adoptMany` are scoped +`expires_at > :now`, so a hold stamped with no deadline is exactly the hold checkout +would classify as lost. The domain never asks for one either — a cart line's +`expiresAt` is null only when its `reservationId` is, and such a line never reaches a +stamp — so the type is what keeps it that way. + +It also refuses a reservation whose TERMINAL record has been written but whose hold +is not yet pruned — a state the ordered settle really passes through — so a cart can +never attach a line to units that are already spent. Same gate, same reason, as the +one `expireHold` applies before minting a fresh expiry token. + +`upsertLine` and `adjustLine` both call it INSIDE the compare-and-set step, before +the cart write (the SQL's fixed step order, reservation before line), so the guard is +re-evaluated on every attempt rather than once outside the loop. The two call sites +treat a refusal DIFFERENTLY, and the asymmetry is the port's, not a shortcut: +`upsertLine` is ATTACHING a hold to a line, so a refusal is `HoldExpiredError`; +`adjustLine`'s line already references the hold, so there is nothing to guard, +refusing the cart write would gain nothing, and `HoldExpiredError` is documented as +`upsertLine`'s failure — the update use-case calls `adjustLine` outside any catch, so +throwing there would escape unmapped whenever a checkout or the sweep took the hold +between `inventoryStore.adjust` returning and the re-stamp. The SQL's adjust stamp +was likewise unguarded. `upsertLine` additionally re-reads the claim's `abandoned` +marker on every attempt, so a reaping that lands mid-retry is still seen — and that +marker is only a fast path, which is what makes bounding the abandoned records safe: +the guarantee is the guarded stamp, which refuses the same replay one round trip +later even with the marker evicted. The regression case is in `cart-fence.dialects.test.ts`: a real `addLine`, then +`adoptMany` for an order, asserting `adopted` and not `lost` — nothing in the cart +contract or the fences would notice the stamp going missing, and only that case does. + +**The expiry choreography.** `expireHold` is the intent-claim of ADR-0019 §7.7: a +guarded flip that writes a once-only token — onto the LINE when there is one, onto +the outstanding CLAIM when the crash left none — then the release, then the removal. +The deadline is re-checked inside the flip, so a hold an active shopper reset +between listing and release is not reaped. Two rules make replay exact: + +- the token is **never cleared**; the line is deleted by the completion, so a token + on a still-present line means "an expiry was claimed and did not finish", which is + precisely what a replayer must complete; +- only the writer that **minted** the token reports the reclaim, so a lazy read + racing the sweep counts one expiry between them rather than two. + +A **fresh** token is additionally refused whenever the reservation is already +terminal. That is the obligation the inventory tier hands every reaping path: the +terminal record is written before the hold is pruned, so a `committed` reservation +can leave a hold that still looks live, and returning its spent units would be an +oversell. An **existing** token is not gated — it means the expiry is owed its +completion. + +**`adjustLine` converges, and the reconcile is a REPAIR.** The stored qty is +re-derived from the hold the store just read (ADR-0019's R5), and the hold can move +between that read and the cart write. So after the write the step goes round once +more: once the key is completed the mutation itself must never re-apply, but the +stored qty still owes the hold agreement, so a divergence is repaired IN PLACE with +the completion preserved. A bare retry could not do this — it would find `completed` +and hand back the stale line. Since a call's inventory movement always precedes its +cart write, whichever cart write lands last is followed by a pass that sees the +final hold; the loop ends the first time the two agree, inside the usual +compare-and-set budget. Pinned by `no-oversell-cart.pg.test.ts`'s convergence case, +which races two different-key adjusts on one line and asserts the pair agrees and +the units are conserved. + +**The ledger is bounded — and the bound cannot drop a crash marker.** Three classes +of record, three rules. A record that is claimed and neither completed nor abandoned +is **never** pruned at any age: it is what tells a replayer to resume and what makes +a dangling hold listable, so dropping one would orphan real stock. `completed` +records keep the last `CART_MUTATION_LEDGER_SIZE = 64`, oldest evicted. `abandoned` +records — the audit trail of a reaped crash, whose units are already back and whose +claim is retired — keep the last `CART_ABANDONED_LEDGER_SIZE = 16`, so the second +thing that could grow without limit on a long-lived cart does not. The accepted +residual is +narrow and stated in the source: a replay of a key whose completed record was +evicted no longer short-circuits, so it answers with current truth instead of the +recorded qty. It is not a double-apply — the inventory ops are idempotent by key — +and reaching it takes 64 later mutations on ONE cart between a request and its retry. + +**`holdExpiresAt` is a candidate filter, deliberately.** The SQL predicate was an OR +of a stamped-deadline arm (`expires_at <= now`) and a crashed-claim arm +(`expires_at IS NULL AND created_at <= cutoff`), against two different instants. The +filter algebra has no OR, so both fold into one indexed `<= now` and the exact +per-arm predicate is re-applied to the fetched document — an outstanding claim +contributes its `claimedAt`, which is always in the past. A cart can therefore be +listed and yield nothing, which costs a read and changes no answer. `listExpired` +pages, because the host clamps `limit` at 100. + +### Cart crash seams proven + +`test/cart-crash-seams.dialects.test.ts` opens each gap on real storage. Four of the +seven cases INJECT a fault with the shared helper — (b) through (e) let the real +writes before the gap land, throw where the process would have died, read the +documents back, and only then replay. The other three do not need to: (a) stops +after a real `claimMutation`, which IS the whole of the first step; (f) builds the +terminal-record-before-prune state with one direct conditional write; (g) asserts a +typed error rather than a crash. The file says so, rather than claiming otherwise: + +- **(a) the claim landed, the inventory movement never ran** — the record is + incomplete, no line, no stock moved; the replay resumes and decrements once. +- **(b) the reserve landed, the completion never did** — the units are gone and the + hold is live with NO line; the replay attaches the SAME hold without a second + decrement. A store that wrote the line outside the completion fails here. +- **(c) `expireHold` crashed after the once-only flip** — the token landed and + nothing else: line still there, stock still off the shelf. The replay completes it, + returns the stock exactly once, and reports `false` because it did not mint. +- **(d) `expireHold` crashed after the release** — the hardest: the stock is already + back while the line is still visible. The completion is re-runnable, the line goes, + and the stock does not come back twice. +- **(e) `checkout` crashed after the cart flip** — both fields landed together, so a + `checked_out` cart with a null order id is unreachable through the port, and the + replay is a benign `false` that never rewrites the id. +- **(f) a hold left live after its reservation went terminal** — not reaped, the + spent units stay spent, and the line survives on purpose: the per-id commit/prune + is the sweeper's, not something the cart may force. +- **(h) a settled-but-unpruned reservation** — the stamp refuses it even though the + hold still reads `held`, so no line can be attached to spent units. +- **(g) a release the cart may not perform** — a typed `ReservationNotReleasableError` + the expiry can classify, rather than a bare `Error` a caller would have to match by + message. + +## Order document model + +`EmdashOrderStore` implements the domain's `OrderStore` over **one aggregate +document per order**, plus one claim collection the idempotency key forces. + +| Collection | Doc id | Holds | Declared indexes | +|---|---|---|---| +| `orders` | order id | the header, the `readonly items` snapshot, `totals`, the ship-to, the append-only `events`, the first-wins `emailOutbox`, the `payments`/`refunds` ledgers, the three hold intents, and the denormalized `customerKey`/`buyerRefLower`/`searchKey`/`emailDueAt`/`holdsPendingAt` | `state`, `createdAt`, `customerKey`, `buyerRefLower`, `searchKey`, `emailDueAt`, `holdExpiresAt`, `holdsPendingAt`, `[state, createdAt]` | +| `order_keys` | order idempotency key | the claim (carrying the whole prepared document), then its terminal record | — | +| `payment_refs` | payment provider reference | `{ orderId }` — the GLOBAL once-only claim for a capture | — | +| `refund_keys` | refund idempotency key | the claim (carrying the whole prepared refund row), then its terminal record | — | +| `order_sku_index` | `${foldedSku}:${orderId}` | `{ sku, orderId, createdAt }` — the DERIVED pointer the search's line-sku arm reads | `[sku, createdAt]` | +| `outbox_keys` | outbox entry id | `{ orderId }` — which order document holds that email-outbox entry | — | + +**Two corrections to ADR-0019 §4, to be recorded when that ADR is next amended.** +First, `payments.provider_ref` UNIQUE was a GLOBAL constraint, and the ADR maps it +onto "the provider reference keys the entry inside `payments[]`" — a per-ORDER +dedupe. A redelivery routed at the wrong order id would be recorded twice, once per +order, and `Σ captured` is the refund ceiling; so the replacement is a claim +document, `payment_refs/{providerRef}`, and a reference already held by another +order is refused with a typed `PaymentRefConflictError` rather than recorded. +Second, per-order NOTES do not belong in this document: a note is operator-supplied +free text with no natural bound, so embedding it would make the size of the hot +money-path document a function of how much support wrote about the order. INC-B8's +`EmdashOrderNotesStore` gets a child collection instead, +`order_notes/{orderId}:{noteId}` indexed on `orderId` — its port only reads notes by +order and appends one at a time, so nothing it does needs them in the aggregate. + +**Two deviations from ADR-0019 §6, owed to the same amendment (director rulings).** §6.1 +ratified a single prefix-only `searchKey`; this adapter ships a SECOND `startsWith` arm, on +`buyerRefLower`, so the buyer-reference half of the search survives as a prefix instead of +disappearing. And §6 rejected "issue two queries and merge"; this adapter does merge arms — +upheld as exact, because the port's `OrderListCursor` is a self-describing VALUE position +rather than an opaque per-query token, so each arm can contribute its own top `limit + 1` +and the count is taken by inclusion–exclusion over the same predicate. Both are recorded +here until §6 is amended. + +**One intentional divergence from the SQL adapter's behaviour.** `markEmailSent` and +`rescheduleEmail` raise the typed, retryable `OutboxEntryUnlocatableError` for an entry id +no locator names and no bounded walk finds, where the SQL adapter's guarded `UPDATE … +WHERE id = :id` simply matches 0 rows and no-ops. The port's docstring describes the +no-op, so this is a deliberate difference and not a bug: on a document store a quiet return +there cannot be distinguished from a still-`sending` entry whose locator was lost, and that +one leaves a live lease to lapse into a double send. The port docstring will be tightened +with the ADR amendment. + +**Two methods landed early, and one whole seam did.** `recordPayment` and +`flagReconciliation` are both on `settleOrder`'s path — between the paid flip and +`commitMany`, and on every anomaly branch — so the checkout races and five +`order-flow` cases could not run without them at INC-B2. `recordPayment` is the +claim-backed append above; `flagReconciliation` is the deliberately unguarded, +last-writer-wins field write ADR-0019 §7.13 describes. For the same reason the +**email-outbox lease** (`claimNextEmail` / `markEmailSent` / `rescheduleEmail`) +landed with the refunds increment rather than with the lists: the fulfillment and +cancellation specs both assert that exactly one shipped / cancelled email DRAINS, +which runs `dispatchOrderEmails`, so the lease is a dependency of that increment's +own gate. It is R2's design — the SQL's OR-and-negation claim predicate becomes the +single denormalized `emailDueAt` index, and the claim re-applies the same predicate +to the entry it picked inside one compare-and-set — and the lease's OWN contract +cases (the crashed-dispatcher and failed-send ones) are still the list increment's. + +**The port is delivered across three increments, and the SHAPE was complete in the +first.** Creation, the guarded transitions, the audit spine, expiry and the hold +intents came first; refunds, the reconciliation resolution, fulfillment and +cancellation are described below. What remains is the lists, the search and the +customer view. Their FIELDS and their INDEXES were declared from the start — +`refunds`, `fulfillment`, `cancellation`, `reconciliationResolution`, `searchKey`, +`emailDueAt`, `customerKey` and the `[state, createdAt]` compound — so no increment +reshapes a collection that already holds live orders. Every method the last one owns +throws a typed `NotImplementedInIncrementError` naming it, and every contract case +that needs one is registered as a matching `test.todo` (see +`test/order-contract-b2.ts`, which is down to 39): a loud refusal and a visible +count, never a plausible empty answer. + +**Six SQL features disappear into the shape.** `orders.idempotency_key` UNIQUE +becomes the `order_keys` claim document. `order_items` as a child table becomes the +`readonly items` array, written only by the creating write. `order_totals.order_id` +as PRIMARY KEY becomes a field, so one totals row per order is tautological. +`order_events` becomes the embedded append-only `events`, appended in the same +write as the flip it records. `order_emails_outbox (order_id, to_state)` UNIQUE +becomes the first-wins `emailOutbox` entry. And `hold_expires_at <= now` as a scan +target becomes the declared `holdExpiresAt` index, without which `listExpirable` +could not find work at all. + +**Creation is a claim, then a create-if-absent, then a promotion — in that order.** +The claim carries the WHOLE prepared document, so a replayer finishes the create +byte for byte, reusing the recorded order id AND the minted line ids rather than +producing a second set. The promotion to `terminal` (which drops the payload) +happens LAST: a terminal key over a missing order would read as "already minted" +and lose the checkout. The one window — claim written, order document not yet +created — is healed by `createFromCart` and `getByIdempotencyKey` alike, which is +why the payload is carried at all. + +**Snapshot immutability is structural rather than a discipline.** `items` is +`readonly OrderItemDoc[]` with every element field `readonly`, and every later write +is `{ ...doc, … }` — which carries that same array by reference. There is no code +path, and cannot be one without a compile error, that rewrites a price or a title +after purchase. `order-flow.dialects.test.ts` pins both halves: a product edit after +creation leaves the line untouched, and the array is identical (element ids +included) after a flip, a payment, an intent completion and a reconciliation flag. + +**The transition is ONE write.** The guarded flip, the appended audit event and the +first-wins outbox entry are a single `compareAndSet` guarded on the revision AND on +`state === fromState` (plus, for expiry, on the deadline). So "flipped but no event" +is unreachable, the outbox once-only is per `(orderId, toState)` rather than per +event, and a lost race writes nothing at all. The SQL adapter got this from a +transaction; `order-crash-seams.dialects.test.ts` proves it here by PARKING that one +write and asserting all three facts are absent, then releasing it and asserting all +three are present — a stronger statement than aborting a transaction would be. + +### The refund lifecycle + +A refund is a claim, then ONE compare-and-set on the order document: + +1. **Claim** `refund_keys/{refundIdempotencyKey}` create-if-absent, carrying the + whole prepared ledger row — id, amount, `createdAt` — plus the order id and + whether a full refund may flip the order. +2. **Arbitrate and append** in one write on `orders/{orderId}`: the ceiling + `min(Σ captured, frozen total)` is computed from THAT document's own `payments[]` + and `totals.total`, the ACTIVE capacity `Σ refunds WHERE status != 'voided'` from + its own `refunds[]`, and the row is appended iff `activePrior + amount ≤ ceiling`. +3. **Promote** the claim to `terminal`, dropping the payload. + +**The ceiling is computed INSIDE that write, never before it.** The SQL took a row +lock on `orders` — a real `UPDATE … SET updated_at` touch, not a self-assignment — +and summed under it, so two concurrent refunds could not each read the same headroom. +Embedding both ledgers in the document makes the revision do the same job: a peer that +committed between this read and this write makes the compare-and-set lose, and the +retry re-reads the sums it must respect. A ceiling taken from a pre-read would be the +one bug this shape exists to make impossible. `refund-race.pg.test.ts` is the proof +under contention; the frozen total is read from `totals`, never recomputed from +products, which is the snapshot invariant on the money side. + +**`refund_keys` exists because the settle half of the protocol carries only the key.** +`finalizeRefund`, `voidRefund`, `markRefundUnverified` and +`getRefundByIdempotencyKey` are all key-only signatures, and an array embedded in an +order document cannot be found by a key without scanning every order. The claim is +also what replaces `refunds.idempotency_key` UNIQUE, and — as with `order_keys` — it +carries the payload so the one window is HEALED rather than tolerated: a crash between +the claim and the order write leaves a `claimed` key, and every path that meets one +re-runs the arbitration from the CARRIED intent, so the replay completes with the same +refund id instead of reserving twice. A REJECTED arbitration leaves exactly the same +state, deliberately: the SQL inserted no row when the ceiling refused a refund, so the +key stayed usable, and here the crash case and the rejection case are one code path. + +**Capacity has four states (ADR-0019 R6), and all four live in that same write.** + +| Status | Capacity | Set by | +|---|---|---| +| `recorded` | held; the only status that counts toward the `→ refunded` flip | `recordRefund` (the manual one-shot) or `finalizeRefund` | +| `reserved` | held — a slot won before the provider was called | `reserveRefund` | +| `unverified` | held, the safe direction, until a human re-checks the provider | `markRefundUnverified` | +| `voided` | RELEASED; the row stays as an audit record of the attempt | `voidRefund` | + +`finalizeRefund` is status-guarded (`reserved` or `unverified` only) and **never +re-arbitrates** — its reservation already holds the capacity, so a finalize arriving +after a concurrent void of some other row still finalizes, which is the SQL's +semantics and the port's. A stray finalize over a `voided` row is a 0-row miss that +leaves the row untouched; a re-finalize with the SAME provider reference is a benign +duplicate; a DIFFERENT reference is the loud residual the use-case surfaces. A full +refund — the FINALIZED sum reaching the ceiling — drives `→ refunded` through the same +flip transform every other state change uses, in the same write as the row, so +"refunded with no refund recorded" is unreachable. + +**Fulfillment and cancellation ride that flip, not a copy of it.** The tracking +envelope and the cancellation reason are passed to the guarded write as its +`envelope`, which is where the SQL's `extraSet` went: one guarded-flip +implementation, so a state change can never drift from the audit event and outbox +entry that accompany it. Cancellation also records the **release intent** — a +cancelled order no longer claims its holds — which the SQL adapter had no analogue +for; it is the same cross-aggregate bracket expiry uses, and `completeHoldRelease` is +guarded on `cancelled` as well as `expired`. + +### The three hold intents + +Adopting, committing and releasing an order's reservations writes N inventory +documents, and no primitive brackets them with the order write. Each is therefore +**intent → per-id idempotent write → completion**, with the intent recorded in the +order document by the same write as the state change that implies it: + +| Bracket | Intent recorded by | Per-id write | Completed by | +|---|---|---|---| +| adopt | `createFromCart`, before the use-case's `adoptMany` | `adoptMany` (idempotent per reservation id) | `completeHoldAdoption` | +| commit | the `→ paid` flip, before settle's `commitMany` | the **singular** `commit` per id | `completeHoldCommit` | +| release | the `→ expired` **and `→ cancelled`** flips | `releaseAdopted` per id, order-scoped | `completeHoldRelease` | + +**`holdsPendingAt` is how the sweeper FINDS the work.** An intent lives inside a +field, and the filter algebra can neither reach into one nor OR three together, so +the earliest `recordedAt` among the outstanding intents is denormalized onto one +declared index — the same device `carts.holdExpiresAt` is. It is recomputed from the +three intents on every write that touches one, never incremented, so it cannot drift +from what it summarizes, and it goes `null` exactly when the last intent closes. + +**Each completion is guarded on the order's STATE, and that guard is not cosmetic.** +Adoption completes only while `pending`, commit only while `paid`, release only while +`expired` or `cancelled`; on any other state the intent is closed stamp-only, with no inventory call +and nothing reported lost. The adoption case is the sharp one: after a paid order's +holds are committed and pruned, `adoptMany` over the same ids reports every one of +them `lost`, so an unguarded completion would hand a sweeper a stock anomaly that has +not happened, on the happiest possible path. `order-crash-seams` pins it from that +side — it asserts what `adoptMany` WOULD have returned, then asserts the completion +returns nothing lost. + +An intent whose `completedAt` is `null` is the marker that work is owed; each +completion is idempotent and callable by any replayer. The commit completion drives +the **singular** `commit`, not a re-run of `commitMany`, because `commitMany` skips +an already-`committed` id (ADR-0019 §2): a SKU caught between its terminal record +and its prune is finished by the singular call and by nothing else. + +**One honest consequence.** On the happy path the settle use-case runs `commitMany` +itself and never tells the order store, so `holdsCommitted` stays outstanding until +a completion pass runs. That is the sweeper's work, and it is a no-op when it +arrives — both checkout races assert exactly that: `completeHoldCommit` after a +successful settle reports `lost: []` and closes the intent. `expire` and `cancelOrder` are the two +brackets the store completes itself, because both are the store's own methods — and if +that completion FAILS after the flip is durable, the failure is swallowed: the port +documents each return as "did this call win the guarded flip", so a throw would make a +sweep that really expired the order (or a cancel that really cancelled it) look like +one that did not. The intent is left outstanding (and `holdsPendingAt` keeps it +findable), and the reason is recorded on the order's reconciliation envelope. + +**The commit completion folds two per-id errors into `lost`.** +`ReservationCommitLostError` (the hold was released or failed) and +`ReservationNotFoundError` (an id the order snapshot names and inventory has never +heard of) mean the same thing to the caller — a paid order with no hold, the +`COMMIT_LOST` anomaly. Letting the second escape would wedge the sweeper on that one +order forever and abandon the ids listed after it. + +### The admin list, the search and the keyset cursor + +This is where the document store diverges MOST from the SQL it replaces, so it is worth +stating exactly, including what an operator loses. + +**The filter algebra.** `query({ where, orderBy, limit, cursor })` supports exact match, +`null`, `in`, the four range comparisons and a prefix — joined with `AND` only. There is +**no substring, no negation and no OR**, and a `where`/`orderBy` on an undeclared field +is a runtime `StorageQueryError` rather than a slow scan. The port's `listOrders` +predicate needs an OR in two places, and each is resolved differently. + +**The search is an OR of three arms, and all three are served.** The port guarantees a +folded order-id PREFIX **or** a folded `buyer_ref` PREFIX **or** an exact folded +purchase-time line sku — the ratified narrowing (ADR-0019 §6.1), which is where the +port's contract now sits rather than at the unanchored substring it once spelled. + +| Arm | Served by | Status | +|---|---|---| +| order-id PREFIX (anchored, folded on both sides, a whole id is its own prefix, `""` matches everything) | `startsWith` on `searchKey` = `orderId.toLowerCase()` | **unchanged** | +| exact folded line sku, over the FROZEN lines, one row per order | `order_sku_index/{foldedSku}:{orderId}` — an equality on `sku`, keyset-ordered on the pointer's copy of `createdAt` | **unchanged** | +| folded `buyer_ref` **PREFIX** (anchored, a whole address is its own prefix) | `startsWith` on `buyerRefLower` | **unchanged** — this store is why the arm is anchored | + +The third row is the ratified narrowing (ADR-0019 §6.1): the filter algebra has no +substring operator, so the arm is anchored. It is a prefix rather than nothing because the +index exists anyway for the customer key, and a prefix is what the arm is FOR — an +operator types an address, or the local part of one, and finds the order. What is genuinely +lost is the MID-STRING reach: a domain (`example.com`), or any fragment that does not start +the address, returns **nothing** — not an error and not a partial answer. The screen's empty +state says so at the UI increment, and widening it back out is a `[Domain]` change with its +own PR. + +All 47 `orderStoreContract` cases run for real here, on every tier, with no copy and no +todo: the contract asserts the anchored prefix, the exact sku and the literal +metacharacters — the floor every adapter must reach — and deliberately does NOT assert +that a mid-string fragment fails, so an adapter serving the unanchored superset stays +conformant too. This store's own narrower statement, that a mid-string fragment finds +NOTHING, is pinned where it belongs: `test/order-list-cases.ts`, beside the rest of the +document model's list and search statements. + +The metacharacter guarantees survive intact: the host escapes `%`, `_` and `\` before it +builds the `LIKE`, so a prefix search is literal, and the sku arm is an equality with no +pattern language at all. + +**The sku arm cannot double-count, by construction.** Its documents are keyed by the +`(sku, orderId)` PAIR, so an order with two lines of one sku owns ONE pointer — the +port's "an order carrying two matching lines must appear once" becomes a property of the +document id rather than a de-duplication step someone can forget. `countOrders` adds the +sku set as a **set difference** (only the sku-matched orders no indexed arm already +counted, membership decided in memory from each document's own `searchKey` and +`buyerRefLower`), so a count can never disagree with the page it captions. + +**The sku arm is keyset-bounded for the LIST and `O(matches)` for the COUNT, and the +ceiling is typed.** The pointer carries the order's frozen `createdAt` and the collection +declares `[sku, createdAt]`, so the list reads pointers newest-first and opens only the +`limit + 1` orders it could return — not every order that ever bought the sku. A COUNT has +no page to stop at, so it does resolve them all: the bound is +`maxListPages × LIST_PAGE_SIZE` pointers — **1000 × 100 = 100 000** by default — past which +the call raises `ScanPageLimitError` naming `maxListPages`, never a short count. A sku with +more matching orders than that wants the budget raised, and would want a materialized +counter first. + +**The customer key stays a UNION, and it needs a second index.** ADR-0019 R3 collapsed +`customer_id = :id OR lower(buyer_ref) = :ref` into one `customerKey in [...]`, and handed +this increment the edge that narrows: an order owned by a customer id whose buyer +reference ALSO folds to the queried reference. **A contract case pins that edge** — +"listOrders customer key with a single half set filters on that half alone" requires a +`buyerRef`-only key to return the LINKED order too, whose `customerKey` holds its customer +id. So R3's conditional applies: the document carries a second declared index, +`buyerRefLower`, and the OR is resolved as **two indexed arms the adapter merges**. The +count takes them by **inclusion–exclusion** (`|C1| + |C2| − |C1 ∧ C2|`, the intersection +being one more AND clause), which is what keeps an order matching both halves counted +once. + +**The cursor: the port's value position wins, the host's opaque token is ignored.** The +host mints an opaque cursor whose seek RE-READS the cursor row by id (`select … where +id = :cursorId`), so a deleted cursor row breaks it — and ADR-0019 §6.3 left the mapping +to this increment. The decision is **option (2), re-derive**: the port's +`OrderListCursor` is a value position (`{ createdAt, id }`) that describes itself, so the +adapter seeks with a COARSE `createdAt: { lte: cursor.createdAt }` on the declared index +and applies the exact `createdAt DESC, id DESC` tie-break in memory (a true keyset +tie-break needs an OR). Two consequences, both deliberate: + +- **a deleted cursor row is not a paging fault.** The position still describes itself and + paging continues from it. That is the opposite of the host token's failure mode, and it + is the reason the mapping was chosen; `test/order-list-cases.ts` pins it, and no such + case existed anywhere in the tree before; +- **it is what makes the merge exact.** Because "strictly after this position" is + decidable for a document from ANY arm, each arm can contribute its own top `limit + 1` + rows and the top `limit + 1` of the merge is the true page. Merging arms under an + opaque per-query token could not do that, which is exactly why ADR-0019 §6 rejected it. + +**Two orderings are in play, and the invariant that reconciles them.** The adapter's total +order is `createdAt DESC, id DESC` in **code-unit** order — that is the order the port's +cursor position is defined in. The HOST's `order by` breaks its `createdAt` ties on the +storage `id` COLUMN under the **database's collation**, and Postgres's default collation is +not code-unit order: it ignores punctuation at the primary level, so ids like `oa` and `o-b` +sort one way there and the other way here. That matters only where rows are dropped, so the +rule is: **an arm is drained to the end of its boundary TIE GROUP before anything is +sliced.** Both scans keep reading past `need` until `createdAt` changes, and only then does +`listOrders` sort in code-unit order and slice. Truncating at `need` in the host's row order +would let a tied row Postgres ordered differently fall off one page without appearing on the +next — a silent gap, on one dialect only. `test/order-list-cases.ts` pins it with four +orders at one instant and ids `oa`, `o-b`, `o-c`, `o-d` paged one at a time; with the drain +removed that case fails on Postgres (dropping `oa`) and passes on SQLite, whose BINARY +collation happens to agree with code units. + +The host's `limit` clamp (50 default, 100 ceiling) is invisible to the caller: the +adapter pages at 100 internally until it has `limit + 1` rows, and a page budget +exhausted with pages still unread is a typed `ScanPageLimitError` (`maxListPages`), never +a silently short list. + +**`listForCustomer` and `linkGuestOrders`.** The first is the SQL's `customer_id = :id` +equality — not the list's union — read off `customerKey` with an in-memory re-check, and +ordered `createdAt ASC, id ASC`. The second is `lower(buyer_ref) = :folded AND +customer_id IS NULL`, collected in full and then rewritten one compare-and-set at a time, +re-applying the guard inside each write. It **rewrites `customerKey`** (R3) — without +that the customer filter would stop finding the order the moment it was linked — and +leaves `buyerRefLower` frozen alongside `buyer_ref` itself. + +**Pre-INC-B4 documents carry no `searchKey` and no `buyerRefLower`.** A `startsWith` or an +equality over SQL NULL is NULL, so such an order is unreachable by the arms that read those +fields (it is still listed, filtered, counted and paged like any other). **No backfill is +owed, because nothing is deployed** — this collection has never held a production order. +Both fields are typed `string | null` and defaulted in `normalizeOrderDoc` so the value is +DEFINED and round-trippable through a compare-and-set, not so that anyone must migrate data. +The same applies to the by-sku pointer's `createdAt`. + +### The outbox locator + +The dispatcher settles a row by ENTRY id alone, and an entry embedded in an order +document cannot be found by one. `outbox_keys/{entryId} → { orderId }` is the locator — +the same device `payment_refs` and `refund_keys` are — and it replaces the `emailDueAt` +index walk the transitions increment shipped as known debt. + +It is a **second** document, so it is bracketed rather than atomic, and the bracket has a +direction: the locator is written **after** the flip that enqueued the entry. The only +reachable tear is therefore "entry exists, locator does not", and the settle path **heals** +it — one bounded walk of the same `emailDueAt` index, then the locator is written so the next +settle is a single `get`. The reverse ordering would leave a locator pointing at an entry +that does not exist, which nothing could heal. `maxOutboxPages` bounds only that fallback. + +**An unresolvable entry id is LOUD, and that is a deliberate correction.** A claimed entry +is in the `emailDueAt` index by construction — but the index CHURNS under concurrent claims +and settles, so a walk really can pass a row another dispatcher is moving. Returning quietly +when the walk finds nothing would conflate two states that are not equivalent: an +already-drained entry HAS a locator (so it never reaches the walk, and its settle is a +guarded no-op), while an entry whose locator was lost and whose row the walk missed is still +`sending` — and a quiet return there leaves a live lease to lapse and the message to be +claimed and sent a SECOND time. So the walk is followed by one more locator read (a peer +completing the same heal is the likeliest explanation), and if that is still empty the call +raises the typed, retryable `OutboxEntryUnlocatableError`. Nothing was written, so a retry +or the next dispatcher tick is the remedy. + +**Both pointer collections read their refusals back.** `compareAndSet(id, null, …)` +returning `applied: false` means the row exists, which is the ordinary outcome of a replay +or a peer — but "idempotent" is a claim about the CONTENT, so the incumbent is read and its +`orderId` compared. A disagreement is an id collision and raises +`DerivedPointerConflictError`: adopting it would mis-route a settle onto another order's +document, or make the sku search answer with it. + +The write stays guarded on `status === "sending"`: only a CLAIMED entry is settleable, so +a double settle — or a settle of an entry nothing ever minted — is a no-op, which is what +the port's `void` return makes the correct outcome rather than a lost write. + +**The by-sku index heals the same way, in the other direction.** It is written after the +order document and **before** the key is promoted, so a crash between them leaves a +`claimed` key and any resolve of that key re-asserts the pointers; each is +create-if-absent on its pair, so the heal writes one document however many times it runs. +**The heal fires only on a key REPLAY** (anything that goes through `#resolveKey`): a +crashed create whose pointer never landed and whose key is never replayed stays a residual +for the sweeper, not something a read repairs. + +### Order crash seams proven + +`test/order-crash-seams.dialects.test.ts` opens every window on real storage. Twelve of +the fourteen cases INJECT a fault with the shared helper — the writes before the gap land +for real, the write at the gap throws or is parked, and the documents are READ BACK +before anything replays, so what the replay heals is the state the store really leaves +behind. The remaining two inject nothing and say so: they are COMPLETION-ROBUSTNESS +cases, driving a completion against a state the ordinary path reaches on its own (a +paid order, an id inventory never knew) to pin what it must NOT do. The same split the +cart section draws, for the same reason: + +- **(inject) the key claim landed, the order document did not** — the replay completes it + from the payload, with the SAME line id, and promotes the key. +- **(inject) the order document landed, the key was never promoted** — an ordinary read + heals it, and exactly one order exists for the key. +- **(inject) a partial `adoptMany` across three SKUs** — one adopted, two still held; the + completion re-adopts idempotently and closes the intent, and a second completion + is a no-op. +- **(inject ×2) a partial commit, one id terminal-committed with its hold unpruned** — the state + is READ BACK before the replay (all three reservations `committed`, two holds still + live), then the singular per-id completion finishes the set and every hold is + pruned. That last assertion is what fails if the completion ever re-ran + `commitMany`, which `continue`s an already-committed id without touching the + aggregate — leaving a live hold over spent units. +- **(completion robustness) adopt completion on a paid order** — stamp-only, + `lost: []`, stock untouched, against an `adoptMany` that would have reported every id + lost. No fault is injected: `markPaid` + `commitMany` is the ordinary path there. +- **(completion robustness) commit completion on an unknown reservation id** — folded + into `lost`, intent still closed, sweeper not wedged. Nothing is injected either: the + order is minted naming an id inventory has never heard of. +- **(inject, parked) the transition parked** — none of flip, event, outbox has landed; released, all + three have, and a lost second flip adds nothing to either array. +- **(inject ×2) expiry crashing after the flip, and after one release** — the release intent + survives, the completion returns each sku's units exactly once, and a late sweep + finds nothing owed. +- **(inject) a refund claim landed, the order write did not** — the key answers NULL (so + the use-case re-reserves rather than resuming), and that re-reserve COMPLETES the claim + with the SAME refund id; a further replay is the benign duplicate, and the ledger holds + one row throughout. +- **(inject) a reserve whose finalize crashed** — the row is still `reserved` with no + provider reference stamped, and the status-guarded replay finalizes it exactly once + (a second same-ref finalize is benign and writes nothing). +- **(inject) a void whose write crashed** — the reservation is still holding the whole + ceiling (a peer's full refund is refused), the replay wins the guarded flip, a second + void is a 0-row no-op, and a fresh refund then reclaims the released capacity. +- **(inject) a cancellation crashing after the flip** — the cancel still reports + `cancelled` (the flip is durable), the release intent is owed and findable, the + failure is on the reconciliation envelope, and the completion returns the units once. + +### Measured document size + +A three-line order with a full ship-to snapshot: **2,237 B on creation**, **4,081 B +after five transitions** (five audit events plus five outbox entries), and **5,164 B +with two captured payments and three refunds on top of those five transitions** — +measured on the sqlite tier, `JSON.stringify(doc).length`. The `order_keys` document +is **109 B** once terminal, and roughly the size of the order itself (~2.3 KB) for +the instant it is a claim carrying the payload; a `refund_keys` document is **159 B** +once terminal, and ~400 B while it is a claim carrying the prepared row. + +The 4,081 B figure is 22 B above the one the transitions alone used to cost, because +`emailDueAt` is now a populated timestamp rather than `null` once an outbox entry +exists. (Two earlier-recorded figures, 2,207 and 4,029 B, read 30 B low against this +same case on the tier it was re-measured on; the creation path has not changed.) + +All three figures are asserted, not remembered: `order-flow.dialects.test.ts` builds +that order, prints the sizes and holds them under an **8 KB cap** — unchanged, since +the busiest shape measured is still under two thirds of it — so a row-size regression +(an unbounded ledger, a re-embedded snapshot) fails a test instead of surfacing as a +slow read. + +`events` is deliberately UNBOUNDED. It is the audit spine the port promises in +chronological order, and dropping an entry would be a lie about an order's history; +the bound is the state machine itself, which admits at most nine transitions per +order, so the growth above is the whole of it (~370 B per transition, event plus +outbox entry). `payments` and `refunds` are bounded the same way — by how many times +money can move on one order (~180 B per capture, ~220 B per refund row, measured on +the case above). The one ledger with no natural bound, per-order notes, +is therefore NOT in this document at all (see the ADR corrections above). + +## Product-commerce document model + +`EmdashProductCommerceStore` implements the domain's `ProductCommerceStore` over +**one aggregate document per product, with its variants embedded in it**, plus one +claim document per live sku. It also READS and WRITES the `inventory` collection +above — the stock projections and the sku-rename carry — so a caller must bind both +layouts. + +| Collection | Doc id | Holds | Declared indexes | +|---|---|---|---| +| `product_commerce` | product id | every `ProductCommerce` field, the embedded `variants` map, the publish-gate watermark, the recorded rename carries, and the denormalized `lifecycle`/`publishKey` | `productId`, `lifecycle`, `publishKey`, `productKind`, `taxClass`, `createdAt` | +| `sku_owners` | sku | `{ ownerKind, ownerId, variantKey, live }` — the live-sku uniqueness claim | `sku` (unique; declared, **not** the enforcement) | + +**Four SQL mechanisms become document writes.** + +| The SQL | Here | +|---|---| +| `INSERT … ON CONFLICT (product_id) DO UPDATE … WHERE ` | one `compareAndSet` whose guards are computed against the value it just read | +| the compare-and-set on `updated_at` plus its zero-row classifier | the same classifier, in the same order, inside that write | +| two **partial** unique indexes (`WHERE deleted_at IS NULL`, `WHERE orphaned_at IS NULL`) plus reciprocal cross-table checks | the `sku_owners` claim, whose `live` flag IS "unique among live rows only" | +| a written-down lock order `product_commerce → inventory (sku order) → product_variants` | embedding, plus the intent-claim carry — there is no lock, so there is no order to get wrong | + +### Two deviations from the design's index table, both forced + +**`active` is filtered through a text mirror, `publishKey`.** A `where` value is bound +as a parameter and better-sqlite3 binds only numbers, strings, bigints, buffers and +null — a boolean throws `SQLite3 can only bind …` before any comparison runs.

Live-sku uniqueness is the `sku_owners` claim, reached by document id, and a variant's sku is not a field of its product document at all — an index on the product's own `sku` column would answer half the question and would be a read contract for a query never issued | +| `lifecycle` | ADDED | the tombstone axis, as three states rather than a nullable column (below) | +| `productKind` | ADDED | `ProductListFilter.productKind` is an equality the list pushes down | +| `createdAt` | ADDED | the admin list ORDERS by it, and ordering on an undeclared field throws exactly as filtering on one does | +| `productId` | ADDED | the two batch reads fetch a whole batch with one `productId in [...]` query rather than a `get` per id | + +### `lifecycle` is a three-state discriminator, and a variant may land first + +`content:afterSave` and the repeater's rows arrive as independent calls, and the port +requires a variant to land even when its product row has not. So the document is +created by whichever write arrives first and `lifecycle` says whether a PRODUCT ROW +exists: `"absent"` is a document that holds only variants, and `getByProductId` +answers `null` for it. That is also what keeps such a shell out of every list — and +why the tombstone axis is this field rather than a nullable `deletedAt`: the archive +view needs "deleted is not null", the filter algebra has no negation, and a nullable +column cannot carry the third state anyway. + +### The sku-rename carry, as an intent-claim + +`src/sku-stock-transfer.ts`. A rename moves units between two inventory documents +while the decision lives in a third, and nothing here writes two documents at once. + +1. **Decide** (`prepare`): refuse while a live hold names the source + (`SkuHeldStockError` — a read of the document the carry is about to write), then + CLAIM the target create-if-absent (`SkuStockConflictError` on a lost claim). Holding + that claim is what guarantees the move cannot be refused for occupancy later. +2. **Commit the product write**, recording the carry it owes in the SAME + `compareAndSet` — `pendingRenames`, a map keyed by the carry's token. +3. **Move** (`move`): one `compareAndSet` on the source sets `onHand → 0` and stamps + `transferOut: { token, toSku, qty }`; the target adds `qty` iff its + `appliedTransfers` ring lacks the token; the source clears the stamp; the pair of + `rename_out`/`rename_in` audit entries is written into `inventory_movements` under + `rename:`-prefixed ids that the movement claims' replay paths never address. + +**The order of 2 and 3 is load-bearing, and was learned from a failing race.** A carry +that runs BEFORE its product write can have that write lose a compare-and-set, leaving +the units under a sku the product does not hold — and while such a carry is in flight +the source reads `0`, so a concurrent writer renaming the same product carries nothing +and strands them for good. A compensating reversal does not fix it: the transient zero +is already visible to a peer that has decided how much to move. The product document's +own compare-and-set is therefore the mutual exclusion. + +**The token is DERIVED** from the write's idempotency key plus both skus, so a replay +recomputes it and adds nothing twice. A freshly minted token would make every retry a +second transfer. + +**What the lock order actually left open, corrected against the spec.** The SQL package +had NO `40P01`/`40001` retry anywhere: deadlock was avoided by acquiring the two +inventory rows in sorted sku order, and that avoidance was recorded as INCOMPLETE — the +product-side writers took a unique-index lock ahead of the inventory locks, so two +products renaming onto each other's skus could still deadlock, and a lock-order deadlock +was never mapped to a typed error. It would have reached a merchant as a 500 on a legal +edit. There is no lock here at all, so the residual goes with the mechanism rather than +being closed: the two crossing-rename cases in `variant-sku-rename-race.pg.test.ts` +assert `40P01` never surfaces, and they now pass by construction. A `40001` +serialization abort from a host above READ COMMITTED is still retried, by `cas-retry.ts`, +exactly as it is for every other document write in this package. + +### What the carry cannot make atomic, stated exactly + +- **A hold arriving between step 1 and step 3 changes the held-stock semantics, and this + is a deliberate weakening.** The SQL adapter refused ATOMICALLY: the source row was + locked before the hold count was read, so a reservation could not land inside the + window and the whole rename rolled back. Here the product write has already committed + by the time the move runs, so a hold arriving in that window leaves the rename + COMMITTED with the carry OWED. What an observer sees is a product whose sku is the new + one while its stock is still under the old one — a phantom out-of-stock on the target, + never an oversell, because no unit is ever counted twice and the source's units stay + exactly where a release of that hold expects them. It is completed by + `completeRecordedRenames(productId)`, which the sweeper runs and which ANY later write + on the product runs first, and a NEW rename of the same owner is refused with that same + `SkuHeldStockError` meanwhile. The contract pins only the SEQUENTIAL refusal, which is + unchanged and green; the window is reachable only by a concurrent reserve, and + `product-commerce-crash-seams.dialects.test.ts` drives it deliberately. +- **The SOURCE sku's claim is held until the carry is terminal.** Releasing it while the + carry is owed would leave a sku that still holds units looking free, and a first-sku + assignment ADOPTS an existing inventory document by design (THE FIRST-SKU ASYMMETRY) — + so a different owner would take those units and the eventual completion would zero them + out from under it. The claim is released only by whoever finishes the move. +- **A contended target claim.** "This owner won the sku's claim while the target had no + inventory document, and by the time the document was claimed one existed" has two + producers: a second call renaming the SAME product onto the SAME sku (legitimate) and + `seedOnHand` slipping into a one-write window (a genuine occupancy). They are + indistinguishable from the documents, so the write waits `TARGET_CLAIM_CONTENTION_ATTEMPTS` + = 6 jittered attempts — the peer case resolves within a round trip — and refuses + `SkuStockConflictError` if it does not. +- **An abandoned claim, and its inventory residue.** A call that takes a sku claim and + then never commits gives it back in a `finally`. A process that DIES in that window + cannot, and both residues are durable: a live claim nothing backs, plus — for a rename + — an empty inventory document under the target, which "occupied is occupied" would + otherwise refuse forever. So the claim is a LEASE, and a live claim held by another + owner resolves to one of four states: + + | `ClaimStatus` | Meaning | Outcome | + |---|---|---| + | `held` | the owner's live product row (or non-orphaned variant) carries this sku | `SkuConflictError` | + | `owed` | the owner no longer carries it but still OWES a stock carry away from it | refused, at any age | + | `in-flight` | nothing backs it, and it is younger than the lease | refused | + | `abandoned` | nothing backs it, nobody owes it, and it is older than the lease | taken over | + + A takeover also withdraws the empty inventory document, and only that one, which is + what `SkuOwnerDoc.createsTarget` records; a seeded empty row is never withdrawn, so + "occupied is occupied" still holds for real stock. `CLAIM_ABANDON_AFTER_MS` defaults to + 60 s and is overridable per store. + + **What a merchant sees.** Retrying a rename whose first attempt died mid-write is + refused — `SKU_TAKEN`, or `SKU_STOCK_CONFLICT` where the target already had units — + for up to the lease, and then succeeds. Nothing else is affected: a sku nobody was + half-way through claiming behaves exactly as before. +- **A writer overtaken while it was stalled.** The claim is proven when it is TAKEN, and + the product document commits later; a writer that stalls past the lease between the two + is legitimately overtaken, and its product compare-and-set — which guards the product + document's revision — can see nothing about that. So the claim is RE-ASSERTED + immediately before the commit, by a compare-and-set at the revision the call last saw: + one write that both proves the claim is still ours and restarts the lease from the + commit attempt, so a merely slow writer (a retry storm) is never reaped for being busy. + It runs on every attempt of the retry loop. A claim that has gone refuses typed and the + product document is not written. + + **The residual, stated exactly.** Two-document atomicity does not exist here, so this + closes the window down to the gap between two ADJACENT statements — the heartbeat and + the product compare-and-set — and a pause of the full lease length in that gap would + still be overtaken. It is the residual every lease scheme has. 60 s is what makes it + unreachable in practice: the whole retry budget is 24 attempts with each sleep capped at + 50 ms, under two seconds end to end, so the pause would have to be thirty times the + entire budget and land between two consecutive awaits. + + **Clock skew.** The lease compares the READER's clock against the CLAIMANT's + `claimedAt`, so workers whose clocks disagree measure different ages. The re-assertion + decides who loses, and it is always the slow WRITER rather than the data: an early + takeover moves the claim's revision, so the original writer's pre-commit + compare-and-set fails and it refuses typed instead of committing a second live row. + Skew costs a merchant a spurious retry, never a sku with two owners. + + **One residue an overtaken writer can leave.** If its empty target inventory document + had already landed before the takeover, it survives under the NEWCOMER's sku, and no + claim can withdraw it afterwards: the withdrawal is gated on the claim that created it, + and that claim is gone. Nothing is lost — the document holds no units, and it is exactly + what `seedOnHand` would have created for that sku anyway. The only visible effect is + that a THIRD writer renaming onto that sku is refused `SkuStockConflictError` on an + occupancy nobody chose, until the newcomer stocks the sku (at which point the document + is legitimately occupied) or a sweep clears it. +- **The audit trail of a swept carry.** A carry finished by + `completeRecordedRenames`/`completePendingSkuTransfer` writes NO `rename_out`/`rename_in` + pair: the entry ids derive from the write's idempotency key, which a completion does not + hold. A rename that crashed mid-flight and was finished by the sweep therefore leaves no + audit pair. That is stated rather than papered over — an entry invented by a sweeper + would claim a movement it cannot attribute. + +### `SkuConflictError` outranks both stock refusals, and is checked for BACKING + +The claim is written before the document that will hold the sku, so for one round trip +a live claim can exist that no committed row holds. Reporting "another live product +holds this sku" there would state something false about a peer holding nothing, so an +UNBACKED live claim falls through to the stock question and answers +`SkuStockConflictError` when the target already has an inventory document. A committed +claim is always backed, so the precedence the contract pins is untouched. + +### Product-commerce crash seams proven + +`test/product-commerce-crash-seams.dialects.test.ts` opens each window with the shared +fault injector, reads the documents back BEFORE replaying, and asserts conservation at +the seam as well as after it: + +- **crash after the product write, before any stock moves** — the rename is committed + and the carry recorded; the sweeper completes it, and a second run moves nothing. +- **crash after the source is zeroed and stamped** — the units are on neither count, + and the stamped quantity is what keeps the sum invariant; the replay credits the + target exactly once and clears the stamp. +- **crash after the target is credited** — the ring, not the caller, is what stops the + replay crediting 50 units instead of 25; the completion only drops the stamp. +- **a second transfer of the same token** — a no-op, which is the case that would double + the stock if the token were minted per attempt instead of derived from the command. +- **a hold landing between the decision and the stamp** — the rename commits, the source + is never zeroed so no unit is lost, the sweep reports the carry as unfinished rather + than pretending otherwise, and a new rename is refused typed until the hold clears. +- **two completions racing** — the target is credited exactly once. + +### Contention, measured + +The rename shapes are not hot-document shapes: the product document is contended only +by its own concurrent writers, and the carry's two inventory documents are contended by +a rename and whatever else touches those skus. + +| shape | max CAS attempts | +|---|---| +| product sku renames, seed and restock races (`sku-rename-race.pg.test.ts`, 8 cases) | 4 | +| variant renames and the two cross-grain rules (`variant-sku-rename-race.pg.test.ts`, 11 cases) | 2 | + +Both are reported per FILE by a final case that asserts them at or below +`CAS_MAX_ATTEMPTS` (24) and strictly above zero, so a shape that silently stopped +contending would fail rather than pass quietly. + +## Coupon document model + +`EmdashCouponStore` implements the whole `CouponStore` port. Four documents: + +| Collection | Doc id | Holds | Declared indexes | +|---|---|---|---| +| `coupons` | coupon id | the economics, the window, `usesCount`, and a best-effort `lastRedeemedKey` witness | `createdAt` | +| `coupon_codes` | folded code | `{ code, couponId }` — the code-uniqueness claim, and the only way to reach a coupon by code | — | +| `coupon_redemptions` | `${couponId}:${idempotencyKey}` | the per-key claim carrying the full intent, the bump-right `state` and its lease, then the RECORDED outcome | `couponId`, `orderId`, `createdAt`, `redemptionId`, `holdsUse` | +| `coupon_customer_caps` | `${couponId}:${customerId}` | the keys currently holding a per-customer slot | — | + +| The SQL | Here | +|---|---| +| `uses_count + 1 WHERE max_uses IS NULL OR uses_count < max_uses` | two client-side branches — a guarded `updateIf` when capped, a plain delta when not | +| `coupon_redemptions (coupon_id, idempotency_key)` UNIQUE | the document id, claimed create-if-absent | +| the insert conflict that made a second caller of one key WAIT for the winner | that document's own `state`: `claimed → bumping` is a revision compare-and-set exactly one completer wins, under a lease | +| a per-customer `COUNT(*)` taken under the coupon row's lock | the per-customer counter document, claimed BEFORE the bump | +| `ROLLBACK` undoing a per-customer refusal | an explicit, idempotent compensation | +| `uses_count - 1 WHERE uses_count > 0` | the mirror-image `updateIf` guard | +| `DELETE … WHERE NOT EXISTS (redemptions)` | a `count()` on the coupon's redemptions holding a use, read before the delete | + +### The redemption state machine + +The coupon is read first and nothing is written until it is found. Then: + +1. **claim** `coupon_redemptions/{couponId}:{key}` create-if-absent, carrying the whole + intent in state `claimed`. A claim that is already TERMINAL is the replay answer and + no counter is touched — including for a REFUSAL. +2. **claim the per-customer slot**, when the customer is identified and a cap is in + force: add this key to `coupon_customer_caps/…`. The cap is full ⇒ record + `COUPON_MAX_PER_CUSTOMER`, having consumed no global headroom at all. +3. **take the bump right**: `claimed → bumping`, a compare-and-set on the key + document's revision. Exactly one completer wins it, and only the winner reaches the + counter. A caller that loses reads the winner's answer back. +4. **re-assert the right, then bump the counter.** A compare-and-set at the revision + step 3 produced re-stamps the lease and proves the step is still ours; only then does + the guarded statement run, and it guards the cap and nothing else. +5. **record** `applied` (or `refused`, after compensating) on the key document. + +**Why step 3 exists, and why the guard carries nothing but the cap.** N callers +completing ONE idempotency key — which is what a retried checkout looks like — must add +exactly one use. Making the guarded statement itself once-only would mean pinning a +per-key witness into its `where`, which turns the delta into a revision compare-and-set: +every redemption then contends with every OTHER redemption of the same coupon, and the +retry depth grows with the CROWD rather than with the headroom (50 racers against the +24-attempt ceiling can exhaust it on a coupon with 95 uses left). Worse, it is not even +sufficient: a peer's bump overwrites the shared witness field, and a same-key replayer +that no longer sees its own key there bumps again. So once-only lives in the key +document, where it is per KEY and contends with nothing, and the counter's guard is the +invariant alone. Both halves are pinned by `coupon-no-over-redeem.pg.test.ts`: 20 +completers of one key while 20 peer keys commit, capped and uncapped. + +**The bump right is leased, because "slow" and "gone" look identical.** A step held by a +live owner and one held by a crashed owner are the same document, and a taker that +guesses wrong bumps twice. So `bumping` carries `bumpLeaseUntil` — `COUPON_BUMP_LEASE_MS`, +**10 seconds** by default, overridable per store with the `bumpLeaseMs` option — and a +waiter takes the step over only once that lapses. Until then it re-reads, and if it runs +out of patience it raises the typed retryable `StorageContentionError` so the caller's own +retry reads the recorded answer. That is the email-outbox lease (ADR-0019 R2) applied to +the same problem, and `coupon-crash-seams.dialects.test.ts` pins it from the forbidden +side: with the owner's `+1` PARKED, a second completer of the same key must refuse +retryably rather than add a use behind its back. + +**What a crashed completer costs the next caller.** A waiter is bounded by the +compare-and-set budget — about a second — so it can never outlast a ten-second lease. +While the lease still stands, a call on that key is answered `STORAGE_CONTENTION` +(retryable, nothing written); past it, the next call takes the step over and completes it. +So a crash mid-bump makes ONE key unavailable for up to the lease, with a typed retryable +answer the whole time, and the coupon itself stays fully usable by every other key. A +deployment that would rather trade a shorter unavailable window for a higher chance of +overtaking a merely slow owner can lower `bumpLeaseMs`; the counter stays exact either +way, because the lease is not what protects it. + +**The right is re-asserted, not merely taken — and that is what protects the counter.** +A lease cannot stop an owner from being descheduled past its own expiry, having its step +legitimately taken over and finished, and then waking up. So immediately before the +counter write, the owner compare-and-sets the key document at the revision it last held +(which doubles as renewing the lease). The taker's write moved that revision, so the woken +owner is refused, adds nothing, and reads the taker's recorded answer. The revision IS the +owner token: anything that writes the key document invalidates it, which is stronger than +any id the store could have minted. `a SLOW owner woken after a legitimate takeover is +fenced at its heartbeat` is that case, and a design that skipped the re-assertion fails it +at the first assertion, before the takeover even happens. + +**Clock skew, and which side loses.** `bumpLeaseUntil` is stamped from the OWNER's clock +and compared against the READER's, so a reader running ahead by more than the remaining +lease will call a live owner gone and take the step over early. With the re-assertion in +front of every counter write that is a LATENCY fault rather than a correctness one: of two +callers that both believe they own the step, whichever writes the key document first +fences the other out at its next heartbeat, so the counter still moves exactly once. The +loser is a caller — refused retryably, or reading the winner's answer — never the data. + +**The counter's attempt depth is 2, whatever the crowd.** A redemption's guarded `+1` +can be refused for exactly one reason — the coupon reached its cap — and the next read +settles that, so the step never retries more than once (plus one per concurrent RELEASE +that hands headroom back mid-flight). Capped redemptions of one coupon are therefore NOT +serialized against each other: nothing is pinned but the invariant, so nothing contends +until the invariant actually binds. + +### Coupon crash seams proven + +`test/coupon-crash-seams.dialects.test.ts`, with the shared fault injector: + +- **a PARKED guarded update** — the claim has landed and the counter has NOT moved. This + is also the proof that the helper really intercepts `updateIf`; without it every seam + below could pass while injecting nothing. +- **a LIVE owner is never overtaken** — the peer of a parked owner refuses retryably, and + the counter does not move behind the owner's back. +- **after the key-doc create, before the slot claim** — the replay takes the slot once + and bumps once; the record was still `claimed`, which provably owns nothing. +- **after the per-customer slot, before the `+1`** — the replay completes the bump and + takes no second slot: counters exact. +- **after the `+1`, before the recorded answer** — the witness survives, so the taker + recognises the bump and does not repeat it: counters exact. +- **the same, with a PEER bump overwriting the witness** — the documented residual, + asserted rather than argued: two redemptions, three uses. ONE HIGH, never low. +- **a refused `+1`** — the slot is given back and the refusal recorded, so a per-customer + rejection consumes no global headroom and a global refusal leaves no slot consumed. +- **after the refusal, BEFORE its compensation** — the replay re-runs both, and the slot + still comes back. +- **after the compensation, before the recorded answer** — the replay refuses again and + releases nothing twice. +- **two CONCURRENT replayers of a refused key** — one answer, one compensation. The loser + can take its slot AFTER the winner has compensated, which is why the compensation is + re-asserted by every caller that is told `COUPON_EXHAUSTED` rather than only by the one + that ran the refusal. +- **a SLOW owner woken after a legitimate takeover** — the lease lapses while the owner + is parked, a taker completes the redemption, and the woken owner is fenced at its + heartbeat: one use, one `applied` answer, and the owner returns the taker's redemption + id. The case also pins the ORDER — with the park held, the counter has not moved. +- **between a release's slot-free and its delete** — the replay deletes and decrements + exactly once. +- **between a release's delete and its decrement** — the second accepted residual, + asserted rather than papered over: the counter is left one HIGH, never low, and a second + release is a no-op rather than a second decrement. A release claims its decrement by + DELETING the record, which is what makes a double release impossible; the price is that + a crash in between leaves one use nobody holds. + +**The residuals are all the same residual, in the same direction.** A guarded delta in one +document cannot be made idempotent by anything written in another, so every place where a +crash can fall between the counter and its record leaves the count at most ONE HIGH per +crash. High refuses a redemption that might have fit; it never grants one that does not. +Nothing here can leave it low, which is the direction that would over-redeem. There are +three such places, and the third is worth stating precisely because it is the one the +heartbeat does NOT close: + +1. a crash after the `+1` and before the recorded answer, where a peer has overwritten the + witness — the taker re-bumps; +2. a crash between a release's delete and its decrement — the use stays counted; +3. a pause of more than a FULL LEASE between the heartbeat and the `updateIf` it fences. + The two are adjacent storage calls, so reaching this means being descheduled for ten + seconds between consecutive statements — an order of magnitude longer than the entire + call is allowed to take, since the whole retry budget is 24 sleeps of at most 50 ms. + Closing it would need the two writes to be one, which is the atomicity this store does + not have; a shorter `bumpLeaseMs` widens it and a longer one narrows it. + +Making (1) or (2) exact needs a recount of the coupon's redemption documents — a sweeper +job, and not this store's to do on a request path. + +### Four deviations from the design's index table, all forced + +ADR-0019 §4 lists `coupons` keyed by **code** with a `createdAt` index, and +`coupon_redemptions` indexed on `couponId` and `orderId`. What shipped: + +| Change | Why | +|---|---| +| `coupons` is keyed by **coupon id**, and the code becomes a claim document | `redeem`, `findById`, `update` and `delete` are all given an id, and the money path must not pay a lookup to reach the counter. The admin list is keyset-ordered on `(createdAt, id)` — which is the host's own total order only when the document id IS that id. The ADR's own `uniqueIndexes` table offers exactly this alternative for `coupons.code`: "the document id, or a claim document". The coupon's index list is unchanged at `createdAt` alone as a result, and the code search needs no index because it is a document read | +| `coupon_redemptions` adds `createdAt` | `listRedemptionsCreatedBefore` both RANGES and ORDERS on it, and ordering by an undeclared field throws exactly as filtering on one does | +| `coupon_redemptions` adds `redemptionId` | `release` is given the GENERATED id, not the document id — the port hands back an opaque id exactly as the SQL adapter did | +| `coupon_redemptions` adds `holdsUse` | a refused key keeps a document (that is what lets a replay answer the same way twice), and it must stay out of the delete guard, `releaseByOrder` and the reconciliation sweep. A boolean cannot be bound as a filter value on one dialect, so it is a STRING mirror — the same pattern as the product gate's `publishKey`, not a second invention | + +The redemption's `state` and its lease are NOT indexed: nothing queries by them, and +every reader that needs them already has the document. + +### Two accepted divergences from the SQL adapter + +Both are narrowings, both are documented rather than discovered: + +- **A refusal is recorded permanently**, so a replay of an exhausted key answers + `COUPON_EXHAUSTED` again even if headroom has since been released. The SQL adapter + rolled its refusal back and kept no record, so a retry there could later succeed. A + stable answer per idempotency key is the property the document model is built on. A + refused record is also never removed by `delete` — it holds no use, so it never forbids + one; it stays because it is that answer, and because document ids are not reused. +- **Codes are unique after case folding**, where the SQL unique index was + case-sensitive. That is the rule the admin list's case-insensitive exact search already + implies. `findByCode` stays case-SENSITIVE, by comparing the code the claim stores. + +A per-customer counter document exists only while `maxUsesPerCustomer` is in force, so +RAISING a cap from null counts only the redemptions made while a cap was set; the SQL +counted rows, which had no such window. Bounded arrays were preferred to a faithful +unbounded one here, and the alternative is a per-customer index on the redemptions. + +### Coupon contention, measured + +`test/coupon-no-over-redeem.pg.test.ts` measures the counter step (`redeem`) separately +from the bounded wait a caller spends reading a peer's answer (`redeemAwait`), because +they are different costs: one is a WRITE contending for an invariant, the other is reads. + +| shape | counter depth | wait depth | +|---|---|---| +| 50 racers on a 5-use cap (20 loops) | 2 | 1 | +| two same-customer racers on a per-customer cap of 1 (15 loops) | 2 | 1 | +| 20 racers completing ONE idempotency key | 1 | 4 | +| 20 completers of one key WHILE 20 peer keys commit, capped and uncapped | 1 | — | +| 40 racers on an UNCAPPED coupon | 1 | 1 | +| 50 racers on a coupon with 95 uses left | 1 | 1 | + +The counter step is asserted at `<= 2` — a hard bound, not a measurement — and the +overall depth against a hand-set `CAS_ATTEMPT_BUDGET` of 8, deliberately tighter than +`CAS_MAX_ATTEMPTS`, so raising the package ceiling can never turn a shape green by +accident. The last row is the one that says the depth follows the headroom and not the +crowd: 50 racers, a 24-attempt ceiling, and nobody retries at all. + +## Contention budget + +R2 has no structural fix — the aggregate is written by read-modify-write, so a hot +SKU retries — which makes the measured retry depth a **permanent** budget rather +than an interim number. `test/inventory-crash-seams.dialects.test.ts` exports +`CAS_ATTEMPT_BUDGET` and asserts it on Postgres: + +**Contention budget: measured max CAS attempts M=5/N=50 (20 loops) → 5–6, +M=1/N=100 → 2; budget asserted at 8 (< `CAS_MAX_ATTEMPTS` = 24).** + +**`CAS_MAX_ATTEMPTS` is 24, and it was 12.** The ceiling has to cover the WORSE of the +two document bounds, and the refunds increment showed that it did not. The inventory +bound is the units: at most M writes succeed before the guard turns every remaining +caller into a clean `OUT_OF_STOCK`, so depth tracks M. The ORDER-document bound is +money movements, and it is roughly `2 × (refunds that fit) + 1` — each gateway refund +writes twice (reserve, then finalize) and the ceiling-reaching one folds the +`→ refunded` flip into its second write — so a 1,000-cent ceiling refunded 100 at a +time is 21 peer writes on one document. The extra attempts only buy jittered backoff +(capped at `CAS_MAX_DELAY_MS` = 50 ms per sleep) on a path that would otherwise raise +`StorageContentionError`; no invariant depends on the number, and every per-shape +assertion bounds the measured depth AT or BELOW the constant, so raising it cannot +turn a failing shape green. The one hand-set budget, `CAS_ATTEMPT_BUDGET` = 8, is +unchanged. + +The ORDER races measure the same budget on a different shape, and one of them sits +closer to the ceiling: single-line checkout (M=5, N=40, 8 loops) → **6–7**, and +multi-line checkout (M=8/sku, N=10 carts, 3 lines, 6 loops) → **9–10** of 24. The +multi-line figure is higher because each cart contends for three aggregates at once +and its three adds race each other as well as the crowd. Both files assert only +`< CAS_MAX_ATTEMPTS`, deliberately: tightening the order races to the inventory +suite's 8 would fail on the shape that legitimately reaches 10, and loosening the +ceiling itself would hide a real regression. + +The REFUND races measure the same budget on the order document. Ten partial refunds +fitting under one ceiling (N=20 callers, 100 each against 1,000, with injected gateway +latency so the reserve and finalize legs interleave) measured a depth of **11** — under +the old ceiling of 12 by one attempt, which is what moved the constant; the +full-ceiling shapes measure 2, because a loser is refused by arbitration before it +writes anything. Every refund race now ASSERTS the depth against `CAS_MAX_ATTEMPTS` +rather than only printing it. The theoretical worst case for the gateway-partial shape +is the `2 × 10 + 1` above; an exhausted budget there is still a typed retryable refusal +and never an over-refund, because a losing writer never applies its update. + +**The embedded ledgers have a practical bound, and it is the row budget, not the +algebra.** A three-line order with a full ship-to and five transitions is 4,081 B, and +each further money entry costs ~180 B (a capture) to ~220 B (a refund row) — so roughly +**14 more ledger entries** fit on that order before the 8 KB document budget the size +test asserts. That is far beyond what the state machine and a real refund ceiling admit +on one order, which is why the ledgers are embedded and per-order notes are not. + +Both inventory figures are stable across repeated runs, and both sit at M+1: only M writes can +succeed before the guard turns every remaining caller into a clean `OUT_OF_STOCK` +with no write at all, so a writer loses at most M times. Depth tracks the UNITS on +one document, not the size of the crowd. + +The merchant shape is the exception worth naming: twenty guarded `removeStock` +calls racing twenty `reserve`s on one document — where a REFUSED removal still +writes its ledger entry, so the writes are not bounded by the units — is the one shape +that reached the old ceiling and raised `StorageContentionError`. It is also the shape +the raised ceiling most visibly served: same depth-plus-a-little, no typed failures. + +**Removal shape (20 removals racing 20 reserves on 12 units, 15 loops = 600 calls): +measured max CAS attempts 15, measured typed contention failures 0; asserted at +`<= CAS_MAX_ATTEMPTS` and `<= 90` (15% of the calls) respectively.** Both numbers moved +when the ceiling did: at 12 this shape sat AT the ceiling and raised 11–29 typed +contention failures per run, and at 24 it goes two or three attempts deeper and raises +none. That is the whole of what the extra attempts buy — callers who were being told +"too busy" are now served — and both assertions are upper bounds, so they held across +the change without being touched. + +Per-shape depth and contention, as the suite reports them per case: + +| shape | max CAS attempts | typed contention failures | +|---|---|---| +| restock same key ×24 | 2 | 0 | +| removeStock same key ×24 | 2 | 0 | +| restock +10 racing 40 reserves on 5 units | 13 | 0 | +| restock then 40 reserves on 15 units (sequenced) | 12 | 0 | +| 20 removals racing 20 reserves on 12 units | 15 | 0 | +| 10 partial refunds fitting one ceiling (N=20, gateway latency) | 11 | 0 | +| N=24 full refunds on one ceiling | 2 | 0 | +| N=30 reconciliation resolves on one flagged order | 2 | 0 | +| 40 concurrent challenge requests at a per-address cap of 3 (15 loops) | 4 | 0 | +| two concurrent crowds of 20 on two addresses, cap 3 each | 3 | 0 | +| a consume freeing one slot against a crowd of 20 (10 loops) | 2 | 0 | +| 30 concurrent registrations of one address (15 loops) | 1 | 0 | +| 12 concurrent redeems of one address, get-or-create (8 loops) | 8 | 0 | +| 24 concurrent grants of one entitlement key (12 loops) | 2 | 0 | +| 16 concurrent grants for one scope, distinct keys (10 loops) | 2 | 0 | +| 16 concurrent settings updates on one key (10 loops) | 3 | 0 | +| 10 concurrent settings updates, field-disjoint patches (8 loops) | 7 | 0 | + +The last four rows are the entitlement and settings races +(`entitlement-grant-race.pg.test.ts`, `settings-mutation-race.pg.test.ts`), and they split +the way every claim in this package does. The two grant shapes are **document-bound**: a +grant key and a scope pointer are each taken once by a create-if-absent, so a peer is +refused without contending again and the depth is the read-back, never the crowd. The two +settings shapes are not. The same-key stampede measures 3 because a caller can lose the +settings write to a peer applying the identical value and then lose the result stamp to +whoever recorded it first; the field-disjoint crowd measures 7 and is **crowd-bound**, +because distinct-key updates are last-writer-wins by port contract, so nothing refuses +anybody and a writer can lose its revision once per peer that commits ahead of it. That is +the shipping/tax rules shape, which is why the settings budget is asserted at +`CAS_MAX_ATTEMPTS` rather than under it. + +The identity races (`login-challenge-race.pg.test.ts`, +`customer-email-claim-race.pg.test.ts`) are worth reading as a pair. The +registration stampede measures **1**: the first writer takes the claim and every peer is +then refused by reading it, so nothing contends. The get-or-create measures **8**, and +that depth is not contention at all — it is the bounded WAIT a redeemer spends re-reading +until the winner's account document is readable, because the claim refuses a second +registration from the moment it is taken, which is a moment before the account behind it +exists. It is measured at N=12 and grows with how long the winner takes, not with the +crowd. + +`restock-concurrency.pg.test.ts` reports its depth and contention count **per case** +rather than per file, so a ceiling is attributed to the shape that produced it by +evidence rather than by assumption, and it asserts what survives contention: no +over-consumption, exact conservation, never negative, at least one success per loop, +the original's lower bound (successes plus retry-exhausted callers still cover the +initial units), and every ordinary loser failing cleanly. A contention failure +writes nothing, which is why conservation still pins it. The SEQUENCED restock case +is what would catch an "everything contends" regression: it has no contention to +hide behind, so its exact honour count fails if the retry loop degrades. + +## Crash seams proven + +`test/inventory-crash-seams.dialects.test.ts` opens each window on real storage +with `test/helpers/fault-injection.ts` — a wrapper that delegates every method to +the real repository and only **parks** a chosen call or **throws** on it, so the +document a replay heals is the one the host would really have left behind. Every +case reads the documents back before replaying, and every case carries the +assertion that would fail if the write order were reversed. + +- **(a) claim written, the inventory compare-and-set never ran** — the replay + completes with the id RECORDED in the claim, one hold, one decrement. +- **(b) reverse-lookup entry written, the compare-and-set never ran** — the orphan + index entry misleads no id-taking method (`commit` is the loud `COMMIT_LOST` + anomaly; `adopt`/`adoptMany`/`commitMany`/`releaseAdopted` report it lost or + no-op without throwing), and the claim still heals to the same id. +- **(c) the compare-and-set ran, the terminal answer was never written** — the + replay returns the SAME reservation id, writes no second hold, and leaves + `onHand` decremented exactly once. +- **(d) terminal answer written, the prune never ran** — a replay of the + commit/release is a no-op success that completes the prune exactly once, a + same-key reserve replay is answered from the key document, and a released hold's + units come back once and only once. +- **(e) prune-before-terminal, the FORBIDDEN order** — pinned from the other side, + because the store does not do it: the terminal write is PARKED, and while it is + parked the hold must still be live and the units still off the shelf; the prune + follows only after the release. This is the only test of the ordering rule, and + a store that pruned first would pass every replay case above and fail here. +- **(f) the movement landed, its claim was never marked applied** — restock, + removeStock and adjust each replay to the aggregate's own witness, moving + nothing twice. Past ring eviction the suite asserts the **documented, accepted + residual** rather than papering over it: a stock movement re-applies, and an + adjust whose hold is also gone throws `ReservationNotHeldError`. Both cases name + the sweeper contract above, so nobody "fixes" the test instead of the sweeper. +- **(g) a partial `commitMany` / `adoptMany` across 3 SKUs** — the first SKU + lands, the rest stay held, and a replay of the same batch completes the + unreached ones with the already-done ones idempotent. Note what the suite pins + about `commitMany`: it SKIPS an id that is already terminal, so a SKU caught + between its terminal record and its prune is completed by the singular `commit` + a replayer or the order-intent sweeper runs, not by re-running the batch. + + **The consequence, handed to INC-C4.** A batch-only replayer therefore leaves a + hold in the aggregate's `holds` map whose reservation is already `committed`. Its + units are spent, so **any future expiry or reaping path must consult + `reservation_index.terminalState` before returning units — returning a committed + hold's units to the shelf would be an oversell**, and the hold looks live to + anything that reads only the aggregate. The two obligations go together: the + sweeper drives per-id `commit` (or prune) rather than re-running the batch, and + every expiry path checks the terminal state first. +- **(h) a late same-key caller after the prune** — not duplicated here: it is the + gated mid-flight case in `test/inventory-store-contract.dialects.test.ts`, which + opens the same window with the same helper. + +## Shipping and tax rules document model + +`EmdashShippingRulesStore` and `EmdashTaxRulesStore` implement the whole +`ShippingRulesStore` and `TaxRulesStore` ports. Two aggregates, two claims: + +| Collection | Doc id | Holds | Declared indexes | +|---|---|---|---| +| `shipping_zones` | zone id | the zone's name and opaque region list, its `methods` map keyed by method id, and each method's `rates` map keyed by currency | — | +| `shipping_method_owners` | method id | `{ zoneId }` — the store-wide method-id claim, and the FAST way to reach a method from an id alone (the heal scan below is the fallback) | — | +| `tax_classes` | class id | the registry `name` (`null` when only rates live there) and the class's `rates` map keyed by rate id | — | +| `tax_rate_owners` | rate id | `{ taxClassId }` — the store-wide rate-id claim, and the FAST way to reach a rate from an id alone (the heal scan below is the fallback) | — | + +| The SQL | Here | +|---|---| +| `shipping_methods.zone_id` / `shipping_rates.method_id` foreign keys | the child IS part of the parent document, so a child with no parent is unrepresentable; a create naming a missing parent throws where the insert was refused | +| `DELETE … WHERE NOT EXISTS (children)`, twice for shipping and once for tax | the same emptiness test, read from the document the delete is guarded on and committed with `compareAndDelete` at that revision | +| `shipping_methods.id` / `tax_rates.id` PRIMARY KEY | the two claim documents, created if absent | +| `shipping_rates` PRIMARY KEY `(method_id, currency)` | the method's `rates` map key — uniqueness inside one document is structural | +| `UPDATE … WHERE amount_cents = :expected` / `WHERE rate_bps = :expected` | the same expected-value comparison inside the aggregate's compare-and-set, re-evaluated on every attempt | +| `ORDER BY id` on all four list reads | sorted in code after an unfiltered paged scan, because ordering needs a declared index and neither collection declares one | + +### Why two claim collections, where the design table names none + +**Nine** port methods take a child id with **no parent**: `getMethod`, +`updateMethod`, `deleteMethod`, `createRate`, `getRate`, `updateRate` and +`deleteRate` on the shipping side (the last four keyed by `methodId`), plus tax's +`updateRate` and `deleteRate` keyed by rate id. With the +children embedded there is no document to read for those, and a scan would answer +ambiguously the moment one child id could sit in two parents — which SQL made +impossible with a primary key and which **no declared index enforces here** (see +"Known gap: no physical indexes" above). One document answers both halves: +create-if-absent on its id IS the uniqueness enforcement, and the parent id it +carries IS the reverse lookup. It is the `reservation_index` device, for the +reason ADR-0019 gives for that one. + +An **orphaned** claim — one whose parent does not hold the child — is the crash +state, and the rule is that it misleads no reader and strands no id: every +id-taking method answers exactly as it would for an id that was never created, and +the next create of that id takes the claim over. A claim whose child really is +embedded is a collision and is loud. + +### A tax rate may exist without its class + +`tax_rates` had **no** foreign key to `tax_classes`, and the contract relies on it: +rates are created for classes nobody declared, `countRatesByClass` counts them, and +`getRate`/`listRatesForZone` return them. So `tax_classes/{classId}` is the document +that holds a class's RATES, and its `name` says whether the class was ever declared. +`null` is the undeclared case — skipped by `listClasses`, `not_found` for +`updateClass` and `deleteClass` (exactly what the missing row produced), adopted +rather than collided with by a later `createClass`, and deleted along with its last +rate so an undeclared class leaves no litter. + +### The money CAS, and the retry that must re-verify + +Both `updateRate`s guard a VALUE (`expectedAmountCents`, `expectedRateBps`), not a +version — the ABA acceptance both ports document. The value lives in a document that +also holds the parent's name and its other children, so unrelated writes contend for +one revision, and a lost revision race is retried by **re-reading and re-comparing**, +never by re-submitting the decision. A caller that lost a real edit race is therefore +told `stale` on its next attempt instead of overwriting the change it should have +seen — a wrong shipping fee or tax rate is money. + +That is pinned from both sides: `test/rules-crash-seams.dialects.test.ts` parks the +losing write while a peer commits the change, deterministically and on every dialect; +`test/rules-cas-race.pg.test.ts` drives it with a crowd, including a case whose +contending peers are renames that touch no money at all, so the retry budget is +really spent and the guard still admits exactly one editor. + +| shape (`rules-cas-race.pg.test.ts`, N=24, 12 loops) | max CAS attempts | +|---|---| +| tax `updateRate`, one rate, one expected value | 2 | +| shipping `updateRate`, one rate, one expected value | 2 | +| tax `updateRate` racing a storm of same-document renames | 6 (12 for the renames themselves) | + +The first two sit at 2 for the reason the guard exists: a loser's second attempt +re-reads a value that has moved and stops, so depth does not grow with the crowd. + +**The exception to "depth is a property of the document, not the crowd".** The three +structural edits — `updateZone`, `updateMethod`, `updateClass` — are LAST-WRITER-WINS +by port contract: they have no guard to refuse them, so every one of N writers of the +same document eventually commits, and a writer can lose its revision once per peer +that commits ahead of it. Their worst-case depth is therefore the CROWD SIZE, not a +property of the document: measured 12 at N=24 above, and past roughly N > 40 on one +document the budget runs out and the caller gets `StorageContentionError` — nothing +written, safe to retry. That is the documented shape of a rename storm on one zone or +class, not a money path: no invariant is at risk either way, and every money edit on +the same document still refuses cleanly as `stale`. + +### Rules crash seams proven + +`test/rules-crash-seams.dialects.test.ts`, over the one multi-document step each +store has: + +- **the id was claimed, the parent embed never ran** — the orphan misleads no + reader (`getMethod`/`getRate` null, the edits and deletes `not_found`, the parent + still childless and still deletable), and the replay completes it exactly once. +- **an orphaned claim is taken over** by a create in another parent, while a LIVE + child's id is never taken over — that collision is loud. +- **the child was removed, its claim was never released** — same orphan, same + answers, and the id is reusable. +- **claim-before-embed, the forbidden order** — pinned from the other side by + parking the embed: while it is parked the claim is already there and the child is + not yet readable. A store that embedded first would pass every replay case above + and fail here. +- **a money edit that loses its revision** re-reads and is refused as `stale`, + carrying the peer's value. +- **a parent delete racing a child create** refuses with the referential reason + rather than orphaning the child. +- **a release cannot take a claim a peer has adopted**: the deleter is held between + its claim read and its `compareAndDelete`, the peer adopts the id for another + parent and embeds it, and the release then refuses — the peer's claim survives and + the child is reachable by id. +- **a peer whose embed lands AFTER a release** still ends up reachable, editable and + in exactly ONE parent, and its id is refused to a second home. This is the + interleaving below. +- **a child embedded with NO claim** — the residue, constructed directly — is + rediscovered, re-claimed, and editable and deletable again. +- **`createRate` refuses a second rate for one `(method, currency)`**, the SQL + primary key's refusal, leaving the quoted price untouched. +- **a claim naming the WRONG parent is re-pointed** at the parent that really holds + the child, by the same id-keyed lookup — the heal's second branch, and the one that + keeps a partially applied takeover from making a live child unreachable. + +### The one residue, and why it is healed rather than prevented + +The create's re-assertion closes every interleaving in which a release could take a +LIVE child's claim away, bar one: a peer adopting the orphan **for the same parent**, +with the deleter's claim read landing after the peer's re-assertion and its +`compareAndDelete` landing before the peer's embed. The deleter's parent check then +sees no child (it is not embedded yet) and its revision is current, so the release +lands and the child arrives a moment later with no claim. The same state is reachable +by a crash between an embed and the next re-assertion. + +Preventing it would need a post-embed compensation — undo the embed when a +re-assertion fails — which has a crash window of its own and would leave exactly the +same residue. So it is **healed instead**: `getMethod` and the rate methods fall back +to a bounded scan when the claim does not resolve and re-establish the claim, and the +create path's collision test runs through that same lookup, so the residue can never +become one id in two parents either. The heal is automatic, not operator work, and +both halves are pinned by the two seam cases above. + +**What the fallback costs, exactly.** The scan is a paged read of the parent collection +— 100 documents a page, up to `maxListPages` (1000), with the ceiling raised as a typed +`ScanPageLimitError` rather than a short answer. + +| Call | Extra reads | +|---|---| +| any id-keyed read or write whose claim RESOLVES (`getMethod`, `getRate`, `updateRate`, `deleteRate`, `updateMethod`, `deleteMethod`) | **none** — the claim is still the fast path | +| `listZones`, `listMethods`, `listClasses`, `getRate(class, zone)`, `countRatesByClass`, `listRatesForZone` | **none** — none of them consults a claim, so the **checkout read never heals** | +| `createMethod` / `createRate` with a fresh id | one full parent scan **per compare-and-set attempt** of the claim step, because the collision test runs through the healing lookup | +| an id-keyed read or write for an id that does not exist (`getMethod("missing")`, a `not_found` update or delete) | one full parent scan per attempt, before answering `null` / `not_found` | +| an id-keyed call whose claim is missing or points at the wrong parent | one full parent scan, plus the one claim write that re-establishes it | + +Both stores are admin-surface stores over collections sized by the merchant's zone and +tax-class count, and the checkout reads are in the first two rows, which is what makes +that trade the right way round. + +## Identity document model + +`EmdashCustomerStore`, `EmdashAddressStore`, `EmdashSessionStore` and +`EmdashCredentialVerifier` implement the whole `CustomerStore`, `AddressStore`, +`SessionStore` and `CustomerCredentialVerifier` ports.

Two requests +that both read a count below the cap both insert, so the cap could be exceeded by as +many callers as arrive together. ADR-0019 §7.17 names that and refuses to let it be +inherited silently. + +The window is a claim document instead, and the state machine is small: + +``` +admit : read the claim → drop lapsed slots → refuse if the rest fill the cap + → compare-and-set the value it counted, with this slot added +write : create-if-absent the challenge the slot names +consume : compare-and-set the challenge (revision + consumedAt absent) +release : remove this slot at the revision read AFTER the consume committed, + deleting the document when it empties +``` + +Of N concurrent admissions exactly one wins each revision, so the cap is **exact**, +not approximate — 40 concurrent requests at a cap of 3 admit 3, and a freed slot is +worth exactly one more admission and never two (`login-challenge-race.pg.test.ts`, +measured depth 4). A refusal writes nothing at all: the response is identical to the +success case either way, which is the port's own rule about throttling not becoming an +enumeration oracle. + +Every residual points the same way, which is the direction ADR-0019's rule (c) +requires: + +| Crash | Residue | Cost | Heals by | +|---|---|---|---| +| after the admission, before the challenge write | a slot naming a challenge nobody can redeem | one admission refused | the slot's own expiry | +| after the consume, before the release | a slot for a spent challenge | one admission refused | the slot's own expiry | +| the compensating release itself is lost | as above | one admission refused | the slot's own expiry | + +No sweeper is required, because every slot carries the expiry of the challenge it +names and the next admission drops it. That is also the one place the window is +pruned: a refusal does not write. + +**Two deliberate swallows, and only two.** `releaseChallengeSlot` and the email claim's +compensating release (`createCustomer.release`) do not propagate +`StorageContentionError`. It runs only after the write it compensates for has already +been decided, so raising would turn a login that has already succeeded into an error +the user cannot retry — the challenge is spent, so the replay answers `CONSUMED` — in +exchange for freeing a slot a moment earlier. Not raising leaves an over-refusal that +expires by itself. The email release is the same trade on the same shape: it runs inside +`create`'s catch, on a path that is already failing, and raising there would REPLACE the +failure the caller has to see with one about the compensation — while an unreleased claim +is just an orphan the abandon window heals. Every other contention failure in this +package propagates. + +### The email claim needs an abandon window, and the race proved it + +The claim is taken before the account document is written and re-asserted immediately +before that write (rule (a)). That is not sufficient on its own: a peer that read the +claim between the re-assertion and the account write saw a claim with no account +behind it, called it orphaned, took it over — and both callers then wrote an account +under one address. The first run of `customer-email-claim-race.pg.test.ts` found +exactly that. + +So the claim carries `claimedAt` and a `CLAIM_ABANDON_AFTER_MS` window (60 s, option +`claimAbandonAfterMs`), for the reason the sku claim carries one: **a holder a moment +from writing and a holder that is gone are the same document.** A claim no account +holds is taken over only once it is older than the window; until then the address is +refused as a duplicate — which is what it is about to become, and which for a genuinely +crashed holder is an over-refusal bounded by one window rather than a duplicate account +that is forever. + +**The re-assertion is a heartbeat, so the lease renews.** Every attempt stamps a fresh +`claimedAt` alongside the revision it re-asserts, exactly as the sku claim and the coupon +bump right do. A registrant that is slow but alive — retrying inside the compare-and-set +budget — therefore keeps its lease however long the retries take, and only one that +stopped writing lets the window lapse. A fixed deadline stamped at the first claim would +have made the window a timeout on the whole call instead. + +**The fence, and what clock skew costs.** Renewal is half of it; the other half is that a +holder which DID lapse must not commit the work it no longer has the right to do. That is +the re-assertion's other job: it is pinned to the revision the takeover replaced, so a +registrant parked past its window wakes to a refused re-assertion and returns +`DuplicateCustomerEmailError` with no account written — pinned by "a registrant parked +past the abandon window is fenced out by its own re-assertion", on all three tiers, and +that case fails if the refusal is removed. The window is stamped from the holder's clock +and read against the taker's, so a reader a full window ahead can call a live claim +abandoned and take it over: the holder's next re-assertion then refuses, which is the +fence working rather than failing. Skew costs a spurious refusal for the slow or skewed +registrant, never a second account, and no invariant depends on the two clocks agreeing. + +One caller feels that refusal legitimately: the verifier's get-or-create behind a +redeem. The claim refuses a second registration from the moment it is taken, which is +a moment before the account behind it is readable, so a single re-read after the +duplicate could find nothing and report a duplicate for an address the caller was +logging into. Its re-read is therefore **inside** the bounded retry, and only an +exhausted budget is reported — as the typed retryable contention failure, never as a +duplicate (measured depth 8 at N=12, which is the wait, not contention). + +### The claim is the fast path; the email lookup heals + +`getByEmail` follows the claim, and when it does not resolve it queries the declared +`emailLower` index, takes the lowest customer id deterministically, and re-establishes +the claim. So the read **may write**, and it may raise `ScanPageLimitError` where the +SQL could only answer `null` — both the price of never leaving a registered account +unreachable by its own address. The cost is asymmetric on purpose: + +| Call | Extra reads | +|---|---| +| `getByEmail` whose claim RESOLVES | **none** — one claim read plus the document | +| `get`, `update`, and every address and session method | **none** — none of them consults a claim | +| `create` | one lookup per compare-and-set attempt of the claim step, because the collision test runs through the healing lookup | +| `getByEmail` for an address nobody holds | one bounded indexed query, before answering `null` | +| `getByEmail` whose claim is missing or stale | one bounded indexed query, plus the one claim write that re-establishes it | + +### A customer document can exist without a customer + +`addresses` had no foreign key to `customers`, and the address-book contract relies on +it: a book is written for a customer id nobody registered. So `email` is what says +whether an account was ever created. `null` is the undeclared case — `get`, +`getByEmail` and `update` answer for it exactly as the missing row did, a later +`create` for that id **adopts** it rather than colliding (its addresses are that +customer's), and it is deleted along with its last address so an address-only document +leaves no litter. It is the device the tax store uses for a rate whose class nobody +declared, and for the same reason. + +### Nothing stores a token + +`create` mints an opaque session token, returns it once and persists only its SHA-256. +The challenge stores only the hash of the token it emailed. Both hashes come from +WebCrypto off `globalThis` — never `node:crypto`, which does not exist in the sandbox — +and the challenge's comparison is a hand-written constant-time one, because +`timingSafeEqual` does not exist there either. A session is reachable by exactly two +routes: the hash of a token somebody holds, or the `customerId` index the port's own +history read requires. `SessionSummary` carries a separate `sessionId`, so no +credential material has a path onto an admin surface even by accident. + +### Identity crash seams proven + +`test/identity-crash-seams.dialects.test.ts`, both Node dialects, each reading the +residue back before proving what a later caller sees: + +| Seam | Residue | What a later caller gets | +|---|---|---| +| claim taken, account write lost | none — the compensating release gives the address back | the address registers cleanly | +| claim taken, account write **and** release lost | an orphan claim | refused for one abandon window, then taken over; no account is ever visible under the address meanwhile | +| an account whose claim was deleted | none, after the next lookup | the account is found by address and the claim is written back | +| slot taken, challenge write lost | none — the slot goes back | the full window is admittable | +| slot taken, challenge write **and** release lost | a held slot | one admission fewer until the slot's expiry | +| consume committed, release lost | a held slot for a spent challenge | the replay is `CONSUMED`; the window resets at the expiry | +| an address update that loses its revision to a concurrent delete | none | the retry re-checks ownership and answers the miss rather than resurrecting the address | +| a registrant parked past its lease, overtaken by a peer | none | its own re-assertion refuses before any account write: one account owns the address, and it is the peer's | +| consume committed and slot released, then `#resolveCustomer` exhausts its budget | a spent challenge with no account resolved | the caller sees the typed retryable failure and the link cannot be replayed (`CONSUMED`) — one lost login, never a second redemption. Not enumerated in the suite: it needs a contention storm on a document only one caller writes | + +### What the identity tier does NOT carry + +- **No email change and no customer delete.** `UpdateCustomerInput` patches + `displayName` and `emailVerifiedAt` only, and there is no delete on either port. So + the release ordering has exactly one site — the compensating release when an account + write did not land — and the "un-embed, then release at a post-write revision" rule + has nothing else to guard here. +- **No sweeper.** Both claims heal in path: the email claim by the lookup's fallback, + the throttle by the expiry every slot carries. + +## Entitlement, payment-event, settings and order-note document models + +The four smallest ports in the commerce layer, and the only tier where two of the four +stores write exactly one document per call. Seven collections: + +| Collection | Doc id | What it is | +|---|---|---| +| `entitlements` | grant idempotency key | one grant; the key IS the once-only | +| `entitlement_lookups` | `order:{orderId}:{sku}` / `buyer:{foldedRef}:{sku}` | a pointer from one authorization scope to the grant that satisfies it | +| `payment_events` | dedupe key | the received-events audit row | +| `payment_anomalies` | a digest of the anomaly's own fields | one alert-worthy settlement anomaly | +| `settings` | `store` | the operational settings singleton | +| `settings_mutations` | mutation idempotency key | one mutation's intent, and — once — its result | +| `order_notes` | note idempotency key | one append-only merchant annotation | + +Declared indexes: `entitlements` declares `orderId`, `buyerRefLower`, `sku` and `state`; +`order_notes` declares `orderId`; the other four declare nothing, because nothing +queries them. + +### The delivery gate, and why its pointer is a cache + +`check` is the file-serving gate: no active grant, no download. The SQL served it with +two composite indices — `(order_id, sku, state)` and `(lower(buyer_ref), sku, state)` — +behind the predicate +`state = 'active' AND sku = ? AND (order_id = ?)? AND (lower(buyer_ref) = ?)?`. Here the +filter algebra is AND-only over single declared fields, so the composite becomes a +conjunction of four declarations, and `state` is declared rather than filtered in code +for a specific reason: a page of revoked grants must not be able to hide an active one +behind the limit. + +That query alone is correct and indexed. The `entitlement_lookups` pointer sits in front +of it so the hot single-scope path pays two keyed reads instead of an index scan — and it +is therefore a **cache, never authority** (ADR-0019 rule (b)). Three consequences, all +deliberate: + +- A pointer is re-validated against the grant it names. A pointer whose grant is + revoked, missing, or disagrees about the scope or the sku authorizes nothing. +- When a pointer does not resolve, the gate queries and writes the pointer back, so + `check` is a read that may WRITE. That is the one mechanism healing both a crash + between the grant and its pointers and a pointer left on a revoked grant. Its cost is + one indexed page of one row, on the reads that miss only. +- **Revocation needs no pointer maintenance**, which is why the store has no revoke + method to keep in step with one. + +The operator-authenticated shape — an order id AND a buyer reference — has no pointer of +its own and goes straight to the query. A third key space for a conjunction no hot path +takes would be cost without a read to serve. + +**What a stale pointer costs, exactly.** A scope whose named grant has been revoked and +then re-granted under a new key pays, per `check`, until the first one heals it: the +pointer read, the named grant's read, and one indexed query of one row — three reads +rather than two, plus one pointer write on the read that heals. `#claimLookup` on the new +grant does NOT displace the stale pointer (an existing pointer is left alone, which is +what makes one scope's pointer deterministic under concurrent grants), so the re-grant +itself does not clear it; the next `check` does. That is the asymmetry rule (b) describes: +a scope whose pointer resolves pays nothing extra, and the one that does not pays a +bounded, self-clearing surcharge. + +### The scope id is an authorization key, so its parts are escaped + +A scope is a pair, and joining two arbitrary strings with a separator is ambiguous: +`("ord-a", "B:C")` and `("ord-a:B", "C")` collide under a raw join, and one document +authorizing the other's delivery is a security bug rather than a collision statistic. +Both value parts are percent-escaped before they are joined — `%` first, so escaping the +escape cannot collapse two encodings onto one — and a case drives the collision end to +end. + +### A scopeless check is refused, not answered `false` + +The SQL short-circuited a query with neither scope to `false`; so did the in-memory fake. +Here it raises `EntitlementScopeRequiredError`, and that is a deliberate divergence in +loudness (never in outcome — both are fail-closed, and nothing is served either way). The +port's type requires a sku and makes both scopes optional, so a scopeless query is not a +condition a storefront produces: it is a caller that lost its session or its order id +somewhere above and is about to serve a file on the strength of a sku alone. `false` +hides that as a refused download; the typed error names it. + +### Payment events: two collections, because a document id cannot be null + +The SQL kept deliveries and anomalies in one table separated by a nullable UNIQUE column +— a delivery row carried a `dedupe_key`, an anomaly row carried a `kind` and a NULL key, +and the nullable UNIQUE is what let many anomalies coexist while a real dedupe key +collided. A document id cannot be null, so the two shapes become two collections, which +states the separation in the schema rather than in a convention about which columns are +set. + +Two divergences worth naming: + +- **A dedupe key redelivered against a DIFFERENT order still answers `false`.** Faithful: + the SQL's UNIQUE was global and its conflict clause silent. The loud cross-order guard + is the order store's `payment_refs/{providerRef}` claim, because that is the write that + moves the captured total and therefore the refund ceiling. This store holds no order + pointer of its own and deliberately duplicates none. +- **`recordAnomaly` is genuinely idempotent, where the SQL was not.** The document id is + a SHA-256 of the anomaly's five fields, so a replay producing the identical anomaly + records it once; the SQL minted a fresh row id per call and wrote a second + indistinguishable row. Anything that differs — including the instant — is its own + document, and nothing is ever swallowed. + +**`payment_anomalies` is write-only and unindexed, so it grows without a reader or a +prune** — an operator surface that lists and retires anomalies is owed, and it is what +will decide the collection's indexes. + +### Settings: the claim carries the intent and the revision it was decided against + +The SQL did the whole of `update` inside one transaction: read current, merge, claim the +key with the merged values, and — as the claim's winner only — upsert the row. Without a +transaction the steps become: + +``` +claim : settings_mutations/{key} create-if-absent, carrying the PATCH and the settings + revision the creator just read — both written once, never rewritten +apply : merge the patch over the current settings, compare-and-set — the CREATOR at the + revision it just read, anyone else at `decidedRevision` or not at all +record : the claim's `result`, assigned EXACTLY ONCE, after that write committed +``` + +**The claim cannot carry a pre-computed result.** The SQL's ledger row could store the +merged values at claim time because the claim and the upsert were one transaction, so +"claimed" and "applied" were the same instant. Split across two documents they are not, +and a result recorded before the write is PROVISIONAL: if a peer moves the settings the +mutation has to be re-decided against a newer base, and anything that read the +provisional value holds an answer no state ever had — including a concurrent caller of +the same key, which is how two callers of one key end up disagreeing. + +So the two halves are explicit. A claim with `result: null` means DECIDED; a claim with a +result means LANDED, and that result is single-assignment — written after the settings +write, guarded on the claim revision that still had `result: null`. Of any number of +callers of one key, the first to record decides the answer and every other one reads it. + +**And a DECIDED claim is pinned to the revision it was decided against**, which is what +makes the crash case safe rather than merely completable. Four consequences: + +- **A replay of a landed mutation writes nothing**, so a stale replay arriving after a + newer update returns what its mutation applied and cannot clobber the newer value. The + document-model suite pins that on the two documents' revisions rather than on their + values. +- **A caller that did NOT create the claim may apply it only at `decidedRevision`.** Past + that revision the patch was computed against a state that no longer exists, so applying + it would overwrite whatever replaced that state — the clobber the port forbids. It is + refused instead, with a non-retryable `SettingsMutationSupersededError` carrying the key + and both revisions, and nothing is written. The remedy is a fresh idempotency key, which + is a new decision against the current state. Merging cannot revert a field the patch + OMITS, because an omitted field is read from the base — but it says nothing at all about + the fields the patch NAMES, which is exactly what the pin is for. +- **A non-creator completion can therefore succeed at most once, ever**, because applying + it moves the revision it was pinned to. The patch can never be applied twice. +- **The creator keeps re-merging over the new base**, because its intent is live — it is + the call the operator is waiting on, not a replay of a decision made earlier. That is + why distinct-key updates never lose each other's fields, which the race drives with + field-disjoint patches, where a lost update would be visible as a field reverting to its + domain default. + +**A merge that changes nothing writes nothing.** If the patch's effect is already present +in the document that was read, the mutation is recorded against the value that is there +and no settings write is issued. It cannot mask a clobber — a no-op write clobbers nothing +— and it does two useful things. It lets a mutation whose own write landed but whose stamp +was lost be completed rather than refused; and it keeps a same-key stampede from refusing +everybody but the creator, because every caller of one key merges the same patch to the +same value, so the peers find the effect already present rather than a moved revision. + +A claim is a once-only record rather than a lease, which is why ADR-0019 rule (a) does +not bind it: nobody can take it over, so there is no owner token to re-assert. The guard +on the only value-bearing write is a revision read and used in the same attempt. + +### Order notes: keyed by the idempotency key, in a child collection + +`order-documents.ts` records why notes are not embedded in the order aggregate: a note is +operator-supplied free text with no natural bound, so embedding it would make the size of +the hot money-path document a function of how much support wrote about it. + +The document id is the note's **idempotency key**, not a `{orderId}:{noteId}` composite +as ADR-0019 §4 first had it (the table now carries the corrected form). Three reasons: the +SQL's once-only was `order_notes.idempotency_key` UNIQUE, table-wide; ADR-0019's own +mapping says that constraint "becomes the document id of its claim"; and a composite id +would need a second claim document plus a crash seam between the two to buy nothing, +since no caller holds a note id. Keying on `{orderId}:{noteId}` alone would have been +worse than either — it would make one idempotency key admissible once PER ORDER, which is +weaker than the constraint it replaces, and a case pins the cross-order behaviour. + +`listForOrder` pages the declared `orderId` index at 100 and applies +`createdAt ASC, id ASC` in code: the pair has to be sorted together or the tie-break is +not a tie-break, and a note id means nothing to a reader on its own. `createdAt` is +fixed-width ISO-8601, so the comparison is dialect-identical. A list that exhausts its +page budget raises `ScanPageLimitError` rather than truncating, because a short note list +reads as "nobody wrote that". Three cases cover it: a multi-page read, a multi-page read +where every note shares one instant so the tie-break carries the whole ordering across the +cursor, and the ceiling. + +### Crash seams proven in this tier + +Two of the four stores have a multi-document step, so two have a seam. +`test/misc-crash-seams.dialects.test.ts` (both Node dialects) and +`test/d1/misc-crash-seams.d1.spec.ts` drive each from the forbidden side, in BOTH +injection modes: `"instead"` asks what a missing write leaves behind, `"after"` asks what +a caller who believed it FAILED is told when it retries over a write that really landed. +The second is the shape a retrying webhook, a double-clicked Save and a resubmitted note +all take. + +| Crash | Residue | Cost | Heals by | +|---|---|---|---| +| after the grant, before either pointer | a grant no scope points at | one indexed query per missing scope, once | the next `check` on that scope, or a replayed grant | +| after the first pointer, before the second | one scope pointed, one not | as above, for that scope | as above | +| after the mutation claim, before the settings write | a decision with no outcome | the update applies later, or is refused as superseded if something moved the settings first | the next call with that key, at `decidedRevision` only | +| after the settings write, before the result stamp | an applied value with no recorded result | nothing: the completion's merge changes nothing, so it records without writing | the next call with that key | +| the retry budget runs out after the claim was created | as the first settings row | **the update applies LATER, not never** — or not at all, if it is overtaken first | as above | +| a creator lands while a concurrent replay of its key concludes "superseded" | none — the value is applied and stamped | the replay's caller is refused for an update that did land | nothing to heal: re-reading the claim returns the landed result | + +Two of those rows are worth reading twice. The budget row is the one residual in this tier +that does not resolve toward over-refusal, so it is named rather than filed under rule (c): +`StorageContentionError` from a settings update whose claim already exists means the +operator's change is decided and unlanded, and the next call with that key lands it — at +`decidedRevision`, or not at all if something has moved the settings since. The error is +retryable and nothing is lost, but the honest statement is "applies later" rather than "was +refused", and a caller that never retries leaves the claim for whoever does. No other step +here has that shape: a grant's budget running out after the grant document landed leaves +the grant authoritative, and both single-document stores write nothing at all. + +The last row is the accepted residual of the pin itself. A creator may land its value while +a concurrent replay of the same key, reading a revision the creator's own write has just +moved, concludes "superseded": the value was applied and the replay's caller was refused. +That is over-refusal — never a double apply, never a clobber — and it is the direction this +tier resolves every residual in. + +`order_notes` and `payment_events` write one document each, so a lost write leaves NOTHING +and the retry is a clean first attempt rather than a repair — which two `"instead"` cases +assert, since "there is no seam" is a claim that needs evidence too. Their `"after"` twins +assert the other side: a note that landed is returned to its retry as `appended: false`, +and a dedupe row that landed makes the retry a redelivery. + +### What this tier does NOT carry + +- **No revocation path.** The `EntitlementStore` port has `grant` and `check` and nothing + else, so the contract's revoke hook is implemented in the test harness as the + compare-and-set equivalent of the SQL harness's `UPDATE`. It is deliberately not test + surface on the production store: a revocation path with no caller belongs on the port + when one arrives. +- **No settings validation.** The port's `update` is a *validated* partial update and the + domain's `updateSettings` use-case is what validates it. A store that re-validated + would be a second, drifting copy of a rule the domain owns — and the SQL adapter + validates nothing either. +- **No anomaly read surface.** See the forward reference above: anomalies are written to + be alerted on, nothing reads them back, and the prune that will need indexes is owed. + +## Reporting rollup document model + +Reporting is the one port whose SQL was pure read-time aggregation — one `GROUP BY` over +`orders` joined to `order_totals`, `order_items` and `refunds`, with the period bucket as +a dialect-branched truncation. There is no join, no aggregate and no raw SQL here, so two +of the four reports moved to write time and two did not: + +| Report | Where it is computed | +|---|---| +| `revenueByPeriod` | `reporting_daily`, paged by the `date` range, folded to day / week / month | +| `ordersByStatus` | the same scan, folded over `stateCounts` | +| `topProducts` | on read — a scan of `orders` over the FROZEN line snapshots | +| `lowStock` | on read — a scan of `inventory`, titled through the live sku claim | + +| Document | Contents | +|---|---| +| `reporting_daily/{currency}:{YYYY-MM-DD}` | the orders CREATED that UTC day in that currency: `stateCounts`, `revenueOrders`, `revenueCents`, `refundEntries`, `refundedCents` | +| `reporting_applied/{orderId}:{from}>{to}` · `{orderId}:refund:{refundId}` | one rollup event, claimed — and, once a recompute has counted it absolutely, `absorbedAt`. Indexed by `date` (how a recompute pages a day's claims) and `orderId` (the diagnostic axis) | + +**The day is the grain, and the other two intervals are folds over it.** A week is the +seven day documents from its ISO Monday and a month is its own days, so nothing is keyed +by a week or a month and no second aggregate can disagree with the first. That is only +sound because every boundary is UTC and every coarser bucket is a union of whole UTC +days — which is exactly what `date_trunc(…, AT TIME ZONE 'UTC')` and `strftime(…)` +computed, so the fold and the statement agree by construction rather than by testing. + +**The bucket is the order's CREATION day, never the day anything happened to it.** A +transition on an order placed three months ago moves three-month-old counters, and a +refund issued today lands in the day the order was placed. Both follow from the port: +revenue is bucketed on `orders.created_at` and counts only orders whose CURRENT state is +in the allow-list, and a bucket's `refundedCents` answers "what did the orders placed in +this period give back", which is the only reading under which the two figures in one row +are comparable. + +**A transition is a MOVE, and revenue moves with it.** `ordersByStatus` needs every state, +including the excluded ones, so the state the order leaves is decremented and the state it +enters is incremented. The revenue figure cannot be derived from those counts — it sums +totals rather than counting orders — so the event carries the order's net total and +revenue enters or leaves according to the allow-list. A refund is not a transition and is +not driven by one: it adds to the day's returned money whatever the order's state is, +which is what keeps a fully refunded order's money reportable. + +**`revenueOrders` and `refundEntries` are not decoration.** They are how a bucket's +EXISTENCE is decided: the SQL emitted a row as soon as either half contributed, so a +genuinely zero-total order in a revenue-counting state is a row at `revenueCents: 0` and +not an absence. Counting the contributors rather than testing the sums is the only way to +tell those two apart. **The money is part of the test as well**, though: a bucket is +reported when either counter is above zero OR either sum is non-zero, because a counter +that drift has taken to zero over a non-zero sum is a day that is holding money, and +dropping it would hide exactly the figure a merchant would come looking for. + +**Flooring is announced, because it is proof of drift.** A decrement that would take a +counter below zero is clamped — no report should be able to show negative revenue — and +`EmdashReportingStoreOptions.onAnomaly` is called with the counter, the day document, the +order and the two numbers. An operator seeing one should run a recompute over that day. +The flag deliberately does NOT live on the document: a recompute would erase it in the +same write that fixes the day, so the record of the drift would disappear with the drift +itself, whereas the observer has already reached the log. + +### The claim is written first, and the residue is an under-count + +One event is two documents and there is no transaction between them: + +``` +claim reporting_applied/{claim} create-if-absent — the once-only gate +counters reporting_daily/{currency}:{day} compare-and-set — the value +stamp the claim's `appliedAt`, best-effort, as a DIAGNOSTIC +``` + +A crash between the first two leaves the event spent and the counters short: the report +says less money than came in and leaves the order in a state bucket it has already left. +The other order — counters first — would leave an event unclaimed whose delta had already +landed, and its redelivery would count the same money twice. Between an under-count that +heals and an over-count that compounds, this tier resolves toward the first (cross-cutting +rule (c)). + +`appliedAt` is therefore never a gate. A claim with a null stamp may or may not have moved +the counters, because the crash could have landed on either side of the write, so nothing +reads it to decide whether to apply — it exists to make the residue legible. + +Every decrement is also **floored at zero**, which is the one place this adapter tolerates +being wrong: a decrement whose matching increment was lost would otherwise drive a counter +negative and report negative revenue, a number no report should be able to show. + +### The recompute is the definition + +`reconcile(range)` rebuilds each day document from a paged scan of the orders created that +day. A recompute commits an ABSOLUTE value while a live event commits a DELTA, so running +both against one document has exactly two failure modes — the recompute erasing a +transition it did not see, and a delta landing on top of a recompute that already counted +it. Three mechanisms close them, in the order the code does them: + +1. **Pin before scanning.** Every day document an attempt may write has its revision read + BEFORE the orders are scanned, so a live delta landing in between costs the recompute + its commit and forces a re-scan. Scanning first and pinning afterwards is the bug that + ordering exists to prevent: the value in hand would predate the transition and the + revision would not say so. +2. **Absorb the claims the scan proves, before committing.** A claim is the right to move + these counters; a recompute that has counted the event absolutely spends that right, and + `absorbedAt` is how the claim says so. The claims absorbed are exactly the ones + RECONSTRUCTED from the scanned orders — never every claim an order has — because a + transition that is not in the scanned document is one the recompute did not count, and + absorbing it would drop its delta. +3. **Every delta re-reads its claim immediately before every bucket write** and skips + itself when it has been absorbed (cross-cutting rule (a): the token is re-asserted + before each write it guards, on every attempt, because this path retries with backoff + and a writer parked past the moment its right was revoked must not commit anyway). + +The claims are reconstructed from the order itself: its append-only audit log carries every +`(fromState → toState)` pair, its refunds ledger every finalized refund, and the arrival +into its original state is the event creation owes. An amount carried on a reconstructed +claim is diagnostic only — nothing recomputes from a claim. + +A day that has lost every order keeps a ZEROED document rather than being deleted: a live +event racing that write needs a revision to lose to, and an all-zero document reads as no +bucket at all. + +**Reconcile a CLOSED day as a matter of course, and a live day only on demand.** Yesterday +and older have no live events to race, so an attempt cannot lose its pin and the work is +one pass; the current day is still receiving events, so a recompute over it may have to +re-run and can leave the residue below. The page budget is per day, so a long range is +bounded by construction — a caller sweeping a large history should still chunk it, a month +at a time, to keep one call's work and one call's retries bounded. + +**The absorb pass is budgeted and indexed.** A day's claims are read by the axis they are +filed under — `date`, which is the order's creation day and so the day being recomputed — +as pages of ONE indexed query, and the pass costs **one unit per claim-index page and one +unit per claim absorbed**, the same unit a page of orders costs. A claim an earlier run +already absorbed costs neither, being skipped before any spend and any write. + +A budget refusal from this pass arrives as a `ScanPageLimitError` naming operation +`absorbReportingClaims` and option `maxReconcilePages`: the operation says it was the claims +rather than the orders that exhausted the budget, and the option is the same knob either way. + +Both shapes this replaced were unbounded in something that grows: a read per reconstructed +event is a round trip per transition every order has ever made, paid on every attempt and +every sweep, and a query per ORDER makes the cost a function of how many orders the day +holds — so a large day would exhaust its budget and never heal. Every extra round trip also +widens the window in which a live delta invalidates the pin. + +The ceiling that follows is a function of how many claims an order carries — one per +transition and one per finalized refund — rather than of the order count alone. At the +default budget, for a day whose claims are already absorbed (the steady state, and every +closed day after its first heal), the cost is `orders/100 + claims/100` units: at about two +claims per order that clears tens of thousands of orders in a day, and more claims each +lowers it proportionally. A day healed from nothing pays a unit per claim as well, which is +where the real limit sits at a few hundred orders' worth of first-time absorption per call. +Chunk a bigger history, or raise the budget. + +**The residues, all in the under-counting direction.** A transition that lands after the +scan read its order but before the absorb reaches its claim is absorbed without having been +counted, and its delta is then skipped; a process that dies between the absorb and the +commit leaves the same shape; a failed attempt leaves claims absorbed whose counters it +never committed, so a day that loses its pin repeatedly reads lower each time until a run +succeeds; and a range whose later days exhaust the page budget leaves the earlier days +committed and the rest untouched. Every one of them is a day that reads low until the next +successful run, and none of them can double-count, because nothing applies a delta whose +claim is absorbed. + +### The hook on the order store is additive, and never fatal + +`EmdashOrderStoreOptions.reporting` defaults to a no-op. It is called after the order +write it describes is durable — inside the guarded flip, past the compare-and-set that +committed and past the outbox locator, so it fires exactly once per WON write and a lost +flip owes nothing — and the four sites are the flip, `recordRefund`'s finalized insert, +`finalizeRefund`, and the create-if-absent that lands a new order (whose arrival into +`pending` the status counts need). + +Every call is wrapped in a try/catch that swallows. By the time it runs the state write +has committed, so a throw would tell the caller its transition failed when it did not — +the worst possible lie about a payment. What is lost instead is a counter, in the +under-counting direction, and the recompute restores it. The retry helper would not absorb +the throw either: it only re-runs on a retryable storage abort. + +### The window is exact, whatever instants it names + +A day document is the counters for a WHOLE day, so it can only answer for a day the window +covers whole. The interior of a window is therefore read from the documents, and each EDGE +day the window truncates — at most two, and only when a bound is not midnight — is computed +from an instant-filtered scan of that day's orders, the same machinery `topProducts` uses. + +So `created_at BETWEEN from AND to` means the same thing here as it did in the statement +this replaced, to the instant. The cost of a ragged window is visible and bounded — two +extra order scans, paid only by the caller that asks for one — and the aligned windows a +day-bounded report asks for pay nothing. + +One consequence is worth knowing before reading a ragged report: an edge day is computed +from the ORDERS, so it is exact even when the rollups have drifted, while an interior day +carries whatever its document holds.

That is the shipping/tax-rules shape, not the +inventory one. + +**The shape that would exceed it is a BATCH**, not a busy shop: a hold-expiry sweep or a +bulk fulfilment run flips many orders at once, and if those orders were placed on the same +day they all contend for one document. Past roughly the ceiling the surplus writers raise +the typed contention refusal — which the order store's hook swallows, because reporting +must never fail a transition — so the day reads low until a recompute fixes it.

No contention refusal occurs +at that size; the headroom is what the extra attempts buy, and a busier day spends more of +it before the typed, retryable refusal rather than reporting a wrong total. + +### What the reporting tier does NOT carry + +- **Nothing constructs it yet.** No caller builds `EmdashReportingStore`, and nothing passes + `reporting` to the order store, so the tier is dormant: the rollups are written only by a + store that was explicitly wired to write them. **Both collections must also be declared on + the plugin descriptor before any read can answer** — an undeclared collection is a + missing-collection error, and an undeclared index is a runtime query error, so the + declaration is part of turning this on rather than a detail of it. +- **No scheduling.** `reconcile` is a method, not a cron job. Wiring it to a periodic hook is + a later change, along with every other heal this package owes. +- **No product or stock rollups.** `topProducts` and `lowStock` are computed on read, for + the reasons above. If either ever needs a rollup it needs its own document, not another + field on the day. +- **No cash-flow view.** Refunds are bucketed by the ORDER's creation day, which answers + "what did the orders placed in this period give back". "What refunds were ISSUED in this + period" is a genuinely different report and would need its own document and endpoint. diff --git a/packages/store-emdash/package.json b/packages/store-emdash/package.json new file mode 100644 index 00000000..b6565bcc --- /dev/null +++ b/packages/store-emdash/package.json @@ -0,0 +1,54 @@ +{ + "name": "@otta-sh/store-emdash", + "version": "0.0.1", + "description": "Commerce store adapters for Otta over the EmDash plugin-storage primitives — bound to a structural StorageAccess port, never to the host at runtime.

The only + * atomicity primitives are single-document ones, so the rule is: *an invariant + * that spans two facts lives in ONE document.* The decisive fact is that an + * inventory decrement is not idempotent unless the row records who applied it — + * which puts the holds map inside the inventory document, and makes the decrement + * a single `compareAndSet` in which the guard (`onHand >= qty`, computed in JS), + * the new count and the hold record all commit together. No oversell and + * once-only are the same atom. + * + * ## Reserve is a two-step with ONE crash window + * + * `reserve` is: claim `reservation_keys/{key}` (create-if-absent, carrying the + * sku, the qty and the minted reservation id) → the inventory `compareAndSet` → + * update the key document to its terminal `ReserveResult`. The single crash window + * is **claim written, `compareAndSet` not yet run**. It is healed, not merely + * tolerated: any replayer of the key finds the `claimed` document and completes it + * deterministically, reusing the RECORDED reservation id rather than minting a + * second one, so the decrement happens exactly once and the caller gets one + * answer. A sweeper reaps claims nothing ever replays (INC-C4). + * + * What the embedded aggregate removes is the SQL adapter's *second* window — a + * `pending` reservation flipped to `held` separately from the decrement. The claim + * window cannot be removed by any single-document primitive, because the claim and + * the units necessarily live in different documents. + * + * ## The outcome-before-prune ordering + * + * A hold is pruned on commit/release, so the terminal `ReserveResult` is written + * to the key document **before** the prune, and a replay reads that document + * first. Prune-first-then-crash would let a replay conclude the key was fresh and + * decrement a second time. The prune is the second, idempotent step. + * + * That *ordering* is only observable under fault injection, which is INC-A3's + * tier, not this file's: the suites here pin the consequence (a replay after a + * prune still answers from the key document) rather than the order of the two + * writes. + * + * ## What is NOT atomic + * + * `adopt` / `adoptMany` / `commitMany` / `releaseAdopted` take reservation ids + * with no sku, and one order's holds can span N SKUs — i.e. N documents. **These + * methods are N per-SKU writes and are not atomic across SKUs.** Every write is + * idempotent by reservation id (a hold already in the target state is a no-op + * success), so a partially applied set is safe for any replayer to re-run to + * completion; the order-side intent record that says *which* set was meant, and + * the sweeper that completes it, are separate increments (INC-B2 / INC-C4). The + * implementation therefore classifies every id first (index lookups), then + * applies the work grouped by SKU — one `compareAndSet` per SKU, not per id. + * + * ## Contention + * + * Read-modify-write on a hot SKU retries.

Here the guard is + * `order_keys/{idempotencyKey}` (ADR-0019 §7.9), and the order of the two writes + * is load-bearing: + * + * 1. **Claim** `order_keys/{key}` create-if-absent, carrying the WHOLE prepared + * order document — order id, minted line ids, timestamps, everything — so any + * replayer finishes the create byte for byte instead of minting a second set of + * ids. A refused claim means the key has already minted an order: the call is a + * replay and returns `{ created: false, order }`. + * 2. **Create** `orders/{orderId}` create-if-absent from the claim's payload. One + * write carries header + `readonly items` + totals + address together, which is + * where the SQL's multi-row `order_items` insert, its 1:1 `order_totals` row and + * its conditional `order_shipping_address` row all went. + * 3. **Promote** the claim to `terminal`, dropping the payload. NEVER before + * step 2: a terminal key pointing at a non-existent order reads as "already + * minted" and would lose the checkout. + * + * The window is "claim written, order document not yet created", and it is + * HEALED rather than tolerated — `createFromCart` and `getByIdempotencyKey` both + * complete a `claimed` key they find, which is why the payload is carried at all. + * + * **Snapshot immutability is structural, not a discipline.** {@link OrderDoc.items} + * is `readonly OrderItemDoc[]` with every element field `readonly`, and it is + * written ONLY by step 2. Every later write in this file is `{ ...doc, … }`, which + * carries that very array by reference — so there is no code path, and cannot be + * one without a compile error, that rewrites a price or a title after purchase. + * + * ## The transition is ONE write + * + * ADR-0019 §7.10: the guarded flip, the appended audit event and the first-wins + * outbox entry are a SINGLE `compareAndSet` guarded on the document revision AND + * on `state === fromState` (plus, for expiry, on the deadline). So: + * + * - "flipped but no event" is unreachable, as it already was under the SQL's + * transaction; + * - the outbox once-only is per `(orderId, toState)` — an entry is appended iff + * none with that target state exists, which is where + * `UNIQUE(order_id, to_state)` went. It is NOT per event; + * - a lost race is a clean no-op: the guard fails, nothing is written, and no + * event is recorded (audit never double-counts a replay). + * + * ## The three hold brackets — the one real cross-aggregate edge + * + * Adopting, committing and releasing an order's reservations writes N inventory + * documents, and no primitive can bracket them with the order write. So each is + * ADR-0019 §1's other shape — **intent, per-id idempotent write, completion** — + * and the intent is recorded IN the order document, in the same write as the state + * change that implies it: + * + * | Bracket | Intent recorded by | Per-id write | Completed by | + * |---|---|---|---| + * | adopt | `createFromCart` (before the use-case's `adoptMany`) | `adoptMany`, idempotent per reservation id | {@link EmdashOrderStore.completeHoldAdoption} | + * | commit | the `→ paid` flip (before settle's `commitMany`) | singular `commit` per id | {@link EmdashOrderStore.completeHoldCommit} | + * | release | the `→ expired` AND `→ cancelled` flips | `releaseAdopted` per id, order-scoped | {@link EmdashOrderStore.completeHoldRelease} | + * + * The cancellation leg is the one the SQL adapter had no analogue for (its cancel was + * a pure envelope write): a cancelled order no longer claims its holds, so it records + * the same intent expiry does. `releaseAdopted`'s ADOPTED-ONLY guard is what makes that + * safe on a PAID order cancelled after settle — a `committed` hold is not adopted, so + * the release is an unconditional no-op and spent units are never returned. + * + * An intent whose `completedAt` is `null` is the marker that work is owed; each + * completion is idempotent and callable by ANY replayer, which is what makes a + * partial batch safe. The commit completion drives the **singular** `commit` per + * id rather than re-running `commitMany`, because ADR-0019 §2 is explicit that + * `commitMany` SKIPS an already-`committed` id: a SKU caught between its terminal + * record and its prune is finished by the singular call, never by the batch. + * + * ## The refund ceiling is one write on this document + * + * `min(Σ captured, frozen total)` was computed under a row lock on `orders` so two + * concurrent refunds could not each read the same headroom. Here `payments[]` and + * `refunds[]` are fields of the very document the refund is appended to, so the + * ceiling, the ACTIVE-capacity arbitration and the row all live inside ONE + * compare-and-set — the revision doing what the lock did. The four-state capacity + * lifecycle (ADR-0019 R6) is read and written in that same step: `reserved` and + * `unverified` HOLD capacity, `voided` releases it, and `finalizeRefund` is + * status-guarded and NEVER re-arbitrates, because its reservation already holds what + * it is about to finalize. `refund_keys/{key}` exists because the settle half of the + * protocol carries only the key — and, like `order_keys`, it carries the whole + * prepared row so a crash before the order write is completed rather than re-minted. + * + * Fulfillment and cancellation ride the same guarded flip as every other state + * change (`#flip`'s `envelope`), never a parallel copy of it; cancellation also + * records the release intent, because a cancelled order no longer claims its holds. + * + * ## The email-outbox lease landed here, ahead of its increment + * + * The fulfillment and cancellation specs both assert that exactly ONE notification + * DRAINS, which runs `dispatchOrderEmails` — so `claimNextEmail`, `markEmailSent` + * and `rescheduleEmail` are a dependency of this increment's own gate, the way + * `recordPayment` was a dependency of the previous one's. They implement ADR-0019's + * R2: the SQL's OR-and-negation claim predicate becomes the single denormalized + * {@link OrderDoc.emailDueAt} index, and the claim re-applies that predicate to the + * entry it picked inside one compare-and-set. + * + * ## The whole port is implemented + * + * Every `OrderStore` method has a real implementation: the lists, the search, the + * counts, the customer view, guest linking and the outbox settle path were the last + * four, and there is no `NotImplementedInIncrementError` left to throw anywhere in this + * package. What the ADMIN LIST cannot do is narrower and is a matter of SEMANTICS rather + * than of a missing method: the port's `search` documents an unanchored `buyer_ref` + * SUBSTRING, and the host's filter algebra has no substring operator — so that arm is + * served as a PREFIX (ADR-0019 §6.1's ratified narrowing).

That is the user-visible narrowing + * ADR-0019 §6.1 ratified, and it is pinned here so it is a decision rather than a bug; + * - **the customer key is a UNION of two indexed arms**, and `countOrders` takes it by + * inclusion–exclusion — so an order matching both halves is counted once; + * - **`linkGuestOrders` rewrites `customerKey`**, or the customer filter would stop + * finding an order the moment it was linked (ADR-0019 R3); + * - **the by-sku index heals idempotently**: a deleted index document is rebuilt by a + * replay, and rebuilt ONCE; + * - **the locator**: a settle finds its entry by id with no index walk, and a settle of + * an already-drained entry is a no-op. + * + * It is a plain module rather than a `.test.ts` for the same reason + * `order-cancellation-release.ts` is: D1's spec cannot import a `.dialects.test.ts`, + * which pulls in `better-sqlite3` and `pg` at module scope. + */ +import { + cents, + currency, + customerId as brandCustomerId, + idempotencyKey, + orderId, + productId, + reservationId, + sku as brandSku, + type CreateOrderInput, + type OrderStore, +} from "@otta-sh/domain"; +import { expect, test } from "vitest"; +import { + collectionOf, + foldSku, + ORDER_SKU_INDEX_COLLECTION, + orderSkuIndexId, + ORDERS_COLLECTION, + OUTBOX_KEYS_COLLECTION, + type OrderDoc, + type OrderSkuIndexDoc, + type OutboxKeyDoc, + type StorageAccess, + type StorageCollection, +} from "../src/index.js"; +import { makeOrderHarness, type OrderHarness } from "./order-harness.js"; + +const USD = currency("USD"); + +/** An order carrying REAL frozen lines, through the port's own `createFromCart`. */ +async function lined( + store: OrderStore, + input: { id: string; skus: readonly string[]; buyerRef?: string }, +): Promise { + const unit = 500; + const lines: CreateOrderInput["lines"] = input.skus.map((s, i) => ({ + productId: productId(`p-${input.id}-${String(i)}`), + sku: brandSku(s), + title: "Widget", + unitPrice: cents(unit), + currency: USD, + quantity: 1, + fulfillmentKind: "physical", + reservationId: reservationId(`res-${input.id}-${String(i)}`), + })); + const total = cents(unit * input.skus.length); + await store.createFromCart({ + orderId: orderId(input.id), + cartId: "cart-1", + currency: USD, + idempotencyKey: idempotencyKey(`key-${input.id}`), + holdExpiresAt: "2026-07-10T00:15:00.000Z", + buyerRef: input.buyerRef ??

When a WHERE guard makes the statement a no-op (same-key replay or - * stale sync), `RETURNING` yields no row, and the current row is re-read - * with one follow-up `SELECT`. - * - * CONCURRENCY, on the sku-bearing path only: the rename carry moves real units, - * so it IS a race target, and `test/sku-rename-race.pg.test.ts` covers it on - * Postgres (concurrent renames through both writers, a rename against the seed - * that can contend its claim, and a rename against a restock of the sku it is - * leaving). The no-sku path is unchanged and remains none of that. - * - * Live-sku uniqueness is the migration's partial unique index - * (`UNIQUE (sku) WHERE deleted_at IS NULL`, review S3) — the `ON CONFLICT` - * target stays the `product_id` PK, so the partial index never arbitrates - * the upsert; a genuinely conflicting live sku surfaces as a constraint - * error on both dialects, and a soft-deleted row's sku is reusable. - * - * ─── THE LOCK ORDER ──────────────────────────────────────────────────────── - * - * The VARIANT writers take row locks in one order, and this is the only place it - * is written down: - * - * product_commerce → inventory, IN SKU ORDER → product_variants - * - * Skipping a stage is always allowed; taking one out of order is not. - * - * WHAT IS ACTUALLY PROVED, stated as the obligation rather than as a slogan, - * because "one total order" is stronger than what holds here: - * 1. Every variant writer that will APPLY takes the parent's lock first — except - * the single-lock writer in (2), which needs no ordering to be safe. Two - * writers under one product therefore never interleave at all, which makes - * every intra-product cycle unreachable rather than merely ordered — including - * the one inside `product_variants_live_sku_unique`. - * 2. Writers that take at most ONE lock cannot participate in a cycle, since a - * cycle needs someone waiting while holding. `deactivateVariant` is a single - * conditional UPDATE and is in that class. - * 3. Across DIFFERENT parents, the only shared resources are `inventory` rows, - * and those are taken in sorted sku order by every writer that takes two. - * 4. The `couldApply`-FALSE branch of `updateVariantFields` skips the parent lock - * and so is outside (1). It is cycle-free only because such an edit never - * applies, and THAT rests on the monotonic-clock assumption named on - * `updateVariantFields` — the same assumption its guard 4b already rests on. - * If that assumption is ever false, this branch is the second thing to fix. - * 5. `#applyVariantDeclare` is the one deliberate inversion: it cannot know which - * sku to lock until it has read the row, so it takes the parent, then the - * variant row, then at most ONE `inventory` row. It never holds two stock rows, - * and every writer that could wait on its variant row holds the parent it - * already owns — so it closes no cycle. Raced directly against a price edit of - * the SAME variant in the variant race suite. - * - * WHY THIS ORDER, rather than any other: - * - `product_commerce` FIRST because it is the aggregate root — a product's - * currency is a fact about the product, so both the product's own repricing - * and any variant's pricing have to agree under one lock. - * - `inventory` before `product_variants`, which is the opposite of what the - * reading order suggests and is the whole lesson of this class. A variant's - * guarded UPDATE looks like the decision that precedes the movement, but - * writing a sku also takes an entry in `product_variants_live_sku_unique`, - * and two writers crossing skus each end up waiting on the other's - * uncommitted index entry — a cycle formed inside the index, before either - * has touched a stock row. - * - `inventory` rows IN SKU ORDER — sorted, never by role. A carry touches two - * of them, and which is "source" and which is "target" belongs to the caller - * rather than to the rows: two crossing renames, X→Y and Y→X, disagree about - * role order on the same pair, so ordering by role is ordering by nothing and - * they deadlock (measured: `40P01` around one loop in 250). Sorting gives every - * writer one agreed order over any pair. - * - * KNOWN, PRE-EXISTING, AND NOT ADDRESSED HERE: the PRODUCT-side writers have the - * same exposure this order closes for variants, and it predates variants. `upsert` - * and `#applyCommerceFields` write `sku` in their guarded statement, which takes - * an entry in `product_commerce_live_sku_unique`, BEFORE any `inventory` lock — so - * two products renaming onto each other's skus can deadlock inside that index - * exactly as two variants could. Restructuring them is deliberately out of scope - * for the change that introduced variants: it touches the two writers the whole - * catalog runs through, and it deserves its own change and its own race. Recorded - * so the next reader finds a known follow-up rather than an oversight. - * - * WHY IT IS WRITTEN DOWN RATHER THAN INFERRED. Every lock here is a portable - * self-assignment `UPDATE` (`FOR UPDATE` is not SQLite), so the locks are - * invisible at the call sites that need them and are easy to add in the wrong - * place. A violation does not fail a unit test: better-sqlite3 serializes every - * writer onto one connection and cannot deadlock at all, so an inversion is - * green on the fast tier and surfaces only on Postgres, as an unmapped `40P01` - * reaching a merchant instead of the typed refusal this port documents. The - * race suites (`test/sku-rename-race.pg.test.ts`, - * `test/variant-sku-rename-race.pg.test.ts`) are where that is caught, and each - * inversion this order rules out has a case named after it. - */ -export class KyselyProductCommerceStore implements ProductCommerceStore { - readonly #db: Kysely; - readonly #clock: Clock; - - constructor(options: KyselyProductCommerceStoreOptions) { - this.#db = options.db; - this.#clock = options.clock; - } - - async upsert(input: UpsertProductCommerceInput, key: IdempotencyKey): Promise { - if (typeof input.productId !== "string" || input.productId.length === 0) { - throw new MissingProductIdError(); - } - // No sku in play ⇒ no rename is possible ⇒ the statement stays exactly - // what it was, on the plain connection.

So a - * row that failed the CAS at pre-read time can pass it at statement time only - * if some writer moved `updated_at` BACKWARDS onto the exact value the caller - * quoted — i.e. only under a non-monotonic clock. THAT IS THE ASSUMPTION, named - * here rather than left implicit: a `Clock` that can go backwards breaks the - * optimistic-concurrency design of this whole port long before it reaches this - * optimization.

Measured at 50k rows / 90% NULL: 304 kB - * vs. 464 kB for the plain form, and the plan drops a `Sort` node. - * `linkGuestOrders`' `WHERE customer_id IS NULL` half is unaffected — that - * predicate is excluded from this index by construction and is driven by - * `idx_orders_buyer_ref_lower` instead, with `customer_id IS NULL` applied - * as a heap filter. The customer-key union (`customer_id = :id OR - * lower(buyer_ref) = lower(:buyerRef)` in `orderFilterConditions`) still - * uses this index for its `customer_id = :id` half: the planner proves - * equality to a literal implies `IS NOT NULL` and picks the partial index. - * - `idx_orders_buyer_ref_lower` is a FUNCTIONAL index on `lower(buyer_ref)`. - * Its consumers are the EQUALITY predicates on `buyer_ref`, each folded at - * the compare side (`lower(buyer_ref) = lower(:buyerRef)`): - * `KyselyOrderStore#linkGuestOrders` and the `customer` key half of - * `orderFilterConditions` (`customer_id = :id OR lower(buyer_ref) = - * lower(:buyerRef)`) in `kysely-order-store.ts`.

A - * plain b-tree on `buyer_ref` would never be chosen by the planner for the - * equality queries either, so the index expression matches `lower(buyer_ref)` - * exactly — Postgres resolves an unqualified vs. `orders.`-qualified column - * reference to the same parsed expression node, so this one expression serves - * both call-site spellings. - * - * WHAT THE TEST ACTUALLY PINS. `order-lookup-indices.test.ts` EXPLAINs the - * three statements above (`listForCustomer`, `linkGuestOrders`, the customer - * key) and asserts each plan names the index it was built for. That catches a - * rewrite of THOSE predicates — a different fold, a column swap — by failing - * loudly rather than silently losing the index. It does NOT cover every - * predicate in the store, and never covered `search`; a query the test does - * not EXPLAIN can drop off an index with nothing turning red. - * - * Neither duplicates the existing `orders` indices: `idx_orders_created_state` - * (`created_at, state`, `0008`) and `idx_orders_created_id` (the admin keyset - * `created_at, id`, `0009`). - * - * No `CONCURRENTLY`: matches `0008`/`0009` precedent (plain `createIndex`, - * cheap insurance rather than a performance target) and the migration runner - * wraps each migration in a transaction, inside which `CREATE INDEX - * CONCURRENTLY` cannot run on Postgres. - * - * SQLite equivalent: no dialect fork needed. SQLite has supported expression - * indices and partial indices since 3.9.0/3.8.0, and `lower()` is standard - * SQL on both dialects (the same claim `linkGuestOrders` already relies on). - * `idx_orders_customer_id` is built with the portable Kysely column/`where` - * builder, which is genuinely dialect-agnostic. `idx_orders_buyer_ref_lower` - * instead uses a raw `sql` fragment (`column(sql\`lower(buyer_ref)\`)`) — the - * builder has no typed API for an expression column, so this one is NOT a - * portable-builder construct. It still emits byte-identical DDL on - * better-sqlite3 and pg, but only because `lower(x)` happens to be spelled - * the same on both dialects; a less portable expression here would need an - * explicit per-dialect branch.

It exists because the plan's own definition of done (item 13) +asks for it: the outcome, the measured numbers behind R2/R3/R6/R7, the pinned host SHAs and +migration number, the conflict resolutions, what was deleted, and whatever INC-D6 has to +reconcile. + +Every figure below is cited to the artefact it was read from. Where a number the plan asked for +was not found recorded anywhere, this note says so rather than supplying a plausible one — an +invented number in a historical record is worse than an acknowledged gap. + +--- + +## 1. The outcome + +**One deployable.** The EmDash site Worker is the only thing that ships. The Otta plugin owns all +money and stock truth **in-process**, on the host's per-plugin document store (`ctx.storage`), +through the `@otta-sh/store-emdash` adapter — one document per aggregate, compare-and-set writes. +There is no separate commerce service, no second database, and no second mode. + +Deleted outright in Phase D: `@otta-sh/service`, `@otta-sh/store-postgres`, `HttpCommerceClient`, +the four admin HTTP clients, and the `commerce.mode` flag. Details in §4. + +The decision itself is recorded in +[ADR-0020](../adr/0020-one-deployable-plugin-owns-commerce-truth.md) (one deployable; ADR-0002 is +partially superseded by it), resting on +[ADR-0018](../adr/0018-plugin-owns-commerce-truth-in-process.md) (the plugin owns commerce truth +in-process) and [ADR-0019](../adr/0019-commerce-aggregates-are-one-document-each.md) (one document +per aggregate). ADR-0020 also records the re-derivation path: a future service would be rebuilt +from the unchanged domain ports, not kept on standby, so the deletion is not mistaken for a lost +capability. + +**The price paid, not just the wins.** The fold-in accepted one genuine loss, and ADR-0020 §2 +records it rather than minimising it: the Stripe API secret — previously an environment variable on +a separate Worker, behind an HTTP boundary — now lives in the plugin's write-only `kv` and is +readable inside the very process that renders storefront pages and the admin console, so a +code-execution bug anywhere in the plugin reaches it. Read +[ADR-0020 §2](../adr/0020-one-deployable-plugin-owns-commerce-truth.md) for what bounds that +(write-only persistence, non-ambient egress gated by a build-time `allowedHosts` allowlist, an +IO-free domain) and for its honest caveat: `@otta-sh/payments-stripe` defaults its transport to +`globalThis.fetch` rather than `ctx.http.fetch` — unlike the x402 facilitator client and the email +sender — so the allowlist bound does not yet apply to it; the secret is stored but no live call +site constructs the Stripe gateway with a real transport, which makes this latent rather than +exploited, and makes passing `ctx.http.fetch` mandatory for whoever wires it up. + +--- + +## 2. The measured numbers (R2, R3, R6, R7) + +### R2 — CAS contention and the retry budget + +R2 has **no structural fix**: a hot aggregate is written by read-modify-write, so a hot SKU +retries. That makes the measured retry depth a **permanent contention budget**, not an interim +figure — which is why the plan requires it to be repeated here. + +The constants, from `@otta-sh/store-emdash`: + +| Constant | Value | +|---|---| +| `CAS_MAX_ATTEMPTS` (package ceiling) | **24** (raised from 12 on 2026-09-14) | +| `CAS_ATTEMPT_BUDGET` (hand-set test budget, deliberately tighter) | **8** | +| Backoff | full-jittered, first delay **2 ms**, doubling to a **50 ms** cap (`CAS_MAX_DELAY_MS`) | + +Measured depths: + +| Shape | Measured attempts | +|---|---| +| Inventory flash sale — 5 units, 50 racers, 20 loops | **5–6** | +| Inventory — 1 unit, 100 racers | **2** | +| Single-line checkout — M=5, N=40, 8 loops | **6–7** | +| Multi-line checkout — M=8/sku, 10 carts, 3 lines, 6 loops | **9–10** of 24 | +| Ten partial refunds under one ceiling — N=20 callers, 100 each against 1,000, injected gateway latency | **11** | +| Restock +10 racing 40 reserves on 5 units | **13** of 24 | +| Restock then 40 reserves on 15 units (sequenced) | **12** of 24 | +| 20 removals racing 20 reserves on 12 units, 15 loops | **15** of 24 (the deepest recorded shape — see the exception below) | +| Full-ceiling refund shapes | **2** (losers are refused by arbitration before writing) | +| Coupon counter step (`redeem`), 50 racers on a 5-use cap | **2** (asserted as a hard bound, `<= 2`) | + +**R2's one documented exception.** An adversarial merchant shape — 20 `removeStock` racing 20 +reserves on 12 units, 15 loops, 600 calls — is the deepest shape the suite measures. The cause is +that a refused `removeStock` still writes its ledger entry, so writes are not bounded by units the +way reserves are. + +**Pre-raise (12-attempt ceiling).** This shape sat *at* the ceiling and raised the typed contention +error, with **11–29** typed contention failures per run. That was the measurement that motivated +raising the ceiling. + +**Current (24-attempt ceiling).** The same shape now measures **15 of 24 attempts with 0 typed +contention failures** — two or three attempts deeper, and no caller is told "too busy" any more. +The assertions themselves are unchanged upper bounds and held across the raise without being +touched: depth `<= CAS_MAX_ATTEMPTS`, typed failures **`<= 90`** (15% of the 600 calls). + +Both reviewers judged this correctly characterised and not a shopper-safety hole, because the +contention error is typed and retryable and never collapses into `OUT_OF_STOCK`. Two follow-ups +were opened at the time: the +storefront cart route must map `StorageContentionError` to a 503 plus retry, and a later adapter +pass should stop `#applyStockClaim` writing the aggregate for a refused `INSUFFICIENT_STOCK` +removal, which would restore the unit bound on write depth. + +The ceiling was raised from 12 to 24 because the refund shape above measured 11 — one attempt +under the old ceiling — which made an exhausted budget a flake rather than a signal. The extra +attempts only buy jittered backoff; no invariant depends on the attempt count, because every +invariant is enforced by the guard inside the write. + +Exhaustion surfaces as a typed, retryable `StorageContentionError` — never `OUT_OF_STOCK`. A +shopper who could have bought is never told the item is out of stock. + +**Sources:** `packages/store-emdash/README.md` §"Contention budget" and §"Coupon contention, +measured" (the live tables, which is where they are re-measured); +[ADR-0019](../adr/0019-commerce-aggregates-are-one-document-each.md) §"The contention budget, as +numbers". ADR-0019 explicitly defers to the package README for live figures, so cite the README +rather than the ADR's table, which predates the ceiling raise. + +### R3 — document size against D1's row limits + +Measured on the busiest shape, a three-line order with a full ship-to snapshot, via +`JSON.stringify(doc).length` on the sqlite tier: + +| Shape | Size | +|---|---| +| On creation | **2,237 B** | +| After five transitions (five audit events + five outbox entries) | **4,081 B** | +| Plus two captured payments and three refunds | **5,164 B** | +| `order_keys` document, terminal | **109 B** (≈2.3 KB while a claim carrying the payload) | +| `refund_keys` document, terminal | **159 B** (≈400 B while a claim) | + +All three order figures are **asserted, not remembered**: `order-flow.dialects.test.ts` builds that +order, prints the sizes, and holds them under an **8 KB cap**. The busiest measured shape is still +under two thirds of the cap, so the cap is unchanged. A row-size regression — an unbounded ledger, +a re-embedded snapshot — fails a test rather than surfacing as a slow read. + +Growth is bounded by the state machine rather than by pruning: at most nine transitions per order, +≈370 B per transition (event plus outbox entry), ≈180 B per capture, ≈220 B per refund row. +`events` is deliberately unbounded because it is the audit spine the port promises. The one ledger +with no natural bound — per-order notes — is therefore not in this document at all. + +**Honest caveat on the plan's wording:** the plan asked for a **p99** document size. What was +actually measured and asserted is the size of the busiest realistic shape against a hard 8 KB cap, +not a percentile over a population of real orders. That is a stronger guard for a pre-launch system +with no order population to take a percentile over, but it is not literally a p99, and this note +records the distinction rather than relabelling the figures. + +**Source:** `packages/store-emdash/README.md` §"Measured document size". + +### R6 — Worker bundle size + +**PARTIAL — a real before/after number exists from INC-A6, but not the full figure the plan asked +for, and not at INC-B10a where it was supposed to be recorded.** + +R6 had two halves. The **correctness** half shipped and is asserted: INC-A6 promoted +`@otta-sh/domain` and `@otta-sh/store-emdash` to `dependencies` of `@otta-sh/plugin` and inlines +both via tsdown `noExternal`, and `packages/plugin/test/bundle-imports.test.ts` builds the real +bundle through the package's own `tsdown.config.ts` and fails if a bare `@otta-sh/*` specifier +survives or a runtime `emdash` import appears (the latter being ADR-0018's "zero EmDash runtime +dependency" rule, which depcruise enforces on source but cannot see in the emitted graph). + +The **measurement** half is partial. INC-A6 (PR #252) captured a genuine before/after build: + +| | Main chunk | Gzipped | Total dist (14 files) | +|---|---|---|---| +| Base — domain/store-emdash still external | 510.35 kB | 154.60 kB | 1.81 MB | +| Head — both inlined via `noExternal` | 521.40 kB | 158.75 kB | 1.84 MB | +| **Delta** | **+11.05 kB** | **+4.15 kB** | **+30 kB** | + +Two caveats that stop this being the answer to R6: + +1. **It excludes the payment gateways.** Both were admitted into the plugin's perimeter later, and + in two separate increments: `@otta-sh/payments-stripe` at **INC-C1b (PR #276)**, which added it + to `tsdown.config.ts`'s `noExternal` and the workerd harness list, and `@otta-sh/payments-x402` + at **INC-C5 (PR #281**, commit `5f304d1`**)**, when the in-process x402 settle path made + `payments/x402-wiring.ts` a real runtime import. No build-size log was captured at either. R6's + concern is the Worker gaining the domain, `store-emdash` **and both payment gateways**; this + measures the first two only. +2. **It is a `dist/` build figure, not a deployed Worker figure**, and it is not the INC-B10a + measurement the plan called for. INC-B10a (PRs #267/#268) recorded no bundle size at all — its + evidence notes only a generic build stat ("14 files, 3.70 MB"), which is dist output including + `.d.mts` and `.map` files. + +Searched to establish this: every merged PR body from this work order (#246–#293) for "bundle +size", "gzipped", "KiB" and related terms; the run log, whose INC-B10a entries discuss the bundle +*guard* but record no size; `/home/azureuser/otta-work-orders/evidence/` including `inc-a6`, +`inc-b10a-1` and `inc-b10a-2`; and the repo tree's source, ADRs and plans. Other bundle figures in +the tree are unrelated — `sites/staging/src/lib/coil.ts` (6.1 kB per coil, 2.2 kB gzipped), +ADR-0014's +0.19 KiB gzipped for the second native descriptor, and the harness note that the host's +own `PluginRegistry.js` is 7.94 MB raw / 1.90 MB gzipped before any Otta code. + +So: the guard that the bundle is *correct* exists and holds; the delta for admitting the domain and +the store adapter is a real +4.15 kB gzipped; but **the total deployed Worker size with the payment +gateways included was never measured or recorded**. Anyone closing this should measure it with +`wrangler deploy --dry-run` on `sites/staging` (what ADR-0014 used) rather than assuming the +absence of a number means the result was fine. + +### R7 — D1 write throughput + +**NOT FOUND — flagged as an open gap.** + +The plan's mitigation reads: "Accepted as the price (D5 reason 5). Record a measured +writes/second figure from the D1 tier so the limit is a number. Pre-launch, this is theoretical; +ADR-0020 records the re-derivation path if it ever stops being." + +No writes/second figure was found recorded anywhere. Searched: all merged PR bodies #246–#293 +(including INC-A4's PR #250, the real-D1 tier, and INC-D2's PR #285, the D1 tier release gate) for +"throughput", "writes/s" and "writes per second" — zero hits; the run log; the evidence directory; +and ADR-0018/0019/0020, which discuss D1 as the storage floor and its *contention* behaviour as a +measured budget, but state no throughput number. + +The D1 tier itself is real and green — INC-A4 recorded 82/82 with no divergence, and it is a hard +gate — so what is missing is specifically the **throughput figure**, not the D1 coverage. The plan +itself notes this is theoretical pre-launch; it becomes real the moment there is traffic, and it is +the only storage ceiling left now that Postgres is gone. + +> **Summary of the four:** R2 and R3 have real, asserted, in-repo numbers. **R6 and R7 do not have +> the figure the plan actually asked for** — R6 has a real but incomplete number (a +4.15 kB +> gzipped delta that excludes both payment gateways and was not taken at INC-B10a), R7 has no +> number at all. Both are recorded here as open gaps rather than filled with estimates. + +--- + +## 3. The vendored host build: pinned SHAs, migration number, conflict resolutions + +Otta's commerce data needs conditional-write primitives (`updateIf`, `getVersioned`, +`compareAndSet`, `compareAndDelete`) that were only partly released. `updateIf` was merged into +upstream `main` (#2169); the revision-based conditional writes (#2980) were still an open pull +request. Rather than wait for a release or ship a reference implementation that would immediately +drift, the repo vendored a locally built **merge of the two**, packed as tarballs under `vendor/` +with `file:` overrides in `pnpm-workspace.yaml`. + +### The pins + +| | | +|---|---| +| Base | upstream `main` at **`ea2ccd548f7aba9883bc1c9d0cf3c6f642c10a62`** (package version `0.37.0`; already carries #2169) | +| Merged onto it | #2980, head **`c4b441b05221d936e62a28e2c33214912a7a231a`** | +| Merge commit | **`39ff8569c914853fa7fde1720632caa6ba4ac91c`** | +| Branch head the tarballs were built from | **`2dc708318d358631ab0620aded3d2afc0bac6de9`**, on branch `otta/emdash-cas` | +| Migration number used | **`077_plugin_storage_revisions`** | +| Tarball version | `0.37.1-otta.1` — the base patch bumped and suffixed, so it can never be mistaken for a published release | + +The merge branch is pushed to Otta's own fork and never force-pushed, because it is what the +tarballs were built from. Nothing was proposed upstream. + +### The conflict resolutions + +Both sides add methods to the same storage surfaces, so almost every conflict was "keep both". The +resolutions, in short: + +1. **The migration-number collision — the load-bearing one.** #2980 adds + `076_plugin_storage_revisions`; the base already ended at `076_collection_nav_group`. The + migration was renumbered to **`077_plugin_storage_revisions`** — the file, its three `.ts` + importers, and the runner's import alias and map key. +2. **Type re-exports** (core's root and plugin entries, plugin-storage repository): keep both + sides' exported type names. +3. **The sandbox bridge protocol, host implementation and in-sandbox wrapper**, for both Cloudflare + and workerd: keep both sides' operations. +4. **The migrations integration test**: take #2980's form, which slices the runner's exported + migration-name list rather than restating the tail by hand. +5. **The workerd integration test**: keep both sides' cases as two separate tests — a textual "keep + both" interleaves them into one broken block. +6. **The base's D1 `updateIf` test** builds its storage table by hand and needed the `revision` + column the merged repository now writes on every write. +7. **The storage documentation page**: keep both sections. + +**Plus one post-merge fix-up, which is not a conflict resolution.** The keep-both on the Cloudflare +sandbox bridge's `import type … from "emdash"` list left behind a `NumericDelta` import that +neither parent uses. The host lints with `oxlint --type-aware --deny-warnings`, so the merge commit +itself does not lint even though both of its parents do. The fix is the one commit on top of the +merge — which is why the build records a **branch head** as well as a merge commit, and why the +build script reuses the recorded head. + +### The migration-name hazard (R13) + +Recorded because it outlives the vendoring. If upstream eventually lands the conditional-write +migration under a number other than `077`, a database migrated by this build carries a migration +name the released runner does not know. The sharp edge is that `runMigrations` short-circuits on +`appliedCount >= MIGRATION_COUNT`: a database migrated by this build holds 76 rows, one of them +`077_plugin_storage_revisions`, so when the pin moves to a stock release that also has 76 +migrations, the fast path returns "nothing to do" and upstream's real `077` is **silently never +applied**. Applied rows must be compared by **name**, not by count. Staging is the only database +that can reach that state, and it is re-seeded demo data. + +> **Where the detail lives now.** `vendor/README.md` held the full record behind this section — the +> tarball inventory and why each was required, why each override was load-bearing, and the +> de-vendoring checklist.

It had to be built +incrementally because INC-A7 found the premise weaker than the spec assumed: of the 165 assertions +in the eight HTTP-client test files, only **28 were transport-agnostic**; the rest were HTTP wire +mapping. So each increment added its own slice — INC-B10a (PRs #267/#268, the storefront slice, +26→53 cases per tier), INC-B10b-i/ii (the admin products and orders slices), INC-B10c-i +([#272](https://github.com/UrumiAI/otta.sh/pull/272), the admin rules slice, widening the shared +surface from 18 to all 25 methods) and INC-B10c-ii +([#273](https://github.com/UrumiAI/otta.sh/pull/273), reporting and settings, from a 1-method stub +to all 6) — and only with all of them green against both tiers was the proof real. Two deletion +orders were load-bearing and were respected: the +`Kysely*Store` SQL guards are the semantic reference for every Phase-B adapter, so **ADR-0019 +snapshots them in prose** before D3b; and the race files were re-pointed at `store-emdash` and +green before their `store-postgres` originals were deleted. + +**The Postgres CI container stays.** The race gate is `store-emdash` over real Postgres. Deleting +`store-postgres` did not delete the integration job — `better-sqlite3` verifies the SQL, not the +race. + +The in-process replacements live in `packages/plugin/src/admin/`: `InProcessAdminOrdersClient`, +`InProcessAdminProductsClient`, `InProcessAdminRulesClient`. + +### Verified absent + +Checked against the branch this note was written on: + +- `packages/service` and `packages/store-postgres` — both gone. `packages/` now holds + `admin-presentation`, `admin-react`, `domain`, `payments-stripe`, `payments-x402`, `plugin`, + `store-emdash`. +- `HttpCommerceClient` — the **class definition** is gone; the only occurrence in live source is + a comment in `packages/plugin/test/make-commerce-client.test.ts` recording that D3a retired it. + **But stale live-doc references remain**, and they are an open follow-up, not this increment's + job to fix: `CLAUDE.md` still describes running the client-side contract suite against + `HttpCommerceClient` over a live test server as the HTTP-task verification path (line 95), still + says two tiers "need a backing service" (line 52), and still says the plugin "reaches the service + **only** via `ctx.http` + `allowedHosts`" (line 37); `packages/plugin/README.md:15` still lists + `HttpCommerceClient` as a current plugin export ("the commerce service over `ctx.http`. + Transitional."); and `packages/plugin/test/contracts/README.md:5` still refers to it in the + present tense.

What INC-D6 had to reconcile + +**Nothing. That is the finding, and it is the good one.** + +INC-D6 ran on 2026-09-20 against `emdash@0.38.0`, published 2026-09-15, the first release cut after +#2980 merged upstream (`570333ac`, 2026-09-14). The swap was: +`emdash` and `@emdash-cms/cloudflare` `0.37.0` → **`0.38.0`**, `@emdash-cms/admin` → **`0.38.0`**, +`@emdash-cms/registry-client` → **`0.6.0`**. + +### R13 did not materialize + +The released `0.38.0` numbers the conditional-write migration **`077_plugin_storage_revisions`** — +the same name the vendored merge renumbered it to. Stronger than that: the released build's +`src/database/migrations/runner.ts` is **byte-identical** to the vendored build's (519 +lines, `diff` silent), `runner.ts`'s migration list is identical, and both builds carry +**76** migrations in the same order (`001`–`009`, then `011`–`077`; there is no `010` in either), +with `077_plugin_storage_revisions` last in `MIGRATION_NAMES` in both. + +So the fast-path hazard below has no way to fire on this swap: a database migrated by the vendored +build holds exactly the rows the released runner expects, by name. **No staging D1 rename was +needed and none was performed** — no `wrangler d1 execute`, no deploy, nothing written. The read-only +procedure, recorded because the next host bump may genuinely need it: the migrations table is +`_emdash_migrations` (with `_emdash_migrations_lock`), the staging binding is `DB`, the real database +name lives in the gitignored `sites/staging/wrangler.local.jsonc`, and the check is +`wrangler d1 execute --remote --command "SELECT name FROM _emdash_migrations ORDER BY name"`, +compared against the new build's `MIGRATION_NAMES` **by name, never by count**. + +### The overrides went away entirely rather than moving to the release + +All four `file:` overrides in `pnpm-workspace.yaml` were **deleted, not repointed**, because every +reason they existed is gone at `0.38.0`: + +- `@emdash-cms/admin@0.38.0` **does** export `./portable-text-table`, the subpath whose absence at + `0.37.0` forced the admin package to be vendored alongside the core. +- `@emdash-cms/registry-client@0.6.0` **does** export `./listing-policy`, likewise. +- The quiet one, `@emdash-cms/cloudflare`, still pins `emdash` **exactly** — but it now pins + `0.38.0`, which is the version the manifests themselves name, so the exact pin and the manifest + agree and a single copy resolves with no help. Verified: one `emdash@0.38.0` directory in + `node_modules/.pnpm`, one `emdash@0.38.0` key in the lockfile. + +The one-copy outcome is therefore a *coincidence of agreement* rather than something forced, which +is exactly why `sites/staging/test/host-pin.test.ts` was **kept and updated rather than deleted**. If +a future `@emdash-cms/cloudflare` pins an `emdash` other than the one the manifests name, a second +copy returns and the Worker bridge silently binds to the host **without** the primitives; that test +is what makes it loud, and the remedy is to reintroduce an exact `emdash` override. + +`minimumReleaseAgeExclude` grew rather than shrank: the four packages used to be absent from it +because `file:` tarballs bypass the release-age check entirely. They resolve from the registry +again, so the whole 0.38 train is listed now. + +### Results on the released build + +Full battery green, run from the worktree root on the released install: + +| Gate | Result | +|---|---| +| `pnpm lint` (incl. the domain-purity dep check) | clean, 1361 modules / 2979 dependencies cruised | +| `pnpm typecheck` | clean | +| `pnpm -r build` | all 9 projects, staging Astro/Worker build included | +| `pnpm test` | **224 files passed**, 17 skipped; 4348 passed, 820 skipped, 14 todo | +| `pnpm test:pg` (Postgres, `127.0.0.1:55432`) | **60 files passed**; 1551 passed, 7 skipped | +| `pnpm test:d1` — **T3, the production dialect** | **14 files passed**; **525 passed, 0 skipped** | +| `pnpm test:e2e` | 13 passed, 21 skipped (the browser-driven specs, which gate on a running site) | + +### One pre-existing failure INC-D6 uncovered and fixed + +`pnpm test:e2e` was **already red on the integration branch before this increment touched +anything** — `sites/staging/e2e/harness.spec.ts`'s ADR-0006 additive gate, which asserts the set of +skip-shaped constructs in the sandbox suites **exactly**.

Without it, importing the root `emdash` entry threw `SyntaxError: … does not provide an export named 'isProvenFirstRelease'`. | + +Every other sibling (`@emdash-cms/auth`, `blocks`, `gutenberg-to-portable-text`, `plugin-types`, +`registry-lexicons`, `registry-moderation`, `registry-verification`) matched its published release +and resolved from the registry normally. + +**The generalisable lesson, worth keeping past the vendoring:** the host monorepo's workspace +packages can carry source newer than the release their `package.json` version names, and the core +build links against the workspace copy. Any sibling whose unreleased source the core reaches has to +be vendored alongside it. Importing the root `emdash` entry is the cheap way to find them — a missing +one surfaces as an unresolved named import at module-instantiation time, not at install time. Both +gaps closed at `0.38.0` / `0.6.0`, which is why the overrides could be dropped outright. + +### Why the overrides were load-bearing + +Two failed loudly, one quietly. The loud pair were `emdash` and `@emdash-cms/admin`: the tarballs +cross-pinned each other at `0.37.1-otta.1` / `0.5.1-otta.1`, versions that do not exist on the +registry, so dropping either left a specifier nothing could satisfy and the install stopped. The +quiet one was `@emdash-cms/cloudflare`: the published `0.37.0` depended on an **exact** `emdash` +version the registry *could* satisfy, so without its override a second, stock `emdash` landed in the +store and the Worker bridge bound to the copy **without** the primitives — no install error, no type +error, just missing methods at runtime. That is the failure mode the one-copy assertion exists for, +and `sites/staging/test/host-pin.test.ts` still asserts it. + +The overrides had to live in `pnpm-workspace.yaml`: **pnpm 11 ignores `pnpm.overrides` in +`package.json` without warning.** The pins had to never float — no `^`, no `~`: a stray `emdash@1.0.0` +exists on npm and is **not** the latest release of this host. Package manifests kept plain `"0.37.0"` +specifiers throughout, which is what made INC-D6 an override edit plus a three-manifest version bump +rather than a sweep. + +### The conflict resolutions in the merge + +Both sides added methods to the same storage surfaces, so almost every conflict was "keep both". +`vendor/otta-emdash-cas.diff` was the machine-readable record — `git diff -- +packages/` — so `git apply --check` against a future base answered "do the recorded resolutions still +apply?" without a clone. + +1. **The migration-number collision — the load-bearing one.** #2980 added + `076_plugin_storage_revisions`; the base already ended at `076_collection_nav_group`. Renumbered + to **`077_plugin_storage_revisions`** — the file, its three `.ts` importers, and the runner's + import alias and map key. (Upstream shipped the same number. See §5.) +2. **Type re-exports** (core's root and plugin entries, and the plugin-storage repository): keep both + sides' exported type names. +3. **The sandbox bridge protocol, host implementation and in-sandbox wrapper**, for both the + Cloudflare and workerd runtimes: keep both sides' operations. +4. **The migrations integration test**: take #2980's form, which slices the runner's exported + migration-name list instead of restating the tail by hand, so it needs no edit when a migration is + added. +5. **The workerd integration test**: keep both sides' cases as **two separate tests**. A textual + "keep both" interleaves them into one broken block, because both sides add a case in the same + place with the same surrounding shape. +6. **The base's D1 `updateIf` test** builds its storage table by hand and needed the `revision` + column the merged repository writes on every write — one added column, matching what #2980 did to + its own fixtures. +7. **The storage documentation page**: keep both sections. +8. **One post-merge fix-up, not a conflict resolution.** The keep-both on the Cloudflare sandbox + bridge's `import type … from "emdash"` list left a `NumericDelta` import neither parent uses, and + the host lints with `oxlint --type-aware --deny-warnings`, so the merge commit itself did not lint + even though both of its parents did. The fix was the one commit on top of the merge — which is why + the build recorded a **branch head** as well as a merge commit. + +### Node and wrangler + +`engines.node: ">=22.16"` is the host's own floor, and the rule the repo settled on is: the root +manifest declares it, and so does every manifest that resolves the host (`sites/staging`, +`packages/admin-react`); no other package restates it, and CI pins the major line only +(`node-version: "22"`), which satisfies the floor without narrowing to one minor. The `wrangler` +catalog entry moved `^4.68` → `^4.99` because `@emdash-cms/cloudflare` declares +`peerDependencies.wrangler >= 4.99.0` — still true at `0.38.0`, so the catalog entry stays. + +### Build evidence, as recorded at the time + +On the vendored base: the host's own storage, conditional-write, no-oversell and migration suites +passed on SQLite and Postgres, its Worker-runtime sandbox suites passed, and a throwaway consumer +confirmed the migrations applied with `077_plugin_storage_revisions` as the tail and that all four +primitives behaved as documented, stale-revision refusals included. + +One upstream test is worth naming because it is **sometimes red and should be discounted**: +`@emdash-cms/cloudflare`'s `tests/db/d1-migration-target.test.ts` — "uses project-local Wrangler and +preserves account inheritance for a named environment" — spawns a real `wrangler` process and times +out against the suite's 5s default on a loaded machine.

It does + * NOT verify the signature, it holds no webhook secret, and it makes no + * accept/reject decision of its own beyond "this request is not even shaped + * like a Stripe delivery". + * + * So the properties worth pinning here are transport properties, and each group + * below is one of them: + * + * - **bytes** — a Stripe HMAC is computed over the EXACT delivered bytes. If + * this endpoint ever parsed and re-serialized the body, every signature + * would fail and every real payment would stop settling. The base64 must + * round-trip byte-for-byte, non-ASCII and whitespace included. + * - **the token** — provisioned ⇒ attached; unprovisioned ⇒ the request is + * still forwarded with no header at all, because the plugin's gate is + * pass-through-when-unset (mirroring `service/src/auth.ts`) and the HMAC is + * the real trust anchor. Sending an EMPTY header instead would be a + * behaviour change, not a no-op: the plugin's gate distinguishes "header + * absent" (reject when a token IS configured) from "header present". + * - **the status** — EmDash's route framework wraps every handler return in + * `{success, data}` at HTTP 200, and Stripe's retry logic keys on the HTTP + * STATUS. The plugin therefore returns the status it WANTS as a field and + * this endpoint replays it. A 401 that arrived as a 200 would tell Stripe a + * rejected delivery had succeeded and stop the retries forever. + * - **the gate** — an anonymous POST straight at this public URL, with a + * forged body and a wrong/absent token, must come back rejected. This is the + * test that replaced the original design's "routing test": there is no + * authenticated path into this endpoint to test, because a webhook is always + * unauthenticated. + * - **the dispatcher** — PUBLIC, never private. `handlePluginApiRoute` takes a + * caller identity a webhook structurally cannot supply, and EmDash binds it + * only on the authenticated path. A context carrying only the private + * dispatcher must fail closed, not fall back to it. + * + * The dispatcher fake below mirrors the real plugin route's OBSERVABLE contract + * (the `StripeWebhookSettleResult` union and its statuses), not its internals — + * the route's own suite, `packages/plugin/test/stripe-settle-route.test.ts`, + * drives the real HMAC against a real store. + */ +import { afterEach, describe, expect, test } from "vitest"; +import type { APIContext } from "astro"; +import { + createStripeWebhookSettleHandler, + STRIPE_WEBHOOK_SETTLE_ROUTE, + WEBHOOK_EDGE_TOKEN_HEADER, + WEBHOOK_EDGE_TOKEN_KEY, + type StripeWebhookSettleResult, +} from "@otta-sh/plugin"; +// The stub `vitest.config.ts` aliases `virtual:emdash/env` to.
