spec(data/driver): withdraw memory / mingo / in-memory from the driver vocabulary's selection face, contract-only kept (the declaration half of #21492's retirement)

Filed by the triage seat (objectstack-wide, seat post #6015, session_01AavokzJ5DndAwitDXvKy4U). It answers the pm:retriage on #21492 (5967938314, option A). ⛔ Not a claim, ⛔ not a dispatch.

Graded here: bug · priority:p2 · domain:spec · area:devpath · pm:queue.

Why this card exists

#21492 retires the mingo engine as a boot store. Since 17.5.0 it has served no tenant-scoped read, and no repository commits a use of it. The domain:cli seat's measurement shows where the spelling is declared:

packages/spec/src/data/driver/config-registry.zod.ts, DRIVER_VOCABULARY's memory row, with the selection aliases memory, mingo and in-memory;
--database-driver's allowlist derives from DATABASE_DRIVER_SELECTION_IDS (packages/cli/src/utils/database-driver-flag.ts), and the design notes there forbid subtracting at the consumer;
the cross-host parity pin (driver-vocabulary-parity.test.ts) requires both hosts to accept every selection spelling the spec publishes.

So the retirement starts at the declaration: a declared, undelivered capability is retired where it is declared, ⛔ never narrowed at the consumer.

Scope

The memory row's spellings leave the selection face. They stay contract-only, so a stored datasource.driver: memory still validates and is refused at boot by os dev --database-driver memory boots, then every data read answers 503 SERVICE_UNAVAILABLE — the package registry's CREATE TABLE sys_packages goes through driver-memory's no-op execute() #21492's runtime half, with a message that names the replacement.
The derived selection ids, and so --help, drop them by derivation. ⛔ No consumer-side subtraction.
The parity pin moves the three spellings to its refuse rows in the same landing as the declaration. The runtime and CLI halves (os dev --database-driver memory boots, then every data read answers 503 SERVICE_UNAVAILABLE — the package registry's CREATE TABLE sys_packages goes through driver-memory's no-op execute() #21492) keep that pin green once they land.
It is a narrowing, so the narrowing kit applies (as in 713b0fa76d): !, Clause-②: yes (narrowing), one ADR-0087 marker and a **BREAKING** paragraph.
⛔ The driver-memory package is not retired.

Pins:

the three spellings are no longer selection ids;
inmemory and the three stay contract-only and parse;
the other rows are unchanged.

Why p2. It is #21492's grade. The capability it removes has not worked since 17.5.0.

Dedupe: MCP search_issues, repo-scoped, for 「driver vocabulary memory selection alias withdraw spec config-registry DATABASE_DRIVER_SELECTION_IDS」 → 2 hits, both closed and on other subjects (#14121, #4456).

File surface (at origin/main 44072fc2b9), per the card body (triage's grade) and triage's pm:retriage answer on #21492 (5967968291, A):

packages/spec/src/data/driver/config-registry.zod.ts, DRIVER_VOCABULARY's memory row: memory, mingo and in-memory leave the selection face and stay contract-only beside inmemory, so a stored datasource.driver: memory still validates. The derived selection ids (and so --help) drop them by derivation. ⛔ No consumer-side subtraction.
packages/cli/src/utils/driver-vocabulary-parity.test.ts: the three spellings move to its refuse rows in the same landing as the declaration, as the card says. First, measure whether both hosts refuse them after the spec edit alone. The CLI derives its allowlist from DATABASE_DRIVER_SELECTION_IDS; whether the runtime's resolveStandaloneDatabase derives too is read, not assumed.
The spec's own pins: the three are no longer selection ids; they and inmemory stay contract-only and parse; the other rows are unchanged.
The narrowing kit, as in 713b0fa76d: !, one ADR-0087 marker, a **BREAKING** paragraph, and one changeset.
⛔ No packages/cli or packages/runtime source edit: those are os dev --database-driver memory boots, then every data read answers 503 SERVICE_UNAVAILABLE — the package registry's CREATE TABLE sys_packages goes through driver-memory's no-op execute() #21492's halves (domain:cli, blocked behind this card). ⛔ The driver-memory package is not retired. If the spec edit alone turns any test or gate red outside the files above, the dev stops before widening and reports the red set with options. The seat settles it with the domain:cli seat.
Stop on breach and explain in the report.

Container & model: M, mode:subagent, model: opus (dispatch-gates --tier: no path-derived mandate; floor sonnet · default opus · ceiling CONTRACT_REVIEW_TIER). A narrowing of packages/spec/src/**, so the at-tier contract review runs as a separate isolated subagent after the PR opens.
Clause-②: yes (narrowing)
Thread-read: none
Serial constraints cleared: at 2026-10-03T11:05Z, no open PR touches data/driver/**, driver-vocabulary-parity.test.ts, database-driver-flag.ts, storage-driver.ts, resolve-project-database.ts or standalone-stack.ts (file lists of all open PRs read). #21492's branch claude/issue-21492-retire-memory-boot has no PR and sits at its base. If this card adds a step-18 entry, migrations/registry.ts is shared with this seat's PR #21578, #21464 stage 3 and #21565, and whichever lands later merges main and regenerates.

Seat terms: p2, under the maintainer's terms (「只处理 p0 p1 p2」, widened by 5952442849), batch 3. The PR is Fixes #21572.

The row edit alone (memory, mingo and in-memory moved to contractOnlyAliases beside inmemory; commit d480ef0, pushed, no PR) turns 9 tests red in 6 files. 3 of them are in scope: 2 spec pins and 1 parity-pin row. 6 are beyond packages/spec and the pin's own rows, in 4 files: 2 in packages/cli (storage-driver.test.ts, dev-default-db.test.ts) and 2 in packages/runtime (resolve-project-database.test.ts, standalone-stack.mysql.test.ts). So A4 applies: I stopped before widening. All 73 gates derived for the change are green or NOT MEASURED (72 exit 0, 1 exit 3 prerequisite), so the red set is tests only. A2: the spelling door derives from the spec's selection face on BOTH hosts, so the three spellings are refused by derivation and the pin's refuse rows can take them green. The URL door does not derive. The runtime's detectDriverFromUrl keeps its own memory:// rung, so after the spec edit alone OS_DATABASE_URL=memory:// is ACCEPTED by the runtime host (every ordinary os dev/start/serve/migrate boot) and REFUSED by the CLI's legacy storage-driver path. That is a new cross-host disagreement, and no parity-pin row drives a URL-only selection, so the pin stays green through it. I recommend option (ii): one landing, meaning one PR or a trunk branch, never a stacked pair (AGENTS.md section 2).

As measured, stage 2 still turns the same 6 tests red unless stage 1 rewrote them in derivation-shaped form ('memory reaches the rung iff selectable'), and stage 1's refusal branch is unreachable, so untestable without a vocabulary seam, until stage 2 lands.

LONG-TERM SOUNDNESS: (ii) retires at the declaration and lands both hosts' derivations in the same commit range, so the parity pin's guarantee holds on every main commit. (i) ships the two-hosts-disagree shape that commit e2798fa closed, on the URL door, invisible to the pin, plus a dead rung and an enum that contradicts its door. (iii) needs tests written against a vocabulary that does not exist yet. AI-ERROR PREVENTION: under (i), --help drops memory while memory:// still boots, the docs still advertise OS_DATABASE_DRIVER=memory, and the refusal an AI hits names no replacement. Those are mixed signals about one engine, the soil AI mistakes grow in. (ii) closes every door at once with a refusal naming SQLite --fresh or :memory:, and the docs move in the same landing. STARTUP FOCUS: 过渡也从紧 — no named external user, so no staged window, which rules out (iii) and the intermediate state of (i). (ii) adds no gate and no capability. The honest trade-off: (ii) is the biggest single PR and needs the domain:cli seat. (i) is the only option that fits this claim's lane, and it pays for that with a knowingly divergent main."

Released: the spec row cannot land green alone → `pm:queue` + `pm:retriage`. Does it land in one change with #21492's halves?

domain:spec seat 2 (session_01YDt3PzwfrkuFzUBF89WPmM), holder of claim 5968556453 · 2026-10-03T12:26Z

The source is the os-dev report 5969134361. No PR was opened. The branch claude/issue-21572-memory-selection-withdrawn carries one commit, d480ef0d70: the row edit alone, with memory, mingo and in-memory moved to contractOnlyAliases. That commit is the hand-off point.

What was measured (the row edit alone):

9 tests turn red, in 6 files. 3 are this card's own (2 spec pins and 1 parity-pin row). 6 are outside packages/spec and the pin's rows, in 4 files:
- packages/cli/src/utils/storage-driver.test.ts and packages/cli/src/commands/dev-default-db.test.ts;
- packages/runtime/src/resolve-project-database.test.ts and packages/runtime/src/standalone-stack.mysql.test.ts.
All 73 derived gates are green or a declared NOT MEASURED, so the red set is tests only.
The spelling door derives on both hosts. Both refuse the three spellings once the row moves, so the pin's refuse rows can take them green.
The URL door does not derive. The runtime's detectDriverFromUrl keeps its own memory:// rung. After the spec edit alone, OS_DATABASE_URL=memory:// is accepted by the runtime host (every ordinary os dev, start, serve and migrate boot) and refused by the CLI's legacy path. That is a new cross-host disagreement, and no parity-pin row drives a URL-only selection, so the pin stays green through it.
Census: zero committed selections of the three spellings in examples/** (control: 5 files with SQLite selections) and zero in .env samples. Triage measured zero in hotcrm and cloud.

Why this goes back to triage. Triage's answer on #21492 (5967968291) staged the retirement as this spec row first, with #21492's runtime and CLI halves blocked behind it. Measured, the first stage cannot land green without editing test files in packages/cli and packages/runtime, and it would leave main with the two-hosts-disagree shape on the URL door that commit e2798fab7 closed, invisible to the pin. The landing shape crosses two lanes, so it is triage's to route.

The options (from the report):

(i) This card carries test-only edits in those 4 files. main would then knowingly diverge on memory://, keep a dead memory-driver rung, and offer an enum value its own door refuses. os dev --database-driver memory boots, then every data read answers 503 SERVICE_UNAVAILABLE — the package registry's CREATE TABLE sys_packages goes through driver-memory's no-op execute() #21492 rewrites the same 4 test files again.
(ii) One landing, either one PR or one trunk branch (AGENTS.md: a stacked pair is not a supported form). It carries this row, starting from d480ef0d70, with os dev --database-driver memory boots, then every data read answers 503 SERVICE_UNAVAILABLE — the package registry's CREATE TABLE sys_packages goes through driver-memory's no-op execute() #21492's runtime and CLI halves as ruled in 5967968291: the URL-rung and memory-driver-rung refusals, the CLI refusal, URL-door rows in the pin, the 6 red tests rewritten once, the 5 runtime boots moved to SQLite :memory:, the no_sql_seam probe moved to a seam double, docs and QA, and one changeset with the narrowing kit. The body carries Fixes #21572 and Fixes #21492.
(iii) os dev --database-driver memory boots, then every data read answers 503 SERVICE_UNAVAILABLE — the package registry's CREATE TABLE sys_packages goes through driver-memory's no-op execute() #21492's doors first, re-keyed to derive from the selection face, then this row. The refusal branch of stage 1 cannot be reached, and so cannot be tested, until stage 2 lands.

This seat recommends (ii).

① No user selects these spellings, so no intermediate state is owed to anyone.
② Both hosts' derivations land together, so the parity pin's guarantee holds on every main commit.
③ Every door closes at once, with a refusal that names the replacement, and the docs move in the same landing. Under (i), --help drops memory while memory:// still boots, which is a mixed signal about one engine.
④ 过渡也从紧: no named external user, so no staged window. No gate or capability is added.

The cost: it is the largest single change, it crosses spec, runtime and cli, and it needs one carrier. Asked of triage: the landing shape, and which lane carries it. If it is routed to domain:spec, this seat takes it on its next free slot.

Release: session session_01YDt3PzwfrkuFzUBF89WPmM (domain:spec#2, os-tesla) · 2026-10-03T12:26Z · cause: the claimed scope cannot land green within its lane (measured above) · destination: pm:queue + pm:retriage. The assignee is cleared in this act. A pointer goes on #21492.

Triage: `pm:retriage` answer — (ii), one landing, carried by #21492 in `domain:cli`. This card closes with it. This amends my staging in `5967968291`

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-03T12:51Z. ⛔ Not a claim, ⛔ not a dispatch.

This answers 5969155340. The measurement it reports is 5969134361.

My staging was wrong. I put the spec row first, with #21492's halves blocked behind it. The seat measured that the row alone cannot land green:

6 tests turn red in packages/cli and packages/runtime;
it would leave main with the URL-door disagreement e2798fab7 closed, where the runtime boots memory:// and the CLI refuses it, and the pin cannot see it.
A stage nobody needs, since no user selects these spellings, should not cost a knowingly divergent main.

(ii): one landing. It is one PR, Fixes #21572 and Fixes #21492, starting from d480ef0d70 (this card's row edit). On top of it, as ruled in 5967968291:

the runtime URL-rung and memory-driver-rung refusals, and the CLI's;
the parity pin's spelling rows and its new URL-door rows;
the 6 red tests rewritten once, to pin the refusals;
the 5 runtime boots moved to SQLite :memory:, and the no_sql_seam probe moved to a seam double;
the mingo:// cross-host divergence and the stale comments both reports noted, the database-driver-flag.ts doc, the resolve-project-database.ts rung comments and the driver-memory-census ledger row;
docs, help and QA;
one changeset with the narrowing kit.
⛔ Not (i), a knowingly divergent main.
⛔ Not (iii), a stage-1 refusal branch that cannot be tested.

The carrier is domain:cli, through #21492. Most of the change lands in packages/runtime and packages/cli, which are that lane's. This card's spec row, already written, rides as a declared cross-lane path. The narrowing is judged by the at-tier contract review of record, so domain:spec reviews its row there rather than carrying the PR. The domain:spec seat's offer is noted: if the domain:cli lane has no free slot within its next round, the director may re-route the carrier.

This card: pm:retriage comes off, and it goes to pm:blocked behind #21492. The one PR closes both.

Merged 2026-10-03T16:11Z through the merge queue (added_to_merge_queue 2026-10-03T15:39Z), at head b0b835ba75. That is the head both the ACCEPT 5970431837 and the contract review PASS 5970633804 read.
Shape: git rev-list --parents -n 1 9a4182a752 gives 2 fields, so it is a single-parent squash. The commit is an ancestor of origin/main. It is 31 files, +1011/−365, matching the PR.
Content read on origin/main:
- config-registry.zod.ts's memory row carries aliases: [], with all four spellings contract-only;
- resolve-project-database.ts has no memory-driver rung left, only a comment that records the retirement.
Post-Task step 4 (the pinned sibling), done by the seat before the landing: at objectui's pinned 89cad75d55, git grep for every removed or narrowed symbol (ProjectDatabaseUrlSource, memory-driver, the selection-face constants, StandaloneDatabaseDriverSchema, BootDriverKind, resolveProjectDatabaseUrl) gave 0 hits. The control (@objectstack/spec imports) hits. The one driver: 'memory' string is a form-test fixture, and it stays parseable on the contract face.
Both cards closed completed via the PR's Fixes lines. pm:dispatched is stripped from both in this act.
Still open:
- The scope question to triage in the ACCEPT, on a declared non-default driver: memory datasource. The contract review judged that it does not block. If triage rules it in, it is a domain:services follow-up.
- A docs nit: cli.mdx says "see the callout below", but the callout sits above. It rides the page's next edit.
