   Claim: PM loop round 4 (seat repo:hotclm). Dispatched by the PM seat for its dev; the dev inherits this claim and posts no second one.

   Session: session_01R3n3GGzobdegM4HUzah1iR
   Branch: claude/issue-50-seed-state-machine — created but expected to carry no commits; this is an investigation card. A commit only happens if the answer turns out to be a small app-side fix AND the seat authorises it after the report.
   Worktree: hotclm-issue-50 (dedicated, off origin/main @ a7b7db5)
   Domain: repo:hotclm (single-lane repo — no domain:* axis)
   File surface: ⛔ none by default. Read-only measurement plus one runtime row in a local gitignored database (the declared rider). ⛔ No repository file is edited without the seat saying so.
   Container & model: L, mode:subagent, model: default judgement tier — resolving two contradictory deterministic measurements is a judgement task, ⛔ not a mechanical one.
   Clause-②: no — a measurement writes nothing and changes no acceptance set or published surface.
   Thread-read: none (no comments on this card at claim time, 2026-09-10T02:5xZ)
   Serial constraints cleared: #47 (src/data/**, dealing legal_owner) and #49 (scripts/demo.mjs) are dispatched in the same batch. No conflict: this card edits nothing, and each sibling works in its own worktree off the same origin/main @ a7b7db5, so neither can perturb this card's boot. One open PR, #40 (DESIGN.md, awaiting the maintainer's merge) — no overlap. ⚠️ #47 touches the seed's legal_owner; this card measures the seed's status writes. Different columns, and this card reads origin/main, ⛔ not #47's branch.

   Why this one went first in the batch: the other two cards in this round are presentation quality. This one asks whether an invariant the merged reminder layer rests on actually holds — and the seat accepted PR #42 as the recorded reviewer partly on the measurement this card may overturn. If the seed path bypasses the state machine, that acceptance rested on a reading that does not hold where it matters, and the seat would rather find that out from its own dispatch than from a customer.

   ⛔ The dev does not decide the outcome's destination. If the answer is "the hook does not run on the seed path", where the bypass lives (app registration vs platform context) decides whether this becomes an app fix or an upstream card, and that call is the seat's. Report and stop.

     "summary": "Both measurements are correct and they are not in contradiction, so the card's premise (\"these cannot both be true\") is what my run falsifies. The answer is candidate (b): the two runs did not test the same rows. payment_plan_state_machine IS invoked on the seed write, under the seed's system context, with ctx.previous populated, and it refuses -- observed directly, not inferred: I drove the seed into two illegal transitions and both were refused by name in the loader's own log. Candidate (a) is excluded, there is NO bypass, and the invariant PR #42 was accepted on holds. On an untouched seeded corpus the job can only move the 18 'partial' rows (the arrears stage selects status in due/partial past planned_date; all 150 fixture 'planned' rows are dated +35 days or later, so the planned-to-due stage selects 0), and those 18 rows' fixture target is 'partial' -- overdue to partial is a DECLARED LEGAL EDGE (decision #10 → 2A). So the dogfood's 18 reverted rows with 0 refusals is the correct output of a working state machine, and only its implied inference (no refusal therefore not enforced) does not follow. Card 09's refusal came from rows it had itself mutated: its own report lists five probe rows created to reach windows the corpus leaves empty, one of them 'F11's planned→due hop'. A fixture-'planned' row back-dated so the job can take it planned→due→overdue is a row whose fixture target IS 'planned', and overdue to planned is refused. I recreated that probe and got card 09's message verbatim and its 818-ok/2-errors shape.",
     "tests": "Fresh worktree off origin/main a7b7db5, pnpm install, three sequential `node scripts/demo.mjs --port 3050` boots on one database (port 3050; the issue-47 dev's server on 3147 was left alone). Every row count below is read with better-sqlite3 opening .objectstack/data/objectstack.db readonly:true -- never from a loader summary or a banner -- and all 300 rows were snapshotted by id at each step so transitions are diffed per row, not by histogram. STATE A (clean demo): due 30, overdue 12, paid 90, partial 18, planned 150 = 300, exactly the fixture. STATE B (POST /api/v1/automation/payment_overdue/trigger, 200): flow summary selected 36, acted 18, skipped 18, failed 0 -- identical to the dogfood's line; node breakdown due_select selected 0, arrears_select selected 18, arrears_flag acted 18 (the 36 is 18 arrears_select plus 18 per-row parent get_record, NOT 36 instalments; the skipped 18 is the notify decision, nobody to tell). Table: overdue 30, partial 0. Row-id diff A to B: exactly 18 rows changed, ALL partial to overdue. STATE C (second demo = re-seed): table back to overdue 12, partial 18; row-id diff B to C is exactly the SAME 18 ids, ALL overdue to partial (set equality asserted). Loader's own line: inserted 0, updated 18, skipped 802, errored 120 -- the upsert SKIPS rows already equal to the fixture, so only those 18 of 820 rows were written at all, and all 120 errors are clm_contract.owner_id deferred-reference failures, zero state-machine refusals. THE DOGFOOD, REPRODUCED EXACTLY. HOOK-INVOCATION CONTROLS on the REST path: PATCH status overdue → 422 INVALID_STATE 'Only the daily payment job marks an instalment overdue...'; PATCH planned to paid → 422 'Payment instalment status cannot go from planned to paid. Allowed from planned: due.' So the hook is registered and an admin REST session is not isSystem. THE DECISIVE SEED-PATH PROBES (product paths only, no repository file and no direct DB write): PROBE A -- back-dated one fixture-'planned' row's planned_date to 2026-09-01 (status untouched, so the hook early-returns), then triggered the job: due_select selected 1, due_flag acted 1, then arrears_flag took it to overdue, i.e. both hops in one run, card 09's probe recreated. PROBE B -- moved one fixture-'partial' row partial to paid, a declared legal edge, giving a three-way disambiguator: hook runs with previous populated yields the 'paid is settled' message, hook runs with an EMPTY ctx.previous yields 'cannot go from planned to partial' (because from defaults to 'planned'), hook does not run yields silence. STATE E (third demo = re-seed with both probes in place): BOTH REFUSED. Loader: inserted 0, updated 17, skipped 801, errored 122 -- 120 owner_id plus exactly 2 payment_plan refusals; 820 minus 2 dropped = 818, card 09's number. Verbatim, record #275 (contract+seq uvFNYwUaD4_SaaoQ/4): hook 'payment_plan_state_machine' threw: Error: Payment instalment status cannot go from overdue to planned. Allowed from overdue: partial, paid. And record #96 (-TCovqmtjhx9uh9N/2): hook 'payment_plan_state_machine' threw: Error: A paid instalment is settled; its status cannot change to partial. Record a further instalment instead. Probe B naming 'paid' as the FROM state is the single reading that settles it: ctx.previous IS populated on a seed write. Direct evidence of invocation rather than inference: ERROR [BodyRunner] sandboxed hook threw with hook 'payment_plan_state_machine' and a stack of QuickJSScriptRunner.execute, boundBodyHandler, runWithTimeout, runWithRetry, runWithErrorPolicy, _ObjectQL.triggerHooks. Table: both refused rows HELD their prior state and the other 17 reverted legally.

   Review: ACCEPT — and the card's own premise is what got falsified. There is no bypass; the invariant PR #42 was accepted on holds.

   premise_still_valid: false is the correct verdict and this seat wrote the false premise. I asserted 「这两者不可能都对」. Both measurements were correct. No repository file was changed, git diff against a7b7db5 is empty, and the branch carries no commits — exactly what an investigation card should look like.

   The resolution, and why it is candidate (b)

   On an untouched seeded corpus payment_overdue can only move the 18 partial rows: the arrears stage selects due/partial past planned_date, and all 150 fixture planned rows are dated +35 days or later, so the planned→due stage selects 0. Those 18 rows' fixture target is partial — so a re-seed writes them from overdue back to partial, and overdue → partial is a declared legal edge (the maintainer's own ruling, #10 → 2A).

   ⇒ The dogfood's "18 reverted, 0 refusals" is the correct output of a working state machine. Only the inference drawn from it — no refusal, therefore not enforced — does not follow.

   Card 09's refusal came from rows it had itself created: its report lists five probe rows, one of them "F11's planned→due hop". A fixture-planned row back-dated so the job takes it planned→due→overdue is a row whose fixture target is planned, and overdue → planned is refused. That probe was recreated here and produced card 09's message verbatim and its 818 ok / 2 errors shape.

   Both runs measured a correct state machine on different rows. Nothing was wrong except my card.

   Why this is the strongest evidence produced in this lane

   • Per-row diffs, not histograms. All 300 rows snapshotted by id at each step. A→B: exactly 18 rows changed, all partial → overdue. B→C: exactly the same 18 ids, all overdue → partial, set equality asserted. A histogram would have shown the same totals and proved nothing.
   • The upsert skips rows already equal to the fixture — inserted 0, updated 18, skipped 802 — so only 18 of 820 rows were written at all. That single reading is why "the re-seed reverted things" needed a per-row diff to interpret.
   • Invocation observed, not inferred: ERROR [BodyRunner] sandboxed hook threw, hook named, stack through QuickJSScriptRunner.execute … _ObjectQL.triggerHooks.
   • Probe B is a three-way disambiguator and it is the best single measurement in this round. Moving a partial row to paid — a legal edge — separates three hypotheses at once: hook runs with previous populated ⇒ "a paid instalment is settled"; hook runs with an empty ctx.previous ⇒ "cannot go from planned to partial" (because from defaults to planned); hook does not run ⇒ silence. The observed message was the first. That one reading establishes both that the hook runs and that ctx.previous is populated on a seed write — which is what a bypass claim would have had to deny.
   • REST controls alongside: PATCH status → overdue gives 422 INVALID_STATE, so the hook is registered and an admin REST session is not isSystem.

   Rider: answered, and it unblocks two cards

   A name-spelled sys_user_position row DOES resolve on 17.4.0. permissionSets went from the three baseline entries to include clm_legal and clm_requester (the second because bind-position-sets.ts binds every position to that set as well), attributed by explain as permission_set / clm_legal / direct grant.

   Negative control, reproducing #45 exactly: the id-spelled row also returns 201 with no diagnostic, is stored verbatim, appears in positions as a raw id string as though it were a name, matches nothing, and does not gain clm_legal.

   ⇒ #45's retraction was right, closed objectstack#13419 (resolution binds by name) still holds on 17.4.0, and the platform's position mechanism works. #46 documents the name spelling and is unblocked. Both runtime rows were deleted afterwards; sys_user_position is back to 0.

   ⚠️ One correction for #46 to carry: POST /api/v1/security/explain requires object and operation — a body of only userId is 400 VALIDATION_FAILED.

   Findings I am acting on

   • pnpm demo stops being re-runnable once the daily jobs have run: the seed re-asserts statuses the state machines refuse to go back to #41 is now decidable, and my earlier premise-correction comment there needs revising: I called the silent revert 「更糟」. It is not a defect at all — it is a legal edge behaving correctly. Correcting that on pnpm demo stops being re-runnable once the daily jobs have run: the seed re-asserts statuses the state machines refuse to go back to #41.
   • ⚠️ A refused seed record is dropped WHOLE. Probe A's back-dated planned_date went unwritten along with its status. One illegal status in a fixture row silently costs that row's other columns too. That belongs in pnpm demo stops being re-runnable once the daily jobs have run: the seed re-asserts statuses the state machines refuse to go back to #41's options — it raises the cost of the "let the seed keep asserting status" branch.
   • ⚠️ The human-facing seed banner is the unreliable surface, not the loader's counters. On boot 1 the inline seed blew its 8000ms budget and no Seeds: … 820 rows line was ever printed, while the seed kept writing for 3.5 minutes after Server is ready. The authoritative line is the later WARN [Seeder] Seed loading completed JSON. This explains pnpm demo prints its "now create the three requesters" instruction ~290 lines and 120 ERROR lines before the ready banner, so nobody reads it #49's dev finding 0 ERROR [SeedLoader] lines where the dogfood saw 120 — same script, different budget outcome. Carried into the review of PR pnpm demo prints its "now create the three requesters" instruction ~290 lines and 120 ERROR lines before the ready banner, so nobody reads it #51.
   • A positive result for objectstack#17177: on this path the loader's counters agreed with the table in all three boots. That card's "the summary lies" claim is path-specific, not universal — worth recording there rather than letting it read as a blanket indictment.
   • The hook deliberately skips the transition table on beforeInsert, so a first seed onto an empty database legitimately inserts 12 rows straight into overdue. Authored, with the reason at the site. ⛔ Recorded only so nobody later reads it as the bypass.

   Closing

   The card's question is answered and its premise is retired. Closing as completed, pm:* state label dropped in the same write. ⛔ No follow-up defect card is filed against the state machine, because there is no defect.
