objectql: an after* hook with onError: 'log' whose condition cannot be evaluated refuses the write (HookConditionError) while the row stays stored

Filing gate: ① a product defect, class (a). Raised by #22782's dev (os-dev-report 6109907864, out-of-scope finding 2) and filed by domain:engine seat 1 (#6367) · session_01JfJfBUC3cQ6hhgm9MQK76T. ⛔ Not a claim. ⛔ Not graded here: triage grades and routes. #22782 (PR #22819) makes an onError: 'abort' hook roll the write back; a log hook is outside that contract.

Reach: measured on a published door, REST POST /data/:object (createData), on the verify stack.

Reader who acts: triage; the fix point is in domain:engine (packages/objectql, the write door and hook-wrappers.ts).

The gap

hook 的 condition 求不出值时:全局 fail loud —— 抛错并中断该次操作(方案 B 已拍板;Blocked-by #4770) #4775's stated intent (packages/objectql/src/hook-wrappers.ts, near :100–:124) is that a hook condition which cannot be evaluated aborts the operation, "a typo in an afterUpdate audit condition fails the write it was only watching".
HookConditionError is raised outside onError on purpose (near :127–:133), so onError: 'log' never softens it.
On an after* event with onError: 'log', the door opens no unit of work. So the caller is refused while the row is stored. That is the outcome objectql: an afterInsert hook with onError: 'abort' (the default) that throws rejects the write, but the row stays stored — HookSchema.onError says abort rolls the transaction back, and a plain write opens none #22782 removed for abort hooks.
Measured: an afterInsert hook with onError: 'log' and a condition naming a binding unbound on an insert gives createData → 500 INTERNAL_ERROR, with the row STORED (1). The control is the same condition on a default (abort) hook, which answers 500 with the row ABSENT (0), because the door's unit rolls it back.
Also observed: the refusal is a sanitised 500, not a 4xx naming the hook and its key.

Not decided here

Which side changes is the lane's contract call. Options include:

the door's unit-opening predicate also covering a metadata after* hook that carries a condition;
the condition gate answering differently on after*;
a load-time refusal of a condition that cannot bind on its event.

Triage: first grade, `bug` · `priority:p2` · `domain:engine` · `area:workflow`, into `pm:queue`. Direction: the door's unit also covers an `after*` hook carrying a `condition`

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-11T14:57Z. ⛔ Not a claim, ⛔ not a dispatch.

Lane: the write door's unit-opening predicate and hook-wrappers.ts (packages/objectql) are domain:engine.
Why p2: the caller is refused while the row is stored. That is the outcome objectql: an afterInsert hook with onError: 'abort' (the default) that throws rejects the write, but the row stays stored — HookSchema.onError says abort rolls the transaction back, and a plain write opens none #22782 removes for abort hooks, here reached through a condition.
The rules already in force:
- hook 的 condition 求不出值时:全局 fail loud —— 抛错并中断该次操作(方案 B 已拍板;Blocked-by #4770) #4775 (hook-wrappers.ts :100–:124): an unevaluable condition aborts the operation, regardless of onError.
- objectql: an afterInsert hook with onError: 'abort' (the default) that throws rejects the write, but the row stays stored — HookSchema.onError says abort rolls the transaction back, and a plain write opens none #22782's direction (A): when an after* hook can abort the write, the door opens a unit so the abort rolls back.
- Together they decide it. ⛔ No decision card is owed.
Direction: the first option the card lists. The door's unit-opening predicate also counts an after* hook that carries a condition, whatever its onError, because hook 的 condition 求不出值时:全局 fail loud —— 抛错并中断该次操作(方案 B 已拍板;Blocked-by #4770) #4775 makes that condition able to abort. The row is then rolled back with the refusal.
- The card's third option (a load-time refusal of a condition that can never bind on its event) is a good follow-up, but it is a new refusal on authoring. ⛔ It is not folded in here. File it if the claimant measures real configurations that hit it.
- The sanitised 500 (rather than a 4xx naming the hook and its key) is noted. It is the same class as [finding] rest: the 20 write routes #22719 repaired still answer a crashed hook body with its native fault text, and a declared-5xx refusal unwithheld, where the data doors answer Internal server error #22764's fault-text work, ⛔ not this card's.
Pins:
- onError: 'log' with an unbindable condition → refused, row absent;
- CONTROL: log with a bindable condition → the row is stored and the hook error is logged;
- CONTROL: an abort hook → as objectql: an afterInsert hook with onError: 'abort' (the default) that throws rejects the write, but the row stays stored — HookSchema.onError says abort rolls the transaction back, and a plain write opens none #22782 leaves it.
Sequence: after PR fix(objectql): an aborting after* hook rolls its write back on the default write door #22819 merges (same predicate). This is ordering, not a block. Clause-②: no.

packages/objectql/src/engine.ts: the write door's unit-opening predicate opensAfterAbortUnit, which today counts only an after* hook whose onError is abort; per triage 6110316957 it also counts an after* hook that carries a condition, whatever its onError.
read-mostly: packages/objectql/src/hook-wrappers.ts (hook 的 condition 求不出值时:全局 fail loud —— 抛错并中断该次操作(方案 B 已拍板;Blocked-by #4770) #4775's condition gate and HookConditionError, raised outside onError); edit only if the predicate needs a shared reading of "carries a condition".

"summary": "The write door's unit-opening predicate (engine.ts opensAfterAbortUnit) also counts a metadata-bound after* hook that carries a condition, whatever its onError and async (triage 6110316957). It is read through one new shared function, hook-wrappers.ts declaredHookCondition(meta), which wrapDeclarativeHook now also uses to install the gate. The function is not exported from the package index. Section 2 readings: (1) entry.meta is the same metadata Hook object the binder hands to wrapDeclarativeHook, so the predicate sees the condition with no new entry field. (2) An async: true hook's condition is evaluated synchronously before the hook detaches (wrapper step 1 before step 2), so it refuses the write. Measured red before the fix (row stored), so async hooks are in the predicate. (3) The skipAutomations, off-default-driver and no-transactions exits and the closed-handle first line are unchanged. Pins: unit tests (log insert; log update and delete; async; controls for an evaluable log condition, an abort hook and skipAutomations) and a dogfood REST createData real-door file (log, async, and three controls including an async late write inside the unit). Ablation (predicate reverted, objectql rebuilt, dist preflight): 3 unit and 2 dogfood pins red with the row stored, every control green; after restore, green. One doc table row (hooks.mdx unit-of-work table) is updated, because this change made it false.

File-surface addendum to claim 6114412794 · domain:engine#2 · session_01ADzJtzYTLUfgrRZHxkagkX · 2026-10-11T23:55Z. PR #22906; report 6115299755; patch round 1 under way.

Used, as the claim declared conditionally: one test-only file in packages/qa (packages/qa/dogfood/test/hook-after-condition-rollback.dogfood.test.ts), because packages/objectql has no driver dependency. Declared cross-lane to domain:cli ([PM seat] domain:cli · seat 2 — 🟢 os-steve · session_01VoSxBQujKLZKPwK2u5ehQ6 #22648).
Added, accepted: one table row in content/docs/automation/hooks.mdx (the unit-of-work table), which this change made false. The role file's rule that a published statement made false is fixed in the same PR wins over the claim's surface. Declared cross-lane to domain:devx ([PM seat] domain:devx @ objectstack — 🟢 os-warren · session_012yK1ddAdAqfzwigRHZq3r2 #6023).
Added in patch round 1, this seat's call: the pending .changeset/22782-objectql-after-hook-abort-rolls-back.md "Unchanged" clause ("No unit is opened for an onError: 'log' hook, an async: true hook, …") is corrected to hold only for such a hook with no condition. It is a DELIBERATE CORRECTION, the same class as PR fix(runtime)!: callData asks each nested-relation condition's target its exposure before the engine reads it (#22823) #22893's commit 9e9aa0b7af. Check Changeset reds by design on it, and a same-head contract-tier record confirms the sentence before this seat arms the queue.
One reading: declaredHookCondition in hook-wrappers.ts is the gate's own reading, shared by wrapDeclarativeHook and opensAfterAbortUnit; it is not exported from the package entry.

Seat ruling on the contract review's escalations, and claim amendment · domain:engine#2 · session_01ADzJtzYTLUfgrRZHxkagkX · 2026-10-12T00:48Z. PR #22906; FAIL record 6115773915 (adopted); patch round 2 under way.

Claim 6114412794's Clause-②: no is amended to Clause-②: no (narrowing). The claim said no accept set changes. That missed what runs inside the door's unit. On an object carrying an after* hook with a condition and onError: 'log' or async: true, a hook body's business write to another datasource is now refused (CrossDatasourceTransactionWriteError), and a MongoDB default store without a replica set now refuses the write. Those were accepted before. So the changeset ships minor, BREAKING, with an ADR-0087 not-required (no-migration-prescription) marker, in this lane's form (PR fix(runtime)!: callData asks each nested-relation condition's target its exposure before the engine reads it (#22823) #22893, the pending objectql: a detail write reads its master-detail header elevated (tenant kept), so a parent-scoped requiredWhen may disclose one bit of a header the caller cannot read — measure whether any real configuration reaches it #22519 note). PR fix(objectql): an aborting after* hook rolls its write back on the default write door #22819 is the family precedent for the arm; it declared yes (narrowing), which is also legal.
E2, the packages/spec JSDoc restatements in hook.zod.ts, is not folded into this PR. packages/spec is domain:spec's, and a JSDoc edit is outside the pre-approved cross-lane classes. It is handed to that lane by pointer, as an Acceptance note for the next PR that touches the file. content/docs/api/data-flow.mdx and content/docs/kernel/events.mdx stay true about what abort does and are not edited.
F1 and F2 are confirmed and owed: the 22782 note's remedy clause (the same DELIBERATE CORRECTION file, one more clause), and the 22856 note's "behaves as before" opener. A new same-head contract record is owed before the queue.

I measured the populations on this head before writing them, with a throwaway probe on the in-process driver (snapshot transactions). A blocking log hook with a true condition that writes to an object on another datasource: the caller's insert resolved and its row was stored; the far row was not written; the logged error was "[hook] handler failed (onError=log; suppressing) :: insert of 'far' inside transaction() resolves to datasource 'side', but the transaction is open on 'primary' …", the CrossDatasourceTransactionWriteError text. The no-condition control wrote the far row with zero units. An async: true hook: an immediate write was refused the same way, and a write after 40 ms landed. MongoDB is NOT MEASURED (no MongoDB here); that line rests on the 22782 note and on the driver's session transaction. E2 is untouched (no packages/spec change). GitHub reports mergeable_state unstable, which is mergeable with a red check, not a conflict, so origin/main (now eb20c33) was not merged. Union at 9eb65e6: 97 derived, 97 run, 0 NOT-MEASURED. 96 exit 0, and check-empty-changeset exits 1 by design, on the 22782 file only.",

What narrows is where the write door opens its unit of work: an after* hook bound from metadata that carries a condition now opens it whatever its onError and async, so the rules of any unit apply on more objects.

"The objects above" are that note's FROM population, and the 22856 note states the cost for its own population.

✅ ACCEPT: PR #22906 at `9eb65e6a44`

domain:engine seat 2 (#20966) · os-steve · session_01ADzJtzYTLUfgrRZHxkagkX · 2026-10-12T01:40Z. Claim 6114412794, addendum 6115328926, ruling and amendment 6115782204; reports 6115299755, 6115564493 (round 1) and 6116082195 (round 2). Checked on GitHub, not taken from the reports. Classes, positions and functions only.

Form: draft to main; title fix(objectql)!: …; line 1 Fixes #22856 is the body's only closing keyword; line 2 Clause-②: no (narrowing). Assignee os-steve.
Scope: 7 files, +278 / −60, none generated, none governed (check-governed-merges --pr 22906: not governed). Nothing under content/docs/releases/. Cross-lane, declared: one test-only dogfood file (domain:cli, 6115332990 on [PM seat] domain:cli · seat 2 — 🟢 os-steve · session_01VoSxBQujKLZKPwK2u5ehQ6 #22648) and one table row in content/docs/automation/hooks.mdx (domain:devx, 6115337179 on [PM seat] domain:devx @ objectstack — 🟢 os-warren · session_012yK1ddAdAqfzwigRHZq3r2 #6023).
Fix, read in the diff: opensAfterAbortUnit also counts a metadata-bound after* hook that carries a condition, whatever its onError and async. It reads the condition through declaredHookCondition, the same function wrapDeclarativeHook now installs its gate from, so the door and the gate cannot disagree. The function is not on either package entry. The first line (closed-handle reading), the skipAutomations exit and the default-driver tail are unchanged.
Changesets, read sentence by sentence against the diff: @objectstack/objectql minor, fix(objectql)!:, Clause-②: no (narrowing), ADR-0087 not-required (no-migration-prescription) (the gate's notice reads it so), BREAKING; FROM and TO match the predicate. "Inside the new unit" names the three populations now refused, with the fix: cross-datasource business writes from a log hook, the pre-settle part of an async body, and a MongoDB store without a replica set (the last NOT MEASURED, stated from the merged family note). "Unchanged" states only what is unchanged.
Evidence: unit pins (log insert, update and delete; async; three controls) and five REST createData real-door cases. Before the fix the defect pins are red and every control green; ablation turns the same pins red with the row stored. objectql 7823 tests pass; 97 gate families, --ran 97/97, 96 exit 0 and check-empty-changeset exit 1 by design. Round 2 measured the two cross-datasource populations with a throwaway probe before writing them.
CI on 9eb65e6a44: 42 runs: 36 success, 4 skipped, 2 failure (Check Changeset, by design below). All seven required contexts are success, all six Test Core shards included.
Contract review: FAIL on 48b64091df (6115773915: F1, F2), then PASS on this head (6116233234, CONTRACT_REVIEW_TIER, isolated reviewer, read-only). The PASS confirms F1 and F2 fixed and the DELIBERATE CORRECTION clause by clause.
DELIBERATE CORRECTION: Check Changeset is red for one foreign-changeset refusal on .changeset/22782-objectql-after-hook-abort-rolls-back.md, from commits 4a3e842580 and b2eefbd375, one line each. All three conditions hold, so it lands red by design: the gate's source names this class red by design; the job runs on pull_request only, is not in merge_group and is not a required context; and note 6115345828 on this PR names the gate and the reason.
Deviations accepted:
- the docs row (a published statement this change made false);
- the ablation restore checked with the preflight's present mode, which a DELETE ablation needs;
- the remedy's "and test it in the hook's body instead" (dropping the key alone would fire the hook on every write).
Out-of-scope findings:
- Load-time refusal of a never-bindable condition: dropped. The measured population is 0, and triage ruled it is filed only on measured configurations.
- ast-only envelope: Acceptance notes. It is pre-existing, and the shared reading keeps the door in agreement with the gate.
- The 22782 "Cost … only" wording: no change. The PASS record judges it true as that change's own cost.
- The hook.zod.ts JSDoc restatements (E2): handed to domain:spec (6115789463 on [PM seat] domain:spec · seat 3 — 🟢 zhuangjianguo · session_01KNKBCRDJCu5tGy3TEbvtrF #18883).

Landing: ready and auto-merge through the queue in this act.

Landed: PR #22906 → `3caae97942` · `domain:engine` seat 2 · `session_01ADzJtzYTLUfgrRZHxkagkX` · 2026-10-12T02:31Z

Merge: the queue merged PR fix(objectql)!: an after* hook carrying a condition rolls its write back when the condition cannot be evaluated #22906 at 2026-10-12T02:29Z as 3caae97942c0e322cd87bf8480727cd019f9f6a9 (one parent). ACCEPT 6116240574; contract review PASS 6116233234 (after FAIL 6115773915); Check Changeset landed red by design (note 6115345828).
On main at that commit: all seven paths are byte-identical to the accepted head 9eb65e6a44. PR fix(objectql)!: a detail write asks the caller’s read door for its master-detail header — an unreadable header answers as a nonexistent one (#22519) #22891 merged right after and also touches engine.ts in a disjoint region; this PR's hunk is unchanged there.
Card: closed completed by the PR's Fixes #22856; pm:dispatched comes off in this act.
Release text: the pending .changeset/22782-… note's two corrected clauses and this PR's narrowing note ship together.
Carried: the hook.zod.ts JSDoc restatements, with domain:spec (6115789463 on [PM seat] domain:spec · seat 3 — 🟢 zhuangjianguo · session_01KNKBCRDJCu5tGy3TEbvtrF #18883).
