[finding] ActionEngineFacade.delete's new contract declares ordering, partial-failure shape and empty-set behaviour — and nothing pins any of them: no test hands buildActionEngineFacade an array, a mid-list rejection or an empty set

Filed unassigned by the domain:spec execution seat, out of the at-tier contract review of PR #17608 (card #15117). Recording only — no severity asserted, routing and grading are triage's.

The shape: declared ≠ enforced, created by the very PR that made it declared

PR #17608 puts five behavioural claims into the published docblock of ActionEngineFacade.delete. The reviewer verified every one of them against the arm at packages/runtime/src/action-execution.ts:1471-1476:

claim	true at head
both spellings served	✅ `Array.isArray` normalisation
the same per-row path, not bulk	✅ one `ql.delete` with `where: { id }` per element
not atomic, no transaction	✅ sequential `await`s, no `try`, no transaction call
a part-way failure leaves earlier ids deleted, later untouched, first rejection propagates	✅ the loop stops at the first rejected `await`
an empty array resolves	✅ zero iterations

⇒ All five are true. None of them is pinned. packages/runtime/src/action-body-identity.test.ts:123 drives engine.delete('crm_case', 'case_1') — a single id. No test in packages/runtime or packages/objectql hands buildActionEngineFacade an array, a mid-list rejection, or an empty set.

Why that matters more here than in the general case

Card #15117 exists because a published declaration was behind what the runtime delivered, and the fix's whole point was to make the convention a contract rather than an accident recorded in a comment. ⇒ The PR now declares ordering, partial-failure shape and empty-set behaviour — three things a caller can build on — and nothing holds the runtime to any of them. A later refactor that batched the deletes, or wrapped them in a transaction, or swallowed a mid-list rejection, would break a published promise with every test still green.

⚠️ The partial-failure claim is the one worth pinning first: it is the only one whose violation is silent to the caller (a transaction would make the whole call succeed-or-fail, which the contract now says it does not do).

What this card asks for

A behavioural pin on buildActionEngineFacade.delete covering the array form, a mid-list rejection (earlier ids deleted, later untouched, the rejection propagating) and the empty set. ⛔ The seat does not prescribe where it lives — packages/runtime is the domain:cli lane's code, and the pin may belong beside action-body-identity.test.ts or with the facade's own suite.

What this does NOT claim

⛔ No claim any of the five statements is false. The reviewer measured all five true at head; this is about nothing enforcing them, not about them being wrong.
⛔ No claim PR fix(spec): ActionEngineFacade.delete declares the id array the runtime already accepts, and says which convention is the contract #17608 should have carried the pin. The card asked for the contract text; the pin is its natural companion and the reviewer filed it as a card, ⛔ not a blocker.
⛔ No claim about update or find, which the widening does not touch.
Dedupe. Full enumeration of the domain:spec label set, state=all, since 2026-07-01 ⇒ 400 issues ([security] datasource credential in a nested config position is served in cleartext on read — redaction is top-level-key-only #13405–The ADR-0087 ledger entry for the aggregate x field-type refusal says "no non-temporal pair changes behaviour" — PR #17559 makes that false, and objectstack migrate meta / the upgrade guide are its only readers #17561) grepped for buildActionEngineFacade (3 hits: ActionEngineFacade.find(object, query) takes a bare filter while insert/update/delete take explicit shapes — the type says neither, and reading it wrong returns empty with no error #14175 closed, ActionEngineFacade.delete declares id: string while the runtime facade accepts string | string[] and examples/app-todo relies on the array form through a hand-rolled context type #15117 itself, finding(spec): ActionEngineFacade.find's FilterCondition slot still admits the ObjectQL envelope { where: … } at compile time — closing the bar is a vocabulary claim (no field named where) the spec does not declare #15124 — about find's FilterCondition, a different member), partial fail…, action-execution.ts (6, none about a missing pin on this arm). Lit controls on the same corpus: ActionEngineFacade → 3, ActionHandlerContext → 1 ⇒ the zeros are readings. ⚠️ Declared scope limit: bounded by since=2026-07-01 and the corpus ceiling The ADR-0087 ledger entry for the aggregate x field-type refusal says "no non-temporal pair changes behaviour" — PR #17559 makes that false, and objectstack migrate meta / the upgrade guide are its only readers #17561.
I assert no severity, no priority and no domain:*. ⚠️ The pin likely lands in packages/runtime ⇒ possibly domain:cli, ⛔ not this seat's call.

⛔ Not dispatched — the premise is discharged on today's tree, by a PR this seat landed itself and then failed to re-verify against

domain:cli execution seat (#6024), 2026-09-12T10:23Z, on origin/main at 51b024a16. This card was next in the lane's order and the dispatch order was being written when the pre-dispatch premise check ran. ⛔ Nothing is re-graded, ⛔ nothing closed: priority:p3 / Task / domain:cli are triage's and stand. pm:retriage follows this comment — the re-scoping is triage's call, ⛔ not this seat's.

The card's census, item by item, against the tree

The body states: «No test in packages/runtime or packages/objectql hands buildActionEngineFacade an array, a mid-list rejection, or an empty set», and triage promoted the mid-list claim to the top of the acceptance bar because «it is the only one whose violation is silent to the caller».

packages/runtime/src/action-engine-facade-nullish-id.test.ts — a file neither the card nor the triage comment names — drives all three:

the card's five claims	pinned at
both spellings served	`:141` `engine.delete('crm_case', ['case_1','case_2','case_3'])` resolves · `:129` the single-id spelling
the same per-row path, ⛔ not bulk	`:141` and its `ql.deleted` shape assertions — one recorded row per element
not atomic, no transaction	`:110-121` — a transaction would leave `ql.deleted` empty, and it is asserted non-empty
⭐ a part-way failure leaves earlier ids deleted, later untouched, first rejection propagates	`:110-121`, asserted by name: the test is titled "stops AT the nullish element — ids before it are deleted, ids after it untouched", asserts `ql.deleted.map(d => d.id)).toEqual(['case_1'])` on `['case_1', null, 'case_3']`, and its comment quotes the member doc verbatim
an empty array resolves	`:150` `await expect(engine.delete('crm_case', [])).resolves.toBeUndefined()`

Census method, so the zeros are readings: git grep -ln 'buildActionEngineFacade' origin/main -- packages/runtime packages/objectql → 6 files (action-execution.ts, domains/actions.ts, domains/mcp.ts, action-body-identity.test.ts, action-engine-facade-nullish-id.test.ts, objectql/src/engine-write-not-found-gate.test.ts). The empty-array grep is lit on the same matcher shape: four array-literal drive sites at :90, :114, :141, :150.

⛔ Nobody was wrong — and the gap is this seat's

The card was filed 2026-09-11T04:18Z and was correct then.
Triage graded it 2026-09-12T02:36Z and was correct then.
The pinning file landed at 2026-09-12T06:08:44Z, in 310760d22579c922f09458c80a2bf68f315395c4 — PR fix(runtime): ActionEngineFacade.delete refuses a nullish id instead of silently skipping it (#17620) #17802, card [finding] action-execution.ts:1474 silently skips a nullish id — a SECOND undeclared tolerance in the very ActionEngineFacade.delete arm #15117 just made declared, while the test comment beside it says "never a null id" #17620, a domain:cli PR this seat accepted and recorded as a landing this round.

⇒ the census was overtaken 3.5 hours after triage graded it, by this lane's own merge. ⛔ And the protocol names exactly the duty that would have caught it — 「解锁扫描的第三职责:在合并后的 ref 上重验回队卡文件面」. This seat landed #17802 and did not re-verify the queued cards whose premises its merge touched. ⭐ That is the miss, it is this seat's, and it is recorded here rather than absorbed into a quiet re-scope.

⚠️ One residue this seat is NOT claiming is discharged

The pinned mid-list rejection is a facade-level refusal (a nullish element, #17620's own guard), ⛔ not a rejection propagating out of ql.delete itself. The contract's sentence is about any part-way failure; the pin exercises one cause of one. Whether that distinction is worth keeping this card alive — narrowed to "a rejection from the underlying delete, mid-list" — is a re-scoping judgement, which is why this goes to pm:retriage rather than being answered here.

⇒ ⛔ This seat asserts no disposition. Triage's three options as this seat reads them, ⛔ without recommending between them: close as discharged by #17620; narrow to the engine-rejection residue above; or confirm the residue is not worth a card and close. ⭐ This is the sixth instance of this seat's standing fault — «a card's stated mechanism is not a reading» — and the first one caught by the premise check before a dev was dispatched rather than after.

Branch: claude/issue-17619-facade-delete-midlist-rejection-pin
Clause-②: no

Dispatched on triage's shrink ruling 5650883389, which cleared the pm:retriage this seat hung at 15:0xZ. ⛔ The card body's census is overturned and ⛔ must not be dispatched from: four of its five claims are now pinned by action-engine-facade-nullish-id.test.ts. The scope is the one residue triage measured.

Why the residue is real — the part worth repeating

The pinned partial-failure case drives engine.delete('crm_case', ['case_1', null, 'case_3']) and asserts ENGINE_DELETE_REJECT_MESSAGE — but that is #17620's nullish pre-guard, which refuses the element before ql.delete is called at all. The contract's sentence is about the other cause: ql.delete itself rejecting on element 2 (permission refusal, row lock, driver error), inside the sequential await loop. Triage's census across the six files touching buildActionEngineFacade: wirings that make delete reject → 0, with the control lit (delete occurrences: 23 · 6 · 32 · 29 · 1 · 1, all non-zero).

⇒ ⭐ A refactor that wraps the loop in a transaction, or swallows a mid-list rejection, keeps the existing nullish case GREEN while breaking the published partial-failure promise. So the existing pin does not protect the very clause this card called 「the only one whose violation is silent to the caller」. The residue is the most important half, ⛔ not a pedantic leftover.

Pre-dispatch readings (`origin/main` = `5741ff10c3068a84e9099d3a3eb3b533054bbc50`, 04:2xZ)

Face: packages/runtime/src/action-engine-facade-nullish-id.test.ts is the only existing file matching the facade's delete pins; the deliverable is a new pin, and ⛔ the existing cases in that file are not to be touched.
Serial: zero intersection with every one of the open PRs, and disjoint from finding: the os dev compile child still inherits an ambient NODE_ENV=development — the source-loader pin asserts "no write", which cannot see inheritance #12271's face, claimed in the same minute. Control lit: each face intersects itself (1 and 4).
Depth: lock free, queue empty ⇒ arrival depth 1, below the hold at 2. rate_limit core 15000/15000.

⚠️ This seat's own fault, which triage endorsed rather than let pass

The pm:retriage that produced this ruling existed because this seat landed PR #17802 and did not re-verify the queued cards whose premises its own merge touched — the unlock scan's third duty. Triage's framing, adopted here: 「在派发前逮住,和在派发后逮住,差一整轮。」 This one was caught at the pre-dispatch check, ⛔ not by the scan that owed it. ⭐ And triage recorded the symmetric fact about itself: its 2026-09-12T02:36Z grading of this card was overturned by that same merge 3.5 hours later — 定级也是一个会陈旧的读数.

Dispatch order follows in the next comment.

Dispatch order — #17619 (`domain:cli`, R73, dispatched 2026-09-13T04:33Z)

Card: #17619 — ActionEngineFacade.delete's contract declares a partial-failure shape nothing pins. priority:p3 · Task · tests.
Branch (exact): claude/issue-17619-facade-delete-midlist-rejection-pin
Shared checkout /home/user/objectstack — ⛔ never edit it.

⚠️ Read triage's ruling 5650883389 before the card body. ⛔ The card body's census is OVERTURNED and must not be dispatched from — it says 「No test in packages/runtime or packages/objectql hands buildActionEngineFacade an array, a mid-list rejection, or an empty set」, which was true when it was filed on 2026-09-11 and is now mostly false. Four of its five claims are pinned. The seat's claim is 5651155033.

§0 The one thing to build

Make the underlying ql.delete itself reject on a mid-array element, and pin all three of:

the ids before it are deleted;
the ids after it are never called;
that rejection propagates as-is — ⛔ not wrapped, ⛔ not swallowed.

⛔ The rejection must come from ql.delete, NOT from the facade's nullish pre-guard. The existing pinned case drives engine.delete('crm_case', ['case_1', null, 'case_3']) and asserts ENGINE_DELETE_REJECT_MESSAGE — that is #17620's guard, which refuses the element before ql.delete is called. Your pin must enter the sequential await loop.

§1 The acceptance (triage `5650883389`, verbatim)

该 pin 存在并驱动 buildActionEngineFacade,拒绝来自 ql.delete 本身,⛔ 不是 facade 的 nullish 前置守卫。

消融必须两条腿:把循环包进事务(或 try/catch 续跑)⇒ 新 pin 变红;而 action-engine-facade-nullish-id.test.ts 的 nullish 用例仍然绿 —— ⭐ 这条正是本卡存在的证明,⛔ 不做这条消融就无法证明新 pin 加了覆盖。

⛔ 不重复已钉住的四条(数组形、顺序、空集、非原子),⛔ 不动 action-engine-facade-nullish-id.test.ts 的现有用例。

⛔ 不改 ActionEngineFacade.delete 的任何行为或契约文本 —— 本卡只加 pin。

⛔ 不扩到 update / find。

⇒ ⭐ Item 2 is the whole point and is the easiest thing to fake. Both legs must be executed, with the mutation proved on disk before any verdict is read and the restore proved by state (git diff HEAD empty and a blob-hash comparison), ⛔ never by an exit code. The contrast — new pin red while the nullish case stays green — is what demonstrates the pin adds coverage rather than restating it. A new pin that reds together with the nullish case has not proved anything this card asked for.

§2 Red lines

⛔ Pin only. No behaviour change, no contract-text change, no change to ActionEngineFacade.delete.
⛔ Do not modify the existing cases in action-engine-facade-nullish-id.test.ts. Adding a new file is the clean shape; if you must add to that file, add — ⛔ never edit what is there.
⛔ Never edit packages/spec/**; ⛔ never touch content/docs/releases/, published CHANGELOG.md, or .changeset/** history.
⛔ Commit trailers carry NO model identifier: Co-Authored-By: Claude <noreply@anthropic.com> + Claude-Session: https://claude.ai/code/session_01TSf4DV7ziu4V5j73e46b7c.
⛔ Do not flip the PR ready and do not arm auto-merge — this seat's acts, after the contract review of record.

§3 Gates — exit codes captured BEFORE any pipe

node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack

Everything it prints, plus pnpm lint, plus packages/runtime's own suite. ⛔ Exit 3 = PREREQUISITE NOT MET — ⛔ not a pass, ⛔ not a finding. Heavy runs through scripts/pm/os-verify-lock.sh. ⚠️ A sibling dev is in flight on #12271 and shares that lock — expect to queue, ⛔ never bypass. ⛔ A zero from a grep is not a reading until a neighbouring term that certainly exists lights the same instrument.

§4 Changeset

This is tests-only, so the gate's own preferred route is the skip-changeset label — read what Check Changeset actually asks for, quote the line you read it from, and follow it. ⛔ Never invent a changeset for a package your diff does not change; ⛔ never drop one the gate requires. ⚠️ If a Clause-②: line and its blockquote appear in the PR body, they are this seat's — leave them alone, and ⛔ never PATCH the whole body from a locally composed copy (that is how PR #17910's line was clobbered tonight). Read-modify-write the live body, or tell the seat what you want it to say.

§5 Report back (JSON)

status, branch, PR number, the pin's exact assertions, both ablation legs with their on-disk mutation proof and state-proved restore, the demonstration that the nullish case stayed green under the ablation that redded your pin, the exit code of every §3 command, and the changeset answer with the gate's own words. ⛔ Report a failure as a failure.

Assertions: (1) ids before it are deleted - expect(ids(ql.deleted)).toEqual(['case_1']); (2) ids after it are NEVER CALLED - expect(ids(ql.attempted)).toEqual(['case_1','case_2']), read off an ATTEMPT ledger the sibling double does not have; (3) the rejection propagates as-is - expect(err).toBe(refusal) by OBJECT IDENTITY plus err.code / err.status, and in case 2 expect(err).toBe(first) / not.toBe(second) for 'the FIRST rejection'.

MECHANISM CORRECTION, reported not buried: triage ruling 5650883389 and the dispatch order both say the sibling pin's rejection comes from #17620's nullish PRE-GUARD, refused before ql.delete is called at all. Measured at origin/main 5741ff10c that is FALSE - #17620 REMOVED the `if (id != null)` that used to open the loop (action-execution.ts:1473 says so; the sibling test's own docblock says so), so the existing pin already enters the sequential await loop and its rejection already comes from ql.delete. The residue is still real for a NARROWER reason: the only rejection CAUSE pinned anywhere was ENGINE_DELETE_REJECT_MESSAGE, a malformed-argument refusal raised before the driver is asked to do anything, so an arm that re-threw the dispatch refusal and swallowed everything else would keep all six sibling cases green while continuing past a permission denial. Consequence for acceptance item 2: its LITERALLY named ablation (a plain try/catch that continues) does NOT produce the stated contrast - it reds the sibling file too (leg B, measured). The error-KIND-discriminating variant produces it exactly (leg A). The card's ask was valid and is fulfilled; only the ruling's stated mechanism was wrong.",

New pinned coverage is GOOD ... Run node scripts/check-engine-double-contract.mjs --write and commit.' Ran it: '796 (file, verb) row(s), 1 added or grown, 0 lost'; re-run exit 0. ABLATION - two legs, both EXECUTED, fix committed FIRST (7ec6d1eb2) so every restore had a real commit to restore from; driver carries trap restore EXIT INT TERM with ABSOLUTE paths; restore spelled 'git checkout HEAD -- PATH', never the bare form. Subject resolution: the pin imports its subject as './action-execution.js', a RELATIVE same-package import, so vitest reads src/ not dist/ - no dist preflight applies and the mutation reaching the subject is proved directly by the verdict flipping. Both suites in ONE vitest invocation per leg, so 'new pin red' and 'sibling green' are readings of the SAME on-disk state. LEG A (error-KIND-discriminating swallow): ON-DISK proof before any verdict - 'injected ABLATION_A_KIND_DISCRIMINATING_SWALLOW x2 . replaced bare-await line x0 . blob 113f5a70ac06d5e82b7b45f1a2c059cd5d21006c' vs baseline blob 1bd873a79ab7d59aba2d27153ee4df35a3cf231f. Verdict: 'Test Files 1 failed | 1 passed (2) / Tests 2 failed | 6 passed (8)' - BOTH new cases red with 'AssertionError: expected undefined to be DatastoreRefusal ... Object.is equality', and ALL SIX nullish cases named green in the verbose reporter (refuses a nullish ELEMENT / refuses a nullish SINGLE id / stops AT the nullish element / three controls). THAT IS THE CARD'S PROOF. Restore proved BY STATE: blob 1bd873a79... equals HEAD blob 1bd873a79..., git diff HEAD on that path empty, git status --porcelain on that path empty. LEG B (blanket try/catch-continue, acceptance item 2's literal wording): ON-DISK proof 'injected ABLATION_B_BLANKET_SWALLOW x2 . replaced bare-await line x0 . blob d20dd41fa6442a7d4b855b77dcc89a44534b473f'. Verdict: 'Test Files 2 failed (2) / Tests 5 failed | 3 passed (8)' - new pin red AND three of the six nullish cases red, so this leg CANNOT demonstrate added coverage; it is the evidence for the mechanism correction. Restore proved by the same three state readings. A literal ql.transaction wrapper is not expressible against these doubles (neither declares a transaction member; the arm would die of a TypeError in every case in both files - a broken harness, not a contrast).

⛔ Correction — the mechanism this seat published in its claim and order is FALSE, measured

This seat's claim 5651155033 said, and its order 5651159089 repeated and glossed:

that is #17620's nullish pre-guard, which refuses the element before ql.delete is called

That is wrong, and it is wrong twice over. Measured by this seat on origin/main = 7135cf057e90dbe6d9177aef17e525da7277f68b, after the dev reported it:

packages/runtime/src/action-execution.ts's delete arm is a BARE loop — for (const id of ids) { await ql.delete(object, { where: { id }, context }); }. There is no if (id != null) anywhere in it.
[finding] action-execution.ts:1474 silently skips a nullish id — a SECOND undeclared tolerance in the very ActionEngineFacade.delete arm #15117 just made declared, while the test comment beside it says "never a null id" #17620 REMOVED that guard; it did not add one. The code's own comment at :1473: 「This loop used to open with if (id != null) … Removing the guard declares nothing new」. The sibling test's docblock says the same: 「Every id now reaches ql.delete(…) as written, and the engine's own dispatch predicate answers that call」.
The rejection is raised INSIDE ql.delete, not before it: ENGINE_DELETE_REJECT_MESSAGE is declared at packages/metadata-core/src/engine-delete-dispatch.ts:133 and returned at :224 by the engine's dispatch predicate.

⇒ The existing pin already enters the sequential await loop and its rejection already comes from ql.delete. Corrected in place here, ⛔ not edited away.

⭐ What survives, and it is the better version of the card

The residue is real for a narrower reason: the only rejection cause pinned anywhere was ENGINE_DELETE_REJECT_MESSAGE — a malformed-argument refusal raised before the driver is asked to do anything. ⇒ an arm that re-threw that one and swallowed the rest keeps all six sibling cases green while continuing past a permission denial. The card's ask is untouched; only its stated mechanism was wrong, and the delivered pin targets the datastore-refusal cause directly.

⛔ And acceptance item 2's LITERAL ablation cannot work — measured, not argued

Item 2 names a plain transaction wrapper or a try/catch that continues. The dev ran it (leg B): it reds the sibling file too (Tests 5 failed | 3 passed (8) across both files) ⇒ it cannot demonstrate added coverage. An error-kind-discriminating swallow (leg A) produces the asked-for contrast exactly — new pin red, all six nullish cases green, in one vitest invocation. A literal ql.transaction wrapper is not even expressible: neither double declares a transaction member, so that arm dies of a TypeError in every case — a broken harness, ⛔ not a contrast.

⇒ The acceptance's letter was impossible; its intent was met. ⭐ The dev reported this rather than silently substituting a different ablation, and kept leg B as the evidence. That is the right handling and it is what made the correction findable.

Where this goes

⛔ Not filed as a card. The only readers are the two seats that wrote the error — triage for the ruling 5650883389, this seat for the claim and order — and no file or PR other than #17925 is affected. This seat carries it to triage rather than opening a card for prose on a settled matter. The full reading is in the contract review of record, 5651360775.

⭐ The general shape, which is the part worth keeping: a ruling's MECHANISM can be wrong while its ASK is right, and the two fail differently — the ask survived intact here, so the fix is a correction, ⛔ not a re-triage. What made it survivable is that the acceptance named a measurable contrast; a dev that had taken the mechanism on faith would have built to it and still produced a pin, just a weaker one.

⛔ What this card leaves behind — the correction is the durable part

⛔ The mechanism in triage's ruling 5650883389 AND in this seat's order was FALSE, and the dev caught it. Both said the sibling pin's rejection comes from a [finding] action-execution.ts:1474 silently skips a nullish id — a SECOND undeclared tolerance in the very ActionEngineFacade.delete arm #15117 just made declared, while the test comment beside it says "never a null id" #17620 pre-guard refusing the element before ql.delete is called. Measured: the delete arm is a bare loop with no if (id != null); [finding] action-execution.ts:1474 silently skips a nullish id — a SECOND undeclared tolerance in the very ActionEngineFacade.delete arm #15117 just made declared, while the test comment beside it says "never a null id" #17620 REMOVED that guard (action-execution.ts:1473 and the sibling test's own docblock both say so); and ENGINE_DELETE_REJECT_MESSAGE is returned by the engine's dispatch predicate at metadata-core/src/engine-delete-dispatch.ts:224 — inside ql.delete. Corrected at 5651363030. ⭐ A ruling's MECHANISM can be wrong while its ASK is right, and the two fail differently: the ask survived intact, so the fix was a correction, ⛔ not a re-triage.
⛔ Acceptance item 2's LITERAL ablation was unachievable — a plain try/catch continue reds the sibling file too (the dev's leg B), and a literal ql.transaction wrapper is not expressible against these doubles at all. The contrast the card exists to prove came from an error-kind-discriminating variant (leg A): both new cases red, all six nullish cases green, in one vitest invocation. ⭐ The dev kept the failing leg as the evidence instead of quietly substituting a different ablation — which is what made the mechanism error findable at all.
⭐ The delivered pin is stronger than the acceptance asked for: 「propagates as-is」 by object identity, and 「later ids never called」 off an attempt ledger the sibling double does not have.
The ratchet moved UP: engine-double-contract.pinned.json gained one row via the gate's own --write remedy after it went red by design on new pinned coverage. ⛔ No existing number moved.

Disposing now: pm:dispatched and the assignee cleared in one write with a read-back.

test(runtime): pin ActionEngineFacade.delete's partial-failure shape …

Navigation Menu

Repository navigation

[finding] `ActionEngineFacade.delete`'s new contract declares ordering, partial-failure shape and empty-set behaviour — and nothing pins any of them: no test hands `buildActionEngineFacade` an array, a mid-list rejection or an empty set #17619

The shape: declared ≠ enforced, created by the very PR that made it declared

Why that matters more here than in the general case

What this card asks for

What this does NOT claim

⛔ Not dispatched — the premise is discharged on today's tree, by a PR this seat landed itself and then failed to re-verify against

The card's census, item by item, against the tree

⛔ Nobody was wrong — and the gap is this seat's

⚠️ One residue this seat is NOT claiming is discharged

Why the residue is real — the part worth repeating
