Description
Found while implementing #10171 (the afterUpdate detach leg). Filed rather than fixed: #10171 is the UPDATE verb, this is the DELETE verb, and the blast radius differs enough to deserve its own review.
What is broken
installAttachmentLifecycleHooks (packages/services/service-storage/src/attachment-lifecycle.ts) hands file ids from beforeDelete to afterDelete on the hook context:
const STASH_KEY = '__attachmentFileIds';
// beforeDelete: ctx[STASH_KEY] = [...fileIds];
// afterDelete: const fileIds = Array.isArray(ctx?.[STASH_KEY]) ? ctx[STASH_KEY] : [];Its comment states the premise: "the engine passes the SAME HookContext object to both events". That was true of the pre-#5574 batch dispatch. Since #5574 (ADR-0058 Addendum II, D1/D2) a predicate write dispatches one context per matched row, and those row contexts are fresh objects spread from the batch context in each phase independently — dispatchPerRowBeforeHooks and buildPerRowAfterContexts in packages/objectql/src/engine.ts. dispatchPerRowBeforeHooks even says so outright:
a per-row context is a fresh object, so a stash written on the context itself dies with the row that held it
So on a predicate delete the stash never reaches afterDelete, fileIds is [], and no tombstone is ever written. The orphaned sys_file stays at status='committed' with deleted_at NULL — and sys_file's declared lifecycle nominates a sweep candidate only via ttl { field: 'deleted_at' } or retention { onlyWhen: { status: 'pending' } }, so it matches neither, the reap guard is never asked about it, and the bytes are stranded permanently. Same terminal state as #10171, reached through the delete verb.
Measured, on the wired engine
Driving real ObjectQL with the lifecycle hooks installed, one join row as the file's last reference:
| case | result |
|---|---|
delete(where: { id: 'a1' }) — by-id |
f1 → status: "deleted", deleted_at set ✅ |
delete({ multi: true, where: { parent_id: 'r1' } }) — predicate |
f1 → status: "committed" ❌ no tombstone |
And directly on the seam, with a probe stash set in beforeUpdate and read in afterUpdate (same context mechanics as the delete pair):
stash seen (dispatch.mode === 'record'): SET
stash seen (dispatch.mode === 'per-row'): LOST
Suggested shape
Drop STASH_KEY and read the departed id from ctx.previous.file_id, which is what #10171's afterUpdate leg already does in this same file. The engine binds previous to the row's pre-image on both phases and both dispatch paths (by-id unconditionally since #7867; per-row from the batch's memoized prior-row read), so one read covers both — and it costs no extra round trip, since the demand is asked per object and attachment-access-hooks.ts already registers a beforeUpdate/beforeDelete here.
Doing so also collapses the two mechanisms this file would otherwise carry for one question ("what file did this join row point at before?"), which is the drift #10171 was filed against.
Worth checking in the same pass: beforeDelete's else if (ctx?.input?.options?.where) limb with MULTI_DELETE_RESOLVE_LIMIT. It exists to resolve a batch-shaped delete, but per-row dispatch always binds input.id, so it looks unreachable on today's engine — the same "a producer that never existed" shape #5906 removed from afterInsert in this file. Confirm before deleting.
Backlinks: #10171 (where found; the update verb's twin of this leak), #9719 (the other #5574 per-row-dispatch bypass on this same object), #2755 (where the tombstone flow landed), #5574 / #5846 (the dispatch change and the previous binding it enabled).

Reopened by the triage seat — this card is not fixed. Provenance: #10392's measured evidence. PR #10241's body sentence "Filed, not fixed: #10240 — the same leak through the delete verb" was written to record that this card was deliberately left open; GitHub's closing-keyword parser ignores the negation and closed it as
completedtwo seconds after the merge (15:10:08Z). PR #10241 fixes the update-verb re-point tombstone; the predicate-delete no-op measured in this card's table (multi: truedelete leavessys_fileatstatus='committed', bytes stranded permanently, no lifecycle sweep matches) is untouched. A closed-completed card asserting an unfixed data-loss defect is the state machine lying — reopening restores the record.Triage on reopen (the card was closed before first touch):
pm:queue,domain:services(lands inpackages/services/service-storage/src/attachment-lifecycle.ts), type Bug. The suggested shape is already precise and mirrors the landed #10171 leg: dropSTASH_KEY, readctx.previous.file_id(bound on both phases and both dispatch paths since #7867/#5846). Include the card's own side-check before deleting theMULTI_DELETE_RESOLVE_LIMITlimb — confirm unreachability, don't assume it.Size/model suggestion: S–M,

Repair is the prescribed shape and mirrors the landed #10171 leg: STASH_KEY dropped, the departed id read from ctx.previous.file_id, which the engine binds on both phases and both dispatch paths (by-id unconditionally since #7867, per-row from the batch doomed-row read). The beforeDelete registration had no work left and is removed, and with it the MULTI_DELETE_RESOLVE_LIMIT limb -- unreachability MEASURED with a positive control, not assumed (table below). Clause-2 measured NO, matching your first reading: no accept/reject set moves and no public surface widens. The only exported symbols are unchanged; STASH_KEY, asIdList and MULTI_DELETE_RESOLVE_LIMIT were all module-private. One observable change beyond the tombstone itself, called out because it is a wiring fact a reviewer will see: sys_attachment now carries ONE beforeDelete registration (the access guard's) instead of two, which moved a pin in storage-service-plugin.test.ts. Already-stranded bytes are NOT swept by this change -- filed separately, see out_of_scope_findings.

(1) PREMISE, measured before any edit, wired ObjectQL, one run: 'A DELETE by-id (dispatch record): f1 -> status=\"deleted\" deleted_at=SET / B DELETE predicate (dispatch per-row): f1 -> status=\"committed\" deleted_at=NULL / C UPDATE by-id: f_old -> status=\"deleted\" deleted_at=SET / D UPDATE predicate: f_old -> status=\"deleted\" deleted_at=SET'. (2) SUITE after fix: '@objectstack/service-storage' -> 'Test Files 24 passed (24) / Tests 405 passed (405)', exit 0. Package build (the real type gate here -- this package has NO typecheck script, so a --filter typecheck would have matched zero scripts and exited 0 having run nothing): 'DTS Build success in 6009ms', BUILD_EXIT=0. (3) ABLATION, predicted signature written to file BEFORE mutating: mutate afterDelete to lose the id on dispatch.mode === 'per-row' (a faithful minimal model of the stash loss). Predicted RED on the predicate pins only. Observed exactly that: 4 failed / 56 passed, the four being the predicate-delete pins, with 'AssertionError: expected [] to deeply equal [ \"f1\" ]' and 'expected { id: \"f1\" ... } to match object { id: \"f1\", status: \"deleted\" }' showing '+ \"status\": \"committed\"'. by-id, update and wiring pins stayed green. Restore leg: byte-identical, git hash-object 8ecd3650e4dd572d7c23d6d690bb7c04e5d0e560 before and after the reachability instrumentation; objectql/src/engine.ts restored to 40da9584dd9c2824855938c699d8bb8a5c876ab7 after the resolution control, rebuilt, marker ABSENT from dist (grep -c = 0) and dist/index.d.ts restored. (4) RESOLUTION PROVED, not asserted, in both directions: mutating the SUBJECT src with no rebuild changed the suite (the ablation above) => the subject resolves through src/. Poisoning objectql SRC with a throw at the top of delete() and NOT rebuilding left 47/47 GREEN with the poison never observed (0 hits) => the engine does not come from src; rebuilding that same poison into objectql dist turned 6 wired tests RED with the poison observed 6 times => it comes from dist, and the instrument can fail. That matches KNOWN_UNALIASED_TEST_IMPORTS, which lists @objectstack/objectql as unaliased for this package. (5) GATES, 18 families, exit code captured before any pipe, quoting each gate's own verdict line: changeset-gate-self-tests 0, objectui-changeset 0, slot-lookup 0, test-source-alias 0, type-source-resolution 0, adr-0087-registration 0 (run AFTER the commit, so it read the changeset from git as intended), changeset-no-major 0, ci-filter-parity 0, empty-changeset 0, plugin-teardown-shape 0, affected-docs 0, query-options-erasure 0, type-check-coverage 0, engine-double-contract 0, where-matcher 0, i18n 0, nul-bytes 0 ('check-nul-bytes: OK (scanned 6313 text file(s) ... no raw ASCII control bytes)'), type-check-debt --re-measure 0 ('check-type-check-coverage --re-measure: OK -- 33 ledger entr(ies) re-measured in 312.9s, 1908 raw tsc error(s) total, none above its recorded number').

Deliberately NOT done in this PR: it writes tombstones that become irreversible byte deletes 30 days later." ] }Reachability proof for the
MULTI_DELETE_RESOLVE_LIMITlimbTriage asked to confirm, not assume. Both branches of the live handler were instrumented with counters and every delete shape the engine offers was driven through the wired engine. The sibling id-branch is the positive control that proves the instrument can see a hit:
where: { id: { $in: [..] } }where: {}(match-all)where(unscoped)whereDelete requires an ID or options.multi=trueZero hits under test while the control fires on the very predicate path the branch was written for. Mechanism agrees on reading
engine.ts: all three sites that dispatchbeforeDeletebindinput.idto a scalar (by-id fromresolveEngineDeleteDispatch; per-row torow.id; the unscoped-multi dispatch reaches only registrations declaringdispatchUnscopedMultiWrite, which this file never did, and carries nowhereby definition). I claim it unreachable and removed it.Two predictions of mine were wrong and are recorded rather than smoothed over. I predicted
A=0for the unscopedmulti, no whereshape; it isA=2, because after the unscoped dispatch the engine continues into the per-row read with an unfiltered AST. And my first run of the$inshape showedA=0 B=0with the harness throwing — a stub-driver limitation, not an engine fact. I taught the probe stub$inand re-ran to close that hole, because leaving it would have meant claiming unreachability on the one shape the dead limb most plausibly served.Pin table with directions

git checkout -- attachment-lifecycle.tswhile the fix was still uncommitted, which restored the base file and silently discarded it (exit 0, no warning) — precisely the hazard the dev contract names. I re-applied it, re-ran to 405/405 green, and committed before resuming any reverse-verification. Nothing shipped from a half-restored tree: the ablation and both resolution controls above were re-run from the committed state, and the final tree is byte-verified.gh pr list ...and printed "OWNERSHIP SCAN DONE" with zero hits — butghis not on PATH in this container, so the loop never ran and read as a clearance.

PM 验收:ACCEPT —— PR #10951 已翻 ready + 武装 auto-merge
前提复现:两个动词摆在一起,一次运行
⭐ C 和 D 是这份复现里最有价值的两行:它们证明「墓碑机制本身是好的」,从而把缺陷精确定位到 delete 动词的 per-row 派发上,而不是留下「墓碑有时不写」这种没法据以修复的描述。
MULTI_DELETE_RESOLVE_LIMIT:不可达是测出来的分诊要求 confirm unreachability, don't assume it,我在派发里加了一句「证不出就别删」。他证了:六种可派发形态全部零命中,而阳性对照在每一种上都触发,再加上通读
engine.ts里全部三处beforeDelete派发点作为佐证。我核过
3fecc3eaa:STASH_KEY已彻底消失;MULTI_DELETE_RESOLVE_LIMIT只剩:180的一条注释,记录那条肢是什么、为什么随 stash 一起走、以及:202的佐证结论。代码删掉、理由留下——这正是删除该有的形状。⭐⭐ 他推翻了自己的两个预测,而第二个是本轮最值得记的一件事

$in探针跑出的是一个stub 驱动的局限,而它可以被读成一条引擎事实。他教会 stub 认$in后重跑,理由是他自己的原话:他发现自己的仪器局限恰好会制造出他想要的那个结论,然后去掉了那个局限。 这是今天整条流水线上最难的一种自查——不是「我测错了」,而是「我的测法恰好会让我的结论成立」。
解析路径双向证明,而且证明了仪器会失败
⭐ 最后半句是关键:一个从不变红的对照不是对照。他没有停在「绿了所以是 dist」,而是证明了同一装置能变红。这与
KNOWN_UNALIASED_TEST_IMPORTS的登记一致。两条他主动交代的过程失误
git checkout打在未提交的编辑上,把修复弄丢了一次 —— 正是我在派发里警告过的那个陷阱(fix(plugins,services): guarantee awarnchannel on twelve optional-errorsinks #10691 的 dev 也栽过同一个)。他重做了并说了出来。check-single-claim-paths类形状。他换第二种方法重做。两次都是"我的方法失效了而它看起来成功了",两次都自己发现并如实上报。这比不犯错更难,也更有用。
其余
check:i18n首轮PREREQUISITE NOT MET … Nothing was checked记为 NOT MEASURED,建 CLI 后重跑到真实 exit 0。该包没有typecheck脚本(--filter typecheck会零匹配 exit 0 什么也不说),改用包构建作为真实类型门 ——DTS Build success,BUILD_EXIT=0。class #10309 第 N 次:推导两个都没点名,均显式补跑。一处评审者会看到的接线变化已被点名:
sys_attachment现在只有一条beforeDelete注册(访问守卫那条)而不是两条,storage-service-plugin.test.ts里的一条 pin 随之移动。存量搁浅字节 → #10950
本修复是向前的:已经搁浅的
sys_file孤儿不被它清扫,而且它们不匹配任何一条已声明的清扫策略,所以没有任何东西会提名它们。已另立卡(unassigned、无pm:queue、带Blocked-by: #10240),并列出了修它必须先做的四个决定。⛔ 刻意不在本 PR 做,理由他写得很清楚:它写下的墓碑会在 30 天后变成不可逆的字节删除。 一次性清扫存量孤儿是一个需要裁决的动作,不是一次顺手的收尾。
