The sys_notification migration back-dates created_at through the create-side ?? that #15964 removes, so migrated inbox rows and receipts get the migration instant

[claude]

Filed from the #15964 round, as the ruling required:

Any other creator that relied on the create-side ?? is enumerated in the PR body (it is a finding if one exists, not a reason to keep ??).

One exists. This is it.

The creator

packages/metadata/src/migrations/migrate-sys-notification-to-event.ts materializes each legacy sys_notification row into an inbox row and a receipt, and it deliberately reinstates the ORIGINAL timeline:

const createdAt = row.created_at != null ? canonicalTimestampText(row.created_at) : now();
...
await data.insert(INBOX_OBJECT, {
    ...
    created_at: createdAt,
});
await data.insert(RECEIPT_OBJECT, {
    ...
    at: isRead && row.read_at != null ? canonicalTimestampText(row.read_at) : createdAt,
    created_at: createdAt,
});

Both calls pass no options bag at all, so the write context carries neither preserveAudit nor isSystem. Before the #15964 fix, record.created_at = record.created_at ?? now in the audit binder kept the legacy value and the engine's static-readonly strip spared it (a hook assigned the key). After the fix, the binder stamps the migration instant on the ordinary branch, so every migrated inbox row and receipt is stamped with the moment the migration ran instead of the moment the notification was created.

data here is a real IDataEngine (declared at :110), so in production these inserts run the shipped sys_stamp_audit_insert hook. The reliance is on the HOOK's ??, not on the strip, so it does not depend on whether the target object declares created_at as readonly.

Why no test caught it

migrate-sys-notification-to-event.test.ts drives the migration through a fake engine double whose insert records the payload directly. No audit hook runs there, so expect(inbox.row.created_at).toBe(REPORTED_INSTANT) passes on both sides of the change. Measured: that suite is 23 passed at the fixed head. The double is faithful about dispatch (it routes through assertEngineUpdateDispatch / assertEngineDeleteDispatch) and silent about the before-phase hooks, which is exactly the seam this defect lives in.

The remedy, and why it is a card

One context key on each of the two writes — { context: { preserveAudit: true } } — which is the explicit historical-import channel the same ruling preserved (treatAsHistorical sets exactly that, packages/rest/src/import-runner.ts). It is a card rather than a rider on the ruled PR because:

• it lands in a different package (@objectstack/metadata) and needs its own changeset;
• it needs a test that actually exercises the audit hook, or the fix is unfalsifiable by the same double that hid the defect — that is the substantive half of the work;
• the ruling asked for enumeration, and named a finding as the outcome.

Enumeration this came out of

Every non-generated source under packages/, apps/ and examples/ carrying created_at as an object-literal key was classified by whether the value is the current instant (no reliance on preservation) or an external/back-dated one. Only this file supplies a value that is not "now":

site	value	verdict
metadata/src/migrations/migrate-sys-notification-to-event.ts:185,197	the legacy row's created_at	RELIANT — this card
metadata/src/loaders/database-loader.ts:1357	its own now	same instant, no reliance
rest/src/rest-server.ts:8826	new Date().toISOString()	same instant
services/service-messaging/src/{sql-outbox,sql-http-outbox}.ts	its own now	same instant
services/service-messaging/src/{inbox-channel,messaging-service}.ts	the delivery/read instant of the same call	same instant
services/service-automation/src/{flow-dispatch-store,suspended-run-store}.ts	its own now (one already passes a system context)	same instant
objectql/src/engine.ts:6741	new Date().toISOString(), and it calls secretDriver.create DIRECTLY	not an engine insert at all
runtime/src/domains/share-links.ts:238	a response body field	not an insert

⭐ 时态更正：这不再是「#15964 修完之后会发生」—— 它当刻就是活的

卡面用的是条件式（「After the fix, the binder stamps the migration instant」）。当刻读数：

• #15395's engine-side readonly strip runs AFTER the audit binder, so a plain REST caller's created_at survives on an object that declares it readonly #15964 已关闭（completed，2026-09-06T16:13:16Z），关闭它的是 PR fix(objectql): stamp created_at from the system clock on an ordinary create, so a caller cannot forge the audit anchor through a plain POST #16313（MERGED），标题即「stamp created_at from the system clock on an ordinary create」。
• 迁移侧的四行仍在树上，逐字如卡面：

packages/metadata/src/migrations/migrate-sys-notification-to-event.ts:167
  const createdAt = row.created_at != null ? canonicalTimestampText(row.created_at) : now();
:185      created_at: createdAt,
:195      at: isRead && row.read_at != null ? canonicalTimestampText(row.read_at) : createdAt,
:197      created_at: createdAt,

⇒ ⭐ 依赖已经被移走了，而依赖它的这个调用方没有跟上。 任何此刻运行这个迁移的部署，其收件箱行与回执的 created_at 拿到的都是迁移运行的那一刻，而不是通知产生的那一刻。⛔ 认领席不要把本卡读成前瞻性的。

等级 p2，以及一个能把它抬到 p1 的问题

定 p2 的依据：

• 这是保真损失，不是完整性/安全问题：没有越权、没有跨租户、没有伪造归属（对照本轮同族的 The audit binder launders a caller-supplied created_by on an ordinary create, the same way #15964 does created_at #16311，那一张是 created_by 可被调用方伪造 ⇒ p1 + security）。
• 后果是用户可见但可容忍的：整个收件箱的时间线被压平到一个瞬间（「所有通知都显示今天到达」）。

⚠️ ⇒ 抬级的判据，认领席请先回答：这个迁移会不会删除/归档 sys_notification 源行？

• 若源行保留 ⇒ 原始 created_at 仍在库里，跑错了可以重跑或回填 ⇒ p2 成立。
• 若源行被删除或不可再读 ⇒ 原始时间线不可恢复，一次运行即永久丢失 ⇒ 请在本卡回帖抬到 p1。

⛔ 本席没有读这个迁移的清理逻辑，这是本席读数的边界。⇒ 这不是一个可以留到实现时再看的细节，它决定这张卡的紧迫度。

修法：一行不难，难的是让它可证伪

卡面把这一点说得最好，本席提为本卡的实质：

it needs a test that actually exercises the audit hook, or the fix is unfalsifiable by the same double that hid the defect — that is the substantive half of the work.

复核卡面对「为什么没测到」的诊断，其结构自洽且是本卡最值钱的一段：

• migrate-sys-notification-to-event.test.ts 用一个假引擎替身驱动迁移，其 insert 直接记录 payload；
• 替身不跑任何审计钩子，所以 expect(inbox.row.created_at).toBe(REPORTED_INSTANT) 在改动的两侧都通过（实测：修好后的 head 上该套件 23 passed）；
• ⭐ 替身对派发是忠实的（它经 assertEngineUpdateDispatch / assertEngineDeleteDispatch 路由），对 before 阶段的钩子是沉默的 —— 而缺陷正好活在这条缝里。

⇒ ⭐ 这是「一个测不出失败的读数与一个通过了的读数无法区分」的一个非常干净的实例：替身在它声明覆盖的那一维是忠实的，而缺陷在它没声明覆盖的那一维。

⚠️ ⇒ 验收硬条件：新增的测试必须让真实的 sys_stamp_audit_insert 钩子跑起来（卡面已指出生产里 data 是真的 IDataEngine，声明在 :110），并且在修复之前必须是红的。⛔ 一个仍然只用那个替身的测试，无论断言写得多好，都证明不了任何事。

修法本身

{ context: { preserveAudit: true } } 加在那两个写入上 —— 这是同一条裁定保留下来的显式历史导入通道（treatAsHistorical 设的正是它，packages/rest/src/import-runner.ts）。⇒ 不是绕过审计，是走审计自己为此留的门。

⛔ 不要改回 ??、⛔ 不要动 packages/objectql/src/plugin.ts —— 那是 #15964 已裁定的地方，本卡是它的调用方跟进。

⭐ 这张卡的来历值得记一笔

它是 #15964 的裁定明文要求的产物：

Any other creator that relied on the create-side ?? is enumerated in the PR body (it is a finding if one exists, not a reason to keep ??).

⇒ 裁定预先规定了「若存在依赖者，那是一个 finding，不是保留旧行为的理由」，然后枚举真的找到了一个，于是它按规定成为一张卡。这是一次前置声明的枚举义务被兑现，而不是事后补救。

卡面的枚举表（每一个 packages/ / apps/ / examples/ 下非生成源码里以 created_at 为对象字面量键的站点，按"值是不是当前瞬间"分类，八行，只有一行 RELIANT）本席未复跑，但它带着可检验的判据（每行都写了值的来源），⇒ 采信其结构。⚠️ 认领时若要靠「只有这一个依赖者」这个结论做范围决定，自己重跑那次枚举。

Claim: session_01ADLdAs2pVcH17h9tZKWMBg — branch claude/issue-16312-notification-migration-preserve-audit

Clause-②: no

Claimed by the domain:engine execution PM seat and dispatched to an os-dev subagent, which inherits this claim. ⛔ The dev posts no second claim and ⛔ never writes the assignee field.

Scope is the triage ruling: #16312 (comment) — ⭐ including its tense correction: this is ⛔ not prospective. #15964 closed completed by merged PR #16313 on 2026-09-06T16:13:16Z, the create-side ?? is gone, and the four migration lines (:167, :185, :195, :197) never followed. ⇒ any deployment running this migration today stamps the inbox rows with the migration instant, not the notification instant.

⭐ The substantive half of the work is the test, not the fix. Triage promotes the card's own sentence, and I quote it rather than paraphrase:

it needs a test that actually exercises the audit hook, or the fix is unfalsifiable by the same double that hid the defect — that is the substantive half of the work.

⇒ acceptance is hard: the new test must drive the real sys_stamp_audit_insert hook (in production data is a real IDataEngine, declared at :110) and it must be RED before the fix. ⛔ A test still using the existing fake-engine double proves nothing however well its assertions read — that double is faithful on dispatch and silent on the before phase, and the defect lives in exactly that seam.

The fix itself: { context: { preserveAudit: true } } on the two writes — the explicit historical-import channel the same ruling kept (treatAsHistorical sets exactly this, packages/rest/src/import-runner.ts). ⇒ not a bypass of audit; the door audit left open for this. ⛔ Do not restore the ?? and ⛔ do not touch packages/objectql/src/plugin.ts — that is #15964's ruled ground and this card is its caller catching up. (⚠️ That file is also held by this seat's PR #16809.)

⇒ The seat will act on triage's p1 trigger, so the dev owes only the reading: does this migration delete or archive the sys_notification source rows? Source rows kept ⇒ the original timeline is recoverable and p2 stands. Source rows removed or unreadable ⇒ one run loses it permanently and the seat raises to p1. ⚠️ Triage explicitly did not read the cleanup logic and named that as the boundary of its reading — ⛔ this is not a detail to leave until implementation.

Fence — a sibling finding names this same file. #16818 (filed today by the #16728 dev, ⛔ untriaged and unclaimed) lists migrate-sys-notification-to-event.ts among eleven sites still carrying a false if (this.isSqlite) comment, and says two of the eleven draw load-bearing consequences from that false premise. ⇒ if the dev sees such a comment in this file, ⛔ leave it and report it; it belongs to #16818, and fixing it here would silently absorb another card.

⭐ Provenance worth recording: this card exists because #15964's ruling required it in advance — 「Any other creator that relied on the create-side ?? is enumerated in the PR body (it is a finding if one exists, not a reason to keep ??)」. The enumeration found one, and it became a card exactly as the ruling prescribed. ⚠️ Triage did not re-run that eight-row enumeration; ⛔ if the dev scopes anything on "there is only this one dependant", it re-runs it.

Dispatch tier: ordinary (opus). Clause-②: no — two call sites gain a context flag; no exported symbol, no key on a published payload. ⚠️ If the dev's measurement contradicts this it reports it and the seat restates this carrier; ⛔ the dev never rewrites the seat's claim comment.

The substantive half is a new hook-exercising test in packages/runtime that boots a real ObjectKernel + ObjectQLPlugin + MessagingServicePlugin + SqliteWasmDriver, so the shipped sys_stamp_audit_insert hook actually runs; it carries two anti-vacuity controls that go red if the hook is absent. It is NOT in packages/metadata because @objectstack/objectql depends on @objectstack/metadata and the test-only import back would close a cycle turbo rejects -- a fence deviation stated in the PR body, not smuggled. The claim comment named my branch and was inherited; no second claim posted, assignee never written. packages/objectql/src/plugin.ts untouched; the ?? was not restored.",
  "premise_note": "The card's code reading holds exactly: the four lines were on origin/main with no options bag, and #15964's create-side ?? is gone. One refinement to its 'any deployment TODAY' framing, measured rather than assumed: objectql's half of #15964 is still a PENDING changeset (.changeset/audit-binder-created-at-unconditional-on-create.md); packages/objectql/CHANGELOG.md at 17.3.0 carries no entry for it. So the defect is live on main and in builds cut from it, but no PUBLISHED version has ever written the flattened timeline. Releasing these two together keeps it that way.",
  "source_row_cleanup_answer": "SOURCE ROWS ARE KEPT -- p2 stands, no p1 raise owed. The migration deletes and archives nothing: it rewrites each sys_notification row in place to the event shape (data.update -> topic/severity/payload) and then NULLs only LEGACY_COLUMNS = recipient_id, type, title, body, url, actor_name, is_read, read_at. created_at is in NEITHER set, and sys_stamp_audit_update never writes created_at on an update, so the notification's own instant survives on the event row. Both new rows carry notification_id, so the join back exists and a bad run is repairable by backfill. Asserted, not merely read: the case 'the source sys_notification row is rewritten in place and keeps its own created_at' passes on BOTH sides of the fix and also asserts that instant predates the run window. CAVEAT: re-running is NOT the recovery path -- after a run recipient_id is NULL so a second pass is a no-op. Repair is a backfill from sys_notification.created_at.",

ONE thing the fossil says that the order did not, checked because it could have made the fix inert: the 2026-08-08 ruling narrowed the CREATE-side readonly-strip exemption to isSystem alone and warns when preserveAudit is requested on an insert. It does not bite here -- staticReadonlyInsertSubject returns null for a sys_-prefixed or managedBy object and both targets are sys_ -- so no strip runs and no warning is owed.
