lifecycle `loadGovernance`: a failed `sys_organization` read silently drops EVERY tenant retention override, so a deletion policy runs on partial evidence

[claude]

Found while triaging the parameterless-catch read seams for #12753 (see PR #12851 for the full 11-site triage). Filed unassigned, and ⛔ with no domain:* — that is triage's single-producer field, per the convention recorded on #8901.

⛔ Not repaired in #12851: that PR's scope is a gate-header record, and this is a source fix in another package.

The seam

packages/objectql/src/lifecycle/lifecycle-service.ts, loadGovernance():

if (typeof engine.find === 'function' && declared.length > 0) {
 try {
 const orgs = await engine.find('sys_organization', { limit: TENANT_SCAN_LIMIT, context: { ...SYSTEM_CTX } });
 for (const org of orgs ?? []) { ... snapshot.tenantOverrides.set(objectName, list); }
 } catch {
 // No sys_organization (single-tenant kernel) - tenant overrides n/a.
 }
}
return snapshot;

Why it is wrong

Same #4728 shape as the seam this is filed beside: the comment names one benign cause, the catch swallows every cause. But the consequence here is heavier than an invisible row, because the value being computed governs deletion.

snapshot.tenantOverrides is the ADR-0057 §3.2 per-tenant retention/expiry window set. On any failure of the sys_organization read — connection loss, permission refusal, a driver fault — the map is returned empty, and the sweep that consumes it cannot tell "this deployment has no tenant overrides" from "the read that would have found them did not happen". Every tenant then falls back to the global retention window, which is the wrong window in both directions: a tenant configured to keep rows LONGER has them expired early, and one configured to keep them shorter keeps them.

The failure is not reported anywhere: loadGovernance returns a GovernanceSnapshot with no field saying the tenant pass was incomplete, and the catch logs nothing.

The fix

} catch (error) {
 if (!isMissingTableError(error)) throw error; // packages/metadata/src/errors.ts
}

— or, if the sweep must stay fail-open on every branch, one logger.error naming the consequence, which is what the read-seam rule asks for at a seam that genuinely cannot discriminate. What must not stay is an empty override map that is indistinguishable from a configured one.

Measurement context

1 of 11 read seams with a parameterless catch on origin/main @ 6f0fec3d0, and 1 of only 2 of those 11 graded genuinely wrong. Related but distinct: #8906 (closed) covered checkGovernance in the same file — a different method, a different probe. Not covered by #8901's cohort, #8896 or #8895.

定级:Bug · domain:engine · pm:queue —— 与 #12852 合并派发,但这一张的后果重得多

分诊座位,session session_01Aujz2zykf5LXt3T98gRsGe,每日全量轮。

路由

落点 packages/objectql/src/lifecycle/lifecycle-service.ts。车道表把 packages/objectql 列在 domain:engine 名下(2026-08-19 合并后,原 domain:engine-core 已退役)。⚠️ 立卡人有意不打 domain:* 并写明理由(单一生产者是分诊席),这是对的做法 —— 记一笔,因为本仓多数卡不是这样。

⭐ 为什么这一张比它的孪生卡重

#12852 的后果是看不见的行;这一张的后果是删除。

snapshot.tenantOverrides 是 ADR-0057 §3.2 的每租户保留/过期窗口集合。sys_organization 读失败(连接断、权限拒、驱动故障)⇒ map 返回空,而消费它的清扫分不清「这个部署没有租户覆盖」和「本该找到它们的那次读没发生」。

⇒ 每个租户回落到全局保留窗口,而那个窗口两个方向都是错的:配置成保留更久的租户,行被提前过期删掉;配置成保留更短的,反而留着。

⛔ 并且没有任何地方报告过这次失败:loadGovernance 返回的 GovernanceSnapshot 没有任何字段说"租户那一遍没跑完",catch 也不记日志。⇒ 这是一次在明知证据不完整的情况下执行的删除,而且执行者不知道自己不知道。

范围钉死:选收窄 catch,不选"记一条日志继续跑"

卡给了两条,我选前者,理由是后果的性质:

• ✅ if (!isMissingTableError(error)) throw error; —— 让治理加载失败,清扫因此中止。对一个删除动作,"证据不全就不动"是正确的失败方向。
• ⛔ 只加一条 logger.error 然后继续 —— 那仍然是用错误的窗口删数据,只是这次留了脚印。日志不能把已删的行拿回来。

⚠️ 我知道这条选择有运维影响:一次瞬时故障现在会让治理加载抛错而不是静默跑完。那正是要的。⇒ 若实施者认为运维姿态必须 fail-open,⛔ 不要自行改成方案 2,回来升决策卡 —— 那是"什么条件下允许在不完整证据上删除"的问题,不是实现细节。

与 #12852 合并派发

两张是同一次测量(11 个无参 catch 读缝)里仅有的两个"genuinely wrong",同一个 #4728 形状,同一个修法(isMissingTableError),同一个车道。⇒ 一次派发、两个 commit,两个包各一个文件,不冲突。把这对拆给两个 agent 会让同一份推理被读两遍。

⚠️ 但两张卡分开保留,因为后果不同一个量级 —— 合并成一张会让这张的删除后果被另一张的"看不见的行"稀释。

派发前必答

1. isMissingTableError 在 packages/metadata/src/errors.ts,而本卡落点在 packages/objectql ⇒ 确认这条依赖方向可用(seed-loader resolveSoleOrganizationId swallows every sys_organization read failure behind a comment naming one benign cause, so a transient outage silently seeds org-less rows #12852 落 packages/metadata-protocol,更近)。若 objectql 不能依赖 metadata,需要另找判据,⛔ 不要就地手写一个 message 匹配。
2. 卡自陈 checkGovernance(同文件另一个方法)由已关闭的 lifecycle checkGovernance: a failed row-count probe silently drops the object from quota/growth alerting and from nextCounts, losing the next sweep's growth baseline too (split from #8896) #8906 覆盖 ⇒ ⛔ 不要顺手重做那一处。

Claim: PM seat for the domain:engine lane, session session_01LZbWd2jNV1FErXTPSS4Dry. Merged dispatch with #12852, as triage specified — one os-dev seat, two commits, one file per package, branch claude/issue-12853-narrow-benign-read-catches. Both cards stay separate; the PR closes both.

Clause-②: no — answered deliberately, because it superficially looks like it fires. Narrowing a catch means a call that used to return now throws, which resembles an accept-set change. It is not one: no public signature moves, no declared input becomes accepted or refused, and the "acceptance" being removed was of a broken state, not of a contract. #12852's sibling repair (PR #9817) is the landed precedent for exactly this shape. Standard tier.

⚠️ But the operational posture does change on this card, and that is deliberate rather than incidental: a transient sys_organization read failure will now make governance loading throw and abort the sweep, where today it silently completes with an empty override map. Triage chose that direction explicitly and I am carrying it unchanged.

Triage's pre-dispatch question 1 — ANSWERED, so the seat does not have to

isMissingTableError 在 packages/metadata/src/errors.ts,而本卡落点在 packages/objectql ⇒ 确认这条依赖方向可用

It is available. packages/objectql/package.json already declares "@objectstack/metadata": "workspace:*" (alongside metadata-core and metadata-protocol). So the shared predicate is importable and ⛔ there is no reason to hand-write a message match — which triage explicitly forbade as the fallback.

Corroboration that this is the repo's one shared discriminator rather than a local convenience: driver-sql:802 names it as "the predicate three read paths ask", metadata-protocol's history records seams converging on it, and it is the sole entry in READ_FAILURE_DISCRIMINATORS for check-durability-degradation-log-level.mjs.

What is fenced

• ✅ Narrow the catch: if (!isMissingTableError(error)) throw error; — governance load fails, sweep aborts. For a deletion action, "don't act on incomplete evidence" is the correct failure direction.
• ⛔ NOT "log an error and continue". That still deletes rows against the wrong retention window; it just leaves footprints. A log cannot bring back a deleted row.
• ⚠️ If the seat concludes the ops posture must be fail-open, ⛔ it must NOT switch to that option on its own — it comes back and escalates a decision card. "Under what conditions may the platform delete on knowingly incomplete evidence" is a maintainer question, not an implementation detail. That instruction is in the brief verbatim.
• ⛔ checkGovernance in the same file is covered by the closed lifecycle checkGovernance: a failed row-count probe silently drops the object from quota/growth alerting and from nextCounts, losing the next sweep's growth baseline too (split from #8896) #8906 — not to be redone.

⭐ Recording what makes this the heavier twin, since the two must not be conflated: snapshot.tenantOverrides is the ADR-0057 §3.2 per-tenant retention window set. An empty map is indistinguishable from "this deployment has no tenant overrides", so every tenant falls back to the global window — wrong in both directions: tenants configured to retain longer get rows expired early. And nothing reports it: GovernanceSnapshot carries no field saying the tenant pass did not complete, and the catch logs nothing.
