[finding] two more `computeExecCtx` seams read "failed" and "not wired" as one value, and both feed authorization inputs — tenancy posture and the ADR-0069 auth gate

[claude]

Found while answering the mandatory enumeration on #13476 ("does this absorb pattern have a THIRD consumer that reads these two facts as one value?"). Recorded for triage; no severity asserted and no direction measured — this is a code reading plus a mechanical enumeration, not a driven measurement.

Method, and its positive control

Every seam inside RestServer.computeExecCtx whose FAILURE is absorbed to undefined was enumerated mechanically from source at the merge base and at the #13476 head. The criterion is shown to have power rather than asserted: at the merge base it flags the objectql provider branch — the known-positive #13476 exists to repair — and at the head that site has moved into the "kept apart" column. 10 absorb seams before, 9 after, 1 loud after.

The two that feed authorization

1. Tenancy posture

let tenancyPosture;
try {
    tenancyPosture = effectiveTenancyPosture(await kernel.getServiceAsync('tenancy') as any);
} catch {
    tenancyPosture = undefined;
}
const authz = await resolveAuthzContext({ ql, headers, getSession, tenancyPosture });

undefined means both "no tenancy service is registered" (true for single-tenant deployments) and "the tenancy service failed to resolve". It is an authorization input: resolveAuthzContext passes it to resolveApiKeyAdmission, and the Layer 0 wall refusal is conditional on it being present —

if (keyPrincipal?.tenantId && input.tenancyPosture) {
    const posture = input.tenancyPosture;
    if (postureEnforcesWall(posture) && !grants.accessible_org_ids.includes(keyPrincipal.tenantId)) {
        return { ..., authRefusal: { reason: 'organization_membership_ended', ... } };
    }
}

So when the value is absent the organization_membership_ended refusal does not run. Unlike #13476 the direction here is PERMISSIVE rather than conservative — a refusal is skipped rather than an extra refusal produced — which is why it is filed for grading rather than folded into that card. ⚠️ NOT MEASURED: no wiring was driven for this, and whether the condition is reachable in a real deployment is exactly what triage should establish first.

Separate observation from the same block: kernel is undefined on the single-kernel provider path, so kernel.getServiceAsync raises a TypeError that the same catch absorbs. On that path the posture is therefore ALWAYS undefined. Whether that is intended is worth confirming while this is open.

2. The ADR-0069 auth gate

let authGate: AuthGate | undefined;
try {
    if (typeof authService.isAuthGateActive === 'function' && authService.isAuthGateActive()) {
        const gatedSession: any = await getSession(headers).catch(() => undefined);
        authGate = normalizeAuthGate(gatedSession?.user) ?? undefined;
    }
} catch { /* gate is best-effort - never break context resolution */ }

authGate stays undefined both when no gate is active (the common, correct case) and when the probe or the session re-read FAILED. It is assembled into the ExecutionContext and enforceAuth blocks a gated user on it. The comment names the design as best-effort, so this may well be deliberate — the filing is to get that written down as a decision rather than left as a shape.

A third, non-authorization instance, for completeness

The settings seam absorbs the same way and feeds resolveLocalizationContext. Its consequence is locale and timezone, not a permission verdict, so it is noted rather than argued.

Explicitly NOT part of this

The auth-service seams and the getSession swallow collapse the same way, but they are already recorded as the CONTEXT-LOST degrade in #13255 and are not re-filed here.

Related, and distinct

• [finding] after the #13279 repair, an UNRESOLVABLE data engine still answers 403 FORBIDDEN — the last surviving GRANTS-LOST disguise at the package door #13476 — the data-engine instance, repaired.
• [finding] resolveExecCtx 的 .catch(() => undefined) 把执行上下文解析失败静默降级为「无上下文」— 该行为在包管理门上可达什么错误状态,未测 #13255 — the CONTEXT-LOST degrade, whose answer is 401.
• [finding] the shipped objectQLProvider in rest-api-plugin.ts absorbs before the transport sees it — the #13476 repair does not reach the single-kernel wiring #13904, [finding] getServiceAsync rejects identically for "service never registered" and "service failed to construct" — so a transport cannot tell an unwired embedder from a broken one #13905 — the two remaining halves of the data-engine seam.

⚠️ 这张卡与它的兄弟 #13476 / #13904 方向相反,这是它最重要的性质

#13476 和 #13904 记录的塌缩,方向是保守的:未知被答成拒绝(403/503),⛔ 没有越权面。

本卡记录的两处不是:

租户 posture(它的 undefined 跳过 Layer 0 的 organization_membership_ended 拒绝;⚠️ 而且在单内核 provider 路径上 kernel 是 undefined,所以那个 posture 永远是 undefined)与 ADR-0069 auth gate(一次失败的探测与一个未启用的 gate 不可区分)。

⇒ 方向是宽松的(PERMISSIVE) —— 一次失败可能表现为「这道检查不适用」,而不是「这道检查拒绝了你」。

⛔ 但它是 NOT MEASURED,而我拒绝把它当成已测

立卡的 dev 明确标注这是一次代码阅读、交给分诊定级的线索,⛔ 不是驱动出来的结果。本席原样保留这个区分,并且这是本卡的派发形状:

⇒ 第一交付物是把它变成一个读数,⛔ 不是修它。

具体要答的:

1. 那条宽松路径可达吗?驱动它 —— 让 posture 探测失败,看那道 Layer 0 拒绝是否真的被跳过。⛔ 不许从代码形状推断。
2. 「单内核 provider 路径上 posture 永远 undefined」这句话是否成立?若成立,那不是「失败时的边缘情况」,是常态,而那会改变本卡的整个性质。
3. auth gate 那半:一次失败的探测与一个未启用的 gate,在线上答案里真的不可区分吗?
4. ⭐ 每一条零命中都要阳性对照。 [finding] after the #13279 repair, an UNRESOLVABLE data engine still answers 403 FORBIDDEN — the last surviving GRANTS-LOST disguise at the package door #13476 的 dev 立了标杆:它对枚举判据本身做了对照(在合并基上判据能命中那个已知阳性),⇒ 照做。

⚠️ 若测出它不可达,那也是完整答案,而且是好答案——把一条「读起来吓人」的代码路径降级成有据的非问题,值一次派发。⛔ 不许因为「没找到」就悄悄改成修一改了事。

⛔ 定级说明:p2 是待测量的定级,不是结论

若上面第 1 或第 2 条测出可达,尤其第 2 条(常态而非边缘),⇒ 回来重新定级,那时它可能是 p1 且带 security。⛔ 本席现在不预先抬级:一次代码阅读不足以支撑一个安全等级,而一个基于未测量读数的 p1 会挤掉真正测过的活。

⭐ 反过来也要说清楚:⛔ 也不许因为它现在是 p2 就把它当小事排到队尾。 它是今天这一族里唯一方向宽松的一条,而那正是它需要被测的理由。

围栏

⚠️ 落点在 computeExecCtx,即 packages/rest/src/rest-server.ts —— 该文件当前由 PR #13910(#13476)持有,而那个 PR 停泊在 clause ② 上。

Blocked-by: #13095

Serial re-pointed, not newly imposed. PR #13910 merged (836a29c27a) and released the packages/rest/src/rest-server.ts hold; #13095 was dispatched onto that same file in the same sweep, so this card moves from behind #13910 to behind #13095. Ruling ① — same file, hard serial, ⛔ no region exemption.

⚠️ Relevant to this card specifically: computeExecCtx — the seam this card is about — lives in rest-server.ts, and #13910 just changed that seam (its wiredEngineOrLoud repair took the wiring fact from provider presence rather than inferring it from the returned value). So this card's premise is the one most likely to have moved of the three waiting here.

Restart-when: #13095's PR merges — not when it is armed. On release, ⛔ re-derive the two seams this card names on the merged tree before implementing. #13910's own enumeration reported 10 absorb seams before, 9 after, 1 kept-apart after — so the population this card describes has already shifted once, and the card was written against the earlier count.
