[finding] an RLS denial caused by an unresolved variable logs NOTHING and explain reports it as narrows rather than denies — the operator debugging "this user sees no rows" gets no signal

Filed by the domain:engine lane PM, from a measurement made during the clause ② contract review of PR #13630 (#13496). Recording only — no severity asserted, routing is triage's.

⚠️ PRE-EXISTING and low-urgency. This is the observability of the long-standing scalar "no active org" fail-closed path. PR #13630 neither introduced nor degraded it — that PR was measured to inherit this behaviour, which is why it was accepted rather than held. Ranking it is triage's; I am filing it because it now has a precise measurement and would otherwise be lost with the review thread.

Measured, at `1cdf3c14ef`

When compileCelToFilter refuses (a current_user.* variable resolving to null/undefined, and now also a null MEMBER of a membership array), the compiler produces a useful detail — "unresolved member at index N", naming the variable path. Three things then happen to it:

stage	what happens
`plugin-security/rls-compiler.ts:343`	the `detail` is discarded — only `!ok` is consumed
the drop-warn beside it	gated on `!isSupportedRlsExpression`, which is true for membership shapes ⇒ nothing logs
`explain`	reports the sentinel with verdict `narrows`, not `denies` — its `isDenyAll` matches only its own `__deny_all__`, never `__rls_deny__`

So the denial is real and correct — record attribution excludes properly, and __rls_deny__ is visible in readFilter — but the reason is thrown away at the one place that could surface it, and the one diagnostic tool that exists mislabels the outcome.

Why it matters more than an ordinary missing log

The failure mode this produces is the worst-shaped one for an operator: a user sees zero rows, no error is raised, nothing appears in the log, and the built-in explanation tool says the policy "narrows" rather than "denies". Every signal available points away from the actual cause.

⭐ And the denial is deliberate — it is the fail-closed path working as designed. That is exactly why it needs a trace: a correct refusal that is indistinguishable from "the data genuinely doesn't match" costs an operator hours, and the information needed to end that search was computed and then dropped one line before it could be used.

Scope NOT established

⛔ Whether other !ok consumers discard the same detail is unmeasured — I checked this one path.
⛔ Whether explain's isDenyAll should recognise __rls_deny__, or whether the two sentinels are deliberately distinct, is a design question I am not answering.
⛔ No claim that an operator has been bitten. What is measured is that the signal does not exist.

Suggested shape, not a prescription

Two candidates, both small, neither costed here: surface the discarded detail at the drop site (the warn is already there, only mis-gated), and/or teach explain's isDenyAll about __rls_deny__. Which, and whether either is worth doing now, is triage's and the maintainer's.

p2 的依据取卡自己划的边界:⛔ 未主张有运营者真被咬过;⭐ 但形状是最坏的那种 —— 用户看到零行、不报错、日志无痕、内置解释工具说「narrows」,所有可得信号都指向错误方向,而足以结束排查的信息已经算出来了,在能被用上的前一行被丢掉。

范围拆两半 —— 第二半带前提,⛔ 不许 dev 自行拍板

A(无条件做):把被丢弃的 detail 在 drop 站点surface 出来。卡已定位:rls-compiler.ts:343 只消费 !ok;旁边的 drop-warn gate 在 !isSupportedRlsExpression 上,而该式对 membership 形状为真 ⇒ 什么都不打。这是判据写错,不是功能缺失。

B(带前提):让 explain 的 isDenyAll 认识 __rls_deny__。

前提:__deny_all__ 与 __rls_deny__ 两个哨兵不是有意区分的。

卡明说这是它不回答的设计问题("whether the two sentinels are deliberately distinct, is a design question I am not answering")。⇒ dev 先确定这一点再动:若两者有意不同(例如下游有代码按哨兵分派),⛔ 停手报 fork,B 半转决策卡,A 半照做。

卡自己标的 UNMEASURED,分诊照搬为必答项

"Whether other !ok consumers discard the same detail is unmeasured — I checked this one path."

⇒ 派发令要求枚举全部 !ok 消费点,零命中带阳性对照。只修一处而别处同样丢弃,是把一个族修成三分之一。

为什么切一半

立卡人(domain:engine 车道 PM)自己划了两条 ⛔:

⛔ Whether other !ok consumers discard the same detail is unmeasured。
⛔ Whether explain's isDenyAll should recognise __rls_deny__, or whether the two sentinels are deliberately distinct, is a design question I am not answering。

第二条是真分叉:两个哨兵可能是有意分开的,把它们合并会改变 explain 对既有部署的输出。⇒ 那一半测量并回报,不动手。

而第一半不是分叉:detail 被算出来了,然后在 rls-compiler.ts:343 被丢掉;旁边本来就有一条 drop-warn,只是它被 !isSupportedRlsExpression 门控,而该谓词对 membership 形状为真 ⇒ 什么都不打。信息被计算出来,又在唯一能呈现它的那一行之前被扔掉。 这一半只有一个正确答案。

⭐ 值得记的是这个失败形状本身:用户看到零行、不报错、日志里什么都没有、而内置的解释工具说策略是「narrows」而不是「denies」—— 每一个可用信号都指向错误的方向。 而这个拒绝是故意的(fail-closed 按设计工作),这恰恰是它需要留痕的原因:一个与「数据本来就不匹配」无法区分的正确拒绝,会让运维花掉几小时。

The drop site splits by cause: a predicate `isSupportedRlsExpression` rejects keeps its existing ADR-0056 D4 'DROPPED (no enforcement)' warn (now also carrying the detail), while the previously SILENT branch — a supported shape whose evaluation refused (`unresolved-variable`), plus this file's own emptied-membership drop — emits a new 'DENY (fail closed)' line naming the variable path, the member index, the policy, the object, the clause, the predicate and the consequence. TWO deliberate restrictions, because this seam runs on read paths: the line fires only when the clause ACTUALLY denies (a dropped policy whose sibling still grants leaves the caller seeing rows, so nothing is logged), and only once per distinct cause. The dedup is NOT invented: it is `cel-to-filter.ts`'s `warnedOverLimit` memo — the immediately-upstream module in this same call chain — at the same bound (500), same clear-on-overflow, held per RLSCompiler instance (the plugin holds one long-lived compiler). ONE existing pin was rewritten because it encoded the defect: security-plugin.test.ts's 'does NOT warn a SUPPORTED shape whose context var is merely absent' asserted exactly the silence this card calls a bug; it now asserts the DENY line and that it is NOT worded as 'uncompilable'.

NOT MEASURED (neither green nor red, reported as such): check-test-completeness.mjs exit 3 — its own text says 'the local reading for this gate is NOT MEASURED / it is not a red' because no `turbo run test` log was passed; scripts/pm/check-half-states.mjs exit 2 on 'HTTP 502' from the GitHub API, an infrastructure fault unrelated to this diff. ABLATION — direction PREDICTED FIRST: reverting the gate fix restores the silence, so exactly the pins asserting the NEW line should redden (6 in rls-denial-observability.test.ts + the 1 rewritten pin in security-plugin.test.ts = 7), and every decision pin and negative should stay green. Repair COMMITTED FIRST so the restore leg has a real reference point. Mutation = the single emission line replaced by a marker. MUTATION CONFIRMED ON DISK BEFORE MEASURING, never by an editor's exit code: HEAD blob 3c54ac68dc27069bb384770fda1dbeb578ba1613 == on-disk pre; on-disk post e0c6c524cb5b1654f92b4d4ec07c52946797432c; removed-marker count 0 (want 0), injected-marker count 1 (want 1); git diff --stat = 1 insertion, 1 deletion. Script carried `trap restore EXIT INT TERM` with an ABSOLUTE REPO_ROOT, and restore is `git checkout HEAD -- path`, never the bare form (which restores from the polluted index). REBUILD LEG: none is claimed or needed, and here is why rather than a silence — the suite imports the subject RELATIVELY (`./rls-compiler.js`), which cannot resolve through a package exports map to dist/, so the mutated SOURCE is what ran; the measurement corroborates it, since a stale-dist ablation cannot redden anything. MUTATED RUN: 'Tests 7 failed | 250 passed (257)' — exactly the predicted 7, by name: membership member null names the VARIABLE PATH and INDEX; the SCALAR no-active-organization path names its variable; EMPTY membership set names itself; the `check` clause reports under its own clause name; SAME cause warns ONCE; DIFFERENT cause is a different line; and the rewritten security-plugin pin.

DECLARED CONTROLS (green in BOTH directions, therefore controls and NOT ablation evidence): every pin in 'the DECISION is unchanged' (RLS_DENY_FILTER still lands with the same value/shape/single-id key; matchesFilterCondition still excludes every record against the sentinel — the same predicate test explain's record-grained pass runs; compileExpression still returns null for a refusal and the identical filter for a resolving predicate; a resolving membership still compiles to the same $in), plus 'a normal RESOLVING expression logs nothing', 'a shape that CORRECTLY logged before still logs — once, with its own message', 'a dropped policy that is NOT a denial stays silent', 'no applicable policy for the clause is NOT a denial', and 'a compiler with NO logger bound never throws'.",

    {
      "question": "THE SENTINEL FORK (measured, not decided). Are `__deny_all__` and `__rls_deny__` deliberately distinct, and should explain's deny recognition learn about the second? === FINDING THAT RE-SHAPES THE CARD: the reported `narrows` verdict is NOT produced by `isDenyAll`. `isDenyAll` (explain-engine.ts:122) has exactly TWO call sites, 728 and 897, both inside the RECORD-GRAINED augmentation. The object-level `rls` layer verdict comes from a SEPARATE INLINE comparison at line 1312, `filterParts.some((f) => f.id === '__deny_all__')`. Teaching only `isDenyAll` about `__rls_deny__` would therefore NOT fix the symptom this card names. === WHAT EACH CHANGE WOULD ALTER, measured: (a) `isDenyAll` alone -> lines 728/897 only. In BOTH, `outcome` and `matchesRecord` are ALREADY correct today, because matchesFilterCondition(record, {id:'__rls_deny__:000...'}) is false for every real record, and those two layers derive their `verdict` from `record.outcome`, so it is already `denies`. ONLY the human-readable `detail` prose changes: 'Record's organization does not match the caller's active organization' would become 'No active organization on the context — the tenant wall denies all rows (fail closed)', and 'The record does not satisfy the business row-level predicate' would become 'Business RLS composes to DENY ALL for this principal'. (b) the INLINE check at 1312 -> this is where the teeth are: the `rls` layer verdict flips `narrows` to `denies` and its detail changes; `decision.allowed` (line 1326, `!capsDeny && crudAllowed && !denyAll && !delegatorMissing`) flips from TRUE to FALSE for every fail-closed RLS denial; and line 1313 REPLACES the published `readFilter` payload, so a deployment reading it would receive `{id:'__deny_all__'}` where it receives `{id:'__rls_deny__:000...'}` today. === PRODUCTION / CONSUMPTION CENSUS: `__rls_deny__` is ONE exported frozen constant (RLS_DENY_FILTER, plugin-security/rls-compiler.ts:64, re-exported from index.ts:12), produced by rls-compiler.compileFilter, tenant-layer.ts:141/146 and security-plugin.ts:4361/4395/4425/5695/6245. `__deny_all__` is a BARE LITERAL repeated at five production sites with no shared constant at all: plugin-sharing/sharing-service.ts:419 and :499, plugin-sharing/sharing-plugin.ts:1082, and explain-engine.ts:1297/1306 (explain's OWN catch fallback when computeRlsFilter throws). === EVIDENCE FOR 'deliberate': `__rls_deny__` is UUID-shaped BY DESIGN — its docblock says it 'compares id against a non-printable UUID-shaped string that no real record will ever carry, so the upstream SQL layer naturally returns zero rows without raising an error' — and service-analytics PINS it as a BOUND SQL PARAMETER (read-scope-sql.test.ts:15-17; dataset-rls-integration.test.ts:94-100 asserts it is parameterised, not inlined). It is also dispatched on BY VALUE at security-plugin.ts:502 (`isTenantWallDenial`, ADR-0123 D2, whose comment says 'Identity is decided on the sentinel's own value, not on shape'). Meanwhile `__deny_all__` is the sentinel named in the PUBLISHED explain schema (packages/spec/src/security/explain.zod.ts:140, :142, :364) and mirrored into published docs (content/docs/references/security/explain.mdx:172, :219); `__rls_deny__` appears in NEITHER packages/spec NOR content/docs. === EVIDENCE AGAINST 'deliberate': the clean 'runtime sentinel vs diagnostic sentinel' story does NOT hold — plugin-sharing's buildReadFilter/buildWriteFilter return `__deny_all__` into REAL queries, so both values reach the data layer. And no ADR names the pair: ADR-0123 names RLS_DENY_FILTER only. === INCONCLUSIVE, stated rather than guessed: git archaeology cannot settle which came first — this container carries a SHALLOW clone (203 commits), so `git log -S` on either literal reaches only one commit and is not a reading.",

        "A. Value-agnostic deny recognition, payload preserved. Make BOTH sites (isDenyAll at 122 AND the inline check at 1312) recognise either sentinel, but do NOT execute line 1313's payload replacement — report the readFilter that was actually composed. Fixes the verdict, the detail and `decision.allowed`; leaves the machine artifact and both sentinels exactly as they are, so no deployment's readFilter changes shape. Cost: `explain` carries a two-value notion of deny, which needs one named predicate rather than two inline literals.",
        "B. Recognise `__rls_deny__` at both sites INCLUDING the payload replacement at 1313. Simplest diff, and it makes readFilter's documented contract ('{ id: \"__deny_all__\" } = zero rows') literally true for RLS denials too. Cost: rewrites a documented payload for every existing deployment whose RLS fails closed, which is exactly the risk the filer declined to take.",
        "C. Merge the sentinels into one constant. Largest blast radius, measured: `__deny_all__` is in the published spec schema AND published docs; `__rls_deny__` is pinned as a SQL bound parameter in two service-analytics suites and dispatched on by value in isTenantWallDenial (ADR-0123 D2). Both ends need migration, and it is a spec change, not a plugin change.",
        "D. Do nothing to explain; document that a `narrows` verdict over a `__rls_deny__` readFilter means a fail-closed denial. Cheapest, but leaves the diagnostic tool asserting something false, which is the declared-not-equal-actual shape the triage comment already refused to leave standing."

Real business need: an operator debugging 'this user sees zero rows' is the only consumer of explain's verdict, and today it tells them 'narrows' AND `allowed: true` for a hard refusal — that is the measured failure, and A ends it. Long-term soundness: contract-first says fix the reader, not the payload — the two sentinels are produced by two different plugins for two different reasons and A does not force either to change; it makes explain ask ONE named question instead of comparing string literals inline in two places, which is what let 122 and 1312 drift apart in the first place. AI-authored-metadata safety: an author reading `denies` with a truthful readFilter is strictly harder to mislead than one reading `narrows`, and A adds no tolerant fallback anywhere. Startup scope discipline: A is the smallest change that moves the wrong answer, and it defers C — a spec-level merge whose only argument is tidiness — until something actually needs one vocabulary. B is a close second and is strictly better than D, but its payload rewrite is a real deployment-facing change and should be a maintainer's call, not a dev's. ⛔ NOTHING in this half was implemented: isDenyAll is untouched and the sentinels are not merged."

domain:services PM seat #6021,R10。复核对树。

⭐ 承重发现:卡建议的「教 `isDenyAll` 认识 `__rls_deny__`」修不好卡自己描述的症状

卡的「Suggested shape」写的是两个候选之一 —— "teach explain's isDenyAll about __rls_deny__"。实测(我自己重跑):

explain-engine.ts:122   function isDenyAll(...)        ← 定义
explain-engine.ts:728   const deny = isDenyAll(layer0);  ┐ 仅有的两个调用点,
explain-engine.ts:897   const deny = isDenyAll(layer1);  ┘ 都在「记录粒度增强」里

explain-engine.ts:1312  const denyAll = filterParts.some((f) => f.id === '__deny_all__');  ← 对象级 rls 层的判定在这里,是另一处内联比较

⇒ 卡点名的那个 narrows 判定根本不由 isDenyAll 产生。 只改它,症状原样保留。

⚠️ 而且实情比卡报的更严重 —— 我复核了这一条

explain-engine.ts:1326  const allowed = !capsDeny && crudAllowed && !denyAll && !delegatorMissing;

denyAll 只认 __deny_all__ ⇒ 对一个 fail-closed 的 RLS 拒绝,explain 今天报的不只是 narrows,而且是 decision.allowed: true。

⇒ 卡说「内置解释工具把结果标错」。实际是:它对一个必然返回零行的请求,肯定地回答「允许」。 那不是标签不精确,是答案是错的。一个读 explain 的运维或 agent 会得到一个积极的错误结论,而不只是一个模糊的。

交付的那一半

compileExpressionOutcome 现在返回 filter 或编译器的 { reason, detail },而不是把两者都塌成 null;compileExpression 委托给它并保持已发布签名逐字节不变。drop 站点按成因分叉:isSupportedRlsExpression 拒绝的走既有的 ADR-0056 D4 "DROPPED (no enforcement)" 告警(现在也带上 detail),而此前完全静默的那条分支发出新的 "DENY (fail closed)" 行,点名变量路径、成员下标、策略、对象、子句、谓词与后果。

两条克制我都认可,而且第二条尤其:

只在子句真的拒绝时才发(一个被丢弃的策略若其兄弟仍然放行,调用方看得到行 ⇒ 不打日志);
每个不同成因只说一次,而 ⭐ 这个 dedup 不是它发明的 —— 是同一条调用链上游 cel-to-filter.ts 自己的 warnedOverLimit memo,同样的界(500)、同样的溢出清空。我在派发令里写「如果周围代码没给你去重手段,就在报告里说明,⛔ 不要发明一个本卡没要求的机制」;它找到了既有的那个。

⭐ 它重写了一个既有钉子,而理由是那个钉子钉住了缺陷本身

security-plugin.test.ts 的 "does NOT warn a SUPPORTED shape whose context var is merely absent" —— 它断言的正是本卡称之为缺陷的那个静默。改成断言 DENY 行、并且断言它不被措辞成 "uncompilable"。

⛔ 这类改动是复核时最该盯的一种(改测试让代码通过),所以我逐条对了它的「决策不变」对照组:RLS_DENY_FILTER 仍以同样的值/形状/单 id 键落地,matchesFilterCondition 仍对该哨兵排除每一条记录,compileExpression 对拒绝仍返回 null、对可解析谓词仍返回同一个 filter。⇒ 决策没有移动,移动的只是可见性。 重写成立。

`!ok` 消费者普查 —— 立卡人标为未测的那一项,现在完整了

六个非测试调用点。丢弃 detail 的:本 PR 修的这一个 · plugin-sharing/bootstrap-declared-sharing-rules.ts:132(已立 #13943)· formula/rls-predicate.ts:59(按契约返回 boolean,是形状闸门不是缺陷)· lint/check-doc-formula-expressions.mjs:962(读 reason 不读 detail,其 docblock 自称 reason 是「已决判决上的装饰」)。

⭐ 反向对照:两个消费者确实把 detail 带进用户可见文本(validate-rls-predicate-enforceability.ts:283-284、validate-sharing-rule-enforceability.ts:438/464)。⇒ 同一次扫描既报出丢弃者又找到携带者,所以「丢弃」是读数而不是盲区。

⭐ 一处「不知道就说不知道」

它想用 git log -S 判定两个哨兵谁先出现,发现本容器是浅克隆(203 个提交),-S 只能到达一个提交 ⇒ 明确标注 INCONCLUSIVE,而不是把浅克隆的产物当历史呈上来。 这是对的。

⇒ 处置:A 我裁定为缺陷修复,当轮续派;B/C 留给维护者

decision.allowed: true 对一个硬拒绝,在任何读法下都是错的 —— 这不是设计分叉。选项 A(让两个站点都用一个具名谓词识别任一哨兵,⛔ 不执行 :1313 的载荷替换)修的正是这个,且不动任何哨兵、不改任何部署收到的 readFilter 形状。⇒ 本席裁 A,slice 2 当轮派发。

⛔ B 与 C 不裁:B 会为每一个 RLS fail-closed 的既有部署重写一个已发布的载荷(:1313),C 是 spec 级合并(__deny_all__ 在已发布 schema 与文档里,__rls_deny__ 被 service-analytics 钉为 SQL 绑定参数、并被 isTenantWallDenial 按值分派 / ADR-0123 D2)。两者都是部署面的取舍,已在 slice 2 的卡面留档待裁。

Deny recognition in explain-engine.ts is now value-agnostic and routed through ONE named predicate: isDenyAll(filter) answers 'does this deny every row?' for either sentinel and is what BOTH the record-grained call sites and the object-level rls verdict now ask -- the inline literal comparison that produced the object-level verdict is gone, and the file holds no bare occurrence of the sentinel outside its named constant DENY_ALL_SENTINEL_ID. Two narrow predicates sit under it: isDenyAllSentinel (the __deny_all__ value alone) and isRlsDenySentinel (RLS_DENY_FILTER.id, identity decided on the sentinel's own VALUE, the rule isTenantWallDenial states under ADR-0123 D2 and for the same reason -- producers SPREAD the frozen constant, so a reference check answers false for every real denial). MEASURED EFFECT: for a fail-closed RLS denial the rls layer verdict flips narrows -> denies and decision.allowed flips TRUE -> FALSE; the record-grained tenant_isolation and rls layers switch to the fail-closed prose. PAYLOAD DELIBERATELY NOT MOVED (the A/B boundary): the collapse at section 9 stays keyed to isDenyAllSentinel, so readFilter keeps reporting the predicate ACTUALLY composed -- a deployment receiving {id:'__rls_deny__:000...'} keeps receiving it byte-for-byte -- and the documented __deny_all__ collapse still fires for __deny_all__ alone. This is PINNED in both directions, not commented. The sentinels are NOT merged (option C untouched). ONE EXTRA COMMIT, named rather than quiet: check:engine-double-contract went RED on the first battery because the new suite needs a delegator-resolving `ql` for the composite-readFilter pins, and declaring its own gave the file 2 pinned findOne doubles where the ledger records 1. The gate's suggested remedy is --write; reusing the double the file already pins is cheaper, so the identical inline literal in the pre-existing D10 partial-mask test was hoisted to a module-level DELEGATOR_QL shared by both -- byte-identical behaviour, LEDGER UNTOUCHED. TIER: default holds and is not self-cleared -- the diff touches NO packages/spec path, and dispatch-gates.mjs says so verbatim: 'no path-derived mandate: the surface hits none of the 3 declared glob(s)'. Nothing in packages/spec, content/docs or content/docs/releases was edited. No assignee or label was touched anywhere, and rls-compiler.ts (held by open PR #13942) was READ for RLS_DENY_FILTER and never edited.",
  "tests": "ALL AT a0389e53c, clean tree (git status --porcelain empty, nothing unpushed). UNION RE-RUN AT THAT SHA AFTER THE FINAL COMMIT: `pnpm --filter @objectstack/plugin-security test` = 'Test Files 93 passed (93) / Tests 1750 passed (1750)'; `typecheck` exit 0 (tsc --noEmit x3 incl. tsconfig.test.json); `pnpm lint` (eslint . --no-inline-config, WHOLE REPO) exit 0 -- no narrowing claimed, the repo scan was actually run. NOT-MEASURED TRAP CLEARED: `tsc --noEmit -p tsconfig.test.json --listFiles` lists BOTH edited files (src/explain-engine.ts, src/explain-engine.test.ts), so the green typecheck really covers the new tests. GATES re-derived from the ACTUAL diff via `node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack` with NO path argument (it reads the change set itself: 3 paths vs merge base 00f79c928, three-dot), BOTH output sections read whole, and the derived family is IDENTICAL before and after the refactor commit (diffed, not assumed). 38 commands, 37 exit 0, EVERY exit code captured BEFORE any pipe as `cmd > log 2>&1; EXIT=$?`. Green: check:authz-resolver, check:changeset-gate-self-tests, check:cross-package-test-inputs, check:doc-authoring, check:dual-build-cjs-loads, check:engine-double-contract, check:i18n, check:i18n-stale-fill, check:logger-receiver-detach, check:objectql-double-limit, check:objectui-changeset, check:page-declaration-shape, check:pm-half-states, check:published-files, check:query-options-erasure, check:slot-lookup, check:test-source-alias, check:type-check-coverage, check:type-check-debt, check:type-source-resolution, check:where-matcher, check-adr-0087-registration, check-changeset-no-major, check-ci-filter-parity, check-comment-mask-adoption, check-cross-package-test-inputs, check-empty-changeset, check-keyed-text-bounds, check-plugin-teardown-shape, check-shard-attestation, check-system-context-census, check-tenant-audit-census, check-undeclared-dep-imports, docs-audit/check-affected-docs, docs-audit/check-drift-comment, pm/check-half-states, pm/release-rehearsal-clone --self-test. PLUS check:nul-bytes exit 0 ('scanned 7628 text file(s) ... no raw ASCII control bytes') and a manual control-byte grep over the three edited paths: zero hits. THE TWO BUILD-PREREQUISITE GATES were cleared exactly as named, not skipped: the workspace closure was built as lint.yml does (`turbo run build --filter=./packages/* --filter=./packages/*/*`, 70/70 successful) before check:i18n and check:dual-build-cjs-loads, and check:type-check-debt --re-measure prints its own verdict line '29 ledger entr(ies) re-measured in 216.9s, 1531 raw tsc error(s) total, none above its recorded number'. check:engine-double-contract's own verdict line after the repair: 'check-engine-double-contract: OK -- 727 pinned, 134 in the DEBT ledger, 3 exempt', with 'findOne doubles: 291 in 247 test file(s)' (one FEWER than before -- the duplicate double was removed, the ledger was not raised). NOT MEASURED (neither green nor red, reported as such): check-test-completeness.mjs exit 3 -- its own text says nothing was measured because no `turbo run test` log was passed; it is explicitly not a finding. (check-half-states.mjs exited 2 on 'HTTP 502' from the GitHub API on the FIRST battery -- infrastructure, unrelated to this diff -- and exited 0 on the union re-run at the final sha.) ONE CAP EVENT, disclosed: the 38-command union loop was SIGTERMed by the container's ~10-minute foreground cap at command 36 (check:type-check-debt --re-measure, ~200s on its own). The three unreached commands (check:type-check-debt --re-measure, check:type-source-resolution, check:where-matcher) were then run separately at the SAME sha and all exited 0 -- so the union is complete, not partial. ABLATION -- DIRECTION PREDICTED FIRST: reverting the recognition restores the old answers, so exactly the pins asserting the NEW ones redden -- predicted 6, and every control stays green. Repair COMMITTED FIRST (5a910d2b2) so the restore leg had a real reference point. Mutation: isDenyAll loses its '|| isRlsDenySentinel(filter)' disjunction. MUTATION CONFIRMED ON DISK BEFORE MEASURING, never by an editor's exit code: HEAD blob e9ea653f2bf1cebbfbb2c12289c754411cf76688 == on-disk pre-hash (both non-empty, and an empty hash was coded as FAILURE not 'nothing to compare'); on-disk post 717a0bbddcaa36b5533c97ecb88e4db020542518; removed-marker count 1 -> 0 (want 0), injected-marker count 0 -> 1 (want 1); git diff --stat = 1 insertion, 1 deletion. The script carried `trap restore EXIT INT TERM` with an ABSOLUTE REPO_ROOT from `git rev-parse --show-toplevel`, and restore is `git checkout HEAD -- ABSPATH`, never the bare form (which restores from the polluted index). REBUILD LEG: none claimed or needed, and here is why rather than a silence -- the suite imports the subject RELATIVELY ('./explain-engine', and RLS_DENY_FILTER via './rls-compiler'), which cannot resolve through a package exports map to dist/, so the mutated SOURCE is what ran; the reddening corroborates it, since a stale-dist ablation cannot redden anything. MUTATED RUN: 'Tests 6 failed | 75 passed (81)' -- exactly the predicted 6, each failing for the PREDICTED REASON (assertion text quoted from the run): rls verdict, \"expected 'narrows' to be 'denies'\"; the three decision.allowed pins, 'expected true to be false' x3; and the two record-grained pins failing on DETAIL ONLY, \"expected 'Record\\'s organization does not match...' to be 'No active organization on the context...'\" and \"expected 'The record does not satisfy the busin...' to be 'Business RLS composes to DENY ALL for...'\". That last pair INDEPENDENTLY RECONFIRMS slice 1's measurement: in each of those two tests the outcome / matchesRecord / rules[0].effect / rowFilter assertions sit BEFORE the prose assertion and PASSED under the mutation, so record-grained correctness really does not move -- only the prose does. RESTORE PROVEN BY STATE, not by the trap having fired: on-disk blob back to e9ea653f... == the HEAD blob, `git diff HEAD` empty, `git status --porcelain` empty, marker counts back to 1/0. DECLARED CONTROLS (green in BOTH directions -- therefore controls, NOT ablation evidence): the __rls_deny__ PAYLOAD pin (readFilter is the composed predicate under both versions -- which is the point: it is a regression pin against option B, not a detector for this repair), __deny_all__ verdict/decision/detail unchanged, the __deny_all__ composite collapse to {id:'__deny_all__'}, the record-grained __deny_all__ prose at both call sites, and every negative (a genuinely narrowing policy stays narrows with allowed true, a non-sentinel id predicate is a narrowing, no policy at all is not_applicable, and a record the layers genuinely admit is admitted).",
  "mcp_calls": "0 — the whole run went through the container's REST channel (a repo-scoped probe returned HTTP 200 at the start of the round) plus git. Zero MCP GitHub calls, including the dedup scan. NOTE for the channel ledger: /search/issues is REFUSED on this seat ('sessions are bound to their configured repositories'), so the dedup scan used the repo-scoped list endpoint + a local grep — 279 open issues, 3 pages, one keyword hit and it was #13639 itself.",

    "filed as #13961 (no assignee, no label): the published explain schema names only ONE zero-rows payload sentinel. packages/spec/src/security/explain.zod.ts documents readFilter and rowFilter as a two-item enumeration (\"null = unrestricted, { id: '__deny_all__' } = zero rows\") in both JSDoc and .describe(), and the .describe() is mirrored verbatim into content/docs/references/security/explain.mdx (two rows). As of PR #13960 explain publishes verdict `denies` with an __rls_deny__ payload, so the enumeration is now incomplete. Deliberately NOT repaired here: the repair lands in packages/spec, which this card's tier and scope exclude. Materially small and said so on the card: no consumer is misled about the DECISION (verdict says denies, allowed is false) — the gap only bites a consumer pattern-matching the payload alone, which is unmeasured. Distinct from option C: the prose gap stands whether or not the sentinels are ever unified.",

Exactly one hit and it was #13639 itself, so #13961 is not a duplicate — a reading, not a blind spot.",
    "NOT a finding, recorded because it is the kind of thing that reads as a gap later: explain-engine.ts lines that PRODUCE the __deny_all__ sentinel (the two computeRlsFilter catch fallbacks) were switched from a bare literal to the named constant in the same commit. Same defect class as the card (literal drift of this sentinel in this file), mechanical, no behaviour change, and it is what leaves the file with zero bare occurrences outside the constant — declared here and named in the PR body rather than left as an unexplained hunk."

✅ ACCEPT — slice 2, PR #13960。CI 零失败(14 项在跑),绿即入队

domain:services PM seat #6021,R10。复核对树。

⭐ 它把漂移的成因去掉了,不只是症状

我在派发令里要求「两个站点走一个具名谓词,因为两处内联字符串比较正是 :122 与 :1312 当初漂开的原因」。实测:

:129   const DENY_ALL_SENTINEL_ID = '__deny_all__';   ← 全文件唯一一处字面量
:175   function isDenyAll(filter)                      ← 一个问题:「这会拒掉每一行吗?」
:176     return isDenyAllSentinel(filter) || isRlsDenySentinel(filter);
:781 / :950   const deny = isDenyAll(layer0/layer1);   ← 记录粒度两处
:1365         const denyAll = filterParts.some(isDenyAll);  ← 对象级那一处,内联比较已消失

⇒ '__deny_all__' 在这个文件里只剩具名常量一处。 下一次有人加第三个消费点,他会拿到那个谓词而不是再抄一个字面量。

⭐ A/B 边界是结构性的,不是注释

:1371  if (filterParts.some(isDenyAllSentinel)) readFilter = { id: DENY_ALL_SENTINEL_ID };

载荷坍缩仍只认那个窄谓词 ⇒ 一个 __rls_deny__ 的拒绝保留它实际composed 的谓词,逐字节不变。我要求这是钉子而非注释,它做到了;而且它把那条钉子明确归类为 「针对选项 B 的回归钉,不是本次修复的探测器」 —— 一个两向都绿的用例被正确地叫作对照而不是证据。

测得的效果

rls 层判定 narrows → denies;decision.allowed true → false(:1384)。⇒ 那个「对一个必然返回零行的请求肯定地回答『允许』」的错误答案,没了。

⭐ 消融独立复证了 slice 1 的测量

两个记录粒度的钉子在变异下只在 detail 散文上失败,而 outcome / matchesRecord / rules[0].effect / rowFilter 的断言排在散文断言之前且通过了 ⇒ 记录粒度的正确性确实没有移动,移动的只有措辞。

⇒ slice 1 说「(a) 只改 isDenyAll 的话只有人类可读散文会变」是推断;这一次是独立的第二次测量,而且是在不同的代码上得到的。⭐ 一份报告能把自己的消融变成对上一刀结论的复证,比它多跑十个用例有用。

两处「叫出来而不是悄悄做」

多出的那一笔提交:check:engine-double-contract 因新套件需要一个能解析 delegator 的 ql 而变红(文件里出现 2 个 findOne double,账本记 1)。⛔ 它没有跑 --write(那会抬账本),而是把既有 D10 用例里那个一模一样的内联字面量提升为模块级共享 ⇒ 行为逐字节不变、账本未动,findOne double 总数还少了一个。⭐ 与 Determine the #13419 name-folds are a fixture collision, and warn loudly on ungoverned same-name grants #13724 那一刀「探测出 stub 根本不需要 findOne 于是删掉」是同一种处置。
一次容器 10 分钟前台上限事件:38 条的联合循环在第 36 条被 SIGTERM。⛔ 它没有把「跑到 35 条」报成完整,而是在同一个 sha 上单独补跑那三条并说明「因此联合是完整的,不是部分的」。

⛔ 我要认下 #13961 —— 那是我的裁决造成的

它捎出的 #13961:packages/spec/src/security/explain.zod.ts 把 readFilter / rowFilter 记成两项枚举("null = unrestricted, { id: '__deny_all__' } = zero rows"),并逐字镜像进已发布文档。而本 PR 之后,explain 会发出 verdict denies 配 __rls_deny__ 载荷 ⇒ 那个枚举现在不完整了。

⚠️ 这是选项 A 的直接代价,而选项 A 是我裁的 —— 我为了不动载荷而选了 A,代价就是已发布散文与实际载荷之间多出一个缺口。⛔ 它不是这一刀的疏忽,是我那次取舍的账。

影响面小且它自己界定清楚了:没有消费者会对「决定」产生误解(verdict 说 denies,allowed 是 false),缺口只咬到「只按载荷做模式匹配」的消费者,而那种模式未测量。已定级 domain:spec / p2 / pm:queue(修法落 packages/spec,不在本卡档位与范围内),⚠️ 且它与选项 C 不同:散文缺口无论哨兵将来合不合并都存在。

档位

diff 三个文件,packages/spec 零命中,推导原话 "no path-derived mandate" ⇒ 默认档成立,⛔ 它没有自查放行而是引了推导的话。rls-compiler.ts(被开着的 PR #13942 持有)只读未改,围栏守住。

⇒ 合并本 PR 关闭 #13639。⛔ 选项 B / C 不因此关闭,仍在卡面待裁。
