analytics: a non-RLS getReadScope scope bypasses read-scope-sql on the ObjectQL engine path — driver-sql lowers $nin: [] to constant TRUE (whole table), so a lowering-site refusal cannot guard this route

Filed unassigned by the #13571 dev while measuring that card's PM mechanism assumption 1 ("check who actually calls this compiler"). Recording only — severity and routing are triage's. This finding is decision-material for #13571 but does not block it and is not resolved by it.

What was measured, on `eb64351`

ObjectQLStrategy merges StrategyContext.getReadScope output into the FilterCondition it hands the engine (packages/services/service-analytics/src/strategies/objectql-strategy.ts, the ctx.getReadScope(objectName) merge near the userFilter return, ~:601-602). On that execution path the scope never reaches compileScopedFilterToSql — read-scope-sql compiles the scope only on the NativeSQL path (applyReadScope) and for the /analytics/sql echo (generateSql).
driver-sql lowers $nin: [] via whereNotIn(field, []) wrapped null-safe (packages/drivers/driver-sql/src/sql-driver.ts, the $nin case near :13314) — constant TRUE. Live in-repo pin of the semantics: packages/services/service-analytics/src/__tests__/filter-normalizer-not-null-safe.test.ts:534 (stage: { $nin: [] } admits ALL rows on a real backend).
Consequence: a non-RLS getReadScope provider (StrategyContext.getReadScope is a spec contract — packages/spec/src/contracts/analytics-service.ts ~:385 carries a hand-written example) handing { f: { $nin: [] } } or { $not: { f: { $in: [] } } } gets the whole table on any query the ObjectQL strategy serves, regardless of what read-scope-sql's emptied-membership folds are polarity-dependent at the lowering site itself: $in: [] folds to 1 = 0 one arm from $not, and $nin: [] folds to 1 = 1 (constant TRUE) #13571 ships in read-scope-sql — a compile refusal there can only ever guard the NativeSQL path and the echo.

What keeps it from biting today

Identical protection profile to #13571's: in-repo the only scope producer is the RLS compiler, and since PR #13570 its polarity-aware guard drops both shapes before they are emitted; the CEL lowering never emits $nin at all. The vacancy is the same as #13571's, one strategy over: no mechanical guard stands between a spec-contract producer and the engine lowering.

#13571 (the lowering-site card — whatever disposition it lands covers the NativeSQL path + echo only) · #13552 / PR #13570 (the producer-side polarity guard) · #3597 (closed — ObjectQLStrategy not consuming getReadScope at all; this is the residue on the consuming side) · ADR-0021 (read-scope contract)

Triage: lands in packages/services/service-analytics/src/strategies/objectql-strategy.ts ⇒ domain:services, pm:queue, type Bug, priority:p1, security。

为什么 Bug 而不是 finding

StrategyContext.getReadScope 是spec 契约(packages/spec/src/contracts/analytics-service.ts,卡点名其 ~:385 带手写示例)⇒ 平台声明第三方可以提供 read scope。而在 ObjectQL strategy 这条路径上,该 scope 从不经过 compileScopedFilterToSql ⇒ 声明的读作用域在一条真实路径上不被强制。declared ≠ enforced,接受集不变 ⇒ Bug。

为什么 p1 + security

后果是整表泄露,不是降级:driver-sql 把 $nin: [] 经 whereNotIn(field, []) 降为常量 TRUE,而这个语义在仓内有活的 pin(filter-normalizer-not-null-safe.test.ts:534,stage: { $nin: [] } 在真实后端上放行全部行)⇒ 一个非 RLS 的 scope 提供方交出 { f: { $nin: [] } } 或 { $not: { f: { $in: [] } } },在这条 strategy 服务的任何查询上拿到整张表。

⚠️ 今天不咬人的原因必须写进派发令,否则会被误读成「不急」:仓内唯一的 scope 生产者是 RLS 编译器,而自 PR #13570 起它的极性感知守卫会在发出前丢掉这两种形状,CEL lowering 根本不发 $nin。⇒ 保护来自生产者侧的自律,不是消费者侧的门。 契约允许的第三方生产者面前,这里没有任何机械守卫。

⭐ 派发时必须与 #13571 一起读(读耦合,文件面不相交也挡不住)

卡说得很清楚,分诊逐字保留为约束:

"a compile refusal there can only ever guard the NativeSQL path and the echo"

⇒ #13571 无论落成什么,都不会修好本卡。 反向也成立:本卡是 #13571 的决策材料(它证明「在 lowering 站点拒绝」这个方案有一条它够不到的路径)。

⇒ 两卡不同批派发(同一 seam,读耦合),且先派 #13571 的裁决方向确定后再派本卡 —— 若 #13571 裁为「在更靠上的位置统一守」,本卡可能被整体吸收。派发前现读 #13571 的状态与裁决,⛔ 不沿用本卡写作时的描述。

必答项

本修复的正确位置是「ObjectQL strategy 合并 scope 之后、交给引擎之前」还是「driver-sql 不再把 $nin: [] 降为 TRUE」?两者不等价:后者会改变一个已有 pin 断言的语义(那条 pin 明确断言 $nin: [] 放行全部行)⇒ 若走后者,那条 pin 必须有意改写并说明,⛔ 不许静默修绿。dev 先给读数再选路。

  "summary": "Premise re-verified on origin/main before writing anything: measured against a real engine (driver-sqlite-wasm over driver-sql, ObjectQL aggregate route), a non-RLS getReadScope handing { owner: { $nin: [] } } admitted ALL THREE fixture rows, and so did { $not: { owner: { $in: [] } } }. Two further spellings measured to the same whole-table result and are NOT in the card: a bare [] comparand under $not, and a multi-key operator object { $in: [], $ne: 'x' } under $not. Repair: assertReadScopeCannotVacate(scope, objectName) exported from read-scope-sql.ts (next to the compiler whose #13571 disposition it matches, one file owning the whole ruling and one refusal envelope), called at ObjectQLStrategy.withReadScope right after getReadScope returns and BEFORE the $and merge and the provenance mark. It refuses an empty $nin at any polarity (matching compileOperator's own arm, which throws whatever encloses it) and an empty $in / bare [] only at inverted effective polarity, so the ruled $in: [] reduction and the live RLS composite are untouched. It is a walk, never a reduction, which is why polarity is readable here without re-opening the #5322 interaction the #13571 verdict asked to be ruled first. BOUNDED IN-PLACE SECOND SITE, declared: the same guard is called at ObjectQLStrategy.resolveFkAttr, the other getReadScope-to-engine merge in the same file (referenced object, FK-attribute expansion) - same defect class, one call, pinned by its own case with the base object's scope kept ordinary. Named in the PR body with its evidence. DECLARED CONSEQUENCE: for the $not-over-$in-empty spelling the ObjectQL echo (which still compiles) and the ObjectQL execution (which now refuses) disagree; the card forbade moving the echo, so this is documented in the module header and filed as #13926 rather than fixed here. TIER: clause 2's path limb does NOT fire - the diff touches no packages/spec path (4 files: one changeset, one new test, read-scope-sql.ts, objectql-strategy.ts); the change narrows, so the 2026-08-28 negative boundary does not apply either. PM HALF-STATE: #13640 is assigned to os-steve but carries NO claim comment with a session id and branch - only the triage comment. Reported per the claim protocol; work proceeded as dispatched. PLATFORM NOTE: the PR create appended a SECOND copy of the Claude Code footer; left alone because a PATCH would downgrade the session-URL footer to the bare form and lose the attribution.",
  "tests": "All on a050efce9, the head of the branch, and the union below was run on that exact commit (nothing changed after it; git status clean, git rev-parse --short HEAD = a050efce9).\n1) pnpm --filter @objectstack/service-analytics test -> 'Test Files 85 passed (85) / Tests 1837 passed (1837)', including #13649's read-scope-empty-nin-refusal.test.ts and every other read-scope pin.\n2) New pins: src/__tests__/objectql-read-scope-vacancy-refusal.test.ts, 18 cases, all green - six vacating spellings refused with READ_SCOPE_COMPILE_FAILED / 500 and the offending path named; harness control (no scope admits all rows) so a refusal assertion cannot pass on an empty fixture; the asymmetry ($in: [] still zero rows); both over-denial controls (the #13570 RLS composite still admits exactly the own row; the $and composite still denies); the ordinary case incl. a non-empty $nin keeping NULL-safety; the FK-resolution door with its ordinary-scope control; and an immobility block over compileScopedFilterToSql itself (both other routes consume that one function and have no other read-scope translation) asserting the empty-$nin refusal still carries ITS OWN #13571 message and not the guard's, that an ordinary scope still compiles to '\"deal\".\"owner\" = ?', that the ObjectQL echo still refuses through the compiler, and - labelled explicitly as an immobility control and NOT a contract - that $not over $in: [] still compiles there.\n3) typecheck: pnpm --filter @objectstack/service-analytics exec tsc --noEmit --listFiles -> no 'error TS' lines, and --listFiles shows BOTH edited sources AND the new test file inside the program (grep -c = 1 each), so the green covers the edits rather than merely running.\n4) ABLATION. Direction predicted before the run: reverting the two call sites reddens the six vacancy pins plus the FK-door pin and leaves every control green in both directions. The repair was COMMITTED FIRST; the mutation replaced the two anchored call lines and was CONFIRMED ON DISK before any measurement - CALLS_BEFORE=2, CALLS_AFTER=0, MARKERS=2, blob hash moved baeb0aee -> 48b7d597 (an editor exit code was not used as evidence); a trap with ABSOLUTE paths (REPO_ROOT from git rev-parse --show-toplevel) covered EXIT/INT/TERM. NO REBUILD LEG is claimed and none is owed: the test imports the subject by RELATIVE path inside its own package, so vitest transforms src/*.ts directly and there is no dist to reach. Result matched the prediction exactly: 'Tests 7 failed | 11 passed (18)', the first failure reading \"AssertionError: expected [ 'r1', 'r2', 'r3' ] to be undefined\" - the whole table. Restore PROVEN BY STATE, not by exit code: git checkout HEAD -- ABSOLUTE_PATH, then git diff HEAD empty, blob hash back to baeb0aee (HEAD blob, verified non-empty before mutating), 0 ablation markers left. The 11 that stayed green are DECLARED CONTROLS, not ablation evidence.\n5) GATES re-derived from the ACTUAL diff: node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack (no paths passed; both output sections read whole; no .mdx in the diff so no second derivation was owed). 35 commands (30 path-matched + convention-triggered). 34 GREEN, exit codes captured BEFORE any pipe (cmd > file 2>&1; EXIT=$?). The single exception is node scripts/check-test-completeness.mjs, EXIT=3 = PREREQUISITE NOT MET = NOT MEASURED (it grades a saved turbo test log only CI produces) - recorded as NOT MEASURED, never as a pass and never as a red. pnpm check:type-check-debt first refused for an unbuilt closure; I built exactly the closure it named (turbo run build --filter=./packages/* --filter=./packages/*/*, 70/70 tasks) and it then reported 'OK - 29 ledger entries re-measured, 1531 raw tsc errors total, none above its recorded number'. pnpm check:dual-build-cjs-loads green after the same build ('102 published require entry points across 66 packages load'). Also green: check:engine-double-contract, check:where-matcher, check:query-options-erasure, check:type-check-coverage, check:cross-package-test-inputs, check:dispatcher-error-vocabulary, check:test-source-alias, check:doc-authoring and the rest.\n6) REPO-WIDE, not narrowed: pnpm lint (eslint . --no-inline-config) ran to completion, exit 0, clean - no narrowing is claimed or needed. node scripts/check-nul-bytes.mjs OK over 7613 files, plus a direct control-byte grep over the four changed files (no match).\n7) Every heavy run went through bash scripts/pm/os-verify-lock.sh with OS_VERIFY_LOCK_SLOT=issue-13640 set before the first attempt; conclusions read from the VERDICT lines, never a bare $?.",

✅ ACCEPT — PR #13924。⏳ 绿即入队

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

⭐ 它没有停在代码阅读上,而是对着真引擎把泄漏跑出来了

卡本身是代码形状的推断。它在写任何代码前,用 driver-sqlite-wasm over driver-sql 走 ObjectQL aggregate 路线实测:一个非 RLS 的 getReadScope 交出 { owner: { $nin: [] } } ⇒ 三行 fixture 全部被放行;{ $not: { owner: { $in: [] } } } 同样。⇒ 前提从推断变成复现。

⭐ 而且它找到了卡里没有的另外四种拼法

我在派发令里写「只钉一种拼法会漏掉另一种,而卡点了两种」。它测出六种都通向整表:除卡里那两种,还有 $not 下的裸 [] 比较值,以及 $not 下的多键操作符对象 { $in: [], $ne: 'x' }。⇒ 我按卡面写的「两种」本身就是不完整的规格。

守卫的落点与形状,两条都是我要的

住在 read-scope-sql.ts(:545 export function assertReadScopeCannotVacate),紧挨着它要与之保持一致的那个 read-scope-sql's emptied-membership folds are polarity-dependent at the lowering site itself: $in: [] folds to 1 = 0 one arm from $not, and $nin: [] folds to 1 = 1 (constant TRUE) #13571 处置 ⇒ 一个文件拥有整条裁决、一个拒绝信封,而不是第二份措辞不同的意见。
调用在 objectql-strategy.ts:616,即 getReadScope 返回之后、$and 合并与来源标记之前。

⭐ 而它对极性的处理是这一刀最讲究的地方:空 $nin 在任何极性下都拒(与 compileOperator 自己那条臂一致),空 $in / 裸 [] 只在反转后的有效极性下拒 ⇒ 被裁定的 $in: [] 归约与线上的 RLS 复合式一个都没动。而这之所以可行,是因为它做的是遍历而非归约 —— 所以在这里读极性不会重开 #5322 那层交互(#13571 的裁定要求那层先被裁)。

声明的第二落点与声明的后果,两条我都采纳

有界就地第二处:同文件的 resolveFkAttr(:1099)是另一处 getReadScope→引擎的合并,同一缺陷类,一次调用,自带用例,基对象的 scope 保持普通。⇒ 属于有界就地修复,已在 PR 正文声明。
⚠️ 声明的后果:对 $not-over-$in-empty 这种拼法,ObjectQL 的 echo(仍编译) 与 执行(现在拒绝) 会不一致。我的派发令禁止动 echo,所以它记进模块头并立卡 analytics: read-scope-sql's ruled $not-over-$in-empty residue has no open card — and #13640 turned it into an echo-vs-execution disagreement on the ObjectQL strategy #13926,⛔ 没有偷偷扩范围。我裁定这可接受:执行侧拒绝 ⇒ 无泄漏,分歧只影响 /analytics/sql 预览的真实性而非安全性;但它必须被跟踪,而它已经被跟踪。

边界与档位

⛔ 未动 driver-sql 的通用 $nin: [] lowering(我明令禁止的那把大锤);⛔ 未重裁 #5322;⛔ 未削弱 #13570 的生产者侧守卫。档位:diff 四个文件,packages/spec 零命中 ⇒ 路径肢不触发;方向是收窄 ⇒ 负边界不适用。默认档成立。

钉子里有一块我特别认可

那 18 个用例里有一个不动性区块,断言 compileScopedFilterToSql 自己没被这次改动影响 —— 包括「空 $nin 的拒绝仍带它自己的 #13571 消息而不是新守卫的消息」。⇒ 这防的是「两条路各自拒绝、但错误信息互相污染」,而那种污染在排查时比缺陷本身更费时间。另外「$not over $in: [] 在编译器里仍然编译」被显式标注为不动性对照而非契约,这个区分是对的。
