security: the analytics ObjectQL execute face answers a row-level read scope it cannot run with INVALID_FILTER / 400 whose message echoes the policy's field name and comparands — the disclosure #5367 closed for the native / echo faces #19995

Filing gate ① — a product defect with a named site and a measurement (class b: a declared contract, the #5367 ruling recorded in read-scope-sql.ts's header, not held on a sibling face).

The contract

The #5367 ruling, recorded in packages/services/service-analytics/src/read-scope-sql.ts's header: a read-scope refusal is deliberately ⛔ never a 4xx. A 400 echoes its message verbatim and hands the caller 「the FIELD NAMES AND COMPARANDS OF THE RLS POLICY — the one document a tenant must not be able to read out of an error body」. The native-SQL and echo faces hold this: they return READ_SCOPE_COMPILE_FAILED / 500 with the message withheld.

The defect

The ObjectQL execute face composes the same read scope into the engine's where (ObjectQLStrategy.withReadScope → ObjectQL.aggregate). A scope carrying a shape the shared comparand face refuses, such as a list in an equality slot, comes back as the engine's INVALID_FILTER / 400. Its message names the policy field and quotes the comparand values, for example a resolved membership set. So one scope gets two envelopes across the analytics faces, and the 400 one is the disclosure #5367 closed.

Measured (the #19975 dev, a one-time probe on ae7a35a63b; ⛔ not re-run by this seat)

Direction

The ObjectQL execute face refuses a read scope it cannot run with the same withheld envelope as the other faces (READ_SCOPE_COMPILE_FAILED / 500, fail-closed). ⛔ It does not echo the engine's 400.

  • Where the translation lives is the implementer's measured choice.
  • The first step is to reproduce the probe and measure the HTTP leg.

Governing text: the #5367 ruling (re-affirmed as #7598 Q2 = A), as recorded in read-scope-sql.ts.

Dedupe

One semantic issue search, open and closed, on the query 「analytics objectql strategy read scope INVALID_FILTER 400 error message discloses RLS policy field name and comparand values, withheld 500 on native face」. It returned 42 hits:

Dedupe words: analytics objectql read scope INVALID_FILTER 400 · withReadScope engine.aggregate policy field disclosure · read scope two envelopes native 500 objectql 400 · 5367 withhold objectql strategy

    分诊首次定级:priority:p2 · security · bug · domain:services · pm:blocked —— 分析服务的 ObjectQL 执行面把"跑不了的行级读范围"回成 400,错误信息里带出策略的字段名和比较值;修法的落点正被 #19975 的 PR 修改,排在它后面

    Triage: lands in service-analytics ⇒ domain:services, security, bug, priority:p2, pm:blocked Blocked-by #19975; rationale: the #5367 ruling (re-affirmed by #7598 Q2 = A), recorded in read-scope-sql.ts's header, says a read-scope refusal is a withheld server fault — never a 4xx whose message hands the caller the RLS policy's field names and comparands — and the native / echo faces hold it, but the ObjectQL execute face lets the engine's INVALID_FILTER / 400 through with the policy field and the resolved comparand list in its message; p2 because it discloses policy internals (not rows), reachable today from authored field == current_user.MEMBERSHIP; blocked because the shared read-scope door this face composes through is the file PR #19994 (for #19975, dispatched) is editing, and that PR's own dev surfaced this finding.

    执行要点

    1. read-scope-sql compiles $eq: [...] in a policy scope as col = ? with the array bound (read-scope-sql.ts:1273) — outside ruling 乙's shared face; a bare array fails closed as 500, not 400 #19975 关闭后,在新 main 上先复现 dev 的探针,并补测 HTTP 那一段(经 REST analytics 信封)。
    2. ObjectQL 执行面对"跑不了的读范围"一律回 READ_SCOPE_COMPILE_FAILED / 500、不回显引擎消息,与 native / echo 面一致;落点由实现者按测量选择。
    3. ⚠️ 区分:调用方自己的 where 出错仍应是 INVALID_FILTER / 400(filter-normalizer.ts 那条路);只有读范围那一半要保留信息。测试要同时钉住这两种。

The PR says 'Part of #19995' and the status is needs_decision because seven residue classes, refused by schema/context-reading engine doors and driver-sql, still relay policy content; fixing them soundly belongs to the engine/driver lanes (the refusal reading the #8220 mark) and re-opens the #5367 vs #7929-B envelope choice.

It runs the two faces the engine itself runs on every object-form where (assertListComparandShapes and normalizeFilterComparandTypes from @objectstack/spec/data) on the scope alone. It re-raises any refusal through the module's one envelope helper, readScopeCompileError, keeping the walk's sentence for the operator's log. It is exported from the file only, not from the package entry, so the published surface is unchanged.\n- objectql-strategy.ts: called at both engine-bound merges.\n - withReadScope covers the direct path and the cross-object base aggregate.\n - resolveFkAttr covers the referenced object's own scope.\n - It runs after the vacancy guard and before the 'policy' mark.\n\nWhy at the merge boundary, on the scope alone. At that point the scope is still a distinguishable object. One line later it is $and-composed with the caller's filter, and then nothing downstream can tell whose clause a refusal came from.\n\nWhy the refusal set does not move. The engine's comparand-shape refusal does not read the 'policy' provenance mark (measured below). Both faces are pure walks whose verdict on a subtree depends neither on the rest of the tree nor on any schema. So the scope alone answers exactly as the scope inside { $and: [userFilter, scope] } does, and nothing the engine serves is refused. A { $field } scope (served on this path under #7598 Q1 = B) is stepped around by both faces, as the engine steps around it.\n\n⛔ This is not a catch around executeAggregate. The caller's own where still reaches the engine's doors for some shapes, and those keep their INVALID_FILTER / 400 with the message. This is pinned, and ablation A5 below shows that pin going red under misattribution.\n\n## Measurement: recorded before the fix\n\nMeasured on base 14add487b4, using a scratch probe that is not committed: AnalyticsService (ObjectQL only) over a real ObjectQL, run twice, once over SqlDriver (better-sqlite3) and once over SqliteWasmDriver. The two drivers gave the same answer in every row. The HTTP leg went through the real routes: @objectstack/runtime's dispatcher POST /api/v1/analytics/query and @objectstack/rest's POST /analytics/dataset/query. The read scopes are the getReadScope contract filled by hand. The same probe was re-run after the fix, against a rebuilt dist.\n\n| Read-scope shape class | Layer that answers on the ObjectQL face | Before (ObjectQL face and both HTTP doors) | Refusal text names policy content | After |\n|---|---|---|---|---|\n| List in the implicit equality slot | Engine, shared list-shape face | INVALID_FILTER / 400, relayed | yes | READ_SCOPE_COMPILE_FAILED / 500, withheld |\n| List under $eq | Engine, shared list-shape face | 400, relayed | yes | 500, withheld |\n| Scalar under $in or $nin | Engine, shared list-shape face | 400, relayed | yes | 500, withheld |\n| One-bound $between | Engine, shared list-shape face | 400, relayed | yes | 500, withheld |\n| Null member in $in | Engine, shared list-shape face | 400, relayed | yes | 500, withheld |\n| Plain-object member in $in; plain-object comparand under $eq; undefined comparand | Engine, shared comparand-type face | 400, relayed | yes | 500, withheld |\n| Emptied $nin (control) | Analytics vacancy guard (#13640) | 500, withheld | no (withheld) | unchanged |\n| List under $ne or $gt; nested relation value; cross-field reference | driver-sql, which reads the mark | 400, message withheld | no | unchanged |\n| Column the object does not have | driver-sql, missing column | 400, relayed | yes | unchanged (residue) |\n| Retired or unknown operator | driver-sql operator vocabulary | 400, relayed | yes (the field) | unchanged (residue) |\n| Text operator on a non-text field | Engine, declared-type door | 400, relayed | yes | unchanged (residue) |\n| Temporal comparand the platform cannot read | Engine, temporal door | 400, relayed | yes | unchanged (residue) |\n| Combinator with a non-array operand | driver-sql | 400, relayed | yes | unchanged (residue) |\n| Non-boolean $null or $exists | driver-sql | 400, relayed | yes (the field) | unchanged (residue) |\n| Unknown filter placeholder | Engine token resolver | FILTER_TOKEN_UNKNOWN / 400, relayed | yes | unchanged (residue) |\n| Well-formed scope (control) | — | 200, scoped rows | — | unchanged |\n\n- Hypothesis 2 (does the engine refusal read the mark?): confirmed. The scope reached the engine stamped 'policy' by withReadScope, and the comparand-shape refusal still returned its full text. Of the refusals in the table, only driver-sql's bind and cross-field refusals read the mark.\n- Hypothesis 3 (does the ObjectQL face reach the read-scope compiler?): confirmed. The ObjectQL execute face never reaches compileScopedFilterToSql. The NativeSQL face and the echo answered READ_SCOPE_COMPILE_FAILED / 500 for every fixed class except two: a plain-object comparand under $eq and a null member in $in. That compiler compiles both of those (see Acceptance notes).\n- Scope reads quoted. The strategy has four:\n - generateSql's echo merge compiles through compileScopedFilterToSql, is already withheld, and is untouched.\n - withReadScope and resolveFkAttr are the two engine-bound merges, and both are now guarded.\n - NativeSQLStrategy.applyReadScope compiles and is untouched.\n\n## Tests\n\nThe new file is packages/services/service-analytics/src/__tests__/objectql-read-scope-refusal-envelope.test.ts, with 19 cases over a real ObjectQL and SqliteWasmDriver.\n\n- Refusal cases. Each refused shape class asserts:\n - code READ_SCOPE_COMPILE_FAILED and status 500;\n - that the reads every analytics HTTP door takes before relaying prose (serverFaultProvenance(resolveThrownHttpError(err, 500)) is 'declared', declaredRefusalMessage(err) is undefined) mean the prose is withheld;\n - that the thrown message, which is the operator's log channel, still carries the detail.\n- Paths covered: the direct path, a well-formed caller where beside a refused scope, the cross-object base scope, and the referenced-object scope.\n- Controls:\n - a well-formed scope is served with its rows;\n - a cross-field scope is served;\n - an emptied $in beside an own-rows grant is served;\n - a well-formed referenced-object scope buckets what it hides as (restricted);\n - the caller's own where refused by the ENGINE stays INVALID_FILTER / 400 with its message;\n - the caller's own where in the scope's refused shape stays 400 with its message.\n\nResults:\n\n- Measurement commit e4908254bc (test only, before the fix): Tests 13 failed | 6 passed (19). Every refusal case received INVALID_FILTER, and every control was green.\n- At 9a40317b15:\n - the new file gives Tests 19 passed (19);\n - the whole package gives Test Files 118 passed (118), Tests 2560 passed (2560);\n - pnpm --filter @objectstack/service-analytics typecheck exits 0, and tsc --listFiles includes the new test.\n\nAblations. Each leg ran through scripts/ablation-replace.mjs (the anchor must hit exactly once, and the blob must change) with a trap. Each restore was proven: the blob equals HEAD, and git diff HEAD is empty.\n\n| Leg | Mutation | Result |\n|---|---|---|\n| A1 | Delete the withReadScope call | 12 failed, 7 passed. Every direct and cross-object-base refusal case received INVALID_FILTER. |\n| A2 | Delete the resolveFkAttr call | 1 failed (the referenced-object case), 18 passed |\n| A3 | Delete the comparand-type face call | 3 failed (the three type-face rows) |\n| A4 | Delete the list-shape face call | 10 failed (the shape rows, the composed case, both cross-object cases) |\n| A5 | Judge the COMPOSED tree instead of the scope alone | 1 failed: the caller's engine-refused where received READ_SCOPE_COMPILE_FAILED instead of INVALID_FILTER |\n\n## Gates\n\n- Derived gates. Derived at 9a40317b15 with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands: 72 families, a superset of the dispatch-time list. All 72 exited 0.\n - check:dual-build-cjs-loads and check:type-check-debt first answered PREREQUISITE NOT MET (exit 3). I built the ./packages/* closure and re-ran both, and both exited 0.\n - The --ran reconciliation reported 72 derived, 72 run, 0 unrun.\n- Issue citations. GITHUB_TOKEN=… node scripts/check-issue-citations.mjs exited 0: 10 citations judged, 10 resolve.\n- Lint, narrowed to the four touched TypeScript files. eslint --no-inline-config --format json read 4 files and reported 0 errors and 0 warnings. eslint.config.mjs enables no type-aware linting (no parserOptions.project, no projectService), so this diff cannot move a verdict on an untouched file. pnpm lint itself is CI's.\n\n## Acceptance notes\n\n- @objectstack/objectql is a new devDependency, aliased to source in the package's vitest.config.ts with an anchored regex. This is the repair check:test-source-alias prescribes; the ledger does not grow, and the gate is green. The refusal under test is the engine's own, so a stub bridge would only have tested the stub.\n- Envelope reuse. The guard lives in read-scope-sql.ts because readScopeCompileError is module-local by design. A guard in the strategy file would have needed a second spelling of the envelope.\n- A host with its own executeAggregate bridge: the scope is now judged against the spec's shared comparand faces whichever bridge executes, the same posture as the vacancy guard. A custom bridge that used to tolerate one of these off-contract scope shapes now gets the withheld 500. The engine bridge refused all of them already.\n- Precedence. When the caller's where and the scope are both refused, and only the engine would refuse the caller's clause, the scope's 500 now answers first. A caller clause refused by the analytics where door still answers first, with its 400.\n- NativeSQL face and echo: unchanged. They compile two shapes (a plain-object comparand under $eq, a null member in $in) that the shared faces and the ObjectQL face refuse. This was measured with a stubbed executeRawSql, so the database-level outcome is unmeasured. It is reported to the seat and not touched here.\n- origin/main has moved on by one commit (fc6ddb87a4, driver-sqlite-wasm text round-trip). It shares no path with this diff and is not merged.\n- Files not touched: filter-normalizer.ts, packages/spec, packages/objectql, packages/rest, packages/runtime.\n\n## Residue: why "Part of"\n\nThese classes still answer the engine's or the driver's 400 with the message relayed:\n\n- a column the object does not have;\n- a retired or unknown operator;\n- a text operator on a non-text field;\n- a temporal comparand the platform cannot read;\n- a combinator with a non-array operand;\n- a non-boolean $null or $exists;\n- an unknown filter placeholder.\n\nThey are refused by engine doors that read the object's schema or the request's context, and by driver-sql's own compile. This package cannot judge them without a second copy of those rules. The sound fix is at the refusing layer: the refusal reads the 'policy' provenance mark (#8220), as driver-sql's bind and cross-field refusals already do. That change is in the engine and driver lanes, and it opens an envelope question between the #5367 and #7929 rulings. It is handed back to the seat as a decision.\n"

    Review — ACCEPT, partial (landing gated on CI) · PR #20017 · head 9a40317b15 · domain:services seat · 2026-09-24T19:33Z

    Seat session_01Evb5jFDZGKQE9KG4jbMfMF. Checked against GitHub and origin/main (fc6ddb87a4), ⛔ not against the report's own account.

    Checklist

    • PR shape. Draft, targeting main. The first line is Part of #19995, with no closing keyword (see the answer to open question 2). Clause-②: no starts its own line.
    • Scope. 7 files, +501 / −2:
      • read-scope-sql.ts: the new assertReadScopeComparandsRunnable and a header section;
      • objectql-strategy.ts: two call sites;
      • a new 19-case test file;
      • a devDependency on @objectstack/objectql, with its lockfile link and an anchored source alias in vitest.config.ts;
      • .changeset/19995-objectql-read-scope-envelope.md (@objectstack/service-analytics patch).
        No packages/spec, no packages/objectql source, no filter-normalizer.ts. No cycle: objectql does not depend on service-analytics.
    • Diff, read line by line.
      • The guard runs the engine's two shared comparand faces on the scope alone, at both engine-bound merges (withReadScope, resolveFkAttr). It runs after the vacancy guard and before the 'policy' mark. Any throw is re-raised through the module's one envelope helper, readScopeCompileError.
      • The type face is copy-on-write, so its discarded return leaves the scope object untouched: the host's scope is not mutated.
      • It is not a catch around executeAggregate, so the caller's where keeps its 400.
    • Tests. The measurement commit ran 13 red / 6 green before the fix. The new file is 19/19 green; the package is 2560 green.
      • Ablations A1–A5 each go red, including A5 (judging the composed tree misattributes the caller's refusal), and every restore is blob-identical.
      • The HTTP leg was measured on both doors and both drivers: the nine fixed classes go from 400 carrying policy content to 500 carrying none. Caller-where rows are identical before and after.
    • Changeset prose. I read it against the diff; every claim matches, including 「Unchanged: which scopes are served」 (same functions as the engine).

    Open questions, answered:

    1. The residue (seven scope shape classes still answer a relayed 400 carrying policy content): to the maintainer. It cannot be fixed in this lane: the refusals are the engine's schema- and context-reading doors and driver-sql's own compile. Choosing the envelope re-opens the standing rulings analytics dataset 路由的 message 正则兜底没有退休时间表:六族拒收仍靠措辞分类,改一个字就换一个 HTTP 码 #5367 (read scope = withheld 500) and finding: after the #7598 Q1=B ruling, a read scope with a driver-refused field reference answers 400 from the driver — which cuts across #5367's attribution argument on that one path #7929 B (a policy-marked refusal = withheld 400). This card moves to the decision box once PR fix(service-analytics): the ObjectQL execute face refuses an unrunnable read scope in the withheld READ_SCOPE_COMPILE_FAILED / 500 envelope #20017 lands, with the four-axis analysis. ⛔ Not decided by this seat.
    2. "Part of" and the test assertions: A (accepted). A merge must not close a card headed to the decision box. The thrown message keeps its detail for the operator's log, as the module's analytics dataset 路由的 message 正则兜底没有退休时间表:六族拒收仍靠措辞分类,改一个字就换一个 HTTP 码 #5367 design says (pinned by read-scope-refusal-envelope.test.ts). What is withheld is the HTTP body, measured on both doors.

    Deviations accepted. The devDependency, lockfile and alias (the repair check:test-source-alias prescribes); the test driver SqliteWasmDriver (a SqlDriver subclass; better-sqlite3 was measured identical in the probe). The claim's file surface is revised to include package.json, vitest.config.ts and pnpm-lock.yaml (this line is the revision).

    Out-of-scope findings, one line each: the NativeSQL read-scope compiler and the echo compile two scope shapes the shared faces refuse (a plain-object comparand under $eq, a null member in $in), so those two shapes still get two answers across the faces: filed next, class b.

    Landing. No Clause-② limb is hit: no packages/spec/src, and the declaration is no (the envelope of an already-refused scope moves; no scope that was served is refused). The seat's review covers the changeset prose, per the maintainer's 2026-09-10 tier ruling. The PR waits on every check going green, then goes ready and auto-merge.

    Correction to the seat's ACCEPT above, on open question 1 (the residue). domain:services seat (session_01Evb5jFDZGKQE9KG4jbMfMF) · 2026-09-24T19:37Z

    The ACCEPT sent the residue to the maintainer. That was wrong: a standing ruling already answers it, so it is execution, ⛔ not a decision.
