metadata read: for a platform-admin caller the object read and the sortability projection keep a field that caller's field-level permission marks unreadable, while the data route refuses it

[objectstack-fleet]

Filing gate ①: a measured inconsistency, class (b): two server answers disagree for one caller. It is not a value leak. Measured by an objectui dev on objectstack-ai/objectui#11925 against a booted, published @objectstack/* 17.7.0 server, over REST. Kept abstract, per the triage posture on that card: classes, positions and functions only.

Who acts on it: objectstack triage, grade and route (the metadata read and the security service). ⛔ Not a claim. Filed by the objectui domain:ui execution seat 1 (session_01DrKzdPdyLLBW3qpZ4vtk7z).

What happens

For a platform-admin caller whose field-level permission marks one field of an object unreadable (through a permission set bound to everyone):

• The permission read (/auth/me/permissions) answers that field as readable: false.
• The data read leaves the field out of rows, and a filter or sort on it is refused with 403 by the filter-oracle guard. That is right, and it is why no value leaks.
• The object metadata read (/meta/object/<name>) still lists the field in fields, and the sortability projection marks it sortable: true.

For a non-admin caller with the same permission set, the metadata read hides the field, as #3661's masking intends. So the masking is skipped for the platform-admin class while that caller's own field permission and data route deny the field.

Consequence

A client that builds pickers from the metadata read offers the field to that caller, and choosing it hits the 403. objectui#11925 (Filter panel) and a sibling objectui card (Sort picker) close it client-side with the permission read. The server's metadata, sortability and data answers should still agree for one caller.

Done when

• For a caller whose field permission marks a field unreadable, the metadata read and the sortability projection agree with the data route: the field is masked from fields and not offered as sortable, whatever the caller's class. Alternatively, if a platform admin is meant to see such definitions, the permission read and data route say so too and the 403 does not fire.
• Pinned per caller class.

Duplicate check

• Semantic issue search on objectstack-ai/objectstack, object metadata read field-level mask platform admin unreadable field sortability sortable: 4 hits, none the same. 元数据面未做字段级权限掩码：/meta 返回完整 fields，导入模板列不受 FLS 约束，客户端 field.permissions 守卫是死代码 #3661 (closed) introduced the masking, and Declare metadata.maskObjectFields on MetadataEndpointsConfigSchema and getMetadataReadableFields on ISecurityService (ADR-0106 follow-through) #6622 and finding(spec): the protocol declares no masked field-type set — objectql's collectMaskedReadFields and objectui's MASKED_FIELD_TYPES each own a copy of one fact #20141 are its follow-ups. None names the platform-admin class or sortability.

Dedupe words: meta object FLS mask platform admin · sortability unreadable field sortable true · metadata field level security admin bypass

Triage: first grade, bug · priority:p3 · domain:engine · area:access · pm:queue. Direction: make the server's answers agree by tightening; ⛔ never by loosening the data route

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-08T09:59Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in the metadata read's field masking (#3661's path) and the sortability projection ⇒ domain:engine; rationale: the metadata read is that lane's. If the bypass lives in the security service, the seat names it and the domain:services seat reviews.

• Why p3: no value leaks. The data route's guard holds, and the client half closes on objectui#11925 and objectui#11943.
• Measure first why the masking skips the platform-admin class. Find the exemption and its stated reason.
  • If it exists so authoring surfaces (Studio, Setup) see full definitions, keep the definition read for authoring. Make the runtime projections (sortability, and any picker-facing field list) agree with the caller's field permission.
  • If it has no reason, mask for every class.
• ⛔ The card's other alternative, making the permission read and the data route admit, loosens a field-level boundary. That is the maintainer's, not this lane's or triage's.
• Pins: per caller class, as the card says. Control: a non-admin is unchanged.

  File surface (at origin/main 8cbe255ef6+), per triage 6057391955:
• Measure first: why the object-schema field mask (元数据面未做字段级权限掩码：/meta 返回完整 fields，导入模板列不受 FLS 约束，客户端 field.permissions 守卫是死代码 #3661's path) skips the platform-admin class: find the exemption and its stated reason. Likely metadata-core's object-schema-fls.ts (the caller-class exemption near its getReadableFields bypass note) and its callers in runtime's domains/meta.ts (maskObjectSchema) and rest's meta-item-read-gate.ts.
• Direction (triage): tighten, never loosen. If the exemption exists so authoring surfaces see full definitions, keep the authoring definition read and make the runtime projections (sortability, any picker-facing field list) agree with the caller's field permission. If it has no reason, mask for every class. ⛔ Making the permission read and the data route admit the field is the maintainer's, not this lane's.
• Pins per caller class (platform admin, organization admin, member); control: a non-admin caller is unchanged.
• .changeset/22250-*.md (graded minor for metadata-core and rest by the widening, patch for runtime).
• Added (patch round 1), cross-lane domain:spec, declared on [PM seat] domain:spec — 🟢 os-litant · session_01LAi5BVvQNiYzepSAcsoFLK #6017: packages/spec/src/api/sortability.zod.ts, the ObjectSortabilitySchema.fields description and the module docblock's absence list (a field the caller's field permission withholds, served in item.fields to a D4-exempt caller, has no entry), plus the generated outputs its regen rewrites. Text only; no schema shape change.
  Container & model: M, mode:subagent, model: default (dispatch-gates --tier: no path-derived mandate).
  Clause-②: yes
• Revised from no on the dev's measurement of the built entry declarations (report 6061977564), which decides it (execution-duties: the seat does not build). @objectstack/metadata-core exports resolveObjectSchemaRuntimeView, ObjectSchemaRuntimeView and ObjectSchemaRuntimeFieldPosture, and ObjectSchemaMaskPosture's passthrough member gains an optional runtime. @objectstack/rest's translateMetaEnvelope and MetaItemAnswerSources.translateEnvelope each gain an optional parameter. Nothing is narrowed in a declaration.
• Behaviour: the sortability projection narrows for one caller class (a D4-exempt caller no longer gets an entry for a field its own field permission withholds), to agree with that caller's field permission and the data route. item.fields is unchanged for every class.
• A contract-tier review on the final head is owed before the queue.
  Responsibility: the object-schema mask's caller-class exemption produces the disagreement | the data route's guard already refuses the field, so no value leaks | a platform-admin client building pickers from the metadata read reaches it today (measured on objectui#11925)

Its stated reason is 'Studio/Setup authoring requires the full schema', and the code adds that a projected read PUT back deletes the withheld fields. That is the ruling's first branch: the authoring definition read is kept. M2 was partly falsified: the sortability projection (rest translateMetaEnvelope, used by both transports) already read the post-mask document, but for an exempt caller that document is unmasked, so it inherited the exemption. Fix: the exempt posture of a capability-exempt caller carries a lazy runtime question that asks the same getMetadataReadableFields the mask asks a non-exempt caller. It is asked at most once and never rejects; a throw or undefined answer settles undetermined with one warn, so D4's sick-service invariant holds. resolveObjectSchemaRuntimeView derives the view sortability is computed from, on both item-read transports and the cached arm. The cached arm folds a qualified fingerprint of the withheld fields into the ETag and judges the conditional itself. Result on a real app-showcase boot: platform admin and organization admin keep the full item.fields, and sortability no longer names the unreadable field (byte-equal to the member's). Member unchanged. Permission read and data route unchanged. Unrestricted admin ETag byte-identical. sortability is the only server-side picker-facing projection beside the definition; item.fields IS the authoring definition the ruling keeps, and objectui handles its pickers against the permission read (objectui#11925 / objectui#11943).",

"body": "Fixes #22250\nClause-②: yes (widening)\n\n## What this does\n\nFor one caller, the object metadata read and the data route disagreed about a field that caller's field-level permission marks unreadable. The sortability projection served beside the schema on GET /meta/object/NAME marked that field sortable: true for a platform-admin or organization-admin caller, while the data route refuses a sort or filter on it with 403 PERMISSION_DENIED.\n\nAfter this PR, the sortability projection is derived from the caller's own field permission for every caller class. The object definition itself (item.fields) is unchanged: whole for the exempt classes, because Studio and Setup authoring need it, and masked for everyone else. The data route and the permission read are unchanged. The spec's description of the projection is amended to match.\n\n## Measured first: the exemption and its stated reason\n\n- Where it is. isObjectSchemaMaskExempt in packages/metadata-core/src/object-schema-fls.ts (ADR-0106 D4). It exempts isSystem and any caller holding manage_metadata, studio.access or setup.access. The platform-admin set holds all three. An organization admin holds setup.access. resolveObjectSchemaMaskPosture answers such a caller passthrough / exempt before it asks the security service.\n- Its stated reason. ADR-0106 D4: "Studio/Setup authoring requires the full schema." The code adds the write-gate derivation: a projected read sent back by a PUT would delete the fields it withheld. So this is the triage ruling's first branch: keep the definition read for authoring, and make the runtime projections agree with the caller's field permission.\n- Dispatch assumption M2 was partly wrong. The sortability projection (translateMetaEnvelope in packages/rest/src/meta-item-read-gate.ts, which both transports call) already read the post-mask document. For an exempt caller, though, that document is the unmasked one, so the projection inherited the exemption.\n- Picker-facing field lists on the server. sortability is the only runtime projection the object read serves beside the definition. The list read and the layered view serve definitions only, with no projection. item.fields is itself the definition the ruling keeps for authoring. objectui handles its pickers against the permission read on its side (objectui#11925, objectui#11943).\n\n## Door table: examples/app-showcase, real boot\n\nSetup: showcase_client_liaison (which marks showcase_project.budget, spent and budget_remaining as readable: false) is bound to the everyone position. Callers: the seeded platform admin; phone.demo promoted to organization admin; auditor.demo as a member.\n\nThe table was measured at base c8bb3c8d9c and at head 8b412a83e2, then re-measured on the final head a337d0cc53, which carries 805f1ba09a's change to the exemption predicate's source and the spec text. Every head cell below reads the same on 8b412a83e2 and on a337d0cc53.\n\n| Door | Platform admin, base → head | Organization admin, base → head | Member (control), base → head |\n|---|---|---|---|\n| GET /auth/me/permissions, budget | readable: false → same | readable: false → same | readable: false → same |\n| GET /data/showcase_project | field absent from rows → same | field absent → same | field absent → same |\n| GET /data/showcase_project?sort=budget (and ?budget=100) | 403 PERMISSION_DENIED → same | 403 → same | 403 → same |\n| GET /meta/object/showcase_project, item.fields.budget | present (22 fields) → present (22) | present (22) → present (22) | absent (19) → absent (19) |\n| same read, sortability.fields.budget | { sortable: true } (23 entries) → absent (20 entries) | { sortable: true } (23) → absent (20) | absent (20) → absent (20) |\n| same read, ETag | \"39ce56dc\" → \"39ce56dc~3c4b8092\" | \"39ce56dc\" → \"39ce56dc~3c4b8092\" | \"39ce56dc~32c59ec2\" → same |\n| GET /meta/object/showcase_project/layers (authoring) | effective 22 fields with budget → same | same → same | 19 without budget → same |\n\nAt head, all three classes are served byte-equal sortability. Conditional reads, the same on both heads:\n- The platform admin's own ETag answers 304, and so does the organization admin's own ETag (on a337d0cc53).\n- The pre-change ETag \"39ce56dc\" answers 200.\n- The member sending the admin's ETag gets 200.\n\nAfter unbinding the set, the unrestricted admin's ETag is \"39ce56dc\" again (byte-identical, ADR-0106 D3), and budget is { sortable: true } with 23 entries.\n\n## How\n\n- @objectstack/metadata-core (object-schema-fls.ts). The exempt posture of a caller exempt by capability, in a deployment with a security service, carries a lazy runtime question. That question asks the same getMetadataReadableFields the mask asks a non-exempt caller, at most once. It never rejects: a throw or an undefined answer settles undetermined, with one warn, so D4's "a sick security service cannot fault an exempt caller" holds. resolveObjectSchemaRuntimeView(document, posture) returns the view the runtime projections are derived from: the served document for every other caller, and for an exempt caller the fields their permission reads, plus a fingerprint of what it withholds. Each withheld name in that fingerprint carries a qualifier (@ occurs in no machine name), so an exempt caller and a projected caller denied the same field never share a validator. isObjectSchemaMaskExempt now delegates its capability half to a private helper, which the resolver asks alone. That adds no second elevation read (check:system-context-census).\n- @objectstack/rest.\n - translateMetaEnvelope takes an optional runtimeDocument (default: the served document) and derives sortability from it.\n - createMetaItemAnswer step 5 computes the runtime view and passes it through the translateEnvelope port, which gains an optional third parameter.\n - In rest-server.ts, the cached arm of GET /meta/:type/:name treats a posture carrying runtime like a projecting posture: the protocol is not handed If-None-Match, the runtime view's fingerprint is folded into the ETag, and the 304 is judged against that folded value. The private translateMetaEnvelope and metaItemAnswerSources forward the view.\n- @objectstack/runtime (domains/meta.ts). Only answerMetaItem's translateEnvelope port, which forwards runtimeDocument. Every dispatcher item read already goes through createMetaItemAnswer.\n\n## Spec text (cross-lane, domain:spec)\n\nDeclared by the seat on domain:spec's seat post. The change is to text only: no shape, key, enum or accept-set change.\n- packages/spec/src/api/sortability.zod.ts.\n - The ObjectSortabilitySchema.fields .describe() now says: "The domain is the served field map plus the always-provisioned id, less any field the caller's own field permission withholds: a caller exempt from the object-schema mask (ADR-0106 D4) is served such fields in item and gets no entry for them; for every other caller the served map already excludes them." The list of absent names gains "a field the caller may not read".\n - The module docblock's category list gains case 5, "Withheld by the caller's field permission". Case 1's domain sentence carries the same exception, which removes nothing for every caller but a D4-exempt one.\n - resolveObjectSortability's docblock says that, for a D4-exempt caller, it runs on the document narrowed to the fields the caller's own permission reads.\n- Generated. content/docs/references/api/sortability.mdx and content/docs/references/api/protocol.mdx were regenerated by pnpm --filter @objectstack/spec check:generated --fix. That forced a spec build, found only check:docs stale (14 of 15 green), and regenerated it. A second check:generated run then reported all 15 artifacts current. Nothing generated was hand-edited.\n- Changeset. No @objectstack/spec entry was added, because no changeset gate requires one for a description-only change:\n - Check Changeset (pr-automation.yml) counts the changesets a PR adds;\n - check-changeset-no-major.mjs, driven offline with this body as its event, reads Clause-②: yes (widening) and is satisfied by metadata-core and rest graded minor, and it lists no ungraded spec package;\n - check-empty-changeset.mjs is green.\n\n## Tests\n\n- packages/metadata-core/src/object-schema-fls.test.ts (new describe block):\n - per class (platform admin, organization admin, member): the runtime view holds only the readable fields, the exempt definition is served whole, and the member's view is the served document by reference;\n - one permission gives one view whatever the class; no validator is shared with the definition mask;\n - an unrestricted exempt caller is byte-identical; the question is lazy and asked at most once, and never for a document without fields;\n - undefined and a throw both settle undetermined with a warn; isSystem and a deployment with no service carry no question.\n\n One existing assertion went from toEqual to toMatchObject plus a typeof runtime === 'function' check, because the exempt posture now carries the function. Its "asks nothing" pin (asked === 0) is kept.\n- packages/rest/src/meta-object-sortability-caller-fls.test.ts (new), per class, on the cached (default) and uncached branches:\n - the definition is unchanged, sortability never names the unreadable field, and it is equal across classes;\n - the member control still agrees with resolveObjectSortability(item);\n - the cached arm's ETag is fingerprinted, the protocol is not handed the conditional, the admin's own ETag answers 304, the member's ETag does not cross over, and an unrestricted admin keeps \"v1\" and its 304;\n - a throwing service answers 200 with the definition and the unprojected sortability.\n- packages/runtime/src/domains/meta-object-sortability-caller-fls.test.ts (new): the same per-class pins on the dispatcher's protocol-backed and registry-backed item reads.\n\nReverse verification (from committed state, on-disk proof by scripts/ablation-replace.mjs):\n- A. translateMetaEnvelope was mutated to derive sortability from the served document (the behaviour before this PR). The REST suite went 5 failed / 8 passed. After pnpm --filter @objectstack/rest build, ablation-dist-preflight found the marker in dist, and the runtime suite went 4 failed / 4 passed. Restore: blob equal to HEAD, git diff HEAD empty; rebuild; preflight --absent with a clean tree; 13/13 and 8/8 green.\n- B. The exempt posture was mutated to never carry runtime. The metadata-core file went 7 failed / 29 passed, all assertion failures. Restored, blob equal to HEAD.\n\nThe first B attempt used an undefined identifier and went red on a ReferenceError, so that reading is void. The second was refused by the tool because the replacement contained the anchor, so nothing was mutated.\n\n## Local verification (final head a337d0cc53)\n\nAll suites ran through the shared verify lock. Exit codes were read from its VERDICT line.\n\n- This round (spec text and regenerated docs).\n - @objectstack/spec test: 625 files, 18711 passed and 1 todo. typecheck exit 0, which includes check:scripts-typecheck and check:test-typecheck.\n - dispatch-gates --commands derives 111 commands for the full touched path set (11 paths). All 111 ran and exited 0.\n - --ran reconciliation: 111 derived, 111 run, 0 NOT-MEASURED, 0 UNRUN (a derived zero: every entry records its exit code).\n - The derivation warns that one file it reads, scripts/platform-object-tenancy-census.json, changed on main since this branch's merge base, so that family read this branch's copy.\n - Narrowed lint on sortability.zod.ts:\n - eslint --no-inline-config --format json reports 1 file, 0 errors and 0 warnings.\n - The effective config (--print-config) enables 5 syntax rules and parserOptions.project is null.\n - With no type-aware linting, the change cannot move a verdict on a file it does not touch.\n- Earlier round (unchanged since).\n - @objectstack/metadata-core: 18 files, 425 passed; typecheck exit 0.\n - @objectstack/rest at 3768ffad20: 268 files, 5142 passed and 327 skipped; typecheck exit 0.\n - @objectstack/runtime: 340 files, 5508 passed and 19 skipped at 805f1ba09a; typecheck exit 0 at 3768ffad20.\n - Narrowed lint over those 7 files: 0 errors and 0 warnings.\n - Gates: 64 of 64 exited 0 at 3768ffad20.\n- Merge. main was merged once, at 9865012548 (#22265 touched rest-server.ts and runtime/src/domains/meta.ts in a different region). Against the current origin/main, git merge-tree --write-tree exits 0 and no file overlaps, so no second merge was made.\n\n## Answered by the seat\n\n- Clause-②. The measurement decides: yes (widening), with minor for metadata-core and rest and patch for runtime. The claim's line was revised to match. Two transport-local copies of the posture logic were refused.\n- The spec text. It rides this PR, not a separate card, with packages/spec lifted for exactly this text. It is declared cross-lane on domain:spec's seat post.\n\n## Acceptance notes\n\nThese are observations only, read from source and not measured. No card is filed for them.\n- objectui's docblock. objectui's packages/core/src/utils/column-sortability.ts repeats the sentence this PR amends ("the served field map plus the always-provisioned id"). That is another repo and is not edited here. Carrier: objectui domain:ui seat 1 (objectui#11925's filer).\n- Partially masked fields. For any caller, sortability keys on readability, while the security service's query guard also refuses a predicate or sort on a field served partially masked (maskingRule). Per getQueryableFields's docblock, a masked field is readable but not queryable. No in-repo app declares a maskingRule today (showcase permission-sets.ts). Whoever touches resolveObjectSortability next should weigh it.\n- External objects. On an ADR-0015 external object, an author-declared platform-injected column that the caller cannot read is re-added by unprovisionedInjectedColumns as sortable: true plus a caveat once the mask removes the declaration. This is the same for every class.\n\n---\n\n_Generated by Claude Code_\n"

ACCEPT (seat review) — PR #22308 at head a337d0cc53

domain:engine#1 · session_01EUBvqtauTDmHi2ZgY759p2 (os-litant) · read at 2026-10-08T15:54Z. The dev's reports are os-dev-report 6061977564 (build) and 6063483631 (patch round 1). Contract review at CONTRACT_REVIEW_TIER: PASS 6063770280 on this head. That is the review the narrowing owes, and the yes owes it too.

• Shape: draft, base main. Line 1 is Fixes #22250, line 2 Clause-②: yes (widening). One closing keyword. The seat wrote the body from round 1's pr_body_full.
• Root cause, measured first: ADR-0106 D4's exemption (isObjectSchemaMaskExempt: isSystem, manage_metadata, studio.access, setup.access) keeps the authoring definition whole, for the reason D4 states. The sortability projection inherited it because it read the served (unmasked) document.
• The fix, triage's first branch:
  • For a capability-exempt caller, the exempt posture carries a lazy runtime question that asks the same getMetadataReadableFields the mask asks. resolveObjectSchemaRuntimeView feeds sortability on both transports and the cached arm.
  • item.fields is unchanged for every class. The permission read and the data route are untouched.
  • D4's sick-service invariant holds: the question never rejects, and a failure settles undetermined with one warn.
  • D3 holds: an unrestricted exempt caller's ETag is byte-identical.
• Door table: a real app-showcase boot, measured on the final head a337d0cc53 and identical to 8b412a83e2.
  • For the platform admin and the organization admin, sortability.fields.budget goes from { sortable: true } to absent.
  • item.fields.budget stays present for those two.
  • The member is unchanged.
  • The 304/200 conditional rows behave as pinned.
• Clause-② revised to yes on the dev's measurement of the built entry declarations: metadata-core gains resolveObjectSchemaRuntimeView, ObjectSchemaRuntimeView, ObjectSchemaRuntimeFieldPosture and an optional runtime; rest gains two optional parameters. The claim's line was edited to match (6058980283). Changeset: metadata-core minor, rest minor, runtime patch, in pre mode. The review agrees.
• Spec text (cross-lane domain:spec, declared on [PM seat] domain:spec — 🟢 os-litant · session_01LAi5BVvQNiYzepSAcsoFLK #6017 as 6062064959): text only, in sortability.zod.ts. The ObjectSortabilitySchema.fields description, docblock case 5, the case 1 sentence, and resolveObjectSortability's docblock now say the domain excludes a field the caller's own permission withholds. The two reference pages were regenerated by check:generated --fix. No objection came on metadata read: for a platform-admin caller the object read and the sortability projection keep a field that caller's field-level permission marks unreadable, while the data route refuses it #22250.
• Noted, not reworked: the changeset names no spec file, so the release notes will not mention the description amendment. The review judged that a missing sentence, not a wrong one, and not a FAIL condition.
• CI on a337d0cc53, by name: all success: Lint & Repo Gates, TypeScript Type Check, Test Core, Dogfood Regression Gate, Build Core, Temporal Conformance and Governed Surface Queue Guard. check-expected-skips is OK (4 skips, all in the roster). The PR is NOT governed (813 changed lines), and git merge-tree against origin/main is clean.
• Out of scope, one line each (Acceptance notes, read from source, not measured):
  • objectui's column-sortability.ts docblock repeats the old sentence. Carrier: objectui domain:ui seat 1.
  • A maskingRule field is readable but not queryable, yet listed sortable for every class. Carrier: the next PR that touches resolveObjectSortability.
  • An ADR-0015 external object's masked injected column is re-added by unprovisionedInjectedColumns. No carrier.
• Next: ready, then auto-merge after the ready-flip checks settle.
