security(forms): two public-form doors meet a field masking rule wrongly — the submit read-back serves masked fields stored to an anonymous submitter, and a picker whose first display field is masked answers 403 to every caller it applies to

Filing gate: ① a product defect with a measured reach:, two positions of one family: public-form doors and maskingRule. ⚠️ Disclosure discipline: doors, caller classes, codes and statuses only. Every reading is private.

reach: public form doors on a real boot, measured by #20995's dev (os-dev-report 5924254306 on #20995, out_of_scope_findings F2 and F4). The readings are in that dev's private scratch space; this seat has read them. Filed by the domain:services execution seat (#6021, session_01XY5uCwTjZj7884yYtyur4H). ⛔ Not a claim.

Position 1: the public-form submit read-back (F2)

The caller class: an anonymous submitter through a form's public grant. The grant hands the operation through before any permission set is resolved, so the zero-set fix of security(plugin-security): for a caller who resolves no permission set, the field-projection answers say no masking rule reaches it, while maskingRule's describe and the result masker mask it — which one a public door serves is not measured #20995 (PR fix(plugin-security)!: a caller who resolves no permission set is served a masked field masked and may not query on it #21051) does not reach it.
What is served: the record echoed after submit carries fields whose masking rule applies, as stored:
- the submitted masked field;
- a masked field filled from its defaultValue that is not on the form.
The contract it disagrees with: maskingRule's describe ("Masked for every non-system caller unless …").
Measured before and after PR fix(plugin-security)!: a caller who resolves no permission set is served a masked field masked and may not query on it #21051. Unchanged by it: it is a different mechanism.

Position 2: a public picker whose FIRST display field declares a masking rule (F4)

After PR fix(plugin-security)!: a caller who resolves no permission set is served a masked field masked and may not query on it #21051 (the safe side for security(plugin-security): for a caller who resolves no permission set, the field-projection answers say no masking rule reaches it, while maskingRule's describe and the result masker mask it — which one a public door serves is not measured #20995's caller class), a form's public lookup picker answers 403 PERMISSION_DENIED to every caller the rule applies to. It does so when the FIRST of its display fields declares a masking rule, because the door sorts and searches by that field, and a query naming a masked field is refused.
Authoring accepts the shape, so an AI or an author can write a picker the runtime refuses for its whole audience.
PR fix(plugin-security)!: a caller who resolves no permission set is served a masked field masked and may not query on it #21051's contract review (5924418816) judged the 403 the right safe side. It found that its changeset covers the consequence by class and mechanism, but names neither this door nor its remedy.

Scope for whoever takes it (⛔ not a ruling)

Position 1: the submit read-back serves the masking rule's answer to the submitter, through the same mask the result masker applies. ⛔ No second derivation of masking. Whether the echo should carry masked fields at all is part of the measurement.
Position 2:
- an authoring-time refusal (or warning) for a picker whose sort/search field is masked; or
- the door sorts and searches by the first display field that is NOT masked;
- and the changeset or doc names the remedy.
  Which one is triage's / the owner's call. A spec or lint leg would be domain:spec.
Pins: each position by class through its public door, with a non-masked control.

Reader who acts

Triage (grade and route; the form doors' files, and an authoring leg if chosen), then the owning seat.

Dedupe

mcp__github__search_issues, repo-scoped, open and closed, in the act that filed this card:

「public form submit read-back masked field picker displayFields maskingRule」: 2 hits, both closed. spec/security: field masking is all-or-nothing — no partial masking (phone last-4, ID middle-8), and maskingRule was pruned as dead in 2026-06 #8993 (partial masking introduced) and security explain: the field-mask layer does not report partial masking (maskingRule) — gated fields read as fully hidden, gate-less rule fields as fully readable #9127 (explain does not report partial masking) are other positions.
The neighbours are security(plugin-security): for a caller who resolves no permission set, the field-projection answers say no masking rule reaches it, while maskingRule's describe and the result masker mask it — which one a public door serves is not measured #20995 (this caller-class family's masking, PR fix(plugin-security)!: a caller who resolves no permission set is served a masked field masked and may not query on it #21051) and security (P0 suspect): a non-system caller who resolves no permission set — an unauthenticated one included — is admitted to aggregate any object at an analytics door, object admission and row scope skipped #21061 (the same caller class's object admission).

Dedupe words: public form grant read-back masking · publicFormGrant step 4 · publicPicker displayFields masked first field · picker sort masked

Premise held on real boots at base dff98c1: on both deployment shapes (no guest set, the showcase's shape; a guest set the route's grant context names), the anonymous submit door's 201 echo carried a masked field the form collects and a masked field filled from its default (not on the form) as STORED; readings are private (scratch issue-21062/readings.txt). H2: on that door the grant's context reaches the engine with the insert alone, so the read-back IS the insert result; step 4 (the result masker) is the one skipped step that bears on this card. H3: the route's grant context resolves no set without a guest set (so the zero-set stand-in) and exactly the guest set with one. H4 as built: step 4's body moves byte-identically into the private maskOperationResult, which step 4 and the publicFormGrant branch both call (one masker, no copy). The grant branch resolves its caller as the data plane does (resolvePermissionSetsForContext, then resolveCallerPosture, which is called, not edited) before next(), fails closed on either input (403 PERMISSION_DENIED, nothing written), and masks the result after next(). A grant context is never the principal-less hand-off. Admission is unchanged (declared object; insert, find, findOne, count; the server-managed strip untouched). After the fix both masked classes are echoed masked on both deployments, and the control field is stored. Surface amendment, declared: the step-4 move sits outside the grant region in the same file, because the masker cannot be reached from the grant branch otherwise without a copy; the zero-set stand-in, packages/rest/src and packages/spec/src are not edited. Deviations: (1) no empty-branch push before the first edit, because the order's push-only-after-the-fix rule is stricter; the first push carried pins plus fix after the ablation; (2) the fail-closed refusals are new answers on failure paths only (the posture one is not reachable on the submit door in a healthy composition), pinned and stated in the changeset; (3) origin/main was merged once before the gate run (7 commits, none in plugin-security); it then moved 8 more, none touching this diff, and was not merged again; (4) the single locked gate run held the lock 24m53s (a full build was 510s of it), and the lock tool flagged the long hold.

The dev report is 5926107785. This seat read it and the PR body on GitHub, disclosure first. Both name doors, caller classes, functions, files and statuses only. There is no field spelling, form slug, request body or returned value, and the readings are private.

Checklist, read on GitHub rather than from the report:

Shape: a draft onto main, 4 files, +537 / −25: security-plugin.ts, a plugin pin, a dogfood pin and the changeset. Line 1 is Part of #21062, and line 2 is Clause-②: no (narrowing). Assigned os-justin.
Triage's direction, as built (5925021024, position 1): the publicFormGrant branch keeps its admission exactly. That is the declared object; insert / find / findOne / count; the server-managed strip unchanged. The result now passes the same masker the data plane uses, for the caller the grant stands in for.
- That caller is resolved as the data plane resolves it (resolvePermissionSetsForContext, then resolveCallerPosture, which is called, not edited).
- On a deployment with no guest set, that is the zero-set stand-in PR fix(plugin-security)!: a caller who resolves no permission set is served a masked field masked and may not query on it #21051 landed; with a guest set, it is that set.
One masker: step 4's body moves byte-identically into a private maskOperationResult. Step 4 and the grant branch both call it, so there is no copy.
Measured (real boots, both deployment shapes, private): the anonymous submit door's 201 echo served the masked field the form collects, and the masked field filled from its default, as stored. After the fix, both are served masked on both shapes, and the control field is stored.
Pins and ablation:
- red first: unit 7 red / 8 green, and dogfood 2 / 2 red;
- green: 15 / 15 and 2 / 2;
- ablation (the grant branch returns before the masker again, dist proven rebuilt) turned exactly the predicted five unit pins and both dogfood pins. The restore was proven.
Gates: 67 derived, 67 run, exit 0, at the merged head.
CI at this reading: 13 success, 3 skipped, 16 in progress, 0 failure.

Decisions:

Surface, accepted as a declared amendment. The step-4 extraction (≈:3834) and the new private method (≈:9001) sit outside the claimed grant-branch region, in the same file. They are the only way to reach the one masker without a copy.
- The zero-set stand-in (≈:2238, ≈:5633), which security(spec): a capability-gated field (requiredPermissions, no maskingRule) is served stored to a caller who resolves no permission set, while explain reports it hidden; narrowing it moves getReadableFields' contract answer #21063 holds, is untouched.
- This seat adds the two regions to its declaration on domain:spec seat 2's post ([PM seat] domain:spec · seat 2 — 🟢 sunhaolin #18549) in this act.
The fail-closed refusals, accepted. If the grant's caller cannot be resolved (sets or posture), the submit is refused 403 before anything is written. These are new answers on failure paths only, pinned, and stated in the changeset. A grant that bypasses an unresolvable masker would be the bypass this card removes.
Clause-②: no (narrowing), accepted. The changeset is minor with the BREAKING banner and ADR-0087 not-required (no-migration-prescription). The at-tier review judges the note.

Findings, line by line:

Under the grant, step 2.9 (the predicate guard) does not run, so a grant find / findOne / count with a predicate on a masked field is admitted. This was measured at the engine only. No public door issues those operations under the grant: the submit door issues the insert alone. Acceptance notes: there is no public-door reach, so by the filing gate it is not a card. This seat names it so a future door that reads under the grant meets it.
Under the grant, step 2.5a (the masked-echo write refusal) does not run, so an anonymous create can store a mask-shaped value. That is value integrity, not exposure, and it is unchanged here: Acceptance notes.
A capability-gated field with no masking rule is still echoed stored on a deployment with no guest set, because the zero-set stand-in has no capability fold. Carried by security(spec): a capability-gated field (requiredPermissions, no maskingRule) is served stored to a caller who resolves no permission set, while explain reports it hidden; narrowing it moves getReadableFields' contract answer #21063 (domain:spec seat 2). Since the echo now reads through the one masker, that fix reaches this door with no further change.

Landing waits for every check green on the head and the at-tier contract review. The card stays open for position 2 (PR from claude/issue-21062-picker-queryable-key, building).

PR #21101 merged through the merge queue as 9c8b65aa on origin/main. It carries Part of #21062, so this card stays open for position 2.

Review: the at-tier contract review PASS on the landed head d076cc60 is 5926306898.
Content check: the landed commit is a single-parent squash. Its git patch-id --stable equals that of the reviewed head d076cc60 against its base 63d1a7c3.

What now holds (plugin-security): the record an anonymous public-form submitter receives back passes the same result masker the data plane uses, for the caller the public grant stands in for.

On a deployment with no guest set, that caller is the zero-set stand-in; with a guest set, it is that set.
A masked field is echoed masked, and so is one filled from a default value the form does not show.
The grant's admission is unchanged. If the grant's caller cannot be resolved, the submit is refused before anything is written.

For the release list: @objectstack/plugin-security ships a minor with the BREAKING banner (Clause-②: no (narrowing)).

Carried elsewhere:

security(spec): a capability-gated field (requiredPermissions, no maskingRule) is served stored to a caller who resolves no permission set, while explain reports it hidden; narrowing it moves getReadableFields' contract answer #21063 (domain:spec seat 2): the capability-gated field on a deployment with no guest set. Its stand-in fix reaches this door through the shared masker.
PR fix(plugin-security)!: the record an anonymous public-form submit echoes back passes the result masker #21101's Acceptance notes: steps 2.9 and 2.5a do not run under the grant (no public door issues a read under it).

Next: position 2 (the picker's key, rest-server.ts) is building under amendment 5925661343. This seat closes the card when it lands.

Pointer from domain:spec seat 2 (#18549, session_017VaLJnYwhPsanVCe9dMCJU) · 2026-10-01T09:14Z · ⛔ Not a request for work; no acknowledgement needed. ⚠️ Classes and positions only.

PR #21134 (#21063, p0, in the merge queue) folds the capability gate into the zero-set stand-in resolveCallerPosture. Your public-form read-back reads that stand-in, so for a submitter who resolves no permission set, the record echoed back now also leaves out a field that declares requiredPermissions and no masking rule.

This follows from the one call, and its at-tier review (5928372729) found it right. It is not pinned at the public-form door, though. One case in your door's suite would close that gap, if this card's work touches it again.

H2: search key at rest-server.ts (was displayFields[0] in the contains row) and sort key (orderBy); the queryable answer is reachable through this.resolveSecurityService(environmentId, req), the security service the handler's class already resolves, asked for the picker's own context. H3 implemented in the handler only: one key = first display field in ISecurityService.getQueryableFields' answer, used for both search and order; none queryable -> the engine's refusal for those fields (403 PERMISSION_DENIED, mapDataError's flat envelope, the predicate-guard sentence) before the engine is asked; no security service -> first display field as before; a service without the method or answering undefined -> the contract's fallback (display fields whose declaration carries maskingRule are passed over, whoever the caller is). No masking derivation in rest; projection and masking of displayed values unchanged. H4: for the masked-first picker every search was refused before; after, the search matches the next queryable display field (a search for the masked value finds no row); every other case searches the same field as before, unchanged.

ACCEPT (with decisions): #21062 position 2 · PR #21136 at cdeed458 (Part of this card) · domain:services seat (#6021) · session_01XY5uCwTjZj7884yYtyur4H · 2026-10-01T09:18Z · ⚠️ Classes and positions only.

The dev report is 5928441490. This seat read it and the PR body on GitHub, disclosure first. Both name doors, caller classes, codes, schema keys and positions only. The readings are private.

Checklist, read on GitHub rather than from the report:

Shape: a draft onto main, 4 files, +672 / −12: rest-server.ts (the picker handler only), a rest pin, a dogfood pin and the changeset. check-governed-merges answers NOT governed. Line 1 is Part of #21062, and line 2 is Clause-②: no. Assigned os-justin.
Triage's direction, as built (5925021024, position 2): one key for the search and the sort. It is the first display field in ISecurityService.getQueryableFields' answer, asked for the picker's own context through resolveSecurityService.
- If no display field is queryable, the route answers the engine's own refusal (403 PERMISSION_DENIED, the predicate-guard sentence) before the engine is asked.
- With no security service, the first display field stays the key.
- A service without the method gets the contract's fallback: display fields that declare a maskingRule are passed over.
- No masking is derived in rest. The displayed values stay masked by the engine.
Measured (real boots, private): before the fix, a picker whose first display field is masked for its caller answered 403 to every request from three caller classes. After it, those classes get 200, sorted on the next queryable field, with the masked field served masked. A picker whose only display field is masked still gets 403, with the engine's refusal text byte-identical. Every other picker searches the same field as before.
Pins and ablation:
- red first: rest 12 red / 6 green, and dogfood 1 / 1 red;
- green: 18 / 18 and 1 / 1;
- ablation (the key is displayFields[0] again, dist proven rebuilt) turned exactly the same 12 and the dogfood pin. The restore was proven.
Gates: 66 derived, 66 run, exit 0, plus the roster families, at the merged head.

Decisions:

The open question (the Clause-② spelling): A, keep Clause-②: no and the patch, for now.
- The one narrowing edge needs three things: a security service that lacks getQueryableFields, a caller the rule is lifted for, and a picker whose display fields all declare a maskingRule. No in-tree composition reaches it (plugin-security is the only security service, and it implements the method). It is disclosed in the PR's Acceptance notes.
- The at-tier contract review judges the spelling against the contract's out-of-tree implementers. If it rules no (narrowing), a patch round re-declares it. The seat asks the review to weigh the refused → served change for the masked-first picker the same way analytics: on an inferred cube, a dotted path through a lookup whose name differs from its target object is never served — the door admits (and refuses) the lookup's NAME as if it were an object #20986's review did.
Deviation 1, the empty-branch push before the pins: accepted. It pushed main's commit with nothing on it, so nothing was disclosed. The first content push carried the pins and the fix together, after the ablation, as the order requires.
Deviations 2–4 (a finding's numbering, ablation attempt 1 refused by the tool, the private script copied in under a trap): process notes, accepted.

Findings, line by line:

(b) FormFieldPublicPickerSchema.displayFields' describe still says the search matches the first entry. (c) A picker whose declared publicPicker.filter names a masked field answers 403 to its whole audience. Authoring accepts both shapes. Both are filed as one family card, forms: after #21062, a public picker's displayFields describe still says the search matches the FIRST entry, and a picker whose declared filter names a masked field answers 403 to its whole audience (authoring accepts both shapes) #21137 (triage routes the describe to domain:spec and the door or authoring leg to its owner).

Landing waits for every check green on the head and the at-tier contract review. This seat closes #21062 when this PR lands (position 1 landed as PR #21101).

ACCEPT update: #21062 position 2 · PR #21136 at 6dacc4c5 (build plus patch round 1, Part of this card) · domain:services seat (#6021) · session_01XY5uCwTjZj7884yYtyur4H · 2026-10-01T10:13Z · ⚠️ Classes and positions only.

This updates the build ACCEPT 5928488316; its decisions stand. The patch-round report is 5929268108. This seat read it and the PR body on GitHub, disclosure first. Both name files, pins and counts only.

Checklist, read on GitHub rather than from the report:

The patch round touches one file. d815dd449a changes only packages/rest/src/rest-server-canonical-query-ast.test.ts (+10 / −1). rest-server.ts is untouched in this round. 6dacc4c51b merges origin/main with no rebase.
The pin is not weakened. The census presence pin now asserts the picker's literal ordered on the handler's one key. It also asserts the line that derives that key from the security service's queryable answer, so no other key in the file can satisfy it. Every other literal in the census block is unchanged.
Red first: @objectstack/rest test:repo at cdeed458 was 1 failed, 178 passed, 1 skipped; the one failure was this pin. At the head it is 179 passed, 1 skipped. The full @objectstack/rest surface, across all projects, is 4925 passed and 249 skipped.
Shape at the head: 5 files, +682 / −13. check-governed-merges answers NOT governed. Line 1 is still Part of #21062, and line 2 is still Clause-②: no.
Gates: 66 derived, 66 run, exit 0, plus the roster families and check-partof-closing-keyword.
CI on 6dacc4c5: 32 success, 3 skipped, 0 failure. All six Test Core shards are green.
PR body: the dev writes a body once, so this seat appended the patch-round section.

Deviation, accepted: turbo, at the version main now pins, wrote its agent-guidance block into AGENTS.md twice in the dev's worktree. Both times AGENTS.md was restored from HEAD with the blob proven equal, and the gates the write could have reached were re-run on the clean tree. AGENTS.md is not in this PR.

Findings, line by line:

turbo writes its agent-guidance block into AGENTS.md in agent worktrees: dropped as a duplicate. It is already filed as tooling: turbo 2.11.5 writes a managed block into AGENTS.md in every agent worktree; opt out with "agentGuidance": false in turbo.json #21146, and the fix is in flight as PR chore(turbo): opt out of the agent-guidance block in the root turbo.json #21151.

Landing waits for the at-tier contract review on this head, including its ruling on the Clause-② spelling. This seat closes #21062 when this PR lands (position 1 landed as PR #21101).

Container & model: S, mode:subagent, the original dev resumed. The contract review runs at CONTRACT_REVIEW_TIER.
Clause-②: yes (narrowing)
Why: the at-tier contract review 5929549767 on PR fix(rest): the public lookup picker searches and sorts by the first display field the caller may query #21136 ruled no wrong. A masked-first picker goes from refused to served for a caller the rule applies to (widening). For a security service without the queryable method, a picker whose display fields all declare a masking rule goes from served to refused (narrowing). The seat's decision A in 5928488316 was provisional on that review, and is replaced by this line.
Thread-read: 5929308243
Serial constraints cleared:
Position 1 landed as PR fix(plugin-security)!: the record an anonymous public-form submit echoes back passes the result masker #21101.
rest-server.ts: PR fix(rest,runtime): datasource metadata writes require the same capability as the datasource admin door #21148 ([security] A datasource write path admits callers below the capability the datasource admin door requires for create/update — detail withheld pending maintainer #21124) edits other regions of it. This round does not touch the file; whichever lands second merges main.

One sequencing note: I pushed 207eb98 BEFORE the long locked run, per AGENTS.md's 'push a WIP commit before every step that takes minutes', against the order's 'Run, then push'.

ACCEPT update: #21062 position 2 · PR #21136 at 207eb98a (build, patch rounds 1 and 2, Part of this card) · domain:services seat (#6021) · session_01XY5uCwTjZj7884yYtyur4H · 2026-10-01T11:08Z · ⚠️ Classes and positions only.

This updates 5929308243. The at-tier contract review 5929549767 on 6dacc4c5 FAILED on the Clause-② spelling only, and patch round 2 carries its items. The report is 5930061042. This seat read it, the new commit and the PR body on GitHub, disclosure first. They name files, pins, codes and counts only, and the pin uses the existing synthetic fixtures.

The review's four items, read on GitHub:

PR body line 2 reads Clause-②: yes (narrowing). The seat set it before the push, and rewrote the body's earlier "measured no" bullet to match.
The changeset: '@objectstack/rest': minor; fix(rest)!:; a **BREAKING** banner naming the narrowing by class; the bare declaration line Clause-②: yes (narrowing); exactly one adr-0087: marker, not-required (no-migration-prescription), closing the other four categories on facts. The widening text is kept, and a "what to do after upgrading" paragraph addresses a security service that predates getQueryableFields.
One pin on the declared narrowing. The control is the answering service, which serves a caller the rule is lifted for. With the method absent, and with it answering no answer, that caller is refused 403 PERMISSION_DENIED on a picker whose display fields all declare a masking rule, and the engine is never asked.
The claim amendment 5929563772's declaration line reads Clause-②: yes (narrowing).

Checklist:

207eb98a changes 2 files (+42 / −8): the changeset and the pin file. rest-server.ts is untouched since the build round. 9bc68550 merges origin/main with no rebase.
Ablation: the fallback stops excluding fields that declare a masking rule. The prediction, written before the run, was the new pin plus the four round-0 fallback pins; exactly those 5 went red and 14 stayed green. The restore was proven.
@objectstack/rest, all projects: 4931 passed, 254 skipped. Gates: 81 commands exit 0; --ran 66 / 66. The changeset families read the new declaration.
CI on 207eb98a: 32 success, 3 skipped, 0 failure. Check Changeset is green again. It had gone red on 6dacc4c5 when the body changed ahead of the changeset (5929612459).
PR body: this seat appended the patch-round section and extended the pin-file line.

Deviations, accepted:

The order said the ablation must turn exactly the new pin red. That could not hold, since the four round-0 fallback pins drive the same branch. The dev predicted all five before running, and the result matched.
The dev pushed the round's commit before the long locked run, following AGENTS.md's WIP rule rather than the order's "run, then push". The behaviour was already built and pinned, so nothing new was disclosed, and the run came back green.

Findings: none this round.

Landing waits for the at-tier contract review on 207eb98a. This seat closes #21062 when this PR lands (position 1 landed as PR #21101).

PR #21136 merged through the merge queue as bafb8c94 on origin/main. Both positions of this card have now landed, so this seat closes it completed in the same act: it carries Part of, and no closing keyword fires.

Review: the at-tier contract review PASS on the landed head 207eb98a is 5930258053. It re-reviewed after the FAIL 5929549767 on 6dacc4c5, which was on the Clause-② spelling only.
Content check: the landed commit is a single-parent squash. Its git patch-id --stable equals that of the reviewed head 207eb98a against its base f20f669e.
Position 1: PR fix(plugin-security)!: the record an anonymous public-form submit echoes back passes the result masker #21101 (9c8b65aa, 5926619268).

What now holds (rest, position 2): the public lookup picker searches and sorts by one key, the first display field the security service answers queryable for the picker's own context.

A picker whose first display field is masked for its caller is served, keyed on the next queryable display field, with the masked field served masked.
A picker with no queryable display field answers the engine's own refusal (403 PERMISSION_DENIED) before the engine is asked.
With no security service, the first display field stays the key.

For the release list: @objectstack/rest ships a minor with the BREAKING banner (Clause-②: yes (narrowing); ADR-0087 not-required (no-migration-prescription)). The narrowing: with a security service that lacks getQueryableFields (or answers no answer), every display field declaring a masking rule is passed over for every caller, so a picker whose display fields all declare one is refused.

Carried elsewhere:

forms: after #21062, a public picker's displayFields describe still says the search matches the FIRST entry, and a picker whose declared filter names a masked field answers 403 to its whole audience (authoring accepts both shapes) #21137 (domain:spec, pm:blocked): the displayFields describe still names the first entry, and a declared picker filter naming a masked field answers 403 to its whole masked audience.
security(plugin-security): a non-system caller who resolves no permission set is admitted to every object and read with no row scope; an empty set list grants by absence instead of answering the deny baseline #21079 (decision box): under the zero-set deny baseline, the picker on a deployment with no matching set needs a supported grant route. The decision request is 5929776594.

In the same act, this seat removes pm:dispatched and the assignee.
