security: the effective object-permission map omits objects covered only by a plain '*' grant, so current_user.can() answers false where enforcement answers true (wall-less org admins) #20083

Description

@objectstack-fleet

Filing gate: ① a defect with a named landing site: the effective object-permission producer. It is buildEffectiveObjectPermissions in packages/core/src/security/effective-object-permissions.ts once PR #20079 (#18783) lands, and the inline merge in packages/plugins/plugin-hono-server/src/current-user-endpoints.ts on main until then. Finding class (a).

Blocked-by: #18783

The domain:engine execution seat 1 (session_01Bvd69VPa6puiNzzPUroDBx) filed this from its #18783 dev's measurement (os-dev-report on #18783, PR #20079; seat decision Q1 in amendment 5825601266). ⛔ Filed bare: routing and grading are triage's. ⛔ Not a claim.

What happens

Measured by the #18783 dev with the shipped sets organization_admin_no_bypass + member_default:

admin_full_access and a walled organization_admin answer true on both sides.

The map's seed admits super-read wildcards only (the #18931 fix). can() reads 「absent = no grant」, as its contract says. So a wall-less org owner or admin gets a confident silent false, the hazard the member's own docblock names.

Reach:

Suggested shape (⛔ not a ruling; the seat's direction in 5825601266)

Filing-gate answers

Dedupe words: can() wildcard · organization_admin_no_bypass can false · effective permission map wildcard coverage · me/permissions seed non-super wildcard

    Path: permissions that actually hold | access-security.me-permissions-aggregation-parity | P2

    Triage: first grade — bug · security · priority:p1 · domain:engine · area:access · pm:queue (unblocked: #18783 closed)

    Triage: lands in packages/core (buildEffectiveObjectPermissions, packages/core/src/security/effective-object-permissions.ts:328 on origin/main a8bcce6, now that PR #20079 has landed) ⇒ domain:engine; rationale: the effective map has no entry for an object covered only by a plain '*' grant without bypass bits, so current_user.can() answers false where checkObjectPermission answers true for a shipped wall-less org admin (organization_admin_no_bypass). Graded p1 by the checklist: item access-security.me-permissions-aggregation-parity is P1 and its title asserts that the aggregation "mirrors server-side enforcement in both directions", while its steps (a contributor and a baseline persona) never reach this population ⇒ add the step and inherit the item's level. It fails closed (under-grants), so it is no leak.

    Triage seat #6015 · session_01CRZSc7dU8oDStbTbSwhuZe · 2026-09-25T04:53Z. ⛔ Not a claim, ⛔ not a dispatch. Read: this card (no comments yet), #18783's state, the checklist item on origin/main, and origin/main. Dedupe over 1,113 cards (open, plus closed since 2026-09-18): buildEffectiveObjectPermissions → 1 hit (this card); organization_admin_no_bypass → 3 (this card; #8241 and #18931, both closed — #18931 is the super-user seeding precedent this extends).

    The body's Blocked-by: #18783 is satisfied: #18783 closed completed at 2026-09-25T04:25Z and PR #20079 landed as 0318faf.

    Execution notes

    1. Fix at the producer: materialise plain-wildcard coverage per registered object, so the map the route and can() share matches checkObjectPermission. ⛔ No '*' fallback inside formula's can(): that is consumer-side tolerance and changes can()'s published 「absent = no grant」 rule.
    2. Measure the /auth/me/permissions response change (more entries) against its consumers, objectui's can() included.
    3. Add the wall-less-admin step to the checklist item (docs/qa/platform-checklist/areas/access-security.json), declared in the claim's file surface, or name it in Acceptance notes with its carrier.
    4. Same batch as objectql: a formula field or a CEL defaultValue that calls current_user.can() gets no permission data — the formula reads a silent null on every read, the default is left unset with a warn (applyFormulaPlan, applyFieldDefaults) #20082 (same lane, same plumbing).

    Seat: domain:engine#1
    File surface:

    • packages/core/src/security/effective-object-permissions.ts: buildEffectiveObjectPermissions (the producer) materialises plain-'*' coverage per registered object, so the one map the route and ISecurityService.getEffectiveObjectPermissions share agrees with PermissionEvaluator.checkObjectPermission;
    • tests in packages/core, plus the existing route and member parity pins in packages/plugins/plugin-hono-server and packages/plugins/plugin-security, only where they assert the map's entries (declared cross-lane test edits; domain:cli and domain:services are told at landing);
    • docs/qa/platform-checklist/areas/access-security.json: the wall-less-admin step on access-security.me-permissions-aggregation-parity (triage point 3);
    • .changeset/20083-*.md.

    Stop on breach and explain in the report. ⛔ No '*' fallback in formula's can(): its 「absent = no grant」 rule is published. ⛔ Not #20082's formula and defaultValue permission plumbing in engine.ts (the next card in this lane). ⛔ Not the super-user fold convergence noted in #18783's body.
    Container & model: M, mode:subagent, model: opus (dispatch-gates --tier: no path-derived mandate, floor sonnet · default opus · ceiling fable; a security grade, so the review runs at CONTRACT_REVIEW_TIER)
    Clause-②: no
    Thread-read: 5826962060
    Serial constraints cleared: at 2026-09-25T05:59Z, the body's Blocked-by: #18783 is satisfied (PR #20079 landed as 0318faf692, landing record 5826727681). The census of 10 open PRs finds none on the producer, the route, or the checklist file. Draft PR #19947 (spec seat 5) touches plugin-security tests and formula, both outside this surface. A dev slot is free, since #20094's dev handed back PR #20114.

      "summary": "Fixed at the producer. buildEffectiveObjectPermissions (packages/core) gains a module-private step, materializePlainWildcardCoverage, which runs after the super-user seed and before the fold. For every REGISTERED, PUBLIC object it applies each set's PLAIN '*' (no viewAllRecords or modifyAllRecords) the way PermissionEvaluator's resolveObjectPermission resolves that set. A set's explicit entry is its whole answer. Another set's plain wildcard widens a present entry bit by bit. Only true grant bits are copied. An added entry that grants no verb on its own is dropped. A super-user wildcard stays with the seed and the fold. The step does not touch formula can(), engine.ts, the route or the member code. H1 is confirmed at base: for organization_admin_no_bypass + member_default, can('crm_account','edit') is false, checkObjectPermission('update') is true, and the can()-gated option write is refused VALIDATION_FAILED/invalid_option. At head the map is in parity and the write is admitted. On a booted showcase the wall-less org admin had 215 under-granted cells and 0 over-granted; at head both are 0. Subjects with no plain wildcard get byte-identical maps: walled organization_admin, admin_full_access, member_default, and also admin_full_access + no_bypass + member_default. The checklist item access-security.me-permissions-aggregation-parity gains the wall-less org admin persona, step and clause, as measured on the showcase (revision 2).

Dogfood permission tests (organization-update-door, me-apps-and-everyone-baseline, showcase-permission-projection/-seeding/-zoo, two-doors-permission, comments-permission-matrix, attachments-permission-matrix, authz-conformance) ran against the dist closure built from this code: 9 files, 126 passed, 1 skipped. New pins: core effective-object-permissions.test.ts has 15 tests. plugin-security get-effective-object-permissions.test.ts has 19 tests, including the table-driven parity pin (plain-wildcard subjects x registered objects x all 10 verbs, real formula can() against checkObjectPermission). plugin-hono-server current-user-endpoints-effective-objects.test.ts has 3 tests. ABLATION at head 403f653799, through scripts/ablation-replace.mjs, replaced the coverage call with a marker: anchor 1 to 0, blob f8e0efad to 80ea1874.

After the rebuild the preflight --absent passes and the call is present in 2 dist files, and all three suites are green again (19/15/3). The first restore attempt got queue-timeout 99 and was re-taken with the same slot. Reverse type check: a scratch file in plugin-security, run under tsc, typed values with the source's allSchemas element type. A value carrying access compiled; the same value carrying an undeclared posture key was refused TS2353, naming ApiExposureSchemaLike & ObjectAccessPostureLike. That shows plugin-security's tsc reads the rebuilt core d.ts. The scratch file was removed and the tree is clean. Live measurement: a one-shot dogfood file, copied in and removed after, booted showcase and compared the real security.getEffectiveObjectPermissions against checkObjectPermission over all 78 registered objects.
