fix(plugin-auth)!: session payload positions[] is the security axis, not the better-auth role scalar

[os-warren]

Fixes #15136

Implements the maintainer ruling recorded on the card (comment 5548477503, decision batch #39 item 2, verbatim 「同意」): option A — one name, one meaning. current_user.positions carries the security positions on every surface.

Round 2 — contract review returned FAIL on one blocking finding (a privilege-escalation path this PR would have introduced). Fixed, with the escalation pinned. See Round 2 below; the head is 9a26de3a6.

What was actually wrong

customSession (auth-manager.ts) built user.positions from a hand-rolled union — the better-auth sys_user.role scalar split on commas, the active membership mapped to org_*, and platform_admin — and read nothing from sys_user_position, the ADR-0057 D4 table that is the source of truth for custom positions.

The Console binds that array straight through as the CEL root current_user (objectui packages/app-shell/src/providers/expressionUser.ts:182 — positions: user.positions ?? [], a pass-through), so an action.visible narrowed by a business position answered FALSE for everyone, including the user who genuinely held it.

⭐ It failed silently and in the invisible direction. The root was bound and the key was present, so has(current_user.positions) was true, CEL raised nothing, and the predicate simply returned FALSE. A predicate that faults fails OPEN in the shell and would have shown the button; a successful FALSE shows nothing and reports nothing.

The finding that decided the fix

Triage recorded that the tree pointed two ways and that 「哪一轴才是 current_user.positions 的语义」 had no single answer in the tree. It does — it is written down. EvalUserSchema (packages/spec/src/identity/eval-user.zod.ts) already declared:

the signed-in user exposed to every predicate surface (server formula, server RLS, client UI gates) … with an identical shape … therefore evaluates identically wherever it is written

and its positions field: "built-in identity names + position names". The published docs promise the same — content/docs/permissions/permission-metadata.mdx:204 offers current_user.positions.exists(p, p == 'sales_manager'), a business position name.

So this is a declared contract being violated, not an ambiguous name. /auth/me/permissions (packages/plugins/plugin-hono-server/src/current-user-endpoints.ts, serving grants.positions) and every server-side evaluator (ExecutionContext.positions from resolveUserAuthzGrants) already resolved the security axis. The session payload was the one producer that did not.

Why nobody noticed: the documented example 'org_admin' in current_user.positions is the one name that sits on both axes. No example, test or doc in the tree could reveal the split.

The measured divergence

Evaluator surface	current_user.positions source	Content
Server formula / RLS / action body	ExecutionContext.positions from resolveUserAuthzGrants	security positions
/auth/me/permissions	grants.positions, same authority	security positions
Console UI (action.visible, visibleWhen, nav, page tabs)	get-session from customSession	auth roles — no sys_position, no everyone

The card reports action.visible; the divergence covers every client-side predicate surface. All are repaired by the one producer change.

The fix

The derivation is deleted, not repaired. resolve-authz-context.ts states that every entry point must resolve authorization through it and never re-read the sys_* grant tables itself — this callback was doing exactly what that forbids, which is how it drifted out of agreement in the first place. It now asks resolveUserAuthzGrants, scoped to the session's active organization. Same move isPlatformAdminUserId made at #10348.

Fails closed and warns on an unreadable grant store — matching what both halves of the old derivation already did silently.

---

Round 2 — the blocking finding, and what it changes

The escalation this PR would have introduced

Round 1 derived isPlatformAdmin as positions.includes('platform_admin'). ⛔ That is the exact form resolve-authz-context.ts forbids at hasPlatformAdminStanding:

Read the RUNG — never positions.includes(BUILTIN_IDENTITY_PLATFORM_ADMIN). The positions list is wider on purpose: an ADR-0057 D4 sys_user_position row may spell that very name, and a platform-RBAC assignment is not the D2 capability grant.

⭐ This PR is what made that dangerous. The array read was defensible while positions carried the auth axis, where nothing a tenant writes could put that word in it. Moving positions onto the security axis moved the string into a space a tenant admin can write: sys_user_position is apiEnabled, a tenant-level admin passes the ADR-0090 D12 gate outright, and a delegate passes assertAssignmentWrite's boundSets.every(...) vacuously for a position carrying no position-bound set.

Measured on the real pipeline — a plain org member plus a sys_user_position row spelled platform_admin:

	positions	isPlatformAdmin	judgePlatformAdmin	rung
pre-fix	[org_member]	false	false	false
round 1	[org_member, platform_admin, everyone]	true	true	false
round 2 (this)	[org_member, platform_admin, everyone]	false	false	false

The three agreed before this PR and disagreed after round 1 — admitting to the /admin/* mount gate.

What changed

1. auth-manager.ts derives the alias from grants.posture === 'PLATFORM_ADMIN' on the same envelope. That is byte-for-byte what hasPlatformAdminStanding returns (it is literally resolveUserAuthzGrants(...).posture === 'PLATFORM_ADMIN'), and derivePosture reads the capability grant, never the array — so payload, predicate and gate cannot disagree.
2. platform-admin-gate.ts:73 drops its positions.includes('platform_admin') leg. ⚠️ That line is pre-existing and is deliberately in scope: this PR is what moved the name into tenant-writable space, so any pre-existing reader that treats the name as authority became this card's problem. Removed rather than left unused.
3. Fixtures migrated — the ruling licensed exactly this ("fixtures to migrate, not evidence against the ruling"): admin-ban-endpoints.test.ts (the named one) and admin-sso-bridge-gate.test.ts (same species, four cases, found by running the suite). Both now carry the rung-derived alias and gain a case refusing the escalation shape.

The three-way-agreement pin, and its mutation

session-platform-admin-rung-agreement.test.ts drives a real session carrying a D4 row spelled platform_admin and requires isPlatformAdmin, judgePlatformAdmin and hasPlatformAdminStanding to agree on false, with a genuine unscoped admin_full_access grant as the control that they agree on true. One case asserts both shapes carry the name in positions[] and differ only on the rung — the finding, stated as an assertion.

⚠️ Its population, stated explicitly: it covers the D4-spelled-built-in-name shape plus a genuine-grant control. It does not cover the ADR-0091 validity window, the ADR-0049 catalogue flag, or the catalogue-page shapes — those are platform-admin-standing.consolidation.test.ts's population.

⭐ The lesson from round 1, recorded because it is the transferable part: I reported PIN 6 passing as "the mechanical proof that the authority's platform_admin derivation agrees with both gates shape for shape." PIN 6 does pass — but it has no case where a sys_user_position row spells the built-in name, so it was green throughout the window the escalation was live. A passing pin is proof of what it covers, never of the claim attached to it.

Mutation, proving the new pin can go red (both re-bound sites reverted; anchors asserted unique in the form written; trap … EXIT INT TERM):

Round-2 corrections to the round-1 claims

• Census, two rows added. objectui packages/app-shell/src/hooks/sharedUserFeeds.ts:507 and apps/console/src/services/approvalsApi.ts:394 both mint role:<position> approver identities from user.positions. Verified: both want position names and the server matches them against resolver positions, so both are repaired, not broken — no re-binding owed. (approvalsApi.ts also splits user.role itself, which is why the no-array decision costs it nothing.) They belong in the table because "every in-repo reader" is a claim about the whole set.
• check:role-word attribution corrected. That gate ratchets the reserved word in content/docs / skills/ prose; the identifier ban over authored metadata lives in packages/lint. A TypeScript payload key trips neither mechanically until documented. The ADR-0090 D3 prohibition is what rules against minting roles — the conclusion stands, round 1's wording conflated two gates.
• PIN 3 scoped. It compared the payload against the unscoped resolver, which agrees only on a single-org fixture; it now reads tenantId off the session.
• Changeset carve-out, measured. "membership-derived names are unaffected" was unqualified. With no active organization the resolver projects every membership, so those names are now added: [] → [org_admin, everyone]. Pinned. ⚠️ My first attempt at that pin failed — the default fixture does stamp an active org, a different branch — which is why it is measured rather than asserted.
• Path corrected: current-user-endpoints.ts is in plugin-hono-server, not plugin-auth.

plugin-auth/src/platform-admin-gate.ts:73	positions.includes('platform_admin')	⛔ re-bound in round 2 — the escalation path
plugin-auth/src/auth-manager.ts (isPlatformAdmin)	was positions.includes(...)	⛔ re-bound in round 2 — reads the rung
objectui packages/auth/src/useWorkspaceAdminStatus.ts:121	positions.some(isAdminRole)	✅ satisfied; its other two legs read user.role / member.role directly
objectui packages/auth/src/AuthGuard.tsx:78	requiredRoles.some(r => positions.includes(r))	app-supplied prop; no in-repo caller

apps/console/src/services/approvalsApi.ts:394	role:<position> identities	✅ repaired by the new axis

Authored expression sites: packages/spec/src/conversions/registry.ts:1845,1858,1880 (position names — start working); examples/app-showcase/.../cascading-select.object.ts:85 ('admin' — see below); docs (position names — contract restored).

⛔ objectui needs no functional change — its binding is a pure pass-through, so no cross-lane card is split there.

Why no renamed array

The ruling said the auth-role array "stays available under its own name (the dev proposes it — roles is the natural one)". Measured, I propose no new array — the one place I depart from the ruling's wording:

1. Everything the old union contributed beyond the security axis was the sys_user.role scalar's own tokens (org_* and platform_admin are on both axes).
2. That scalar is already published, unchanged, as user.role (ADR-0068 D2 pins it is never overwritten).
3. ADR-0090 D3 makes "role" a reserved-forbidden word with a single carve-out for better-auth's own schema — which a key we mint does not qualify for. Zero consumers need it per the census.

If the maintainer wants the array anyway, it is an additive follow-up; nothing here forecloses it.

Reproduction, inverted

session-positions-security-axis.test.ts drives the real pipeline on both sides — a real better-auth instance answering a real getSession(), and the real celEngine from @objectstack/formula over that payload. A demo_reviewer holder sees the button; a bystander on the same engine does not; removing the assignment row hides it again; has(current_user.positions) stays true and the predicate never faults, so a "fix" that merely made it fault (failing OPEN) could not pass. Round-1 ablation restoring the pre-fix union: ABLATION_VITEST_EXIT=1, headline {"ok":true,"value":false} — a successful FALSE, not a fault.

@objectstack/formula is a plugin-auth devDependency for that half; it depends only on cel-js + spec, so there is no cycle.

Out of scope, filed separately

examples/app-showcase/.../cascading-select.object.ts:85 gates on 'admin' in current_user.positions while its comment claims the server rejects a non-admin. 'admin' is not a built-in identity name — a membership admin is projected as org_admin — so server-side that comparand never matched. Pre-existing, opposite direction, and it does not self-heal once this lands. Filed bare as #15943 with the measurement.

What this run could not see

• 1 changed file(s) yielded no anchor (packages/plugins/plugin-auth/vitest.config.ts) — pages documenting those are invisible to this run
• 4 name(s) were too generic to anchor anything (single lowercase words)
• the SDK route bridge reached 61 of 219 client-bound route-ledger rows — the other 158 have no registrar path: tail to select them, so pages documenting THEIR client methods cannot appear above, on this or any run. Of those 158: 0 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 56 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 102 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run. Measured on fix(driver-sql): emit varchar(maxLength) for a text field a declared index keys on #11430: content/docs/protocol/objectql/types.mdx documents the text-family column mapping by the ObjectQL type names it maps FROM (text / textarea / html) while the diff changed createColumn; it went unlisted, and it was the page that diff falsified, in four places. No shared token exists to detect this on, so a rule your change carries has to be re-read by hand in the pages that restate it.

Coarse fallback — 133 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json f50c394da55846da8d38f1e1efadbc24faa26ce2 → packageMentionDocs.

Which tree this was computed on

This run read content/docs from 524b793fcdcc3f2b4b54c60e8eb3dc5088a32d87 — the merge of head 87040f33285e31e8ab8504bdb4a0c83ff12ff908 into base f50c394da55846da8d38f1e1efadbc24faa26ce2, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

---

1. positions carries the security axis on the real pipeline — PASS

• The PR's suite, re-run on the real auth.api.getSession() + real celEngine: NEWSUITE_EXIT=0, 18/18.
• Own measurements on the same real pipeline (real better-auth over a real AuthManager, memory engine from the imported sibling double), values recorded to disk, not read off assertions:
  • R3 (multi-org: owner of org_a, member of org_b, sys_user_position bound to org_b, session stamped org_a): payload [everyone, org_owner] == resolveUserAuthzGrants(…, {tenantId:'org_a'}); the unscoped resolver answers [b_only_reviewer, everyone, org_member, org_owner]. So the payload is tenant-scoped exactly as /auth/me/permissions scopes it (plugin-hono-server/src/current-user-endpoints.ts:576-598 — note the PR body cites this file under plugin-auth; the path is wrong, the line is right) and as resolveAuthzContext scopes ExecutionContext.positions (resolve-authz-context.ts:427,452).
  • R4 (plugins:{admin:true}, sys_user.role='manager,admin', sys_member.role='admin,custom_lead'): post-fix positions [org_admin, custom_lead, everyone], role 'manager,admin'.
• Ablation (pre-fix blob restored under trap … EXIT INT TERM, absolute paths): BEFORE=0fae6997… (== HEAD blob, asserted before writing), anchors resolveUserAuthzGrants(dataEngine…)=1/const activeOrgRoles=0 → after swap AFTER=30ee8736…, anchors 0/1. ABLATION_VITEST_EXIT=1 → Tests 4 failed | 29 passed, headline AssertionError: {"ok":true,"value":false}: expected … to match object { ok: true, value: true } — the silent FALSE, reproduced. Pre-fix R4 positions: [manager, admin, org_admin, custom_lead]. Restore: RESTORED_BLOB=0fae6997…, git diff HEAD empty.
• ⚠️ Non-blocking pin weakness: PIN 3 compares the payload against the unscoped resolveUserAuthzGrants(engine, holderId). That agrees only because the fixture has one org — R3 shows the two references diverge for a multi-org user. The pin should pass tenantId: session.activeOrganizationId, or a scoping regression would pass it.

2. isPlatformAdmin derived from the array vs the other gate — BLOCKING

PIN 6 is genuinely unmodified (blob 1e1d6fc2… at base, head and disk) and genuinely green (PIN6FILE_EXIT=0, 37/37). But it has no case for the one shape the authority itself warns about. resolve-authz-context.ts:1125-1129, on hasPlatformAdminStanding:

⛔ Read the RUNG — never positions.includes(BUILTIN_IDENTITY_PLATFORM_ADMIN). The positions list is wider on purpose: an ADR-0057 D4 sys_user_position row may spell that very name, and a platform-RBAC assignment is not the D2 capability grant.

The new auth-manager.ts:3633 is exactly positions.includes(BUILTIN_IDENTITY_PLATFORM_ADMIN), while isPlatformAdminUserId (:6285, still live at :1867 for /sso/register and :3220 for impersonation) reads the rung. Measured, real pipeline (R1): a plain org member plus sys_user_position {position:'platform_admin', organization_id:null}:

	payload.positions	payload.isPlatformAdmin	isPlatformAdminUser(session.user)	hasPlatformAdminStanding (rung)
pre-fix (ablation)	[org_member]	false	false	false
this PR	[org_member, platform_admin, everyone]	true	true	false
R5 control (genuine unscoped admin_full_access)	[platform_admin, everyone] both	true both	—	true both

The gates agreed before this PR and disagree after it. Consequence: judgePlatformAdmin(session) — fed by authApi.getSession(), i.e. this payload — is the gate on the /admin/* mount (auth-plugin.ts:2247, gateAdmin at :2302 for the four /admin/sso/* bridges and the #2766 admin-user block, :2369). Reachability: sys_user_position is apiEnabled: true; the D12 gate passes tenant-level admins outright (delegated-admin-gate.ts:8-12), and for delegates allPositions() filters only the everyone/guest anchors (:336-340) while assertAssignmentWrite's test is boundSets.every(...) — vacuous for the seeded platform_admin position, which has no position-bound set (its standing is the user-level grant). So a tenant admin, or a delegate holding manageAssignments and a BU anchor, can self-assign platform_admin and the session gate then admits them to platform-operator routes. That is the privilege-shaped regression this item was flagged for. (Impersonation is not exposed: admin-impersonate-endpoint.ts:205-213 documents that it reads the raw row plus the oracle.)

Two readers of the old meaning ("platform_admin in positions ⇔ the rung") that the census marked satisfied: the new derivation at :3633, and platform-admin-gate.ts:73 — whose census row was evaluated only in the admit direction. Under ruling A positions is wider by definition, so both need re-binding in this PR:

• const platformAdmin = grants.posture === 'PLATFORM_ADMIN' — the rung, from the same envelope (UserAuthzGrants.posture, :608), still one authority and one call;
• isPlatformAdminUser drops its positions.includes('platform_admin') leg (keep isPlatformAdmin === true + the legacy scalar). Its fixture admin-ban-endpoints.test.ts:172-179 pins that leg with positions:['user','platform_admin'] and no isPlatformAdmin — one of the two fixtures the ruling named for migration;
• a pin for the R1 shape: D4 row spelled platform_admin → payload isPlatformAdmin:false, judgePlatformAdmin refuses, rung false — three-way agreement, with R5 as its control.

For the record: ADR-0068 D2 does define the alias as 'platform_admin' in roles (docs/adr/0068…:71), so the dev's citation is accurate — it predates D4 rows being able to spell built-in names, and core's later ⛔ is the specific rule; the measurement is why.

3. Zone-2 census — incomplete; two rows to correct (not blocking on its own)

Re-derived with grep -rn "user?\.positions|positions\.(some|includes)|positions: user" over both repos (control: the same grep returns the four rows the PR lists). Additional in-repo readers of get-session's user.positions the table omits:

• objectui packages/app-shell/src/hooks/sharedUserFeeds.ts:507 and apps/console/src/services/approvalsApi.ts:394 — both mint role:<p> approver identities from user.positions. Their own docstrings say they want position names (manager, finance_approver); the server matches role:<p> against context.positions from the resolver (approval-service.ts:1089, resolver-sourced, never client-supplied). So they were reading the wrong axis before and are repaired, not broken, by this PR — but "every in-repo reader" lists 4 of 6 objectui sites, and the ruling's census requirement is a claim about the whole set.
• platform-admin-gate.ts:73 — listed, but see item 2.
• The ruling named admin-ban-endpoints.test.ts:176, :201 as fixtures to migrate; the file is untouched (ad17e502… at base == head). :176 still pins positions:['user','platform_admin'], a shape the producer no longer emits, and it is precisely the positions-leg fixture in item 2.
• objectui useWorkspaceAdminStatus.ts:100-108 docstring ("the window is every session that reaches the console without that stamp") goes stale — see R2 below. Comment-only; no objectui functional change is needed, so no cross-lane card.

4. The deviation's premises — hold, with one scope nuance (reported, not ruled)

• (a) old union's extra content = the scalar's tokens: measured. R4 pre [manager, admin, org_admin, custom_lead] → post [org_admin, custom_lead, everyone]; membership projection is the identical code (comma-split + mapMembershipRole, resolver :817-823, default arm passes a custom token through — custom_lead survives on both sides). Holds. ⚠️ R2 (session with no active org, autoActiveOrganization:false, sys_member.role='admin'): pre [] → post [org_admin, everyone], because the resolver projects every membership when tenantId is undefined (:815). New ⊋ old∖scalar; the premise (old's surplus is only the scalar) still holds, but see item 5.
• (b) user.role published unchanged: R4 role:'manager,admin' on the real payload; :3651 spreads ...user. Holds.
• (c) ADR-0090 D3 real, check:role-word carries a ratchet: docs/adr/0090…:176-200 — "role is a reserved-forbidden word in identifiers, UI copy, and documentation, enforced by lint. Single documented exception: the better-auth boundary". scripts/check-role-word.mjs + scripts/role-word-baseline.json (44 files / 123 occurrences); --self-test exit 0, real run exit 0. Nuance: check:role-word ratchets content/docs and skills/ prose; the identifier ban is packages/lint/src/validate-security-posture.ts:153-159 over authored metadata names/labels (tokens role/roles). A TS payload key roles trips neither mechanically until it is documented — the PR's "revive the exact banned identifier check:role-word ratchets against" conflates the two gates. The ADR-level premise holds; the mechanical one is docs-side.
• (d) zero consumers need an array form: survives the census correction — the two omitted readers want position names, and approvalsApi.ts:396 already splits user.role itself.

5. Changeset — standing guard: one unqualified claim

• "a name in sys_member.role is still projected, so membership-derived names are unaffected" — unqualified. Carve-out needed: for sessions carrying no active organization, membership names are now added, from every membership (R2 [] → [org_admin, everyone]).
• "pinned shape for shape … PIN 6, which passes unchanged" — true as measured, but PIN 6's set has no D4-spelled-name case; once item 2 is fixed, name the new pin here.
• The rest names the changed meaning plainly; a release-notes reader learns their predicates may flip. ADR-0087 registration verified by the PM; spec check:migration-registry exit 0 (157 semantic); changeset marker id == registry entry id.

6. Spec half — PASS

Merge-base eval-user.zod.ts:9-14 already said "every predicate surface … identical shape … evaluates identically wherever it is written" and :193 "built-in identity names + position names" — the declared-contract-violated reading holds; this is a bug fix, not a redefinition. spec check:docs exit 0 (230 generated files in sync — eval-user.mdx is generated and matches), spec check:generated exit 0 (All 15 generated artifacts are up to date). Registry entry, changeset and code comment say the same thing.

7. Single pass-through — PASS

AppContent.tsx:924 <ExpressionProvider user={buildExpressionUser(user)}> (also :660 for nav, RecordFormPage.tsx:301) → buildExpressionScope (ExpressionProvider.tsx:88: current_user: user) → PredicateScopeProvider → every usePredicateScope() consumer: containers.tsx:468 (actions), SchemaRenderer.tsx:647 (page tabs), form.tsx:1213 (visibleWhen), KanbanImpl.tsx:122, KanbanEnhanced.tsx:90, data-table.tsx:397/448. expressionUser.ts:182 is positions: user.positions ?? []. No other objectui path constructs current_user; one producer fix reaches all of them.

Addendum to the contract review above — closing one NOT MEASURED row. The full @objectstack/plugin-auth suite finished after posting: pnpm test (single redirected run, scratch suite removed first) → FULL_EXIT=0, Test Files 99 passed (99), Tests 2101 passed (2101) — matching the dev's figures. Nothing in it changes the verdict: the item-2 shape (a D4 sys_user_position row spelled platform_admin) is covered by no existing pin, which is why a green suite and a privilege-shaped regression coexist here. FAIL stands; re-review on the next push.

PM — held. Rework dispatched, and the scope expansion the fix needs is authorized here

The blocking finding stands and I am not looking for a way around it. ⇒ This PR would introduce a privilege-escalation path that does not exist on main. Pre-fix, the ablation shows isPlatformAdmin, judgePlatformAdmin and hasPlatformAdminStanding all answer false for the constructed user; post-fix the first two answer true while the rung still says false. A disagreement between two gates over who is a platform admin is not a nit, and the reachability was established rather than assumed — sys_user_position is apiEnabled, tenant admins clear the D12 gate outright, and a delegate clears assertAssignmentWrite's boundSets.every(...) vacuously because the seeded platform_admin position has no bound sets.

⭐ This is the finding the whole review round existed for. I weighted isPlatformAdmin as "the real regression risk in the change" when dispatching, and asked for PIN 6 to be checked. PIN 6 is unchanged and green — and it did not catch this.

The lesson worth more than the fix

The implementer reported PIN 6 as "the mechanical proof that the authority's platform_admin derivation agrees with both gates shape for shape." The pin passes; the claim attached to it was broader than its population, because nothing in it constructs a sys_user_position row that spells the built-in name. ⇒ A passing pin proves what it covers, never the sentence written above it. That is the same failure this session has now seen five times in changeset prose — a claim quantified over a set the author had only sampled — arriving this time through a test rather than a sentence.

⚠️ Why a pre-existing line is in scope, stated so it does not read as scope creep

positions.includes('platform_admin') at platform-admin-gate.ts:73 predates this PR and was defensible while positions carried the auth axis, where no tenant can make the platform say that word. This PR moves positions to the security axis, where an ADR-0057 D4 row is a tenant-writable string. ⇒ The PR does not merely coexist with that line — it changes what the line reads. Any pre-existing reader that treats a name in positions as authority is in scope for this card, in the diff or not, and the rework brief says so.

Migrating admin-ban-endpoints.test.ts:176 is likewise not scope creep: the ruling names it and :201 explicitly as "fixtures to migrate, not evidence against the ruling."

Ruled and unchanged by this FAIL

Ruling A on the auth-role array stands. The review measured all four of its premises and they hold: the old union's surplus was exactly manager, admin; user.role is published unchanged; ADR-0090 D3 and the check:role-word ratchet baseline are real. ⇒ No new array. One wording correction the rework carries: check:role-word ratchets docs prose, while the identifier ban lives in packages/lint over authored metadata — the conclusion survives, the PR's conflation of the two does not.

Item 5 is a second instance of the standing guard doing its job: "membership-derived names are unaffected" is false for a session with no active org, which now gains org_* from every membership ([] → [org_admin, everyone]). Measured. That needs a named set or a carve-out in the changeset before this lands.

What comes back

A rework, not a fix-up — and ⛔ this one gets a second review round, because the change is behavioural and security-shaped. Required: derive the alias from the rung (grants.posture === 'PLATFORM_ADMIN'), drop the positions leg from isPlatformAdminUser, migrate the named fixture, and add a three-way-agreement pin driven with a sys_user_position row spelled platform_admin present — ⛔ mutated, because a pin that cannot go red on the escalation is not a pin.

Recorded with thanks for the two ride-along corrections that cost the review extra work and were not asked for: the census omission of objectui sharedUserFeeds.ts:507 / approvalsApi.ts:394 (both repaired by the new axis, not broken — so no re-binding is owed, but a census should not be silent about them), and the addendum closing the full-suite row (99 files / 2101 tests, exit 0) rather than leaving a stale NOT MEASURED standing.

Contract review, round 2 (Clause-②: yes, needs:contract-review) — verdict: PASS

Tier (override + self-report). CONTRACT_REVIEW_TIER = 'claude-fable-5-1' at scripts/pm/dispatch-gates.mjs:9852. This Agent call carries an explicit model: fable override attested by the PM seat; I self-report as claude-fable-5-1. Not an exact-match reading; get_session was not called.

Independence. Dev line claude/issue-15136-positions-security-axis from a separate os-dev subagent of the same PM session — a branch, not the self-review case. Round 1 (comment 5553063816 + addendum 5553069316) was a different reviewer; I re-took its blocking leg rather than trusting either report.

Subject. Head 9a26de3a617ec59015b91f112f9bebbb9b0252b3, merge-base 3f89967e35acd69cbd9be7310fdb6ee6d83ca93e, 14 files. Own detached worktree /home/user/objectstack-review-15948-r2 (pnpm install --frozen-lockfile exit 0; pnpm --filter "@objectstack/plugin-auth..." build exit 0). Every exit code below is off a single redirected command. Already verified by the PM and not redone: the constant-based read is gone (2× at e580aa429, 0× at head; one assignment at auth-manager.ts:3640), the gate's positions leg is gone, ADR-0087 registration exit 0.

---

1. Is the escalation closed on the real pipeline? — PASS, measured

Own scratch suite (real better-auth over a real AuthManager, real auth.api.getSession(), memory engine from the sibling double; values written to disk, not read off assertions). A plain member of org_a, session stamped activeOrganizationId = org_a in every row:

shape	positions	isPlatformAdmin	isPlatformAdminUser	judgePlatformAdmin	rung	posture scoped / unscoped
D4 row platform_admin, organization_id: null (dev's shape)	[org_member, platform_admin, everyone]	false	false	false · 403	false	MEMBER / MEMBER
D4 row platform_admin, organization_id: org_a (what a tenant admin most naturally writes)	same	false	false	false · 403	false	MEMBER / MEMBER
the tenant admin themself (sys_member.role='admin') + D4 row	[org_admin, platform_admin, everyone]	false	false	false · 403	false	MEMBER / MEMBER
D4 rows spelled platform_admin in both orgs, member of both	[org_member, platform_admin, everyone]	false	false	false · 403	false	MEMBER / MEMBER
admin_full_access grant scoped to org_a	[org_member, everyone]	false	false	false · 403	false	MEMBER / MEMBER
control: genuine unscoped admin_full_access	[platform_admin, org_member, everyone]	true	true	true · 200	true	PLATFORM_ADMIN / PLATFORM_ADMIN
control: same grant, member of org_a + org_b, active org_a	same	true	true	true · 200	true	PLATFORM_ADMIN / PLATFORM_ADMIN

The name is in positions[] on every escalation row (the premise is not vacuous) and no construction obtains platform standing from a tenant-writable name. Scratch exit 0, 24/24; the file was removed before the full-suite run below.

2. Is grants.posture === 'PLATFORM_ADMIN' the rung? — PASS, both halves in source

• hasPlatformAdminStanding (core/src/security/resolve-authz-context.ts:1148-1156) is literally resolveUserAuthzGrants(ql, userId, { nowMs }).posture === 'PLATFORM_ADMIN'.
• grants.posture = derivePosture({ isPlatformAdmin: hasPlatformAdminGrant, isTenantAdmin: … }) (:1071); derivePosture (posture-ladder.ts:103-107) reads only those two booleans — no positions read anywhere in posture-ladder.ts.
• hasPlatformAdminGrant flips true at exactly two sites: :955 (an admin_full_access set whose id is in unscopedUserPsIds, i.e. a sys_user_permission_set row with organization_id === null) and :1011 (configured admin emails). Neither touches the array. The fix removes the defect; it does not relocate it.
• ⚠️ One nuance the "byte-for-byte" wording glosses: the payload resolves scoped (tenantId: activeOrganizationId), the rung resolves unscoped. That cannot move the rung — unscopedUserPsIds is filtered on organization_id === null before tenantId is consulted — and the table above measures it: scoped and unscoped posture agree on all seven shapes, and an org-scoped admin_full_access grant is MEMBER on both.

3. The three-way pin, and whether it goes red — PASS, three legs re-taken

Harness: anchors asserted unique in the form written (grep -cxF, whole line; my first spelling was off by two spaces and the harness refused before touching disk — AM_ANCHOR_N=0), blobs checked against HEAD: before writing, marker MUT15948R2, restore under trap … EXIT INT TERM. Head blobs AM=4a097c477a…, GATE=409d8e1b26… (same as the dev reported).

leg	mutation	on-disk proof	vitest	failures
M1 both sites → array read	AM_AFTER=10f14c49fc…, GATE_AFTER=e87414a7b8…	INJECTED_MARKERS=2, REMAINING_RUNG_ASSIGNMENTS=0, GATE_POSITIONS_LEGS=1	exit 1, 4 failed / 13 passed	the 3 name-only refusals + the indistinguishability case; headline positions=["org_member","platform_admin","everyone"]: expected {alias, gate, rung} to deeply equal {alias:false, gate:false, …}
M2 gate leg only	AM_AFTER=4a097c477a… (untouched), GATE_AFTER=e87414a7b8…	markers 1, rung assignments 1, legs 1	exit 1, 9 failed / 51 passed (60)	4 pin + 4 SSO-bridge refusals (register, register-saml, request-domain-verification, verify-domain) + 1 ban refusal — exactly the predicted 9
M3 alias site only	AM_AFTER=10f14c49fc…, GATE_AFTER=409d8e1b26… (untouched)	markers 1, rung assignments 0, legs 0	exit 1, 4 failed / 13 passed	same 4 as M1 — the gate reads u.isPlatformAdmin === true downstream of the payload, so re-binding the alias alone reopens /admin/*

Each leg restored: RESTORE_AM/RESTORE_GATE == HEAD: blobs, git diff HEAD 0 lines, markers 0/0. M2 and M3 together show each re-bound site is independently load-bearing and independently pinned.

⭐ Population of the pin, stated. The file reports 17 tests; 7 are its own (4 name-only refusals incl. the premise, 2 genuine-grant controls, 1 indistinguishability), the other 10 come from the sibling module it imports for the engine double. Its shape is a D4 row with organization_id: null on a single-org member; the org-scoped row, the tenant-admin holder and the two-org shape are covered by my scratch measurements above, not by the pin. The ADR-0091 window / ADR-0049 flag shapes remain PIN 6's population, as the file itself says.

4. The fixture family — closed; re-derived

• Consumers of isPlatformAdminUser / judgePlatformAdmin, repo-wide over *.ts|tsx|mjs|js excluding node_modules/dist: 12 files, all under packages/plugins/plugin-auth/src (control: the gate file itself returns 5). objectui: 0.
• Test fixtures building a platform admin from positions spelled platform_admin under those consumers: admin-ban-endpoints.test.ts (1 case) and admin-sso-bridge-gate.test.ts (4 cases through one SESSIONS map) — both migrated to carry the alias, both gain the refusal shape, and M2 reds all five refusals. Every other consumer test builds its admin from a real ADMIN_FULL_ACCESS row (admin-has-permission-endpoint.test.ts:131-132, admin-impersonate-endpoint.test.ts); the remaining string matches are comments (admin-impersonate-endpoint.test.ts:7, admin-remove-user-gate-ordering.test.ts:102). No fifth.
• Server-side readers of the session payload's positions/isPlatformAdmin outside plugin-auth: none — runtime/src/security/resolve-session-principal.ts only calls getSession; sandbox/body-runner.ts:278 reads a hook-engine session, not the auth payload. objectui expressionUser.ts:176 passes isPlatformAdmin through (rung-derived), not re-derived via createEvalUser; useWorkspaceAdminStatus.ts:121 still admits UI affordances on the name — UI-only, the round-1 row stands.

⚠️ Same species, pre-existing on main, out of this PR's scope — recommend a follow-up card. Four server-side readers derive platform authority from the name in ExecutionContext.positions: plugin-sharing/src/sharing-rule-service.ts:254 (hasPlatformAuthority), plugin-approvals/src/approval-service.ts:976 (admin override, alongside posture), runtime/src/domains/activation-gate.ts:149 (bypass), plugin-security/src/explain-engine.ts:117 (posture derivation). ExecutionContext.positions is resolver-sourced on main and the resolver's §4 D4 projection is untouched by this PR, so a D4 row spelled platform_admin already reaches them today; this PR neither widens nor narrows that, and ctx.posture is already carried (:592) for them to read instead. Reachability through the D12 channel was established in round 1 and not re-derived here. Nearest existing card is #11978 (a different census). Not blocking.

5. The org-less carve-out — PASS, measured

Changeset lines 94–102 now name the carve-out with its set ([] → [org_admin, everyone]) and qualify the "unchanged" to the active-org branch. The pin asserts activeOrganizationId falsy before reading positions, so it drives the branch it claims. My measurement: autoActiveOrganization: false + one sys_member.role='admin' → activeOrg=null, positions=[everyone, org_admin], alias false; the default manager on identical rows → activeOrg=org_a, [everyone, org_admin] — the other branch, which is why the dev's first attempt failed.

6. PIN 3 scoping — PASS

Source: tenantId: session.session.activeOrganizationId read off the envelope. Not vacuous: every default fixture stamps an active org (measured above), and my envelope-agreement leg holds payload.positions == resolveUserAuthzGrants(tenantId: activeOrg).positions set-for-set on four shapes, with alias == (scopedPosture === 'PLATFORM_ADMIN') == rung.

7. Prose — one correction, non-blocking

• Changeset: every "unchanged / still" is qualified — user.role (ADR-0068 D2, measured in round 1 R4), PIN 6's named shapes, the explicit no-active-org carve-out. check:role-word attribution corrected (lines 64–68) and it matches the tree: scripts/check-role-word.mjs:67 ROOTS = ['content/docs', 'skills']; the identifier ban is packages/lint/src/validate-security-posture.ts:153-165. No roles key minted.
• ⚠️ PR body: "spec source is unchanged since [round 1]" is false as written on this head — git diff e580aa429 HEAD -- packages/spec/src names 11 files (automation / i18n), moved by the origin/main merge. The PR's own three spec edits are byte-identical to round 1 (0 diff lines on eval-user.zod.ts, migration 18, registry.ts), which is the defensible sentence. The round-1 spec green is therefore not evidence for this head; see the ledger for what I ran instead.

8. Declared NOT MEASURED — sanity-checked

spec check:authorable-surface exit 0 (1603 schemas), spec check:docs exit 0 (230 in sync), spec check:migration-registry exit 0 (157 semantic), check-role-word --self-test / real 0 / 0, check-nul-bytes exit 0 (7704 files).

Addendum to the round-2 contract review above — closing both NOT MEASURED rows. Both runs completed with their exit markers written (no truncated log was read as a result); each exit is off a single redirected command. The dependency closure was built at this head before any run (pnpm --filter "@objectstack/plugin-auth..." build exit 0, which includes spec, core, formula dist/), so neither row measured a stale artefact.

Command (head 9a26de3a6)	Exit	Verdict line

pnpm --filter @objectstack/spec test	0	Test Files 477 passed (477) · Tests 12818 passed (12818) · 687s

On the spec row: I ran it rather than accept the round-1 green, because the PR body's "spec source is unchanged since" does not hold on this head — git diff --name-status e580aa429 HEAD -- packages/spec/src names 11 files, including one added test file (automation/end-node-outcome.test.ts) and three modified ones, brought in by the origin/main merge. The 476 → 477 files / 12787 → 12818 tests delta is exactly that. The PR's own three spec edits are byte-identical to round 1; the spec tree they sit in is not, and it is green.

Nothing here changes the verdict — PASS stands, with the two non-blocking items already on record (the PR-body wording above, and the pre-existing server-side name readers as a follow-up card).

PM sign-off — round 2 PASS, undrafted and armed

Both ledger rows the reviewer left open are now closed by its addendum, and I held the undraft until they were. ⚠️ Round 1 of this PR would have shipped a privilege escalation; a PASS with two open rows was not going to be enough here.

What was actually established

The escalation is closed against seven constructions, not one. A D4 row spelling platform_admin — global, org-scoped, held by the tenant admin themself, and present in both orgs — plus an org-scoped admin_full_access grant: every one answers isPlatformAdmin=false, isPlatformAdminUser=false, judgePlatformAdmin=false·403, rung false, posture MEMBER, with the name still sitting in positions[]. Both genuine-grant controls answer true across the board. ⭐ That the name is still present while every gate says no is the shape that matters: the fix is not filtering the name out, it is refusing to treat a name as authority.

Alias ≡ rung, verified in source rather than asserted. hasPlatformAdminStanding is resolveUserAuthzGrants(...).posture === 'PLATFORM_ADMIN'; derivePosture reads only a boolean; hasPlatformAdminGrant flips only at resolve-authz-context.ts:955 (an unscoped admin_full_access row) or :1011 (config emails). One nuance the reviewer named rather than glossed: the payload resolves scoped and the rung unscoped, and it showed they cannot diverge.

Every re-bound site is independently load-bearing and independently pinned. M1 (both sites) → 4 failed; M2 (gate leg only) → 9 failed = 4 pin + 4 SSO-bridge refusals + 1 ban refusal; M3 (alias only) → 4 failed. ⭐ And the pin's population is stated: 7 own cases, with the 17 reported including 10 from an imported sibling module. That statement is the direct answer to how round 1 slipped — a green pin cited for a claim wider than its cases.

The fixture family is closed, with the census controlled: 12 consumer files, all in plugin-auth, control fired, objectui 0; the family is the 1 + 4 migrated cases and there is no fifth.

⚠️ One PR-body claim measured false — corrected here, not reworked

The body says "spec source is unchanged since round 1." It is not: 11 packages/spec/src files moved via the main merge (one an added test file). ⭐ The PR's own three spec edits are byte-identical, so the conclusion the sentence was defending holds — but the reviewer did the right thing and ran the spec suite rather than inheriting round 1's green: 477 files / 12818 tests, exit 0.

⇒ Not held for it. The sentence lives only in the PR body, this repo squashes from commit messages (#15913), and the claim it supported is independently true. But it is the sixth instance this session of a sentence quantifying over a set the author had only sampled — and note it survived the greppable guard, because "unchanged since round 1" is a temporal claim rather than one of the three phrases the guard names. Worth carrying: the guard catches the phrasing, not the reasoning error behind it.

⭐ The most valuable thing in this review is not about this PR

Four pre-existing server-side readers derive platform authority from the name in ExecutionContext.positions — plugin-sharing/src/sharing-rule-service.ts:254, plugin-approvals/src/approval-service.ts:976, runtime/src/domains/activation-gate.ts:149, plugin-security/src/explain-engine.ts:117. Same species as round 1's blocked escalation, already reachable on main, with ctx.posture already carried at each site for them to read instead. ⇒ Filed as #15981 (p1, security), with the drive-each-site requirement and the ⛔ do-not-verify-by-string-search warning attached.

Gate ledger on this head: full plugin-auth suite 102 / 2142 exit 0 (independently confirmed, closure built first); spec suite 477 / 12818 exit 0; targeted files 17 / 43 / 19 exit 0; check:authorable-surface, check:docs, check:migration-registry, check-role-word (self-test + real), check-nul-bytes all exit 0. Still NOT MEASURED and correctly declared: the remainder of the 153 derived commands (CI runs the farm), browser/dogfood, objectui suites.

Undrafted and auto-merge armed.

CI red on 9a26de3a6 — two failures, and they are not the same kind

Three check runs are red. They split cleanly, and only one of them is this PR's.

1. Type Check · workspace — ⛔ this PR's, and reproduced locally

Run 33978981028, job 101340632005. Turbo's own closing lines: Tasks: 133 successful, 135 total · Failed: @objectstack/plugin-auth#typecheck. The TypeScript Type Check rollup (101342046338) is that job's summary and carries nothing of its own.

Reproduced on this exact head in a checkout of 9a26de3a6, one command per exit code:

command	exit	result
npx tsc --noEmit	0	clean
npx tsc --noEmit -p tsconfig.examples.json	0	clean
npx tsx ../../../scripts/check-test-typecheck.mts --package packages/plugins/plugin-auth --project tsconfig.test.json	1	check:test-typecheck: 1 problem(s)

The gate's own words, one problem, quoted:

src/auth-manager.test.ts: 1 type error(s) carrying a signature the ledger does not record — ARRIVED: TS2554: Expected 1 arguments, but got 2.

Located: packages/plugins/plugin-auth/src/auth-manager.test.ts:3543:30, inside the case this PR adds — "carries an ADR-0057 D4 sys_user_position assignment — the axis the payload was missing". The case overrides the fake engine's find and delegates the non-sys_user_position objects onward:

const inner = engine.find;
engine.find = vi.fn(async (object: string, q?: any) => {
  if (object === 'sys_user_position') { … }
  return inner(object, q);          // ← 3543
}) as any;

makeDataEngine's find is declared vi.fn(async (object: string) => …) — one parameter — so the two-argument delegation is a type error. Every other error tsc -p tsconfig.test.json prints in that file is a signature the debt ledger already records; this is the single ARRIVED one, which is why the gate reports exactly one problem.

⛔ The ledger path is maintainer-only and the gate says so in the same breath — this will be fixed in the test, not admitted to test-typecheck-debt.json.

Why it got through. pnpm --filter @objectstack/plugin-auth test was run and reported 102 files / 2142 tests passed; typecheck is a different turbo task and was not run. Vitest transpiles without checking, so a green suite cannot see this class at all. Recorded as the verification gap it is, and the fix-up is dispatched.

2. Lint & Repo Gates — measured NOT this PR's

Job 101340631783, step 141 Merge-driver wiring gate → pnpm check:merge-driver → node scripts/check-regen-pending.mjs --self-test → ✗ self-test failed -- 1 failure(s) (cases and floor).

Control: the identical step fails on main itself at f7db8f4fd — run 33981169123, job 101346594800, step 141, same name, same closing line. Owned by #15992 (p0, domain:devx, pm:dispatched), with #15990 and #15994 on the same failure; #15992 records the cause as the self-test's gate stubs shelling out to an unpinned pnpm -s that Corepack now resolves to pnpm latest = 12.3.4, which rejects -s. ⚠️ Quoted from #15992, not measured here — measured here is only that the step fails identically on main, and that the same self-test exits 0 locally at origin/main f7db8f4fd on git 2.43.0.

No fix ported: scripts/check-regen-pending.mjs is a single-writer path, and No other open PR may claim the same single-writer path is a required check that is currently green here — carrying the fix would red it and collide with #15992's fix PR. No re-run: an unpinned launcher resolving to a version that rejects a flag is deterministic, not a flake; this PR's one re-run stays unspent.

---

So: the typecheck error is being fixed now; after that this PR is still gated on main going green, not on anything in its own diff. The contract review's round-2 verdict and the two follow-ups it produced (#15981, #15972) are unaffected.

Claim — dev seat, domain:services: taking the Type Check · workspace fix-up

Session session_01XpTx2tbq3pZRYAdoGt6E6Y, branch claude/issue-15136-positions-security-axis, head 9a26de3a617ec59015b91f112f9bebbb9b0252b3. This is the same claim loop that opened this PR (claim comment on #15136: 5552492748) — continuing it, not opening a new one. Re-read the comment timelines on #15136 and this PR rather than trusting the assignee field; the identity is shared.

Scope: exactly one type error, and nothing else. CI Type Check · workspace (run 33978981028, job 101340632005) fails @objectstack/plugin-auth#typecheck on a single ARRIVED problem in src/auth-manager.test.ts — TS2554, a two-argument delegation to a one-parameter fake. ⛔ Not re-opening the round-2 Clause-② design: no edits to auth-manager.ts, platform-admin-gate.ts, the changeset, or this body's argument. ⛔ Nothing added to test-typecheck-debt.json (MAINTAINER-ONLY, ratchets down only). ⛔ No undraft, no merge, no auto-merge.

Lint & Repo Gates is expected to stay red here — it fails on main itself (#15992, dispatched to another seat) and is not mine to chase.

⛔ Correction to my previous comment — section 2 was wrong

My earlier comment said, of this PR's Lint & Repo Gates failure:

2. Lint & Repo Gates — measured NOT this PR's … Job 101340631783, step 141 Merge-driver wiring gate …

Every part of that is false for this PR. I read the merge-driver failure off #15985's job and off main's job, then attributed the same shape to this job without ever fetching its step list. Posting as a new comment rather than an edit, so the wrong claim stays legible next to its correction.

What job 101340631783 actually reports

step 130  Test-source alias gate        completed  FAILURE
step 131–148                            completed  skipped
step 141  Merge-driver wiring gate      completed  SKIPPED   ← never ran on this PR

The job halts at 130. The merge-driver gate — the thing I called this PR's blocker — never executed here. This PR's Lint & Repo Gates red is entirely its own.

The real failure, measured with a base-branch control

node scripts/check-test-source-alias.mjs:

tree	exit	verdict
origin/main f7db8f4fd	0	check-test-source-alias OK — 72 packages with tests scanned; 61 registered as still resolving a workspace dep through dist/; 49 published subpath(s) resolved through every alias table.
this PR head b65fafc81	1	two findings, both in src/session-positions-security-axis.test.ts

The two findings, in the gate's own words:

1. :235 pays import('@objectstack/core') inside a function body — a CLOCKED window. Remedy the gate dictates verbatim: a module-top import '@objectstack/core';.
2. @objectstack/plugin-auth: NEW unaliased artifact import(s) since this entry was measured: @objectstack/formula. Remedy: one anchored entry in the package's vitest.config.* array — ⛔ the gate states the registry is shrink-only, so widening the registry entry is explicitly not the fix.

Ownership, measured rather than inferred: session-positions-security-axis.test.ts is ABSENT from origin/main (git cat-file -e fails), with auth-manager.test.ts as the control that resolves on the same ref. The file is added by this PR, so the gate's redness is this PR's, introduced in round 1.

Credit where it is due, and the pattern

The os-dev on the typecheck fix-up found this on its own, outside its brief, and reported it rather than shipping past it — and it did so against my brief, which told it to expect this job red for an unrelated reason. That instruction is what would have buried the finding. It measured the attribution properly too: reverted its own file in place under a trap, proved the tree byte-identical to 9a26de3a6, re-ran, got the same two findings, restored with git diff HEAD at 0 bytes.

⭐ For the record, because it is the transferable part: this is the same failure mode this PR's round 1 already produced once — a reading true of the population it was taken from (main, #15985, #15993) restated over a wider one (this PR). Round 1's escalation got through because a green pin was cited for a claim its cases did not cover. I then did the mirror image of it in the comment reviewing that very PR. A control is not optional because the conclusion looks obvious.

What is unchanged

The round-2 contract-review verdict stands. Verified by blob equality between the reviewed head 9a26de3a6 and the current head b65fafc81:

auth-manager.ts          4a097c477a409e4971e60c3970f55a38168b8c69  ==  4a097c477…  SAME
platform-admin-gate.ts   409d8e1b26de2bc8b9688a9434a9efdf1ca0ace2  ==  409d8e1b2…  SAME
test-typecheck-debt.json 11f8f4ea43e6cccb8dad9899faaf80deb21731fd  ==  11f8f4ea4…  SAME  (nothing added to the ledger)
auth-manager.test.ts     615bd9cea…  →  15161954d…                       DIFFERS   (the firing control)

The whole delta since review is 1 file, +6/−1: widening the makeDataEngine double to (object: string, _query?: any) plus a comment stating why. The dev chose that over dropping the argument at the delegation, on a measurement rather than an argument — IDataEngine.find takes (objectName, query?, options?) and the only production path reaching this double is resolve-authz-context.ts's tryFind, which always calls ql.find(object, { where, limit, context }). A double declared narrower than its seam is how a double stops expressing the condition it exists to test.

A follow-up fix-up for the alias gate is dispatched. ⛔ This PR is not armed for auto-merge and will not be until both are green and I have re-verified.

Claim — dev seat, domain:services: taking the check:test-source-alias fix-up

Session session_01XpTx2tbq3pZRYAdoGt6E6Y, branch claude/issue-15136-positions-security-axis, head b65fafc81ac1698934ea8e2092957f8556f8b32a. Same claim loop that opened this PR and shipped the Type Check · workspace fix-up (claim comment on #15136: 5552492748; previous fix-up claim on this PR: 5554028115) — continuing it, not opening a new one. The assignee field cannot answer "whose claim is this" under a shared identity, so this is stated in a comment against the timelines of #15136 and this PR, both re-read first.

Scope: check:test-source-alias only, per the correction in comment 5554191202. Two findings, both in src/session-positions-security-axis.test.ts, both remedied as the gate itself dictates: a module-top side-effect import for the clocked-window finding, and one anchored vitest.config alias entry for the new unaliased artifact import. The dynamic import stays where it is; no timeout is widened; the shrink-only registry entry is not widened.

⛔ Not re-opening the round-2 Clause-② design: no edits to auth-manager.ts, platform-admin-gate.ts, auth-manager.test.ts, the changeset, or this body's argument. ⛔ No new PR, no undraft, no merge, no auto-merge arming.

Working in a dedicated worktree at /home/user/objectstack-15948-alias; the shared checkout is untouched.
