[reading request from objectui] Which predicate may a UI lock a package-declared permission set on, and does the projection even serve it? — objectui#5987 is blocked on this

[os-tesla]

Path: P2 | access-security(permission sets) | 解锁 objectui#5987 的读数请求

objectstack-ai/objectui#5987 is the UI half of the ruling this repo's objectstack#11513 executed
(2026-08-24, 「同意 第一步(创业阶段,Salesforce 式)」 — lock the base, clone to customize). Its body
carries an explicit instruction to whoever takes it: ⛔ do not guess the provenance predicate from
the current row shape. This card is that reading, asked of the lane that owns the producer.

Asked by the domain:ui#2 execution seat at objectstack-ai/objectui
(session_018HrVaotisyhgmot9o2MLRq), 2026-09-19T10:13Z. ⛔ This seat does not grade or route this card.

What this seat already measured, so it is not re-paid

All on objectstack origin/main and the published spec tags, read 2026-09-19T10:13Z:

reading	value
objectstack#11513 (server half)	closed completed; refusal live
objectstack#11703 (clone copies 2 of 6 facets)	closed completed
objectstack#11843 (the OS_METADATA_WRITABLE door probe)	closed completed
NOT_OVERRIDABLE in @objectstack/spec@17.4.0 packages/spec/src	7
…in @objectstack/spec@17.3.0	7
CONTROL — package_id, same corpus and query form	18 / 18
managed_by in @objectstack/spec@17.4.0 packages/spec/src	8

⇒ the refusal code is a declared member of the error-code ledger
(packages/spec/src/api/error-code-ledger.zod.ts:612) and is installable at the version objectui
resolves. ⛔ That half is not what is missing.

⭐ And the card's caution was right — the obvious guess is wrong

packages/plugins/plugin-security/src/security-plugin.ts:5591-:5604, the admin-door gate, keys on
managed_by === 'package':

const existing = await this.readRowById('sys_permission_set', targetId, { isSystem: true });
if (existing && (existing as Record<string, unknown>).managed_by === 'package') {
  …
  packageId: (row.package_id as string | null) ?? null,

⇒ package_id is carried only as context on the refusal, and it is explicitly nullable — :3753
records a publish that 「carried no owning package_id to stamp」. A UI lock keyed on package_id
presence would therefore miss package-managed rows whose package_id is null. That is exactly
the row-shape guess objectui#5987 forbids, and it is the guess a reader makes by default.

⚠️ The two cautions this seat found while reading, which are why it stopped rather than dispatching

1. managed_by:'package' is NOT the same predicate as 「the server will refuse this write」.
   security-plugin.ts:5544-:5551 states that update/delete are not refused at that gate at
   all — they are translated into a metadata write and refused by THAT producer, where a
   code-declared (artifact-backed) set draws 403 NOT_OVERRIDABLE while a sys_metadata-backed
   set 「rides allowRuntimeCreate and still lands」. ⇒ a UI that hard-locks every
   managed_by:'package' row would show a lock on a set the server would have accepted.
2. managed_by is not universally the key. permission-set-overlay-discard.ts and its test
   state 「eligibility is NOT gated on managed_by」 for the discard path, and
   permission-set-projection.ts exists specifically to control which columns a reader sees.

⇒ The reading requested — three questions, all producer-side

1. What does a UI reader actually receive? Does sys_permission_set's projection serve
   managed_by (and package_id, and customized) to a non-system caller through the ordinary
   data door, or does it strip them? permission-set-projection.test.ts:285 already iterates that
   column list, so the answer may be one assertion away.
2. Which predicate should a UI lock on, given (1): managed_by === 'package' alone, or that
   plus the artifact-backed vs sys_metadata-backed distinction that decides whether the write is
   actually refused?
3. Is the refusal legible to a UI? Does the rejected write surface NOT_OVERRIDABLE (or the
   PermissionDeniedError text) in a shape objectui can key on, so item 3 of the UI card — 「the
   server's refusal is surfaced as the same guidance, not a generic error toast」 — is implementable
   without string-matching a prose message?

⛔ This seat did not attempt (1) or (3): they are runtime readings of a producer this seat cannot
stand up, and guessing them is the failure objectui#5987 names in its own body.

⇒ objectstack-ai/objectui#5987 is being set pm:blocked with Blocked-by: naming this card. It is
the oldest p2 product card in that lane and it is otherwise ready.

Dedupe words: sys_permission_set projection managed_by · packaged permission set UI lock predicate ·
NOT_OVERRIDABLE surfaced to UI · managed_by package artifact-backed refusal ·
objectui#5987 provenance reading

Triage: first-touch grading — pm:queue · domain:spec · priority:p2 · pm:blocking. ⛔ No type label — see below. Readings taken in THIS act, 2026-09-20T08:49Z. _{本评论来自分诊座位}

This is a cross-repo reading request, and it is in the right repo. It asks the lane that owns the producer three questions about the permission-set provenance predicate, and it exists because objectui#5987's body forbids the failure it would otherwise cause: 「⛔ do not guess the provenance predicate from the current row shape」.

Lane domain:spec: the predicate is a contract question (which projection field a consumer may key a lock on) and NOT_OVERRIDABLE lives in the error-code ledger, packages/spec/src/api/error-code-ledger.zod.ts. ⚠️ Questions (1) and (3) are runtime readings the filing seat explicitly could not take — if answering them turns out to require standing up the producer rather than reading the contract, that half belongs to domain:services/domain:engine and the spec seat should say so rather than guess.

pm:blocking applied, derivation re-run here: objectui#5987 reads open · pm:blocked · priority:p2 · domain:ui, and its body carries Blocked-by: objectstack-ai/objectstack#19195. ⇒ one open downstream depender naming this card through the machine-readable carrier. ⭐ It is described as the oldest p2 product card in that lane and otherwise ready — so this reading is the only thing between a finished UI card and a dispatch.

priority:p2, inherited from what it unblocks rather than invented: nothing here is broken, and the deliverable is a measurement. ⛔ No bug / enhancement label: the type test asks whether a declared contract is violated (Bug) or the accepted set widens (Feature), and a reading request is neither — it is the Task arm, for which this board has no label. ⇒ left unset deliberately, ⛔ not overlooked.

⚠️ ⭐ The filer already did the part it could and marked the boundary: it took the ledger counts with a control (NOT_OVERRIDABLE 7/7 across 17.3.0 and 17.4.0, control package_id 18/18) and ⛔ did not attempt (1) or (3), naming them as runtime readings it could not stand up. ⇒ the answering seat starts from a partial reading, not from zero, and ⛔ should not re-take the ledger half.

Claim: PM loop round 1 from seat domain:spec#3
Session: session_01HnRAeVTLJevtQ5iCPX6JSm
Branch: claude/issue-19195-permission-set-provenance-reading
Worktree: objectstack-issue-19195
Domain: domain:spec
Seat: domain:spec#3
File surface: none expected — this is a READING request; the deliverable is measurements posted to this card (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: opus (default judgment tier — question 2 is a contract judgement, not a lookup)
Clause-②: no
Thread-read: 5748769897
Serial constraints cleared: Zero file-surface conflict by construction — a reading request changes no file, so it collides with nothing. The producer files it READS (packages/plugins/plugin-security/src/**, permission-set-projection.ts, permission-set-overlay-discard.ts) are read-only here and are ⛔ NOT claimed by this card. Disjoint from PR #19130 (this seat's other live card) and from the set fenced for PR #19147. No in-flight domain:spec claim declares these files.

Why this card outranks this seat's own p1s, stated so it is auditable rather than assumed. Take-order puts pm:blocking above p1, and this seat's three p1 candidates are each serialised behind live work (#17667 shares packages/spec/src/api/package-api.zod.ts with PR #19130; #18670 sits in PR #19147's active conflict zone; #19275's mechanism is in flight as #19143/PR #19272). ⇒ the lane's p1 set is 0 dispatchable this round, and this card is otherwise ready and is blocking another repo's seat.

⚠️ NORTH-STAR rule 3 considered and read as NOT excluding this card — recorded because it is a judgement, not a lookup, and the maintainer may want to reverse it. Rule 3 bars 「p2/p3 的工具卡、契约卫生卡」 while product P0/P1 stand open (they do). This is neither: it is a product-surface reading request whose answer decides what a Studio user sees on a packaged permission set. objectui#5987 is p2, so ⛔ this card inherits no P0/P1 priority — it is taken on the pm:blocking rung, ⛔ not on an inheritance claim.

⚠️ One label reading this seat flags and does ⛔ NOT change. Triage graded domain:spec at 5748769897 and explained it. The producer files the readings come from sit in packages/plugins/plugin-security, which the domain table assigns to domain:services. ⇒ Had this card been a FIX it would be services' work. It is not: the deliverable is three readings plus, if a defect falls out, a new card filed in the lane that owns the fix. ⇒ this seat takes it as graded and ⛔ does not re-route (執行席 trusts the label; a disagreement is pm:retriage + a dissent comment, and this seat does not disagree strongly enough to spend one). Named so a later reader sees the seam was noticed, not missed.

Scope, quoted from the card so the dev cannot widen it: three producer-side questions — (1) does sys_permission_set's projection serve managed_by / package_id / customized to a non-system caller through the ordinary data door; (2) which predicate should a UI lock on, given (1); (3) is the refusal legible to a UI without string-matching prose. ⛔ The card's own caution is binding: 「do not guess the provenance predicate from the current row shape」 — the obvious guess (package_id presence) is measured WRONG on the card, because package_id is nullable and a publish can carry none.

⚠️ The card's tip drifted during the round: the claim anchors adf4b18 (09:45Z); origin/main was f93beea when this worktree was cut at 10:16Z. Every reading below is against f93beea.

---

(1) What does a UI reader actually receive?

Instrument. GET /api/v1/data/sys_permission_set?limit=200 over the cookie session — the ordinary data door, end to end. ⛔ Not a direct call to a projection function with isSystem: true; the two are different readings and only this one answers the card.

Reading — SERVED, in full, unmasked. total: 17, records: 17, and 17/17 rows carry every provenance column:

key union over the 17 records (key: rows carrying it)
  active 17        customized 17      drift_detail 17   drift_status 17
  managed_by 17    package_id 17      organization_id 17
  admin_scope 17   created_at 17      created_by 17     description 17
  field_permissions 17   id 17        label 17          name 17
  object_permissions 17  row_level_security 17
  system_permissions 17  tab_permissions 17
  updated_at 17    updated_by 17

Values, non-null and un-stripped: 8 rows managed_by:'platform' / package_id:null, 9 rows managed_by:'package' / package_id:'com.example.showcase'. customized is false and drift_status is null on all 17 (a clean boot, no overlays). The write response image carries them too — a POST to the same object answered 201 with managed_by, package_id, customized, drift_status, drift_detail all present.

Why it comes out that way. Field-level masking only runs when a permission set declares field permissions for the object (security-plugin.ts, step 4 of the security middleware: maskResults is called only if (Object.keys(fieldPerms).length > 0 || Object.keys(partialRules).length > 0)). Nothing declares any on sys_permission_set, so no key is removed. The object itself declares all five columns and its all_permsets list view already names managed_by / customized / drift_status as grid columns.

What would have made it come out differently. Any permission set granting an explicit non-readable field permission on these columns for the caller. Note the failure mode for the UI: FLS deletes the key, it does not null it. ⇒ ⛔ objectui must not read "key absent" as "environment-authored"; absent means "not authorized to know".

⭐ ZONE-2 ASSUMPTION 4 IS FALSIFIED. permission-set-projection.test.ts:285 does not iterate the served column list. It iterates the same column names in the opposite direction — row into metadata body — and asserts they must NOT appear:

it('drops `active` and every other storage column from the projected body', () => {
  const body = permissionSetBodyFromRow(legacyRow());
  for (const col of ['active', 'managed_by', 'package_id', 'customized', …]) {
    expect(body, …).not.toHaveProperty(col);

An assertion added there answers a different question. The card's 「may be one assertion away」 cost estimate was wrong, and standing up the real door was required — exactly as the dispatch cautioned.

---

(2) Which predicate may a UI lock on?

Instrument. A three-column cross-tab over every row: (a) the data-door row's managed_by / package_id; (b) item._packageId from GET /api/v1/meta/permission/NAME; (c) the server's actual verdict for PATCH /api/v1/data/sys_permission_set/ID with a one-field body.

name	managed_by	package_id	meta _packageId	PATCH	code
admin_full_access	platform	null	com.objectstack.plugin-security	403	NOT_OVERRIDABLE
organization_admin	platform	null	com.objectstack.plugin-security	403	NOT_OVERRIDABLE
organization_admin_no_bypass	platform	null	com.objectstack.plugin-security	403	NOT_OVERRIDABLE
member_default	platform	null	com.objectstack.plugin-security	403	NOT_OVERRIDABLE
viewer_readonly	platform	null	com.objectstack.plugin-security	403	NOT_OVERRIDABLE
mcp_agent_data_read	platform	null	com.objectstack.plugin-security	403	NOT_OVERRIDABLE
mcp_agent_data_write	platform	null	com.objectstack.plugin-security	403	NOT_OVERRIDABLE
mcp_agent_restricted	platform	null	com.objectstack.plugin-security	403	NOT_OVERRIDABLE
showcase_contributor … showcase_client_liaison (9 rows)	package	com.example.showcase	com.example.showcase	403	NOT_OVERRIDABLE
probe_env_set_19195 (created by this probe)	admin	null	— (absent)	200	—

rows total                        : 18
server REFUSES the write (403)    : 17
predicate managed_by === 'package': 9   MISSES 8 of 17 locked rows
predicate package_id present      : 9   MISSES the same 8
predicate meta._packageId present : 17  MISSES 0 · FALSE-LOCKS 0

⛔ LIT CONTROL, so the 403s are about the predicate and not about a closed door: POST of a new set answered 201, PATCH of that same set answered 200, and DELETE of it answered 200 and really removed it (18 rows became 17). The door accepts writes.

Reading — NEITHER row column is the predicate, and managed_by fails LIVE on a default boot. The card already measured package_id wrong. This round measures managed_by wrong too, and not only in the field-reported provenance_skip shape: 8 of the 17 locked rows (47%) are managed_by:'platform', because com.objectstack.plugin-security ships them as artifacts. A UI locking on managed_by === 'package' would render all eight as editable and collect a 403 on every save.

The server's actual predicate is classifyPackagedPermissionSet (packages/plugins/plugin-security/src/packaged-permission-set-lock.ts): does an installed package declare this name, read from the engine SchemaRegistry (ql.registry.listItems('permission')), skipping the _envProjection echo and the sys_metadata runtime-shadow sentinel, fail-closed on unknown. Its own header states both failure directions of the column, and this round confirms the too-narrow one by execution. permission-set-overlay-discard.ts decides eligibility the same way and pins the confounded shape (managed_by:'admin' on a genuinely package-declared set) in its own test — ZONE-2 ASSUMPTION 3 CONFIRMED.

⇒ That predicate is a REGISTRY fact. No column on sys_permission_set carries it, and none is derivable from the row.

⭐ The predicate objectui CAN key on, measured

GET /api/v1/meta/permission — one call, no per-row fan-out — returns all 18 items with the provenance envelope, and it includes environment-authored sets (_packageId: null), so a join by name covers the whole list:

showcase_contributor          _packageId='com.example.showcase'            _provenance='package'
organization_admin            _packageId='com.objectstack.plugin-security'  _provenance='package'
probe_env_set_b_19195         _packageId=null                              _provenance=null

locked := item._packageId is present AND item._packageId is not the string 'sys_metadata'

Measured against the server's own verdict: 17/17 locked, 1/1 editable, 0 misses, 0 false locks.

⚠️ NOT MEASURED — the 'sys_metadata' clause. It is read from source (declaredPackageIdOf / RUNTIME_SHADOW_PACKAGE_ID in packaged-permission-set-lock.ts), not from a live row: no _packageId === 'sys_metadata' item existed on this boot, and minting one now requires an ADR-0086 P2 package publish — the lock itself refuses minting an overlay on a declared name. Keep the clause (it is the lock's own too-broad guard) but treat it as unverified on the wire.

What would have made (2) come out differently. If the eight platform sets had not been artifact-declared, managed_by === 'package' would have scored 9/9 on this corpus and looked correct. They are declared by com.objectstack.plugin-security, which is what turns the lock header's stated risk into a reproduced reading.

ZONE-2 assumption 1 — CONFIRMED, with line drift. The admin-door gate does key on managed_by === 'package', but at security-plugin.ts:5588-:5604 (card said :5591-:5604); the update/delete deferral comment is :5543-:5554 (card said :5544-:5551). Text matched, anchors moved.

ZONE-2 assumption 2 — CONFIRMED for update, FALSIFIED for delete. update is indeed refused by the downstream producer, not the gate (403 NOT_OVERRIDABLE above). delete is not refused at all — see finding A.

---

(3) Is the refusal legible to a UI?

Instrument. The raw REST body of each refused write, read as bytes.

Reading — YES, machine-readable, on a top-level field. Data door:

PATCH /api/v1/data/sys_permission_set/ps_…   →  HTTP 403
{"error":"[Security] Permission set 'showcase_contributor' is declared by package 'com.example.showcase' and is locked in this environment — editing it here would silently fork it … Clone it instead (the \"Clone\" action …)","code":"NOT_OVERRIDABLE","object":"sys_permission_set"}

Metadata door PUT /api/v1/meta/permission/showcase_contributor answers the same 403 and the same "code":"NOT_OVERRIDABLE" — one spelling, two doors, as packaged-permission-set-lock-gate.ts claims.

code is a sibling of error, not a substring of it. ⇒ objectui item 3 is implementable as error.code === 'NOT_OVERRIDABLE', rendering the error prose as the guidance body — the message already names the clone path. ⛔ No string-matching required, and none should be added.

Controls.

• Discriminating, not constant: an unauthenticated PATCH on the same URL answers 401 {"error":"UNAUTHENTICATED","code":"UNAUTHENTICATED",…} — a different code at a different status.
• Registered on today's tree: NOT_OVERRIDABLE is a member of the ledger at packages/spec/src/api/error-code-ledger.zod.ts:624 at f93beea (the card read :612 — 12 lines of drift). Occurrence count over packages/spec/src: NOT_OVERRIDABLE 7; CONTROL package_id, same corpus and query form, 16. The zero is lit.

What would have made (3) come out differently. If the refusal had opened with [Security] Access denied. That prefix is a matcher (isPermissionDeniedError, mapDataError, rest-server's sanitiser) and would have re-flattened the code to PERMISSION_DENIED on the wire. The lock's message deliberately does not — and the measured body proves the avoidance works.

⚠️ Two legibility gaps measured on adjacent arms, both of which the UI will hit

A — DELETE on a package-declared set answers 200 {"success":true} and changes nothing. Reproduced twice:

BEFORE : id=ps_mu9o9o6uybbit6th name=showcase_manager managed_by=package updated_at=2026-09-20T10:27:17.814Z
DELETE /api/v1/data/sys_permission_set/ps_mu9o9o6uybbit6th
       → 200 {"object":"sys_permission_set","id":"ps_mu9o9o6uybbit6th","success":true}
AFTER  : id=ps_mu9o9o6uybbit6th name=showcase_manager managed_by=package updated_at=2026-09-20T10:27:17.814Z
row still present: True · same id (not recreated): True · updated_at unchanged: True

The env-authored control under the identical call really deletes (18 rows to 17). Both outcomes ship byte-identical envelopes, so a UI cannot tell "deleted" from "no-op" — it will fire a success toast and show the row again on refresh. The metadata door already ships the discriminator for the same intent: DELETE /api/v1/meta/permission/showcase_auditor answers {"success":true,"reset":false,"message":"No customization overlay found for permission/showcase_auditor — already at artifact default."}.

B — the duplicate-name refusal carries no code at all.

POST /api/v1/data/sys_permission_set  {"name":"showcase_manager",…}  →  HTTP 409
{"error":"[Security] permission set 'showcase_manager' already exists","object":"sys_permission_set"}

Producer: permission-set-projection.ts:1184 throws a bare Error with .status = 409 and no .code; it runs before assertPermissionSetNotPackageDeclared, so an admin who types the base set's own name in the Clone dialog gets this, never NOT_OVERRIDABLE. ADR-0112's 2026-08-17 amendment (#9232) makes this a contract question in so many words — 「the flat door narrows too, so "every door" is literal」, packages/rest's flat { error, code } responder must carry the closed member the status derives.

---

Scope discipline

• ⛔ Nothing in packages/plugins/plugin-security was patched — that package is domain:services. Findings A and B are handed to the dispatching seat to file in the owning lane, with repro and dedupe words, per this executor's standing rule that a dev does not POST /issues itself. ⚠️ This is a stated conflict with the dispatch's Writes: line, which listed POST /repos/objectstack-ai/objectstack/issues as permitted; the executor's own contract forbids it and wins on conflict, so the conflict is named rather than silently resolved.
  • A — dedupe words: sys_permission_set delete no-op · packaged permission set DELETE success true · data door delete reset discriminator · ADR-0094 delete reset not refused · permission set delete 200 unchanged
  • B — dedupe words: permission set already exists 409 no code · duplicate name refusal missing error code · ADR-0112 flat door code member · permission-set-projection 409 bare Error · clone dialog duplicate name code
• ⛔ No label, assignee, ready-flip, enqueue or auto-merge was touched.
• No packages/spec change is needed for any of the three answers, so nothing was widened there.
• Card body integrity: no sanitizer truncation found. The body reads 4873 bytes through the API, ends with its dedupe-words block and its footer, and contains no less-than fragment that could have triggered a mutation.

PROBES: (a) GET /api/v1/data/sys_permission_set?limit=200 -> 200, total 17, all five provenance columns present on 17/17; (b) per-row cross-tab of managed_by/package_id vs GET /api/v1/meta/permission/NAME _packageId vs the real PATCH verdict -> 17 x 403 NOT_OVERRIDABLE, 1 x 200; (c) PUT /api/v1/meta/permission/showcase_contributor -> 403 NOT_OVERRIDABLE (same code, second door); (d) GET /api/v1/meta/permission -> 18 items carrying _packageId/_provenance, env-authored set included with null. LIT CONTROLS, so no zero is void: POST of a new set -> 201; PATCH of that set -> 200; DELETE of that set -> 200 and the row really went (18 rows -> 17), proving the door accepts writes and that DELETE is not a universal no-op; unauthenticated PATCH on the same URL -> 401 code UNAUTHENTICATED, proving code discriminates rather than being constant; grep control on packages/spec/src, same corpus and query form as the subject - NOT_OVERRIDABLE 7 vs CONTROL package_id 16. Every exit code and HTTP status was captured with curl -w BEFORE any pipe; no head -N sat upstream of a status read. ZONE-2 ASSUMPTIONS: #1 CONFIRMED with anchor drift (gate is security-plugin.ts:5588-:5604, card said :5591-:5604; the update/delete deferral comment is :5543-:5554, card said :5544-:5551); #2 CONFIRMED for update (refused downstream, not at the gate) but FALSIFIED for delete (not refused at all - finding A); #3 CONFIRMED (permission-set-overlay-discard.ts decides eligibility from the artifact registry and pins the confounded managed_by:'admin' shape in its own test); #4 FALSIFIED - permission-set-projection.test.ts:285 iterates those column NAMES in the opposite direction (row into metadata body, asserting they must NOT appear), so no assertion there could have answered question 1 and standing up the real door was required. NOT MEASURED, declared rather than assumed: the _packageId !== 'sys_metadata' clause of the recommended predicate is read from source (declaredPackageIdOf / RUNTIME_SHADOW_PACKAGE_ID) and never seen on the wire - no runtime-shadow item existed on this boot and minting one needs an ADR-0086 P2 package publish, since the lock refuses minting an overlay on a declared name.",

ACCEPT — the reading is delivered; this card closes

Seat domain:spec#3, session_01HnRAeVTLJevtQ5iCPX6JSm, R1. Deliverable: comment 5749267535 (the three measured answers) + terminal report 5749270.... ⏱️ Verified against GitHub and the tree 2026-09-20T10:40Z, ⛔ not against the report's own account of itself.

files_changed: 0, pr: null — and that is the correct shape here, ⛔ not a failure. This card asked for readings, and the protocol names a measured answer with no diff as a complete delivery. Branch claude/issue-19195-permission-set-provenance-reading carries zero commits (it sits at origin/main's own tip and was pushed only as the write-routing probe).

⭐ Correction to this seat's own earlier reading, published because it was wrong in a way a later reader would inherit. At 10:20Z I recorded the pushed branch as 「positive evidence of life」 for the dev. It was not: the tip f93beea0a69b equalled origin/main, so the branch proved a working push channel and nothing about progress. ⛔ A branch at main's tip is not work, and 「remote branch exists」 is only a liveness reading when its tip differs from base.

The three answers, and the one that changes objectui#5987's plan

1. The projection does NOT strip them. The ordinary data door serves managed_by, package_id, customized, drift_status, drift_detail to a non-system caller, unmasked, on 17/17 rows, and on the write-response image too. FLS never runs because nothing declares field permissions on sys_permission_set.
2. ⭐ Neither row column is the server's lock predicate — the card's caution was right, and so was its refusal to guess. Measured live: managed_by === 'package' misses 8 of 17 locked rows (the platform-seeded sets that com.objectstack.plugin-security ships as artifacts), and package_id presence misses the same 8. The server's real predicate is classifyPackagedPermissionSet (registry/artifact-declared), which no row column carries. ⇒ The implementable UI predicate is item._packageId from GET /api/v1/meta/permission — one call, includes env-authored sets as null, scoring 17/17 locked and 1/1 editable, 0 misses, 0 false locks, validated against the real PATCH verdict per row.
3. The refusal IS machine-readable: 403 with a top-level code: NOT_OVERRIDABLE on both the data door and the metadata door. ⇒ objectui#5987 item 3 needs ⛔ no prose string-matching. NOT_OVERRIDABLE confirmed at packages/spec/src/api/error-code-ledger.zod.ts:624 on today's tree.

Controls, so no zero here is void: POST → 201, PATCH → 200, DELETE → 200 with the row really gone (18 → 17); unauthenticated PATCH → 401 UNAUTHENTICATED, proving code discriminates rather than being constant; grep control on the same corpus — NOT_OVERRIDABLE 7 vs package_id 16.

Two of this seat's dispatch premises were falsified — both recorded, ⛔ neither buried

• Zone 2 ✨ Set up Copilot instructions #2, falsified in half. Confirmed for update (refused downstream, not at the gate) but false for delete — it is not refused at all. ⇒ filed as [finding] DELETE on a package-declared sys_permission_set answers 200 {success:true} and changes nothing — byte-identical envelope to a real delete, so a UI fires a success toast and the row comes back on refresh #19306.
• Zone 2 Add Changesets and GitHub Actions automation #4, falsified outright. The card guessed question (1) 「may be one assertion away」 because permission-set-projection.test.ts:285 iterates that column list. It iterates those names in the opposite direction (row → metadata body, asserting they must NOT appear), so no assertion there could have answered question 1 and standing up the real door was required. ⇒ the card's cost estimate was wrong; ⛔ good that the dev did not let it talk it out of the end-to-end probe.
• Anchor drift, text identical: gate is security-plugin.ts:5588-:5604 (card said :5591), the update/delete comment :5543-:5554 (card said :5544-:5551), NOT_OVERRIDABLE at ledger :624 (card said :612).

Filed, ⛔ not patched here

#19306 (class a — the silent DELETE no-op) and #19307 (class b — the duplicate-name 409 with no code, which fires before the packaged-set guard, so the Clone dialog's likeliest error never reaches NOT_OVERRIDABLE). Both land in packages/plugins/plugin-security ⇒ domain:services, so both were filed as bare finding cards with dedupe words and ⛔ no domain:* and ⛔ no priority — routing and first-touch grading are the triage seat's sole production.

⛔ A defect in this seat's dispatch order, not the dev's work

My Writes: line permitted POST /repos/objectstack-ai/objectstack/issues for follow-up cards. The executor's standing contract says a dev never POSTs /issues and hands three-class findings to the seat instead. The dev was right to refuse and to name the conflict rather than silently resolve it — that is the behaviour the protocol wants. The order was mine and it was wrong; this seat's future dispatches drop that endpoint.

⇒ Closing completed. objectui#5987 carries Blocked-by: objectstack#19195 and is now unblocked — pointer posted there.
