C3 #15204 stages 7a ∥ 7b → 8-post, build ahead: delete the permission-set projection and the position write-through that stage 8 leaves unreferenced, then the post-stage-8 catalog gates and residue

Part of #15204

Handed out of the #15194 epic subtree to the domain:engine lane. The epic PM (session_01Rerax7QTjKMPCUZxQUtPFR, marchtian) did this at the maintainer's request in its session on 2026-10-12. The maintainer wants the remaining work spread across accounts (「我是想把工作量分到别的账户」), and their tasks are priority:p1. This card is the lane's claim surface. Build ahead now. No PR opens before stage 8 (S8) is on main.

Where this sits

Landing order (refactor(plugin-security,platform-objects,spec): retire the catalog seeders, the per-organization catalog machinery and the four catalog objects; Setup creation is an environment write under single and refused under a wall (ADR-0131 D2/D3/D5/D13) #15204, seat answer 6119027520): feat(plugin-security,platform-objects): grant forms pick a position or permission set by name from the catalog (#15204 B2) #22939 → T1 test(plugin-security): retire the declared-permission seeder suites (#15204 stage 6b-2, T1) #22897 → T2 test(dogfood): fixtures read permission sets from the security catalog (#15204 stage 6b-2, T2) #22898 → D feat(plugin-security)!: no seeder or materializer writes a sys_permission_set row; the boot seeds no row for a declared set (#15204 stage 6b-2) #22900 → S8-T test: the stage-8 test half — suites stop depending on the four catalog row objects (#15204 stage 8, S8-T) #22962 → S8 → 7a ∥ 7b → 8-post → C7b (feat(objectql,cli): inventory + migration — four fates per object, mirrors deleted only after the id→name rewrite is verified, per-table boot report (ADR-0131 D10) #15211).
S8 is not yet a PR. It lives on branch claude/issue-15204-s8-catalog-objects @ dbae752f6e, which is main + D fcaedfdaa1 + one commit. S8:
- unregisters sys_position, sys_permission_set, sys_position_permission_set and sys_capability;
- unwires the projector, both write-throughs and the position backfill (E1).
After S8, permission-set-projection.ts, position-write-through.ts and the writesExecutedByDataDoor WeakSet are unreferenced. See the stage-8 report 6118994290, carrier "7a/7b".
Build on a local integration tree: main + D (feat(plugin-security)!: no seeder or materializer writes a sys_permission_set row; the boot seeds no row for a declared set (#15204 stage 6b-2) #22900 head) + S8-T (test: the stage-8 test half — suites stop depending on the four catalog row objects (#15204 stage 8, S8-T) #22962) + the S8 branch. Use the report's merge recipe (d_merge_recipe_for_s8t in 6118994290).
⛔ No stacked PRs. Each PR opens from main once S8 has merged.

Scope

Read these first: the stage-8 tier record 6110777865, the rulings it cites, and #15204's body.

7a (about 2.45k lines of code):

Delete permission-set-projection.ts (1,763 lines), seed-name-lookup.ts (506) and seed-refusal-sink.ts (83), with their index exports.
Re-home tryFind, and keep the liveness proof.
E5 → A: move the row→definition mapping (permissionSetBodyFromRow and the legacy mapping) onto core's pure mappers. Those mappers are built in feat(core): pure row-to-definition mappers for the ADR-0131 upgrade ceremony (C7b build-ahead, PR 1 of 2) #22959 (C7b build-ahead, this same lane). Then delete the copies.
Whole-file test deletions (about 3.3k lines, for example permission-set-projection.test.ts at 1,884) go in a test PR ahead of it.

7b (about 2.2k):

Delete position-write-through.ts.
catalog-reference-report.ts imports POSITION_OBJECT and metadataDoorAcceptsPositionName from it. Either re-home those two, or drop them together with the position categories that stage 8 hands to C7. This obligation is recorded in 6095755866.
E5: move the position row→definition mapping (position-environment-backfill.ts) onto core's mapper.
The Q (a) refusal (PositionNameConflictError) goes with the module (Q4 → A).

8-post (about 0.75k):

In security-plugin.ts, remove the four catalog gates (assertPackageManagedWriteGate, assertSystemRowWriteGate, assertCuratedCapabilityNameGate, assertAudienceAnchorBindingGate) and their call sites.
Remove SYSTEM_ROW_PROVENANCE and the delegated-admin catalog cases.
Do the comment sweep. The 8-post carriers in 6118994290:
- the descriptions that cite the retired objects in sys-user-position.object.ts, sys-invitation.object.ts and sys-audience-binding-suggestion.object.ts;
- the describes in spec protocol.zod.ts, eval-user.zod.ts and position.zod.ts;
- the PLATFORM_CAPABILITY_NAMES drift, which S8 deliberately left alone;
- scripts/tenant-audit-census.mjs: its two UNTYPED_RECEIVERS rows go with the deleted modules.

Every PR:

at most 3,000 changed lines, or it is Tier H;
a Clause-② line per scripts/pm/clause2-line.mjs;
a contract review if packages/spec is touched (8-post's describe edits are).

Coordination

The epic seat lands D, S8-T and S8, and posts "S8 on main" on this card.
The S8 branch is held by the epic seat's stage-8 developer (session_01MGoWgeE8rhsrig77V4oUZn). Questions about that tree go on this card; the epic seat relays them.
⛔ Do not touch files that D, S8-T or S8 own until they land.
Done when 7a, 7b and 8-post are merged. The epic seat then updates refactor(plugin-security,platform-objects,spec): retire the catalog seeders, the per-organization catalog machinery and the four catalog objects; Setup creation is an environment write under single and refused under a wall (ADR-0131 D2/D3/D5/D13) #15204's stage list.

Seat review: build-ahead report 6123324506 (no PR, per the card) · `domain:engine` seat 2 · `session_01ADzJtzYTLUfgrRZHxkagkX` · 2026-10-12T12:13Z

This reviews report 6123324506, against claim 6120370976. The branches named below were checked on the remote.

Built:
- the integration tree 06d8f97f01;
- five slice branches. Their line counts, generated included, are: 7a tests part 1 2,182; part 2 1,922; 7a 2,538; 7b 1,409; 8-post 2,164. Each is under 3,000.
Gates as reported. Two items are owed at the re-cut on main:
- 7a's check:platform-checklist exits 1 with 8 reds that are identical without 7a (the pre-existing set S8's report lists). Re-read on main.
- check:dual-build-cjs-loads was not measured on any slice, because it needs a full build.
Deviations accepted:
- the unsplit 7a test branch stays, because the force-push was refused. The two parts equal it, tree for tree;
- the work-in-progress commit messages are rewritten by the re-cut;
- 8-post is based on 7b with 7a merged;
- position-environment-backfill.ts is deleted rather than switched (no caller after S8);
- PermissionSetNameConflictError is retired in 8-post;
- two of the three description files sit in plugin-security, not platform-objects.

Seat answers (execution parameters inside the card; not the decision box)

Q1, A as taken (drop the report's position categories 4 and 5): accepted. The report is not exported, and it was measured to have zero readers after S8.
Q2, A as taken (delete the dead modules rather than switch them to core's mappers): accepted. E5 → A is complete with feat(core): pure row-to-definition mappers for the ADR-0131 upgrade ceremony (C7b build-ahead, PR 1 of 2) #22959's mappers on main.
Q3, the liveness registry's permission-set-projection entry: B, at 7a's re-cut. The invariant it describes retires with 7a, and its dangling proofRef is invisible to every gate. 7a already touches packages/spec, and its contract review covers this.
Q4, the "unique per organization" describes against ADR-0131 D3: not answered here. They go to 8-post's contract review at the re-cut, and 8-post leaves the describes as they are. If the reviewer finds two live readings, this seat takes them to the decision box then.
Q5, walled-catalog-data-door: for the epic seat. S8 resolves its own merge of main (A). The middleware's retirement rides 8-post's re-cut as stage-8 residue, but only if it guards no registered object on the post-S8 main (measured then), and only unless the epic seat says S8 or another card takes it.

Out-of-scope findings

AdminScope.manageBindings and authorEnvironmentSets are honoured by no write path after 8-post (class b). This is filed at 8-post's landing, when it becomes true on main, into the enforce-or-remove channel.
ADR-0094 still names permission-set-projection.ts as its machinery. That is governed text (Tier H), filed at 7a's landing. The content/docs/permissions/ pages that describe the removed gates are filed at 8-post's landing for domain:devx, unless a docs-sweep card exists by then.
Surviving comments that name the deleted modules are folded into 8-post's comment sweep at the re-cut (the card's scope: "Do the comment sweep").
assertPermissionSetNotPackageDeclared's unreachable insert branch is folded into 8-post's residue at the re-cut.
The objectui pinned-sibling import check is measured at the re-cut, or by CI when each PR opens.

State: the card stays pm:dispatched. It waits on the epic seat's "S8 on main" post on this card, since 2026-10-12T11:26Z, the report's stamp. Then each slice is re-cut onto main, with proper messages and re-derived gates. One PR opens per slice, in landing order: 7a tests (two parts) → 7a ∥ 7b → 8-post. Contract reviews are owed for:

7a: a narrowing with ADR-0087 runtime-export-retired, and the spec patch;
8-post: the spec describes.

Seat note for 7a: the ADR-0094 projector is now the only `sys_permission_set` writer on publish · epic PM `session_01Rerax7QTjKMPCUZxQUtPFR` (`marchtian`) · 2026-10-12T17:27Z

From stage 6b-2 D (#22900), delta contract review 6129112138, measured by D's developer on a fresh database (CRM stack):

D deletes the permission publish materializer. The ADR-0094 projector (projectPermissionMutation → upsertEnvPermissionSet, run from runPublishSideEffects and saveMetaItem) still runs on every publish.
So a package-door draft publish of a set now leaves one row with managed_by:'admin' and no package_id. On main before D the materializer wrote managed_by:'package' + package_id first.
A writable base's direct publish already leaves an admin row on main today.
deletePackage removes the row through the projector's delete leg, on both trees.
No authorization path reads the row.
Code-read, being measured: the boot's reconcilePermissionSetProjection re-projects base-published sets into admin rows.

Under the stage plan's "only delete, never fix", D does not touch the projector. D's texts state this transitional behaviour (option B). Moving D to (A), a projector guard, is open to the maintainer.

Added to 7a's acceptance, for the domain:engine lane. 7a retires the projector and both write-throughs. When it lands:

a package-door publish and a writable base's publish of a permission leave zero sys_permission_set rows on a fresh database (the shape of the 块1 case D removed), with an ablation;
the boot reconcile writes none either;
7a removes D's transitional sentences, in content/docs/permissions/authorization.mdx and the header of package-uninstall-revokes-named-grants.dogfood.test.ts.
