plugin-auth: register the app:seeded backfill handler from the arming kernel:ready handler, so the guard #22312 added is structural and check:settings-bind-window can see it (child of #22316)

This card carries the plugin-auth half of #22316: one structural move in packages/plugins/plugin-auth/src/auth-plugin.ts. The parent keeps the gate half, PR #22325 (scripts/check-settings-bind-window.mjs), which lands after this one.

Filing gate: an in-flight derivative sub-issue of #22316 (domain:devx, priority:p3 inherited), filed and owned by the claiming seat (domain:devx seat 1, #6023, session_0115N1oNnQS5WqofZ2DzaT3q). Reader: that seat, which dispatches it directly.

Why

PR fix(check:settings-bind-window): judge the handlers of every hook fired before the bind, and follow promise continuations #22325 widens the gate to every Phase-1/2 hook and follows promise continuations. Measured by its developer (os-dev-report on tooling(check:settings-bind-window): the gate scores a plugin by its init/start bodies and kernel:ready handlers only, so a settings read from another Phase-2 hook (app:seeded) passed green while the showcase boot logged a Pre-bind READ #22316): on main with PR fix(plugin-auth): a seeded boot no longer reads the auth settings before the settings engine binds (#22257) #22312 merged, the gate reads RED at auth-plugin.ts [app:seeded-hook-from-start].
The cause: PR fix(plugin-auth): a seeded boot no longer reads the auth settings before the settings engine binds (#22257) #22312 made the early app:seeded backfill calls no-ops through a runtime flag. At origin/main 28bff18d0c, let backfillArmed = false (:1295) is set inside the kernel:ready handler (:1353). But ctx.hook('app:seeded', () => runBackfill('app:seeded')) (:1364) is registered unconditionally from start(). A static walk cannot see a runtime flag.
Measured by the same developer in a throwaway worktree on the merged tree: registering the app:seeded handler from inside the arming kernel:ready handler makes the widened gate read GREEN, with no ledger entry.

Done when

The app:seeded handler is registered from inside the arming kernel:ready handler, so it cannot run before the bind by construction.
Runtime behaviour is unchanged. Every pin PR fix(plugin-auth): a seeded boot no longer reads the auth settings before the settings engine binds (#22257) #22312 added passes unchanged (auth-settings-ordering.pin.test.ts, auth-settings-seeded-boot.pin.test.ts), along with the package's suite. The developer judges whether backfillArmed is still needed and removes it only if it is provably dead.
PR fix(check:settings-bind-window): judge the handlers of every hook fired before the bind, and follow promise continuations #22325's widened check:settings-bind-window reads GREEN on a tree carrying this change.
One patch changeset for @objectstack/plugin-auth. ⛔ No behaviour, option or public-surface change.

The decision behind this split is recorded on #22316.

PR #22325's widened gate (head 96d46ea02d) reads GREEN over this tree with no ledger entry, RED on unmodified origin/main 28bff18d0c (control), and RED again when the ablation moves the registration back. backfillArmed is KEPT, not dead: the default-org-created trigger (runBackfillOnDefaultOrg) still reaches runBackfill before arming from the objectql middleware during Phase 2 and from the bootstrap's own kernel:ready hook, which runs ahead of the arming one. Zone-2 assumptions MEASURED on real ObjectKernel and LiteKernel with a throwaway A/B probe (base vs fix, pass stubbed undecided): (1) holds — hook() pushes into the kernel's hooks map and trigger() reads it at dispatch time over the live array; a post-ready emit runs the pass in both shapes (1 then 2 passes); (2) holds — no emit the flag let through is lost (P1, P2 in-flight-with-blocker-before-slot, P5 in-budget awaited: identical). Two scheduling non-identities were measured in synthetic compositions, both from appending at ready time: P3 an emit still in flight across arming whose base slot was a pre-arming no-op now reaches the appended handler (base 1 pass, fix 2; the extra call is post-bind and stops at backfillDecided once decided); P4 for a post-ready emit the auth handler now runs after a start()-registered subscriber of a plugin that starts after auth (base auth,other; fix other,auth). Neither has an in-repo instance on os serve: the only start()-registered app:seeded subscriber besides auth is platform-objects, composed before AuthPlugin (serve.ts 3945 vs 4102); plugin-security and the CLI announcer subscribe in init(). No structural shape is truly identical (the kernel has no insert-at-position; a start()-time registration is what the gate rejects), so the ruling's shape is the smallest structural one. One existing unit test that pinned the start()-time registration now pins the new structure; both #22312 pins pass unchanged.",

ACCEPT — PR #22333 (head `9c8ed2b62e`) · 2026-10-08T18:57Z

Reviewed by domain:devx seat 1 · session_0115N1oNnQS5WqofZ2DzaT3q, against GitHub and origin/main, not the report.

Checklist: draft, base main, first line Fixes #22328. A full body scan finds that one closing keyword and no other (the body also cites #22316, #22325, #22312, #11045 and #2996, with no verb beside any of them). The PR changes 3 files, +38/−10: auth-plugin.ts, auth-plugin.test.ts and one changeset. That is the claim's file surface. @objectstack/plugin-auth is published (no private), and it carries a patch changeset. Not governed (check-governed-merges --pr 22333: 0 of 3 paths). No os-regen path is touched. Clause-②: no, and the path limb is clean (no packages/spec).

Code, read by the seat at the PR head:

The app:seeded registration now sits inside the arming kernel:ready handler, between backfillArmed = true and return runBackfill('kernel:ready'), in one synchronous step. This is the shape ruled in 6065407005.
The reason for keeping backfillArmed holds on the head:
- runEnsure is registered on kernel:ready at :1240, ahead of the arming handler at :1353.
- The objectql middleware at :1252 also calls runEnsure, and both reach runBackfillOnDefaultOrg (:1232) before arming.
- So the flag is still the only guard on that path. The PR's Acceptance notes record that this middleware path is outside PR fix(check:settings-bind-window): judge the handlers of every hook fired before the bind, and follow promise continuations #22325's gate population.
OS_SKIP_MEMBERSHIP_BACKFILL=1 still gates the whole block, so no app:seeded handler is registered at all in that case.

Test: the start()-time pin became a pin of the new structure: 0 app:seeded handlers after start(), and exactly 1 after kernel:ready. That assertion fails on the old structure. The two #22312 pins are unchanged.

Changeset sentences checked against the diff:

"Its handler used to be registered in start() and kept from acting early by a runtime flag".
"The handler is now registered by that kernel:ready hook, at the moment it arms the backfill, so it does not exist before the settings engine binds."
"An app:seeded that fires before the backfill is armed still does nothing, and one that fires after it still re-runs the pass."
"OS_SKIP_MEMBERSHIP_BACKFILL=1 still registers no app:seeded handler at all."

All four are true on the head. The third holds on every in-repo composition. The report's P3 (an emit still in flight across arming, behind a slower subscriber placed after the auth slot) is a synthetic composition with no in-repo instance. Its extra call runs after the bind and stops at backfillDecided.

Gate proof: the dev reports, with the commands in the PR body, that PR #22325's widened script goes red on 28bff18d0c, is green on this head with 0 ledgered entries, and goes red again under the ablation. The seat confirmed the red half on its own: PR #22325's Lint & Repo Gates at 96d46ea02d (job 113445078033) fails with only that gate, on the same [app:seeded-hook-from-start] signature at auth-plugin.ts:1591. The green half becomes the seat's own reading when PR #22325 re-runs on a main that carries this PR.

CI, read by the seat at 9c8ed2b62e: all 34 check runs are complete, 31 of them success, including Lint & Repo Gates and TypeScript Type Check. The 3 skips are all on the roster (check-expected-skips --pr 22333: OK).

Deviations accepted: two scheduling non-identities, P3 and P4. Both come from appending at ready time, and neither drops an emit. On os serve, PlatformObjectsPlugin is composed before AuthPlugin, so no subscriber sits after the auth slot. Cloud-held compositions are NOT MEASURED, as the PR body says. check:dual-build-cjs-loads was NOT MEASURED locally. CI runs it inside Build Core, which is success on this head.

Landing: ready + auto-merge now. PR #22325 then merges main and carries Fixes #22316.
