+  - "Disabled-check inlined in POST rather than extracted into a shared helper with the scheduler check (per plan D-01, deferred to 13-03)"

+# Phase 13 Plan 02: Scheduler & Admin Toggle (admin surface) Summary
+
+**PAX8 registered as a toggleable /admin/integrations row and POST /api/pax8/sync now returns 403 while PAX8 is disabled via the operator toggle.**
+
+## Performance
+
+- **Duration:** 6 min
+- **Started:** 2026-07-11T13:XX:XXZ
+- **Completed:** 2026-07-11T13:XX:XXZ
+- **Tasks:** 2 completed
+- **Files modified:** 2
+
+## Accomplishments
+- PAX8 now appears as a row (key `pax8`, name `PAX8`, category `finance`) in `checkIntegrationHealth()` output, making it toggleable on `/admin/integrations` and flowing through the existing `applyDisableOverlay` with zero changes to that overlay logic.
+- `POST /api/pax8/sync` now returns HTTP 403 as its very first action when `integration_settings.key='pax8'` has `disabled=true`, closing the manual-trigger "side door" per D-02 — no other behavior changed.
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Register PAX8 as an integration-health row** - `3c114ae` (feat)
+2. **Task 2: Gate POST /api/pax8/sync on the disabled toggle (403)** - `fdc9919` (feat)
+
+_Note: No TDD tasks in this plan; single commit per task._
+
+## Files Created/Modified
+- `lib/services/integration-health.ts` - Added `Promise.resolve(checkConfigOnly('pax8', 'PAX8', 'finance', ['PAX8_CLIENT_ID', 'PAX8_CLIENT_SECRET']))` to the `Promise.all` array inside `checkIntegrationHealth()`, immediately after the `appgate` entry.
+- `app/api/pax8/sync/route.ts` - Inserted a disabled-check as the first statement of `POST`: queries `SELECT disabled FROM integration_settings WHERE key = 'pax8'` and returns 403 with `{ error: 'PAX8 is disabled', message: '...' }` when `rows[0]?.disabled === true`. `GET` unchanged, no new imports (`postgresClient` already imported at the top of the file).
+
+## Decisions Made
+- Category `'finance'` chosen for the PAX8 health row (matches `qbo`'s billing/subscription-data classification) since the `IntegrationHealth['category']` union has no vendor/marketplace member — per plan instruction, the union was not extended.
+- The disabled-check in the route is a standalone inline query, not a shared helper with the forthcoming scheduler branch (13-03) — per plan D-01, this separation is intentional for this phase.
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## Threat Flags
+
+None — both edits are covered by the plan's own `<threat_model>` (T-13-01 mitigated by the 403 gate, T-13-04 mitigated by the constant-literal query, T-13-05 accepted for the error message). No new undocumented surface introduced.
+
+## Known Stubs
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Both `checkConfigOnly('pax8', ...)` in `integration-health.ts` and the 403 gate in `app/api/pax8/sync/route.ts` are ready for 13-03's live verification (row appears on `/admin/integrations`, 403 confirmed when toggled off) and the scheduler branch (`pax8-daily` in `sync-scheduler.ts`) which reuses the same `SELECT disabled FROM integration_settings WHERE key = 'pax8'` query shape.
+- No blockers.
+
+## Self-Check: PASSED
+
+All claimed files exist (`lib/services/integration-health.ts`, `app/api/pax8/sync/route.ts`, this SUMMARY.md) and all claimed commits (`3c114ae`, `fdc9919`, `6413f99`) are present in git history.
