plan: 12
subsystem: admin
tags: [security, postgres, openapi, authorization, acceptance]

requires:
  - phase: 09-backend-admin-authentication-and-schema-pipeline
    provides: Backend guard, controllers, schemas, CRUD, relations, permissions, and settings
provides:
  - Route-derived Phase 9 security matrix across guard, cabana, and the assembled app
  - Fresh PostgreSQL admin migration rollback that preserves other histories
  - Fail-closed phase gate and committed admin OpenAPI contract
affects: [phase-10-spa, admin-api]

  tasks: 3
  commits: 4

tech-stack:
  added: []
  patterns:
    - "The mounted admin route table is the permission matrix; a new handler without the backend guard fails the gate"
    - "OpenAPI admin paths are generated from cabana annotations and checked against that same route list"
    - "PostgreSQL stages fail when a TestPhase09 test is skipped or matches nothing"

# Phase 9 Plan 12: Security, PostgreSQL, OpenAPI, and Acceptance Summary

**The admin surface now has one fail-closed gate for guard isolation, route permissions, real PostgreSQL, and the committed OpenAPI contract.**

## Performance

- **Duration:** 3h
- **Started:** 2026-09-27T00:30:00+02:00
- **Completed:** 2026-09-27T03:05:00+02:00
- **Tasks:** 3
- **Files modified:** 14

## Accomplishments

- Added `TestPhase09GuardIsolation`, `TestPhase09PermissionMatrix`, and `TestPhase09SecurityCoverage`.
- Added assembled route and denial tests plus a PostgreSQL journey across the five admin controllers, settings, and the editors relation.
- Added `scripts/check-phase9.sh` with self-test, security, postgres, openapi, and evidence stages.
- Regenerated `fonoteka.go/docs/openapi.json` from the public genre route and the cabana admin annotations.
- Recorded threat evidence in `09-SECURITY-REVIEW.md` and replaced the pending validation rows.

## Task Commits

1. **Task 1: Build a non-bypassable Phase 9 security matrix** - `30bfd2d` (summercms.go), `336a90b` (fonoteka.go)
2. **Task 2: Gate all routes, PostgreSQL behavior, and committed OpenAPI** - `4392550` (summercms.go), `feaca6b` (fonoteka.go)
3. **Task 3: Record independent threat evidence and finalize Nyquist mappings** - docs commit on summercms.go

## Files Created/Modified

- `bouncer/backend_guard_test.go` - cross-guard token matrix
- `cabana/security_coverage_test.go` - mounted route inventory and adversarial fixtures
- `cabana/admin_openapi.go` - swag annotations for every D-09 route
- `cabana/phase09_contract_test.go` - committed OpenAPI inventory
- `scripts/check-phase9.sh` - fail-closed phase gate
- `lagoon/backend_admin_migrations_test.go` - fresh migrate/rollback/reseed
- `fonoteka.go` `admin_phase09_security_test.go`, `admin_phase09_e2e_test.go`, `docs/openapi.json`, `scripts/check-openapi.sh`

## Decisions Made

- Swag documents exported functions in `cabana/admin_openapi.go`. The mount test fails if that list and `service.mount` disagree.
- Rollback uses a dedicated database so the shared assembled test database stays intact for the rest of the package.

## Deviations from Plan

### [Rule 3 - Blocking] TDD tests passed on the first run

**Found during:** Task 1
**Issue:** The guard, permission order, projection, and migration behavior already existed from plans 09-01 through 09-11. A new assertion written against that behavior passed immediately, so there was no honest RED commit.
**Fix:** Committed the new tests as `test(09-12)` once they passed. The gate still fails if a later change removes the control.
**Files modified:** `bouncer/backend_guard_test.go`, `cabana/security_coverage_test.go`, `lagoon/backend_admin_migrations_test.go`
**Verification:** `scripts/check-phase9.sh --evidence`
**Commit:** `30bfd2d`

**Total deviations:** 1
**Impact:** No production control was weakened. The new tests are the regression net the plan asked for.

## Issues Encountered

None.

## User Setup Required

None.

## Next Phase Readiness

Plan 09-12 is executed. Phase 9 still needs its verification report before the roadmap phase checkbox can close.

## Self-Check: PASSED

- `bouncer/backend_guard_test.go` exists
- `scripts/check-phase9.sh` exists
- `09-SECURITY-REVIEW.md` exists
- Commits `30bfd2d`, `336a90b`, `4392550`, and `feaca6b` are present
