    provides: compiled form/list schemas, operation permission gates, and schema-projected CRUD/bulk services
provides:
  - Registered Artists admin controller with complete embedded Winter form and list assets
  - Permission-first Artist schema, list, create, update, show, delete, and bulk-delete routes
  - PostgreSQL acceptance coverage for projection, lifecycle normalization, pagination, atomicity, and retry safety

key-decisions:
  - "Artists uses only the shared cabana list and CRUD engines; the controller contains identity, asset paths, model factory, and permission declaration only"
  - "Winter Artist YAML is copied without reducing fields, columns, toolbar behavior, labels, or layout hints"
  - "Artist name_key and slug remain model-owned lifecycle fields and are not exposed by the admin writable projection"

patterns-established:
  - "Pattern: global catalog resources register a zero-state AdminController with one operation permission and a typed NewRecord factory"
  - "Pattern: activation embeds both list and form assets because registry compilation validates the complete controller contract at boot"

# Phase 9 Plan 07: Artists Admin Controller Summary

**A complete permission-gated Artists admin controller now serves unchanged Winter form/list schemas and inherits the shared deterministic CRUD and atomic bulk contracts.**

## Performance

- **Duration:** 2h 20m (includes two stalled executor attempts before inline fallback)
- **Started:** 2026-09-25T17:28:00Z
- **Completed:** 2026-09-25T19:48:22Z
- **Tasks:** 2
- **Files modified:** 9

## Accomplishments

- Embedded and strictly compiled every tracked Artist form field, list column, toolbar action, locale key, layout hint, and default in source order.
- Registered `golem15.fonoteka.artists` with `golem15.fonoteka.access_artists`, enforced before schema localization or Artist database access.
- Proved shared list, projected CRUD, lifecycle normalization, atomic bulk deletion, duplicate normalization, and retry-safe repeated deletion on assembled PostgreSQL routes.

## TDD Gate Compliance

The RED commit `35b04e7` established failing form, registration, permission, list, CRUD, and bulk contracts before the GREEN controller/assets commit `e595617`. Task 2 edge refinements landed in `5964c8c`; the final `^TestArtistsAdmin` suite passes.

## Task Commits

1. **Task 1: Port Artists form schema and controller registration** - `35b04e7` (test, fonoteka.go), `e595617` (feat, fonoteka.go)
2. **Task 2: Port Artists list and prove inherited CRUD/bulk edges** - `35b04e7` (test, fonoteka.go), `5964c8c` (test, fonoteka.go)

The framework repository required no production change for this plan, so its measured commit count is zero. Fonoteka commits span `35b04e7..5964c8c`.

## Files Created/Modified

- `fonoteka.go/plugins/golem15/fonoteka/controllers/artists_admin_controller.go` - Artist controller identity, model factory, asset path, and permission map
- `fonoteka.go/plugins/golem15/fonoteka/controllers/artists/config_form.yaml` - unchanged Winter form-controller contract
- `fonoteka.go/plugins/golem15/fonoteka/controllers/artists/config_list.yaml` - unchanged Winter list-controller contract
- `fonoteka.go/plugins/golem15/fonoteka/models/artist/fields.yaml` - complete Artist form fields and layout hints
- `fonoteka.go/plugins/golem15/fonoteka/models/artist/columns.yaml` - complete Artist list columns
- `fonoteka.go/plugins/golem15/fonoteka/admin_artists_test.go` - assembled permission, schema, list, CRUD, and bulk acceptance suite
- `fonoteka.go/plugins/golem15/fonoteka/admin.go` - embeds the four Artist schema assets
- `fonoteka.go/plugins/golem15/fonoteka/controllers/genres_admin_controller.go` - adds Artists to the plugin controller roster

## Decisions Made

- Kept Artists as a zero-state controller. All query, projection, validation, lifecycle, transaction, and response behavior remains in the shared cabana engines.
- Kept `name_key` and `slug` out of the writable schema. `models.Artist.BeforeValidate` derives them, and hostile request values are dropped.
- Preserved raw phrase keys when translations are absent, matching the established phrasebook fallback contract.

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Embedded list assets during form/controller registration**
- **Found during:** Task 1
- **Issue:** Cabana activation compiles a controller's list contract before its optional form contract, so registering Artists with only form files fails boot.
- **Fix:** Copied and embedded the unchanged Winter `config_list.yaml` and `columns.yaml` in the registration commit; Task 2 then exercised them through real routes.
- **Files modified:** `controllers/artists/config_list.yaml`, `models/artist/columns.yaml`, `admin.go`
- **Verification:** `TestArtistsAdminRegistration`, `TestArtistsAdminList`
- **Committed in:** `e595617`

---

**Total deviations:** 1 auto-fixed (1 blocking)
**Impact on plan:** The files were already Task 2 deliverables; only their activation timing moved earlier. No scope was added.

## Issues Encountered

The configured `gsd-executor` stalled twice without creating files or commits. Artifact reconciliation confirmed no partial plan work, so execution continued inline under the two-task threshold. Test fixtures were adjusted to respect the existing unique `name_key` constraint and PostgreSQL `int4` primary-key range.

`ADMIN-01`, `ADMIN-02`, and `ADMIN-04` remain pending in `REQUIREMENTS.md` because later Phase 9 plans also declare them.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

Ready for 09-08 through 09-10. Artists is complete; Genres, Styles, and Collections remain the Wave 7 peers.

## Self-Check: PASSED

- FOUND: `fonoteka.go` commits `35b04e7`, `e595617`, and `5964c8c`
- FOUND: Artists controller plus all four embedded Winter schema assets
- PASSED: `GOCACHE=/tmp/summercms-go-build go test ./plugins/golem15/fonoteka -run '^TestArtistsAdmin' -count=1`
