| 5 | ShowStore saves ShowModel as JSON and loads it back | VERIFIED | `shows/` directory has `.json` files; `model_dump_json`/`model_validate_json` wiring confirmed |
| 6 | `python -m lightsync` starts FastAPI without error | VERIFIED | Container running (`Up 3 minutes`), uvicorn logs show "Application startup complete" |
| 7 | Frontend loads in browser showing DAW skeleton layout | VERIFIED | `GET /` serves `index.html` via StaticFiles; LIGHTSYNC header, panels present |
| 8 | DEVICES panel has add-device form and device list area | FAILED | `index.html` has `#device-list` but no `add-device-form`; `app.js` has no POST/DELETE operations |

## Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|----------|
| INF-01 | 01-01, 01-03 | Python 3.11 backend (FastAPI + uvicorn) | SATISFIED | `FROM python:3.11-alpine`, FastAPI app running |
| INF-02 | 01-01 | Modular device abstraction — new strip type = new class + dict entry | SATISFIED | BaseDevice ABC + _DEVICE_CLASSES registry pattern |
| DEV-01 | 01-01, 01-03 | Register device with name, strip_type, led_count, ip, port | SATISFIED | POST /api/devices fully functional with DeviceConfig validation |
| DEV-02 | 01-01, 01-03 | Devices persist across sessions (stored in config file) | SATISFIED | devices.json persists via DeviceRegistry.save/load; file present with data |
| DEV-03 | 01-02, 01-03 | Device list shown in UI — enable/disable per show | PARTIAL | Device list displayed (loadDevices() fetches and renders); add/remove form ABSENT — user cannot add/delete devices from UI |
| SHW-01 | 01-01, 01-03 | Show files saved/loaded as JSON with schema_version | SATISFIED | ShowStore.save() writes `show.model_dump_json()`; schema_version=1 in ShowModel |
| SHW-02 | 01-01, 01-03 | Show includes audio, device snapshot, animation blocks, beat analysis | SATISFIED | ShowModel has audio: AudioRef, devices: list[DeviceConfig], tracks: list[TrackModel], analysis: AnalysisBlock |
| UI-01 | 01-02, 01-03 | Web app served by Python backend | SATISFIED | StaticFiles mount at "/" serves index.html; GET / returns HTML |
| UI-02 | 01-02 | Terminal/hacker aesthetic — dark, monospace, CRT vibe | PARTIAL | Dark background (#0a0a0a), monospace JetBrains Mono, cyan accents PRESENT and correct; CSS variable naming differs from plan spec (--text-accent vs --accent); visual quality needs human review |

**Orphaned requirements check:** All 9 required IDs (INF-01, INF-02, DEV-01, DEV-02, DEV-03, SHW-01, SHW-02, UI-01, UI-02) are declared in phase plans. No orphaned requirements.

## Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `lightsync/devices/sk6812.py` | 27 | `encode_animation_cmd` returns `b""` (stub) | Info | Explicitly deferred to Phase 3; does not block Phase 1 goal |
| `lightsync/devices/ws2801.py` | 26 | `encode_animation_cmd` returns `b""` (stub) | Info | Same — Phase 3 scope |
| `lightsync/frontend/app.js` | — | No device add/remove implementation | Blocker | DEV-03 requires device list in UI with interaction; read-only display is incomplete |
| `lightsync/frontend/index.html` | — | Missing `add-device-form` entirely | Blocker | No form means users cannot add devices through the web UI |
| `lightsync/api/ws.py` | 43 | WebSocket echo stub | Info | Intentional Phase 1 stub; does not block any Phase 1 requirement |

## Human Verification Required

### 1. Terminal Aesthetic Quality

**Test:** Open https://lightsync.groll.cloud in a browser (authenticate via Authelia as admin). Inspect visual presentation.
**Expected:** Consistent terminal/hacker aesthetic — pure black background (#0a0a0a), JetBrains Mono throughout, cyan (#00ffff) used for accents/borders, no rounded corners on panels (status dot rounding is acceptable), no drop shadows, no gradients.
**Why human:** CSS variable naming changed from spec (`--accent` -> `--text-accent`, `--border-bright`) but functional effect may be equivalent. Visual fidelity of the "CRT/scanline vibe" requirement (UI-02) requires eyes.

### 2. Device List Rendering

**Test:** After confirming a device exists in devices.json, load https://lightsync.groll.cloud and inspect the DEVICES panel.
**Expected:** Device name and metadata visible in the panel. OFFLINE/CONNECTED status indicator changes to CONNECTED when WebSocket connects.
**Why human:** Rendering of device rows and WebSocket status indicator requires live browser environment.

## Gaps Summary

Two gaps block full phase goal achievement:

**Gap 1 — Missing device CRUD UI (DEV-03 partial):** The frontend displays the device list (read-only) but has no mechanism to add or remove devices through the browser. The `index.html` is missing the `add-device-form` element and `app.js` has no `apiPost`, `apiDelete`, or `removeDevice` functions. Users must currently use `curl` to manage devices. This partially satisfies DEV-03 (list shown) but fails the interaction requirement (enable/disable per show implies UI control).

**Gap 2 — CSS variable naming deviation:** Plan 01-02 artifact specifies `contains: "--accent"` but CSS uses `--border-bright` and `--text-accent`. The visual result is equivalent but the contract check fails. Additionally `index.html` lacks the required panel IDs (`devices-panel`, `animations-panel`, `timeline-panel`, `transport-panel`) that plan acceptance criteria specified.

**Not a gap — encode_animation_cmd stubs:** Both SK6812Device and WS2801Device return `b""` from `encode_animation_cmd`. This is explicitly deferred to Phase 3 and does not block Phase 1 goals.

**Core Phase Goal Assessment:** The phase goal "Prove the tech stack works end-to-end: backend API, device registry, show store, WebSocket stub, and deployable Docker container on groll.cloud" is substantially achieved. Backend API, device registry, show store, WebSocket stub, and Docker deployment all work. The gap is in the frontend device management UI which was a secondary goal of plan 01-02.
