# Phase 01: Foundation Verification Report

**Phase Goal:** The project skeleton exists — data models, API shell, device registry, and a working terminal-aesthetic UI shell the rest of the system will fill in.
**Verified:** 2026-04-05T20:30:00Z
**Status:** human_needed (all automated checks pass; visual and interaction quality requires human review)
**Re-verification:** Yes — after gap closure via plan 01-04

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | A device can be registered with name, strip type, LED count, IP, and port — and survives an app restart | VERIFIED | POST /api/devices fully implemented; DeviceRegistry.save/load with aiofiles; devices.json present with real data |
| 2 | A show file can be saved and reloaded as JSON with schema_version, audio reference, device snapshot, and empty track list | VERIFIED | ShowStore.save/load using model_dump_json/model_validate_json; ShowModel has schema_version=1, audio: AudioRef, devices: list[DeviceConfig], tracks: list[TrackModel] |
| 3 | The web app loads in a browser with terminal/hacker aesthetic — dark background, monospace fonts, no generic SaaS look | VERIFIED (human confirm) | index.html served via StaticFiles; --bg-primary: #0a0a0a, JetBrains Mono, --accent: #00ffff; visual quality requires browser check |
| 4 | FastAPI serves the frontend and exposes REST stubs for shows and devices | VERIFIED | Container Up ~1hr; uvicorn on 0.0.0.0:8000; StaticFiles at "/"; GET/POST /api/devices and GET/POST/GET-list /api/shows all implemented |
| 5 | Adding a new strip type requires only a new device class — no changes to core engine code | VERIFIED | _DEVICE_CLASSES dict in registry.py is the sole extension point; BaseDevice ABC enforces interface contract |
| 6 | DEVICES panel has an add-device form and device list area | VERIFIED | index.html line 28: form#add-device-form with name/strip_type/led_count/ip/port inputs and "+ ADD DEVICE" submit button |
| 7 | Form submit calls POST /api/devices; remove button calls DELETE /api/devices/{id} | VERIFIED | app.js lines 118-136: form submit handler calls apiPost("/api/devices", data); removeDevice() calls apiDelete(/api/devices/${id}) |
| 8 | CSS uses --accent: #00ffff as the canonical accent variable | VERIFIED | style.css line 6: `--accent: #00ffff`; lines 7,10: --border-bright and --text-accent are var(--accent) aliases |
| 9 | index.html has panel IDs for all four panels | VERIFIED | devices-panel (line 23), animations-panel (line 41), timeline-panel (line 48), transport-panel (line 53) — all present |

**Score:** 9/9 truths verified

|----------|---------------|--------|--------------------|--------|
| `app.js` loadDevices() | `devices` array | `GET /api/devices` → `state.registry.list_all()` → `_devices` dict loaded from `devices.json` | Yes — loaded from devices.json via aiofiles on startup | FLOWING |
| `app.js` form submit | posted data | form field values → `apiPost` → `POST /api/devices` → `DeviceConfig.model_validate` + `registry.add()` + `registry.save()` | Yes — real write to devices.json | FLOWING |
| `app.js` removeDevice | device id | onclick attribute → `window.removeDevice(id)` → `apiDelete` → `DELETE /api/devices/{id}` → `registry.remove()` + `registry.save()` | Yes — real delete from devices.json | FLOWING |
| `api/shows.py` list_shows() | `summaries` list | `show_store.list_ids()` → glob `shows/*.json` | Yes — reads real .json files | FLOWING |

## 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; container Up ~1hr |
| INF-02 | 01-01 | Modular device abstraction — new strip type = new class + dict entry | SATISFIED | BaseDevice ABC + _DEVICE_CLASSES registry in registry.py; adding new type requires only new class + one dict entry |
| DEV-01 | 01-01, 01-03 | Register device with name, strip_type, led_count, ip, port | SATISFIED | POST /api/devices with DeviceConfig Pydantic validation; all fields present in model |
| DEV-02 | 01-01, 01-03 | Devices persist across sessions (stored in config file) | SATISFIED | DeviceRegistry.save/load with aiofiles to devices.json; file present with real device data |
| DEV-03 | 01-02, 01-04 | Device list shown in UI — enable/disable per show | SATISFIED | loadDevices() renders device rows; add-device form in DEVICES panel; remove buttons on each row; POST/DELETE wired and functional |
| SHW-01 | 01-01, 01-03 | Show files saved/loaded as JSON with schema_version | SATISFIED | ShowStore.save() writes 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 via FastAPI |
| UI-02 | 01-02, 01-04 | Terminal/hacker aesthetic — dark, monospace, CRT vibe | SATISFIED | --bg-primary: #0a0a0a, JetBrains Mono, --accent: #00ffff canonical variable; .device-form and .device-remove styled in terminal aesthetic; no generic SaaS styling found |

**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) 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""` | Info | Explicitly deferred to Phase 3; no Phase 1 requirement depends on it |
| `lightsync/devices/ws2801.py` | 26 | `encode_animation_cmd` returns `b""` | Info | Same — Phase 3 scope |
| `lightsync/api/ws.py` | — | WebSocket echo stub | Info | Intentional Phase 1 placeholder; Phase 2 will implement protocol |

No blockers. All previously blocking anti-patterns (missing form, missing apiPost/apiDelete) have been resolved.

## Human Verification Required

### 1. Terminal Aesthetic Quality and Device Form Visibility

**Test:** Open https://lightsync.groll.cloud in a browser (authenticate via Authelia as admin). Inspect the DEVICES panel.
**Expected:** LIGHTSYNC header with cyan title; DEVICES panel with device list (if any devices registered) and the add-device form at the bottom — inputs for name, strip_type dropdown, led_count, ip, port, and "+ ADD DEVICE" button. Dark background (#0a0a0a), JetBrains Mono font, cyan accents (#00ffff), no rounded corners on panels, no drop shadows, no gradients.
**Why human:** Visual appearance and the CRT/terminal aesthetic quality of UI-02 cannot be verified programmatically.

### 2. Device Add and Remove Flow

**Test:** Fill the add-device form (e.g., name="Test Strip", sk6812, 60 LEDs, IP 192.168.1.100, port 21324) and click "+ ADD DEVICE". Then click the x remove button on the new device.
**Expected:** Submitting creates the device via POST /api/devices and the device appears in the list immediately without page reload. The x remove button calls DELETE /api/devices/{id} and the device disappears from the list. No errors in browser console.
**Why human:** Form interaction, state update after POST, and remove button behavior require live browser testing.

---

## Gap Closure Summary

**Previous state (gaps_found, 7/9):**
- Gap 1: Missing add-device form in DEVICES panel — index.html had no form, app.js had no POST/DELETE
- Gap 2: CSS variable naming mismatch (--text-accent vs --accent) and missing panel IDs

**Current state (human_needed, 9/9):**
- Gap 1 CLOSED: form#add-device-form added to index.html with all 5 inputs + submit; apiPost, apiDelete, removeDevice, form submit handler all added to app.js; window.removeDevice exported for onclick compat
- Gap 2 CLOSED: --accent: #00ffff added as canonical variable; --border-bright and --text-accent are now var(--accent) aliases; all four panel IDs (devices-panel, animations-panel, timeline-panel, transport-panel) added to index.html

All 9 automated must-haves verified. Remaining items are visual and interaction quality checks that require a browser.
