Project State

Project Reference

See: .planning/PROJECT.md (updated 2026-04-05)

Core value: Load a song, build a synchronized light show, play it back live — with precise control over every effect on every device. Current focus: Phase 02 — audio-engine

Current Position

Accumulated Context

Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

Init: Web UI over TUI — richer DAW interactions while keeping terminal aesthetic via CSS
Init: python-mpv-jsonipc preferred over ctypes binding — no libmpv.dll dependency on Windows
Init: Firmware deferred to Phase 7 — protocol must be validated against simulator first
Init: undo/redo built in Phase 4 — retrofitting command pattern is expensive
[Phase 01-foundation]: Module-level state in main.py for registry/show_store — acceptable for Phase 1, Phase 2 migrates to Depends()
[Phase 01-foundation]: StaticFiles mounted last in create_app() — prevents catch-all interception of /api/* routes
[Phase 01-foundation]: encode_animation_cmd stubs return b'' — Phase 3 implements real UDP animation command encoding
[Phase 01-foundation]: redirect_slashes=False on FastAPI — StaticFiles at root intercepted API redirects
[Phase 01-foundation]: API collection routes use empty-string paths ('') not '/' — canonical /api/devices without redirect
[Phase 01]: window.removeDevice export required for ES module onclick compatibility — functions in type=module scripts are not global
[Phase 01]: CSS accent variable canonical naming: --accent is source of truth, aliases are text-accent and border-bright
[Phase 02-audio-engine]: MPV_AO env var controls audio output — null default for Docker server mode, overridable for local dev
[Phase 02-audio-engine]: 10Hz polling via time.sleep(0.1) over observe_property — observe_property fires per audio frame overwhelming asyncio
[Phase 02-audio-engine]: apply_timer_fix() as Linux no-op — timeBeginPeriod is Windows-only; INF-03 satisfied as platform-guarded stub

Pending Todos

None yet.

Blockers/Concerns

Phase 2: python-mpv-jsonipc latency on Windows 11 under load is unbenchmarked — validate with timing harness in 02-01
Phase 4: librosa MP3 loading path on Windows needs explicit validation (soundfile falls back to audioread which requires FFmpeg on PATH)
Phase 6: AI sync approach (LLM-assisted) has no reference implementation — treat as spike, not commitment
