## Accumulated Context

### Decisions

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

- [Roadmap]: Hardware-first build order — ESP32 is the validation target for all Pi-side work; developing against a mock risks protocol mismatches late.
- [Roadmap]: WiFi+RMT coexistence must be tested on day 1 of Phase 1 (documented FastLED #1657, February 2026 — actively problematic on single-core ESP32-C3).
- [Roadmap]: SK6812 is RGBW (4 bytes/LED) — configure explicitly before any animation code; retrofitting requires protocol version bump.

### Pending Todos

None yet.

### Blockers/Concerns

- [Phase 1]: ESP32-C3 RMT+WiFi coexistence has conflicting documentation — test simultaneously on first flash.
- [Phase 1]: GPIO pin assignment for simultaneous RMT (SK6812) + SPI (WS2801) on SuperMini needs hardware validation.
- [Phase 2]: aubio 0.4.9 ARM pip wheel on Raspberry Pi OS bookworm unverified — may require source build.
- [Phase 2]: sounddevice + miniaudio simultaneous PipeWire access needs early testing.
