The device now runs the complete face contract on glass: seven states
with glyph expressions (custom 140px face font), matrix rain as pooled
label streams (22px DejaVu+Noto katakana font), rage kaomoji frames
(64px), orbit arc + elapsed counter wait cues, blink/talk/thought
animations, idle clock (SNTP, Europe/Amsterdam), and the power ladder
(active/ambient 35%/dormant 5% with rain parked).
Voice path: ES7210 mic capture task streams 16k PCM over
esp_websocket_client to the gateway; reply PCM buffers to PSRAM and
plays via the audio task; touch-to-talk (tap to speak, tap to send).
Protocol mapping per docs: thinking->effort, audio->speaking,
error event->rage (auto-composes after 2 loops), WS loss->error face.
Bring-up fixes: 8MB factory partition (fonts overflowed 1.5M),
bsp_display_lock(0) is try-lock in this adapter (use UINT32_MAX),
gong synth yields to feed IDLE0, wifi scan diagnostics (found SSID
case mismatch), esp_websocket_client pinned ~1.3 (1.4 needs IDF>5.5).
Verified on hardware: boots, connects to Wi-Fi and holds an open
WebSocket to the gateway. Sauron (iMac TTY endpoint + ops console)
planned in architecture.md.

- sim/face/index.html: browser simulator of the 800x800 round panel with
six states (idle/listening/pensive/effort/speaking/error), state-driven
rain density, blink/talk/thought animations, idle clock
- effort state gets hard-required wait cues: orbiting bezel arc, elapsed
counter, max rain (Tatlock turns run 10-25s)
- rain driven by setInterval, not rAF: renders under the screenshot
tool's --virtual-time-budget and mirrors LVGL lv_timer
- architecture.md: Face design contract (state table, protocol mapping,
LVGL port notes) + latency table updated to GPU-era benchmarks
(Steward ~6s warm, full flow 11-25s; old CPU-era figures retired)

- STT/TTS move to a shared Speaches container (OpenAI-format, GPU, port
8601 proposed); gateway becomes a thin orchestrator with pluggable
speech backends (speaches default, embedded fallback)
- Record the on-device ceiling: WakeNet wake word, VAD, ES7210 AEC,
optional MultiNet fixed commands; open-vocabulary STT permanently out
- Record the real latency bottleneck (Tatlock ~2 min full local flow):
gateway must stream chat tokens and synthesize sentence-by-sentence
- Plan reply_delta + barge-in protocol additions

DeskLock gives the Tatlock butler a face and voice on a Waveshare
ESP32-P4-WIFI6-Touch-LCD-3.4C round display in the living room.
- firmware/: ESP-IDF project targeting esp32p4 with the Waveshare XC BSP
- gateway/: FastAPI voice bridge (faster-whisper STT, Tatlock chat, Piper TTS)
- docs/architecture.md: component design and device<->gateway WS protocol
