User verdict: audible and butler-non-intrusive on the bare 2W speaker.
Recorded as the house sound signature in architecture.md.

Additive gong synthesis: seven inharmonic partials with per-partial
decay (fundamental 165Hz rings 2.6s, highs die in 0.2s), a detuned
pair for shimmer, 45ms distant attack, and three feedback-comb
reflections (95/210/370ms, net gain .93) for a dense stone-space tail.
Normalized to -12dBFS at codec volume 58: quiet but voluminous.
Synthesized into PSRAM at boot (~4s), plays 5s, blocking is fine for
bring-up — audio moves to its own task in phase 2.

C5->E5 half-second chime with fade-out at boot, right after the face
renders. Codec opens in slave mode, esp_codec_dev write path works.
Phase 1 bring-up is now complete: display, touch, audio, 200MHz PSRAM.

- firmware boots to a rendered LVGL face in 1.57s (eyes + smile + tag)
- sdkconfig: CONFIG_IDF_EXPERIMENTAL_FEATURES=y unlocks SPIRAM 200MHz
(silently degraded to 20MHz before -> MIPI-DSI underrun -> LVGL lock
starvation -> task watchdog); mirrors official 08_lvgl_demo_v9 config
- architecture.md: power management section (user prime concern) —
active/ambient/dormant/night ladder, levers, hard edges, <=300ms wake
- AGENTS/CLAUDE: replace stale bring-up warnings with verified commands

The gateway service now lives in system-admin-toj/containers/stacks/
tatlock-ui.yml (shared docker-dataplane network: speaches by service
name, host-run Tatlock by LAN IP). Drop deploy/desklock-gateway.yml.

Live smoke test showed /v1/chat/completions replies open with the
Steward's <think> block (Open WebUI convention) — without stripping,
the device would speak the internal monologue aloud.

Settles the Python version question: floor >=3.11, no ceiling.
Container moves to python:3.13-slim, CI tests on 3.13. The embedded
Piper fallback resamples with numpy (already present via [speech]).
Verified with a live round trip at 16 kHz.

- Face: new 'rage' state — 3-frame kaomoji loop (stare, flip the table,
put it back) for in-flight request failures; 'error' stays the quiet
persistent face for a dead link. Sim + artifact + design doc updated.
- Gateway: stt.py/tts.py are now pluggable backends. Default 'speaches'
talks OpenAI-format HTTP to the live container on :8601
(faster-whisper-small STT, Kokoro bm_george TTS with 24->16 kHz
audioop resample); 'embedded' fallback kept behind the [speech] extra.
Verified with a live TTS->STT round trip (warm: STT 0.27s, TTS 1.9s).
Docker image is now slim (no CUDA/ML deps). Python pinned to 3.12
(system 3.8 too old, audioop gone in 3.13).
- CI: .gitea/workflows/build.yml — lint+test on main pushes; on v* tags
test, build gateway image, push to registry, release, and trigger
Watchtower (tatlock pattern; needs REGISTRY_USER/REGISTRY_PASSWORD/
WATCHTOWER_TOKEN secrets). Runtime stack in deploy/desklock-gateway.yml.
- architecture.md: measured speech latencies, deployed-Speaches status,
CI & deployment section.

- 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
