1-bit bus alone did not stop the sdio_write timeout wedge (recurred
at ~5min uptime). Modem power save is the new prime suspect: the C6
napping mid-SDIO-transaction matches the minutes-scale periodicity.
Always-powered appliance -> PS_NONE costs ~50mW and removes the
entire failure class if correct. SDIO clock also halved to 10MHz.

Night-watch caught the instability in the act at 7min uptime:
E H_SDIO_DRV: sdio_write_task: Failed to send data: 258 (timeout)
E H_SDIO_DRV: Unrecoverable host sdio state -> SW_CPU_RESET
i.e. esp-hosted-mcu#167. Known mitigation: 1-bit SDIO bus (#148),
still ~80x voice bandwidth. Also: recovery reboots no longer ring
the gong (esp_reset_reason gate) - a butler doesn't bong at 3am.

Root cause of the dead data path (assoc/scan/RPC fine, zero data
frames): esp-hosted 1.4.x is formally incompatible with IDF 5.5
(esp-hosted-mcu#47) and the factory C6 slave firmware was ancient
(couldn't even answer a version RPC). Waveshare's examples pin 1.4.* —
do not follow them.
Fix:
- host: espressif/esp_hosted ^2.12 (+ esp_wifi_remote 1.6)
- slave: 2.12.11 network_adapter.bin embedded in the app (c6_ota.c
streams it to the C6 over the SDIO RPC channel at boot when the
reported version is < 2.x; ~10s, no wires, idempotent)
- RAM diet for hosted 2.x's footprint (MEMPOOL_PREFER_SPIRAM,
reduced WIFI_RMT buffers) — without it internal SRAM famine
boot-loops in xTaskCreateStaticPinnedToCore before app_main
- conservative 20MHz SDIO clock for first verified data path
Verified on hardware: DHCP lease (even that healed), 8/8 pings to
router and tower-of-joy at 1-5ms, WebSocket to the gateway connected,
device registered at /devices as desklock-p4 with fw version.
Also: wifi_diag.c L1 SoftAP diagnostic mode (DESKLOCK-DIAG) with
review fixes, boot ping ladder in net.c, static-IP fallback,
face_status() line, docs for the whole failure taxonomy.

- gateway: GET /devices registry (per-IP connect count, timestamps,
device/fw from new 'hello' protocol event); graceful utterance
errors -> error event; uvicorn ws-ping-timeout 120s
- firmware: hello on WS connect; static 192.168.86.53 fallback after
15s without DHCP; scan-on-boot removed (kept for diagnostics);
ping_interval 8s; fonts regenerated --no-compress (compressed
glyphs render blank with LV_USE_FONT_COMPRESSED off); 8MB factory
partition; montserrat_28; LVGL lock timeout semantics fixed
- docs: sauron endpoint plan, power ladder, versioning policy
Known issue: 'Outside' AP association succeeds but no L2 traffic
flows (no DHCP, no ARP) — worked once at 22:05 then never again;
ToJ side verified clean. Investigation ongoing.

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.

User verdict: audible and butler-non-intrusive on the bare 2W speaker.

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
