TOUCH CRASH (the blue screen): app_on_touch ran a blocking WebSocket send (up to 5s) directly in the LVGL touch callback, stalling the MIPI-DSI flush into a garbage/blue frame + task-watchdog reboot on every tap. Now touch_cb only gives a semaphore; a dedicated app_task does the blocking sends, audio, and face changes off the render thread. WS send timeout cut 5s to 1.5s as belt-and-braces. RAIN = REACHABILITY (user request): rain now falls only while the gateway WebSocket is live (gated on gw_connected in rain_tick). It drains gracefully on disconnect, resumes on reconnect, a genuine glanceable reachable signal. Idle density bumped 2 to 4 so connected-idle reads distinctly from disconnected-black. CALM THE WEDGE CHURN (user request): transient wifi/WS drops no longer slam to the x_x error face or a CONNECTING banner. Boot goes straight to the calm idle face (dry until connected). Only a sustained 30s+ outage escalates to x_x (clock_cb); the ~15s wedge-recovery just shows a brief rain pause. Two fixes from adversarial concurrency review before flashing: - persistent single capture task (was xTaskCreate per utterance; a rapid re-tap or WS-stop-vs-app-start race could put two readers on one mic/I2S handle and corrupt the codec) - reset s_talking on disconnect (app_on_disconnect) so the first tap after a mid-utterance drop starts fresh, not the stop branch Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
