LilyGo T-Display P4 (ESP32-P4 + factory ESP-AT C6) reaches POC: LoRa mesh, Wi-Fi companion (TCP:5000), GPS, SD, battery gauge, chat persistence, and now: - Web VNC/REMOTE/terminal via a first-byte router on the single ESP-AT listener (HTTP verbs -> WS server, '<' frames -> phone companion; both live at once). C6Server gains a _begun gate so never-listening instances stay inert. - VNC freeze fixed: bounded one-CIPSEND-chunk drains under the WS client mutex (a whole-band blocking write starved the main loop), fast-drop of stalled mirror clients, SEND-OK wait 8s->4s. - Wi-Fi robustness: CWJAP? miss-streak tolerance, CIPSERVER liveness verify + re-arm (a re-association silently killed the listener until reboot). - Time sync: HTTP-Date fallback when SNTP is blocked; ClockFloorRTC gains a MAX_PLAUSIBLE_EPOCH guard (all boards) after a garbage-future hardware RTC read (2043) latched the ratchet. - Brightness: RM69A10 DCS 0x51 driven live (CC slider + persisted pref). - Sound: ES8311 + NS4150B notification chimes (P4Audio, esp-bsp-derived register sequence on Wire1), full HAS_UI_SOUND surface + CC Screen/Sound sliders; ccVolumeReleaseCb's hardcoded tanBeep -> uiSoundPreview. - tdisplay_p4/: IDF project (build.sh, c6_at AT-over-SDIO driver, sdkconfigs, fetch-deps.sh vendoring, .gitignore for local payloads).
