Auto-registration never completed: the firmware announced on the wrong
topic, the hub never replied, and an unregistered node couldn't receive a
reply anyway. Switch to self-assigned IDs:
firmware (esp32-mqtt-bridge.cpp):
- camera_id defaults to the device id (clientID, e.g. rig-86d978)
- always subscribe to <id>/command; announce on the contract topic
remoterig/cameras/<id>/announce (was the unmatched announce-<id> form)
- drop the bogus numeric timestamp from status (node has no clock)
hub (subscriber.go):
- handleAnnounce registers new cameras under the node's self-assigned id
(no cam-NNN, no registered reply)
- handleStatus tolerates an empty/invalid timestamp and stamps server-side
(previously rejected the status outright)
docs/MQTT_CONTRACT.md updated to match.

The project was designed around a 10.60.1.0/24 travel-router network,
but the actual RemoteRig router uses 192.168.8.0/24 (the C6 associates
and gets 192.168.8.x; hub confirmed at 192.168.8.56). Replace the
network prefix everywhere (last octet preserved; GoPro 10.5.5.1 left
alone).
- scripts/setup-pi.sh: static IP 192.168.8.56/24, gateway 192.168.8.1,
deploy/health command examples updated
- esp32-mqtt-bridge.cpp: default mqtt_broker -> 192.168.8.56
- firmware/data/config.json: broker -> 192.168.8.56 (wifi_password kept
blank in git; real value flashed to the device only)
- docs (CONTEXT, MQTT_CONTRACT, READMEs, wireframes): gateway/hub/DHCP
and example IPs re-addressed for consistency

Updating the buried ESP-01S currently means a USB-UART adapter and a
GPIO0 jumper. Add a path to change its settings without reflashing, and
lay the groundwork for full firmware updates over the existing UART.
set_config (no reflash for settings):
- ESP-01S: add saveConfig() + a set_config command — updates GoPro
SSID/password/IP and poll interval, persists to LittleFS, acks, and
re-associates Wi-Fi if creds changed
- XIAO: forward an MQTT set_camera_config down to the ESP-01S over UART
(hub -> MQTT -> XIAO -> UART -> ESP-01S/LittleFS)
UART-OTA groundwork ("XIAO as flasher"):
- reserve XIAO GPIOs ESP01_RST_PIN=D8, ESP01_PGM_PIN=D10 for driving the
ESP-01S serial bootloader (not driven yet)
- docs/design/esp01s-uart-ota.md: full design (why Wi-Fi OTA doesn't fit
the 1MB ESP-01S on the GoPro AP, bootloader entry, ROM flash protocol,
HTTP-pull delivery, scope)
- hardware/README.md: fix stale ESP32-C3 -> XIAO ESP32-C6 wiring, add the
two control lines (Notion wiring diagram updated to match)
Both firmwares build clean and are flashed; set_config round-trip needs
the broker to exercise end-to-end.

Defines topic hierarchy, payload schemas, QoS levels, heartbeat
protocol, camera auto-discovery via announce topic, offline
buffering strategy, and command/response flow for start/stop.
Architecture: travel router subnet (192.168.4.x), Pi Zero 2 W
runs Mosquitto + Go backend, ESP32s dual-STA to GoPro AP +
travel router. No internet dependency.
Closes CUB-238.
