Summary

Major infrastructure sprint — 11 new commits establishing the complete RemoteRig system architecture across backend, frontend, deployment, firmware, and hardware.

Backend (Go)

• MQTT subscriber (internal/mqtt/subscriber.go) — Full Mosquitto integration with auto-reconnect, status/heartbeat/announce handling, camera auto-registration (MAC → cam-NNN), recording event auto-open/close, heartbeat watchdog (120s offline), SSE broadcast
• SSE hardening — Typed events (event: camera_status), monotonic event IDs for Last-Event-ID reconnection, CORS preflight
• Frontend embedding — Go binary embeds React build via //go:embed, SPA fallback, dev-safe placeholder

Deployment (CI/CD + Scripts)

• ARM64 cross-compile — build-dev.yaml builds Go for GOARCH=arm64 (Pi Zero 2 W) + bundles React
• SCP deploy — deploy-dev.yaml pushes binary + config to Pi, systemd restart with backup/rollback
• Pi provisioning — scripts/setup-pi.sh idempotent setup (Mosquitto, static IP 192.168.4.10, systemd)
• Systemd service — scripts/remoterig.service auto-restart, after mosquitto

ESP32 Firmware (PlatformIO)

• firmware/ — PlatformIO project with dual-STA Wi-Fi (travel router + GoPro AP), GoPro Hero 3 HTTP API, 60-byte status blob parser, MQTT per contract, auto-registration, heartbeat, command handling

Hardware Design

• 3D printable case — OpenSCAD model (hardware/case/remoterig-case.scad) — GoPro Hero 3 sleeve, ESP32 compartment, LiPo tray
• Hardware guide — BOM (~$20/node), wiring diagram, print settings, field workflow

Documentation

• MQTT contract — Full topic hierarchy, payload schemas, QoS levels
• CONTEXT.md — Fully rewritten with closed-network architecture, accurate issue status

Architecture Decision

All devices connect to a self-contained travel router (192.168.4.0/24). No internet dependency. Pi Zero 2 W at 192.168.4.10 runs Mosquitto + Go backend + React UI. ESP32s bridge GoPro AP to LAN via MQTT.

Related Issues

Closes: CUB-232 (MQTT subscriber), CUB-233 (SSE verification), CUB-237 (CONTEXT.md), CUB-238 (MQTT contract)

Unblocks: CUB-174 (ESP32 firmware — now has scaffold), CUB-231 (Mosquitto setup — scripts ready), CUB-230 (offline buffering)

docs: add comprehensive project context file (CONTEXT.md) for agent reference 02fa6e4d4f

docs: add MQTT message format contract with closed-network architecture ... df212796d2

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.

- Replaced architecture diagram with travel router LAN design
- Added MQTT contract reference
- Updated issue status table with agent assignments
- Revised known limitations to reflect actual gaps
- Added network config section (subnet, static IP)
- Removed CUB-182 (canceled duplicate)

Post-sync: 13 done, 15 backlog, 1 in review, 1 canceled.

feat: add MQTT subscriber for ESP32 camera status ingestion ... f200cd9782

Implements MQTT subscriber (internal/mqtt/subscriber.go) that:
- Connects to Mosquitto broker with auto-reconnect
- Subscribes to remoterig/cameras/+/status, +/heartbeat, +/announce
- Parses and validates incoming messages per MQTT contract
- Inserts status_logs with duplicate prevention
- Auto-detects recording state changes and manages recording_events
- Broadcasts camera status changes via SSE hub
- Camera auto-registration via announce (MAC-based, sequential cam-NNN)
- Heartbeat watchdog marks cameras offline after 120s silence
- Wired into main.go with graceful degradation (warns if broker unreachable)

Dependency: github.com/eclipse/paho.mqtt.golang v1.5.0

Closes CUB-232.

feat: harden SSE endpoint with typed events and Last-Event-ID ... 607aea514b

- Added monotonic event ID (Last-Event-ID) for reconnection support
- Events now emit typed: 'event: camera_status' for client-side filtering
- Initial connection event sends 'event: connected' with ID
- Reconnection acknowledgment via Last-Event-ID header
- CORS preflight (OPTIONS) handler
- Access-Control-Allow-Headers: Last-Event-ID
- Initial heartbeat shortened to 15s for faster detect (30s for steady)

Closes CUB-233.

- Cross-compile with GOOS=linux GOARCH=arm64 for Raspberry Pi Zero 2 W
- Build React frontend at repo root (npm ci && npm run build) producing dist/
- Remove old web/ working-directory and explicit embed step (handled by go:embed)
- Repository dispatch event_type unchanged: dev-build-success

deploy(dev): rename OpenClaw to RemoteRig, add config.yaml deployment ... 74d6130dd5
