├─ Timeline Logger (IF.TTT audit)
└─ WebSocket broadcast (real-time updates)

Database Schema

• camera_snapshots: 20 fields, 4 indexes, full audit trail

• audit_log: IF.TTT compliance with Ed25519 signatures

API Endpoints (6 Total)

• POST /api/webhooks/events/home-assistant (webhook receiver)
• GET /api/boats/{boat_id}/snapshots (gallery with filters)
• GET /api/snapshots/{snapshot_id} (individual retrieval)
• GET /api/boats/{boat_id}/live-feeds (feed discovery)
• POST /api/boats/{boat_id}/alerts (alert creation)
• GET /api/boats/{boat_id}/camera-stats (statistics)

Mobile UI (6 Screens)

1. Quick check dashboard ("Is my boat OK?")
2. Snapshot gallery (infinite scroll, 2x2 grid)
3. Full screen viewer with CV overlay
4. Live camera feed player
5. Alert management panel
6. Camera configuration screen

Computer Vision

• Model: YOLOv8 custom fine-tuning + YOLO-Marine
• Target Classes: tender, person, radar, chartplotter, solar panels, life raft, etc.
• Confidence Thresholds: >90% auto-populate inventory, 75-90% user confirm, <75% skip
• Processing: Hybrid (edge on HA NUC + cloud verification)

4. Mobile App Capability: Confirm video.js + HLS support
5. Integration with S2-H07: Search indexing strategy for snapshots
6. Coordination with S2-H02: Equipment detection confidence thresholds

Conclusion

S2-H04 has delivered a comprehensive, security-hardened camera integration specification that enables boat owners to answer "Is my boat OK?" from anywhere. The design balances simplicity (mobile-first quick check) with power (full gallery, live feeds, CV analysis). The hybrid manual + camera-assisted inventory detection approach directly responds to S2-H02's needs while maintaining user control.

The specification is ready for implementation, with clear API contracts, database schemas, and security requirements documented. All integration points with other agents have been identified and cross-referenced.

Status: ✅ READY FOR SYNTHESIS (S2-H10)
