From f6d1c6f606c04b03fdbdedf952541eb4724ef70f Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 6 Apr 2026 11:21:10 -0400 Subject: [PATCH] feat: implement REST API endpoints for settings, zones, portals, triggers, notifications, replay - Added SettingsHandler with GET/PATCH /api/settings for configurable settings - Added ZonesHandler with full CRUD for zones (GET/POST/PUT/DELETE /api/zones) - Added PortalsHandler with full CRUD for portals (GET/POST/PUT/DELETE /api/portals) - Added TriggersHandler with full CRUD for automation triggers including test endpoint - Added NotificationsHandler for notification channel config and test notifications - Added ReplayHandler for CSI replay sessions (start/stop/seek/tune endpoints) - All endpoints follow OpenAPI-style patterns with appropriate godoc comments - Settings persist to SQLite across restarts - Zone/portal updates reflected in live 3D view via WebSocket Endpoints implemented: GET/PATCH /api/settings GET/POST/PUT/DELETE /api/zones GET/POST/PUT/DELETE /api/portals GET/POST/PUT/DELETE /api/triggers POST /api/triggers/{id}/test GET/PATCH /api/notifications/config POST /api/notifications/test GET/POST /api/replay/sessions POST /api/replay/start POST /api/replay/stop POST /api/replay/seek POST /api/replay/tune Co-Authored-By: Claude Opus 4.6 --- mothership/cmd/mothership/main.go | 53 ++
