From 245bbe89bbfee4d819233e5a91558cde9454ba5b Mon Sep 17 00:00:00 2001 From: jedarden Date: Thu, 9 Apr 2026 18:17:51 -0400 Subject: [PATCH] docs: verify REST API implementation completeness All required REST API endpoints have been verified as implemented: - Settings (GET/POST /api/settings): SQLite-backed with cache - Zones & Portals (CRUD): WebSocket broadcast for live 3D view - Automation Triggers (CRUD + test): VolumeTriggersHandler with webhook/MQTT/Ntfy - Notifications (config + test): Inline handlers with quiet-hours support - Replay/Time-Travel (sessions, start, stop, seek, tune): CSI recording buffer - BLE Devices (list, update): Device registry with person assignment All handlers include OpenAPI-style godoc comments and proper error handling.
