### User-facing changes
|
|
|
|
#### Features
|
|
|
|
##### Multi-broker MQTT devices
|
|
|
|
- The device editor now shows an MQTT **broker picker** for `device_type=mqtt` (in both the add-device and device-settings modals), wired into load / save / validate / dirty-check / clone. An empty selection means "first available broker"
|
|
- `mqtt_source_id` is now threaded end-to-end through `DeviceCreate` / `DeviceUpdate` / `DeviceResponse` and the device routes; the referenced broker is validated on create **and** update ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
|
|
|
|
##### Schema-driven wiring-graph editor
|
|
|
|
- The visual graph editor now renders ports and edges generically from a backend-served schema (`GET /api/v1/graph/schema`) instead of hard-coding the connectable-field topology in two places — so client and server can no longer drift
|
|
- New `GET /api/v1/graph` returns the full nodes + edges + validation topology, and `GET /api/v1/graph/dependents/{kind}/{id}` reports what references an entity ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
|
|
|
|
##### Aggregated snapshot endpoint
|
|
|
|
- New `GET /api/v1/snapshot` returns all output targets (with processing state + metrics), devices (with brightness), the source / preset / clock lists, and the system block in a **single response** — collapsing the Home Assistant integration's previous ~2N+M request fan-out into one round trip
|
|
- `?include=` fetches only a subset of sections, and an excluded section also skips its server-side work (e.g. cold-cache hardware brightness probes or the blocking NVML performance query) ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
|
|
|
|
#### Bug Fixes
|
|
|
|
- **Graceful shutdown no longer hangs:** uvicorn's graceful-shutdown wait is now bounded (`GRACEFUL_SHUTDOWN_TIMEOUT`, shared by the desktop, Android, and demo launchers). A lingering events WebSocket (which the browser auto-reconnects) used to keep connections from draining, so the lifespan shutdown never ran — leaving LED targets lit and blocking process exit. Ctrl+C / OS shutdown with the UI open now reliably stops targets and checkpoints the DB ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
|
|
- **Device update error codes:** `update_device` no longer masks an intentional 4xx (e.g. an unknown `mqtt_source_id` or failed group validation) as a generic 500 ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))

### Development / Internal
|
|
|
|
#### Backend
|
|
|
|
- **Wiring-graph schema engine** (`api/graph_schema.py`): a pure, unit-tested module that is the single source of truth for which reference fields connect which entity kinds; builds the topology and performs dependency lookup plus cycle / dangling-reference detection without booting the app or any store. The route layer only gathers serialized entities and delegates ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
|
|
- **Structured access log:** a new middleware emits one structured line per request, attributing it to the authenticated token's friendly label (the key name, **never** the secret) so traffic can be traced to a client (e.g. `homeassistant` vs `android`). uvicorn's own access log is disabled to avoid duplicate lines ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
|
|
- Shared `validate_mqtt_source_exists` (`_mqtt_validation.py`) deduplicates the MQTT-source existence check between the device and output-target routes ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
|
|
|
|
#### Frontend
|
|
|
|
- Service-worker refresh for the new bundle ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
|
|
|
|
#### Tests
|
|
|
|
- New suites: graph routes + schema engine, snapshot routes, access-log middleware, `mqtt_source_id` device regressions, and the bounded-shutdown entrypoint. Full suite: **1614 passing** ([a5effba](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a5effba))
