RED.httpNode.post registers a raw express route with no body parser, so
req.body was undefined and trigger payloads showed all fields null. Add
a zero-dep readJsonBody helper that streams + parses req body.
Trigger nodes now self-contained inputs (inputs:0):
- Each registers POST /api/internal/<topic> on RED.httpNode
- Angie returns 404 for any /api/* not whitelisted (kiosk/pair/admin)
so external requests cannot trigger BF nodes
- Server bridge POSTs direct to nodered container (bypasses Angie)
- nodered-bridge.ts updated to use /api/internal/<topic>
- 6 trigger nodes converted: display-power, layout-changed,
kiosk-changed, camera-changed, status, kiosk-camera-event
- Optional per-node filters (display_id, kiosk_id, camera_id)
- close handler removes only this node's route layer
- bf-status: query kiosk state by ID via /api/admin/kiosks/:id
- bf-trigger-status: dedicated heartbeat-only topic kiosk.status
(skips connect/disconnect noise from kiosk.changed)
- bf-snapshot: GET /admin/entities/:id/snapshot as Buffer for
motion → email/telegram flows
- coordinator-ws now forwards both kiosk.changed (event=heartbeat)
AND kiosk.status on every status message
