+# continuum-ai-worker
+
+Computer-vision failure detection worker for the Continuum print farm
+platform. Consumes camera frame batches pushed onto the Redis Stream
+`stream:camera_frames` (by `continuum-backend`'s `src/queue/`), runs them
+through an ONNX Runtime model, and fast-paths high-confidence failure alerts
+back to Redis and Postgres.
+
+## Pipeline
+
+```
+continuum-proxy --(frames)--> continuum-backend --(XADD)--> stream:camera_frames
+                                                                    |
+                                                          XREADGROUP (this worker)
+                                                                    v

+                                                  src/reporter (Redis pub/sub + Postgres INSERT)

+## Structure

+```
+src/
+  main.rs         Consumer-group loop: XREADGROUP -> decode -> infer -> report -> XACK
+  inference/       Thread-safe ONNX Runtime session wrapper + pre/post-processing
+  reporter/        Alert fan-out: Redis pub/sub for realtime UI, Postgres for audit trail

+## Getting started
+
+```bash
+cp .env.example .env
+# place an ONNX failure-detection model at ./models/failure-detector.onnx
+cargo run
