+"""E2E harness — runs a DatasetAdapter through FlightProcessor and collects output.
+
+The harness instantiates `FlightProcessor` with a minimal in-memory repository
+and an event sink instead of the real SSE streamer. It pushes adapter frames
+through `process_frame()` and records each emitted FrameResult for comparison
+against the adapter's ground truth.
+
+What the harness does NOT do:
+  - Train/tune ESKF noise parameters (use adapter-specific defaults)
+  - SE(3) trajectory alignment (callers apply as needed)
+  - Image decoding beyond OpenCV (extended formats handled per-adapter)
