Update autodev state documentation to reflect progress in the Decompose phase, changing the current step from 5 to 6. Revise sub-step details to indicate a shift to phase 2, focusing on module layout for the Satellite Service and Tile Manager, and awaiting confirmation before product task decomposition. Additionally, enhance problem documentation to clarify the original still-image sample limitations and introduce the Derkachi representative fixture for improved data validation. Update references to the Tile Manager and Satellite Service throughout the documentation for consistency.

+# Derkachi Representative Flight Fixture
+
+## Files
+
+| File | Description | Observed Metadata |
+|------|-------------|-------------------|
+| `flight_derkachi.mp4` | Cropped nadir flight footage for replay | H.264, 880 x 720, 30 fps, about 490.07 s |
+| `data_imu.csv` | Flight-controller telemetry trace exported from the tlog | 4,900 rows at 10 Hz from `Time=0.0` to `489.9`; includes `SCALED_IMU2` and `GLOBAL_POSITION_INT` trajectory fields |
+
+## Test Use
+
+Use this fixture for video/telemetry synchronization checks, representative replay smoke tests, VIO hot-path latency, frame-drop accounting, and trajectory comparison against `GLOBAL_POSITION_INT`. The video and telemetry align at exactly three video frames per telemetry row. Camera intrinsics, lens distortion, raw camera resolution, and exact camera-to-body calibration are still unknown, so this fixture is not sufficient by itself for final production camera calibration or satellite-anchor accuracy claims.
+
+For the test recording, the rotating camera was mechanically fixed in a downward/nadir orientation. Treat the MP4 as a cleaned/cropped replay fixture rather than the raw camera feed.
