## Data Coverage Caveats
|
|
|
|
- Current project data fully supports still-image frame-center checks for 60 mapped images.
|
|
- Derkachi project data supports synchronized video/IMU/GPS trajectory replay for FT-P-03 and NFT-PERF-02.
|
|
- Derkachi project data is calibration-limited: raw camera intrinsics, lens distortion, and camera-to-body transform are still required before final absolute accuracy thresholds can be treated as production acceptance.
|
|
- Phase 3 must validate camera calibration inputs and public/calibrated dataset acquisition before FT-P-03, FT-P-04, and NFT-PERF-02 can be used for final signoff.
|
|
- Cycle 1 Docker replay smoke evidence currently passes blackbox, performance, resilience, and security infrastructure scenarios; Jetson resource evidence remains a target-hardware release gate and is reported as blocked on local runners.
