VLAP4P FR3 training set, Azure-camera variant

The data the Azure-camera policy (taalyelxor/vlap4p-fr3-azure-310000, run 20261003T230324Z) was fine-tuned on: the project's 125 human and 496 accepted Isaac Lab Mimic demonstrations (621 trajectories, 115,604 steps), re-rendered from saved simulator states with the overhead camera placed to match photographs of the real cell's Azure Kinect. Actions, proprioception, instructions and wrist images are those of the original data set (the reference-camera RLDS: jclarky/vlap4p-training-data). Simulated data only. Files sit at their repository paths (download into a checkout of the VLAP4P repository).

Path What
data/experiments/fr3_azure_overhead/rlds/fr3_tabletop_multitask_azure_overhead/1.0.0/ RLDS (TFDS) training set; overhead 256x256 (centre square, rotated 180 deg), wrist 640x480
data/isaac-sim/.../stages/fr3_azure_overhead_workcell.usd the workcell stage with the Azure overhead camera (needs the simulation assets)
data/experiments/fr3_azure_overhead/20261003T230324Z/ training run manifest (exact command), completion manifest (checkpoint SHA256s), statistics
data/experiments/fr3_azure_overhead/20261003T121445Z/ an earlier attempt that crashed during training (no checkpoints)
data/experiments/fr3_azure_overhead/bowl_checkpoint_test/ 16-episode check of checkpoints 302500-310000 on bowl on plate
data/experiments/fr3_azure_overhead/*.json, *.log, *.png camera placement and re-render checks, re-render and training logs

Recipe and configuration: configs/azure_overhead/ and docs/AZURE_CAMERA_POLICY.md in the repository.
