| # Checkpoint monitoring trajectories | |
| Each complete episode row links to immutable transition tables and lossless PNG | |
| chunks. The episode index retains Run, training seed, Checkpoint, evaluation, | |
| episode conditions, actions, rewards, boundaries and source/runtime provenance. | |
| Frames are full unmasked native RGB at the contracted action cadence. Chunk joins | |
| preserve the initial and true terminal image without duplicated transitions. | |
| Staged chunks without a complete episode index are not dataset episodes. | |
| Monitoring is observational and never Acceptance evidence. Use whole-Run or | |
| training-seed-group holdouts to avoid leakage across correlated Checkpoints; | |
| split assignment is left to consumers. R2 sources remain canonical. | |
