# Four-setting checkpoint index

This directory groups the release assets by experimental setting. Each setting uses the same six logical entries:

1. `common_start/`: the branch point used by all continuation methods;
2. `uniform/`: the Uniform continuation checkpoint;
3. `residual/`: the Residual-OPTR (ReTime) continuation checkpoint;
4. `keyframe/`: the KF-Weight continuation checkpoint;
5. `frameskip/`: the FrameSkip continuation checkpoint;
6. `loss_is/`: the active Loss-IS continuation checkpoint.

The `common_start` entry is the resumable training state. Method endpoints are evaluation-ready model snapshots unless a setting README explicitly lists additional training-state files. Shared source code remains at repository root; each setting README records the corresponding step, model family, environment and method dependencies.

| Setting | Common start | Continuation endpoint |
|---|---:|---:|
| Florence–Bridge | 20,000 | 20,500 |
| Florence–RoboTwin | 10,000 | 10,500 |
| Qwen3-VL-4B–Bridge | 29,000 | 29,500 |
| Qwen3-VL-4B–RoboTwin | 11,000 | 11,500 |

No implementation-path or self-referential checksum gate is required for launch. Reproduction should still validate the model family, dataset, episode/anchor support, proposal semantics, batch contract and training budget.
