# Previous training data: versioned location and checksum index

`TRAINING_DATA_INDEX.json` tells you which retained training inputs belong to
which model, their original/current snapshot roles, exact file SHA256/size,
and an immutable owner-authorized private backup revision. The same index is
attached at the roots of `diffusion-gif/any2ego` and `diffusion-gif/trick-prediction`.
No original restricted annotation bodies, credentials or original machine paths
are in this public index. This index is not a license grant for source data.

## Important distinctions

- Legacy mix6 SFT step900: train16,174 / heldout3,228; old multi-point protocol.
- Legacy mix6 GRPO step250: the corresponding original train/heldout Parquet,
  8 embedded observation-frame data URIs per record and identical SID sets.
- All19,402 original mix6 NPZ observations and old JSON/Parquet are privately
  preserved byte-for-byte, with independent tar-member checksum readback.
- The later joint dataset31,202/5,015 and public simulation subset17,421 records
  must not be substituted as the original training data of those old weights.
- Any2Ego original JSON/CSV, full PhiSeg source manifests and the common32,558
  export are separate snapshots. Captioner trainer args identify their source
  JSON files; generator per-component launch-time subset hashes were not saved.

The index records **retained file snapshot hashes**, not nonexistent hashes
from the original training launch. The large Ego-Exo original RGB/GT-mask pool
is NOT remotely backed up here. Original-run data identity and permanent
third-party availability cannot be guaranteed merely by a JSON index.

## Fetch your original training files

Use an account authorized for the PRIVATE vault. Log in locally; do not put a
real token in scripts or chat. This keeps gated/restricted annotations private.

```bash
pip install huggingface_hub
hf auth login
python fetch_training_data.py --index TRAINING_DATA_INDEX.json --dataset legacy_mix6_sft --output data_download
# inspect the dry-run plan, then:
python fetch_training_data.py --index TRAINING_DATA_INDEX.json --dataset legacy_mix6_sft --output data_download --execute
python restore_legacy_mix6.py --snapshot-root data_download/snapshots/20261104 --output ready_mix6 --execute
# GRPO: choose --dataset legacy_mix6_grpo; --dataset all_private fetches the entire protected snapshot.
```

Downloads are pinned to immutable commits, verify exact hashes, and never
overwrite a different existing user file. The restore helper changes only
`npz`/`frames_root` in WORKING JSON copies; all frozen originals remain intact.
Keep a separate local/private copy for long-term availability.
