## Dataset Structure

Minari-compatible flat table format. Use `minari-export` for native [Minari](https://minari.farama.org/) HDF5 format.

Each episode has N step rows plus one terminal observation row (N+1 pattern).
The terminal observation is the final state after the last step — it has an empty action
and null values for rewards/terminations/truncations/infos.

- **episode_id** (`binary(16)`): Unique UUID identifier for each episode (16 bytes, universally unique across all recordings)
- **seed** (`int` or `null`): RNG seed used for `env.reset()` (set on first row of each episode, `null` on other rows)
- **observations** (`Image`): RGB frame from the environment
- **actions** (`list`): Action taken at this step (`[]` for terminal observations)
- **rewards** (`float` or `null`): Reward received (`null` on terminal observation rows)
- **terminations** (`bool` or `null`): Whether the episode terminated naturally (`null` on terminal observation rows)
- **truncations** (`bool` or `null`): Whether the episode was truncated (`null` on terminal observation rows)
- **infos** (`str` or `null`): Additional environment info as JSON (`null` on terminal observation rows)
- **session_id** (`binary(16)`): UUID grouping all episodes from one `gymrec record` run
- **collector** (`string`): Who collected the data (`"human"`, `"random"`, or future agent names)
- **gymrec_version** (`string`): Version of gymrec used to record (e.g. `"0.1.0+abc1234"`)
