validate_seed_alignment

validate_seed_alignment(trajectory_file: EpisodeTrajectoryDataSource, group_by: list[str]) -> list[str]

Return the store group_by fields that the trajectory does not carry.

The store keys segments by its (alias-resolved) group_by expressions, read from each segment's captured values. A trajectory whose captured expressions do not include those fields would silently collapse into a partial/empty bucket key, so the caller raises on a non-empty result. This guards the contract between the C# exploration capture (the .oet labels) and the Python store keys.

Parameters:

• trajectory_file (EpisodeTrajectoryDataSource) – The trajectory to check.
• group_by (list[str]) – The store's resolved group_by fields.

Returns:

• list[str] – The group_by fields missing from the trajectory's captured values.
