1 RolloutZarrStoreReader

rollouts.RolloutZarrStoreReader(store_dir)

Open and validate standalone rollout replay stores.

1.1 Methods

Name	Description
array	Read an array by slash-separated Zarr path.
validate	Validate row linkage, masks, and initial `Q_H` target availability.
manifest	Read root attrs and the top-level sidecar manifest without payload arrays.
q_h_view	Return the padded finite-candidate `Q_H` training view.

1.1.1 array

rollouts.RolloutZarrStoreReader.array(path)

Read an array by slash-separated Zarr path.

1.1.2 validate

rollouts.RolloutZarrStoreReader.validate()

Validate row linkage, masks, and initial Q_H target availability.

1.1.3 manifest

rollouts.RolloutZarrStoreReader.manifest()

Read root attrs and the top-level sidecar manifest without payload arrays.

1.1.4 q_h_view

rollouts.RolloutZarrStoreReader.q_h_view(discount_gamma=None)

Return the padded finite-candidate Q_H training view.

With default arguments this reads the persisted derived q_h/ group. Passing discount_gamma recomputes the view from the canonical factual tables for audits and ablations.
