1 RolloutZarrRecord

rollouts.trace.RolloutZarrRecord(result, lineage, rollout_id_prefix)

One counterfactual rollout result plus source/target lineage.

CounterfactualRolloutResult owns the generated trajectories and candidate shells. RolloutLineage owns where those trajectories came from. The Zarr writer flattens this pair into normalized source, target, rollout, step, and candidate tables.
