Deterministic provenance for one rollout root, target, and policy.

These fields bridge the immutable VIN source row to the rollout replay tables. Source lineage identifies the original shard-local VIN row, target lineage describes the actor-visible target and GT evaluation match, and config hashes bind candidate generation, oracle scoring, and rollout policy choices without embedding heavy source artifacts.
