Find timestamped changes across released evidence dimensions for a resolved property since a caller-supplied timestamp, with deterministic change fingerprints, source-snapshot digests, per-source observational summaries, explicit timestamp semantics, source gaps, and a machine-readable next-check contract for repeat polling.
