Point-in-time
Query retained claim coordinates under bitemporal-read/v1. Most facts have no superseded row; dates outside retained coverage may return no prior version, and diffs require both coordinates.
Pick a date to reconstruct, or two dates to diff. Equivalent JSON: /api/v1/history/{subject_type}/{subject_id}?at=… and …/diff?from=…&to=…
