Cross-source identifiers
Every current identifier attachment, with the link method and confidence carried verbatim — deterministic links are 1.000; probabilistic links surface their real matcher confidence, never rounded up.

Current record
Current claims returned for this entity, grouped by provenance subject. The table exposes the source identifier recorded for each claim.
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 Most facts have no superseded row; dates outside retained coverage may return no prior version, and diffs require both coordinates.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=…
