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.

Provider screening signals
NPI-keyed source families read directly for 1407082407: federal and state integrity lists, CMS Open Payments, Order and Referring eligibility, Medicare opt-out, and enrollment revalidation. Cells expose the source and provenance fields supplied by the selected record. A screening aid — re-confirm any match against the primary source before acting; absence means nothing on file in the data Fonteum currently holds, never a guarantee none exists.

Pick a date to reconstruct, or two dates to diff. Equivalent JSON: /api/v1/history/{subject_type}/{subject_id}?at=… and …/diff?from=…&to=…
