replayable against the source bytes. No trust in Verzi required. Replay this receipt →

Illustrative. The document names and doc-ids are real; dollars, versions, spans and hashes are placeholders. The version in force on a date is not typed. It is resolved live by the archive: GET /v1/archive/docs/lcd:33718/as-of?date=2024-01-15 (public, no key). The composed /rules response ships Q4 2026; the source archive and as-of resolution are live today.

Warranted, not cited. Calibrated, not confident.

One CPAP line, denied. On the left is what you open by hand to fight it: the actual files, in their actual formats. On the right, Verzi's answer, a warrant with the source, the pointer, the version and a hash you can replay against the bytes yourself. Same question, every payer meeting: what was true on the date of service?

Everyone rebuilds this. Nobody shares it. The public files are the card network. Verzi is the Stripe.

Move the date, and three of the four warrants resolve to a different file

Verified in the archive on L33718: version 48 in force 2021-09-27 to 2023-12-31; version 49 from 2024-01-01; current live version is 52. A date of service of 2024-01-15 resolves to v49. Four weeks earlier resolves to v48. The "as of" engine picks the one in force and returns its hash. It never guesses.
