Status and reason text are shown exactly as FMCSA publishes them. The change date is FMCSA's status_change_date; “Dataset updated” is when FMCSA last published the file, and “Fetched” is when VAX read it. The two authority files are shown side by side and are not reconciled by VAX. Amounts: the dictionary says “thousands”, but published values look like dollars, so raw values are shown. Census status is not authority.

Bars run only between published effective and cancellation dates. Current filings show their effective date only — no end is assumed and no continuous coverage is inferred. Current history: 3uet-3z4i; legacy rows from 6sqe-dvqs (frozen 2026-05-14) are kept only when not already in the current file.
