/check/history
Verification history
Every retained attempt of a Check for one subject. Read-only: this page runs nothing.
Attempt 1 is shown as “Failed”. That label is an explicit owner migration ruling (2026-10-05) for the producer’s “not established” state, not a producer fact. The reason code is the producer’s own.
Attempt 1 is a controlled negative specimen. It used a deliberately incorrect expected archive-member digest (its artifact reference ends :hostile-expected-digest), so ARCHIVE_MEMBER_DIGEST_MISMATCH must not be read as evidence that the upstream archive was corrupt. See the xz replay controls.
Retained verification history is a build-time export included in this release. It does not refresh when this page is requested.
Verification history
2 retained Check attempts for this subject.
Attempts are listed in the order they were retained. No dates are carried, so none are shown.
- Failed: 1
- Established: 1
Results are what the producer carried for each attempt. They are not a finding of truth, support, or currentness, and a later attempt does not replace an earlier one.
