New pipelineAuthority

Built from the new pipeline

The new pipeline is the authority for credential qualification. These numbers are read from the qualification view derived from the official credential-eval run of the public-evidence-snapshot population. The regression and policy populations keep their own counts on the qualification pages and are not added in here.

Maintainer-reviewed (independent review pending)

598 fixtures of the 7,041 in evidence release snapshot-2026.10.06.4 carry this label. They are counted in the numbers on this page.

Passed the project’s own verification (source evidence, automated checks, recorded counter-arguments); not yet independently reviewed.

OpenRedaction default (all patterns): not measured in this run (optional)

The default (all-pattern) profile is slow and noisy for credential evaluation: personal data and resource identifiers dominate its findings, and its last official measurement took 7 minutes of scanner time on a population the credential profile scans in seconds (its methods run takes 40+ minutes), so it is a manual measurement and never blocks other scanners or core verification (#763). Its earlier results stay as history with their run identity; the credential profile is a separate scanner, never spliced with it.

Last measurement: policy-corpus@linux-x64 (configuration sha256:2451ce7bf380), public-evidence-snapshot+methods@linux-x64 (configuration sha256:d47d081ce5fb), public-evidence-snapshot@linux-x64 (configuration sha256:2451ce7bf380), regression-corpus@linux-x64 (configuration sha256:2451ce7bf380) · engine 0.1.0-alpha.5 · recorded 2026-10-05 · retained record, no longer listed by the run registry. It stays labelled with that run identity and is never combined with another profile or another run.

OpenRedaction credential profile (33 types): not measured in an official run (local exploratory diagnostics only: see ADR)

The credential profile is the comparison profile chosen in docs/decisions/2026-10-06-choose-the-openredaction-credential-bearing-profile-as-the-comparison-scanner.md. It is optional in the official run class because no pinned engine configuration measures it yet: making it required would refuse every official view until the owner approves the one profile-only run. Its own history starts with that run; nothing of the default's is reused for it.

No earlier measurement of it is recorded. Nothing is shown in its place.

Official measurement: pending: requires owner approval (one profile-only run; see the decision).

Provider documentation 2021-04 prefix scheme · observed 2026-09-17 · ghp_/gho_/ghu_/ghs_/ghr_ prefixes and underscore separator; 36-character body is tool-corroborated (checksum in the last six characters per github.blog/2021-04-05)
trufflehog 3.97.4
gitleaks 8.30.1

Re-checked 2026-09-20 (#46): docs.github.com also documents github_pat_ (fine-grained token) as a real, different prefix outside this contract's ghp_/gho_/ghu_/ghs_/ghr_ set, backing a prefix twin. github.blog/security/application-security/behind-githubs-new-authentication-token-formats confirms the parenthetical checksum claim (CRC32, Base62-encoded, last six characters) but the checksum is not part of this contract's lexical pattern, so a checksum-only mutation still satisfies it and cannot be constructed as a twin here.

What the run recorded, by group

Detector views overlap, so their groups are never summed across detectors. Other scanners are reference values on the same inputs, in run order.
