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.

Authority: new
Population: public-evidence-snapshot
Engine: credential-eval 0.1.0-alpha.16

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).

Benchmark dossier notes

From the provider dossier, as written. The evidence level above says how well the format is backed; a fact the dossier does not record is not shown.

Shape: no documented prefix; 40 alphanumeric characters [A-Za-z0-9], recognised only beside a same-line cohere name, CO_API_KEY, the API host or an SDK constructor. Never a bare 40-character run. The length is not provider-stated.
Basis: T2 at best; #868 records that no provider has T1 here. One gitleaks rule (cohere-api-token, keyword then [a-zA-Z0-9]{40}) is the only length source. GitGuardian says "Prefixed: False" with no length. The SDK does no validation. GitHub secret scanning lists a Cohere pattern without publishing it. A vendor blog claims a co- prefix; it contradicts both scanners, has no example and no second source, and was not adopted.
Issuance: not attempted. Dashboard API keys page, key names cannot contain spaces, shown once, revocable in the web UI or CLI. The #782 checklist compares a trial and a production key.
Contract in core: detector-families.md, section Keyword-gated provider keys (#868). #932 recognised the Java Cohere.builder().token(...) form; a masked_-led LiteLLM log value stays unreported by policy.

Benchmark dossier questions

Things the sources do not settle. They are listed so nobody reads them as settled.

Open caveat: No provider source states any shape; 40 alphanumeric is one gitleaks rule's inference, so contextual only. Needs one trial and one production key measured (checklist in #782).

Looks like it, but isn't

Values the dossier records as resembling this credential without being one.

Collisions: SHA-1-length hex and random ids, org_ and user_ ids from the check-api-key response, and unrelated co- strings.

Scanner rules for this family

Mapped by hand (reviewed 2026-09-30) from each scanner's pinned rule file, never from what a scanner found on the fixtures.
