Beta.12 arrival family bitwarden-secrets-manager-access-token (#528, product redact-secret#1019), contract in benchmarks/lib/beta8/528a.ts from the #1014 handoff bitwarden.md. T1 on every part (provider SDK parser, server generator, docs example). Neither pinned scanner has a Bitwarden rule. Since the 4fb7882 re-pin the product detector is in the pinned registry, so the row maps to it.

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
Evidence: snapshot-2026.10.06.4
Run: sha256:4bec6e539482…
Recorded: 2026-10-07
Authorised for: @redact-secret/core@0.1.0-beta.14

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: 0. + a UUID + . + exactly 30 [A-Za-z0-9] + : + 22 standard Base64 + == (94 in all).
Basis: every part T1 under R1: the provider SDK parser (version, UUID, a key that decodes to 16 bytes), the server generator (30 alphanumerics) and the docs example (segment lengths).
Issuance: not attempted; the grammar is T1 from provider sources, so no key is needed.
Contract in core: detector-families.md (row on main; the Beta.12 detector, redact-secret#1019, merged in redact-secret#1039 and is unreleased).

Looks like it, but isn't

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

Collisions: none known; a semantic version followed by a UUID and Password Manager user.<uuid> client ids are benign siblings. An unpadded key is parser-accepted but never issued, so it is outside the family.

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.
