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).

Documentation for the one property varied in legacy twin fixtures (context twin: same-line twilio keyword or SK API Key SID removed): Un-probeable record lifted 2026-09-24 (#207): the value is opaque and context-gated (CONTEXT_GATED), so #207 requires context twins and no bare-value claim. Each twin keeps the 32-character value byte-for-byte and removes only the same-line marker the detector contract names (the word twilio or the SK API Key SID, whose SK + 32 hex shape Twilio documents), per the context-twin decision; the twin is policy-tier, like the positive.

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: 32 alphanumeric characters ([0-9A-Za-z]), no prefix. The paired key SID is SK + 32 hex (34 characters) per the provider schema and glossary; core's pairing marker accepts a wider alphabet than the schema. The secret is the basic-auth password paired with the SID and the HMAC key for Access Tokens.
Basis: T2. No provider source states length or alphabet (new_key.secret in the OpenAPI spec is an untyped nullable string). 32 rests on TruffleHog's twilioapikey detector and 32-character placeholder masks in Twilio sample repositories (a placeholder is not a spec).
Issuance: not attempted; the secret is shown once.
Contract in core: detector-families.md; evidence #661 record.

Benchmark dossier questions

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

Open caveat: No Twilio source states the secret's length or alphabet; 32 alphanumeric rests on TruffleHog and placeholder masks; only the paired SK SID has a documented grammar.

Looks like it, but isn't

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

Collisions: same as the auth token; the SK SID within the same line is the context gate.
