API credentials (polar_pat_, polar_at_, polar_rt_, polar_cs_, polar_crt_)

One of seven role prefixes + exactly 43 [A-Za-z0-9_-], the union of the pre-2025-01-02 URL-safe era and the alphanumeric-plus-checksum era.

Beta.12 arrival family polar-api-credential (#528, product redact-secret#1020), contract in benchmarks/lib/beta8/528b.ts from the #1014 handoff polar.md. T1 (provider server code, R1/R9). Shares the polar-token detector (finding type polar_api_credential). Neither pinned scanner has a Polar rule. Since the 4fb7882 re-pin (product PR #1039) it is an arrival family scored by that finding type (scanners/families.mjs arrivalFindingTypes), so the row maps to its own id.

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

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: one of seven role prefixes + exactly 43 [A-Za-z0-9_-], the union of the URL-safe era (before 2025-01-02) and the alphanumeric-plus-checksum era.
Basis: T1 under R1 and R9 from the provider server code and its commit history. No checksum applies: an era-1 body is all-alphanumeric about a quarter of the time.
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#1020, merged in redact-secret#1039 and is unreleased).

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

Collisions: polar_at_ without the u_/o_ sub-type is not a prefix; checkout polar_c_/polar_cl_ secrets are handed to the browser.
