Enterprise organization key (sk-ant-api01-)

sk-ant-api01- prefixed key that Anthropic documents as a Compliance Access Key; the prefix is the general Claude Enterprise organization key for any scope set, so a finding must not claim 'compliance'.

Beta.10 arrival family anthropic-api01-key (#384, research redact-secret#776, product #862, #882). The product extends the shared anthropic-token detector; since product PR #882 (redact-secret#774) it reports its own anthropic_enterprise_api_key finding type (previously the shared anthropic_api_key type), so this family maps to no registry detector id but is scored on its own arrival id by finding type (scanners/families.mjs arrivalFindingTypes), never borrowing the status of anthropic:secret-api-key. T1 on the prefix only; the body is unspecified.

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).

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: prefix sk-ant-api01-, created in claude.ai Organization settings > API, shown once, does not expire on its own. The same prefix is used for any scope set (compliance, analytics, spend limits, members), so the value does not say "compliance" and scope is not encoded in it. Body length, alphabet and tail: no evidence. Do not extrapolate the api03 body.
Basis: T1 prefix on the provider documentation pages in the frontmatter; the staff help center article covers issuance and "shown once" only. No scanner rule handles api01. Third-party vendor pages that repeat the prefix are community evidence and disagree with the provider on where the key is created.
Issuance: needs a Claude Enterprise parent organization and its primary owner or an organization owner, with the Compliance API enabled. A standalone Console organization cannot create one. The structural-facts checklist is in the #776 discovery comment.
Contract in core: detector-families.md. Whether the finding type should say "compliance" or "Enterprise" was a product decision raised in #776 and settled by #882: sk-ant-api01- keys get their own type, anthropic_enterprise_api_key, named for the general Enterprise scope and deliberately not "compliance" (#776 disposition).

Benchmark dossier questions

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

Open caveat: Body length, alphabet and tail are unmeasured for this prefix; needs one issued Enterprise key (checklist in #776).

Looks like it, but isn't

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

Collisions: sk-ant-api03- (Console Claude API key) and sk-ant-admin01- (admin key) differ only in the prefix segment and are distinct credential classes. Enterprise api01 keys are also a documented confusable in third-party integration guides, which reject the wrong type.

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.
