Compatibility aggregate (unreviewed Vercel token shapes)

Legacy benchmark routing for the runtime vercel-token detector; not a modern credential-family support claim.

Bounded by product #858 and benchmark #373. This row preserves the existing aggregate detector/fixture routing while runtime behavior and finding types remain unchanged. Its T0 profile cells combine five implementation hypotheses and must not be copied to, or read as evidence for, any modern Vercel credential family. Opaque unprefixed examples are also outside the modern positive contract.

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).

Open questions

vercel:access-token@1#candidate-source-wording-moved · raised 2026-10-03
The claim candidate-source cites vercel.com/docs/accounts/access-tokens (vercel-com-8ba2d5b3b4) for 'opaque format, not intended to be human-readable, prefixes per credential type'. Re-read 2026-10-03: that page now names only the vcp_ prefix and states no body length or alphabet; the opaque-format wording is on vercel.com/docs/sign-in-with-vercel/tokens (vercel-com-ee64691632) for access and refresh tokens only. The claim is left unedited (class unresolved); which page, if any, supports it needs a maintainer decision, and no provider page read states a body length or minimum length for any of the five prefixes.

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.

No format notes recorded

The provider dossier has no shape, basis or issuance note for this family, so nothing is stated about its format here.
