Beta.12 arrival family vercel-personal-access-token scored by finding type (benchmarks/lib/beta8/1012e.ts; #1013 record, T2: vcp_ + exactly 56 [A-Za-z0-9]). Product redact-secret#1036 types it inside the shared vercel-token detector under its own finding type, recorded in scanners/families.mjs arrivalFindingTypes. The base62 CRC-32 suffix is unresolved and never enforced; the vercel:access-token aggregate measurement is not attributed to this family.

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
vcp_ plus 56 characters. Marker from the Access tokens guide ("Personal access tokens begin with the prefix vcp_") and the changelog. Length from the CLI global options page (--token and VERCEL_TOKEN examples; page last updated 2026-05-28) and three peer rules.
Contract in core
detector-families.md. Since product #1036 (PR #1039, merged to main, unreleased) vcp_ + exactly 56 [A-Za-z0-9] is reported as its own finding type at T2, and #1042 (PR #1045) exempts the listed one-character-run placeholders. vci_ and vck_ stay under the unqualified vercel_token compatibility type until ruling Q-VC.

In run order. Counts are what each scanner recorded on this family's fixtures, whichever rules it has; a scanner with no rule for the family has nothing to report on it.

Looks like it, but isn't

Values the dossier records as resembling this credential without being one.
Collisions
deployment, project, team, integration and client ids are sibling identifiers; an unprefixed 24-character value is not a valid positive or negative on width alone. Team- and project-scoped vcp_ tokens exist next to full-account ones, so the marker does not imply scope.

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.

No peer rule maps to this family

None of the reviewed peer scanners has a rule that can match a credential of this family.
