Measured as the Beta.12 unscored arrival family gitlab-routable-personal-access-token (benchmarks/lib/beta8/1012c.ts; #1012 research, T1 provider code; the length holder and CRC are enforced as provider offline checks). The product reports it whole inside gitlab-token under the shared gitlab_token finding type (redact-secret#1022), so its findings carry no family evidence of their own and no detector is mapped here; the registry gitlab-token contract stays the legacy 20-byte body.

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 glpat-, a base64url payload with no padding (0-9a-zA-Z_-), then either . + 2-character base36 length + 7-character base36 CRC32 (unversioned), or . + 2-character base36 version + . + 2-character base36 length + 7-character base36 CRC32 (versioned). GitLab's rules bound the payload at 27 to 300 characters. The random part is 16 bytes, followed by a routing payload of newline-separated key:value pairs and a trailing length byte.

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.
