API key (wandb_v1_)
wandb_v1_ + [A-Za-z0-9_] to about 86 characters in all (86 in every provider fixture); the legacy 40-hex key stays with generic context.
Registry detector wandb-api-key since redact-secret#917 (registry pinned at 1127bf9); graduated from a Beta.11 arrival family (#436), contract in benchmarks/lib/beta8/436f.ts. T1 on the provider test constant (R5) and SDK validator (R1); length measured around 86 with no length asserted. trufflehog 3.97.4 registers only the keyword-gated legacy rule by default.

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
wandb_v1_, 86 characters in total (body 77), alphabet[A-Za-z0-9_]. Self-managed keys are<host>-<key>; the host label is outside the key. - Basis
- prefix T1 from a W&B-authored test constant (R5). Length T1 by example: the docs say "W&B now issues longer API keys (about 86 characters)", the SDK validator tests (wandb#10688) use 39, 40 and 86, and Weave fixtures use 86. Alphabet T1 from the SDK validator (
[\w-]+, dash only for the on-prem host prefix) and its error text (R1). Scanner rules add an internal underscore split (27 then 49), which is T2 and not required by the handoff. Re-checked 2026-09-28. - Issuance
- not attempted; recommended because of the "about" in the docs.
- Contract in core
- detector-families.md. That contract uses a tolerant 64 to 96 band around the documented width by an orchestrator decision on #917, wider than the handoff's exact 86; the handoff verdict here is unchanged.

Benchmark dossier questions
Things the sources do not settle. They are listed so nobody reads them as settled.
- Open caveat
- The docs say "about 86" characters; every provider test uses exactly 86, but a confirming issuance is recommended (does not block the contract).
Looks like it, but isn't
Values the dossier records as resembling this credential without being one.
- Collisions
- the legacy 40-hex key is SHA-1 and git-SHA shaped with no anchor; generic context already redacts it under
WANDB_API_KEY=. Internal client JWTs go to the JWT detector.
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.
| Scanner | Rule | What the rule matches |
