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
40 lowercase hex characters, no prefix. Datadog calls application keys legacy features after Q3 2026.
Basis
T2. The v1 spec's ApplicationKey.hash has length 40 (provider-domain, length only). Datadog-owned code (Agent, CloudFormation, ARM script) accepts [a-f0-9]{40} or the ddapp_ form, and a CloudFormation changelog names it "the legacy 40-character hex format". The Agent scrubber alone also accepts uppercase; core rejects it on purpose.
Issuance
not attempted.
Contract in core
detector-families.md; the record is the #645 evidence above and the corroboration entry datadog-application-key-legacy in benchmarks/support/empirical-observations.json.

Benchmark dossier questions

Things the sources do not settle. They are listed so nobody reads them as settled.
Open caveat
No identifying element exists: a bare 40-hex value fits a SHA-1 digest, so the shape is only claimed beside a same-line application-key or datadog marker.

Looks like it, but isn't

Values the dossier records as resembling this credential without being one.
Collisions
SHA-1 digests and Git commit ids have the same shape, so no bare-value claim is made.

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.
