flex-auth's flex-auth-ops-warden pin (FLEX-WP-0016) TokenReviews the caller and
binds resource.system: ops-warden to system:serviceaccount:ops-warden:ops-warden.
policy.py posted /v1/check with no Authorization header, so the pin logs
"caller authentication warning" and can only run callerAuth.mode: warn — which,
under ADHOC-2026-08-17-T01, is exactly what blocks policy.enabled: true.
- policy.caller_auth (none | file | env | command) + src/warden/caller_identity.py:
token resolved per call, never cached, written, or logged (ADR-0002)
- both check_sign_policy and check_fetch_policy attach the bearer header; an
unobtainable token fails closed rather than retrying anonymously
- scripts/check_policy_caller_identity.py: read-only gate, prints length and a
truncated fingerprint only, distinguishes 401 (audience/binding) from 403
- example config: caller_auth block, and flex_auth_url corrected — it pointed at
flex-auth.flex-auth.svc, a Service that does not exist
- WARDEN-WP-0031, PolicyGatedSigning caller-identity section and flip sequence
Default stays mode: none, so behaviour is unchanged until an operator opts in.
