flex-auth-user-engine is enforce on sha256:138aa347. Probe from
user-engine-8569d7cb87-fp7px: 200 with the projected token, 401 without,
403 when representing tenant-engine. Record fsGroup 10001 so uid 10001
can read the projected caller token.
IAM Profile v0.3 and Tenancy Posture v0.1 are now live on
policy.coulomb.social. Close the portal expansion workplan against those
documents, keep the flex-auth live A2 probe waiting, and forward optional
tenant_roles to flex-auth without authorizing from them locally.
Closes the caller side of FLEX-WP-0015. FlexAuthHTTPAdapter reads the
audience-scoped projected ServiceAccount token from a file on every decision,
so hourly rotation needs no restart, and runtime configuration now requires
USER_ENGINE_FLEX_AUTH_TOKEN_FILE.
A missing, empty, or unreadable token file fails closed as a denial without
reaching flex-auth: OSError joins the caught set and an empty read raises.
Coverage proves all three unusable-token cases deny before any request is
made, and that neither the deny reason nor the decision repr carries the
token value.
Tenant-authority reads now identify user-engine as actor `user-engine` under
the protected tenant.read action, keeping tenant ids opaque and URL-encoded.
Contract: docs/flex-auth-caller-identity.md. Full suite: 148 tests, 3
provider-gated skips.
