Level-B CI Environment And Credential Operator Packet

Current truth: GITHUB_ENV_PRODUCTION_OWNER=OPERATOR_REQUIRED_UNVERIFIED; SECRET_MANAGER_FIX7_OWNER_CREDENTIAL=OPERATOR_REQUIRED_UNVERIFIED; IMPLEMENTATION_READINESS=BLOCKED; status FIX7_BLOCKED_LEVEL_B_PIPELINE_UNAVAILABLE.

Fixed resources: .github/workflows/fix7-level-b.yml; GitHub environment production-owner; runtime reference FIX7_PRODUCTION_OWNER_DSN; logical secret fix7-production-owner-dsn; manifest-approved workload identity; manifest-approved operator human reviewer; self-review prohibited.

infra-preflight immutable evidence must prove environment exists/right repo; required reviewer+prevent-self-review; exact workflow commit/source hash; secret metadata/version active without value; IAM only approved runner; redacted runtime fetch+DB auth; authenticated expected owner/migrator not Directus; fixed run.sh rejects alternate mode/packet. Missing resource is created only via approved operator infra process then reverified; T1 cannot create/approve/populate.

All live modes blocked until fresh evidence binds commit/environment/secret metadata/operator human/epoch. Secret never logged/stored. Extra IAM/environment bypass/stale/alternate credential/manual SQL => blocked. Rotation invalidates. Rollback disables access+secret version, revokes writer, fail-closed owner, increments epoch.
