Staging suite run inside orchestrator-staging via docker exec (canonical,
ADR-001). All 10/10 checks pass, exit 0. B6 now reads registry from the
running staging instance's own process-env -> sandbox present, prod ET/ORCH
absent, no false FAIL / spurious rollback.

Staging instance (8501) still runs a pre-ORCH-048 image without GET /projects,
so B6 deterministically FAILs (endpoint unavailable → no false PASS). Branch
code is correct; remediation is a host-side `--profile staging up -d --build`
of orchestrator-staging before re-running the gate.
