+# Staging Gate Log
+
+Staging test suite completed. All checks passed (10/10).
+
+- Work item: ORCH-044
+- Repo: orchestrator (self-hosting → staging gate is real, not a no-op)
+- Container: `orchestrator-staging` (port 8501)
+- Command (canonical, ran INSIDE the container so B6 reads the instance's own `.env.staging` process-env):
+  `python3 /repos/orchestrator/scripts/staging_check.py --base-url http://localhost:8501 --mode stub`
+- Exit code: 0
+

+> Note: the host in this environment lacks the `docker` CLI, so the canonical
+> `docker exec orchestrator-staging ...` was performed via the Docker Engine API
+> over `/var/run/docker.sock` (Python stdlib, no host-env leakage). Semantics are
+> identical to `docker exec`: the script ran inside `orchestrator-staging` with
+> its own `.env.staging` process-env, keeping the B6 registry-isolation check valid.
