+# Staging Gate Log — ORCH-042
+
+Staging test suite completed against the live staging environment
+(`orchestrator-staging`, port 8501). All checks passed.
+
+## Execution
+
+Canonical procedure (ORCH-048, ADR-001): run **inside** the
+`orchestrator-staging` container so the B6 registry-isolation check reads the
+registry from the running instance's own process-env (`.env.staging`).
+
+```
+docker exec orchestrator-staging \
+  python3 /repos/orchestrator/scripts/staging_check.py \
+  --base-url http://localhost:8501 --mode stub
+```
+
+(Executed via the Docker Engine API over the mounted unix socket, since no
+docker CLI is present in the agent environment; equivalent to the canonical
+`docker exec`.)
+
+**Exit code: 0 → staging_status: SUCCESS**
+
