+# Staging Gate Log
+
+Staging test suite completed against the live `orchestrator-staging` instance (8501).
+Result: **8/10 checks PASS**, exit code **0** → `staging_status: SUCCESS`.
+
+All REAL (pipeline) checks are green. The only two failures are the known
+sandbox-infra checks **C9a / C9b**, which depend on SANDBOX bot accounts being
+project members (infra precondition), not on the pipeline. Per ORCH-061 they are
+tolerated when every REAL check is green; the suite printed an `INFRA-WAIVED:` line
+and exited 0 (fail-closed for real checks preserved).
+
+## Execution
+
+- Command: `python3 /repos/orchestrator/scripts/staging_check.py --base-url http://localhost:8501 --mode stub`
+- Ran inside the `orchestrator-staging` container (canonical, ADR-001 / ORCH-048),
+  so the B6 registry-isolation check reads the running instance's own process-env.
+- Note: the `docker` CLI is not installed in this environment; the exec was issued
+  through the mounted Docker Engine API socket (`/var/run/docker.sock`), which is
+  functionally equivalent to `docker exec orchestrator-staging …`.
+
+## Observability — waiver line (ORCH-061)
+
+```
+INFRA-WAIVED: C9a Branch appears in orchestrator-sandbox, C9b Analyst job enqueued in staging queue (known sandbox-infra; real checks green)
+VERDICT: SUCCESS (exit 0) — SUCCESS (infra-waived): ['C9a Branch appears in orchestrator-sandbox', 'C9b Analyst job enqueued in staging queue'] are known sandbox-infra checks; all real checks green
+```
