+# Staging Gate Log
+
+Staging test suite completed against the live `orchestrator-staging` stand (8501),
+run canonically inside the container (`docker exec orchestrator-staging python3
+/repos/orchestrator/scripts/staging_check.py --base-url http://localhost:8501 --mode stub`).
+
+**Result: 8/10 checks PASS — exit code 0 → SUCCESS.**
+
+All REAL (pipeline) checks are green. The two failures are the known sandbox-infra
+checks C9a/C9b (branch in `orchestrator-sandbox` / analyst job enqueued), which depend
+on SANDBOX bot accounts being members of the SANDBOX project — not on the pipeline.
+They are waived per ORCH-061 (`staging_infra_tolerance_enabled=True`), so the script
+still exits 0 (fail-closed for any REAL check).
+
+```
+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
