+# Staging Gate Log
+
+Staging test suite completed against the live staging stand (`orchestrator-staging`, port 8501).
+Canonical run inside the container (ORCH-048, ADR-001):
+
+```
+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**.
+
+- REAL failed: none
+- All REAL checks green: A1, A2, A3 (SMOKE), B4, B5, B6 (ACCESS), C7, C8 (E2E).
+- SANDBOX_INFRA failed (waived per ORCH-061): C9a, C9b — known sandbox-infra checks
+  that depend on SANDBOX bot accounts being members of the sandbox Plane project,
+  not on the pipeline.
+
+```
+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
+```
+
+Staging gate PASSED → advance.
