+# Staging Gate Log
+
+Staging test suite completed. Exit code 0 → advance.
+
+Canonical run (ORCH-048, ADR-001) inside the live staging container:
+
+```
+docker exec orchestrator-staging \
+  python3 /repos/orchestrator/scripts/staging_check.py \
+  --base-url http://localhost:8501 --mode stub
+```
+
+## Result: 8/10 checks PASS
+
+- **Block A (SMOKE):** A1 /health, A2 /queue, A3 ORCH_STAGING=true — all PASS.
+- **Block B (ACCESS):** B4 Plane sandbox (R), B5 Gitea orchestrator-sandbox (R+push), B6 registry isolation (sandbox present, prod ET/ORCH absent) — all PASS.
+- **Block C (E2E, stub):** C7 create issue, C8 trigger pipeline — PASS.
+
+REAL failed: **none** — all pipeline checks green.
+
+## INFRA-WAIVED (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
+```
+
+C9a/C9b are the two known sandbox-infra-only checks (depend on SANDBOX bot accounts being members of the sandbox Plane project, not on the pipeline). They are tolerated because every REAL check is green; the script printed `INFRA-WAIVED:` and exited 0 (fail-closed semantics preserved: any REAL failure would still yield exit 1).
