+# Staging Gate Log
+
+Staging test suite completed against the live staging environment
+(`orchestrator-staging`, 8501), run canonically 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
+```
+
+**Verdict: SUCCESS** (exit code 0).
+
+## Results
+
+Result: 8/10 checks PASS. All REAL (pipeline) checks are green:
+
+- **Block A (SMOKE)**: A1 `/health`, A2 `/queue`, A3 `ORCH_STAGING=true` — PASS
+- **Block B (ACCESS)**: B4 Plane sandbox, B5 Gitea sandbox (push=true), B6 registry
+  isolation (sandbox present, prod ET/ORCH absent) — PASS
+- **Block C (E2E, stub)**: C7 create issue in SANDBOX, C8 trigger pipeline via
+  `/webhook/plane` — PASS; C9a/C9b — waived sandbox-infra
+
+REAL failed: none.
+
+## Infra waiver (ORCH-061)
+
+The two failed checks are known sandbox-infra checks (C9a branch appears in
+`orchestrator-sandbox`, C9b analyst-job enqueued) — they depend on SANDBOX bot
+accounts being members of the sandbox Plane project, not on the pipeline. They
+were waived per ORCH-061 (`staging_infra_tolerance_enabled=True`); the script
+still exited 0 fail-closed because every REAL check is green.
+
+```
+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
+```
+
+Exit code remains the source of truth (fail-closed: any REAL failure still yields
+exit 1).
