+# Staging Gate Log
+
+Staging test suite completed against the live `orchestrator-staging` instance (port 8501).
+Run canonically **inside** the container via the Docker exec API (REST equivalent of
+`docker exec orchestrator-staging python3 /repos/orchestrator/scripts/staging_check.py
+--base-url http://localhost:8501 --mode stub`), so B6 reads the staging instance's own
+process-env registry (ORCH-048, ADR-001).
+
+**Exit code: 0 → advance.** All REAL pipeline checks passed (8/10 PASS).
+
+- 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): C7 create issue in SANDBOX, C8 trigger pipeline via /webhook/plane — PASS
+- C9a/C9b — FAILED but **waived** (known sandbox-infra checks; depend on SANDBOX bot
+  accounts being project members, not on the pipeline). Tolerated under ORCH-061 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
