+# Staging Gate Log
+
+> Машинный вердикт читается ТОЛЬКО из `staging_status:` во frontmatter. `SUCCESS` → дальше; `FAILED` → откат.
+
+Staging test suite завершён против живого стенда `orchestrator-staging` (8501). Запуск канонический —
+`docker exec orchestrator-staging python3 /repos/orchestrator/scripts/staging_check.py --base-url http://localhost:8501 --mode stub`
+(ORCH-048, ADR-001). Скрипт завершился с **exit code 0** → `staging_status: SUCCESS`.
+
+Итог: **8/10 checks PASS**. Все REAL-проверки зелёные; два FAIL — известные sandbox-infra-проверки
+(C9a/C9b), waived согласно ORCH-061 (зависят от членства SANDBOX bot-аккаунтов в проекте, не от
+конвейера). Exit-code → вердикт не меняется: trust the exit code, REAL failed = none.
+
+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
+
+## Results
+- **Block A (SMOKE)**: PASS — A1 `/health` → 200 `status=ok`; A2 `/queue` → 200 с counts/max_concurrency/resilience; A3 `ORCH_STAGING=true` (не прод).
+- **Block B (ACCESS)**: PASS — B4 Plane sandbox доступен (5 projects, sandbox=YES); B5 Gitea `orchestrator-sandbox` доступен, push=true; B6 Registry изолирован (sandbox present, prod ET/ORCH absent).
+- **Block C (E2E, mode=stub)**: C7 создать issue в Plane SANDBOX → PASS; C8 триггер конвейера `/webhook/plane` → PASS; C9a (branch в sandbox) и C9b (analyst job в очереди) → FAIL, **INFRA-WAIVED** (sandbox bot-accounts не члены проекта). Cleanup: Plane issue удалён (HTTP 204).
+
+REAL failed: none.
