P3.1-T1 接線測試（補 commit 123d9c8a 的 dedicated tests）：
- model_rollback_service.check() 在 offline_replay 後被呼叫
- resource_resolver.resolve() 在 approval_execution 解析 kubectl 後被呼叫
- exception fail-soft 路徑驗證
- RESOURCE_RESOLVE_TOTAL counter 各 label
Tests: 12 passed

P3.1-T1 Tier-1 三服務整合測試
|
||
==============================
|
||
測試 rollback_manager / model_rollback_service / resource_resolver
|
||
整合到主流程後：
|
||
1. 觸發驗證 (mock 服務後確認 .trigger() / .check() / .resolve() 被呼叫)
|
||
2. exception 完全隔離（服務拋例外不阻斷主流程）
|
||
3. metric counter 被正確 .inc()
