feat(adr-081): Phase 1 感官縱深 — 8D 情報蒐集 + 執行後驗證
成品: - IncidentEvidence DB model(8D 感官 + pre/post 執行狀態) - EvidenceSnapshot dataclass(build_summary → LLM 上下文) - SanitizationService(Prompt Injection 0-tolerance,12 pattern) - MCPToolRegistry(動態工具登記,suggest_tools 不寫死告警類型) - PreDecisionInvestigator(8D 並行感官,P99 < 8s,Redis 30s 快取) - PostExecutionVerifier(warmup 10s → 後狀態評估 success/degraded/failed) - decision_manager + approval_execution 接線(feature flag 守衛) Gate 1 修復:D4/D5/D7/D8 補 sanitize_dict_values;移除裸 "error" failure signal 防 error_rate key 誤判;evidence_snapshot rowcount 零行警告。 測試:130 passed(+111 新增) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

## 📍 2026-04-15 — AI 自主化飛輪 Phase 1 感官縱深建立
|
||||
|
||||
### 成品(ADR-081)
|
||||
|
||||
| 成品 | 路徑 | 說明 |
|
||||
|------|------|------|
|
||||
| DB Model | `apps/api/src/db/models.py` | IncidentEvidence 表(8D 感官 + 執行前後狀態 + 驗證結果) |
|
||||
| EvidenceSnapshot | `apps/api/src/services/evidence_snapshot.py` | 不可變快照,build_summary() 組裝 LLM 上下文 |
|
||||
| SanitizationService | `apps/api/src/services/sanitization_service.py` | Prompt Injection 0-tolerance(12 pattern)+ 敏感詞遮罩 |
|
||||
| MCPToolRegistry | `apps/api/src/services/mcp_tool_registry.py` | 動態工具登記冊,suggest_tools() 不寫死告警類型 |
|
||||
| PreDecisionInvestigator | `apps/api/src/services/pre_decision_investigator.py` | 8D 並行感官蒐集,P99 < 8s,Redis 30s 快取 |
|
||||
| PostExecutionVerifier | `apps/api/src/services/post_execution_verifier.py` | 執行後 K8s 收斂等待 + 三態評估(success/degraded/failed) |
|
||||
| decision_manager 接線 | `apps/api/src/services/decision_manager.py` | AIOPS_P1_PRE_DECISION_INVESTIGATOR flag 守衛 |
|
||||
| approval_execution 接線 | `apps/api/src/services/approval_execution.py` | AIOPS_P1_POST_EXECUTION_VERIFIER fire-and-forget |
|
||||
|
||||
### 測試覆蓋
|
||||
|
||||
| 測試檔 | 數量 |
|
||||
|--------|------|
|
||||
| test_sanitization_service.py | 28 |
|
||||
| test_mcp_tool_registry.py | 33 |
|
||||
| test_pre_decision_investigator.py | 28 |
|
||||
| test_post_execution_verifier.py | 22 |
|
||||
| **總計** | **111 新增(Phase 1),130 全數通過** |
|
||||
|
||||
### Gate 1 修復(4 項)
|
||||
|
||||
1. `evidence_snapshot.py`: rowcount < 1 → warning log(靜默零行更新)
|
||||
2. `post_execution_verifier.py`: 移除裸 `"error"` failure signal(防 error_rate key 誤判)
|
||||
3. `pre_decision_investigator.py`: D4/D5/D7/D8 補 sanitize_dict_values(Prompt Injection 0-tolerance)
|
||||
4. `feature_flags.py`: 補充 Pod 重啟才能 hot-reload flags 說明
|
||||
|
||||
### 下一步
|
||||
|
||||
- Phase 2: 5 Agent 骨架 + Orchestrator + AgentSession DB
