## Phase 19 Omni-Terminal (Wave 0-6 全部完成) ### 核心功能 - SSE 狀態機 (7-State 設計，10/10 分) - GenUI 動態渲染 (6 張卡片 + Zod Schema 驗證) - 核鑰 UX (長按授權 + 風險分級) - Terminal Telemetry (Sentry 整合) ### P0-P2 修復 - P0: Singleton → FastAPI Depends 依賴注入 - P1: Zod Schema 升級 (7 個驗證 Schema) - P1: 錯誤分類碼聚合 (Sentry fingerprint) - P2: Slow Query 監控 (5s 警告 / 10s 嚴重) ### 測試 - test_terminal_service.py: 54 項測試全通過 - 意圖分類: 42 個測試案例 (9 種 IntentType) ### 文檔 - ADR-031: SSE 架構實作紀錄 - ADR-032: GenUI 渲染實作紀錄 - Skills: v1.9 (後端 Terminal 章節) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
