+Milestone v1.1 (OpenClaude CLI Integration)이 2/3 완료.
+Phase 03 (CLI Build) + Phase 04 (Model Routing & Agent Loop) 완료.
+Phase 05 (VS Code Extension Packaging)는 아직 Plan 미작성 상태.
+</current_state>
+
+<completed_work>
+
+- Phase 03: CLI Build & Provider Connection - Done
+  - `bun install && bun run build` → OpenClaude v0.1.8 빌드 완료
+  - `.env` 프로바이더 설정 (http://192.168.10.4:8000/v1)
+  - `scripts/start_openclaude.bat` + `.ps1` 런처 생성
+  - `--print` 모드로 E2E 연결 검증: "Hello there, friend." (76 t/s)
+
+- Phase 04: Model Routing & Agent Loop - Done
+  - `~/.claude/settings.json` — agentModels + agentRouting 설정
+  - 핫스왑 테스트: fast(76 t/s) ↔ balanced(66 t/s) 왕복 성공
+  - 스트리밍 응답 + 장문 계산 (123*456=56,088) 검증 완료
+
+</completed_work>
+
+<remaining_work>
+
+- Phase 05: VS Code Extension Packaging (not started)
+  - Plan 작성 필요
+  - `npx @vscode/vsce package` → .vsix 빌드
+  - Machine B VS Code에 Extension 설치
+  - launchCommand + useOpenAIShim 설정 for Variet Engine
+
+</remaining_work>
+
+<decisions_made>
+
+- CLAUDE_CODE_USE_OPENAI=1 shim 사용 (llama-server /v1 호환)
+- Machine A IP = 192.168.10.4 (이더넷)
+- OPENAI_API_KEY = "variet-local" (llama-server는 키 검증 안 함)
+- agentRouting에 단일 모델(variet-fast)만 설정 — 핫스왑으로 tier 교체
+- --print 모드로 CLI 검증 (인터랙티브 도구 호출은 Extension에서 검증)
