# Project State

## Project Reference
A high-performance, locally-hosted AI assistant system built on two RTX 3060 12GB GPUs. It uses a "2+0" architecture where Machine A acts as a dedicated inference server running large language models, while Machine B handles the user interface (VS Code, Discord) and tool execution.

## Current Position
Phase: 02-api-engine (Complete) -> Ready for Phase 3
Plan: None
Status: Transitioning to Phase 3

## Progress
[████████████████████] 100% (Phase 01: LLM Tuning)
[████████████████████] 100% (Phase 02: API Engine)

## Completed Phases
- Phase 01 (LLM Tuning): 5개 모델 최적 설정 확정 (74.65 / 61.62 / 16.0 / 16.7 / 8.95 t/s)
- Phase 02 (API Engine): Variet Engine v1.0 — FastAPI 프록시 + 핫스왑 + 503 보호

## Recent Decisions
- 2+0 GPU Architecture (Machine A API Server, Machine B tools).
- 5-tier model strategy: fast/balanced/deep-coder/deep-logic/ultra.
- GPU 0 PCIe x4 제약 → 122B MoE는 GPU 1 단독 사용.
- Variet Engine: 단일 포트(8000) FastAPI 리버스 프록시.
- config/engine_models.json → 모든 설정의 Single Source of Truth.

## Pending Todos
0 pending.

## Blockers/Concerns
None.

## Next Phases (Suggested)
- Phase 03: VS Code Extension (에이전트 루프, 도구 통합)
- Phase 04: Discord Bot (개인 비서, 슬래시 명령어)
- Phase 05: MCP Tools (SearXNG, Calendar, Gmail)
