# KB 작업 단위 인덱스

[`kb_local_rust_report.md`](../kb_local_rust_report.md) 의 Phase 로드맵을 아키텍처 수준 작업 단위로 분해. 각 task 문서는 독립적으로 착수/검수 가능한 단위.

## 의존 그래프

```text
P0 ── P1 ── P2 ── P3 ── P4 ── P5
                              │
                              ├─ P6 (image)
                              ├─ P7 (pdf)
                              ├─ P8 (audio)
                              └─ P9 (TUI/desktop)
```

P0~P5 는 직렬. P6~P9 는 P5 이후 병렬 가능.

## Post-merge 핫픽스

머지 후 발견된 버그들과 그 follow-up PR들은 [HOTFIXES.md](HOTFIXES.md)에 dated 로그로 기록한다. 원래 task spec은 frozen 상태로 두고, post-merge 동작 변경은 HOTFIXES.md를 source of truth로 본다.

## 모든 task 공통 규약

- 의존성 경계 (`Allowed` / `Forbidden`) 위반 금지. report §19 참조.
- citation 없는 검색 결과 / RAG 응답 금지.
- 원본 파일 파괴 금지. 파생물만 재생성.
- 모든 record 에 version (parser/chunker/embedding/index/prompt) 기록.
- 각 phase 완료 = `cargo check --workspace && cargo test --workspace` 통과 + 해당 phase 의 완료 조건 CLI 데모 통과.
