P0 — Workspace 뼈대 + 도메인 계약

목표

compile 되는 Rust 2024 workspace 와 domain spec 확정. 이후 모든 phase 가 이 계약 위에서 동작.

산출 crate

crate	역할
kebab-core	domain type, trait, error, ID 규칙
kebab-parse-types	parser 중간 표현 (ParsedBlock 등) — kebab-core 와 parsers/normalize 사이 thin layer (design §3.7b)
kebab-config	config 로딩, 기본값, 경로 확장
kebab-app	facade. CLI/TUI/desktop 공통 진입점
kebab-cli	kebab 바이너리 skeleton (--help만 동작)

Workspace 설정

Cargo.toml root:

[workspace]
resolver = "3"
members = ["crates/kebab-core", "crates/kebab-parse-types", "crates/kebab-config", "crates/kebab-app", "crates/kebab-cli"]

[workspace.package]
edition = "2024"
rust-version = "1.85"

[workspace.dependencies]
anyhow = "1"
thiserror = "2"
serde = { version = "1", features = ["derive"] }
serde_json = "1"
time = { version = "0.3", features = ["serde"] }
uuid = { version = "1", features = ["v7", "serde"] }
blake3 = "1"
tracing = "0.1"

추가 멤버 crate 는 후속 phase 에서 합류.

kebab-core 도메인 타입

RawAsset, CanonicalDocument, Block, Chunk, SearchHit, Citation, SourceSpan, Provenance, Metadata. report §6 정의 그대로.

kebab-core trait

pub trait SourceConnector { fn scan(&self, scope: &SourceScope) -> anyhow::Result<Vec<RawAsset>>; }
pub trait Extractor { fn supports(&self, m: &MediaType) -> bool; fn extract(&self, asset: &RawAsset, bytes: &[u8], ctx: &ExtractContext) -> anyhow::Result<CanonicalDocument>; }
pub trait Chunker { fn chunk(&self, doc: &CanonicalDocument, policy: &ChunkPolicy) -> anyhow::Result<Vec<Chunk>>; }
pub trait Embedder { fn model_id(&self) -> &str; fn dimensions(&self) -> usize; fn embed_texts(&self, inputs: &[EmbeddingInput]) -> anyhow::Result<Vec<Vec<f32>>>; }
pub trait Retriever { fn search(&self, query: &SearchQuery) -> anyhow::Result<Vec<SearchHit>>; }
pub trait LanguageModel { fn generate(&self, req: GenerateRequest) -> anyhow::Result<GenerateResponse>; }

초기엔 동기. async 도입은 LLM/embedding adapter 내부에 한정.

ID 규칙 (deterministic)

asset_id     = blake3(raw bytes)
doc_id       = stable source path + asset hash + parser version
block_id     = doc_id + block path + source span
chunk_id     = doc_id + chunker version + block ids
embedding_id = chunk_id + embedding model id + dimension
index_id     = collection name + index version + embedding model id

각 record 에 다음 version 필드 보존: doc_version, schema_version, parser_version, chunker_version, embedding_model, embedding_version, index_version, prompt_template_version.

kebab-app facade

CLI/TUI/desktop 모두 facade 함수 호출. parser/DB/LLM adapter 직접 호출 금지. 초기 facade 메서드 stub:

pub fn ingest(path: &Path) -> anyhow::Result<IngestReport>;
pub fn search(query: &str, mode: SearchMode) -> anyhow::Result<Vec<SearchHit>>;
pub fn ask(query: &str) -> anyhow::Result<Answer>;
pub fn inspect_doc(id: &DocumentId) -> anyhow::Result<CanonicalDocument>;
pub fn inspect_chunk(id: &ChunkId) -> anyhow::Result<Chunk>;
pub fn doctor() -> anyhow::Result<DoctorReport>;

kebab-cli skeleton

clap derive. subcommand: init, ingest, index, search, ask, inspect doc|chunk, doctor. 본체는 kebab-app 호출만. P0 에선 --help 만 동작.

spec 문서

docs/spec/ 에 다음 작성:

• domain-model.md
• ids.md
• canonical-document.md
• chunk-policy.md
• citation-policy.md
• module-boundaries.md
• ai-generation-guidelines.md

fixture

fixtures/markdown/ 에 최소 3개: simple-note.md, nested-headings.md, code-and-table.md.

의존성 경계

• kebab-core: 외부 의존 최소 (serde, time, uuid, blake3, thiserror, tracing).
• kebab-cli → kebab-app 만 의존. parser/DB/LLM 직접 의존 금지.
• kebab-app 은 trait 만 보고 동작. 구현체는 dyn injection.

완료 조건

• cargo check --workspace 통과
• cargo test --workspace 통과 (단위 테스트는 ID 생성/도메인 직렬화 round-trip)
• kebab --help 출력
• docs/spec/* 7개 문서 존재
• fixtures/markdown/* 3개 존재
• domain type serde JSON snapshot test 1개 이상

리스크 / 주의

• ID 규칙 변경은 모든 후속 phase 의 record 무효화. P0 에서 못 박을 것.
• async 남발 금지. 동기로 충분.
• crate 경계 침범 (특히 facade 우회) 1건이라도 들어오면 후속 phase 전체가 흔들림.
