chore: bump version 0.8.0 → 0.8.1

dogfood-discovered code_lang/repo filter bug (PR #144) fix lands in
production. patch bump because:
- 1A-1 advertised CLI flags --code-lang / --repo were live but inert
  (SearchFilters fields propagated but never applied to retriever SQL)
- fix restores intended behavior; no new wire surface
- user has dogfooded against httpx + zod + lodash and re-validating
  needs the fixed binary

 `-j 1` for the full workspace test isn't optional: 18 integration-test binaries each link `lance` + `datafusion` + `arrow` + `tantivy` and the parallel link step exhausts memory (linker gets SIGKILL'd, build silently fails partway). Per-crate runs are fine in parallel.
 
-`target/` is 6–10 GB after a fresh build (DataFusion + Lance + fastembed + 18 × test-binary debug info). The dev/test profile is already trimmed (`debug = "line-tables-only"`, `split-debuginfo = "unpacked"` — see workspace `Cargo.toml`). Run `cargo clean` after phase merges if disk pressure shows up; backtraces still resolve to function + line.
+`target/` is 6–10 GB after a fresh build but **balloons to 90+ GB after a few task cycles** (each fb-* batch adds incremental compile artifacts on top of the existing 18 × test-binary debug info). The dev/test profile is already trimmed (`debug = "line-tables-only"`, `split-debuginfo = "unpacked"` — see workspace `Cargo.toml`). Run `cargo clean` **routinely after each merged PR**, not just "if pressure shows up" — disk space is tight and recovery via `cargo clean` is cheap (one re-link per crate on next build). Verified pattern: 92 GB → 0 GB in seconds, backtraces still resolve to function + line.

+//! `kebab-parse-code::javascript` — tree-sitter JavaScript / JSX AST
+//! extractor (P10-1B Task K).
+//!
+//! Implements [`kebab_core::Extractor`] for [`MediaType::Code("javascript")`].
+//! Walks the tree-sitter parse tree (single grammar
+//! [`tree_sitter_javascript::LANGUAGE`] — the JS grammar handles `.jsx`
+//! as well, no second grammar needed) and emits one [`Block::Code`] per
+//! top-level AST semantic unit (free fn, class, each method,
+//! recursively per nested class), each carrying [`SourceSpan::Code`]
+//! with the unit's dotted symbol path prefixed by
+//! [`module_path_for_tsjs`].
+//!
+//! Glue declarations (`import_statement`, bare `export_statement`
+//! re-exports, `lexical_declaration` / `variable_declaration` at the
+//! module level, etc.) collapse into one grouped `<top-level>` (or
+//! `<module>`) unit.
+//!
+//! `export_statement` is unwrapped: an `export function|class` is
+//! treated as the inner declaration arm but the unit's line range
+//! comes from the OUTER `export_statement` so the `export ` prefix is
+//! folded in. `export default function () {}` / `export default class
+//! {}` (no `name` field) emits `default` as the symbol name.
+//!
+//! Differs from `typescript.rs` only by: single-grammar (no
+//! TS/TSX selection) and no `interface_declaration` /
+//! `type_alias_declaration` / `enum_declaration` arms (TS-only). All
+//! other walker behavior (export unwrap with `value`-field quirk for
+//! default-exported anonymous function/class, class-body method walk,
+//! glue flush, post-pass `<module>` → `<top-level>` rewrite) is
+//! identical.
+//!
+//! Scope follows 1A-2 / 1B Task K: AST unit extraction + dotted symbol
+//! paths + line ranges. Per design §3.4 / §9.1 / §9 versioning.

+//!
+//! Implements [`kebab_core::Extractor`] for [`MediaType::Code("rust")`].
+//! Walks the tree-sitter parse tree and emits one [`Block::Code`] per
+//! top-level AST semantic unit (free fn, type, trait, macro, each impl
+//! method, recursively per module), each carrying [`SourceSpan::Code`]
+//! with the unit's self-reference symbol path (design §3.4). Glue
+//! declarations (`use` / `const` / `static` / bodyless `mod` / top-level
+//! attributes / macro invocations) collapse into one grouped
+//! `<top-level>` (or `<module>`) unit.
+//!
+//! Doc comments and attributes immediately preceding an item are folded
+//! into that item's line range (design §9.1 "선언 + doc comment").
+//!
+//! Scope is intentionally narrow: AST unit extraction + symbol paths +
+//! line ranges for Rust. The `CanonicalDocument` scaffold mirrors
+//! `kebab-parse-pdf`. Per design §3.4 / §9.1 / §9 versioning.
+//!
+//! Edge cases: a Rust file consisting solely of comments / whitespace
+//! (no fn / type / impl / mod / glue items) yields zero blocks → zero
+//! chunks → not surfaced in search. Safe (no panic) and consistent with
+//! "an empty page produces no chunks" in `pdf-page-v1`.

+# p10-1B Python + TS/JS AST Chunkers Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development to implement this plan task-by-task.
+
+**Goal:** Activate Python / TypeScript / JavaScript code ingest end-to-end on top of 1A-2's infrastructure — 3 new tree-sitter grammars, 3 new Extractors, 3 new chunkers (`code-{python,ts,js}-ast-v1`), a `module_path_for_*` helper for workspace-path → module-path conversion, and a small app-dispatch generalization. Wire `code_lang` filter / breakdown / Citation::Code surface activate automatically.
+
+**Architecture:** Mirror 1A-2 exactly per language. Each Extractor in `kebab-parse-code/src/{python,typescript,javascript}.rs` calls its tree-sitter grammar and emits one `Block::Code` per top-level AST semantic unit with `SourceSpan::Code { line_start, line_end, symbol, lang }`. Symbol = `module_path` (from workspace_path) `+` per-language join (`.` for Python, `/.../basename.symbol` for TS/JS). Each chunker is a near-duplicate of `code-rust-ast-v1` (1:1 + oversize split). App dispatch becomes `match lang { "rust" | "python" | "typescript" | "javascript" }`.
+
+**Tech Stack:** Rust 2024 workspace, `tree-sitter` 0.26, `tree-sitter-python` / `tree-sitter-typescript` / `tree-sitter-javascript`, existing 1A-2 infrastructure (citation_helper Code arm, backfill, schema breakdown).
+
+**Memory note:** Host was OOM-killed earlier in this branch's history. Prefer `cargo test -p <crate>` and `cargo check -p <crate>`; the only `cargo test --workspace -j 1` call is the Task L full-suite gate. Never run cargo invocations in parallel.
+
+---
+
+## Pre-flight
+
+Branch `feat/p10-1b-py-ts-js` already exists on main (`git checkout feat/p10-1b-py-ts-js`).
+
+- [ ] **Disk hygiene**: `cargo clean`.
+
+Reference files (read before touching the corresponding 1B file):
+- 1A-2 Rust extractor: `crates/kebab-parse-code/src/rust.rs` — the scaffold every per-lang extractor mirrors.
+- 1A-2 Rust chunker: `crates/kebab-chunk/src/code_rust_ast_v1.rs` — the scaffold every per-lang chunker mirrors.
+- 1A-2 app dispatch: `crates/kebab-app/src/lib.rs` `ingest_one_code_asset` (~line 1645).
+- 1A-2 source-fs routing: `crates/kebab-source-fs/src/media.rs:39` (the `"rs" =>` arm).
+- 1A-2 lang dispatch: `crates/kebab-parse-code/src/lang.rs::code_lang_for_path`.
+
+---
+
+## Task A: Workspace deps
+
+**Files:**
+- Modify: `Cargo.toml` (workspace `[workspace.dependencies]`, after the existing `tree-sitter-rust` entry)
+- Modify: `crates/kebab-parse-code/Cargo.toml` (`[dependencies]`)
+
+- [ ] **Step 1**: Resolve versions: `cargo add tree-sitter-python tree-sitter-typescript tree-sitter-javascript -p kebab-parse-code`.
+
+- [ ] **Step 2**: Lift the three resolved versions into `[workspace.dependencies]` in the root `Cargo.toml`, immediately after the `tree-sitter-rust` line. Single-line comment first:
+
+```toml
+# Python / TS / JS grammars for code ingest (kebab-parse-code, p10-1B).
+tree-sitter-python     = "<resolved>"
+tree-sitter-typescript = "<resolved>"
+tree-sitter-javascript = "<resolved>"
+```
+
+Then change the crate's `[dependencies]` entries to `{ workspace = true }` matching the existing `tree-sitter` / `tree-sitter-rust` style.
+
+- [ ] **Step 3**: `cargo build -p kebab-parse-code` → clean (unused deps OK; warnings appear when actually imported in later tasks).
+
+- [ ] **Step 4**: Commit.
+
+```bash
+git add Cargo.toml Cargo.lock crates/kebab-parse-code/Cargo.toml
+git commit -m "build(p10-1b): add tree-sitter-python/-typescript/-javascript workspace deps
+
+Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>"
+```
+
+---
+
+## Task B: source-fs media routing for `.py`/`.pyi`/`.ts`/`.tsx`/`.js`/`.mjs`/`.cjs`/`.jsx`
+
+**Files:**
+- Modify: `crates/kebab-source-fs/src/media.rs` (add 3 arms next to the existing `"rs"` arm at L39)
+- Test: same file's test module
+
+- [ ] **Step 1 (failing test)**:
+
+```rust
+#[test]
+fn py_ts_js_files_map_to_media_code() {
+    assert_eq!(media_type_for(Path::new("a/b.py")),    MediaType::Code("python".into()));
+    assert_eq!(media_type_for(Path::new("a/b.pyi")),   MediaType::Code("python".into()));
+    assert_eq!(media_type_for(Path::new("a/b.ts")),    MediaType::Code("typescript".into()));
+    assert_eq!(media_type_for(Path::new("a/b.tsx")),   MediaType::Code("typescript".into()));
+    assert_eq!(media_type_for(Path::new("a/b.js")),    MediaType::Code("javascript".into()));
+    assert_eq!(media_type_for(Path::new("a/b.mjs")),   MediaType::Code("javascript".into()));
+    assert_eq!(media_type_for(Path::new("a/b.cjs")),   MediaType::Code("javascript".into()));
+    assert_eq!(media_type_for(Path::new("a/b.jsx")),   MediaType::Code("javascript".into()));
+    // Rust 1A-2 arm still works
+    assert_eq!(media_type_for(Path::new("a/b.rs")),    MediaType::Code("rust".into()));
+}
+```
+
+- [ ] **Step 2**: Run → FAIL.
+
+- [ ] **Step 3**: Add the three arms before the `_ => MediaType::Other(ext)` fallback. Match existing style and order extensions logically (most common first within each language):
+
+```rust
+        // p10-1B: Python / TS / JS AST chunkers active.
+        "py" | "pyi"               => MediaType::Code("python".into()),
+        "ts" | "tsx"               => MediaType::Code("typescript".into()),
+        "js" | "mjs" | "cjs" | "jsx" => MediaType::Code("javascript".into()),
+```
+
+- [ ] **Step 4**: Run → PASS. Then `cargo test -p kebab-source-fs` → no regression.
+
+- [ ] **Step 5**: `cargo clippy -p kebab-source-fs --all-targets -- -D warnings` clean. Commit.
+
+```bash
+git add crates/kebab-source-fs/
+git commit -m "feat(p10-1b): route .py/.pyi/.ts/.tsx/.js/.mjs/.cjs/.jsx to MediaType::Code
+
+Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>"
+```
+
+---
+
+## Task C: `module_path_for_python` + `module_path_for_tsjs` helpers
+
+**Files:**
+- Modify: `crates/kebab-parse-code/src/lang.rs` (add 2 pub fns + tests)
+- Modify: `crates/kebab-parse-code/src/lib.rs` (re-export the 2 fns)
+
+These convert a `WorkspacePath` into a module-path prefix for symbol formatting. Single source of truth — used by all per-language extractors.
+
+### Rules
+
+**`module_path_for_python(workspace_path: &str) -> String`**:
+1. Strip a leading well-known "source root" prefix from a small allowlist if present (in order): `crates/<name>/src/`, `src/`, `lib/`. (Use a single small `for` loop over the allowlist; stop at first prefix match.) Rationale: avoid noisy `crates.x.src.foo.bar` symbols when the user has a conventional layout, while leaving non-conventional paths untouched.
+2. Strip trailing `.py` or `.pyi` extension. If the basename (after extension strip) is `__init__`, drop it (and the preceding `/`) so `pkg/__init__.py` → `pkg`.
+3. Replace `/` with `.`.
+4. Result is the dotted module prefix. Symbols are joined with `.` (e.g. `module_path + "." + sym`). Empty result (file is at workspace root without prefix) → use empty string → symbol is the unit name alone.
+
+**`module_path_for_tsjs(workspace_path: &str) -> String`**:
+1. Strip extension if it's one of `.ts` / `.tsx` / `.js` / `.jsx` / `.mjs` / `.cjs`.
+2. Do NOT replace `/` (TS/JS convention is path-like). Do NOT strip any source root (TS/JS layouts vary too widely).
+3. Result is the path-style prefix (e.g. `src/search/retriever/Retriever`). Symbols join with `.` (`prefix + "." + sym`, e.g. `src/search/retriever/Retriever.search`).
+
+- [ ] **Step 1 (failing tests)** — add to existing `mod tests` (or create one) in `lang.rs`:
+
+```rust

+```
+
+- [ ] **Step 2**: Run → FAIL (helpers not defined).
+
+- [ ] **Step 3**: Implement both in `lang.rs`. Suggested implementation (refine if a test points out a missed edge case):
+
+```rust

+/// See plan §Task C for the exact rules.
+pub fn module_path_for_python(workspace_path: &str) -> String {
+    let mut p: &str = workspace_path;
+    // Strip a known source-root prefix. Allowlist + `starts_with` over a

+        }
+    }
+    p.to_string()
+}
+```
+
+- [ ] **Step 4**: Re-export both from `lib.rs` (next to the existing `pub use lang::code_lang_for_path`):
+
+```rust
+pub use lang::{code_lang_for_path, module_path_for_python, module_path_for_tsjs};

+
+## Task D: App dispatch generalization
+
+**Files:**
+- Modify: `crates/kebab-app/src/lib.rs`
+
+Today's `ingest_one_code_asset` (~L1645) hardcodes `RustAstExtractor` + `CodeRustAstV1Chunker`. 1B needs to dispatch by `lang`. Cleanest minimal change: keep the same function signature but take `code_lang: &str` and `match` it internally onto an `Extractor` + `Chunker` pair. Rust path keeps the same observable behavior.
+
+Two equivalent dispatch shapes — pick the one with the smallest diff:
+
+**Shape 1 (recommended — fewest lines changed):** factor extractor invocation + chunker invocation into a small `match code_lang` *inside* `ingest_one_code_asset`. The `parser_version` constant lookup also branches. Everything else (read bytes, ExtractContext, put_*, embed, IngestItem) stays a single non-branched flow.
+
+**Shape 2:** introduce a tiny enum `CodeLangKind { Rust, Python, Typescript, Javascript }` + an `impl CodeLangKind { fn extract(...) -> CanonicalDocument; fn chunk(...) -> Vec<Chunk>; fn parser_version() -> ParserVersion; fn chunker_version() -> ChunkerVersion; }`. More structure, but better insulates the function body.
+
+Use Shape 1 for this task (less risk). A future C/D phase can refactor to Shape 2 if the dispatch grows.
+
+- [ ] **Step 1 (failing test)** — add a Python smoke as the failing test (TS/JS land later in this PR; one failing-then-passing TDD cycle is enough to lock the dispatch contract):
+
+In `crates/kebab-app/tests/code_ingest_smoke.rs` add:
+
+```rust
+#[test]
+fn python_file_ingests_and_searches_as_code_citation() {
+    // Mirror rust_file_ingests_and_searches_as_code_citation exactly,
+    // but write `kebab_eval/metrics.py` (in the temp workspace root) with:
+    //     def compute_mrr(): return 1.0
+    // and assert h.code_lang == Some("python"), citation.lang == Some("python"),
+    // citation.symbol == Some("kebab_eval.metrics.compute_mrr"), parser_version "code-python-v1",
+    // chunker_version "code-python-ast-v1".
+    // ...
+}
+```
+
+(Spec shape ONLY — the actual extractor + chunker land in Tasks F + G. This test compiles but FAILS at runtime until those land. Mark it `#[ignore]` if it would otherwise break TDD ordering — un-`#[ignore]` it in Task G's commit. Alternative: skip this step here and rely on the per-extractor unit tests in Task F + Task G; that is the cleaner TDD ordering. Choose either; document the choice in the commit message.)
+
+- [ ] **Step 2**: Update `ingest_one_asset` dispatch match arm to accept all four code languages with a `lang` capture passed through:
+
+```rust
+        // p10-1A-2 / 1B: code ingest dispatch.
+        MediaType::Code(lang)
+            if matches!(lang.as_str(), "rust" | "python" | "typescript" | "javascript") =>
+        {
+            return ingest_one_code_asset(
+                app, asset, chunk_policy, embedder, vector_store,
+                existing_doc_ids, force_reingest, lang.as_str(),
+            );
+        }
+```
+
+(Keep the trailing `MediaType::Code(_) | MediaType::Audio(_) | MediaType::Other(_)` or-pattern as the Skipped fallback — non-allowlisted code langs route there.)
+
+- [ ] **Step 3**: Update `ingest_one_code_asset` signature to take `code_lang: &str` and dispatch internally. Keep all I/O / persistence / embed code unchanged. Per the Shape-1 recipe:
+  - `let parser_version = match code_lang { "rust" => ParserVersion(kebab_parse_code::RUST_PARSER_VERSION.into()), "python" => ParserVersion(kebab_parse_code::PYTHON_PARSER_VERSION.into()), "typescript" => ParserVersion(kebab_parse_code::TS_PARSER_VERSION.into()), "javascript" => ParserVersion(kebab_parse_code::JS_PARSER_VERSION.into()), _ => unreachable!(), };`
+  - The `try_skip_unchanged` call's chunker_version arg branches the same way (different chunker per lang).
+  - The extract call branches: `match code_lang { "rust" => RustAstExtractor::new().extract(...), "python" => PythonAstExtractor::new().extract(...), ... }`.
+  - The chunk call branches: `match code_lang { "rust" => CodeRustAstV1Chunker.chunk(...), "python" => CodePythonAstV1Chunker.chunk(...), ... }`.
+  - All other lines (purge_vector_orphans / put_asset_with_bytes / put_document / put_blocks / put_chunks / embed branch / IngestItem) unchanged.
+
+At this point Python/TS/JS extractors + chunkers don't exist yet → compile FAILS on the references. Acceptable — Task E/F/G/H/I add them. To stage compile-cleanly: gate the Python/TS/JS arms behind `unimplemented!()` for now (returns an error path) and let Tasks F/G/H/I/J/K replace them. Recommended: leave the dispatch fully written but use `anyhow::bail!("not yet activated in this commit")` for the three non-Rust arms, with a `TODO(p10-1b Task X)` comment per arm. They flip to real calls when each language's extractor + chunker land.
+
+- [ ] **Step 4**: `cargo test -p kebab-app --lib` (lib-only is enough — integration tests for the non-Rust paths land later). Existing Rust path tests must stay green.
+
+- [ ] **Step 5**: clippy clean, commit.
+
+```bash
+git add crates/kebab-app/
+git commit -m "refactor(p10-1b): generalize ingest_one_code_asset for multi-language dispatch
+
+Rust path unchanged (verified by existing code_ingest_smoke tests). Python/TS/JS arms
+bail with TODO; per-lang extractor + chunker land in subsequent tasks.

+## Task E: Python Extractor (`kebab-parse-code/src/python.rs`)
+
+**Files:**
+- Create: `crates/kebab-parse-code/src/python.rs`
+- Modify: `crates/kebab-parse-code/src/lib.rs` (`pub mod python` + re-exports `PYTHON_PARSER_VERSION` and `PythonAstExtractor`)
+- Create: `crates/kebab-parse-code/tests/fixtures/sample.py`
+
+Scaffold MIRRORS `crates/kebab-parse-code/src/rust.rs` line-for-line (read it first). Only the AST walk + the symbol prefix differ.
+
+### Python AST mapping
+
+tree-sitter-python language: `tree_sitter_python::LANGUAGE` (LanguageFn). Set via `parser.set_language(&tree_sitter_python::LANGUAGE.into())`.
+
+Walk `module` (root) named children. Maintain `mod_path: Vec<String>` — but for Python we DO NOT push class names onto `mod_path` (class members get `Class.method` form via the class arm directly; nested classes recurse with the class name appended).
+
+| node kind | unit | symbol (joined with `.`) |
+|-----------|------|--------------------------|
+| `function_definition` (name field) | 1 | `<module_prefix>.<fn_name>` (or `<fn_name>` if module_prefix empty) |
+| `class_definition` (name) — emit ONE unit for the class definition itself (symbol `<module_prefix>.<ClassName>`), then recurse into its `block` body: each inner `function_definition` → unit with symbol `<module_prefix>.<ClassName>.<method_name>`; nested `class_definition` recurses with parent class prepended. | 1 per class + 1 per method (etc.) | as above |
+| `decorated_definition` | unwrap — process its inner `definition` (either function_definition or class_definition) as if at the same level. `unit_start`'s backward extension over `decorator` siblings folds them into the unit. | n/a | n/a |
+| `import_statement`, `import_from_statement`, `expression_statement`, `assignment`, `global_statement`, `future_import_statement` at module level | glue | `<top-level>` (with `module_prefix` prefix if non-empty: `<module_prefix>.<top-level>`) |
+
+`unit_start` (backward extension) covers `comment` siblings + `decorator` siblings (decorators in tree-sitter-python appear as children of `decorated_definition`, NOT as siblings — so the `unwrap decorated_definition` arm above is what brings them in; `comment` siblings still need backward extension). Adapt `unit_start` for the Python flavor: extend over `comment` siblings only (decorators are already covered by unwrapping `decorated_definition`).
+
+Module-prefix application: at extract time, compute `let mod_prefix = kebab_parse_code::module_path_for_python(&asset.workspace_path.0);`. The walk builds symbols using `mod_prefix` (joined with `.` if non-empty; the bare name if empty). Glue group: if `mod_prefix` non-empty, symbol = `format!("{mod_prefix}.<top-level>")`; else `<top-level>`. `<module>` glue label (file contains only `import`s and no real unit) follows the same prefix rule.
+
+### Scaffold differences from rust.rs
+
+- `pub const PARSER_VERSION: &str = "code-python-v1";`
+- `pub struct PythonAstExtractor;` + `new()`/`Default`.
+- `fn supports(&self, m: &MediaType) -> bool { matches!(m, MediaType::Code(l) if l == "python") }`
+- Agent string `"kb-parse-code"` (unchanged).
+- `metadata.code_lang = Some("python".to_string())`.
+- `repo` / `git_branch` / `git_commit` from `crate::repo::detect_repo` (same as Rust).
+- The AST walk is its own `build_blocks` function — DO NOT generalize across languages in this task (each grammar's node names differ enough that polymorphism hurts more than helps; a future refactor task can extract common helpers if patterns converge).
+
+### Step list (TDD)
+
+- [ ] **Step 1**: Create `tests/fixtures/sample.py`:
+
+```python
+"""sample fixture."""
+import os
+
+ANSWER = 42
+
+@staticmethod
+def free(x):
+    """free fn."""
+    return x + 1
+
+class Foo:

+    def double(self, n):
+        return n * 2

+    }
+}
+```
+
+(`tests_support::fixed_code_asset` — promote 1A-2's `fixed_rust_asset` to a generic helper that takes the lang string and sets `media_type: MediaType::Code(lang.to_string())`. Move it to a new `pub(crate) mod tests_support` in `rust.rs` so it's reachable from `python.rs::tests`, OR duplicate it inline — pick the smaller diff. Keep the helper `#[cfg(test)]`.)
+
+- [ ] **Step 3**: Run → FAIL (`PythonAstExtractor` undefined).
+
+- [ ] **Step 4**: Implement `python.rs`. Scaffold mirrors `rust.rs`; the AST walk follows the table above. The `mod_path: Vec<String>` for Python tracks **class nesting** (so methods get `Class.method`, nested classes get `Outer.Inner`). `Vec` empty at function-level. Glue grouping mirrors Rust's. Apply `mod_prefix` from `module_path_for_python(&asset.workspace_path.0)` to all unit symbols: `if mod_prefix.is_empty() { sym } else { format!("{mod_prefix}.{sym}") }`. The `<top-level>` / `<module>` label inherits the same prefixing.

+- The validation message says "code-python-ast-v1 only handles..."
+
+`split_oversize` + `make_chunk` + `AST_CHUNK_MAX_LINES` + `BYTES_PER_TOKEN` + `POLICY_HASH_HEX_LEN` IDENTICAL (these are language-agnostic).
+
+- [ ] **Step 1 (failing tests)**: Copy the entire `#[cfg(test)] mod tests` from `code_rust_ast_v1.rs` and substitute `Rust` → `Python` / `code-rust-ast-v1` → `code-python-ast-v1`. Use the same in-memory `code_doc` helper — it doesn't care about the actual language. Add one extra test specifically asserting the `policy_hash` equals the Rust chunker's (cross-chunker fingerprint identity is a 1A-2 invariant — must hold for new chunkers too).
+
+- [ ] **Step 2**: Run → FAIL.

+`mod_path` for TS is empty (TS modules are file-level, not nested class/namespace at the symbol level — interfaces/types DO live in module scope but their names are unit-level, not parent context). Skip TS `namespace` / `module` declarations: emit them as glue for 1B (the explicit-namespace case is rare in modern TS; documented in 1B Risks).
+
+Module prefix: `mod_prefix = module_path_for_tsjs(&asset.workspace_path.0)`. Join with `.` for symbol.
+
+### Steps
+
+- [ ] **Step 1 (fixtures)**:
+
+```typescript
+// sample.ts
+import { x } from "./other";
+const ANSWER = 42;
+export interface Greet { hello(): string; }
+export type Maybe<T> = T | null;
+export function add(a: number, b: number): number { return a + b; }
+export class Retriever {
+    search(q: string): string[] { return []; }
+    static create(): Retriever { return new Retriever(); }
+}
+export default function () { return 1; }
+```
+
+```tsx
+// sample.tsx
+import React from "react";
+export function Hello({ name }: { name: string }) { return <span>{name}</span>; }
+export const App = () => <Hello name="x" />;  // arrow fn assigned → glue in 1B
+```
+
+- [ ] **Step 2 (failing tests)**: 2 fixture-based tests asserting per-fixture symbols. Asserted symbols (sample.ts):
+  - `src/sample.add` (if workspace_path is `src/sample.ts`)
+  - `src/sample.Greet`, `src/sample.Maybe`, `src/sample.Retriever`, `src/sample.Retriever.search`, `src/sample.Retriever.create`, `src/sample.default`, `src/sample.<top-level>`.
+- For sample.tsx (workspace_path `src/sample.tsx`): `src/sample.Hello`, `src/sample.<top-level>` (App arrow fn rolled into glue).
+- Also: `extractor_supports_only_media_code_typescript`, `deterministic_across_runs`.
+
+- [ ] **Step 3**: Run → FAIL.
+
+- [ ] **Step 4**: Implement `typescript.rs` mirroring `rust.rs` scaffold. Grammar selection by file extension. AST walk per the table above. Module prefix application same shape as Python (prefix joined with `.`).
+
+- [ ] **Step 5**: Wire into `lib.rs`:
+
+```rust
+pub mod typescript;
+pub use typescript::{PARSER_VERSION as TS_PARSER_VERSION, TypescriptAstExtractor};
+```
+
+- [ ] **Step 6**: Tests pass, clippy clean, commit.
+

+
+## Task I: TS chunker (`code-ts-ast-v1`)
+
+Pattern identical to Task F — duplicate `code_rust_ast_v1.rs` with substitutions (`VERSION_LABEL = "code-ts-ast-v1"`, struct `CodeTsAstV1Chunker`, error message). Test module copies the Rust chunker tests with name substitutions + adds `policy_hash_matches_md_heading_v1`.
+
+Commit:
+
+```
+feat(p10-1b): code-ts-ast-v1 chunker (1:1 + oversize split)
+```
+
+---
+
+## Task J: Activate TypeScript in app dispatch
+
+Mirror Task G. Replace TS `bail!` arm with real calls. Add `typescript_file_ingests_and_searches_as_code_citation` integration test using a `src/Foo.ts` fixture.
+
+Commit:
+
+```
+feat(p10-1b): activate TypeScript in ingest_one_code_asset dispatch
+```
+
+---
+
+## Task K: JavaScript Extractor (`javascript.rs`)
+
+Mirror Task H. tree-sitter-javascript single LanguageFn. AST mapping similar to TS but without `interface_declaration` / `type_alias_declaration` / `enum_declaration`. Module prefix via `module_path_for_tsjs`.
+
+Test fixture `sample.js`:
+
+```javascript
+// sample.js
+import { x } from "./other";
+const ANSWER = 42;
+export function add(a, b) { return a + b; }
+export class Retriever {
+    search(q) { return []; }
+    static create() { return new Retriever(); }
+}
+export default function () { return 1; }
+```
+
+Asserted symbols: `src/sample.add`, `src/sample.Retriever`, `src/sample.Retriever.search`, `src/sample.Retriever.create`, `src/sample.default`, `src/sample.<top-level>`.
+
+Wire into `lib.rs`:
+
+```rust
+pub mod javascript;
+pub use javascript::{PARSER_VERSION as JS_PARSER_VERSION, JavascriptAstExtractor};
+```
+
+Commits:
+
+```
+feat(p10-1b): tree-sitter-javascript AST extractor (JavascriptAstExtractor)
+```
+
+---
+
+## Task L: JS chunker (`code-js-ast-v1`) + Activate JS in app dispatch
+
+Combine Task F + Task G shape for JS in a single commit (less ceremony than splitting since the diffs are tiny):
+
+- Chunker: duplicate-with-substitution from `code_rust_ast_v1.rs`. `VERSION_LABEL = "code-js-ast-v1"`, struct `CodeJsAstV1Chunker`.
+- App dispatch: replace JS `bail!` with real calls.
+- Integration test: `javascript_file_ingests_and_searches_as_code_citation`.
+
+Commit:
+
+```
+feat(p10-1b): code-js-ast-v1 chunker + activate JS in app dispatch
+```
+
+---
+
+## Task M: Snapshots + full-suite gate + manual SMOKE
+
+**Files:**
+- Create: `crates/kebab-chunk/tests/code_python_ast_snapshot.rs` + fixture `tests/fixtures/code-sample.py` + baseline `code-sample.chunks.snapshot.json`
+- Create: same for TS (`code_ts_ast_snapshot.rs` + fixture `.ts` + baseline)
+- Create: same for JS (`code_js_ast_snapshot.rs` + fixture `.js` + baseline)
+
+Mirror `crates/kebab-chunk/tests/code_rust_ast_snapshot.rs` exactly for each language. Build the `CanonicalDocument` IN-MEMORY (no `kebab-parse-code` dep crossing the chunk boundary).
+
+- [ ] **Step 1**: Add the 3 snapshot tests. Generate baselines: `UPDATE_SNAPSHOTS=1 cargo test -p kebab-chunk code_{python,ts,js}_ast_snapshot`. Re-run without env var → PASS.
+
+- [ ] **Step 2**: Full-suite gate (memory-conscious):
+  - `cargo clippy --workspace --all-targets -- -D warnings` (one invocation, no parallel).
+  - `cargo test --workspace --no-fail-fast -j 1` (the `-j 1` is mandatory). If the pre-existing `runner_lexical_is_deterministic_per_query_payload` flake reappears (unlikely — was fixed in PR #141 on main and merged before 1B branch was cut), re-run that single test once.
+
+- [ ] **Step 3**: Manual SMOKE (mirror `docs/SMOKE.md` P10-1A-2 flow for each language):
+
+```bash
+cargo build --release
+rm -rf /tmp/kebab-1bsmoke && mkdir -p /tmp/kebab-1bsmoke/ws/{kebab_eval,src}
+echo 'def compute_mrr(): return 1.0' > /tmp/kebab-1bsmoke/ws/kebab_eval/metrics.py
+echo 'export function add(a,b){return a+b;}' > /tmp/kebab-1bsmoke/ws/src/foo.ts
+echo 'export function sub(a,b){return a-b;}' > /tmp/kebab-1bsmoke/ws/src/bar.js
+# (match isolated config block format from docs/SMOKE.md)
+./target/release/kebab --config /tmp/kebab-1bsmoke/config.toml ingest --json | jq '.items[].parser_version' | sort -u
+./target/release/kebab --config /tmp/kebab-1bsmoke/config.toml search "compute_mrr" --code-lang python --json | jq '.hits[0]'
+./target/release/kebab --config /tmp/kebab-1bsmoke/config.toml schema --json | jq '.stats.code_lang_breakdown'
+```
+
+Expected: parser_versions include `code-python-v1`, `code-ts-v1`, `code-js-v1`. Search returns `Citation::Code { lang: "python", symbol: "kebab_eval.metrics.compute_mrr" }`. `code_lang_breakdown` includes all four langs (rust may be 0 unless you also added a .rs).
+
+- [ ] **Step 4**: Commit (snapshot files + any harness tweaks).
+
+```bash
+git add crates/kebab-chunk/tests/
+git commit -m "test(p10-1b): per-language chunker snapshots + full-suite gate"
+```
+
+---
+
+## Task N: Docs + HOTFIXES + version bump
+
+- README: 지원 형식 / 명령 table row adds Python / TypeScript / JavaScript next to Rust. Mermaid stays unchanged (no new external surface crosses the diagram).
+- HANDOFF: P10 row notes 1B merged (3 langs active). Add a one-line entry under 머지 후 결정 cross-linking the HOTFIXES entries.
+- ARCHITECTURE: dependency-graph edge `pcode → core` already present. The new tree-sitter-{python,typescript,javascript} edges to `pcode` add to the description text. Locked-in decisions table: add "1B symbol path: workspace path → module path (Python dotted, TS/JS slash-style); Rust 1A keeps file-scope nesting only — HOTFIXES 2026-05-20".
+- SMOKE: add 1B section mirroring the 1A-2 P10 section structure (config block, ingest / search / schema verification commands) for Python and TS/JS. Compact — one shared section for all three.
+- tasks/INDEX + tasks/p10/INDEX: flip 1B row 🟡→🟢 (on PR open; ✅ on merge).
+- tasks/HOTFIXES.md: TWO dated 2026-05-20 entries:
+  1. **Rust 1A-2 symbol path is file-scope-only; 1B+ uses workspace path → module prefix**. Cross-link to design §3.4. Acceptable inconsistency for now (cost of 1A retrofit = chunker_version bump + reindex for every existing Rust corpus). User-requested retrofit triggers a separate task.
+  2. **Expression-level functions (arrow fn / function expression assigned to const) NOT emitted as separate units in 1B 1차**. They fold into the `<top-level>` glue. Documented limit; future phase may add `lexical_declaration` → inner-expression unwrap.
+  Cross-link both in `tasks/p10/p10-1b-py-ts-js-ast-chunkers.md` Risks/notes.
+- `docs/superpowers/specs/2026-04-27-kebab-final-form-design.md` §10.1: add a one-liner — "p10-1B 활성화 (Python / TypeScript / JavaScript)".
+- `Cargo.toml`: workspace version `0.7.0 → 0.8.0`. `cargo build --release` refreshes Cargo.lock.
+- One commit:
+
+```bash
+git add -A
+git commit -m "docs(p10-1b): README/HANDOFF/ARCHITECTURE/SMOKE/INDEX + HOTFIXES; chore: bump version 0.7.0 → 0.8.0
+
+Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>"
+```
+
+---
+
+## Finalize
+
+- `gitea-pr` open the PR (gitea-ops skill) — title `feat(p10-1B): Python + TS/JS AST chunkers — tree-sitter-{python,typescript,javascript} 코드 색인 활성화`.
+- **Review loop mode** (fixed per workflow memory) until APPROVE → merge → main pull → branch cleanup → `cargo clean` → `gitea-release v0.8.0`.
+
+---
+
+## Self-review checklist (filled by plan author)
+
+- **Spec coverage**: every row of design §1B has a task; §3.4 symbol path covered by Task C + per-language extractors + integration tests; §6.1/§6.2 module structure covered by Tasks E/F/H/I/K/L; §9.1 Tier-1 + oversize fallback inherited from 1A-2 chunker pattern (Tasks F/I/L); §3.5 code_lang already in 1A-2 helper, extended in Task B routing; §5 dispatch covered by Task D; cascade rule (versioning §9) — chunker versions are per-language, fixture snapshots lock behavior.
+- **No placeholders**: all novel logic (module_path helpers, app dispatch generalization, Python AST walk rules) given concretely with full code or exact deltas vs 1A-2. The per-language chunkers are explicit "duplicate code_rust_ast_v1.rs with substitution X/Y/Z" — concrete and verifiable, not vague.
+- **Type consistency**: parser_version constants (`code-{rust,python,ts,js}-v1`) and chunker_version labels (`code-{rust,python,ts,js}-ast-v1`) used consistently across Tasks D/E/F/G/H/I/J/K/L. `module_path_for_python` / `module_path_for_tsjs` referenced consistently as the source of truth for prefixing.

+# kebab — Code Ingest Design
+
+기준일: 2026-05-15
+대상: kebab 워크스페이스를 **코드 corpus** 로 확장 (`Tier 1` AST per-language + `Tier 2` resource-aware + `Tier 3` paragraph fallback). frozen design doc `docs/superpowers/specs/2026-04-27-kebab-final-form-design.md` 의 후속이자, 그 §11 비-스코프 중 "모든 파일 포맷의 완벽한 parsing" 을 **부분적으로** 깨는 첫 spec. 단, multi-workspace / watch mode 같은 다른 비-스코프는 그대로 유지.
+
+대상 사용자 시나리오: 한 부모 디렉토리 (`workspace.root`) 아래 *수십 개의 git repo* 를 clone 한 상태에서, 그 corpus 전체에 의미 검색 + RAG 를 한 곳에서 수행.
+

+
+## 0. 동결된 결정 요약
+
+| # | 결정 | 값 | 근거 |
+|---|------|-----|------|
+| C1 | 스코프 단위 | 한 `workspace.root` 아래 여러 repo (multi-workspace 안 함) | frozen Q10 / §11 그대로 — 부모 디렉토리 한 줄로 커버 |
+| C2 | chunking 전략 | Tier 1 = AST per-language, Tier 2 = resource-aware, Tier 3 = paragraph + line-window | 의미 단위가 언어별로 다름. 일률 적용 불가 |
+| C3 | embedding 모델 | 기존 `multilingual-e5-large` 유지 | 코드 + 문서 동일 벡터 공간 → cross-corpus 검색. embedding_version cascade 회피 |
+| C4 | ignore 통합 | `.gitignore` 자동 honor + `.kebabignore` 추가 layer + 최소 built-in safety net | 사용자 mental model 자연스러움. `.gitignore` 가 source of truth |
+| C5 | repo 인식 | `.git/` walk-up 자동 감지, identifier = dir 이름 | 단순 / deterministic / git remote 미설정 repo 도 안 깨짐 |
+| C6 | branch 처리 | working tree only. branch 변경 후 ingest 는 blake3 hash 차이로 incremental reprocess | git history aware 색인은 §3 도메인 모델 크게 흔듦 — P+ |
+| C7 | Citation variant | 새 `code` variant 도입 (line/page/region/caption/time/**code**) | 의미 분리 명확 — agent / consumer 분기 깔끔 |
+| C8 | search hit 추가 | `SearchHit.repo`, `SearchHit.code_lang` (optional, additive minor) | repo 격리 / 통계 / filter |
+| C9 | 새 filter | `--media code`, `--code-lang <list>`, `--repo <name>` | search ergonomics |
+| C10 | chunker_version | per-language (`code-rust-ast-v1` 등) | 언어별 chunker 독립 진화, §9 cascade rule 깔끔 |
+| C11 | crate 구조 | 새 crate `kebab-parse-code` (모든 언어 mod) + 기존 `kebab-chunk` 모듈 확장 | 22 crates 한 번만 증가. 언어 추가는 모듈 한 쌍 |
+| C12 | symbol path | per-language convention (`mod::fn` / `pkg.cls.method` / `module/Class.method` …) | 각 언어 self-reference 관습 그대로 |
+| C13 | RAG prompt | Phase 1A 는 `rag-v2` 유지. 측정 후 `rag-v3` 도입 검토 | YAGNI |
+| C14 | 특수 파일 | manifest 류 (`Cargo.toml` 등) 는 파일 통째로 1 chunk (`manifest-file-v1`) | 작은 파일은 전체 보기가 더 유용 |
+| C15 | Phase 분할 | 1A Rust → 1B Python+TS/JS → 1C Go+Java/Kotlin → 1D C/C++ → 2 Tier 2 → 3 Tier 3 | 점진 도입, dogfooding 가능 |
+| C16 | built-in skip 최소 | 5 entries: `node_modules/` `target/` `__pycache__/` `.venv/` `venv/` `env/` | `.gitignore` 가 메인 — built-in 은 safety net |
+| C17 | generated header sniff | `@generated` / `DO NOT EDIT` 등 marker 6 종 — 첫 ~500 byte read | 첫 도그푸딩 비용 차단 (protobuf 등) |
+| C18 | size cap | `max_file_bytes = 262144` (256 KiB), `max_file_lines = 5000` default | 대용량 fixture / minified 차단 |

+## 1. 스코프 + 비-스코프
+
+### 1.1 스코프 (이 spec 으로 동결되는 것)
+
+- 코드 / 설정 파일 ingest 파이프라인 (parse → chunk → embed → store → retrieve → answer)
+- 새 Citation variant `code`
+- 새 SearchHit 필드 (`repo`, `code_lang`)
+- 새 search filter (`--media code`, `--code-lang`, `--repo`)
+- 새 chunker_version 라벨 family (`code-{lang}-ast-v1`, `k8s-manifest-resource-v1`, `dockerfile-file-v1`, `manifest-file-v1`, `code-text-paragraph-v1`)
+- 새 crate `kebab-parse-code`
+- 기존 `kebab-chunk` 모듈 확장
+- repo 자동 감지 + `metadata.repo` / `git_branch` / `git_commit`
+- ignore 통합 정책 (`.gitignore` honor + `.kebabignore` + built-in)
+- generated / vendored / size cap skip 정책
+- IngestReport 카운트 분류 확장
+- 새 config 절 `[ingest.code]`
+- Phase 분할 (1A → 1B → 1C → 1D → 2 → 3)
+
+### 1.2 비-스코프 (이 spec 으로 명시적으로 *안 다루는* 것)
+
+- **Multi-workspace** — 여전히 single `workspace.root`. 사용자가 직접 부모 디렉토리 정렬.
+- **Watch mode** — 여전히 명시 ingest 만.
+- **git history aware indexing** — branch / commit 별 snapshot 색인 안 함. working tree 한 시점만.
+- **LSP / go-to-definition / find-references** — 코드 *내비게이션* 은 IDE / CC 가 잘 함. kebab 은 *의미 검색* + *RAG* 만.
+- **Code-specific embedding 모델** — Phase 2+ 측정 후 검토. 현재 spec 에선 e5-large 유지.
+- **`rag-v3` (code-aware prompt)** — Phase 2+ 측정 후 검토.
+- **서브모듈 / git worktree** — `.git/` 가 dir 인 normal repo 만 인식. submodule (`.git` file) 은 metadata.repo 만 null 또는 부모 repo 이름 fallback.
+- **Cross-repo 의도적 dedup** — blake3 content hash 의 우연 dedup 만 존재. 명시적 dedup 로직 안 함.
+- **`kebab://` URL handler** — frozen §11 그대로 P+.
+
+---
+
+## 2. Phase 분할 + 마일스톤
+
+각 phase = 별도 task spec (`tasks/p10/p10-1a-1-code-ingest-framework.md` 등) + 별도 PR. **Phase 1A-1** 이 *프레임워크 일체* (새 crate skeleton, 새 Citation variant, repo metadata, 새 filter, ignore 정책 전체, skip 정책, IngestReport 세분화) 를 들고 들어가는 가장 무거운 phase. 1A-2 이후는 *언어 / chunker 추가* 만.
+
+| Phase | 내용 | 새 crate / 모듈 | 새 chunker_version | 마일스톤 |
+|-------|------|----------------|--------------------|----------|
+| **1A-1** | 프레임워크 일체 — Citation `code` variant, SearchHit `repo`/`code_lang`, 새 filter (`--media code` / `--code-lang` / `--repo`), ignore 통합 정책, skip 정책 (built-in/generated/size), IngestReport 세분화, config `[ingest.code]` 절. `kebab-parse-code` crate **skeleton** (lang/repo/skip 모듈만, 언어 parser 없음) | `kebab-parse-code` 신설 — infrastructure only, language parser 모듈 없음 | *없음* (chunker 추가 0) | wire schema additive minor commit. 기존 markdown corpus 무영향 검증 (regression test). 코드 ingest 아직 활성 안 됨 |
+| **1A-2** | Rust AST chunker 자체 + tree-sitter-rust 도입. Rust 파일 ingest 활성화 | 동일 crate 에 `rust.rs` parser 모듈 + `kebab-chunk/code_rust_ast_v1.rs` | `code-rust-ast-v1` | kebab 자기 자신 dogfooding 가능 |
+| **1B** | Python + TS/JS AST ingest | 동일 crate 에 `python.rs` / `typescript.rs` / `javascript.rs` 모듈 + chunker 추가 | `code-python-ast-v1`, `code-ts-ast-v1`, `code-js-ast-v1` | 사내 ML 코드 + 웹 코드 검색 |
+| **1C** | Go + Java + Kotlin AST ingest | 동일 crate 에 모듈 추가 | `code-go-ast-v1`, `code-java-ast-v1`, `code-kotlin-ast-v1` | 사내 backend 검색 |
+| **1D** | C + C++ AST ingest | 동일 crate 에 모듈 추가 | `code-c-ast-v1`, `code-cpp-ast-v1` | system code 검색 (마지막) |
+| **2** | Tier 2 resource-aware: k8s manifest + Dockerfile + 일반 manifest | 동일 crate 에 모듈 추가 | `k8s-manifest-resource-v1`, `dockerfile-file-v1`, `manifest-file-v1` | k8s 운영 / DevOps 검색 |
+| **3** | Tier 3 fallback: shell + 미지원 확장자 | 동일 crate 에 모듈 추가 | `code-text-paragraph-v1` | 잡 텍스트 fallback |
+
+**Phase 1A 가 1A-1 / 1A-2 로 쪼개진 이유**: 1A 가 들고 들어가는 *프레임워크 surface* (Citation variant, SearchHit 필드, filter 3종, skip 정책, config 절, IngestReport 세분화, 새 crate) 가 *언어 chunker 자체* 와 독립적으로 검증 가능. 1A-1 머지 후 기존 markdown corpus 가 *byte-level identical* 한 출력을 내는지 regression test 로 검증 — 코드 ingest 가 활성화되지 않은 상태에서 wire schema 변경 안전성을 별도 확인. 1A-2 는 Rust chunker 자체에만 집중, dogfooding 가능 지점 = 1A-2 머지.
+
+**Binary version bump 트리거 정리**:
+- **1A-1 머지**: bump 없음. wire 의 additive minor 변경 (CLAUDE.md "wire 의 additive minor 변경 은 backward-compat 이라 본 트리거에 해당 안 됨" 적용). 코드 ingest 미활성 — 사용자 도그푸드 surface 변경 없음.
+- **1A-2 머지**: minor bump (예: `0.6` → `0.7`). 사용자 도그푸딩 가능 = bump 트리거.
+- 이후 phase (1B/1C/1D/2/3) 의 bump 여부는 각 phase 의 task spec 에서 결정 — wire / flag 추가 없으면 patch bump.
+
+---
+
+## 3. 도메인 모델 영향
+
+frozen design `docs/superpowers/specs/2026-04-27-kebab-final-form-design.md` 의 §3 (도메인 모델) 과 §2 (wire schema) 를 *additive minor* 로 확장. breaking 변경 없음. 영향 받는 frozen design 섹션은 [§10 cascade](#10-변경-영향--cascade) 에 정리.
+
+### 3.1 새 Citation variant: `code`
+
+frozen design §2.1 의 5 variant (`line` / `page` / `region` / `caption` / `time`) 에 `code` 추가 → 총 6 variant.
+
+```json
+{
+  "schema_version": "citation.v1",
+  "kind": "code",
+  "path": "kebab/crates/kebab-chunk/src/md_heading_v1.rs",
+  "uri":  "kebab/crates/kebab-chunk/src/md_heading_v1.rs#L142-L168",
+  "line_start": 142,
+  "line_end": 168,
+  "symbol": "MdHeadingV1Chunker::chunk_doc",
+  "lang": "rust"
+}
+```
+
+**Wire 형태 — flat**: 기존 5 variants 와 동일한 패턴 (`Citation::Line` 도 `start` / `end` / `section` 이 top-level, 중첩 없음). serde `#[serde(tag = "kind")]` 외부 tag enum 이라 variant 별 필드가 top-level 에 들어감.
+
+`symbol` 은 nullable — Tier 1 AST chunk 면 채움, Tier 2/3 면 `null`.
+`lang` 은 `--code-lang` filter 와 같은 식별자 (lowercase). null 가능.
+
+기존 5 variant 와 마찬가지로 `path` + `uri` 는 항상 채움. `uri` 는 `path#L<start>-L<end>` (W3C Media Fragments) 그대로.
+
+### 3.2 SearchHit 신규 optional 필드
+
+frozen design §2.2 의 SearchHit 에 두 필드 추가, 모두 optional / nullable, additive minor:
+
+```json
+{
+  "schema_version": "search_hit.v1",
+  "rank": 1,
+  "score": 0.78,
+  "score_kind": "rrf",
+  "chunk_id": "...",
+  "doc_id": "...",
+  "doc_path": "kebab/crates/kebab-chunk/src/md_heading_v1.rs",
+  "heading_path": ["src", "md_heading_v1"],
+  "section_label": "MdHeadingV1Chunker::chunk_doc",
+  "snippet": "...",
+  "citation": { "kind": "code", "...": "citation.v1" },
+
+  "repo": "kebab",          // ← 신규 optional. .git/ walk-up 결과.
+  "code_lang": "rust",      // ← 신규 optional. Tier 1/2/3 모두 채움 (Tier 2 의 yaml 등 포함).
+
+  "retrieval": { "...": "..." },
+  "index_version": "v1.0",
+  "embedding_model": "multilingual-e5-large",
+  "chunker_version": "code-rust-ast-v1"
+}
+```
+
+기존 consumer (Claude Code skill 등) 는 두 필드 미인지 시 무시 — backwards-compat.
+
+Markdown / PDF / 이미지 hit 는 두 필드 모두 null. 코드 hit 도 *repo 외부 single-file ingest* (`kebab ingest-file`) 인 경우 `repo` null 가능.
+
+### 3.3 chunker_version 명명 (per-language)
+
+frozen design §3.2 의 `chunker_version` 라벨 family 확장. **per-language 독립** — 언어 chunker 버그 픽스가 다른 언어 chunks 무효화 안 함.
+
+```text
+기존:
+  md-heading-v1
+  pdf-page-v1
+
+Phase 1A 추가:
+  code-rust-ast-v1
+
+Phase 1B 추가:
+  code-python-ast-v1
+  code-ts-ast-v1
+  code-js-ast-v1
+
+Phase 1C 추가:
+  code-go-ast-v1
+  code-java-ast-v1
+  code-kotlin-ast-v1
+
+Phase 1D 추가:
+  code-c-ast-v1
+  code-cpp-ast-v1
+
+Phase 2 추가:
+  k8s-manifest-resource-v1
+  dockerfile-file-v1
+  manifest-file-v1
+
+Phase 3 추가:
+  code-text-paragraph-v1
+```
+
+cascade rule (frozen design §9):
+- 한 언어 chunker 버그 픽스 → 해당 `code-{lang}-ast-vN` 만 bump → `embedding_records` 의 해당 chunk 만 invalidate → 다음 ingest 에서 해당 언어 파일만 reprocess.
+- 공통 코드 (예: tree-sitter wrapper) 변경 → 영향 받는 모든 언어 chunker 동시 bump.
+
+### 3.4 symbol path 포맷 (per-language convention)
+
+`Citation.code.symbol` 의 값. 각 언어의 *self-reference 관습* 그대로.
+
+| 언어 | 포맷 | 예시 |
+|------|------|------|
+| Rust | `mod::sub::fn_name`, `impl Type::method`, `Trait::method` | `chunk::md_heading_v1::MdHeadingV1Chunker::chunk_doc` |
+| Python | `pkg.module.Class.method`, `pkg.module.func` | `kebab_eval.metrics.compute_mrr` |
+| TS/JS | `module/Class.method`, `module/func`, `module/default` | `src/search/retriever/Retriever.search` |
+| Go | `package.Func`, `package.(Receiver).Method` | `chunk.(*MdHeadingV1Chunker).ChunkDoc` |
+| Java/Kotlin | `package.Class.method` | `com.kebab.chunk.MdHeadingV1Chunker.chunkDoc` |
+| C | `func_name` | `parse_blocks` |
+| C++ | `namespace::Class::method`, `namespace::func` | `kebab::chunk::MdHeadingV1Chunker::chunk_doc` |
+
+**top-level scope** (top-level fn / struct / class 정의 외부의 code, 예: Rust `use` / Python `import` block) 는 `<top-level>` 로 표기. null 아님 — chunk 가 의미 단위 *없는* 영역임을 명시.
+
+**module / namespace 만 있고 symbol 없는 경우** (예: Rust mod 선언만 모인 `lib.rs`): `<module>` 로 표기.
+
+### 3.5 metadata 확장
+
+frozen design §3.6 (Metadata / Provenance) 에 코드 ingest 시 채워지는 필드:
+
+```rust
+pub struct Metadata {
+    // 기존 필드 ...
+    pub lang: Option<String>,         // BCP-47 (자연어). 코드 파일은 보통 null. 코드 안의 주석 dominant lang detection 안 함.
+    pub tags: Vec<String>,
+    // ...
+
+    // 신규 (코드 ingest)
+    pub repo: Option<String>,         // .git/ walk-up 결과. dir 이름.
+    pub git_branch: Option<String>,   // ingest 시점 HEAD branch.
+    pub git_commit: Option<String>,   // ingest 시점 HEAD commit SHA (full 40 hex).
+    pub code_lang: Option<String>,    // tree-sitter parser 이름과 매칭. lowercase.
+}
+```
+
+`code_lang` 식별자 정규화 (이 spec 의 canonical 정의):
+- Rust 파일 (`.rs`) → `rust`
+- Python (`.py`, `.pyi`) → `python`
+- TypeScript (`.ts`, `.tsx`) → `typescript`
+- JavaScript (`.js`, `.jsx`, `.mjs`, `.cjs`) → `javascript`
+- Go (`.go`) → `go`
+- Java (`.java`) → `java`
+- Kotlin (`.kt`, `.kts`) → `kotlin`
+- C (`.c`, `.h`) → `c`
+- C++ (`.cpp`, `.cc`, `.cxx`, `.hpp`, `.hh`, `.hxx`) → `cpp`
+- YAML / k8s manifest (`.yaml`, `.yml`) → `yaml`
+- Dockerfile (`Dockerfile`, `*.dockerfile`) → `dockerfile`
+- TOML (`.toml`) → `toml`
+- JSON (`.json`) → `json`
+- Shell (`.sh`, `.bash`, `.zsh`) → `shell`
+- Make (`Makefile`, `*.mk`) → `make`
+- 미지원 / Tier 3 fallback → null
+
+확장자 sniff 는 `kebab-parse-code` 의 단일 함수 `code_lang_for_path(path: &Path) -> Option<&'static str>` 에서 결정. 이 함수가 *유일한 source of truth*.
+
+---
+
+## 4. Wire schema v1 변경 (모두 additive minor)
+
+### 4.1 변경 요약 표
+
+| schema | 변경 | 영향 |
+|--------|------|------|
+| `citation.v1` | `kind = "code"` variant 추가 + `code: { line_start, line_end, symbol, lang }` 키 추가 | additive minor (기존 consumer 미인지 시 빠짐) |
+| `search_hit.v1` | `repo`, `code_lang` 두 optional 필드 추가 | additive minor |
+| `ingest_report.v1` | `skipped_generated`, `skipped_size_exceeded`, `skipped_builtin_blacklist`, `skipped_gitignore` 카운트 + `skip_examples` 추가 | additive minor |
+| `schema.v1` | `media_breakdown` 에 `code` 카테고리 추가, 새 `code_lang_breakdown` 표 추가 | additive minor |
+| `doctor.v1` | (변경 없음) | — |
+| `answer.v1` | (Phase 1A 변경 없음. citation 객체가 code variant 일 수 있다는 점만 implicit) | — |
+| `fetch_result.v1` | (변경 없음, kind=chunk / doc / span 그대로) | — |
+
+### 4.2 JSON Schema 파일 수정 위치
+
+```
+docs/wire-schema/v1/
+  citation.schema.json          ← code variant 추가
+  search_hit.schema.json        ← repo / code_lang 추가
+  ingest_report.schema.json     ← skip 카운트 + skip_examples 추가
+  schema.schema.json            ← code_lang_breakdown 추가
+```
+
+각 schema 파일에 `"additionalProperties": false` 가 켜져 있으면 새 필드 정의 추가만으로 valid 가 안 됨 — 새 필드를 `properties` 에 명시하고 `required` 는 그대로 유지 (optional).
+
+### 4.3 `--json` 출력 호환성 검증
+
+Phase 1A 구현 시 기존 markdown corpus 의 hit / answer 가 *예전과 byte-level identical* 한 출력 내는지 단위 테스트 추가:
+
+- `search_hit.v1` 의 `repo` / `code_lang` 필드는 markdown hit 에서 *output 에 등장하지 않음* (snake-case omit-null serialization).
+- `ingest_report.v1` 의 새 카운트 필드는 코드 ingest 가 실행되지 않으면 `0` 으로 채워짐 (또는 omit-zero — task spec 단계에서 결정).
+- `citation.v1` 의 `code` 키는 `kind != "code"` variant 에서 항상 absent.
+
+---
+
+## 5. Ingest 파이프라인 변경
+
+### 5.1 Repo 자동 감지
+
+```text
+fn detect_repo(path: &Path) -> Option<RepoMeta> {
+    // path 의 부모 디렉토리에서 위로 .git/ (dir) 만날 때까지 walk.
+    // workspace.root 위로는 안 올라감 (boundary).
+    // .git/ 가 file 인 경우 (worktree marker / submodule) → metadata.repo = None,
+    //   metadata.git_branch / commit = None.
+    // .git/ 가 dir 이면:
+    //   - repo_name = .git/ 의 부모 dir 이름
+    //   - branch = git symbolic-ref HEAD (없으면 detached HEAD → "detached")
+    //   - commit = git rev-parse HEAD (40 hex 또는 None if empty repo)
+}
+```
+
+`git` binary 호출 vs `gix` (gitoxide) library 사용 — task spec 에서 결정. 단 `git` binary 호출은 PATH 의존성 도입 (kebab 의 다른 곳엔 없음) → `gix` 선호.
+
+repo 감지는 ingest 시 *파일당 한 번* 만 — repo 별 캐시 (in-memory HashMap) 로 같은 repo 의 두 번째 파일부터는 lookup hit.
+
+### 5.2 ignore 통합 (`.gitignore` + `.kebabignore` + built-in)
+
+**우선순위** (앞이 강함):
+1. **Built-in safety net** — 항상 적용, 사용자 negate 가능 (`.kebabignore` 의 `!pattern`)
+2. **`.gitignore`** — repo 의 `.gitignore` 자동 honor. nested `.gitignore` 도 적용 (디렉토리 단위 cascade).
+3. **`.kebabignore`** — kebab 만의 추가 layer. workspace.root + 각 디렉토리 별 가능 (현재 동작 그대로).
+
+**Built-in safety net (5 entries 만)**:
+```text
+**/node_modules/
+**/target/
+**/__pycache__/
+**/.venv/
+**/venv/
+**/env/
+```
+
+`env/` 가 모호하지만 (사용자 자식 디렉토리가 우연히 "env" 일 수 있음) Python virtualenv 관습 강해서 포함. 사용자 override 는 `.kebabignore` 의 `!env/` 로.
+
+**구현**:
+- 기존 `kebab-source-fs` 의 `.kebabignore` 처리 코드를 확장.
+- `ignore` crate (gitignore syntax) 그대로 사용. `.gitignore` + `.kebabignore` 를 같은 `Override` 빌더에 add — `ignore` crate 가 둘 다 표준으로 처리.
+- built-in 은 hardcoded `WalkBuilder.add_custom_ignore_filename` 또는 코드 내 `OverrideBuilder` 로.
+
+### 5.3 Generated / vendored skip 정책
+
+**Generated header sniff** — `kebab-source-fs` 의 file scan 단계에서 *blake3 hash 계산 전* 에 실행 (incremental ingest 의 빠른 path 유지):
+
+```text
+fn is_generated_file(path: &Path) -> io::Result<bool> {
+    let mut buf = [0u8; 512];
+    let n = File::open(path)?.read(&mut buf)?;
+    let head = std::str::from_utf8(&buf[..n]).unwrap_or("");
+
+    // 줄 단위 markers — case-insensitive 매칭 (다양한 ecosystem 관습 수용).
+    head.lines().take(10).any(|line| {
+        let l = line.to_ascii_lowercase();
+        l.contains("@generated") ||
+        l.contains("code generated by") ||
+        l.contains("do not edit") ||
+        l.contains("do not modify") ||
+        l.contains("automatically generated") ||
+        l.contains("auto-generated") ||
+        l.contains("autogenerated")
+    })
+}
+```
+
+비용: 파일당 1 read syscall (≤512 byte). 이미 `.gitignore` / built-in 으로 빠진 파일은 이 단계 도달 안 함.
+
+**Skip 시 IngestReport 에 sample 등록** — 디버깅 용 (사용자 "왜 X 파일이 색인 안 됐지?" 시 즉시 답):
+```json
+{
+  "skip_examples": {
+    "generated": [
+      "kebab/crates/proto/src/api.pb.rs",
+      "..."
+    ],
+    "size_exceeded": [
+      "vendor/data/large-fixture.json"
+    ],
+    "builtin_blacklist": ["..."],
+    "gitignore": ["..."]
+  }
+}
+```
+각 카테고리당 처음 5건만. CLI text 모드에서는 카운트만 표시, `--json` 이면 위 schema 그대로.
+
+### 5.4 Size cap
+
+```text
+[ingest.code]
+max_file_bytes = 262144         # 256 KiB
+max_file_lines = 5000           # 둘 중 먼저 hit
+```
+
+- byte cap 은 `fs::metadata().len()` 한 번 — 매우 빠름.
+- line cap 은 byte cap 통과 후 streaming read 로 5000 line 까지 count, 초과 시 skip.
+- 둘 다 `IngestReport.skipped_size_exceeded` 로 카운트, `skip_examples.size_exceeded` 에 sample.
+
+기본값 근거:
+- 256 KiB → 보통 코드 파일 (Rust fn, Python class) 의 100배 이상. minified JS / 대용량 fixture / generated client 의 일반적 사이즈 (수 MB) 는 차단.
+- 5000 line → 한 파일이 한 사람이 이해할 수 있는 한계 근처. 그 이상은 보통 generated.
+
+사용자 override:
+```toml
+[ingest.code]
+max_file_bytes = 1048576    # 1 MiB 로 풀고 싶을 때
+max_file_lines = 20000
+```
+
+### 5.5 IngestReport 세분화
+
+기존 `skipped_by_extension` 옆에 추가:
+
+```json
+{
+  "schema_version": "ingest_report.v1",
+  "indexed": 1234,
+  "unchanged": 5678,
+  "updated": 12,
+  "deleted": 3,
+  "skipped_by_extension": 45,
+  "skipped_gitignore": 2104,
+  "skipped_kebabignore": 8,
+  "skipped_builtin_blacklist": 567,

+    "builtin_blacklist": ["..."],
+    "gitignore": ["..."]
+  },
+  "warnings": [],
+  "duration_ms": 12345
+}
+```
+
+`skipped_by_extension` 은 *지원 안 되는 확장자* — 코드 ingest 후로는 Tier 3 fallback (`code-text-paragraph-v1`) 이 잡아내는 폭이 넓어져서 비율이 줄 것. Tier 3 도 못 잡는 binary 등이 남음.

+```
+
+**의존성**:
+- 각 phase 별로 `tree-sitter-*` dep 추가. Phase 1A 는 `tree-sitter-rust` + `tree-sitter` (core) 만.
+- `gix` (gitoxide) — Phase 1A 부터.
+- `kebab-core`, `kebab-parse-types` (CanonicalDocument / Block / SourceSpan).
+
+**의존성 제약** (frozen design §8 inheritance):
+- `kebab-parse-code` 는 다른 `kebab-parse-*` 크레이트와 동일한 격리 규칙 — store / embed / llm / rag 직접 import 금지.
+- UI crate (`kebab-cli` / `kebab-tui` / `kebab-mcp`) 는 이 crate 직접 import 금지. `kebab-app` facade 통해서만.
+
+### 6.2 `kebab-chunk` 모듈 확장
+
+```text
+crates/kebab-chunk/src/
+├── lib.rs                          # export 추가 (per phase 누적)

+├── manifest_file_v1.rs             # ...
+└── code_text_paragraph_v1.rs       # Phase 3
+```
+
+각 모듈 = 한 chunker 구현체 + `pub use` 로 lib 에 노출. 기존 패턴 (md_heading_v1 / pdf_page_v1) 그대로.
+
+**Chunker trait 변경 없음** — 기존 `Chunker` trait (frozen §7.2) 가 `CanonicalDocument → Vec<Chunk>` 시그니처라 코드도 같은 trait 로 동작.
+
+### 6.3 의존성 그래프 변경
+
+```text
+기존:
+  kebab-app → kebab-parse-md, kebab-parse-pdf, kebab-parse-image
+            → kebab-chunk
+            → ...
+
+추가 (Phase 1A):
+  kebab-app → kebab-parse-code (신규)
+            → kebab-chunk (모듈 추가)
+```
+
+추가 의존성:
+- `kebab-app → kebab-parse-code`
+- `kebab-parse-code → tree-sitter`, `tree-sitter-rust`, `gix`
+- 빌드 영향: `kebab-parse-code` 추가 → workspace `cargo test -p` 단위 한 개 추가. `-j 1` 정책 (frozen CLAUDE.md) 그대로 적용.
+
+### 6.4 `target/` 디스크 영향
+
+frozen CLAUDE.md 에 "target/ 가 90 GB+ 까지 balloon" 경고 있음. 이 spec 으로 22 → 새 모듈들 추가 시 *integration test* 마다 새 binary linkage 추가 → 더 부풀어. **각 phase 머지 후 `cargo clean` 강제 권장** — CLAUDE.md 의 기존 rule 그대로 적용, phase 끝마다 명시.
+
+---
+
+## 7. Search / RAG 표면
+
+### 7.1 새 search filter
+
+`kebab search` 의 기존 filter (`--tag` / `--lang` / `--path-glob` / `--media` / `--ingested-after` / `--trust-min` / `--doc-id`) 에 세 종 추가:
+
+```text
+--media code                       # umbrella — 모든 code Tier 의 chunk
+--code-lang <list>                 # 반복 / comma — rust,python 식. OR 매칭.
+--repo <name>                      # 반복 가능. OR 매칭.
+```
+
+기존 정책 일관:
+- 반복 가능 flag 는 OR 매칭 (`--repo kebab --repo other`).
+- `--code-lang rs` 같은 alias 는 미지원 — *full identifier* (`rust`) 만. 일관성 위해.
+- 모르는 `--code-lang` 값 → empty hits (`--media` 와 동일 정책).
+- filter flags 간은 AND (`--media code --code-lang rust` → 코드이면서 Rust).
+
+### 7.2 `kebab schema` stats 확장
+
+frozen design §2.5 / p9-fb-37 의 `stats.media_breakdown` 에 `code` 카테고리 추가:
+
+```json
+{
+  "schema_version": "schema.v1",
+  "stats": {
+    "media_breakdown": {
+      "markdown": 1234,
+      "pdf": 56,
+      "image": 78,
+      "audio": 0,
+      "code": 4567,       // ← 신규
+      "other": 12
+    },
+    "lang_breakdown": {       // 기존 — 자연어
+      "ko": 1100,
+      "en": 234,
+      "null": 134
+    },
+    "code_lang_breakdown": {  // ← 신규 — 프로그래밍 언어 (chunk 수)
+      "rust": 2345,
+      "python": 1234,
+      "typescript": 567,
+      "yaml": 89,
+      "go": 332
+    },
+    "repo_breakdown": {       // ← 신규 — repo 별 chunk 수
+      "kebab": 1234,
+      "internal-api": 567,
+      "...": "..."
+    },
+    "index_bytes": 1234567890,
+    "stale_doc_count": 12
+  }
+}
+```
+
+`repo_breakdown` 도 추가하기로 — 사용자가 "어느 repo 가 가장 많이 색인 됐지?" 확인 가능.
+
+### 7.3 RAG prompt (Phase 1A 는 `rag-v2` 그대로)
+
+Phase 1A 에서는 코드 chunk 가 *일반 도큐먼트* 로 prompt 에 들어감:
+
+```text
+[#1] (code: kebab::chunk::md_heading_v1::MdHeadingV1Chunker::chunk_doc)
+fn chunk_doc(&self, doc: &CanonicalDocument) -> Result<Vec<Chunk>> {
+    ...
+}
+
+[#2] (code: kebab::chunk::pdf_page_v1::PdfPageV1Chunker::chunk_doc)
+...
+```
+
+prompt 의 source identifier 가 *file path + symbol* 둘 다 들어가게 — symbol 이 있으면 *symbol* 을 우선 표시, 없으면 file path.
+
+`rag-v2` 의 기존 규칙 ("fact 인용 시 [#번호] 앞에 chunk 속 원문 큰따옴표") 은 코드에서 좀 어색할 수 있음 (코드의 큰따옴표는 string literal). 측정 후 어색하면 Phase 2+ 에서 `rag-v3` (code-aware) 도입.
+
+### 7.4 `kebab inspect` / `kebab fetch` 영향
+
+기존 `kebab inspect chunk <id>` 출력에서 `Citation::Code` variant 의 `symbol` / `code_lang` 표시. text 모드 출력 변경:
+
+```text
+chunk_id:        abc123...
+doc_path:        kebab/crates/kebab-chunk/src/md_heading_v1.rs
+line range:      L142-L168
+symbol:          MdHeadingV1Chunker::chunk_doc          ← 신규 (code variant 에서만)
+code_lang:       rust                                   ← 신규
+repo:            kebab                                  ← 신규
+chunker_version: code-rust-ast-v1
+```
+
+`kebab fetch chunk` / `kebab fetch span` 은 변경 없음 — 본문 byte 그대로 반환.
+
+---
+
+## 8. Config 변경
+
+### 8.1 신규 `[ingest.code]` 절
+
+```toml
+[ingest.code]
+# Generated header sniff 활성화. 첫 ~500 byte 의 6 markers 중 하나 발견 시 skip.
+skip_generated_header = true
+
+# 파일당 max byte (bytes). 초과 시 skip.
+max_file_bytes = 262144     # 256 KiB
+
+# 파일당 max line. 초과 시 skip. byte cap 통과 후 검사.
+max_file_lines = 5000
+
+# 사용자 추가 skip 패턴. gitignore 문법. built-in / .gitignore / .kebabignore 외 추가.
+extra_skip_globs = []
+
+# AST chunk 가 너무 길 때 fallback line-window 적용 임계.
+# 단일 fn / class 가 이 라인 수 넘으면 paragraph fallback 적용.
+ast_chunk_max_lines = 200    # 단일 chunk 최대 라인
+
+# Tier 3 fallback (paragraph + line-window) 시 line-window 사이즈.
+fallback_lines_per_chunk = 80
+fallback_lines_overlap = 20
+```
+
+기본값 근거:
+- `skip_generated_header = true` — 안전 default. 미스 케이스 (사용자가 generated 도 색인 원함) 는 명시적 false.
+- `max_file_bytes = 262144` — minified JS / 대용량 generated 차단 충분.
+- `max_file_lines = 5000` — 한 사람이 한 번에 이해할 수 있는 코드 한계 근처.
+- `ast_chunk_max_lines = 200` — 사람 인지 한계 + retrieval token budget.
+- `fallback_lines_per_chunk = 80`, `overlap = 20` — RAG 컨벤션의 보수적 default.
+
+### 8.2 기본값 + override 정책
+
+- 모든 키 optional. 누락 시 위 default.
+- `KEBAB_*` env override 안 지원 (이건 dev / debug 가 아닌 정책 설정).
+- `--config <path>` 로 격리 테스트 가능 (XDG 의존 안 함).
+
+### 8.3 `config.toml` 의 기존 `[workspace]` 절 영향
+
+변경 없음. `workspace.root`, `exclude` 그대로. `.gitignore` / `.kebabignore` honor 정책은 *기본 동작* 으로 config 키 없이 active — 사용자가 끄고 싶으면 `.kebabignore` 의 `!pattern` 으로 override.
+
+---
+
+## 9. Tier 별 chunker 상세
+
+### 9.1 Tier 1 — AST per-language
+
+**입력**: `CanonicalDocument` with `Block::Code { lang: Some("rust"), code: "..." }`.
+**출력**: `Vec<Chunk>` — 각 chunk 가 AST 의 *top-level 의미 단위* 또는 fallback unit.
+
+**Rust 예시 (Phase 1A)**:
+
+tree-sitter 의미 단위:
+- `function_item` → 1 chunk
+- `impl_item` 의 각 `function_item` → 1 chunk per method
+- `struct_item` / `enum_item` / `trait_item` → 1 chunk (선언 + doc comment)
+- `mod_item` 의 *내용물* → 재귀 분해
+- top-level `use` / `extern crate` / `const` / `static` block → 한 chunk 로 모음 (`<top-level>` symbol)
+
+**ast_chunk_max_lines 초과 시 fallback**:
+- 단일 fn 이 200 line 넘으면 paragraph (blank-line) 기반으로 split.
+- 각 sub-chunk 의 symbol 은 `function_name [part 1/N]` 식으로 표기.
+- 이 동작은 `kebab-chunk/src/code_rust_ast_v1.rs` 내부에서.
+
+**citation 의 line range**: tree-sitter node 의 `start_position.row` / `end_position.row` (0-indexed → +1 로 1-based).
+
+**예시 input → output**:
+```rust
+// src/lib.rs
+pub fn parse(input: &str) -> Result<Doc> {
+    // 50 lines
+}
+
+impl Chunker for Foo {
+    fn chunk_doc(&self, doc: &Doc) -> Vec<Chunk> {
+        // 80 lines
+    }
+
+    fn name(&self) -> &str { "foo-v1" }
+}
+```
+
+→ chunks:
+1. `parse`, lines 1-50, symbol = `parse`
+2. `Foo::chunk_doc`, lines 53-132, symbol = `Foo::chunk_doc` (impl 의 method)
+3. `Foo::name`, lines 134-134, symbol = `Foo::name`
+
+### 9.2 Tier 2 — resource-aware
+
+**k8s-manifest-resource-v1**:
+- YAML multi-document split (`---` separator).
+- 각 document 마다 1 chunk.
+- chunk metadata: `kind: Deployment`, `apiVersion`, `metadata.name`, `metadata.namespace`.
+- citation 의 `symbol` 필드: `<kind>/<namespace>/<name>` (e.g., `Deployment/prod/api-server`). namespace 없으면 `<kind>/<name>`.
+- yaml 파싱 실패 (invalid YAML, 또는 k8s schema 가 아닌 일반 yaml) 시: `code-text-paragraph-v1` 로 fallback 처리.
+
+**dockerfile-file-v1**:
+- Dockerfile 전체 = 1 chunk.
+- symbol = `<dockerfile>`.
+- citation 의 line range = 1 ~ EOF.
+- ARG / FROM / RUN / COPY / CMD 등은 chunk 내부 plain text 로 보존.
+
+**manifest-file-v1** (Cargo.toml, package.json, pyproject.toml, go.mod, pom.xml, build.gradle, tsconfig.json 등):
+- 파일 통째로 1 chunk.
+- symbol = `<manifest>`.
+- citation 의 line range = 1 ~ EOF.
+
+### 9.3 Tier 3 — paragraph + line-window fallback
+
+**code-text-paragraph-v1** — shell script, 미지원 확장자, AST 실패 시 fallback:
+- 빈 줄 (blank line) 기준으로 paragraph 분할.
+- paragraph 가 `fallback_lines_per_chunk` (default 80) 넘으면 line-window split with `fallback_lines_overlap` (default 20).
+- symbol 은 null. citation 은 `Citation::Code { symbol: None, lang: Some("shell") }` 또는 lang 미지정.
+

+
+## 10. 변경 영향 / cascade
+
+### 10.1 Frozen design doc 갱신 (이 spec 머지와 동시)
+
+`docs/superpowers/specs/2026-04-27-kebab-final-form-design.md` 의 다음 섹션 갱신:
+
+| 섹션 | 갱신 내용 |
+|------|-----------|
+| §0 동결된 결정 요약 | "코드 ingest 추가" 1줄. cross-link to 2026-05-15 spec |
+| §2.1 Citation | 5 → 6 variants, `code` 추가 |
+| §2.2 SearchHit | `repo`, `code_lang` optional 필드 |
+| §2.4 IngestReport | skip 카운트 4종 + skip_examples |
+| §2 schema.v1 (fb-37 추가분) | `code` media + `code_lang_breakdown` + `repo_breakdown` |
+| §3.2 Versions / labels | chunker_version family 확장 (per-language pattern) |
+| §3.6 Metadata | `repo`, `git_branch`, `git_commit`, `code_lang` 필드 |
+| §8 모듈 경계 | `kebab-parse-code` 추가 + 의존성 규칙 inheritance |
+| §11 동결 범위 | "code ingest" 가 더 이상 비-스코프 아님 명시. 단 multi-workspace / watch / history aware 는 그대로 비-스코프 |
+
+### 10.2 cascade rule (frozen §9) 영향
+
+- `parser_version` cascade: 각 phase 의 새 parser version (`code-rust-parse-v1` 등) 추가. 기존 markdown / pdf 무영향.
+- `chunker_version` cascade: per-language 라벨 → 한 언어 chunker 변경이 다른 언어 chunks 무효화 안 함.
+- `embedding_version` cascade: 변경 없음 (`multilingual-e5-large` 그대로).
+- `prompt_template_version` cascade: Phase 1A 는 `rag-v2` 그대로 → 무영향.
+- `index_version` cascade: SQLite DDL 변경 없으면 무영향. metadata.repo / git_branch / git_commit 필드는 *Metadata* 의 JSON blob 안에 추가 — DDL 변경 안 필요 (frozen §5 의 `documents.metadata_json TEXT` 가 free-form).
+
+### 10.3 V00X migration?
+
+SQLite DDL 변경 없음 → V00X migration 불요. `documents.metadata_json` 의 free-form 내부에 새 키 (`repo`, `git_branch`, `git_commit`, `code_lang`) 가 들어감. 기존 markdown / pdf chunk 들의 metadata_json 은 그대로.
+
+### 10.4 Binary version bump
+
+[§2 Phase 분할 표 하단 "Binary version bump 트리거 정리"](#2-phase-분할--마일스톤) 참조. 요지:
+- **1A-1 머지** → bump 없음 (wire additive minor + 사용자 surface 변경 없음).
+- **1A-2 머지** → minor bump (`0.6` → `0.7`, 사용자 도그푸딩 시작).
+- 이후 phase 는 각 task spec 에서 결정 (wire / flag 추가 없으면 patch bump).
+
+---
+
+## 11. Open questions (Phase 1A task spec 단계에서 픽스)
+
+이 spec 은 *프레임워크* 까지만 동결. 다음 항목은 Phase 1A 의 task spec 작성 시 결정:
+
+1. **AST chunk 의 minimum size** — 5-line fn 도 한 chunk? 또는 minimum threshold (예: ≥ 10 line) 미만은 인접 fn 과 merge? *영향*: chunk 수 폭증 vs retrieval miss.
+
+2. **doc_id 충돌 위험** — `Cargo.toml` 두 repo 의 content 가 우연히 동일 → blake3 hash 동일 → 같은 doc? frozen §4.2 의 ID recipe 확인 필요. *영향*: 한 doc 이 두 repo 에서 출처 표시. 해결: doc_id recipe 에 repo / path 포함 여부 확인.
+
+3. **`--code-lang` 식별자 정규화 (canonical)** — `rust` / `python` / `typescript` 의 풀네임만 vs `rs` / `py` / `ts` 짧은 alias 도 허용? 이 spec 은 풀네임만 — task spec 에서 alias 매핑 명시.
+
+4. **TUI surface 변경 시점** — Phase 1A 에 포함 vs 별도 Phase 4 (TUI code rendering)? *영향*: TUI 의 Library/Inspect 패널에서 code citation 의 symbol/lang/repo 렌더. 일단 Phase 1A 에 *최소 변경* (citation 표시) 만 포함, 별도 인터랙션 (예: `g` 키로 LSP 식 navigation) 은 P+.
+
+5. **AST chunk symbol path 의 *depth 한계*** — Rust 의 nested impl / nested mod 가 깊으면 `outer::inner::deepest::method` 식 path 가 길어짐. 60 char cap + 중간 생략 (`outer::…::method`)? Phase 1A 의 task spec 에서 cap 정책 결정.
+
+6. **`gix` 의 binary size 영향** — `kebab-parse-code` → `gix` dep 도입이 release binary 크기에 얼마나 영향? `git2` (libgit2) 는 C dep 이라 안 쓰기로 — `gix` 가 pure rust. binary size 영향 측정 후 결정.
+
+7. **k8s manifest 의 `kind` 인식 범위** — `Deployment` / `Service` / `ConfigMap` 등 표준 외 *CRD* (custom resource) 처리? Phase 2 의 task spec 에서 결정. 일단 *모든 yaml document 의 `kind` 필드 그대로* 사용 (CRD 포함 자동 처리).
+
+---
+
+## 12. 다음 단계
+
+1. **이 spec 의 사용자 검토** — 빠진 결정 / 모순 / 추가 우려 확인.
+2. 검토 통과 시 `tasks/p10/` 디렉토리 신설 + `tasks/p10/INDEX.md` 추가 + `tasks/INDEX.md` 에 phase 10 entry.
+3. **Phase 1A-1 task spec 작성** (먼저) — `tasks/p10/p10-1a-1-code-ingest-framework.md`. `contract_sections` 로 `[§2.1, §2.2, §2.4, §2 schema.v1, §3.6, §8, §11]` (chunker 추가 없음 — §3.2 chunker_version 갱신은 1A-2 와 함께).
+4. **Phase 1A-2 task spec 작성** (1A-1 머지 후) — `tasks/p10/p10-1a-2-rust-ast-chunker.md`. `contract_sections` 로 `[§2.1 (code variant 실 사용), §3.2 (code-rust-ast-v1 추가), §3.4 (Rust symbol path)]`.
+5. Frozen design doc (2026-04-27) 갱신을 *Phase 1A-1 PR* 에 동봉 (이 spec 의 §10.1 표 그대로, 단 §3.2 chunker_version 부분은 1A-2 에서).
+6. writing-plans skill 로 Phase 1A-1 의 구현 계획 (작업 단위) 작성.
+7. Phase 1A-1 머지 후 regression test 통과 확인 → Phase 1A-2 구현 계획 작성 → 머지 → kebab 자기 자신 dogfooding → 측정 → 다음 phase 진행 결정.
+
+---
+
+## 부록 A — 의사 결정 회의록 (이 spec 작성 시 사용자와의 brainstorming 요약)
+
+이 spec 작성에 들어간 결정들의 *왜* 를 짧게 (감사용 / 미래 재고 시 참조):
+
+- **시나리오**: "한 부모 dir 아래 수십 개 repo + 의미 검색 + RAG" — kebab 의 cross-corpus 가치를 코드까지 확장.
+- **chunking 전략**: 사용자가 길 B (AST per-language) 명시 선택. 작성자 추천은 길 C (A 로 시작 측정 후 승급) 였으나 사용자 결정 존중.
+- **언어 범위**: 사용자 초기 답 (Rust/Python/TS-JS/Go-Java-Kotlin/C/C++/Shell/Dockerfile/yaml) 을 Tier 1/2/3 으로 재분류 → AST 가 의미 있는 곳에만 AST 적용. 작성자 push back 결과.
+- **embedding 모델**: e5-large 유지. cross-corpus 가치 + cascade 비용 회피.
+- **Citation variant**: 사용자가 `(a)-2` (새 `code` variant) 선택. 작성자 추천은 `(a)-1` (line variant 재사용) 였으나 의미 분리 명확함이 결정 요인.
+- **built-in blacklist**: 사용자가 *축소* 요청 → 5 entry 최종. `.gitignore` 가 source of truth, built-in 은 safety net 만.
+- **Phase 분할**: 사용자가 "되도록 많은 디테일 spec → Phase 1A 부터 구현" 명시. 이 spec 이 그 프레임워크 동결, phase 별 구현은 별도 task spec.
