## Task 4: Node Module Resolution (Post-Indexing, Database-First)

**Estimated Time**: 4-8 hours (reduced - simpler architecture)
**Files Modified**: `theauditor/indexer/extractors/javascript_resolvers.py`

**Architecture**: Post-indexing resolver using database queries (NO filesystem I/O)

### 4.1 Read and Understand Current Architecture

- [x] 4.1.1 Read existing resolvers in `javascript_resolvers.py`
  - **What to understand**: Pattern used by `resolve_handler_file_paths`, `resolve_cross_file_parameters`
  - **Key pattern**: Load data from DB, process, update DB

- [x] 4.1.2 Read `import_styles` table schema
  - **Command**: `aud blueprint --structure` or check database.py
  - **What to understand**: Current columns, what needs to be added

- [x] 4.1.3 Read `files` table structure
  - **What to understand**: How indexed file paths are stored
  - **Key column**: `path` - the resolved file path

### 4.2 Schema Change

- [x] 4.2.1 Add `resolved_path` column to `import_styles` table definition
  - **Location**: `theauditor/indexer/schemas/node_schema.py:438`
  - **Type**: TEXT, nullable (NULL = unresolved)
  - **Note**: No migration - DB regenerated on each `aud full`
  - **DONE**: 2025-11-28

### 4.3 Implement resolve_import_paths() Method

- [x] 4.3.1 Add `resolve_import_paths()` static method to `JavaScriptResolversMixin`
  - **Location**: `javascript_resolvers.py:567-634`
  - **Signature**: `@staticmethod def resolve_import_paths(db_path: str):`
  - **DONE**: 2025-11-28

- [x] 4.3.2 Implement Step 1: Load indexed paths
  - **Query**: `SELECT path FROM files WHERE ext IN ('.ts', '.tsx', '.js', '.jsx', '.vue', '.mjs', '.cjs')`
  - **Store**: `indexed_paths = {row[0] for row in cursor.fetchall()}`

- [x] 4.3.3 Implement Step 2: Load path aliases
  - **Logic**: Detect `src/` directory pattern, set up `@/` and `~/` aliases
  - **Future**: Parse actual tsconfig.json paths field

- [x] 4.3.4 Implement Step 3: Query imports to resolve
  - **Query**: `SELECT rowid, file, package FROM import_styles WHERE package LIKE './%' OR ...`
  - **Filter**: Only relative (`./`, `../`) and aliased (`@/`, `~/`) imports

- [x] 4.3.5 Implement Step 4: Resolution loop
  - **For each import**: Call `_resolve_import()`, update DB if resolved

### 4.4 Implement Helper Functions

- [x] 4.4.1 Implement `_load_path_aliases()` function
  - **Location**: `javascript_resolvers.py:637-666`
  - **Input**: cursor
  - **Output**: `dict[str, str]` mapping aliases to base paths
  - **Logic**: Detect src/ directory, set up common aliases

- [x] 4.4.2 Implement `_resolve_import()` function
  - **Location**: `javascript_resolvers.py:669-725`
  - **Input**: `import_path`, `from_file`, `indexed_paths`, `path_aliases`
  - **Output**: `str | None` (resolved path or None)
  - **Steps**:
    1. Expand path aliases
    2. Resolve relative paths
    3. Try extension/index variants
    4. Check against `indexed_paths` set

- [x] 4.4.3 Implement `_normalize_path()` function
  - **Location**: `javascript_resolvers.py:749-766`
  - **Input**: path string with potential `..` segments
  - **Output**: normalized path
  - **Logic**: Handle `..` by popping parent directories

### 4.5 Integrate with Indexer Pipeline

- [x] 4.5.1 Add `resolve_import_paths()` call to orchestrator
  - **File**: `theauditor/indexer/orchestrator.py:468-471`
  - **DONE**: 2025-11-28
  - **Code added**:
    ```python
    if os.environ.get("THEAUDITOR_DEBUG"):
        print("[INDEXER] PHASE 6.10: Resolving import paths...", file=sys.stderr)
    JavaScriptExtractor.resolve_import_paths(self.db_manager.db_path)
    self.db_manager.commit()
    ```

### 4.6 Testing (COMPLETE)

- [x] 4.6.1 Create unit test for `_resolve_import()`
  - **DONE**: 2025-11-28 via `tests/verify_vue_resolution.py`
  - **Test cases verified**:
    - `./Card` from `Button.vue` -> `src/components/Card.vue` PASS
    - `../utils` from `Button.vue` -> `src/utils.ts` PASS
    - `../api` from `Button.vue` -> `src/api/index.ts` PASS (index resolution)
    - `../../lib/shared` from `Button.vue` -> `lib/shared.js` PASS (parent traversal)

- [x] 4.6.2 Create integration test
  - **DONE**: 2025-11-28 via `tests/verify_vue_resolution.py`
  - **Result**: 6/7 imports resolved (85.7%) - exceeds 80% target
  - **Note**: lodash (bare specifier) correctly skipped

- [x] 4.6.3 Verify no filesystem I/O
  - **DONE**: 2025-11-28 (Architecturally guaranteed - uses indexed_paths set, no os.path calls)
