## 3. Extractor Audit Script

### 3.1 Create Audit Script
- [x] **3.1.1** Create `scripts/audit_node_extractors.py` (mirror `scripts/audit_extractors.py`)

- [x] **3.1.4** Print extracted data structure with field names
- [x] **3.1.5** Add VALUE SAMPLES for discriminator fields (in KITCHEN_SINK_CODE)

### 3.2 Generate Ground Truth
- [x] **3.2.1** Run `python scripts/audit_node_extractors.py > node_extractor_truth.txt`
- [x] **3.2.2** Review output for accuracy (shows all 37 Node tables with column specs)
- [x] **3.2.3** Generated `node_extractor_truth.txt` in repo root

## 4. Two-Discriminator Pattern (If Applicable)

**STATUS: SKIPPED (Not Applicable)**

**Analysis:** The two-discriminator pattern (`*_kind` + `*_type`) is required when consolidating disparate semantic concepts into a single table (like Python's `python_loops` with `loop_kind`). Node.js schema uses **Framework-Segregated Tables** (`react_components`, `vue_components`, `angular_modules`) - we did NOT merge these into a generic `javascript_components` table. The existing `type` columns in `react_components` (function/class) and `vue_components` (options/composition) are sufficient.

### 4.1 Analyze Tables
- [x] **4.1.1** Review Python schema for two-discriminator pattern usage - DONE
- [x] **4.1.2** Identify Node tables that consolidate multiple types - NONE FOUND
- [x] **4.1.3** Document which tables need `*_kind` + `*_type` columns - N/A

### 4.2 Apply Pattern (if tables identified)
- [N/A] **4.2.1** Add discriminator columns to identified tables - SKIPPED
- [N/A] **4.2.2** Update storage handlers to populate discriminators - SKIPPED
- [N/A] **4.2.3** Add contract tests for discriminator values - SKIPPED

## 5. Codegen Regeneration

- [x] **5.1** Run `python -m theauditor.indexer.schemas.codegen` (auto-ran during aud full)
- [x] **5.2** Verify `generated_types.py` updated with new tables
- [x] **5.3** Verify `generated_cache.py` updated
- [x] **5.4** Verify `generated_accessors.py` updated
- [x] **5.5** Run `ruff check theauditor/indexer/schemas/generated_*.py`

## 6. Final Validation

- [x] **6.1** Run `aud full --offline` on codebase (all 25 phases passed)
- [x] **6.2** Query junction tables - verify data populated (tables exist, 0 rows expected without Vue/Angular extraction)
- [x] **6.3** Query removed columns don't exist (verified via contract tests)
- [x] **6.4** Run all tests: `pytest tests/test_node_schema_contract.py tests/test_schema_contract.py -v` (40 passed)
- [x] **6.5** Run `ruff check theauditor/` (passed after auto-fix)

## 7. Documentation Update

- [x] **7.1** Update `node_receipts.md` to mark Phases 3-4 as COMPLETE
- [x] **7.2** Update `CLAUDE.md` database table counts (136->144, Node 29->37)
- [x] **7.3** `Architecture.md` - No update needed (schema change is additive, not architectural)
