## 2. The Great Purge (Dead Code Deletion) ✓ COMPLETE

### 2.1 Add `__all__` Declarations

These prevent false-positive F401 (unused import) warnings on intentional re-exports.

- [x] 2.1.1 `theauditor/ast_extractors/__init__.py`: **ALREADY HAS `__all__`** (verified 2025-11-25)
- [x] 2.1.2 `theauditor/indexer/__init__.py`: **ALREADY HAS `__all__`** (verified 2025-11-25)
- [x] 2.1.3 `theauditor/rules/__init__.py`: **ALREADY HAS `__all__`** (verified 2025-11-25)
- [x] 2.1.4 `theauditor/taint/__init__.py`: **ALREADY HAS `__all__`** (verified 2025-11-25)

### 2.2 Delete ZERO FALLBACK Violations

**CRITICAL:** For each file, follow this pattern:
1. Open file
2. Delete the exception handlers listed
3. Verify imports work: `python -c "import theauditor.<module>"`
4. Run: `aud full --offline`
5. If crashes, FIX THE ROOT CAUSE (don't restore the fallback)

#### 2.2.1 Clean `theauditor/fce.py`

- [x] 2.2.1.1 **ALREADY CLEAN** (verified 2025-11-26)
  - Verification: `grep -n "except.*json.JSONDecodeError" theauditor/fce.py` returned 0 matches
  - All JSON decode fallbacks removed in prior session

- [x] 2.2.1.2 **ALREADY CLEAN** (verified 2025-11-26)
  - No sqlite3.Error handlers found that violate ZERO FALLBACK policy

- [x] 2.2.1.3 Verification: **PASS** - import successful

#### 2.2.2 Clean `theauditor/context/query.py`

- [x] 2.2.2.1 **ALREADY CLEAN** (verified 2025-11-26)
  - Verification: `grep -n "except sqlite3.OperationalError" theauditor/context/query.py` returned 0 matches

  - Verification: `grep -n "except" theauditor/rules/frameworks/express_analyze.py` returned 0 matches
  - No exception handlers found in file - already compliant with ZERO FALLBACK policy

- [x] 2.2.3.2 Verification: **PASS** - import successful

#### 2.2.4 Clean `theauditor/rules/sql/sql_injection_analyze.py`

- [x] 2.2.4.1 **ALREADY CLEAN** (verified 2025-11-25)
  - Verification: `grep -n "except" theauditor/rules/sql/sql_injection_analyze.py` returned 0 matches
  - No exception handlers found in file - already compliant with ZERO FALLBACK policy

- [x] 2.2.4.2 Verification: **PASS** - import successful

**Approach:** Manual Edit tool, file-by-file with READ verification before each edit.
**Directive:** NO SCRIPTS, NO RUFF --FIX, NO AUTOMATION (Architect directive)

**Final Status (2025-11-26, Session 8):**
- Initial count: 731 F401 errors
- After Session 1: 655 F401 errors (76 fixed)
- After Session 2: 586 F401 errors (69 fixed)
- After Session 3: 274 F401 errors (312 fixed)
- After Session 4: 146 F401 errors (128 fixed)
- After Session 5: 91 F401 errors (55 fixed)
- After Session 6: 40 F401 errors (51 fixed)
- After Session 7: 18 F401 errors (22 fixed)
- **After Session 8: 0 F401 errors (18 fixed) - 100% COMPLETE**

**Directories/Files COMPLETE (0 F401 errors):**
- ast_extractors/ (Session 2)
- commands/ (Session 3)

- universal_detector.py (Session 7)

**Session 4 Commits:**
- `4a88dee` - refactor: remove unused imports from indexer/schemas and indexer/storage

**Critical Fixes Applied:**
- `typescript_impl.py`: Restored `import sys` (used 35+ times)
- `taint/__init__.py`: Fixed TaintPath import (was re-exported from core.py, moved to taint_path.py)
- Session 4: Fixed module-level `import os` in storage/base.py and storage/infrastructure_storage.py (local imports inside methods shadow module-level)
- Session 4: Moved ASTCache import from core.py to __init__.py (was re-exported, not used in core.py)

**Verification Method (Per Directive):**
1. READ file first
2. GREP for actual usage (not docstrings)
3. **GREP for re-exports** - check if other files import from this module
4. Verify imports work: `python -c "import theauditor.<module>"`
5. Run ruff check --select F401 on file

## Rejected Tasks (Lead Auditor Decision)

The following were explicitly rejected as "developer fetish":

| Task | Rule | Verdict | Reason |
|------|------|---------|--------|
| Sort imports | I001 | **REJECTED** | Zero operational value, causes merge conflicts |
| Extract magic numbers | PLR2004 | **REJECTED** | Unless 3+ uses or security-critical |
| Type internal helpers | N/A | **REJECTED** | If AI can't understand 5 lines, function is the problem |
| Docstring formatting | N/A | **REJECTED** | Time sink for no AI benefit |
