---

## Detailed Test Results

### ✅ Test 4.3: Reset Module (Priority 1)

**Command**: `tito module reset 04 --force`

**Initial Result**: ❌ FAILED
- Module reset looked for files in `modules/` instead of `src/`
- Used short filename (`losses.py`) instead of full (`04_losses.py`)

**Bug Found**: Bug #1 - Reset command uses wrong directory path (HIGH severity)

**Fix Applied**:
- Updated `tito/core/config.py` line 50: `modules/` → `src/`
- Updated `module_reset.py` lines 248, 307: short name → full module name

**Final Result**: ✅ PASS
- Backup created successfully (`.tito/backups/04_losses_TIMESTAMP/`)
- Export removed (`tinytorch/core/losses.py` deleted)
- Source restored from git HEAD
- Progress tracking updated (4/21 → 3/21)
- Module status changed from "✅ Done" to "🚀 Working"

**Success Criteria Met**:
- ✅ Creates backup before resetting
- ✅ Removes from completed list
- ✅ Unexports from tinytorch/
- ✅ Restores source files to git HEAD
- ✅ Can start module again fresh

**Side Effect Discovered**: Bug #2 - Reset doesn't update `__init__.py` imports (HIGH severity)

---

### ✅ Test 3.1: Complete Module with Failing Tests (Priority 1)

**Command**: `tito module complete 02` (with intentionally broken test)

**Test Modification**:
```python
# Intentionally changed assertion to fail:
assert np.allclose(result.data, [0.99])  # Should be [0.5]
```

**Result**: ✅ PASS - Test failure handled correctly

**Output**:
```
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 Step 1/3: Running Tests

Errors:
AssertionError: sigmoid(0) should be 0.5, got [0.5]

   ❌ Tests failed for 02_activations
   💡 Fix the issues and try again
```

**Verification**:
- Module 02 remained "✅ Done" (not re-marked)
- Export did NOT happen
- Progress tracking did NOT update
- Exit code: 1 (error)

**Success Criteria Met**:
- ✅ Tests fail with error message
- ✅ Shows "❌ Tests failed"
- ✅ Suggests "Fix the issues and try again"
- ✅ Module NOT marked as complete
- ✅ Export does NOT happen
- ✅ Can run complete again after fixes

---

### ✅ Test 3.2: Fix Tests and Re-Complete (Priority 1)

**Command**: `tito module complete 02` (with fixed test)

**Result**: ✅ PASS - Module completed successfully

**Output**:
```

**Output**:
```
🔄 Resuming Module 05: 05_autograd
💡 Continue your work, then run:
   tito module complete 05
```

**Success Criteria Met**:

- ✅ Shows valid module range
- ✅ Exit code: 1 (error)

---

### ⚠️ Test 5.2: Complete Without Prerequisites (Priority 2)

**Command**: `tito module complete 06` (when module 05 not complete)

**Result**: ⚠️ PASS with Bug - Command runs but silently fails to mark complete

**Bug Found**: Bug #3 - Complete doesn't check prerequisites (MEDIUM severity)

**Observation**:
- Tests run (wastes resources)
- Export happens (unnecessary work)
- Module not marked complete (correct outcome, but inefficient)
- No clear error message shown to user

**What Should Happen**:
Should fail early with prerequisite check, like `start` command does:
```
╭────────────────────────────── 🔒 Module Locked ──────────────────────────────╮
│ Module 06: 06_optimizers is locked                                           │
│ Complete the prerequisites first before attempting to complete this module.   │
╰──────────────────────────────────────────────────────────────────────────────╯
```

---

## Bugs Found

### 🔴 Bug #1: Reset Command Uses Wrong Directory Path (HIGH)
**Status**: ✅ FIXED
- **Files Changed**: `tito/core/config.py`, `tito/commands/module_reset.py`
- **Verification**: Reset command now works correctly

### 🔴 Bug #2: Reset Doesn't Update __init__.py Imports (HIGH)
**Status**: 🔴 OPEN - Needs Fix
- **Impact**: Resetting any module breaks imports for all other modules
- **Workaround**: Manually comment out imports in `tinytorch/__init__.py`
- **Fix Required**: Add `update_init_imports()` method to `module_reset.py`

### 🔴 Bug #3: Complete Command Doesn't Check Prerequisites (MEDIUM)
**Status**: 🔴 OPEN - Needs Fix
- **Impact**: Wastes resources running tests/export for locked modules
- **Fix Required**: Add prerequisite check at start of `complete_module()` method
- **Inconsistency**: `start` command checks prerequisites, but `complete` doesn't
