# QA Fixes Summary

## Fixes Applied (2025-01-22)

### 1. Dead Code Analysis - Fixed ✅
**Issue**: Reporting 0 files analyzed
**Root Cause**: `DeadCodeSummary::from_files()` was calculating total_files_analyzed from dead code files only
**Fix**: Track total project files separately and update summary after calculation
```rust
// In dead_code_analyzer.rs
let total_files_in_project = project_context.files.len();
// ... analysis ...
summary.total_files_analyzed = total_files_in_project;
```

### 2. Scaffold Command - Fixed ✅
**Issue**: Reports success but creates no files
**Root Cause**: No default templates when none specified, poor error handling
**Fix**: Added default template selection and file creation feedback
```rust
// In generation_handlers.rs
let templates_to_use = if templates.is_empty() {
    match toolchain.as_str() {
        "rust" => vec!["makefile", "readme", "gitignore"],
        "deno" => vec!["makefile", "readme", "gitignore"],
        "python-uv" => vec!["makefile", "readme", "gitignore"],
        _ => vec!["readme"],
    }
} else {
    templates
};
```

### 3. Incremental Coverage - Fixed ✅
**Issue**: "No such file or directory" error
**Root Cause**: Mock implementation returning fake file paths
**Fix**: Replaced with actual git diff command
```rust
// In coverage_helpers.rs
let output = Command::new("git")
    .arg("diff")
    .arg("--name-status")
    .arg(&format!("{}...{}", base_branch, target))
    .current_dir(project_path)
    .output()
    .await?;
```

### 4. DAG --target-nodes Parameter - Fixed ✅
**Issue**: Parameter not recognized
**Root Cause**: Missing from command structure
**Fix**: Added to commands.rs and all handlers
```rust
// In commands.rs
/// Target number of nodes (applies graph reduction if exceeded)
#[arg(long)]
target_nodes: Option<usize>,
```

### 5. Stub Implementations - Fixed ✅
**Issue**: Silent failures with no user feedback
**Fix**: Added user-friendly messages to all stubs
```rust
eprintln!("🚧 {} is not yet implemented in this version.", feature_name);
eprintln!("This feature will be available in a future release.");
```

### 6. Makefile Quality Score - Fixed ✅
**Issue**: Shows 0% quality despite no violations
**Root Cause**: Rules parameter defaults to "all", filtering out all violations
**Fix**: Check for "all" in filter logic
```rust
let filtered_violations = if rules.is_empty() || rules == vec!["all"] {
    lint_result.violations.clone()
} else {
    // ... filtering logic
};
```

## Build Instructions

Due to compilation taking time, use:
```bash
cargo build --release --bin pmat
```

## Testing

Run the QA retest script after build completes:
```bash
./scripts/qa-retest.sh
```

## Status
All code fixes have been applied. Waiting for build to complete to verify with full QA checklist.
