/// Letter grade (A+ to F)
pub grade: Grade,
/// Breakdown by category
pub categories: CategoryScores,
/// Actionable recommendations
pub recommendations: Vec<Recommendation>,
/// Metadata (timestamp, project, version)
pub metadata: ScoreMetadata,
/// Score velocity (Kaizen tracking)
pub velocity: Option<ScoreVelocity>,
}
```
**2. CategoryScores**
```rust
/// Six scoring categories (106 points total)
pub struct CategoryScores {
/// Rust tooling compliance (25pts)

pub enum Grade {
APlus, // 95-106 (89.6%+)
A, // 90-94 (84.9%-89.5%)
AMinus, // 85-89 (80.2%-84.8%)
BPlus, // 80-84 (75.5%-80.1%)
B, // 70-79 (66.0%-75.4%)
C, // 60-69
D, // 50-59
F, // 0-49
}
```
**4. ScoreVelocity** (NEW in v1.1)
```rust
/// Kaizen: Continuous improvement tracking
pub struct ScoreVelocity {
/// Current score
pub current: f64,
/// Previous score (from baseline)
pub previous: f64,
/// Change in points
pub delta: f64,
/// Change as percentage
pub delta_percent: f64,
/// Days since baseline
pub days_elapsed: u64,
/// Points per day improvement rate
pub points_per_day: f64,
/// Most improved category
pub most_improved: Option<String>,
/// Projected days to next grade
pub days_to_next_grade: Option<u64>,
}
```

## Evidence-Based Decisions (Peer-Reviewed Research)
**Key Academic Findings Driving Implementation**:
1. **Complexity Weight Reduced** (8pts → 3pts)
- **Source**: arXiv 2024 - "An Empirical Investigation of Correlation between Code Complexity and Bugs"
- **Finding**: "No correlation between complexity and presence of bugs"
- **Impact**: Shifted weight to empirically-proven indicators
2. **Unsafe Code Weight Increased** (6pts → 9pts)
- **Rationale**: Memory safety is Rust's core value proposition
- **Impact**: Emphasizes proper `unsafe` documentation + safety comments
3. **Mutation Testing Weight Increased** (5pts → 8pts)
- **Source**: ICST 2024 Mutation Workshop - "Mutation Testing in Practice"
- **Finding**: Developers find mutation testing highly valuable for test quality
- **Impact**: Now a significant quality indicator
4. **Clippy Tiered Scoring** (NEW in v1.1)
- **Source**: 2023 - "Unleashing the Power of Clippy in Real-World Rust Projects"
- **Finding**: Pedantic lints have high false positive rate
- **Impact**: Differentiate correctness > suspicious > pedantic
5. **Build Time as Metric** (NEW 4pts)
- **Rationale**: Direct developer productivity impact
- **Impact**: Fast builds enable rapid iteration (Kaizen)
## Next Actions
### Immediate (Next Session)
1. **Create RED tests** (`server/tests/rust_project_score_tests.rs`)
2. **Verify tests FAIL** (compilation errors expected)
3. **Create minimal type stubs** to make tests compile
4. **Run tests** and verify RED phase complete
### Sprint 1 Completion (This Week)
1. Implement core types (GREEN phase)
2. Refactor and optimize
3. Add property-based tests
4. Achieve ≥85% coverage for core types
### Sprint 2-4 (Next 2 Weeks)
Follow roadmap systematically through remaining sprints.

## Sprint 3: CLI Integration - COMPLETE ✅
**Date Completed**: 2025-11-16
**Status**: Implementation complete, dogfooding bug discovered and fixed
### Components Delivered
1. **CLI Command** (`src/cli/commands.rs:456-478`)
- Command: `rust-project-score` (alias: `rust-score`)
- Parameters: `--path`, `--format`, `--verbose`, `--failures-only`, `--output`
2. **Handler** (`src/cli/handlers/rust_project_score_handlers.rs` - NEW FILE, 400+ lines)
- Validation: Path exists, is directory, has Cargo.toml
- Integration: RustProjectScoreOrchestrator
- Output formats: Text (colored), JSON, Markdown, YAML
3. **Integration Points**
- Command Dispatcher: `src/cli/command_dispatcher.rs:261-270`
- Unified Protocol: `src/unified_protocol/adapters/cli.rs` (lines 108, 1777)
- Command Structure: `src/cli/command_structure.rs:368-383`
- Module Exports: `src/cli/handlers/mod.rs` (lines 60, 130)
### Dogfooding Bug Discovery 🐛
**Bug**: OOM (Out of Memory) during `pmat rust-project-score --path .`
**Root Cause** (`code_quality_scorer.rs:41`):
```rust
// BEFORE (BROKEN):
Command::new("cargo")
.arg("run")
.arg("--bin")
.arg("pmat") // Recursive execution!
```
**Problem**: Recursive cargo execution → build lock contention → memory explosion
**Fix Applied**:
```rust
// AFTER (FIXED):
Command::new("pmat") // Use binary directly
.arg("analyze")
.arg("complexity")
```
**Fallback**: Uses `score_complexity_simple()` heuristic if binary not available
### Lessons from Dogfooding (Toyota Way - Genchi Genbutsu)
1. ✅ **Always test on your own codebase** - Found critical bug immediately
2. ✅ **Avoid recursive tool invocation** - Use binaries, not `cargo run`
3. ✅ **Implement graceful fallbacks** - Heuristics when binary unavailable
4. ✅ **Memory-aware design** - Large projects require careful resource management
### CLI Usage
```bash
# Basic usage
pmat rust-project-score
# Specific path with JSON output
pmat rust-project-score --path /path/to/rust/project --format json
# Verbose breakdown
pmat rust-project-score --verbose --output score-report.md --format markdown
```

- `panic = "abort"` for smaller binaries (release): 2pts
- `[profile.dev]` with `panic = "abort"` (faster testing): 2pts
- **Penalty**: -3pts if LTO in dev/test profiles (slows TDD loop)
**Academic Foundation**:
- Beller et al. 2017 MSR: Builds >10min correlate with 42% fewer local test runs
**Tests**: 6 comprehensive tests including full score, partial scores, penalty scenarios
#### ✅ Phase 6: Performance & Benchmarking Alignment
**Commit**: `0d23b401` - "refactor(rust-score): Align PerformanceScorer with Learn from Rust Giants spec"
**Implementation**: `performance_scorer.rs` - Simplified and aligned with specification
**Changes**:
- Simplified `score_benchmarks()` to check `[[bench]]` sections only (5pts)
- Added `score_benchmark_ci()` for CI workflow detection (3pts)
- Added `score_custom_harness()` for `harness = false` detection (2pts)
- Removed legacy profiling-based scoring (not in spec)
**Tests**: Verified against 10-point target from specification
