**GitHub Issue**: https://github.com/paiml/ruchy/issues/78

**Content**:
- Executive summary for Ruchy programming language project
- 5-step integration process
- Expected results (50-200 files, 85-95 avg score)
- Configuration recommendations (3 phases: learning, adjustment, enforcement)
- CI/CD integration details
- 6-week migration timeline

**Key Recommendations**:
- Start with `B+` minimum grade
- Warning mode for 2-4 weeks
- Strict mode after team adjustment
- Max 5-point score drop tolerance

#### Report 2: bashrs (326 lines)

- bashrs-specific quality focus areas (parser, linter rules, safety checks)
- Module-specific quality targets
- Integration with bashrs workflow
- Predicted grade distribution
- 4-week migration timeline

**Special Considerations**:
- Parser complexity expected (target: B+ minimum)
- Linter rules should be simple (target: A minimum)
- Safety checks critical (target: A or A+ grade)
- Zero tolerance for regressions in safety code

#### Report 3: RuchyRuchy (326 lines)

- Future: TDG analysis of Ruchy language code (requires Ruchy parser)

**bashrs** (shell safety linter):
- TDG enforcement for bashrs Rust codebase
- bashrs lints shell scripts, PMAT TDG grades bashrs code
- Full-stack quality: bash scripts + Rust implementation

**RuchyRuchy** (Ruby-to-Ruchy transpiler):
- TDG enforcement for transpiler quality
- Integrates with Ruchy and bashrs ecosystem
- Multi-language quality (Ruby input, Ruchy output, Rust impl)

## Lessons Learned

### 1. Integration Reports are Valuable

**Discovery**: Project-specific integration guides significantly lower adoption barriers.

**Impact**: Users have clear, actionable paths to integrate TDG enforcement rather than generic "read the docs" guidance.

**Future**: Apply same template to other PMAT features (mutation testing, deep context, etc.)

### 2. Consistent Documentation Style Works

**Discovery**: Using same detailed, tutorial-based style across pmat-book and integration reports creates cohesive documentation.

**Impact**: Users get consistent experience whether reading book or integration reports.

**Future**: Maintain this style for all future documentation.

### 3. Real-World Examples are Essential

**Discovery**: Sprint 67 dogfooding provided concrete examples (851 files, 93.0 avg score, grade distribution).

**Impact**: Users see realistic expectations, not theoretical claims.

**Future**: Always include real-world data in documentation.

## Next Steps

**Immediate** (Sprint 70):
- Option 1: Implement cargo-mutants wrapper (mutation testing enhancement)
- Option 2: Create TDG Dashboard (web-based visualization)
- Option 3: Additional pmat-book chapters (deep context, quality gates, etc.)

**Recommended**: Proceed with Sprint 70 - cargo-mutants wrapper (mutation testing validated as 0% effective, needs fix)
