Overview

Fix ~140 clippy pedantic warnings (mostly style improvements) to improve Code Quality score from 65.4% to potentially >85%.

Current State

Code Quality: 17.0/26 (65.4%) ❌
Clippy warnings: ~140 pedantic warnings

Warning Breakdown

From earlier analysis:

• 13 unnecessary qualifications - std::result::Result → Result
• ~100 format string inlining - format!("x {}", y) → format!("x {y}")
• 2 missing Debug implementations - Add #[derive(Debug)]
• ~25 misc style improvements - Various pedantic lints

Approach

Use cargo clippy --fix to automatically fix safe warnings, then manually address remaining issues.

Phase 1: Auto-fix

cargo clippy --fix --lib --allow-dirty

Phase 2: Manual fixes

• Add Debug derives where needed
• Fix any remaining pedantic issues
• Verify all 742 tests still pass

Phase 3: Verification

cargo test --all           # All 742 tests pass
cargo clippy --lib         # Zero warnings
pmat rust-project-score    # Check improved Code Quality score

Benefits

• Code Quality improvement - From 65.4% to potentially >85%
• Rust Project Score increase - Better overall grade
• Code consistency - Modern Rust idioms throughout
• Maintainability - Cleaner, more idiomatic code

Acceptance Criteria

• All ~140 clippy warnings fixed
• All 742 unit tests passing
• All 98 doctests passing
• Code Quality score >70% (stretch: >85%)
• No new warnings introduced
