Review implementation against plan

Review current implementation against documented plan

Verifying that coded changes match the documented implementation plan before committing

• · docs/implementation-plan.md with completed tasks
• · Current codebase in src/

• · Test results (cargo test output)
• · Linting results (cargo clippy warnings)
• · Formatting check results (cargo fmt)
• · Task completion summary (done vs pending)

• · Bash (cargo test, cargo clippy, cargo fmt, cargo build)

• · docs/implementation-plan.md file exists
• · Rust project with Cargo.toml
• · cargo installed and in PATH

• · Implementation plan not found
• · cargo not available
• · Tests or clippy checks fail with errors

• · Runs full test suite (not just linting)
• · Enforces clippy warnings (high bar for code quality)
• · Compares plan tasks against actual src/ code
• · Reports deviations from plan explicitly
