# 13: Post Cleanup

## Overview

Final build verification. Run after all other migrations are processed.
This is a fresh codebase — there is no legacy code to remove.

## Instructions

Run `cargo build --release` repeatedly until it builds without any
warnings or errors.

If there are unused code paths, remove them. If there are missing
implementations referenced by other modules, implement them or remove
the references.

Ensure all modules compile cleanly:
- No dead code warnings
- No unused import warnings
- No unused variable warnings
- No deprecated API usage

Run `cargo test` and fix any test failures.

## Acceptance Criteria

- [ ] `cargo build --release` succeeds with zero warnings and zero errors
- [ ] `cargo test` passes
- [ ] No dead code, unused imports, or unused variables remain
