# Pre-Release Verification Run the complete verification suite before a release. ## Steps 1. Run `composer lint:all` — all linters must pass (PHPCS, EditorConfig, markdownlint) 2. Run `composer test` — all tests must pass 3. Run `composer build` — PHAR must build successfully 4. Run `builds/branch-usage-checker --version` — smoke test the PHAR 5. Run `git status` — working tree should be clean (no uncommitted changes) 6. Report go/no-go summary with results of each step
