1. Repository Structure

• 1.1 Introduce src/lib.rs, keep src/main.rs as a thin binary wrapper, and preserve existing module boundaries so integration tests can import the crate cleanly
• 1.2 Move integration-only helpers out of production modules into tests/support/ and remove the unused src/tests direction so the test layout is unambiguous
• 1.3 Add top-level integration tests under tests/ that exercise at least diagnostics, window enumeration, and daemon startup/recovery flows through the library target

2. Local Validation Tooling

• 2.1 Add one documented local validation entrypoint for formatting, linting, unit tests, integration tests, and site formatting checks
• 2.2 Add a root .pre-commit-config.yaml that standardizes on pre-commit for fast commit-time checks without introducing a root Node workflow
• 2.3 Keep formatting configuration minimal by using default rustfmt, reusing the existing site-local Prettier setup, and only adding new config where implementation requires it

3. CI Hardening

• 3.1 Update GitHub Actions to validate pull requests in addition to main pushes and to run the same validation categories contributors run locally
• 3.2 Add an explicit Xvfb-backed CI lane that runs the integration tests covering diagnostics, window enumeration, and daemon recovery behavior
• 3.3 Ensure CI also runs the repository's formatting, clippy, unit test, and site formatting checks through the shared local entrypoints where practical

4. Documentation

• 4.1 Update contributor-facing docs to explain the new crate/test layout, including where integration tests and shared helpers live
• 4.2 Document the local validation workflow and pre-commit installation/use so contributors can reproduce CI expectations locally
• 4.3 Update the Phase 2 planning/docs references so the repo-quality foundation clearly lands before later packaging and distribution phases
