## Development

- [Architecture Overview](https://raw.githubusercontent.com/openscan-explorer/explorer/8ccaa3283333eb4616efe3255398a77ca6d6ef93/.claude/rules/architecture.md): OpenScan follows a layered architecture with clear separation between data fetching, transformation, and presentation:
- [Testing](https://raw.githubusercontent.com/openscan-explorer/explorer/8ccaa3283333eb4616efe3255398a77ca6d6ef93/.claude/rules/testing.md): OpenScan has two test layers: Vitest for unit tests and Playwright for end-to-end browser tests against a real Vite dev server. Most test commands also live in commands.md; this file documents the *model* — projects, suites, mocking, and CI mapping — so future test work lands in the right place.
- [Git Workflow and Collaboration](https://raw.githubusercontent.com/openscan-explorer/explorer/8ccaa3283333eb4616efe3255398a77ca6d6ef93/.claude/rules/workflow.md): The project uses two workflows depending on the scope of changes:
