 ## Guidelines
 
-- **Tests**: Use Deno's built-in test framework. New tests go next to the code (`src/**/*.test.ts`) or in `test/`; shared fixtures go in `test/assets/`. Every `*.test.ts` file must be committed (enforced by `scripts/tracked-tests.test.ts`).
-- **Server code**: Organized around SBP selectors (`@sbp/sbp`) with several database backends; see `src/serve/` and `src/validateConfig.ts`.
