Search for illegal imports between layers 2. Verify no external libs in domain/application 3. Check that adapters implement port interfaces 4. Verify use cases use DI via providers.ts ## Useful Commands ```bash # Search for adapter imports in application grep -r "from.*adapters" packages/core/src/application/ # Search for external lib imports in domain grep -r "from.*@garmin\|fast-xml-parser" packages/core/src/domain/ ``` Report violations with file paths and specific imports. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/pablo-albaladejo) — claim your Tome and manage your conversions.
