 - **Integrity verification**: SHA256 on every operation
 - **Local caching**: Fast repeated operations
 - **Zero dependencies**: No database, no manifest files
+- **Modular storage**: The storage layer is pluggable - you could easily replace S3 with a filesystem driver (using extended attributes for metadata) or any other backend
+
+The codebase follows a ports-and-adapters pattern where core business logic is decoupled from infrastructure, with storage operations abstracted through well-defined interfaces in the `ports/` directory and concrete implementations in `adapters/`.
