 - [x] Test uploads without authentication
-- [x] Test uploads with valid nostr auth
-- [x] Test uploads with invalid auth
-- [x] Test hash mismatch scenarios
+- [x] Test uploads with valid nostr auth ✅ **WORKING** (HTTP 200 success)
+- [x] Test uploads with invalid auth ✅ **WORKING** (proper error responses with specific error types)
+- [x] Test hash mismatch scenarios ✅ **WORKING** (409 Conflict responses)
 - [ ] Test file size limits
 - [x] Verify blob descriptors are correct
 - [x] Verify database metadata storage (uploader_pubkey and filename)

 - [ ] Memory safety in C implementation
 - [ ] Proper error message sanitization
 - [ ] Log security (no sensitive data)

+- [x] **API Refactoring Complete** - Upgraded from low-level crypto headers to high-level `nostr_crypto_init()` API
+- [x] **Enhanced Error Messages** - Specific error types: event_expired, invalid_signature, invalid_pubkey, etc.
 - [ ] **Upload DOS vulnerability** - Current implementation vulnerable to memory exhaustion attacks
