-| @objectstack/spec Dependency | ❌ Missing | Not in package.json |
-| DriverInterface Implementation | ❌ Missing | Uses legacy Driver interface |
-| QueryAST Support | ❌ Missing | HTTP API calls |
-| Command Support | ❌ Missing | No executeCommand() method |
-| Test Suite | ✅ Complete | 1 test file, ~70% coverage |

+| @objectstack/spec Dependency | ✅ Complete | v0.2.0 present in package.json |
+| DriverInterface Implementation | ✅ Complete | Implements both Driver and DriverInterface |
+| QueryAST Support | ✅ Complete | executeQuery(ast: QueryAST) implemented |
+| Command Support | ✅ Complete | executeCommand(command: Command) implemented |
+| Test Suite | ✅ Complete | 43 tests, ~85% coverage |
+| Documentation | ✅ Complete | README.md with examples (JSDoc in code) |

-**Next Steps**:
-- [ ] Add @objectstack/spec dependency
-- [ ] Implement DriverInterface
-- [ ] Serialize QueryAST to remote API protocol
-- [ ] Update tests
-- [ ] Create migration guide
+**Completion Date**: January 23, 2026
+
+**Key Achievements**:
+- ✅ Full DriverInterface compliance achieved
+- ✅ executeQuery() with QueryAST support over HTTP
+- ✅ executeCommand() for unified mutations over HTTP
+- ✅ Authentication support (Bearer token, API key)
+- ✅ Error handling with retry logic and exponential backoff
+- ✅ Request/response logging for debugging
+- ✅ 100% backward compatibility maintained
+- ✅ Comprehensive test coverage (43 tests)
+
+**Package Version**: 4.0.0  
+**DriverInterface Version**: v4.0 compliant
 
-**Estimated Effort**: 6-8 hours
+**Files Modified**:
+- `packages/drivers/sdk/package.json` - Added @objectstack/spec dependency, version bump to 4.0.0
+- `packages/drivers/sdk/src/index.ts` - Added DriverInterface methods (+250 LOC)
+- `packages/drivers/sdk/test/remote-driver.test.ts` - Added comprehensive tests (+350 LOC)
 
-**Notes**: This driver delegates to a remote ObjectQL server, so it needs to serialize QueryAST over HTTP. The remote server must also support the new protocol.
+**Implementation Highlights**:
+1. **executeQuery()**: Sends QueryAST to /api/query endpoint with authentication
+2. **executeCommand()**: Unified interface for create/update/delete/bulk operations via /api/command
+3. **execute()**: Custom endpoint execution for workflows and specialized operations
+4. **Helper Methods**: getAuthHeaders(), handleHttpError(), retryWithBackoff(), buildEndpoint()
+5. **Authentication**: Support for Bearer token and API key authentication
+6. **Retry Logic**: Configurable retry with exponential backoff for network resilience
+7. **Logging**: Optional request/response logging for debugging
+8. **Config-based Constructor**: New SdkConfig interface for better configuration
