- **Tests**: Added new `statistics-storage.test.ts` to validate statistics storage functionality across scenarios including saving, retrieving, time-based partitioning, and backward compatibility. Ensured tests dynamically handle missing environment variables by skipping S3-related tests when credentials are unavailable.
- **Docs**: Enhanced `statistics.md` with detailed explanations of scalability improvements, including adaptive flush timing, batched updates, and time-based partitioning. Improved readability and structure.
- **Storage**: Updated all storage adapters to integrate time-based partitioning and maintain backward compatibility with legacy statistics storage formats.
- **Dependencies**: Added `dotenv` to support environmental variable management for storage adapter tests.
**Purpose**: Strengthen system reliability by adding comprehensive test coverage for statistics storage, improve scalability documentation, and ensure consistency across storage adapters with robust implementations.
- **Core Improvements**:
- Refactored logging functions into a unified `logger` method for consistent output across the library.
- Enabled the `forceMemoryStorage` option in `BrainyData` initialization for improved storage flexibility in tests and specific use cases.
- **TensorFlow.js and Environment Updates**:
- Clarified the dependency structure in `README.md` to emphasize bundled dependencies and remove legacy peer dependency instructions.
- Simplified and reformatted environment detection logic for better maintainability and readability.
- **Testing Enhancements**:
- Added `tests/package-size-limit.test.ts` to monitor and validate npm package size against defined thresholds.
- Updated `tests/environment.node.test.ts` and core tests to leverage `forceMemoryStorage` for better test setup standardization.
- Improved test isolation with expanded `globalThis` utility definitions and cleanup logic.
- **Documentation**:
- Added detailed best practices for debugging and organizing tests in `DEVELOPERS.md`.
- Removed outdated installation hints from `package.json` and streamlined scripts by including `test:size` for package size validation.
**Purpose**: These changes unify core logging mechanisms, expand configurability of storage options, and improve testing reliability and coverage. Documentation and clarity are enhanced to align with updated functionality and best practices.
