501244398e **feat(core, storage, tests): enhance verb construction with timestamps and metadata**
- **Core**: Improved verb creation logic by adding `createdAt`, `updatedAt`, and `createdBy` attributes. These fields include timestamped metadata (`seconds`, `nanoseconds`) and source augmentation/service information for better tracking.
- **Storage**: Refactored `BaseStorage` methods to utilize internal variants (e.g., `saveVerb_internal`, `getNoun_internal`). Added support for new verb attributes while maintaining backward compatibility with existing data structures.
- **Tests**:
  - Updated `s3-storage.test.ts` and `opfs-storage.test.ts` to validate changes in verb attributes such as timestamps and augmentation metadata.
  - Added assertions for `createdAt`, `updatedAt`, and `createdBy` fields in test cases.
- **Cleanup**: Replaced ambiguous type aliases like `Edge` and `HNSWNode` with clearer equivalents (`Verb` and `HNSWNoun_internal`) for consistency across storage adapters.

**Purpose**: Enhance metadata tracking and standardize attribute handling across storage and core modules to ensure accurate and consistent data throughout the system.

bc480770b5 **feat(core, statistics, storage): enhance service-level statistics tracking and result filtering**
- **Core**: Introduced a `getCurrentAugmentation` method for detecting active augmentation names. Updated metadata handling to include `createdBy`, `createdAt`, and `updatedAt` attributes for improved tracking.
- **Storage**: Added support for service-based statistics tracking with new methods such as `incrementStatistic`, `decrementStatistic`, and `updateHnswIndexSize`. Implemented persistence for statistics in storage adapters.
- **Statistics**: Enhanced `getStatistics` functionality to provide service-specific breakdowns and support filtering by services. Improved noun, verb, and metadata tracking mechanisms.
- **Search**: Added `service` option to filter results during searches for nouns, verbs, and metadata, ensuring accurate service-based query results.
- **Refactor**: Simplified search logic by integrating HNSW index filtering for better performance when retrieving service-specific results.
- **Tests**: Added comprehensive test coverage for service-level statistics and filtering by service.

**Purpose**: Improve service-level data tracking and analytics while enhancing functionality for filtering and maintaining metadata accuracy to support detailed insights for diverse use cases.

68247c9a6c **feat(storage): remove FileSystemStorage and OPFSStorage implementations**
- **Removal**: Deleted `FileSystemStorage` and `OPFSStorage` adapters from the `/storage` directory.
- **Refactor**: Simplifies the codebase by eliminating unused, redundant, or outdated storage implementations.
- **Impact**: Ensures maintainability by focusing on actively supported storage solutions.

**Purpose**: Streamline the project by removing deprecated or unused storage adapters, reducing complexity and maintenance overhead.

85e5a6bfb9 **feat(core, storage, tests): add service-level statistics tracking and storage adapter enhancements**
- **Core**: Enhanced `getStatistics` function to support `service` and `service[]` filters, enabling statistics breakdown by service. Modified return structure to include `serviceBreakdown` for detailed insights.
- **Storage**: Implemented a new `BaseStorageAdapter` abstract class to centralize statistics-related functionality, such as incrementing/decrementing counters and updating HNSW index size. Refactored all storage adapters (`FileSystemStorage`, `S3CompatibleStorage`, `MemoryStorage`, `OPFSStorage`) to extend `BaseStorageAdapter`, ensuring consistent statistics tracking.
- **Tests**: Added new test cases in `statistics.test.ts` to validate service-level statistics tracking, breakdown accuracy, and multi-service filtering.

**Purpose**: Improve insight into data trends by tracking service-specific usage in statistics. Enhance maintainability and consistency through storage adapter centralization and robust testing.
