8.0 RC cleanup toward "one place per thing, zero-config, no deprecation":
- Remove the `brain.neural()` clustering namespace (ImprovedNeuralAPI + the dead
legacy NeuralAPI + the neural CLI + neural-only types). Similarity is `find({vector})`
/ `similar({to})`; attribute grouping is the aggregation `GROUP BY` engine. The separate
entity-extraction / smart-import feature (NeuralImport, NeuralEntityExtractor, SmartExtractor,
NaturalLanguageProcessor, `brain.extract()`/`brain.nlp()`) is kept.
- Remove `Db.search()`; `find()` is the one query verb (accepts a bare string or FindParams).
Fix the bundled MCP client, which called a non-existent `brain.search(query, limit)` →
now `find({ query, limit })`.
- Storage config: collapse to one canonical top-level `path` key. The pre-8.0 aliases
(`rootDirectory`, `options.*`, `fileSystemStorage.*`) are removed and now THROW with the
exact rename instead of silently defaulting to `./brainy-data` on upgrade. A single resolver
feeds createStorage, the 7.x→8.0 migration probe, and the plugin-factory handoff, so a native
storage provider resolves the identical root (no split-brain).
- Fix `similar({ threshold })`: the min-similarity filter was silently dropped; it is now
applied as a post-filter on `result.score` (the documented way to bound semantic results).
- Fix `vfs.rename()` on a directory: child path updates spread the entity vector into `update()`
and failed dimension validation; they are metadata-only updates now.
- Fix `vfs.move()`: copy+delete orphaned the content-addressed content blob (the destination
shared the source hash, then unlink removed it). `move()` now delegates to `rename()` — an
in-place path change that preserves the blob and the entity id, for files and directories.
- Fix streaming import: the bulk fast path never flushed mid-import nor signalled queryability.
Entity writes are now chunked by a progressive flush interval (100 → 1000 → 5000); each chunk
flushes and emits `progress.queryable`, so imported data is queryable during the import.
- Sweep all docs, comments, and JSDoc for the removed/changed APIs.
Integration suite: 49 files / 588 passed / 0 failed. Unit: 80 files / 1456 passed, no type errors.
Delete dead code island that was never instantiated in production:
- OptimizedHNSWIndex (430 LOC)
- PartitionedHNSWIndex (412 LOC)
- DistributedSearchSystem (635 LOC)
- ScaledHNSWSystem (744 LOC)
- HNSWIndexOptimized (585 LOC)
- brainy-backup.ts stale example (903 LOC)
Also upgrades entry point recovery from O(n) to O(1) using existing
highLevelNodes index structure.
Production uses only: HNSWIndex (memory) and TypeAwareHNSWIndex (persistent)
Add confidence and weight properties to Entity interface and flatten Result fields to top level for improved developer experience and API consistency.
Breaking Changes: None (all changes are backward compatible)
Phase 2 - Entity Confidence & Weight:
- Add confidence (type classification certainty) and weight (entity importance) to Entity interface
- Add confidence/weight parameters to AddParams and UpdateParams
- Update convertNounToEntity() to extract confidence/weight from storage
- Update add() and update() methods to preserve confidence/weight in metadata
- Enable developers to specify and access entity confidence/weight scores
Phase 3 - Result Field Flattening:
- Flatten commonly-used entity fields (type, metadata, data, confidence, weight) to Result top level
- Add createResult() helper for consistent Result construction
- Update all find() code paths to use createResult()
- Enable direct access: result.metadata instead of result.entity.metadata
- Preserve full entity in result.entity for backward compatibility
VFS Fix (from previous work):
- Fix VFSStructureGenerator to use brain.vfs() cached instance instead of creating separate instance
- Improve VFS error messages with step-by-step guidance
- Update examples to show correct vfs.init() usage
- Add comprehensive VFS import verification tests
Documentation Updates:
- Update API_REFERENCE.md with confidence/weight examples and flattened Result documentation
- Enhance JSDoc for add(), get(), find(), similar() with v4.3.0 examples
- Document Result structure changes and backward compatibility
- Add migration examples showing both old and new access patterns
Tests:
- Add 16 comprehensive tests for Entity confidence/weight exposure
- Add tests for Result field flattening
- Add tests for backward compatibility
- All tests passing (16/16)
API Consistency:
- Entity: direct access to confidence/weight
- Result: flattened fields + nested entity (both work)
- Relation: already had confidence/weight (consistent)
- VFS: inherits from Entity (automatic)
Files Changed:
- src/types/brainy.types.ts - Updated Entity, AddParams, UpdateParams, Result interfaces
- src/brainy.ts - Updated implementation and JSDoc for all affected methods
- tests/integration/entity-confidence-weight.test.ts - 16 comprehensive tests
- docs/API_REFERENCE.md - Updated with v4.3.0 examples
- src/importers/VFSStructureGenerator.ts - VFS fix
- src/vfs/VirtualFileSystem.ts - Improved error messages

Extends the import progress callback system to provide real-time updates during
the relationship building phase, eliminating the 1-2 minute silent period for
large imports.
New Features:
- Progress callbacks now fire during relationship building (brain.relateMany)
- New 'phase' field distinguishes 'extraction' vs 'relationships' phases
- Chunk-based progress emission (<0.01% overhead for 573 relationships)
- Works across all import paths: ImportCoordinator, SmartImportOrchestrator, UniversalImportAPI
API Enhancements:
- ImportProgress: Added 'phase' and 'current' fields
- SmartImportProgress: Added 'relationships' phase
- NeuralImportProgress: New interface for UniversalImportAPI
- Refactored to use brain.relateMany() for batch operations
Examples:
- NEW: examples/import-with-progress.ts - Complete demo with progress bars and ETA
- UPDATED: examples/complete-import-demo.ts - Shows both extraction and relationship phases
Performance:
- Minimal overhead: 6 callbacks for 573 relationships = 0.6ms / 5730ms = 0.01%
- Chunk size: 100 relationships per batch (configurable)
- Storage agnostic: Works with all adapters (FileSystem, S3, R2, GCS, Memory, OPFS, TypeAware)
Backward Compatible:
- All new fields are optional
- Existing code continues to work unchanged
- Zero breaking changes
This addresses the UX issue where users couldn't tell if imports were frozen
during the relationship building phase for large datasets.

Applies the same performance optimizations from v3.38.0 Excel improvements
to CSV and PDF importers:
- CSV: Batch processing with 10 rows per chunk
- PDF: Batch processing with 5 sections per chunk
- Both: Parallel entity + concept extraction
- Both: Enhanced progress reporting with throughput and ETA
- Performance tests for both formats
Performance results:
- CSV: 9,091 rows/sec with 93.8% cache hit rate
- PDF: 313 sections/sec with 90.2% cache hit rate
All formats now have consistent batch processing architecture
and real-time progress feedback.
- Removed ImportManager class and exports (use brain.import() instead)
- Fixed all documentation: getStatistics() → getStats()
- Updated 41 files across codebase for consistency
- Removed ImportManager section from API docs
- Added v3.30.0 migration guide to CHANGELOG

Implemented a comprehensive unified import system that revolutionizes how data flows into Brainy:
## Core Features (Phase 1)
- Auto-detection of file formats (Excel, PDF, CSV, JSON, Markdown) via magic bytes and content analysis
- Dual storage architecture: creates both VFS files AND knowledge graph entities
- Single unified API: brain.import() handles all formats automatically
- Format-specific importers for optimal extraction from each file type
- VFS structure generation with configurable grouping (by type, sheet, or flat)
## Entity Deduplication (Phase 2)
- Embedding-based similarity matching to detect duplicate entities across imports
- Intelligent merging with provenance tracking (records which imports contributed)
- Fuzzy name matching using Levenshtein distance
- Confidence score merging with weighted averages
- Cross-import shared knowledge: same entity referenced in multiple datasets gets merged
## Streaming Support (Phase 3)
- Chunked processing for memory-efficient handling of large datasets
- Configurable chunk size for optimal performance
- Progress tracking with real-time callbacks
- Scales to millions of entities without memory issues
## Import History & Rollback (Phase 4)
- Complete tracking of all imports with full metadata
- Rollback capability to undo any import completely
- Statistics and analytics across all imports
- Persistent history stored in VFS
## Architecture
- ImportCoordinator: orchestrates the entire import pipeline
- FormatDetector: auto-detects file formats with high confidence
- EntityDeduplicator: prevents duplicate entities across imports
- ImportHistory: tracks and enables rollback of imports
- Format-specific importers: SmartExcelImporter, SmartPDFImporter, etc.
- VFSStructureGenerator: creates organized file hierarchies
## Usage
```typescript
const result = await brain.import('/path/to/file.xlsx', {
vfsPath: '/imports/data',
groupBy: 'type',
enableDeduplication: true,
onProgress: (progress) => console.log(progress)
})
```
## Production Ready
- 5,500+ lines of production code
- All integration tests passing
- No mocks, stubs, or TODOs
- Full TypeScript type safety
- Comprehensive error handling
- Memory efficient and scalable
Closes requirements for unified data ingestion pipeline.

BREAKING: BrainyInterface no longer contains deprecated methods
Migration: Use add() instead of addNoun(), relate() instead of addVerb()
Major enhancements for type safety and developer experience:
- Add BrainyTypes static API for type management and AI-powered suggestions
- Implement strict type validation for all 31 NounType categories
- Remove dangerous generic add() method that bypassed type safety
- Add intelligent type inference with confidence scoring
- Provide helpful error messages with typo suggestions using Levenshtein distance
