Add a write-time incremental aggregation engine that maintains running
totals on every add/update/delete for O(1) read performance. Integrates
into brain.find({ aggregate }) for a unified query API.
Core features:
- AggregationIndex with defineAggregate()/removeAggregate() API
- Five aggregation operations: SUM, COUNT, AVG, MIN, MAX
- GROUP BY with multiple dimensions including time windows
- Time window bucketing: hour, day, week, month, quarter, year, custom
- Materialization of results as NounType.Measurement entities
- Debounced persistence of definitions and state to storage
- Definition change detection via FNV-1a hashing with auto-rebuild
- Infinite loop prevention for materialized entities
- 'aggregation' plugin provider key for native acceleration
- Lazy initialization (created on first defineAggregate() call)
- 73 tests (unit + integration) covering all functionality

Fix critical wiring bugs that prevented plugin-provided implementations
from being used at runtime. All CRUD operations, fork/checkout/clear,
batch embedding, neural APIs, and VFS path resolution now properly
dispatch through the plugin registry.
Changes:
- Wire graphIndex to storage for getVerbsBySource() fast path
- Replace instanceof checks with duck-typing (indexIsTypeAware flag)
so plugin HNSW indexes work in add/update/delete/search
- Add createIndex() shared helper for plugin HNSW factory
- Fix fork/checkout/clear to use plugin factories for metadataIndex,
graphIndex, and HNSW instead of hardcoding JS constructors
- Add three-tier embedBatch priority: embedBatch > embeddings > WASM
- Skip WASM warmup/eagerEmbeddings when plugin provides embeddings
- Fix PathResolver metadataIndex access (was looking on storage)
- Use global UnifiedCache in SemanticPathResolver
- Wire plugin distance function through neural APIs
- Add diagnostics() method and CLI command for provider inspection
- Add requireProviders() for production fail-fast assertions
- Add init-time provider summary log
- Add plugin developer documentation (docs/PLUGINS.md)
- Export DiagnosticsResult type
The __words__ keyword index stores 50-5000 entries per entity (one per
word), which inflated avg entries/entity well above the corruption
threshold of 100. This caused:
1. validateConsistency() to falsely detect corruption on every startup,
triggering unnecessary clearAllIndexData() + rebuild() cycles
2. getStats() to log false "Metadata index may be corrupted" warnings
and report inflated totalEntries/totalIds stats
Both methods now skip __words__ when counting, so stats and health
checks reflect metadata fields only (noun, type, createdAt, etc.).
Keyword search is unaffected since the __words__ field index itself
is not modified.
- Add native config option: `new Brainy({ integrations: true })`
- OData integration for Excel Power Query and Power BI
- Google Sheets integration with Apps Script
- Server-Sent Events (SSE) for real-time streaming
- Webhooks for push notifications
- Zero-config with sensible defaults
- Full tree-shaking when disabled
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)
- 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
Co-Authored-By: Claude <noreply@anthropic.com>
Resolves API accessibility issues reported by Brain Cloud Studio team:
1. Export ImportManager and createImportManager
- ImportManager class was fully implemented but not exported
- Consumers can now access AI-powered import features
- Includes ImportOptions and ImportResult types
2. Add brain.getStats() convenience method
- Documentation showed getStats() as top-level method
- Implementation had it nested under brain.counts.getStats()
- Added convenience method that delegates to counts API
- Maintains backward compatibility
3. Update API documentation
- Corrected getStats() signature and return type
- Added comprehensive ImportManager documentation
- Included examples for all import patterns
These changes expose existing, tested functionality without
modifying core behavior. All tests pass.
Implement comprehensive conversation management system enabling AI agents
like Claude Code to maintain infinite context and history. Provides semantic
search, smart context retrieval, and automatic artifact linking using Brainy's
existing Triple Intelligence infrastructure.
Core Features:
- ConversationManager API for message storage and retrieval
- MCP protocol integration with 6 tools for Claude Code
- Context ranking using semantic, temporal, and graph scoring
- Neural clustering for theme discovery and deduplication
- Virtual filesystem integration for code artifact linking
- CLI commands for setup and management
Zero new infrastructure required - uses existing Brainy features:
- Storage via brain.add() with NounType.Message
- Relationships via brain.relate() with VerbType.Precedes
- Search via brain.find() with Triple Intelligence
- Clustering via brain.neural()
- Artifacts via brain.vfs()
One-command setup: brainy conversation setup
Version: 3.19.0
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
- Update all internal code, examples, and documentation to use typed methods
- Enhance CLI with new type management commands (types, suggest, validate)
Breaking changes:
- Remove deprecated add() method - use addNoun() with explicit type parameter
- All addNoun() calls now require explicit type as second parameter
This release significantly improves type safety across the entire system while
maintaining backward compatibility for properly typed method calls.
