What's New

Fixed WASM embedding engine binary not being included in the npm package (the pkg/ directory's package.json and .gitignore were causing npm to exclude the Candle WASM files)
Added ./embeddings/wasm export subpath for clean ESM imports of the WASM embedding engine

Aggregation Engine

New write-time incremental aggregation engine for analytics and financial reporting.

Features

Aggregation operations: SUM, COUNT, AVG, MIN, MAX with GROUP BY
Time windows: Hour, day, week, month, quarter, year, and custom intervals (ISO 8601)
Write-time incremental: O(1) read performance — running totals maintained on every add/update/delete
Unified API: brain.find({ aggregate: 'name' }) integrates with the existing query system
Materialization: Aggregate results auto-materialized as NounType.Measurement entities, visible in OData, Sheets, SSE, and webhooks
Plugin acceleration: 'aggregation' provider key for native plugin implementations
Persistence: Definitions and state survive restarts; definition changes auto-detected via hash comparison

API

brain.defineAggregate({
  name: 'monthly_spending',
  source: { type: NounType.Event, where: { domain: 'financial' } },
  groupBy: ['category', { field: 'date', window: 'month' }],
  metrics: {
    total: { op: 'sum', field: 'amount' },
    count: { op: 'count' },
    average: { op: 'avg', field: 'amount' }
  }
})

const results = await brain.find({
  aggregate: 'monthly_spending',
  where: { category: 'food' }
})

New Exports

AggregationIndex, AggregateMaterializer, AggregateDefinition, AggregateMetricDef, AggregateSource, AggregateQueryParams, AggregateResult, AggregationOp, TimeWindowGranularity, GroupByDimension, AggregationProvider, MetricState, AggregateGroupState
