Entity Resolver for Node.js and Browser

A stateless, pure-computation entity resolver engine with WASM acceleration. Built for TypeScript first, designed for any JavaScript runtime.

Entity Resolver is pure computation. f(records) → {clusters, matchPairs, scores}. No side effects. No I/O. No internal mutable state. Runs anywhere JavaScript runs.

// Pure computation — zero I/O, runs anywhere
import { dedupe } from '@agentix-e/entity-resolver-core';

const records = [
  { name: 'John Smith',  dob: '1990-01-15', city: 'New York' },
  { name: 'Jon Smyth',   dob: '1990-01-15', city: 'NYC' },
  { name: 'Jane Doe',    dob: '1985-06-20', city: 'Los Angeles' },
];

const result = await dedupe(records);
// result.clusters:  { clusterId → recordIds }
// result.scores:    pairwise match probabilities
// result.diagnostics: waterfall data, histograms, m/u charts

// Node.js — with file I/O and SQLite persistence
import { dedupeFromFile } from '@agentix-e/entity-resolver-node';

const result = await dedupeFromFile('customers.csv', {
  entityStore: 'sqlite:mydb.sqlite',
  autoconfigure: true,
});

See ARCHITECTURE.md for the full architecture document, including:

• Stateless core design with DI interface contracts
• Fellegi-Sunter probabilistic model (EM algorithm)
• 5 blocking strategies + 19 scorers + 3 clustering algorithms
• 3-layer framework-agnostic visualization system
• Incremental update engine
• WASM acceleration via Rust → WASM (auto-fallback to pure JS)
