Phase 2 JS: createWithRvf/saveToRvf/loadFromRvf factories, BrowserWriterLease with IndexedDB heartbeat, rvf-migrate and rvf-rebuild CLI commands, epoch sync helpers. +541 lines to index.ts, new cli-rvf.ts (363 lines). Phase 3: 3 MCP rvlite tools (rvlite_sql, rvlite_cypher, rvlite_sparql), CI wasm-dedup-check workflow, 6 cross-platform compat tests, shared peer dep. Phase 1: 4 RVF smoke integration tests (full lifecycle, cosine, multi-restart, metadata). Node.js CLI smoke test script. 81 new Rust tests passing. ADR-032 checklist fully complete.
