signed-bundles

100,000-product hybrid vector + BM25 search and recommendations running entirely inside the shopper's browser tab (SQLite WASM + OPFS + 2-bit TurboQuant, zero per-query server).

Package SQLite databases and vector/BM25 indexes as Ed25519-signed, content-addressed bundles with FastCDC delta sync for offline and browser execution.

Beta. Funder outcome reports where every reported figure is a receipt: the exact query, the rows it drew from, a content hash of that slice, and a timestamp. Deterministic, offline, and fail-closed. Export is refused if a number in the narrative, or in a chart or comparison claim, cannot be traced to the data that produced it.

Browser Web Worker runtime (@gainratio/browser) that verifies Ed25519-signed bundles and runs SQLite WASM + OPFS FTS5 BM25 + quantized vector search offline.
