Size is measured by `size-limit` which checks gzipped size of the `{ nanoquery }` import. - -## Metrics -- **Primary**: `size_bytes` (bytes, lower is better) — gzipped bundle size reported by size-limit -- **Secondary**: `raw_bytes` — uncompressed JS size of `dist/nanoquery.js` - -## How to Run -`./autoresearch.sh` — builds, measures size, outputs `METRIC size_bytes=N` and `METRIC raw_bytes=N`. - -## Files in Scope -- `lib/factory.ts` — Core implementation (~663 lines).
