 Verify build output, types, e2e tests, and document npm publish + consumer install path in README.
+
+Result 2026-06-24:
+- Build: `npm run build` produces complete `dist/` (JS, `.d.ts`, source maps for all modules).
+- Types: `npm run typecheck` passes under strict TS config.
+- Unit tests: 62 passed. E2E: 4 credential-gated tests skip cleanly; run with `BINECT_USERNAME` / `BINECT_PASSWORD`.
+- Consumer install: validated via `npm pack` + `file:` tarball install; all public exports resolve.
+- Docs: README updated with npm install (consumer), local dev paths, and maintainer publish checklist.
+- Package: added `publishConfig.access: public` for scoped `@binect/js` first publish.
