about

nx_dom_query.nx -- bits-up DOM query primitives for the Nishi test harness arc. Subset of full nishi-browser (see NISHI_BROWSER_ROADMAP.md); scoped specifically to what the .mjs Playwright harnesses need so they can be retired per [[feedback-test-harness-is-the-last-non-bits-up-surface]]. Built on top of nx_html_tokenizer.nx (HtmlCursor + nx_html_next_token). Four MVP queries the test harness needs: nx_dom_find_class -- first START_TAG whose class attr contains a word nx_dom_find_attr_eq -- first START_TAG with attr="value" (exact) nx_dom_count_tag -- count START_TAGs with given tag name nx_dom_count_class -- count START_TAGs whose class attr contains word All scan the HTML byte buffer directly via the existing tokenizer. No allocations beyond the caller's buffer; offsets returned into the source.
