Conversation
…eline Core Changes: - New dom-snapshot.ts: 13-layer LLM-optimized DOM pruning engine - Tag filtering, SVG collapse, ad/noise detection - CSS visibility, viewport threshold, paint-order occlusion - Shadow DOM traversal, same-origin iframe extraction - BBox parent-child dedup, attribute whitelist + synthetic attrs - Table → markdown serialization - Incremental diff (mark new elements with *) - data-opencli-ref annotation for precise click/type targeting - Hidden interactive element hints (scroll-to-reveal) New APIs: - IPage.scrollTo(ref) — scroll to snapshot-identified elements - IPage.getFormState() — extract all form fields as structured JSON - scrollToRefJs(), getFormStateJs() — standalone JS generators Integration: - Page (daemon) + CDPPage (direct CDP): use new engine as primary - dom-helpers click/type: 4-layer fallback (data-opencli-ref → data-ref → CSS → index) - Exports from browser/index.ts barrel Testing: - 21 new tests for dom-snapshot engine - All 283 tests pass (29 files, 1.07s) - Split test scripts: npm test (unit only), npm run test:all (full)
