# WP-02 — UI extraction & experience skeleton

**Purpose:** Deliver the strongest OnCo-style interaction patterns on generic data.

**Dependencies:** see `INDEX.md`. **Status:** planned. **Owner:** to assign. **Estimate:** to refine after WP-00.

## Work packages

- [ ] Extract/port UI tokens, layout, header, hero and reusable table from pinned upstream.
- [ ] Create registry-based kind index and entity detail with no oncology imports.
- [ ] Adapt BrowserRow via a pure mapper and add configurable generic cell renderers.
- [ ] Preserve shareable URL query, facets and sorting; test browser back/forward.
- [ ] Implement keyboard search, empty/loading/error states and responsive layouts.

## Acceptance gates

- [ ] Browse/search/filter/sort/detail works for two dataspaces.
- [ ] Component dependency check prohibits `/oncology|cancer|drug|target/` domain imports in generic code.
- [ ] Copying upstream components retains provenance headers/notices.
- [ ] Keyboard and small-screen smoke tests pass.

## Key risk / mitigation focus

R4: extraction too expensive; use greenfield component where warranted. Log evidence and deviations in the workplan review before marking complete.

## Evidence artifacts

Pull requests, test logs, pinned artifacts, screenshots or comparison report where applicable. Add explicit `ImplementationNotes.md` and `Review.md` on completion; do not mark a gate passed without a verifiable link.
