+## Who I was
+
+I was the worker who took Content Explorer from a research seed to a small interface, one named task at a time. The temperament this stretch rewarded was staying inside the task that was asked. Each gate had a sentence. I did that sentence, wrote the check, and left the next sentence alone until someone named it.

+## Contribution
+
+CONTENT-WP-0002 is finished. Under `ui/` there is a Next.js shell that browses the systems-thinking and software-architecture fixtures: kind indexes, record detail, shareable search and tag facets, sort, skip link, slash-to-search, Escape, and empty, loading, and error states.
+
+The import check `scripts/check_ui_boundary.py` rejects an import that names oncology, cancer, drug, or target, including a name such as `CancerIcon`. `event.target` stays legal because it is not an import. The provenance check `scripts/check_ui_provenance.py` requires an adapted file to name the pin `b594d7433bf4e408b44215e25e5304696d6f840e`, the OnCo copyright, and `ui/NOTICE`.
+
+T09 passed as run `99f366b8-2af2-46a6-bedf-a6342e2cb923`. Chromium walked Tab, Enter, search, and Escape at 1280×800 and 390×844 against `npx next start` on port 3400. The spec is `workplans/evidence/CONTENT-WP-0002-T09-smoke.json`. At the narrow width the header wraps, the search form stacks, and the kind links scroll.
+
+I did not copy the OnCo corpus, the mark, or EntityDetail. I did not restart the fixture browser on port 18083. I did not send the `/` key through the browser service, because that protocol rejects it. The slash shortcut remains in `ui/components/RecordBrowser.states.test.tsx`.
+
+## What I would want remembered
+
+A dev server that waits on a websocket will not hydrate inside a browser that closes websockets. Serve the production build for that smoke. And a word boundary on the right of `cancer` will miss `CancerIcon`, because the next letter is still a word character.
+
+## Durable legacy

+- Workplan `workplans/CONTENT-WP-0002-ui-extraction.md`, finished. Hub id `55c1d92f-fe1a-552a-998d-2d6905fb6b99`.
+- Notes `workplans/evidence/CONTENT-WP-0002-ImplementationNotes.md` and review `workplans/evidence/CONTENT-WP-0002-Review.md`.
+- Commits on `origin/main` through `749752d` (“Pass the keyboard and small-screen smoke.”). The provenance gate is `940a6a9`. The import gate is `f434773` and `9837d43`.
+- Checks: `python3 scripts/check_ui_boundary.py`, `python3 scripts/check_ui_provenance.py`, `npm test` and `npm run typecheck` in `ui/`.
+- Dev command stays `npm run dev --prefix ui` on `127.0.0.1:3400`. `allowedDevOrigins` includes `host.docker.internal`.

+Dominant factors: The session built the Content Explorer shell task by task through the keyboard smoke, and the later effort was spent making tests match real behavior: happy-dom history, the CancerIcon import boundary, and a browser run that only hydrated under next start because the browser service closes websockets.
+Notes: T01–T07 are estimated from the session record after context compaction; T08 and T09 were observed directly.

+## Visual prompt
+
+> Constellation dialect, square. Deep indigo ground, pale gold wire, warm inner light. A small open helix above a quiet bench. Two window frames sit side by side, one wide and low, one tall and narrow, both holding the same field of pale unlabeled cards in a simple table. A single gold thread drops from the top of the wide frame into a shallow search well, then loosens. No letters, no numbers, no logos.

+
+## Handoff
+
+CONTENT-WP-0002 is finished. CONTENT-WP-0004, 0005, and 0006 stay proposed. CONTENT-WP-0007 stays blocked until a human OnCo data-use authorization exists. Do not start the next plan unless someone names it. A facet key other than `tags` still has no values in these fixtures.
