- built-boot smoke asserts [data-variant=web][data-tool=web_search/fetch]
(the keyed WebRow) instead of [data-web] (which WebBlock draws even on the
GenericToolCard fallback, so a silent keyed-registration failure passed).
- WebBlock renders an explicit empty-state note when a search returns no
answer and no sources, instead of a blank <ol>; the chat row does not
surface the raw result content, so the backend's 'No results found.' was
otherwise invisible.
- README (ui-conversation, ui-primitives) and the frontend Agent Note record
the unknown-web-kind null arm, the details-panel flattened body, and the
empty-search copy; pairings re-recorded.
