- webCardModel returns null for an unknown web `kind` (wire from a newer host)
instead of drawing it as a malformed fetch, matching the unknown-`card` and
terminal-model wire-boundary default.
- Fixture WEB_SEARCH_RESULT/WEB_FETCH_RESULT and the source type derive from the
contract's ToolResultView via Extract, so a new contract field fails at the
type level rather than drifting silently.
- built-boot smoke asserts the web_search/web_fetch turns render their keyed
WebRow cards, giving the registration and wire projection an assembled check.
- DetailsPanel comment no longer claims the card omits content for search.
- ui-primitives README inline-Chinese limitation now lists WebBlock's controls.
