Keep only groups with another path in the active round. This bounds skewed sampling by paths visited instead of rescanning every singleton for every late-group item.
- 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.
The web_search execute result and searchMetaFromValue each spread the
same {url, title?, snippet?, publishedAt?} projection over a seam source,
which the duplication gate flags as a clone. Extract projectSource, typed
on the seam's WebSearchSource, so both sites carry a byte-identical shape
from one definition.
renderFetchOutput has no external consumer: only formatFetchOutput and
fetchMetaFromValue call it, both through the registry, which deep-freezes
the result value. Exporting it let a hypothetical caller mutate a cached
input or the returned RenderedFetch and desync the card's truncated flag
from the model text. Drop it from the barrel and document that the memo
needs no defensive copy because every caller is internal and read-only.
The base (feat/web-presenter) removed the content field from
WebSearchResultView/WebFetchResultView: the web card carries no content
copy and a capability-less UI falls back to the raw tool/result content
(web-result-card note). The fixture still constructed both web result
views with a content field, failing the e2e build with TS2353. Drop the
content spread and the stale Omit key; the fixture already emits the same
text as the tool/result content the fallback path renders.
Rewrite the Agent Note's stale 'TUI has no web arm' claim to match the
web fallback branch this PR added to transcript.ts. Replace the hardcoded
line-number comment with a symbolic reference, and mark the web arm's
unreachable optional-chain undefined side with a reasoned v8 ignore for
the per-file 100% branch gate.
Route a `web` result card's raw-content fallback through the TUI's dim
Markdown path (render() only recognized `card: 'generic'` as markdown
content, so web fallback rendered as bare undimmed text).
Memoize renderFetchOutput per (result, maxOutputChars) so the registry's
twin output.render / output.presentationMeta calls on the same frozen
result run one HTML->markdown conversion instead of two.
Remove the trailing `</content>`/`</invoke>` protocol residue from both
sides of the web-result-card Agent Note and re-record the pairing.
- 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.
