The base's ReadResultView now requires `offset` (persisted so an empty window
still knows its start). The connection fixture's read sample and read-card.spec's
resultRead helper supply it (the window's first line, 41).
- 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 coverage lane caught a regression in the prior commit: FileMutationRow now
passes the tool's raw path to the injected openFile (which resolves against cwd
in apply.ts), but diff-card.spec still asserted the row pre-resolved. Assert on
the raw path instead. Also fix the built-boot diff assertion to match on the
line body and footer text — the `+ ` prefix is a CSS ::before, absent from
textContent.
Top-level read samples in read-card.spec use the read tool's real file_path
schema key (web_fetch keeps its own path key); the Input-JSON assertion follows.
The LANGS/LANG_ALIASES JSDoc no longer claims the TypeScript grammar embeds
JSX/TSX — shiki's TS grammar tokenizes JSX approximately, an accepted trade to
keep one JS-family boot grammar.
Bring the TUI diff footer onto the same terminator rule and distinct-path
count the Web DiffBlock uses (a trailing newline terminates its line; two
hunks in one file read as 1 file), so the two front ends' `+A -R · N file(s)`
footers agree. Reserve space in the diff path header for the floating copy
button so a long path no longer scrolls under it. Pass the tool's raw path to
the injected openFile (which already resolves against cwd) instead of resolving
twice. Rename the shared block-body CSS class to a card-neutral cardBody so a
terminal-spacing tweak cannot silently move the diff card. Add a same-file
two-hunk TUI unit test and an assembled built-boot assertion that the write
turn renders +1 -0 · 1 file end to end.
Only TypeScript, shell, and JSON grammars load at Web boot; the read card's
wider langFromPath extension set loads through dynamic imports on first use,
so a session that never opens a read card in one of those languages avoids
~1.6 MB of grammar modules and their synchronous init. ReadBlock/CodeBlock
re-render on grammar-load via useSyncExternalStore, picking up highlighting
once the grammar registers. ReadBlock hides the copy control on an empty
window (a successful read of an empty file settles to lines: [] with
card:'read'), matching TerminalBlock so it cannot wipe the clipboard.
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.
