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.
A filename whose extension is an Object.prototype key (foo.constructor,
foo.__proto__) resolved to the inherited member through the plain-object index,
so a function reached the read card's lang hint and failed the tool-output JSON
validation, failing an otherwise successful read. Look the extension up as an
own property only. Added rejection tests, converted the zh Note headings to the
all-English sibling convention, and named the parallel-file-reads terminal
golden as the TUI-unchanged evidence in the Testing section (both languages).
readMetaFromMeta narrows the opaque persisted meta boundary, so beyond
shape it now rejects replayed JSON that is well-typed but semantically
invalid: line numbers must be 1-based integers, totalLines a non-negative
integer, and line numbers must strictly increase without exceeding
totalLines. Any violation declines to the generic fallback.
Sync the public ToolResultView contract across the core/tools and
tool-fs READMEs and docs/core-data-structures/tools for the fourth
result-view member and the ReadFileLine vocabulary, and expand the
Agent Note Testing section with the new rejection paths and the snapshot
evidence this PR carries.
A read result now carries card:'read', but render()'s genericContent gate was
card==='generic' only, so the read body kept its text yet lost the dim-Markdown
dimBody treatment the generic card gave it. Admit card:'read' to that gate so
its content fallback takes the same dim path, restoring read's TUI rendering to
what it was before the read card existed. Refresh the parallel-file-reads TUI
golden accordingly and correct the Note's TUI claim on both language sides.
Consume the card:'read' result view (path, numbered lines, totalLines, lang)
the read backend PR added. ReadBlock (ui-primitives) draws a per-line gutter
with each line's own file number, shiki highlighting via a new highlightLines
returning per-line token arrays, a 显示 X / Y 行 window note, a height cap
matching TerminalBlock, and a copy control. read-card-model is the single
resultView derivation; a keyed ReadRow registers under read with the card
resident under its path-link summary. The generic fallback and the details
panel are read-aware. Fixture gains a windowed read turn for the built-boot
snapshot.
The read tool's result carries structured numbered lines, but only the
model-facing envelope text reached the client. Add a card:'read' result view
(ReadResultView) projecting {path, lines, totalLines, lang} through the tool's
output.presentationMeta so presentResult reproduces it on live and replay
paths; the pending call stays a generic read card. A UI without the read
capability falls back to the envelope-stripped content, so the TUI is
unchanged. The web consumer that renders the line-numbered view is a follow-up.
Stats line moves into the InputBar's new footer slot (sharing the card's
width column) and expands to the design's grouped detail row: turns/steps,
LLM and tool wall time, cache hit, and input/output token split, all
derived client-side from the snapshot. The composer stack owns one 8px
rhythm, the seat fades the transcript through a fixed 36px gradient band,
back-to-bottom follows a live --dsh-composer-height, and goal/todo strips
share one 752px tip-fill column.
