Nine findings, one critical. Terminal cases verified in a real terminal first. CRITICAL: cells held the accumulated SGR history, so every state boundary re-emitted the whole chain — output switching color without a full reset emitted O(n^2) characters. Measured: 3200 such cells produced 25 MB, and the reviewer's ~90 KB alternating-color case is well under bash's own output cap. State is now a normalized record (foreground, background, attribute set) with one canonical sequence per boundary, so the emitted text is linear in cells; the 90 KB case parses in 36 ms. That also makes the attribute closers every chalk-based tool writes actually close: `\x1b[1mbold\x1b[22mplain` leaves the following write PLAIN, which a real terminal confirms. Width follows emoji presentation, not the U+2600-U+27BF block: `A✓B` redrawn with `XY` shows `XYB`, so the check every progress line writes is ONE column. Taking the block as wide misaligned exactly the output this card exists for. Writing over either half of a wide pair blanks the other, since a terminal cannot leave one cell of a two-cell glyph standing. `line\n\x1b[0m` does not end in a newline as a string yet its last parsed line holds nothing visible, so the terminator check now reads the parsed lines — it had added a blank row and inflated the collapse count. A line with no cursor movement no longer builds a column buffer at all; only its SGR is folded, so an `ls -R` or a 5k-line log allocates nothing per character. The `.terminalDescription` rule had been inserted into an existing grouped selector, silently giving `.codeBody` description typography and changing its bottom margin from 4px to 0 — a pre-existing surface this PR does not own. Split out, `.codeBody`'s margin restored. Three comments contradicted their code: the fixture's exit-marker line (still claiming recovery from a marker deliberately removed), `bash-sample`'s header (still routing a click to the details panel, and calling the consumer's cap the block's own), and a DetailsPanel comment stacked above the wrong rule. The ui-primitives README documented only the CR/BS half of the replay, so a reader would expect `OK0%` where `100%\r\x1b[KOK` renders `OK`.

Pure React atoms (zero cordis): StateDot, ic_ds_* icons, Button/Pill/Menu/Modal/Input, markdown family (MessageText/MarkdownText/JsonBlock), TerminalBlock. Contract: api-contracts v3 §8.
Markdown rendering
MarkdownText renders GFM from untrusted assistant output through React elements. It omits raw HTML, neutralizes relative and non-HTTP(S)/mailto links, opens HTTP(S) links with safe external-link attributes, and renders image alt text without loading remote resources; MessageText remains the literal-text primitive for user-authored content. Element spacing, tables, links, and inline code use the same --dsw-alias-markdown-* / --dsw-font-markdown-* tokens as deepsuite @deepseek/md. Fenced blocks render through CodeBlock (language banner, copy control, shiki for the registered grammars).
Terminal output
TerminalBlock renders a shell command as a terminal surface: one prompt row per line of the command (the shortened cwd label on the first row only, since the view knows one working directory and a cd moves later lines elsewhere, then that line), the command's output, a status pill for a non-zero exit code or a terminating signal, and a copy control that writes the raw output prop. A run-state StateDot marks the call once, on the first row, out of flow in a gutter the card reserves as its own left padding, so the dot sits inside the card box yet left of the prompt text. It reaches three of StateDot's states — the chase while running, red for the same exit status that renders the pill, green otherwise — so a card states whether its command is still running rather than leaving that to be inferred from the presence of output; it carries one visually hidden text label because StateDot is aria-hidden. One dot regardless of line count is deliberate: the exit status is the whole call's, so a dot per line would claim a per-line outcome the view does not carry. Command text is white-space: pre, so repeated spaces, tabs, and an indented continuation render verbatim while the row stays single-line and ellipsizes. ANSI escape sequences are parsed with the anser runtime dependency into React spans; cursor movements replay into a per-line column buffer before inert controls are stripped, since carriage return and backspace only MOVE the cursor: 100% + CR + OK alone shows OK0%, while the \x1b[K a spinner writes with its redraw erases the tail so 100%\r\x1b[KOK shows OK. Erase-in-line is honored in all three parameter forms, the cursor advances by terminal columns (8-column tab stops, two for emoji and CJK, none for a combining mark), and SGR state is normalized per cell as a terminal stores it, threading across lines and closing at the state the line ended in; basic-16 foreground colors map onto --dsw-* tokens, while 256-palette and truecolor values pass through as literal rgb. Output keeps white-space: pre with horizontal scrolling, so column-aligned output holds its alignment instead of soft-wrapping, and collapses to a head slice plus a tail slice past maxLines (default 16, the TUI transcript's split arithmetic) behind an expand button. Rationale: the web terminal card note.
Model Experience
None, as the package renders pure React atoms in the browser; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- Glyph-level icons are redrawn approximations — the fish logo (and the sparkle held by ui-conversation) come from font glyphs whose vector geometry is not exportable from the local design data; hand-authored recreations stand in until an exact export path exists.
- Pill and Input have no design source — both atoms are self-defined; the sidebar search field and view-tab strip that resemble them are consumer-owned compositions, not these atoms.
- StateDot
Activevariant is a hidden placeholder in the design — not implemented; the four shipped states (done/warning/ongoing/error) are the complete P-I surface. - This package's user-facing copy is inline Chinese, not localized — the atoms are zero-cordis and so cannot reach
ctx.locale;TerminalBlock's exit-code and signal pills, its copy and expand controls, andCodeBlock's copy control are all hardcoded. This matches the repo-wide state the locale package records (only the Settings surface is translated); extracting these into thezh/endictionaries needs a localization channel for zero-cordis atoms and belongs to that repo-wide extraction. TerminalBlockis not a terminal emulator — it renders settled or still-running command output, not an interactive session: SGR color and attributes are honored, and so are the in-line cursor movements a progress line uses — carriage return, backspace, erase-in-line, tab stops and character width. Absolute cursor positioning, screen clearing, and alternate-screen sequences are stripped. Basic-16 magenta and cyan have no token equivalent and stay literal rgb.
