- Replaced the fixed `CALL_PREVIEW_MAX_LINES` cap in `render-utils.ts` with a dynamic `previewWindowRows()` (terminal rows minus a chrome reserve); `capPreviewLines` now returns lines untouched when expanded and windows them otherwise.
- Applied the cap in every render state for bash and ssh command previews — streaming and final render identically instead of snapping fully open on completion — and included the preview window in bash's render cache key so terminal resizes invalidate it.
- Capped eval cell code previews via the same window; previously cell code was never capped at all, with `ctrl+o` remaining the only way to uncap.
- Added stream-vs-final parity coverage in `bash-sixel-render.test.ts`, `ssh-render.test.ts`, and the new `eval-code-preview.test.ts`, and a changelog entry.
The SSH tool renderer fed the raw command into renderStatusLine's
description, so any newline in the remote command expanded the
single-line tool header — the bordered output block then opened
mid-command and the rest of the SSH cell rendered against a broken
frame.
The renderer now keeps only [host] in the header and renders the
full command (with a dim $ prefix and tab sanitization) as its own
framed section above Output, matching the bash renderer's shape.
renderStatusLine also flattens CR/LF in title, description, meta,
and badge labels so no future caller can accidentally produce a
multiline tool header.
Covered by:
- test/tools/ssh-render.test.ts: multiline command stays out of
the header and every command line is present in the body, for
both renderCall and renderResult.
- test/tui/status-line-newline-guard.test.ts: embedded LF, CRLF,
and lone CR in description/meta are flattened to spaces.
