Line 2 of a session card spelled out its blocked work ("1 uncommitted
file") and its command ("claude"). Both now render as marks: the
breakdown as diff notation, and the command's leading program as its
tool's icon in the web client.
The probe carries the line delta of the tracked changes — staged and
unstaged together, against HEAD — so `git add` never makes the counter
drop. Untracked files stay a file count; counting their lines means
reading every one off disk. A tracked change with no line delta falls
back to `~N` rather than claiming `+0 -0`.
The TUI keeps its command as text: a terminal cannot be assumed to have
a font carrying tool glyphs.
