file search: / on a file pane types a pattern into the tag tail (the existing modal one-line editor — persistent, no popup); Enter runs grep -nH '<pat>' '<path>' in a shell in the file's dir via the existing exec path (ttyForDir + write effects), so results are ordinary persistent terminal text. n/N walk the result rows of that pane (paneCursorLines already blanks prompt/echo rows via the OSC 133 semantic marks), select the row with the modal line selection, and hand path:NNN: to the existing look (actOnSelection right) which scrolls the file pane there. Esc cancels and restores the tag. State: four Pane fields (search_edit/search_at/search_pane/search_row) — no results mirror, no highlight engine. New snap script fsearch.snap + golden; all 18 frozen goldens stay green (19/19).
