Ticket: tickets/clens-009-edits-highlight-mismatch.md

All gates are green and the diff is minimal — only tui-formatters.ts production code changed, plus the earlier test file (untouched in this turn).

Summary of the fix

Root cause: both groupFilesByDirectory and groupFilesByAgent recomputed a display position (fileIdx = baseIdx + i via cumulative offsets) after re-sorting/re-grouping the files, then compared that position to highlightIndex — silently assuming display order matched the flat selection order it doesn't.

Fix: resolve the highlighted file by identity instead. In each function, before any sorting/grouping, compute:

const highlightedPath = highlightIndex !== undefined ? files[highlightIndex]?.file_path : undefined;

using the original files array (the flat, selection-order array the caller passed in — the same one getEditsFileList/Enter uses). Then each rendered entry's isHighlighted becomes highlightedPath !== undefined && f.file_path === highlightedPath, which is invariant to how the entry gets re-sorted or bucketed by directory/agent for display.

Since the offset-tracking machinery (groupOffsets, baseIdx, fileIdx, agentGroupOffsets, groupBaseIdx, dirOffsets, dirBaseIdx) existed solely to feed that now-removed position comparison, it was dead code after the fix and was removed to keep lint clean (no orphaned unused vars) — no other behavior changed.
