Codex round 1, P2, and a real latent bug in the previous commit. Capturing the item OBJECT and reusing it 140ms later keeps a stale snapshot: a rename during the debounce changes the slug, `openItemPane` builds the URL from that slug, and the id-only existence check passes happily on the way to a dead URL. What is captured is now the IDENTITY — `targetId` — and the callback re-resolves the current row from `filteredItems` before opening it. That still follows a row that MOVED, which is the whole point of the fix, and still skips one that was DELETED, while picking up any change to the row itself. Also answering the round's second P2 in the spec rather than in code: the race is probabilistic and cannot be made deterministic without a seam in the page. The asymmetry is what makes that acceptable, and it is now written down — a round that misses the 140ms window still PASSES on a correct build, because the cursor moves, the pane follows and the intended row is where it should be. So missing costs power, not correctness; the failure mode is a false green, never a false red. Three rounds put a false green around 1 in 1700 against a build that loses the keypress 11 times in 12. pane-follow-live-list + pane-controller: 44/44 across both projects.
