=== ROUND 4 - PINNED RE-CONFIRMATION (supersedes the TASK's whole-repo scope) ===

Your round-3 report (logs/adversarial/ux-designer-round3.txt) raised exactly 3 findings, all in
the branch-row block of src/core/popup.ts. All 3 are now fixed via the structural remedy your
own report proposed. Current state: Jest 61/61, pytest 132/132, Galata 16/16, eslint 0 errors,
version 0.1.15. Your round-4 job is ONLY:

1. Verify each of your 3 round-3 findings is CLOSED - cite file:line.
2. Inspect ONLY the changed block (popup.ts branch-row block, ~lines 280-347) for any NEW
   regression this change introduced.
3. NO fresh sweep. Nothing previously CLOSED or ruled may be re-examined.

FIX APPLIED (one structural change, net +6 lines, no other file's logic touched):
- The row lost role="button", tabIndex and the keydown listener - it is a plain container again,
  keeping only its click-to-switch mouse listener.
- The label span (popup.ts:280 - contains only the ellipsising text span and the provider/fork
  badge, no interactive children) now hosts role="button", tabIndex=0 and the Enter/Space
  keydown with preventDefault.
- The keydown's first line is `if (deleting) { return; }`, mirroring panel.ts:1371, with a
  comment naming why the jp-mod-busy pointer-events scrim does not block keyboard.
- No CSS change: no focus rule was bound to the row class, so the moved affordance keeps the
  default UA focus ring.

This resolves, by construction: the checkbox and Open/Copy buttons operate natively again (no
ancestor keydown cancels them), the busy lock covers the keyboard route, and role="button" no
longer wraps interactive descendants.

VERDICT: SHIP if all 3 are CLOSED and the changed block carries no new regression; otherwise
DO-NOT-SHIP listing ONLY still-open or new items in that block.
