**Tally**: 4/4 approve, 0 request-changes. No CRITICAL or HIGH findings.

```
VERDICT: GO
```

### Rationale
All four reviewing personas unanimously approve with zero CRITICAL or HIGH findings. The implementation is surgical and well-scoped: 53 lines of production code across 3 files fix all three root-cause bugs (dead CSS selector, dual scroll controller, missing selection hints) with 310 lines of new tests providing strong unit and integration coverage. All 3,074 tests pass with zero regressions. The minor observations raised (approximate unread counter, global Screen overflow, asyncio.sleep in tests) are all explicitly non-blocking and appropriate for v1.

### Unresolved Issues
(None — all findings are LOW severity and explicitly non-blocking)

### Recommendation
Merge as-is. The branch is ready to ship. The non-blocking observations (approximate `_unread_lines` counting, global `overflow: hidden` on Screen) can be revisited if future TUI layouts require different behavior.
