Round-2 test-only locks (behaviors already at parity): - focus (Ink test/focus.tsx): activeId resets to null on Esc, updates on programmatic focus(id), resets on unmount of the focused item, is null initially then Tab lands on first; Esc does NOT clear focus while focus management is disabled; focus(id) targets a deactivated (isActive=false) item (membership-only, ignoring isActive). - screen-reader (Ink test/screen-reader.tsx) via the live renderToString component path: aria-label-only Text/Box, display:none subtree skipped, column>row space-join, single-box aria-states (checked/selected/multiselectable + multi-state ', '-join), role-only button, Transform accessibilityLabel replaces children. Codex-reviewed GENUINE (expected strings match vue output + Ink intent). Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
