What the mounted story proves
  1. 01
    SegmentedControl
    Representative 120×40 terminal state.
  2. 02
    Passive paint
    No keyboard or pointer action is claimed by this representative story.
  3. 03
    Evidence stays explicit
    3 covered · 8 partial · 5 missing axes.

Selection


SegmentedControlState::selected() is the read path. Hosts update selection
through set_selected, which keeps the active cursor synchronized, including
when clearing the selection with None. Keyboard and menu commits use the same
setter.
Ownership boundary
TermRock owns reusable terminal rendering and interaction state. The host owns domain data, policy, persistence, authorization, and side effects.
Evidence status
3 covered, 8 partial, and 5 missing contract axes. Missing evidence is not a behavior claim.
Roving Focus Group
RovingFocusGroup is the exact public behavior owner for navigation terminal UI.
Sidebar
Primary application navigation with sections, hierarchy, badges, status, and rail/drawer collapse. Route state is distinct from keyboard focus.
