Menu
Segmented control
Accordion
A control with no evidence attached. It is recorded as an
unknown rather than assumed compliant — the distinction is the whole point of the audit trail.
The engagement lead, and only before the scope is countersigned.
Inside the client boundary. It never leaves.
Open state lives in aria-expanded and the chevron rotates from it, so
the visual and the announcement cannot disagree. Keyboard highlight in the menu uses the same
treatment as hover — a menu driven by arrow keys should not feel like a different control from one
driven by a mouse.
