+# Convoy: scanner-redesign-a11y-fixes
+
+Closes P1 follow-up from `audit-redesign-scanner-flow-44`.
+
+## Scope
+
+- `components/ScannedCardItem.js` — ownership `role="status"`, labeled selects/buttons
+- `components/CameraScanner.js` — camera control labels, disambiguation focus trap, video label, heading fix
+- `pages/scanner.js` — create-collection modal a11y, bulk toolbar labels, queue list semantics, live count
+- `lib/use-focus-trap.js` (new) — shared modal focus trap
+
+## Acceptance criteria
+
+1. Ownership badge announced by screen readers.
+2. All icon-only and placeholder `<select>` controls have accessible names.
+3. Disambiguation + create-collection modals trap focus and restore on close.
+4. Scanned cards queue uses list semantics; count updates are polite live region.
