Two open endpoints: an item lookup by scanned code and the take POST -
the product's first unauthenticated write, held to the decision
record's bar (decrement-only, badge-attributed server-side, bounded,
physically rate-limited; justification in the plugin README). The
/parts-kiosk route is a full-screen no-auth view beside /shopfloor: a
hidden always-focused input consumes keyboard-wedge scans for
whichever step is active, TouchKeypad (net-new 3x4 grid) takes the
quantity, and a success screen resets after a few seconds. Manual
type-in fallbacks cover damaged labels. Kiosk test proves open access,
the over-take guard, the badge policy, and cache==ledger afterward.
