 * Two things are being checked. First, that the menu tree matches Python's
 * legacy TUI — the items, their order, and "blank goes back" — since that is
 * the navigation the port exists to reproduce. Second, that the agent-blind
 * rule survives the move to a screen that shows the whole vault: listings
 * carry metadata only, and a stored secret appears solely through the action
 * whose purpose is to produce it.
