/**
 * Where the panel says a value came from.
 *
 * The green dot reads "you said this". It was written for every value these
 * tools touched, including ones the model chose on its own: a browser run
 * showed a 20.00 daily budget and US targeting marked as the user's when
 * neither had been asked. Someone approving that summary is approving a budget
 * they never set, and the publish gate only refuses outright guesses, so
 * nothing downstream catches it.
 *
 * What separates the two is whether the question was ever on screen, which the
 * workspace already records.
