//! What an endpoint said about one model it serves.

/// One model an endpoint serves, with what the endpoint said about it.
///
/// **An endpoint's list is more than bare ids.** Everything the
/// provider states beside each id — the window, the ceiling, what the
/// model accepts, what it costs — is what a person chooses a model by.
/// This is that statement, carried to the page that shows the list.
///
/// **Every field is what the upstream said, not what this city
/// concluded.** Absence means the row said nothing; it never means
/// zero, and it is never filled in from the preset table here. The
/// ladder that picks a figure — the person's own entry, then the
/// upstream's statement, then the preset table, then the policy default
/// — runs where the call is made, and a summary that had already
/// climbed it would be a second answer to which figure won.
