 * Not to be confused with the package version, which the index also publishes:
 * that one says which release the content came from, this one says what shape it
 * has. Without separating them there was no way for the registry to change shape
 * without silently breaking whoever was already installed — the CLI would read
 * `files` from an item with a different shape and get it wrong without a word.
 *
 * It goes up when the change breaks a reader: a field removed, a meaning
 * altered, an item reorganized. A new optional field raises nothing.
