"""Returns:
    DIFF_LIMIT: bytes of JSON-encoded patch text one review diff carries, in
        the client that builds it and the hub that takes it.
    DIFF_BODY_LIMIT: bytes of request body the hub reads for an ask or a
        review request; the client sends a larger one without its diff.
    FILE_CAP: files one review diff lists; the client builds no diff of more.
    PATH_LIMIT: characters of a path the hub takes, a diff path included;
        the client builds no diff with a longer one.
    NOTES_LIMIT: characters of review notes the hub takes; the client refuses
        longer notes instead of cutting them.
    WITHHELD: the note of a diff entry that ships without its patch because
        its content may hold a secret.
