Shown indented so it can be read. The hash is taken over the canonical form of the same object — keys sorted by code point, no insignificant whitespace, UTF-8 rather than escaped ASCII, timestamps RFC 3339 in UTC to microseconds, decimals as their plain string form. The check below re-encodes the object canonically before hashing it, which is why an indented display cannot make it pass or fail.
