Captain's log for #148. PLN heard the album's cuts were wrong within seconds of
a private SoundCloud upload; the bug went four layers deep, ending at a
provenance note that borrowed a true r>=0.99 from an entirely different
measurement.

Two learnings worth the write-up. First: a verifier that passes the case you
built it for is not yet a verifier — mine passed WAP and Drums, the two tracks
he had actually complained about. Second, and his line not mine: the text editor
knew every boundary exactly and never wrote it down, so we spent an afternoon
reconstructing from audio what a log line would have given for free.
