Archive entry for the set-judge build. The entry worth reading later is not the
tool but its first run: it was built to collect go/no-go verdicts and what it
actually established is that the OPAL-26 masters are fine and every middle CUT
is wrong — nine boundaries ear-verified in one sitting, with errors of 3 to 21
seconds that two automated detectors had certified clean.

Also records the four silent traps the build walked into (heads are intros; a
green build with dead playback; three verification probes that tested nothing;
two latent bugs surfaced by reusing existing components).
