Muse Spark 1.2 is already resellable — and the 77.0 going around is LuminaBench, an aggregate rather than a leaderboard runpost

CORRECTION (2026-08-06). The version of this post published yesterday said the 77.0 had no harness named. That was wrong, and the mistake was ours: a companion post three seconds earlier named the benchmark and linked it. We read one post of a pair and drew a conclusion from the half we had.
