Editor's note
Recorded from the 2026-08-12 AA snapshot (slug muse-spark-1-2, xhigh, index 56.8). Editorial depth and failure modes still need a desk pass — scores below are ledger-backed, not hands-on claims.
Benchmark placements

Where Muse Spark 1.2 places on each public benchmark source that publishes a row. Rank counts every model with a latest row in the same test — not a universal quality score.
