 # M-series Fleet Ablation Benchmarks
 
 Same methodology as the 2026-03-09 wave2 doc (`--sweep ablation --resolution 512 1024 2048`,
-checkpoint weights, 3 warmup + 10 bench runs), executed on three machines spanning the
-Apple Silicon range. Contributed from a 3-Mac render-farm setup; happy to run follow-ups.
