Protocol
Round 4S SwarmUI throughput cell: this frozen prompt is planned across five shared open-weight checkpoints at 1024x1024 with three unseeded repetitions each. One hosted MiniMax calibration arm has run; the five-checkpoint SwarmUI matrix remains blocked and unexecuted.
Frozen prompt template
CONTROL PROMPT R4S-MAT-001. A wide 16:9 museum catalog still-life on a seamless pure white cyclorama. Exactly four separate objects rest on the white surface, spaced apart, not touching each other, not touching any image edge, and nothing else is in the frame: (1) LEFT a brushed aged-brass metal sphere with visible circular brushing marks and warm yellow-brass color; (2) LEFT-CENTER a transparent frosted glass cube with soft internal refraction and cool gray-white glass; (3) RIGHT-CENTER a folded midnight-navy velvet cloth showing deep soft fabric pile; (4) RIGHT a polished black obsidian pyramid with sharp specular highlight. Hard studio softbox lighting from upper left, soft contact shadows only, photoreal product photography, no text, no labels, no logos, no extra objects, no hands, no reflections of a room, no colored backdrop.Review rubric

Notes
Frozen prompt sha256 9d165554dd4072f387d29f18b2279bc535f4da0edf30a7016290fcdb2b859759 (843 bytes); positive text is byte-identical across all checkpoint arms. Deterministic Pillow signals (screening, not quality): bg-near-white-fraction (min(RGB)>=240) pass>=0.30; border-near-white (border mean min(RGB)>=220) pass true. nonwhite-blob-count uses a 4-connected min(RGB)<230 mask with area>=0.5% but is diagnostic only because frosted glass can disappear and contact shadows can bridge objects. Non-claims: N=3 unseeded reps per cell are a launch/screening signal, not a leaderboard; deterministic pixel metrics are objective facts, not quality judgements; rubric-* items require a separate vision review; no OCR or topology facts are produced this round. Failed, moderated, and discarded runs remain in the public data when legally releasable.
