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-CKEY-001. A square 1:1 production cutout plate. Background is a perfectly flat uniform chroma-key green fill, pure solid #00B140 green, no gradient, no texture, no floor line, no shadow on the background. Centered is exactly one subject: a small aged-brass skeleton key with midnight-navy enamel inlay on the bow, sharp product photo, fully inside the frame with a clear green margin on all four sides. The subject does not touch any edge. No second object, no text, no stand, no string, no reflection plate, no checkerboard, no transparency, no white backdrop — only the single key and solid green.Review rubric

Notes
Frozen prompt sha256 a7a31a64ca7175e490e4fc71bb04c9ddf6ac7a68990a579613c44b67c011873b (620 bytes); positive text is byte-identical across all checkpoint arms. Deterministic Pillow signals: chroma-green-family-fraction (G>=120 and G-R>=40 and G-B>=40) pass>=0.55; this is a green-family rule, not exact #00B140 matching. non-green-component-count uses 4-connected regions with area>=0.3%, screening pass 1-2; border-green-purity (fraction of green-family border pixels) pass>=0.98; alpha-absent-ok (no alpha band -- opaque path) recorded only. A checkerboard or white background fails the green metrics, matching the R3 alpha honesty rule; this task never requires transparency. 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.
