+# RD ideation batch 02 — the mismatched-eye probe
+
+**Purpose:** crack (or rule out) M03's mismatched eyes in diffusion. Batch 01
+proved the base model renders the body/silhouette well and set the 48px
+silhouette floor, but the rounded-shaded idiom collapsed the two eyes to
+symmetry/cyclops. comfy-dev's craft rule: asymmetric eyes survive in FLAT/
+ink idioms. This batch tests that. Output `_ph` ideation; greybox stays
+art-free.
+
+**Canon stakes:** MOE.md — eyes are "the entire performance budget,"
+"mismatched forever" (dim recessed lens + bright bolted-on lamp; the BRIGHT
+one is the warm/patched one). Also MOE.md: Moe's eyes/scars are "authored,
+not procedural." So a null here is not a failure — it confirms eyes are the
+hand-authored layer over a diffusion body. Either outcome is a result.
+
+## Carried rules from batch 01
+
+- **No character LoRAs for M03** — subject prior drags to fantasy battle
+  units regardless of negatives (duelystchar → cyclops). Flat-STYLE LoRAs
+  (flatshading, 1bit) are style priors, should be safe — but watch for it.
+- **A strong subject prior beats a negative.** Foreground wanted features
+  positively rather than relying on the negative to suppress the unwanted.
+- Render 512, downscale nearest-neighbor. comfy-dev owns sampler/steps/CFG
+  and content-checks every render (size + brightness/variance, eyes on the
+  pixels).
+
+## The eye-foregrounded prompt (signature detail FIRST)
+
+**Positive (flatshading variant):**
+> `pixelflat64`, a gentle giant farming robot with **TWO EYES OF DIFFERENT
+> SIZES — one small dim recessed dark lens on one side, one large bright
+> glowing round lamp on the other**, rounded dome head, barrel body, thick
+> column legs on flat round pads, one arm ends in a watering nozzle, warm,
+> huggable, **flat shading, bold outlines**, plain background, front view,
+> pixel art
+
+**Negative:**
+> matching symmetrical eyes, single eye, cyclops, three eyes, extra eyes,
+> humanoid feet, boots, menacing, angular, human face, text, watermark,
+> busy background, arena floor, pedestal
+
+## Batch shape
+
+- **E — flatshading eye probe:** the prompt above, `pixelflat64`, ~5 seeds.
+  Primary test — do two distinct differently-sized eyes render?
+- **F — 1bit eye probe:** swap trigger to `pixel1biticons`, "1-bit, two
+  tone, high contrast" — the flattest idiom, the hardest test. ~3 seeds.
+- **G — frontfacing WITH trigger:** `pixelfurniture64` + the eye-foregrounded
+  prompt (untriggered it already gave the best framing + a spontaneous
+  bolted lamp-arm; does the trigger sharpen or break it?). ~3 seeds.
+- **H — eyed grid ladder:** the best render from E/F/G that actually HAS two
+  eyes, downscaled 64/48/32. Answers what batch 01's ladder could not — does
+  the mismatched-eye read survive downscale, and at what budget.
+
+## Judge
+
+- **Eye test (primary):** two eye objects, visibly DIFFERENT sizes, the
+  bright one reading warmer. Not symmetry, not cyclops, not 3+.
+- Blob-squint still holds (flat idiom must not lose the huggable silhouette).
+- H: at 48px does the asymmetry still read, or does it need 64px? (This
+  sharpens the batch-01 floor: silhouette floor 48, possibly eyes floor 64.)
+
+## Output
+
+Booth E/F/G/H; reply to m03-dev with the URL + your read on whether any
+idiom cracked the eyes + the eyed-ladder floor. If nothing renders two
+distinct eyes, say so plainly — that routes M03's eyes to hand-authoring,
+which is the canon-correct division of labor, not a loss.
