M10 (code-complete, verification pending — see OPUS-BUILD-BRIEF-2.md §2):
- Brands with mechanical quality (WONDERSLICE 0.25 vs Crustworthy 0.8 etc.):
quality scales heat-map patchiness and crumb fragility. Bakery sourdough is
loaf-only.
- Slicing minigame: aim thickness, saw with vertical strokes; progress/wobble/
squash; wedge slices brown unevenly in the toaster (the bad cut follows you);
squash arrives as pre-existing damage.
- Bread Knife + THE BEST THING (heavy, soft-scalloped, saw eff 1.65) join the
drawer; on loaf days the drawer trip happens BEFORE toasting ("they are
waiting") and whatever you fish out is what you slice with.
- Day 9 handwritten (the inspector wants a doorstop with parallel faces),
procedural brands/loaf days from day 10, The Cut criterion (band + wedge +
squash, TBT signature bonus), cut line bank.
- Verified so far: day-9 ticket chips, knife-trip drawer with bread_knife AND
the_best_thing present, timer label, typecheck + build. Slicer end-to-end
play, tuning, and couplings assertions are itemised in the brief.
OPUS-BUILD-BRIEF-2.md — the prep bench: generalized ingredients + cutting
(slip, juice, piece-evenness CV), the judged mess field, oranges + ribbed
pyramid juicer (halve evenness caps yield, seeds by juicer tier, the
Juicernaut), the grater (zest/pith line, cheese needs cold, knuckles), onions
(sting that blurs REAL vision, the stop-short-of-the-stem criss-cross dice),
and bruschetta as the capstone (temperature planning, roast tomatoes on the
browning field, topping Clark-Evans, the sog clock vs doorstop slices).
Bakery asset batch partially failed (flux errors + one lost GLB) — regen
instructions with retries are in the brief §8.

The bread slice is the whole game's canvas, so it's built first and properly:
- Field: a 128x128 scalar field with bilinear sample, a mass-conserving brush,
self-levelling relax, and the masked statistics the judge will read.
- Slice: extruded loaf silhouette (domed top), planar-projected UVs so the sim
grid lines up with the bread, per-texel silhouette mask, and four fields
(browning/dryness/spread/damage) packed into one RGBA8 texture per frame.
- Custom shader: browning ramp with blotchy char, crumb/crust/inclusions,
spread wetting + opacity + thickness relief, gloss, gouge exposure, and
flat data views for the judge screen.
- bread.ts / spreads.ts: the archetypes and the rheology the difficulty
curve will live in.
- scripts/gen-assets.sh: reproducible fixed-seed asset generation through
MODELBEAST (flux_local -> bg_remove_local -> hunyuan3d_mlx). All on-device.
Legibility work that mattered: butter rendered invisible at first. Fixes were
a gamma-style wetting darkening (a multiply *brightens* pale crumb), a normal
perturbation taken in UV units rather than raw texel deltas (~30x too small),
and pulling the lighting back under 1.0 so ACES stops desaturating yellow to
cream.
