Played end-to-end via the extended harness (t.start/day/pick/slice):
- Day 9 knife trip: bread_knife dragged above the rim, 0.45s dwell commits.
- Clean doorstop (bread knife, 0.05 u/frame): 5 strokes, wedge 0, squash 0.
STROKE_GAIN 0.16 -> 0.10 to hit the 4-6 deliberate-stroke feel.
- The Best Thing: 3 strokes, and the same wobble input that wedges the bread
knife to 0.299 only reaches 0.044 — nearly wobble-proof, as specced.
- Coupling: wobbled cut toasts at browning stdev 0.088 vs 0.071 clean, same
mean — 'a bit wedged' band (>0.18) confirmed in the Cut criterion.
- Slam cut (0.4 u/frame): squash 1.0, arrives pre-damaged (damage 0.02 pre-toast).
- Soup spoon siege: 17 strokes / 166 frames, miserable but possible.
- Brands: quality now drives heat-noise amp (0.12+0.42*(1-q)) AND blotch
frequency (3+3*(1-q)); WONDERSLICE visibly patchier than Crustworthy at 10s.
- Slicer visuals: cut seam deepens with progress; freed slice tips off the
loaf and lands crumb-up (doneTimer 0.7 -> 1.05 for the fall).
- gen-assets.sh: retry-once per stage (rsync flakes), bakery seeds bumped,
prep-bench cast queued ($1 prep).

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.

Playable: pick a bread, set the dial, drop the lever, watch it brown, pop it
onto the plate. No timer readout — you go by smell.
- toasting.ts: heat map from real toaster behaviour (element stripes, cool top
edge where the slice stands proud of the slot, edge falloff, per-run noise
bias). Moisture must boil off before the crust browns at full rate, so
sourdough stalls then catches up; sugar browns and burns early.
Rate is measured against the heat map's actual ~0.77 mean, not guessed:
power 6 -> golden 0.511 at 10s, verified in-browser.
- Props on a real scale (1 unit ~ 11cm, one slice wide) — the toaster is
meant to dwarf the bread.
- The pop solves a genuine ballistic arc from slot to plate.
Three bugs found by driving it rather than trusting the compile:
- valueNoise2D read one past its grid at x=w-1, so heatBias was NaN along an
edge, which poisoned mean browning to NaN — i.e. every judge score would
have been NaN. Clamped.
- erode() clamped at the field border, so border texels could never erode out
of the mask and kept those NaNs in scope. Off-grid now counts as outside.
- Timer.connect(document) zeroes dt whenever document.hidden is true, which
froze the sim solid in an embedded browser. Dropped; rAF already pauses for
hidden tabs. App.step(dt) is now exposed so the game can be driven
deterministically for verification.
Also: screen shake was mutating the camera permanently instead of offsetting
it per-render, and the plate's lathe profile touched the axis (degenerate
triangles -> starburst normals) — rebuilt from primitives.
