High-altitude baking adjuster: sugar reduction scaling · case 01
Two cups of sugar lose only one tablespoon at level 1.
ROOT CAUSE
The tablespoon-per-cup reduction is subtracted once instead of per cup.
VERIFIED REPAIR
Multiply sugar cups by (1 - level/16).
Unsuccessful approach: Using level/8 removes two tablespoons per cup per level.
Case contract
Level 0 below 3000 ft, 1 for 3000-4999, 2 for 5000-6999, 3 at 7000+. Baking powder times (1-level/8); sugar times (1-level/16) (1 tbsp per cup per level); liquid times (1+3*level/32) (1.5 tbsp per cup per level); oven +15 F at levels 1-2 and +25 F at level 3. Amounts are fraction strings in and exact str(Fraction) out.
Why this case matters
Cake and quick-bread recipes need leavening, sugar, liquid and temperature changes at elevation.

Verification & scope
A deterministic toy contract stated in full here; it is a bounded teaching model, not an authoritative reference or standards implementation. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
