Release criteria All gates pass; benchmark-readiness review; stakeholder sign-off on structure weighting

Structure Weighting (pending stakeholder review)

Structure Weight Count
dense_ls 20.0% 20,000
contact 15.0% 15,000
via 10.0% 10,000
iso_line 15.0% 15,000
fin 10.0% 10,000
gate 10.0% 10,000
trench 8.0% 8,000
sti 5.0% 5,000
bimaterial 4.0% 4,000
pitch_std 3.0% 3,000

Splits (frozen, deterministic)

Split Count Fraction
Train 70,000 70%
Validation 15,000 15%
Test 15,000 15%

Stratified by structure type; disjoint sample sets (no leakage).
