Corrigir este bug saca pai:
O SP_WEIGHTS ta [2, 3, 4, 5, 6, 7, 8, 9] com sum % 11, mas o correto e [9, 8, 7, 6, 5, 4, 3, 2]. Os testes passam porque geram e validam com o mesmo peso errado, mas RGs reais de SP nao batem
Script que valida isto:
WEIGHTS_PR = [2, 3, 4, 5, 6, 7, 8, 9]
WEIGHTS_FIX = [9, 8, 7, 6, 5, 4, 3, 2]
rgs = [
([2,9,4,6,5,3,2,7], 2), # fonte: bosontreinamentos.com.br
([3,9,4,0,6,7,1,4], 9), # fonte: dev.to/shadowlik
]
for digits, dv in rgs:
s = "".join(map(str, digits))
got_pr = sum(d*w for d,w in zip(digits, WEIGHTS_PR)) % 11
got_fix = sum(d*w for d,w in zip(digits, WEIGHTS_FIX)) % 11
print(f"RG {s}-{dv} PR=[2..9]→{got_pr} {'✗' if got_pr!=dv else '✓'} fix=[9..2]→{got_fix} {'✓' if got_fix==dv else '✗'}")Output:
RG 29465327-2 PR=[2..9]→9 ✗ fix=[9..2]→2 ✓
RG 39406714-9 PR=[2..9]→2 ✗ fix=[9..2]→9 ✓
