New script (scripts/blocoB_pis_cofins_source.py) and evidence artifact (docs/runs/BLOCOB_PIS_COFINS_SOURCE_V1.json): tests whether NCM, CODGRUPO, CFOP, CSOSN or GRUPO_ICMS determine the CST_PIS_COFINS value emitted in NFCE_ITENS, across all 5 installations. Read-only; no Firebird write path exists in this script. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

"""Missão 3 / Bloco B — de onde vem o CST/alíquota de PIS/COFINS emitido, somente leitura.

Testa correlação e determinismo por NCM, CODGRUPO (via C000025), CFOP, CSOSN/CST_ICMS,

GRUPO_ICMS. Não decide regra fiscal - só mede taxa de reprodução.
