…(RT 2026) Add PAULISTANA_BINDINGS registry mapping nfse_version to the nfselib bindings module and header Versao: - v02: schema v01 (legacy, taxable events until 2025-12-31), Versao=1 - v03: schema v02 (Reforma Tributaria IBS/CBS), Versao=2 serialize_nfse_paulistana(nfse_version=...) keeps v02 as default, so current behavior is unchanged. In the v03 bindings tpAssinatura is xs:base64Binary (generateDS export b64encodes and requires bytes), so the RPS signature string is ascii-encoded before assignment. KNOWN GAP (follow-up): in schema v02 the service amount fields moved to new groups; ValorTotalServicos/ValorTotalDeducoes (Cabecalho) and ValorServicos (RPS) are silently swallowed by the generateDS constructor kwargs and are absent from the v03 output. Mapping the amounts (and the new IBS/CBS groups) is required before using v03 for real emission.

Contexto
Preparação para a emissão de NFS-e paulistana com os schemas da Reforma Tributária 2026 (IBS/CBS). Empilhado sobre #732 (fix dos testes) — mergear aquele primeiro.
Na
nfselib.paulistana, o pacotev03contém as bindings do schema v02 da prefeitura (zipschemas-reformatributaria-v02-4, Manual WS v3.3.7).O que muda
PAULISTANA_BINDINGSmapeandonfse_version→ módulo de bindings +Versaodo cabeçalho (v02→1,v03→2).serialize_nfse_paulistana(nfse_version="v02")— default mantém o comportamento atual (schema legado). Com `"v03"", gera o lote no schema novo.tpAssinaturavirouxs:base64Binary(o export do generateDS aplica b64encode e exige bytes) → a string de 86 posições do RPS é codificada em ascii antes da atribuição. Mesmo ponto do bug latente no [IMP] paulistana: reforma tributaria erpbrasil/erpbrasil.edoc#94, que perdeu o.encode("ascii").test_serialize_nfse_paulistana_v03validando módulo de binding,Versao=2, assinatura em bytes e export do XML.No schema v02 os campos de valores mudaram de estrutura:
ValorTotalServicos/ValorTotalDeducoes(Cabecalho) eValorServicos(RPS) não são mais aceitos com esses nomes — o construtor do generateDS engole kwargs desconhecidos silenciosamente e o XML sai sem os valores de serviço. O mapeamento dos valores e dos grupos novos (IBS/CBS,tpValores,RetencaoPisCofins/NT-007) fica para PR subsequente.Testes
