+Touched: none
+
+Continua decomposicao da agenda pra Rail/Clinica. 2 commits cobrindo
+Fase B inteira (read-only + mutations):
+
+Fase B1 (e7e3d1b): agendaBilling.service nasce com
+- computeSeriePrice (puro)
+- generateOccurrenceDates (puro)
+- needsStatusConfirmDialog (puro)
+- loadStatusChangeContext (read-only, 5 deps)
+useMelissaAgenda: 2792L -> 2593L (-199L)
+
+Fase B2 (049dd91): adiciona mutations
+- applyStatusDecisions (~330L — todas as decisoes do dialog)
+- createPackageContract (~140L — upfront/saldo)
+- materializeAndChargePerSession (~90L — per_session)
+useMelissaAgenda: 2593L -> 2042L (-551L)
+
+TOTAL fases A+B1+B2: 3033L -> 2042L (-991L extraidas, ~33% reducao).
+3 pages (Melissa/Rail/Clinica) agora podem reusar mesmo billing
+core. Comportamento Melissa identico — codigo movido linha-a-linha,
+so refactor de signature pra receber deps explicitas em vez de
+closure.
+
+Pendente: Fase C (adapter Rail) + Fase D (adapter Clinica) +
+doc ajuda.
