# v4928.1.5.110 — close guard recognizes completed invoice-send tasks

Fixes a mismatch where the opportunity detail and next-action engine could show
`CLOSE_OPPORTUNITY`, but the operation button was blocked with “Concluir
oportunidade exige evidência de fatura enviada ao cliente”.

The workflow guard now treats completed `SEND_INVOICE` tasks for the same current
invoice as local evidence that the invoice was sent to the customer, matching the
central opportunity-flow evidence builder.

Expected for VIDRALGAR / Maria Cândida style cases:

- invoice linked
- payment confirmed
- WH/OUT done
- completed `SEND_INVOICE` task
- `Concluir oportunidade` button allowed
