Three UX bugs from staging testing:
1. Duplicate Pix link in WhatsApp — the tool's formatted_message
embedded the full link + instructions, so the LLM copied it into
its own response on top of the dedicated link message sent by
dispatch_direct_link_message. The tool now returns a short
summary with no URL; dispatch is the single source of the link.
2. "Reserva confirmada!" sent before payment — the scenario prompt
used the word "confirmação" loosely, which the LLM read as the
reservation being closed. Now the prompt forces "pré-reserva /
aguardando pagamento" until the Pix is actually paid, and the
dispatched link message explains that the reservation is only
secured after payment clears.
3. Memory extraction wrote "Reservou Hidromassagem para pernoite
em 22/04/2026" when the customer only received a Pix link and
replied "obrigado". Tightened the extraction prompt so
padrao_comportamental of a reservation requires a literal
payment confirmation — Pix generated alone no longer qualifies.
