Tracks the app that was already in place (capture, treatment, outreach,
WhatsApp integration, server, frontend, tests, docs) so future feature
work can branch and use isolated worktrees.
Detects when a WhatsApp number is shared by multiple leads (e.g. an
accountant's phone reused across client CNPJs) and blocks automatic
and manual outreach to all of them until an operator reviews and
releases the number.
