Classifier before/after (real execution 14404), critical-case table for
the 7 reincident tickets (technician-vs-vendor and contact-vs-waiting
fixes confirmed on real data), Top10 critical inspection, Slack
mechanism confirmation (real test send attempted with explicit user
authorization -- pipeline confirmed working end-to-end up to Slack's own
API, which rejected $vars.SLACK_CHANNEL_TECNICO as invalid), Schedule
Trigger confirmation, test/validation summary, production state
confirmation. Verdict: PRONTO PARA ATIVAÇÃO — BLOQUEADO APENAS POR
ACESSO (Slack channel configuration only, not code or n8n access).
