Internal — owner QA

Funnel walkthrough

Every stage of the funnel in order (PROJECT_CONTRACT §5). Lead-facing surfaces are French; this page is internal tooling and is not linked from any lead-facing screen.

Backend seams (webhook, cron worker, checkout API) don't render — trace them via Supabase: orders, entitlements, external_sync, scheduled_tasks, core_events (correlation_id reconstructs a journey).
