no Gateway bypasses on the sensitive path
policy / transform / receipt chain preserved end-to-end
partner_fit_inputs consumption
meeting_need_vectors consumption
passport.partner_fit consumption
runtime and health integrated into Cortex
/tmp/FMIE.log breadcrumbs surfaced through health status and observability
document regions in production
identity vectors and matcher usage

P2 items remain deferred by design:

live sessions
cross-camera continuity
