Retire runtime/API/UI monitored-system volume enforcement now that infrastructure monitoring is no longer capped.
Keep only legacy metadata scrubbing and purchase-start compatibility for old max_monitored_systems references.
Rename the remaining preview surface to monitored-system impact and make previews explanatory rather than save-blocking.
Update subsystem contracts and RA7 evidence for the caps-retired invariant.
Remove local upgrade-metrics API registration, settings payload wiring, startup store migration, and backend conversion recorder hooks from the normal product runtime.
Delete the retired conversion/funnel and metering packages from compiled licensing code, and extend diagnostics boundary audits and governance contracts so maintainer commercial analytics cannot return through Settings or diagnostics.
