Add a Stripe-free provider-hosted MSP mode with local MSP plan workspace limits and portal behavior that hides hosted billing surfaces when no billing record exists.
Make the public MSP signup path create immediate subscription checkout sessions instead of inheriting the individual Cloud trial helper. Preserve the existing individual Cloud trial path, mark checkout billing mode in metadata, and seed MSP checkout-created Stripe account mappings as active.
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.
Use stable control-plane user IDs as hosted tenant organization principals while preserving email as contact metadata and legacy fallback. Cloud handoff sessions now bind to the signed subject instead of email, seeded tenant orgs store owner/member email separately from durable user IDs, and the subsystem contracts pin that boundary.
Revalidate and harden the Pulse multi-tenant GA surface across org ownership transfer, MSP invite lifecycle, tenant state fallback, registry workspace limits, and the embedded Pulse Account portal bundle.
