Summary#
Opt-in feature rollout across decoupled components
Problem#
Core, launcher, and frontend often need a new capability at different times; shipping it as always-on creates accidental behavior changes and coordination risk.
Solution#
Introduce a registry-backed feature flag with a safe default off, make it discoverable via existing introspection/listing paths, and pass it through the existing capability handshake so downstream components can opt in independently.
Failure Modes#
- Defaulting the flag on and silently changing behavior for existing users
- Adding a flag that is not exposed through diagnostics or listing commands
- Coupling the rollout to one client so partial deployments break
