Scalability

Initial implementation targets correctness over horizontal scale optimization.

Current characteristics:

• one KickRequest per target Deployment;
• request coalescing prevents duplicate restarts for the same target;
• gate and freshness checks are recomputed from live state before action.

Operational guidance:

• monitor kick_controller_errors_total and queue behavior;
• scale controller resources before increasing managed namespace count;
• validate provider API rate behavior in your environment.
