CALL NUMBER: resilience_and_reliability_engineering_patterns.blue_green_deployment DEFINITION: parallel environments with instant traffic switch; enables instant rollback on failure

Invoke this skill to understand blue_green_deployment down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.
