OPS.19:10 - Rationale

Simultaneous operating Work creates a domain decision beyond generic several-structure synthesis. C.32.MWA can produce the architecture evidence, but it does not select the operating reconfiguration, apply Operations commitments and protected conditions, or return the service, cash, quality, recovery, and authority consequences.

The Method also remains distinct from OPS.11. Interacting-structure coordination can settle one concrete coupling, while OPS.19 opens when several otherwise valid operating results conflict across subjects, scopes, or horizons and must be reconciled in one authorized Operations decision.

The short result keeps the burden bounded. Coherence comes from explicit relations and qualified consequences, not from a master diagram, universal scale stack, branded school, or exhaustive model.
