Module v15 

Constants

PLATFORM_V15

Introduced as the activation gate for the consensus changes of the 4.3 line. Functionally identical to v14 at introduction: the same component version structs, no behavior change. Each change that needs this gate lands in its own follow-up and bumps the component table it consumes here; keeping v15 == v14 until then lets mixed-version validators agree.
