Hot path / Cold path: the execution split
A broadcast deployment lives or dies on the split between what happens live and what happens in preparation. Most vendors collapse this; Machina makes it the architecture.
The hot path is the match window. Canonical event resolution in under 100ms. Policy-gated action with full trace. Source-cited output, reversible. Operator approval stays in the loop.
- Hot path (live): event resolution <100ms, policy-gated actions, traced output, operator in loop
- Cold path (pre/post): Run of Show ready 7 days out, multi-language batch, social calendar queued, rights and provenance baked in
