Automation Shape Routing

Choose the smallest execution shape that preserves the required evidence and control. This skill routes; it does not build or start a substrate.

Ordered routing works because each rung is strictly cheaper to operate than the next: if the smallest shape truly preserves the evidence and control the task needs, every larger shape can only add coordination cost, never correctness.

Named failure mode — substrate romance: routing to persistent workers because the topology is interesting, not because any deciding axis demands it.

Anti-pattern: starting the chosen substrate as part of routing "to save a step". Corrective: return the one-line verdict and let the owner start under its own authority.
