Request routing for discover/up/down protocol actions.
Factory-driven design: every model in body.create must have a
registered factory. The SDK uses the factory's input_fields both
to validate inputs and to build the discover schema. Ordering for
up and down comes from the create payload's _alias / _ref
graph; there is no SQL introspection.
Summary
Functions
Substitute built-in tokens in field values: {{testRunId}}, {{index}},
{{cycle(a,b,c)}}. Raises Autonoma.Error with code UNRESOLVED_TOKEN for any
other {{token}} that reaches the SDK.
