Evaluate a decision
Run a decision’s published version against an input context.
The publication pointer is resolved once, up front, so the version
and content_sha on the response and the audit event are the ones
that actually executed even if a publish lands mid-request.
For understanding why a result occurred, use the simulate endpoint with a trace instead of enabling traces on production traffic.
Required roles: simulator or above
