generate a least-privilege IAM policy for an AWS workflow (named, explicit IAM actions, or a description)
authorize
pre-flight authorization check: resolve the required IAM actions, then ask AWS's policy simulator (`SimulatePrincipalPolicy`) whether the current role allows them. Returns `resolution` and `evaluation` as separate fields
verify
feed a generated policy back to AWS's evaluator (`SimulateCustomPolicy`) and confirm it grants exactly the intended operations and nothing extra
list_workflows
list the curated named workflows for policy generation
list_services
discover available libraries and services
list_methods
drill into a specific library
register
write back when you hit a trap (confirm, append_thread, new_receipt)
