100%. Also, no need for them to be lambdas.

We need to make a decision: will transactions still be allowed to called directly over the API gateway? If so, we need to support middleware and zod schemas for auth and validation

I think it's be better if allow transactions to be run inline in non workflow handlers. Then wrap it in a command. Maybe add command.transaction

[sam-goodwin]

I agree! I think they should be entirely internal. They don't need to be named, schema'ed or anything. Just a utility.
