We need a new data definition.

fetchReferenceMintingScriptWitness :: UTxO era -> ScriptWitness WitCtxMint era -> UpdatedReferenceScriptWitness

and in the case where the user chooses to supply it

updateReferenceScriptWitness :: PolicyId -> ScriptWitness WitCtxMint era -> UpdatedReferenceScriptWitness

Propagating Maybe PolicyId may work but it results in poor readability. If the user does not supply the policy id we want the ability to query the UTxO to get the reference script witnesses so we can calculate the policy ID.

This would be the short to medium term fix until we can figure out how to encapsulate this in cardano-api.

I agree about the first case with fetchReferenceMintingScriptWitness. I'd do this in a follow-up PR.

What is not clear to me is how to thread in Maybe PolicyId from the CLI argument parser to this place in a clean way. What's your idea about this scenario, when the user provides Maybe PolicyId manually?

I would start with something like: data MintingReferenceScriptWitness era = MintingReferenceScriptWitness PolicyId (ScriptWitness WitCtxMint era)

I'd do this in a follow-up PR.

In this instance I would insist its done in this PR.

No worries, let me push some changes tomorrow to make sure what I am suggesting can actually work.

I've removed my comment as I'm still wrapping my head around the idea and experimenting with it. Feel free to push.
