policyXPub is needed in constructTransaction in two cases:

  • tx contains minting/burning action
  • tx deals with reference scripting and has reference script template nonempty

instead of using policyXPub we use policyXPubM throught the function and only deconstruct it when checking those two cases. ErrReadPolicyPublicKeyAbsen is used for the those two valid situations when policy xpub is missing.

🤔 Having to resort to an approach with fromJust seems unfortunate...
