Inputs

Input	Type	Validator	Description
Governance	Script	governance-validator	Spent to verify teacher authorization
Access Token	Wallet	-	Teacher's u-token
Wallet UTxOs	Wallet	-	ADA for fees/deposits

Outputs

Output	Validator	Value	Description
Governance	governance-validator	lovelace + token	Returned unchanged
Module UTxO	module-validator	~1.59 ADA + module token	New module (per mint)
User Wallet	wallet	u-token + change	Access token returned

Minting Operations

Policy	Token Name	Quantity	Description
module-policy	{slt_hash}	+1	Module token (name = hash of SLT list)

Module Token Naming

The module token name is a 32-byte hash computed from the SLT strings:

Input:  ["I can mint an access token.", "I can complete an assignment."]
Output: 8dcbe1b925d87e6c547bbd8071c23a712db4c32751454b0948f8c846e9246b5c

The redeemer contains the full SLT text - the hash is computed on-chain.

Module Datum

Constructor 0:

Reference Inputs

UTxO	Description
