models: output: Make EnvironmentVariable a frozen model#1651
Merged
Conversation
EnvironmentVariable instances are never mutated after construction. resolve_value() is a pure function returning a new string. Making the model frozen enforces this invariant and enables hashing, which allows using EnvironmentVariable in sets and as dict keys.

Code Review
This pull request updates the EnvironmentVariable Pydantic model in hermeto/core/models/output.py to be frozen (frozen=True), making its instances immutable. There are no review comments, and I have no additional feedback to provide.
