Pull Request Overview

This PR updates the conda-forge tick migration logic to make create_migration_yaml_creator v1‐compatible by adopting a new Pydantic‐style schema extraction function.

• Replaces multiple instances of get_keys_default with get_recipe_schema_version in utility functions
• Adds tests for get_recipe_schema_version and adjusts migration creator logic to use a consistent feedstock naming approach
• Refactors the run_exports processing in migrators and updates related test fixtures

• [nitpick] Consider adding parentheses to clarify the conditional expression for better readability, e.g., assert get_recipe_schema_version(attrs) == (version if version is not None else 0).

assert get_recipe_schema_version(attrs) == version if version is not None else 0

Thanks a bunch for this PR and the tests!

This one is going to conflict pretty badly with a big refactor I am working on in #3897. That refactor is nearly ready to merge, but not quite there yet.

What do we think is the best way to proceed?

[ytausch]

Where exactly do you think the conflict happens? After having a brief look at your PR, it looks to me that you currently have only some minor changes to the debug output of create_migration_yaml_creator and to the signature of the MigrationYamlCreator constructor. Besides that, you didn't modify create_migration_yaml_creator.

The test file is the main spot I think?

I don't think this is too much of an issue. Either branch should be able to merge and resolve the problems if merged last. The test resources here are mostly just a copy of the current cf-graph files.
