Review comment:
Rather than asserting the constant is there, the AOT tests should try to
use the constant when generating the workspace and stop using the JSON variant
- so we can test whether it works E2E.

We should pass this as an integer rather than a string

Review comment:
Can we check the brief as well to ensure we don't break it in future? (I
have done this by accident when refactoring it)
