Parth Shastri	8223a96bf5	fix: correct universe used in `below`/`brecOn` for non-reflexive inductive types (#8937 ) This PR changes the output universe of the generated `below` implementation for non-reflexive inductive types to match the implementation for reflexive inductive types in #7639. This fixes the `below`/`brecOn` implementations for certain nested inductive types, as reported in https://leanprover.zulipchat.com/#narrow/channel/270676-lean4/topic/Universes/near/525030149.	2025-06-23 09:42:31 +00:00
Parth Shastri	5d50433e6a	fix: allow arbitrary sorts in structural recursion over reflexive inductive types (#7639 ) This PR changes the generated `below` and `brecOn` implementations for reflexive inductive types to support motives in `Sort u` rather than `Type u`. Closes #7638	2025-06-13 21:51:09 +00:00
Joachim Breitner	5ad5c2cf04	fix: universe level in .below and .brecOn construction (#4651 ) I made a mistake in #4517, fixed here, so about time to add a test. I wonder if this generic level optimization should be moved into `mkLevelMax'`, but not today. fixes #4650	2024-07-04 18:19:43 +00:00

fix: correct universe used in below/brecOn for non-reflexive inductive types (#8937 )

This PR changes the output universe of the generated `below`
implementation for non-reflexive inductive types to match the
implementation for reflexive inductive types in #7639.

This fixes the `below`/`brecOn` implementations for certain nested
inductive types, as reported in

fix: universe level in .below and .brecOn construction (#4651 )

I made a mistake in #4517, fixed here, so about time to add a test.

I wonder if this generic level optimization should be moved into
`mkLevelMax'`, but not today.

fixes #4650
