Prelude/TypeRep.lean:32

• [nitpick] The variable name constrsA is a remnant of the old Constr.Rep structure and may confuse readers—consider renaming it to paramsA or similar for clarity.

        let paramsDecEq : Decidable (constrsA = constrsB) := @List.hasDecEq _ Rep.decEq constrsA constrsB

Prelude/SomeType.lean:13

• [nitpick] Comparing SomeType by checking only TypeRep.rep may not always reflect the actual BEq semantics of the underlying type; consider leveraging instBEq on values directly or clarifying this design.

  beq a b := a.instTypeRep.rep == b.instTypeRep.rep

Prelude/SomeType.lean:21

• SomeType.cast is a key part of the new type-casting infrastructure but has no accompanying tests; consider adding unit tests for successful and failed casts between known types.

def SomeType.cast {A B : SomeType} (a : A.type) : Option B.type :=

AVM/Class/Label.lean:33

• The falseLogicId case is introduced without explanation; consider adding a comment describing its purpose as a sentinel for non-logic app data.

  | falseLogicId : MemberId lab

AVM/Class/AppData.lean:23

• [nitpick] The AppData equality instance uses === and == interchangeably; for consistency, prefer one operator and document its intended use in this context.

instance AppData.hasBEq {lab : Label} : BEq (Class.AppData lab) where

AVM/Class/Translation.lean:146

• logic' is a central helper with non-trivial control flow; adding a docstring or inline comments explaining each branch and the role of checkMemberLogic would improve readability.

private def logic' (lab : Label) (cls : Class lab) (args : Class.Logic.Args lab) : Bool :=
