●MidNiche Gem
Solid Lean tutorial, but implementing insertion sort proofs is a standard exercise in the field.
Strengths
- •Clear progression from basic relations to full algorithm verification.
- •Executable code snippets make the abstract type theory concepts concrete.
- •Omits permutation proof honestly to keep the post length manageable.
Weaknesses
- •Insertion sort verification is a 'Hello World' level problem in formal methods.
- •No novel library, tool, or technique introduced beyond standard Lean pedagogy.
