Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR adds simple benchmarks for comparing the `MetaM` and `SymM` simplifiers. The `SymM` simplifier is still working in progress. ### Big picture across benchmarks | Benchmark | MetaM scaling | SymM scaling | Speedup (approx.) | |-------------------------|-------------------|--------------|-------------------| | `trans_chain` | Linear | Linear | ~8–9× | | `congr_arg_explosion` | Super-linear | Linear | ~100× | | `many_rewrites` | Super-linear | Linear | ~10–16× | <img width="598" height="455" alt="image" src="https://github.com/user-attachments/assets/8bd9021b-b9cf-4fc0-aab4-3118d87f7c22" /> <img width="644" height="455" alt="image" src="https://github.com/user-attachments/assets/0234dc11-0be7-441a-83b6-c309d20a2663" /> <img width="611" height="455" alt="image" src="https://github.com/user-attachments/assets/df79d057-25ed-49d9-a8f3-5285e5fc7013" /> |
