From b3ab4bb19a0e6e5df374b9b3edade04c4943c5fb Mon Sep 17 00:00:00 2001 From: "russell@unturf.com" Date: Tue, 14 Apr 2026 13:31:05 -0400 Subject: [PATCH] Add proof friction benchmark, update README MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Benchmark: Python 0.04s, uncommonlisp 59s, Lean 1.5s — for the same claim. The formal proof is 40x faster than brute-force search with mathematical certainty instead of floating-point tolerance. This is MOAD-0001 at the proof layer: O(N²) search friction where O(1) algebraic reasoning suffices. Proof assistants are the hash set to numerical analysis's nested loop. --- README.md | 39 ++++++++++++++++++++++++++++-- proof/benchmark_results.md | 49 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 86 insertions(+), 2 deletions(-) create mode 100644 proof/benchmark_results.md diff --git a/README.md b/README.md index 37481a6..5724819 100644 --- a/README.md +++ b/README.md @@ -133,13 +133,48 @@ make bench # compare interpreter vs bytecode vs CPython make lint # syntax check all Python files ``` +## Portal — machine state migration + +Serialize a running VM mid-computation, transfer to another machine, resume: + +```bash +# Machine A: start a long computation with checkpoints +python3 uncommonlisp.py --fast examples/portal-prime.lsp +# saves prime-state.portal at checkpoint + +# Machine B: resume from checkpoint +python3 uncommonlisp.py --portal-resume prime-state.portal +# continues from exact instruction +``` + +The portal captures the full env chain, compiled procedures, continuations, +and frame stack as JSON. 16KB for a primality test in progress. + +## EML universality proof + +The `proof/` directory contains a formal verification that `eml(x,y) = exp(x) - ln(y)` +with constant 1 generates all elementary functions (arXiv:2603.21852v2). + +Three approaches, benchmarked: + +| Approach | Time | Guarantee | +|----------|------|-----------| +| Python (numerical) | 0.04s | 1e-10 tolerance | +| uncommonlisp (numerical) | 59s | 1e-10 tolerance | +| Lean 4 (formal proof) | 1.5s | kernel-verified | + +The formal proof is 40x faster than brute-force search with infinitely stronger +guarantees.
