Implementations have found ways to optimize transform pipelines by collapsing identity transforms, short-circuiting non-observable paths, deferring buffer allocation, or falling back to native code that does not run JavaScript at all. Deno, Bun, and Cloudflare Workers have all successfully implemented "native path" optimizations that can help eliminate much of the overhead, and Vercel's recent fast-webstreams research is working on similar optimizations for Node.js. But the optimizations themselves add significant complexity and still can't fully escape the inherently push-oriented model that TransformStream uses.

Applying these baselines to lf-lean. The lf-lean release includes approximately 215 kLoC of Rocq isomorphism proofs covering the 1,276 translated statements. At the historical median verification rate, this volume of proof would require roughly 2.5 person-years of effort. Combined with the ~3 person-months for translation, we estimate the full verified translation would have taken approximately 2.75 person-years. In contrast, our actual human effort was approximately 15 hours (2 person-days), spent on 6 extreme-difficulty statements that the models could not solve autonomously. This represents a speedup of over 350× on the verification effort and roughly 30× on the translation effort alone.

One final note I would like to share from these meetings with Tony is perhaps the most intriguing of what he said, but also the one he delivered with the greatest outright confidence. In a discussion about the developments of computers in the future - whether we are reaching limits of Moore's Law, whether Quantum Computers will be required to reinvigorate progress, and other rather shallow and obvious hardware talking points raised by me in an effort to spark Tony's interest - he said 'Well, of course, nothing we have even comes close to what the government has access to. They will always be years ahead of what you can imagine'. When pressed on this, in particular whether he believed such technology to be on the scale of solving the large prime factorisation that the world's cryptographic protocols are based on, he was cagey and shrugged enigmatically. One wonders what he had seen, or perhaps he was engaging in a bit of knowing trolling; Tony had a fantastic sense of humour and was certainly capable of leading me down the garden path with irony and satire before I realised a joke was being made.
