" summary

Describes a production system that generates ready to merge PRs to automate refactors and cleanups across Kotlin, Java, Swift, JS, Go and more using a compiler-driven engine plus framework-aware heuristics and a thin layer of specialized AI. Claims merged over 1,800 PRs with deleted over 500,000 lines of code in six months, reports ~90% of PRs require no manual edits, and says the open source Polyglot Piranha approach scales in monorepos.
