Start with relocation. Mike McQuaid landed three related fixes: pull request 23644 rebalances how the bottle checker classifies ELF files as relocatable, fixing false positives from leftover RPATH strings. Pull request 23645 strips node-gyp build debris from npm formulae, since those leftover object files were…
Second theme: build reproducibility and caching. Pull request 23657 splits formula installation into a `fetch` phase, run with network access, followed by an offline `install` phase. That matters because thousands of homebrew-core builds currently download dependencies mid-install with no way to verify or sandbox…
