Bun standalone executables store their JavaScript code by appending it after the ELF sections, marked with "---- Bun! ----". The standard Nix build process was corrupting this: - autoPatchelfHook rewrites the entire ELF, losing appended data - strip removes data after ELF sections - patchelf shrink-rpath also rewrites the ELF Fix by: - Using dontStrip and dontPatchELF to skip automatic fixup - Manually running patchelf --set-interpreter which modifies in-place without rewriting the entire file structure This restores the binary from 99MB (bare bun runtime) to 220MB (full claude-code application). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> Executed-By: mayor Role: mayor
