The JIT that runs makepad apps from source: lexer, front end, type checker, lazy borrow checker (Gandalf; `--check-first` opts in), codegen, session and warm/cold caches keyed by compiler stamp, provided crates bound late, startup images, live patching. User-facing name is `makepad run` (binary `makepad`, MAKEPAD_RUN_* env, ~/.makepad-run); libs/relax stays the internal library name. `makepad check` reports rustc-style diagnostics with rustc error codes and checks a whole workspace (`--workspace`). Runs on macOS, Linux, Windows and Android. makepad-remote: one tool schema for apps and the WM (app/1): grabs, captures, traces, frame profiles and tweaks.

// make_mut / From<Box<T>> on struct-tailed DSTs (CStr, OsStr, Path): their CloneToUninit is a byte

// copy of size_of_val(self). Under Relax this needs size_of_val of a struct whose last field is
|
|
// unsized (CStr { inner: [c_char] }), which Relax currently reports as 0 (frontend item, coord.md

// 2026-10-04 std-core): this file is the repro and differs from rustc until that is fixed.
