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.

// G3 / 4.4: struct layout edits (no live values of the type survive between runs).
|
|
// v1: a field is added between two others; make() and sum() are edited to use it. Every fn that
|
|
// uses P's layout (offsets are baked into code) must be recompiled, including outer(), whose
|
|
// text does not change but which embeds P in Outer.
|
|
// v2: only the struct's field order changes (no fn text changes): the derived Debug prints the
|
|
// new order, and every user of the layout is recompiled.
