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.

// 3.4: a patched leaf that O3 (and O1) inlined: every slot that inlined it is rebuilt at

// both tiers, and a O3 build in flight from the old source is dropped. MAKEPAD_RUN_O3_CALLS=1
|
|
// makes `drive` hot at once; each run sleeps so its O3 build installs before the next edit.
|
|
// v2 also edits the leaf reached through a devirtualised dyn call.
