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.

Rust
// `use widgets::Rect` imports both namespaces of `Rect`: the value (a fn, from one glob of
|
|
// `widgets`) and the type (a struct, from another glob, reached through an import chain that
|
|
// resolves later than the value). rustc binds both; the import must not settle for the
|
|
// namespace it found first while a glob it looks through is still open.
