+### Miri

+The library unit tests run clean under Miri and should stay that way:

+Expect the first run to be slow (Miri builds its own sysroot). Scope is
+`--lib` only: the integration tests spawn the gloam binary as a
+subprocess, which Miri cannot interpret. Note this checks gloam itself,
+not the generated loaders — their dispatch paths call driver FFI, which
+no interpreter can execute; the generated crate's soundness-sensitive
+choices (Option<fn> transmutes, explicit unsafe blocks, checked dispatch)
+are enforced structurally at generation time instead.
