   compiler process, so it is process-wide in practice. The rounds already build more than one module for a program
   whose macros call macros, and the fix that day is to seed the counter from the module's index.
 
+- **The macro programs are not in the sanitizer sweep.** `test_sanitize.ml` runs an explicit list, not a glob, so
+  `macros.flan` and `macro-unless.flan` were not added to it by landing them. `dune build --root . @sanitize` is
+  clean as it stands; adding the two is a one-line edit in a file this lane did not own.

 - **No `&rest` sugar.** A macro takes one parameter, the slice of forms at its call site, and `(len args)` is the
   arity. That is deliberate — it is where variadics come from — but a `when` written against it reads worse than
   `parse.ml`'s version did.
