Research direction

Start by checking out the linked rama commit and reproducing cargo check --all --all-targets --all-features with Rust 1.77.1, both with and without existing compiler cache contents. Read the linked error output and determine whether the failure is reproducible; done means identifying a minimized reproduction or documenting that the issue no longer occurs after the relevant cache state is cleared.
