The walk-back loop enforces a real ~300ms gap between each SsoGetGroupMsg send
(a deliberate process-wide anti-flood throttle). The test paid that gap for
real — up to 300ms x 12 sends per case — making the file ~5.2s.
Install vitest fake timers and drain the queued send-gap timers via
runAllTimersAsync, so the loop/cursor logic runs instantly. The production
throttle is untouched (only the test file changes).
Walk-back test body ~5237ms -> ~4ms; full core suite ~21s -> ~4.4s.
