Research direction
Start with slides/thread/mtqueue.hpp and inspect std::optional try_pop_until, then compare the condition-variable wait call with the function’s deadline-based behavior. Confirm the timeout behavior remains correct for callers and that the repository’s available checks pass; done means the function uses the intended wait semantics without changing unrelated queue behavior.
