Silent non-closure

Silent non-closure is the failure mode where clinical work is requested but never confirmed done.

It is "silent" because no alert fires — the request simply never closes, and nobody is told. It is "non-closure" because the work may have been completed, or it may not have been; either way, the system of record does not know.

This is the core problem Semblance exists to solve: making every clinical request verifiably closed, with an owner, a due time, and evidence of completion.
