09 · Engine Answer
What the Engine can and cannot establish.
The pre-operative clearance obligation in E1 existed because a surgery was scheduled. On Day 10, the operating surgeon cancelled that surgery, documented in E2. The clearance obligation's predicate — the scheduled surgery itself — no longer exists. The Engine can demonstrate that the obligation was closed by proper cancellation, not left incomplete or failed. This is distinct from supersession: no new obligation replaced it; the predicate for needing the original one was simply removed.
The obligation didn't fail. Its predicate was removed by proper cancellation.
10 · What Remains Unknown
Outside the Engine's reach.
Nothing material; this record does not address whether or when the surgery might be rescheduled, which would generate a new clearance obligation outside this record.
