The census arithmetic is settled by counting, not by which reading closes:
17 instances / 15 distinct, the mislocation being one defect over two instances,
so the session log was right and V2 §1.5 was wrong. My withdrawal of the
original flag was itself the error — it inferred a breakdown from a total, which
a total cannot settle. Yesterday's banked pattern: a number that matches is not
a cause; it produced two candidates and I accepted each in turn.
check_containment.py now carries the limit the PENDING-99 ruling exposed:
containment verifies that what you quoted is ACCURATE, never that you quoted
what MATTERS. An omission passes every time. The countermeasure is reading the
adjacent clauses, not a better checker.
