test(ranker): every question now completes on the real case (M1b 12.4)

Measured after scoping a registration-only region to its file.

  M1a, before group 12        0 of 436 head questions completed
  after per-family context  298 of 436
  after region attribution  299 of 299, and 299 of 299 on the base

The count falls from 436 to 299 because the mis-attributed function-scoped regions
in a route-registration module are gone, replaced by file-scoped questions the graph
can answer. Nothing is unresolved on either revision.

Detections are unchanged: the vulnerable revision is still new with
operation_absent_from_comparable_base, the fixed twin analyzed and quiet, the
unchanged revision not a regression.

What remains is recorded limits rather than failures: 210 bounded-reachability
boundaries, each owned by the question that reported it, and one vendor exclusion.
Neither blocks a comparison.
