Scope.

.{p20 is a correction release of p19 with no scope expansion. It follows the findings of the p19 independent rebuild (PASS with findings; report sha256 1b01f1d8, bound to tree fcf90354{} and zip da924275; same box, not a second machine). There is no contract revision, and the p15–p18 layers are byte-identical. The disclosed p20 revisions of the p19 layer are defect.py and release_p19.py. bulk_symmetry_restored is false regardless. O.1 stays NOT_CLOSED; the insertion stays frozen; XV-B and XIV-J are unopened; Route B is not discharged; no $c\delta$ is added to ${u^R}_{\mu }$.}
