Why: Probes sent with page.request do not raise page response events, so
the §11-8 leak scan only covered passive page responses.
Evidence: Final run 20261016T065123Z item8-scan.json counted 18 responses,
all passive; probe bodies were checked only for rejection and payload.
Impact: Every probe and host API body is scanned for project A names, the
controlled and uncontrolled document titles and review markers.
