Development record

06-delivery/02-verification-matrix.md:26 says a second install at the same version gives a transparent re-confirm of visibility. A second abcd ahoy install prints nothing about visibility and no non-test source under internal/core/ahoy contains such a step; the already_up_to_date headline (install_summary.go:425) does not mention it either. The matrix's preamble says rows without (staged) describe the binary today.
