NTS authenticated time is now bench-verified end-to-end unattended on a clean
build (comet-beacon-54, 5294860): chronyc -N authdata shows ntp.fleet.lab in NTS
mode with cookies > 0, sources read under enforcing SELinux, no lo.sources, no
manual step. This clears the two dispatcher-integration defects found on the way
(distro 20-chrony-dhcp clobber; /run/chrony-dhcp SELinux label).
Flips F-03/P-18 / R-17 from "bench-verify pending" to bench-verified in the SSP
status line + register and the Annex §2.9 control row + R-17 register + summary,
mirroring the F-02 treatment. Rated Low. Residual (defence-in-depth, not blocking):
issue the per-environment NTS server cert, and exercise the cold-clock
nocerttimecheck bootstrap + active-spoof rejection.
