Stage 5 dc0 Step 7: phase-03 core-API VERIFIED; F-CV2 openstack-client on rack; F-CV1/F-CV3 logged ...

Core-API layer of phase-03 core-verify (adapted for vr1-dc0, run from the dc0
rack per D-138) VERIFIED read-only: settle walk (falsifiable prediction matched),
haproxy 0-DOWN across 12 activated VIP apps, admin-openrc scoped token, IP-only
endpoints, two-sourced keystone VIP, vault CA TLS OK.

F-CV2 RESOLVED (07-30 queued-F1, hit at Step 7): installed python3-openstackclient
6.6.0-0ubuntu2 on the dc0 rack; CURRENT-STATE section 7 row amended (GA-R1/C1).

Exit gate NOT MET (2 open, GA-R6/E3 no conditional close): F-CV3 dashboard VIP
serves plaintext (apache-SSL-inactive despite certs) -> Horizon exit-gate fails;
Step 3.4 domain-manager policy NOT RUN. F-CV1 designate-api plaintext vs haproxy
check-ssl (same shape); "collateral of block" reading retracted. Logged not fixed.
