Added allow-traefik-to-acme-solver NetworkPolicy to sso and mfa namespaces. The default-deny-all policy was blocking HTTP-01 challenge traffic from Traefik to the cert-manager solver pods, causing all TLS certs to stay pending (502). Workplan NK-WP-0003 updated: T02, T03, T04, T05, T06, T07, T08a all done on RAILIANCE01 as of 2026-03-25. T08 (e2e auth test) is now unblocked.
