# Selenium Grid NetworkPolicy.
#
# Captured into bluejay-infra 2026-05-07 during the regroup audit. This
# NetworkPolicy was previously applied via `kubectl apply` directly to
# the cluster with no source-of-truth anywhere — a fresh cluster rebuild
# would have lost all of it (including the Selenium Grid → Traefik VIP
# allow rule for AAT runs against `*.iamworkin.lan` services).
#
# The Selenium Grid Deployment + Services themselves are still managed
# outside ArgoCD (deployed via raw kubectl from the original Selenium
# Grid bring-up). Migrating those into bluejay-infra is a separate lane —
# this commit only restores GitOps repeatability for the NetworkPolicy.
#
# Rules captured from the live cluster's `kubectl get netpol -n selenium
# selenium-netpol -o yaml` on 2026-05-07. Originally applied 2026-03-15
# (from `metadata.creationTimestamp` before the field was stripped).
#
# Allows:
#   - Egress: CoreDNS, intra-namespace pod-to-pod (4442/4443/4444/5555),
#     Traefik VIP for `*.iamworkin.lan` AAT runs, all FC namespaces on
#     standard FC service ports (5100/5200/5300/5400/8080), pod CIDR
#     (10.42.0.0/16) + service CIDR (10.43.0.0/16) for the same ports,
#     LAN gateway range (10.0.56.0/24) for HTTPS, edge2 CUPS print
#     (10.0.57.16:5200), public internet 80/443 (excluding RFC1918), and
#     fc-signage:5190 for the signage AAT lane.
#   - Ingress: Traefik (4444 + 8089 ACME-solver-style), intra-pod,
#     telephony / gitea / fc-system / fc-signage namespaces on 4444.
