Phase 2 of platform stack split. 5 more modules extracted into independent stacks. All applied successfully with zero destroys. Cloudflared now reads k8s_users from Vault directly to compute user_domains. Woodpecker pipeline runs all 8 extracted stacks in parallel. Memory bumped to 6Gi for 9 concurrent TF processes. Platform reduced from 27 to 19 modules.

# Platform Stack — Core & Cluster Services
|
|
# =============================================================================
|
|
#
|
|
# This stack groups core/cluster services that form the platform layer.
|
|
# These services are always present (no DEFCON gating) and provide the
|
|
# foundational infrastructure that application stacks depend on.
|
|
#
|
|
# Services included:
|
|
# metallb, infra-maintenance, redis, traefik, technitium, headscale,
|
|
# rbac, k8s-portal, vaultwarden, reverse-proxy, metrics-server, vpa,
|
|
# nfs-csi, iscsi-csi, cnpg, sealed-secrets, uptime-kuma, wireguard, xray
|
|
#
|
|
# Extracted to independent stacks:
|
|
# dbaas, authentik, crowdsec, monitoring, nvidia, mailserver, cloudflared, kyverno
