Refresh CONTEXT.md against current repo + cluster reality (grill-with-docs):
- Module taxonomy rewrite: drop fictional k8s_app/helm_app/postgres_app
factory modules (never existed); name the real four (ingress_factory,
nfs_volume, anubis_instance, setup_tls_secret) + the shared / Stack-local
/ flat distinction; flag vestigial modules/kubernetes/<app> dirs.
- Rename "Ingress auth tier" -> "Ingress auth" (discrete modes, not tiers);
reserve "tier" for State tier + Namespace tier only.
- Add local-path entry (cluster default SC; node-local footgun warning).
- Add concepts: Keel, Diun, CNPG/pg-cluster, MetalLB LB-IP split, Calico.
- Add "policy" ambiguity flag (Kyverno vs Calico NetworkPolicy vs Vault/RBAC).
- Fix node count 5 -> 7 (k8s-master + k8s-node1..6).
Doc-sync (same commit per repo rules):
- overview.md: replace fictional factory modules with the real shared
modules + the flat/stack-local pattern.
- .claude/CLAUDE.md: drop dead nfs-proxmox column from the storage decision
table + stale cross-reference (vault migrated off it 2026-04-25).
