ADR-0002 Phase D, final step. Adds `envs: { sandbox: {} }` to the erp entry
in argocd/values.yaml, so the Phase B per-env loop in templates/apps.yaml
renders an extra Application "erp-sandbox":
- source: same erp repo + chart, overlaid with values.yaml + values-sandbox.yaml
- destination namespace: erp-sandbox (CreateNamespace=true)
- syncPolicy: automated prune + selfHeal (default)
GitOps activation: on merge to main, the factory app-of-apps re-renders and
ArgoCD creates the erp-sandbox Application, which deploys the Dolibarr chart
into the erp-sandbox namespace. The pod's VSO reads the Vault paths created in
D2/D3 (auth/kubernetes/role/erp-sandbox, postgres/creds/erp-sandbox,
kvv2/erp-sandbox/config) and connects to the erp-sandbox DB created in D1.
Render verified: the only diff vs main is the added erp-sandbox Application;
prod erp + all other apps render byte-identical.
No DNS/TLS change needed (Phase E): *.arcodange.lab is a wildcard in Pi-hole
(CoreDNS forwards to it) and cert-manager holds a *.arcodange.lab wildcard set
as Traefik's default TLS — so erp-sandbox.arcodange.lab resolves + gets HTTPS
automatically once the ingress is up.
Completes Phase D. D1=factory#17, D2=tools#3, D3=erp#12 (all merged).
