Phase A of the multi-environment evolution agreed in the erp repo design thread. Both modules gain an optional env coordinate that defaults to "prod"; by the elision rule, env=prod produces the existing single-env derived names character-for-character, so every existing app's tofu plan should be a no-op. app_roles (per-instance module — caller iterates over envs): - variables.tf: add optional env = "prod" - main.tf: compute local.instance via elision rule + local.owner_role (snake-case <name>_<env>_role for the Postgres owner) - main.tf: substitute local.name -> local.instance in all derived names (dynamic role name, k8s role name, SA bindings, token_policies) - outputs.tf: add env + instance outputs; kvv2_path_prefix now derives from local.instance (== local.name when env=prod -> backwards-compat) app_policy (per-repo module — accepts list of envs): - variables.tf: add optional envs = ["prod"] - main.tf: compute local.instances + local.non_prod_instances - main.tf: refactor kvv2 ops rules to dynamic blocks iterating local.instances preserving the original rule order (data, delete, undelete, destroy, metadata) so prod-only apps render a byte-identical policy document - main.tf: allowed_parameter blocks for k8s role's bound_service_account_* and token_policies use comprehensions over local.instances - main.tf: keep vault_policy.app (the env=prod runtime policy) at its original address; add vault_policy.app_non_prod via for_each over non_prod_instances for the other envs Top-level wiring: - iac/variables.tf: add envs = optional(list(string), ["prod"]) to the applications set(object) type - iac/main.tf: pass envs = each.value.envs through to app_policies `tofu validate` passes. Every existing app's tofu plan should report no changes because: (1) env="prod" defaults are used everywhere, (2) the elision rule makes local.instance == local.name for prod, (3) dynamic rule blocks preserve declaration order, (4) the new app_non_prod resource is created via for_each over an empty set when no non-prod envs are declared. Phase B (factory postgres iac + argocd + runbook docs) and Phase D (erp iac/main.tf for_each + activate sandbox) follow in their own PRs.

Vault
- Les playbooks ansible configurent la base de données postgres et le minimum requis pour permetre au dépot "tools" d'appliquer via un workflow gitea action une configuration vault via tofu.
- Configuration des backend d'authentification et des roles pour postgres et kubernetes. Définition de rôles "${app}-ops" pour permettre au dépot d'une application de définir ses propres dépendances dans vault. Rotation de credentials postgres pour les applications.
- Le dépot de l'application webapp gère l'obtention de ses crédentials pour postgres.
