ADR-0002 Phase B. Makes postgres/iac, argocd, and the conventions docs
multi-environment-capable WITHOUT activating any sandbox yet — every app
stays prod-only, so this change is behaviour-neutral:
- postgres/iac `tofu plan` is a no-op (proven: the elision flatten keys
are bare app names, db=<app>, role=<app>_role — identical addresses)
- the argocd apps.yaml render is byte-identical (181→181 lines, diff
empty) since no app declares `envs`
postgres/iac:
- variables.tf: `applications` becomes set(object({name, envs=optional(["prod"])}))
- main.tf: a `local.app_instances` flatten of applications × envs keyed by the
elided instance id (env=prod → "<app>"); per-app resources iterate it and
reference each.key / each.value.{database,role}. For prod-only apps every
resource address + attribute is unchanged. (main.tf also got a full
`tofu fmt` pass — the pgbouncer function block reindents 4→2 spaces, which
is cosmetic; the correctness gate is the CI tofu plan, not the text diff.)
- terraform.tfvars: string entries → { name = "..." } objects.
argocd/templates/apps.yaml:
- after the prod Application, a `range $app_attr.envs` loop renders one extra
Application per non-prod env: name/namespace `<app>-<env>`, shared repoURL,
helm.valueFiles [values.yaml, values-<env>.yaml], per-env syncPolicy override.
Renders nothing while no app sets `envs` → prod render unchanged.
docs:
- doc/runbooks/new-web-app/conventions.md (FR, authoritative): new section
"Plusieurs environnements pour une même app" — elision rule, suffix rule,
snake-case owner-role exception, erp/erp-sandbox table, ADR-0002 link.
- vibe/guidebooks/lab-ecosystem/naming-conventions.md (EN mirror): the env
coordinate section + a "Two sandbox models" section reconciling the
separate-cluster (ADR-0001, names repeat) vs in-cluster sibling (ADR-0002,
<env> suffix) strategies; Last Updated bumped; ADR-0002 cross-links.
Activation (erp gets envs=["prod","sandbox"] in postgres tfvars + argocd
values + erp/iac) is Phase D, gated by its own plan review.

Document, as a tree-docs tree, the end-to-end procedure to stand up a new
web application on the Arcodange platform — a mechanic spread across the
factory, tools and app repos with non-trivial ordering dependencies.
Covers: Gitea repo creation (org-secret inheritance), Postgres DB + owner
role (factory/postgres/iac), platform Vault declaration (gitea_cicd_<app>
+ policies, tools/hashicorp-vault/iac), the app Helm chart (VSO dynamic
secrets via pgbouncer), the app Terraform (app_roles module), the CI
workflows (tofu apply + image build, incl. the copy-pasted role pitfall),
and ArgoCD registration (factory/argocd/values.yaml). Adds a naming-
conventions concept page and an ordered checklist.
Wires the legacy doc/adr "setup hello world web app" item and the factory
README to the runbook. New docs live under doc/ (singular) per the PR #8
convention.

The 20260509 ADR landed in docs/adr/ (plural) by mistake. Convention
is doc/adr/ (alongside the existing 00_*, 01_*, … docs and the
network-architecture/cicd-architecture ADRs that pre-existed there).
Note : 20260407-*.md files in the typo'd docs/adr/ are still untracked
(never committed) — separate cleanup task.
