+# Versioning Policy
+
+## Source Of Truth
+
+- Canonical version: root `package.json` field `version`
+- Tag format: `vX.Y.Z`
+
+Tag validation is enforced in CI:
+
+- `.gitea/scripts/validate-tag-version.sh`
+
+## SemVer Strategy
+
+- `major`: breaking API/behavior changes
+- `minor`: backward-compatible features
+- `patch`: backward-compatible fixes
+
+## Build Metadata Policy
+
+Use git metadata in runtime display format:
+
+- `<version>+sha.<short>`
+
+Example:
+
+- `0.1.0+sha.a1b2c3d`
+
+## Footer Display Plan (Admin + Web)
+
+Planned runtime footer fields:
+
+- app name
+- version from root `package.json`
+- commit hash (short)
+- environment (`dev|staging|production`)
+
+Implementation note:
+
+- inject values at build/deploy time through env vars
+- render in shared footer components
+
+## CI Version Injection
+
+Release/deploy workflows pass release tag and commit metadata:
+
+- `.gitea/workflows/release.yml`
+- `.gitea/workflows/deploy.yml`
+
+Required inputs:
+
+- release tag (`vX.Y.Z`)
+- image tag for deployment
+
+## Validation Strategy
+
+CI validations:
+
+- tag equals `v${package.json.version}`
+- required checks pass before release builds
+
+Runtime validations (planned):
+
+- smoke tests assert footer version/hash format
+- environment-specific deployment checks assert expected image tag
+
+## Changelog and Release Publication
+
+- changelog generation command:
+  - `bun run changelog:release`
+- release workflow generates changelog on tag pipeline
+- release notes publication remains a dedicated step in CI workflow.

+# ADR 0001: Monorepo Foundation
+
+- Status: Accepted
+- Date: 2026-02-10
+
+## Context
+
+The CMS platform requires:
+
+- separate admin and public apps
+- shared domain contracts and data access
+- consistent tooling and CI quality gates
+- incremental delivery through MVP stages
+
+A fragmented multi-repo setup would increase coordination overhead and duplicate shared contracts.
+
+## Decision
+
+Adopt a Bun workspace monorepo with:
+
+- `apps/admin` and `apps/web` for runtime surfaces
+- shared packages (`@cms/content`, `@cms/db`, `@cms/crud`, `@cms/ui`, `@cms/i18n`)
+- shared quality tooling (Biome, TypeScript, Vitest, Playwright, Turbo)
+
+## Consequences
+
+### Positive
+
+- shared contract updates propagate in one change set
+- easier cross-app refactors and testing
+- single CI pipeline with consistent gates
+
+### Negative
+
+- stronger need for workspace discipline and clear boundaries
+- larger repository clone/build surface
+- potential for cross-package coupling if conventions are not enforced

+# CRUD Baseline
+
+## Scope
+
+MVP0 now includes a shared CRUD foundation package: `@cms/crud`.
+
+Current baseline:
+
+- Shared service factory: `createCrudService`
+- Repository contract: `list`, `findById`, `create`, `update`, `delete`
+- Service surface for list/detail/editor flows: `list`, `getById`, `create`, `update`, `delete`
+- Shared validation error type: `CrudValidationError`
+- Shared not-found error type: `CrudNotFoundError`
+- Shared mutation audit hook contract: `CrudAuditHook`
+- Shared mutation context contract (`actor`, `metadata`)
+
+## First Integration
+
+`@cms/db` `posts` now uses the shared CRUD foundation:
+
+- `listPosts`
+- `getPostById`
+- `createPost`
+- `updatePost`
+- `deletePost`
+- `registerPostCrudAuditHook`
+
+Validation for create/update is enforced by `@cms/content` schemas.
+Contract tests validate:
+
+- repository list/detail behavior via CRUD service
+- validation and not-found errors
+- audit payload propagation (`actor`, `metadata`)
+
+The admin dashboard currently includes a temporary posts CRUD sandbox to validate this flow through a real app UI.
+
+## Notes
+
+- This is the base layer for future entities (pages, navigation, media, users, commissions).
+- Audit hook persistence/transport is intentionally left for later implementation work.
+- Implementation examples are documented in `crud-examples.md`.

+# CRUD Examples
+
+## Goal
+
+Provide concrete implementation patterns for new entities adopting `@cms/crud`.
+
+## Example: Service Factory Wiring
+
+```ts
+import { createCrudService } from "@cms/crud"
+import { createPageInputSchema, updatePageInputSchema } from "@cms/content"
+
+const pageCrudService = createCrudService({
+  resource: "page",
+  repository: pageRepository,
+  schemas: {
+    create: createPageInputSchema,
+    update: updatePageInputSchema,
+  },
+  auditHooks: pageAuditHooks,
+})
+```
+
+## Example: Repository Contract
+
+```ts
+const pageRepository = {
+  list: () => db.page.findMany({ orderBy: { updatedAt: "desc" } }),
+  findById: (id: string) => db.page.findUnique({ where: { id } }),
+  create: (input: CreatePageInput) => db.page.create({ data: input }),
+  update: (id: string, input: UpdatePageInput) =>
+    db.page.update({
+      where: { id },
+      data: input,
+    }),
+  delete: (id: string) => db.page.delete({ where: { id } }),
+}
+```
+
+## Example: Action Usage
+
+```ts
+export async function createPage(input: unknown, context?: CrudMutationContext) {
+  return pageCrudService.create(input, context)
+}
+
+export async function updatePage(id: string, input: unknown, context?: CrudMutationContext) {
+  return pageCrudService.update(id, input, context)
+}
+
+export async function deletePage(id: string, context?: CrudMutationContext) {
+  return pageCrudService.delete(id, context)
+}
+```
+
+## Testing Expectations
+
+- validation failure returns `CrudValidationError`
+- missing IDs return `CrudNotFoundError`
+- repository methods are called in expected order
+- audit hooks receive `actor`, `metadata`, `before`, `after`
+
+## Adoption Checklist
+
+1. Add entity schemas in `@cms/content`
+2. Add repository + service in `@cms/db`
+3. Add unit tests for contract + validation
+4. Wire route/action permission checks before mutations
+5. Add docs links and TODO updates

+# Delivery Pipeline
+
+## Scope
+
+Operational pipeline baseline for image build/push, staging deploy, production promotion, and rollback.
+
+## Registry Credentials Strategy
+
+Use scoped Gitea secrets:
+
+- `CMS_IMAGE_REGISTRY`
+- `CMS_IMAGE_NAMESPACE`
+- `CMS_IMAGE_REGISTRY_USER`
+- `CMS_IMAGE_REGISTRY_PASSWORD`
+
+Policy:
+
+- credentials only in CI secrets
+- no plaintext credentials in repo
+- least privilege: push/pull for target namespace only
+
+## Build and Push Flow
+
+- Workflow: `.gitea/workflows/release.yml`
+- Trigger:
+  - tag push `vX.Y.Z`
+  - manual `workflow_dispatch`
+- Steps:
+  1. validate tag vs root `package.json` version
+  2. generate changelog
+  3. docker login
+  4. build and push `cms-web` and `cms-admin` images
+
+## Staging Deployment Automation
+
+- Workflow: `.gitea/workflows/deploy.yml`
+- Manual input:
+  - `environment=staging`
+  - `image_tag=vX.Y.Z`
+- Remote deployment uses SSH + compose file:
+  - `docker-compose.staging.yml`
+
+Required secrets:
+
+- `CMS_STAGING_HOST`
+- `CMS_STAGING_USER`
+- `CMS_DEPLOY_KEY`
+- `CMS_REMOTE_DEPLOY_PATH`
+
+## Production Promotion and Rollback
+
+Promotion:
+
+- run deploy workflow with:
+  - `environment=production`
+  - `image_tag=vX.Y.Z`
+
+Rollback:
+
+- release workflow supports rollback placeholder by image tag
+- deploy workflow supports `rollback_tag` input
+- recovery action:
+  - rerun deploy with previous known-good tag
+
+## Deployment Verification
+
+After deploy:
+
+1. app health checks (web/admin)
+2. auth smoke flow
+3. i18n smoke flow
+4. critical route checks (`/`, `/login`, `/todo`)
+
+## Notes
+
+- Current workflows are production-oriented scaffolds and require secret provisioning in Gitea.
+- Host hardening, network ACLs, and backup policy remain mandatory operational controls.

+
+### Staging
+
+- Runtime: Docker Compose (`docker-compose.staging.yml`)
+- Purpose: integration validation and release candidate checks
+- Characteristics:
+  - production-like environment
+  - controlled test data
+  - candidate for production promotion
+
+### Production
+
+- Runtime: Docker Compose (`docker-compose.production.yml`)
+- Purpose: end-user traffic
+- Characteristics:

+# i18n Conventions
+
+## Scope
+
+This document defines translation conventions for both apps in MVP0+.
+
+- Public app i18n: `next-intl` message namespaces and route-level usage
+- Admin app i18n: JSON dictionaries + runtime resolver/provider
+- Shared locale contract: `@cms/i18n` (`de`, `en`, `es`, `fr`; default `en`)
+
+## Locale Policy
+
+- Source of truth: `packages/i18n/src/index.ts`
+- Current enabled locales are code-driven and shared across web/admin.
+- Admin-managed locale toggles are planned for a later MVP.
+
+## Key Naming Conventions
+
+- Use `camelCase` for keys.
+- Group by domain namespace (not by component filename).
+- Keep keys stable; update values, not key names, during copy edits.
+
+### Public app namespaces
+
+- `Layout.*`
+- `Home.*`
+- `LanguageSwitcher.*`
+- Page-specific namespaces, e.g. `About.*`, `Contact.*`
+- Metadata namespace: `Seo.*`
+
+### Admin app namespaces
+
+- `common.*`
+- `auth.*`
+- `dashboard.*`
+- `settings.*`
+
+## Message Structure
+
+- Keep messages as nested JSON objects.
+- Avoid very deep nesting (prefer 2-3 levels).
+- Keep punctuation in translation values, not code.
+- Avoid embedding HTML in message strings.
+
+## Fallback Rules
+
+- Unknown/invalid locale values fallback to default locale `en`.
+- Missing translation key behavior:
+  - Admin: `translateMessage` returns provided fallback, else key.
+  - Public: ensure required keys exist in locale JSON; avoid runtime missing-key states.
+
+## Adding New Translation Keys
+
+1. Add key/value in `apps/*/src/messages/en.json`.
+2. Add equivalent key in `de/es/fr` JSON files.
+3. Use key via translator:
+   - Web: `useTranslations("Namespace")` or `getTranslations("Namespace")`
+   - Admin: `useAdminT()` or server-side `translateMessage(...)`
+4. Add/adjust tests for behavior where relevant.
+
+## Translation Workflow
+
+1. Author English source copy first.
+2. Add keys in all supported locales in same change.
+3. Keep semantic parity across locales.
+4. Run checks:
+   - `bun run check`
+   - `bun run typecheck`
+   - `bun run test`
+5. For route-level i18n behavior changes, run e2e smoke:
+   - `bunx playwright test --grep "i18n smoke"`
+
+## QA Checklist
+
+- Locale switch persists after refresh.
+- Page headings and navigation labels translate correctly.
+- Metadata (`Seo`) strings resolve per locale.
+- No missing-key placeholders visible in UI.
+

+# Testing Strategy Baseline
+
+## Goals
+
+- Keep lint, typecheck, unit/integration, and e2e as mandatory quality gates.
+- Make e2e runs deterministic by preparing schema and seeded data before test execution.
+- Keep test data isolated per environment (`dev` local, CI database service in workflow).
+
+## Current Gate Stack
+
+- `bun run check`
+- `bun run typecheck`
+- `bun run test`
+- `bun run test:e2e`
+
+## Data Preparation
+
+- `bun run test:e2e:prepare` runs:
+  - Prisma client generation
+  - migration deploy
+  - seed data (including support user bootstrap)
+- `bun run test:e2e` and related scripts call `test:e2e:prepare` automatically.
+
+## Locale Integration Coverage
+
+- `e2e/i18n.pw.ts` covers:
+  - web locale switch + persistence
+  - admin locale switch + persistence
+
+## CI
+
+- Real quality workflow: `.gitea/workflows/ci.yml`
+- Uses a PostgreSQL service container and runs the full gate stack, including e2e.
