+# 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 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.

+# Environment and Deployment Runbook
+
+## Scope
+
+Operational baseline for `dev`, `staging`, and `production`.
+
+## Environments
+
+### Dev (local)
+
+- Runtime: Bun + local Next dev servers
+- Entry point: `bun run dev`
+- Database: local/remote dev Postgres from `.env`
+- Characteristics:
+  - fastest feedback
+  - non-production data acceptable
+  - migrations created here first
+
+### 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:
+  - protected secrets and stricter access controls
+  - immutable release artifacts
+  - rollback procedures required
+
+## Core Commands
+
+### Local development
+
+```bash
+bun install
+bun run db:generate
+bun run db:migrate
+bun run db:seed
+bun run dev
+```
+
+### Staging compose
+
+```bash
+bun run docker:staging:up
+bun run docker:staging:down
+```
+
+### Production compose
+
+```bash
+bun run docker:production:up
+bun run docker:production:down
+```
+
+## Release Flow
+
+1. Complete work on task branch.
+2. Merge into `dev` and pass quality gates.
+3. Promote `dev` -> `staging`.
+4. Validate staging smoke/e2e + manual checks.
+5. Promote `staging` -> `main` and tag release.
+
+## Migration Policy
+
+- Create migrations in development only.
+- Apply migrations in deployment using `prisma migrate deploy`.
+- Never hand-edit applied migration history.
+
+## Rollback Baseline
+
+Current baseline strategy:
+
+- rollback app image/tag to previous known-good release
+- restore database from backup when schema/data changes require recovery
+
+## Secrets and Config
+
+- Dev: `.env`
+- Staging: `.env.staging` (from `.env.staging.example`)
+- Production: `.env.production` (from `.env.production.example`)
+
+Minimum sensitive values:
+
+- `DATABASE_URL`
+- `BETTER_AUTH_SECRET`
+- `CMS_SUPPORT_*` credentials/keys
+
+## Verification Checklist
+
+- `bun run check`
+- `bun run typecheck`
+- `bun run test`
+- `bun run test:e2e`
+- app startup health for web/admin
+- login flow and permissions smoke

+# Git Flow Governance
+
+## Scope
+
+Governance rules for branch protections, PR gates, branch naming, and merge discipline.
+
+## Branch Protection
+
+Protected branches:
+
+- `main`
+- `staging`
+
+Apply protections using:
+
+- Gitea UI settings
+- or automation script: `.gitea/scripts/configure-branch-protection.sh`
+
+Minimum policy:
+
+- no direct pushes
+- PR merge required
+- required status checks
+- at least one reviewer approval
+
+## PR Gates
+
+Required checks are implemented in `.gitea/workflows/ci.yml`:
+
+- Governance Checks
+- Lint Typecheck Unit E2E
+
+## Branch Naming and TODO Scope
+
+Allowed branch prefixes:
+
+- `todo/`
+- `refactor/`
+- `code/`
+
+Validation script:
+
+- `.gitea/scripts/check-branch-name.sh`
+
+Rule:
+
+- one primary TODO item per delivery branch
+
+PR TODO reference enforcement:
+
+- template: `.gitea/PULL_REQUEST_TEMPLATE.md`
+- CI check: `.gitea/scripts/check-pr-todo-reference.sh`
+
+## Branch Lifecycle
+
+1. Create short-lived branch from latest integration tip.
+2. Implement one primary scope.
+3. Open PR and pass required checks.
+4. Merge into `dev`.
+5. Promote `dev -> staging -> main`.
+
+## Commit and Tag Policy
+
+- Conventional commits required (`CONTRIBUTING.md`)
+- release tags: `vX.Y.Z`
+- changelog generated from commit history

+# 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.

+### Authorization
+
+Permission check determining whether an authenticated actor can access a resource/action.
+
+### Pagination
+
+Mechanism for splitting large result sets across requests.
+
+### Idempotency
+
+Property where repeating a request does not change final state beyond the first successful call.
+
+### Rate Limit
+
+Request threshold policy applied per consumer/time window.
