AGENTS.md — navigation

Header global for main site navigation. Provides the Header Payload global and tRPC procedures for dynamic navigation content.

What it owns

• Entities — Navigation type (title, links, menu items)
• Use cases — Get header, update header
• Repository interface — INavigationRepository for navigation persistence
• Mock repository — In-memory navigation store for tests
• Payload repository — Real Payload-backed navigation repository (constructor-injected at boot)
• Payload global — Header global definition
• tRPC router — Procedures for get header
• DI container — Per-feature InversifyJS container with navigation symbols
• UI components — Navigation menu, header with branding

Public exports

From package.json:

• . — Navigation type + UI components (NavigationMenu, Header)
• ./api — tRPC router (navigationRouter)
• ./cms — Payload Header global
• ./di/bind-production — bindProductionNavigation() to wire Payload repo at boot

What it must NOT import

• Any other feature package (@repo/auth, @repo/blog, etc.)
• Any app package
• @repo/core-api, @repo/core-cms, @repo/core-trpc, @repo/core-ui directly; only import from @repo/core-shared and use DI for Payload config

Layer rules

src/ files use relative imports

// ✓ Correct
import type { INavigationRepository } from "../repositories/navigation.repository.interface.js";

// ✗ Wrong
import { Navigation } from "@/entities/navigation.js";

Tests use @/ alias

// ✓ Correct
import { getHeaderUseCase } from "@/application/use-cases/get-header.use-case.js";

DI container is per-feature

Tests rebind:

import { container as navContainer, NAV_SYMBOLS } from "@/di/container.js";
import { MockNavigationRepository } from "@/infrastructure/repositories/mock-navigation.repository.js";

beforeEach(() => {
  navContainer.unbindAll();
  navContainer.bind(NAV_SYMBOLS.INavigationRepository).to(MockNavigationRepository);
});

Test conventions

• Unit tests colocated: *.test.ts
• Feature tests in tests/: *.feature.test.ts
• Vitest environment — node
• Alias — @/ resolves to src/
• Run — pnpm test --filter @repo/navigation

Structure (minimal)

Per spec addendum v5 ("create folders only when needed"), this feature is small:

src/
  entities/
    navigation.ts            # Navigation/Header schema
  application/
    repositories/
      navigation.repository.interface.ts
    use-cases/

No application/use-cases/ subdirectory; just one or two use-cases at the top level.
