Task 004: Auth And Admin/Editor Roles

Development description: Implement simple internal authentication and role-based authorization for the two v1 roles: Admin and Editor.

Implementation Details

• Add a local-demo authentication mode suitable for Docker Compose:
  • Header-based user selection for local demo, or
  • Session login with seeded users.
• Enforce role checks at backend endpoint boundaries.
• Role capabilities:
  • Admin can edit target sites, publishing YAML/scripts, prompt versions, and runner profiles.
  • Editor can create and run article pipelines, edit intermediate outputs, approve content, and create publish commits.
• Add frontend role-aware navigation:
  • Admin sees site configuration and script versioning screens.
  • Editor sees pipeline execution and review screens.
• Ensure authorization failures return stable 403 responses.

Public Interface

• Backend identifies current user and role for each request.
• Frontend can fetch GET /api/me.
• Protected endpoints consistently allow or deny Admin/Editor actions.

Acceptance Criteria

• TDD pre-requirement: before implementation, write one failing public API authorization test for an Editor attempting an Admin-only action; proceed one permission behavior at a time and record red-green evidence in Result.
• GET /api/me returns the active user and role.
• Admin can create/update site config and script versions.
• Editor cannot create/update site config or script versions.
• Editor can create articles and perform review actions.
• Unauthorized requests are rejected consistently.
• Frontend hides Admin-only navigation for Editors.

Verification

• Run backend authorization tests.
• Run frontend role rendering tests.
• Manually verify Admin and Editor demo sessions in Docker Compose.

Result

• Status: Completed.
• TDD plan:
  • First behavior slice: public FastAPI HTTP authorization denial for a demo Editor attempting an Admin-only site configuration mutation.
  • Public API contract selected for local demo auth: X-Demo-User-Email: editor@example.com.
  • Red test: POST /api/sites with an Editor-selected demo user must return stable 403.
  • Green slices: GET /api/me, Admin allow/Editor deny for site config and script version mutations, Editor article create and plan approval review action, stable 401/403 responses, and role-aware frontend navigation.
• Red evidence:
  • Command: docker compose run --rm --build -v /Users/gavrilovdev/tmp/pupline:/app -w /app backend python apps/backend/tests/integration/test_auth_authorization_public_api.py
  • Result: failed as expected because POST /api/sites and auth/role checks are not implemented yet.
  • Output:

• Refactor notes:
  • Added local demo auth via X-Demo-User-Email using seeded users.
  • Kept role constants in domain, current-user/site-config orchestration in application, repository persistence in infrastructure, and FastAPI dependencies/guards in presentation.
  • Added minimal plan approval review action endpoint for Task 004 role checks.
  • Added FSD role navigation model/component and a deterministic Node test that executes the TypeScript source.
  • Regenerated packages/shared/openapi.json and packages/shared/src/api-types.ts.
• Verification output:
  • docker compose run --rm --build -v /Users/gavrilovdev/tmp/pupline:/app -w /app backend python -m unittest discover apps/backend/tests
