feat: sprint 1 — auth + CRUD engagements Ship the first feature end-to-end on the UI: users log in with JWT, admins manage user accounts, and any authenticated user (per RBAC) can create, list, view, edit, and delete engagements. Backend (Flask + SQLAlchemy + SQLite, 63 pytest) - User / Engagement models, Alembic 0001 initial schema - argon2 password hashing, JWT bearer (60-min TTL), @login_required and @role_required decorators - 13 API endpoints under /api/*, including last-admin protection on DELETE/PATCH user and JSON 404 on unknown /api/* paths - `flask create-admin` CLI with duplicate / short-password handling Frontend (React + Vite + Tailwind + TanStack Query, 20 vitest) - Inter font bundled locally (no CDN), DESIGN.md tokens in Tailwind - LoginPage / EngagementsList / EngagementForm / EngagementDetail / UsersAdmin pages with role-aware UI - Layout, ProtectedRoute, StatusBadge, FormField, LoadingState, ErrorState, EmptyState, Toast + provider - Axios client: Bearer interceptor, 401 → purge + /login + "Session expirée" toast, 403 → "Accès refusé" toast (declarative <Navigate> for already-authed users, Fragment-keyed admin user rows) Deployment - Single multistage Dockerfile (node:20-alpine → python:3.12-slim) - docker/entrypoint.sh runs `flask db upgrade` before `flask run` - Makefile: build/start/stop/restart/update/logs/create-admin/ update-mitre/test-{backend,frontend,e2e}/clean - .env.example documenting MIMIC_JWT_SECRET / MIMIC_DB_PATH / MIMIC_PORT - SQLite at /data/mimic.sqlite on named volume mimic-data Acceptance suite (Playwright, 36 tests, all 27 ACs) - e2e/ scaffold with playwright.config + auth/api fixtures - One spec per user story (us1-bootstrap through us6-deployment) - Portable via MIMIC_CONTAINER_CMD / MIMIC_BASE_URL (docker or podman) Docs - README.md with quick-start and architecture overview - CHANGELOG.md updated with Sprint 1 deliverables - pyrightconfig.json so the Python LSP sees backend/.venv and resolves the `backend.app.*` absolute imports Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
