## [Unreleased]

### Added — Sprint 1 (Auth + CRUD Engagement)

**Backend** (Flask + SQLAlchemy + SQLite, 63 pytest passing)
- `User` model with `admin / redteam / soc` enum, argon2 password hashing.
- `Engagement` model with `planned / active / closed` status, FK to creator user.
- JWT Bearer auth (`PyJWT`, HS256, 60-min TTL), `@login_required` and `@role_required(*roles)` decorators.
- 13 API endpoints: `/api/auth/{login,logout,me}`, `/api/users` CRUD (admin-only with last-admin protection), `/api/engagements` CRUD (RBAC per role), `/api/health`.
- Alembic migration applied at container boot by `docker/entrypoint.sh`.
- `flask create-admin` CLI with duplicate-username and short-password validation.
- Engagement serializer returns `created_by={id, username}` (not bare User object).
- SPA fallback returns JSON 404 for unknown `/api/*` paths (no HTML leakage).

**Frontend** (React + Vite + TailwindCSS + TanStack Query, 20 vitest passing)
- Inter font bundled locally via `@fontsource-variable/inter` (no CDN at runtime).
- Tailwind config maps the `DESIGN.md` token system (palette, typography, spacing, radii).
- Pages: `LoginPage`, `EngagementsListPage`, `EngagementFormPage` (new+edit), `EngagementDetailPage` (Sprint 2 placeholder), `UsersAdminPage`.
- Components: `Layout`, `ProtectedRoute` (auth + role gate), `StatusBadge`, `FormField`, `LoadingState`/`ErrorState`/`EmptyState`, `Toast` + provider.
- Axios client with Bearer interceptor; 401 → token purge + redirect `/login` + "Session expirée" toast (AC-2.6); 403 → "Accès refusé" toast (AC-3.7).
- TanStack Query hooks: `useAuth`, `useEngagements`, `useUsers`, `useToast`.

**Deployment**
- Single-container `docker/Dockerfile` (multistage: `node:20-alpine` → `python:3.12-slim`).
- `docker/entrypoint.sh` running `flask db upgrade && flask run`.
- `Makefile` with `build`, `start`, `stop`, `restart`, `update`, `logs`, `create-admin`, `update-mitre` (no-op placeholder for Sprint 2), `test-backend`, `test-frontend`, `test-e2e`, `clean`.
- `.env.example` documenting `MIMIC_JWT_SECRET`, `MIMIC_DB_PATH`, `MIMIC_PORT`.
- SQLite persisted at `/data/mimic.sqlite`, volume `mimic-data` survives `make restart`.

**Acceptance tests** (Playwright, 36 specs, all 27 ACs covered)
- `e2e/` scaffold: `playwright.config.ts`, `fixtures/{auth,api}.ts`, 6 spec files (one per user story).
- Suite is portable via `MIMIC_CONTAINER_CMD` / `MIMIC_BASE_URL` env vars (works with `docker` or `podman`).

**Docs**
- `README.md` with quick-start, architecture overview, project layout, make target reference, and dev workflow.
- `pyrightconfig.json` at repo root pointing the Python LSP to `backend/.venv` and adding the worktree root to `extraPaths` for absolute imports.

### Changed
- 2026-05-26 — `admin` role widened in `SPEC.md` § Décisions techniques. The initial draft restricted admin to user-management only; after the Sprint 1 plan review surfaced the operational pain (admin would need a second `redteam` account just to manage engagements), the user decided to make admin a super-user that cumulates redteam rights on engagements/simulations.

### Removed
- _none_

---

## [Sprint 0] — Bootstrap (merged 2026-05-26)

### Added
- Initial `SPEC.md` covering project scope, simulation model, workflow, stack, and agent team.
- Technical decisions section in `SPEC.md`: 3-role auth (admin/redteam/soc), JWT Bearer, single-container Flask+React, local MITRE STIX bundle, minimal Engagement model, admin bootstrap via Makefile target.
- Sub-agent definitions under `.claude/agents/` for backend-builder, frontend-builder, spec-reviewer (project override of the built-in, covers plan-vs-spec and code-vs-spec), code-reviewer, test-verifier, devil-advocate.
- Project tracking scaffold: `tasks/todo.md`, `tasks/lessons.md`, `CHANGELOG.md`, `.gitignore`.
