+# Development TODO Plan
+
+## Phase 1 – Project Foundations
+
+- [x] Initialize Git hooks, linting, and formatting tooling (ESLint, Prettier, isort, black).
+- [x] Configure `pyproject.toml` or equivalent for backend dependency management.
+- [x] Scaffold FastAPI application entrypoint with health-check endpoint.
+- [x] Bootstrap React app with Vite/CRA, including routing skeleton and global state provider.
+- [x] Define shared TypeScript/Python models for core domain entities (tracks, stations, trains).
+- [x] Set up CI workflow for linting and test automation (GitHub Actions).
+
+## Phase 2 – Core Features
+
+- [x] Implement authentication flow (backend JWT, frontend login/register forms).
+- [x] Build map visualization integrating Leaflet with OSM tiles.
+- [ ] Create railway builder tools (track placement, station creation) with backend persistence APIs.
+- [ ] Establish train scheduling service with validation rules and API endpoints.
+- [ ] Develop frontend dashboards for resources, schedules, and achievements.
+- [ ] Add real-time simulation updates (WebSocket layer, frontend subscription hooks).
+
+## Phase 3 – Data & Persistence
+
+- [x] Design PostgreSQL/PostGIS schema and migrations (Alembic or similar).
+- [ ] Implement data access layer with SQLAlchemy and repository abstractions.
+- [ ] Seed initial data fixtures for development/demo purposes.
+- [ ] Integrate caching strategy (Redis) for map tiles and frequent queries.
+
+## Phase 4 – Testing & Quality
+
+- [ ] Write unit tests for backend services and models.
+- [ ] Add frontend component and hook tests (Jest + React Testing Library).
+- [ ] Implement end-to-end test suite (Playwright/Cypress) covering critical flows.
+- [ ] Set up load/performance testing harness for scheduling and simulation.
+
+## Phase 5 – Deployment & Ops
+
+- [ ] Create Dockerfiles for frontend and backend, plus docker-compose for local dev.
+- [ ] Provision infrastructure scripts (Terraform/Ansible) targeting initial cloud environment.
+- [ ] Configure observability stack (logging, metrics, tracing).
+- [ ] Document deployment pipeline and release process.
+
+## Phase 6 – Polish & Expansion
+
+- [ ] Add leaderboards and achievements logic with UI integration.
+- [ ] Implement accessibility audit fixes (WCAG compliance).
+- [ ] Optimize asset loading and introduce lazy loading strategies.
+- [ ] Evaluate multiplayer/coop roadmap and spike POCs where feasible.
