# Story 1.1: App Shell & First Launch Experience

Status: review

## Story

As a user,
I want to launch GitPulse and see a polished dark-mode dashboard with an empty state prompting me to configure scan roots,
So that I have a clear starting point.

## Acceptance Criteria

1. **Given** GitPulse is launched for the first time **When** no scan roots are configured **Then** the dashboard shows an empty state with a "Open Settings" CTA
2. **Given** the app is loaded **Then** the TopBar (48px) shows title, Grid/List toggle, filter area, rescan button, and PrivacyBadge placeholder
3. **Given** the app loads **Then** dark mode is the default with system fonts and 4px spacing grid
4. **Given** the user resizes or moves the window **Then** window position and size are persisted via tauri-plugin-store and restored on next launch
5. **Given** the app window **Then** minimum size is 800x600, default size is 1200x800

## Dev Notes

*(Preserved from story creation — see original for full details)*

### Architecture Compliance

- **Starter command:** Manually scaffolded (full control over structure)
- **Rust naming:** snake_case modules/functions, PascalCase structs — followed
- **React naming:** PascalCase components, camelCase hooks/stores — followed
- **IPC pattern:** Result<T, AppError> on Rust, safeInvoke<T> on TS — followed
- **Store pattern:** { data, status, error } — followed
- **No barrel files, no `any`, no `unwrap()`** — followed

## Dev Agent Record

### Agent Model Used

GLM-5.1

### Debug Log References

- Rust toolchain not installed: `rustc` not found in PATH. Frontend builds and tests pass. Rust compilation requires `rustup` installation.
- Vite production build: 168KB JS + 41KB CSS (gzip: 55KB + 8KB)

### Completion Notes List

- Project scaffolded manually with all dependencies installed (332 npm packages)
- All 14 unit tests pass (EmptyState: 5, TopBar: 4, utils: 5)
- Vite production build succeeds
- Rust backend source files created (error.rs, state.rs, commands/, lib.rs, main.rs)
- Frontend components created: Button, Dialog, Skeleton, TopBar, ViewToggle, PrivacyBadge, EmptyState
- Design token system established via Tailwind v4 CSS-first config (@theme block)
- Window persistence hook created with debounced save/restore via tauri-plugin-store
- Settings store with Zustand + typed Tauri IPC wrappers
- BLOCKER: Rust toolchain must be installed (`rustup.rs`) to compile and run `npm run tauri dev`

### Change Log

- 2026-04-25: Story 1.1 implementation complete. All frontend code, Rust backend source, tests, and configuration files created.
