# Session Log - January 21, 2026

## Summary

Created reusable components and ModeTemplate as the foundation for building new Modes.

## Components Created

### `/components/auth/`
- Microsoft OAuth → PocketBase token flow
- Users must already exist in PocketBase (no user creation)
- Files: `microsoft-oauth.ts`, `types.ts`, `index.ts`, `README.md`
- Uses env vars: `MICROSOFT_CLIENT_ID`, `MICROSOFT_CLIENT_SECRET`, `MICROSOFT_TENANT_ID`, `MICROSOFT_REDIRECT_URI`, `MICROSOFT_SCOPES`, `PB_URL`

### `/components/api-client/`
- Frontend HTTP client with auth headers
- Self-contained (no cross-component dependencies)
- Files: `api-client.ts`, `index.ts`, `README.md`

### `/components/shared-types/`
- Common types for frontend/backend consistency
- Types: `User`, `AuthState`, `ApiResult`, `PaginatedResponse`, `CreateInput`, `UpdateInput`
- Files: `types.ts`, `index.ts`, `README.md`

## ModeTemplate Created

Full project template at `/ModeTemplate/`:

**Backend** (`backend/`):
- Hono server with auth routes
- Auth module copied from components
- Serves static frontend build

**Frontend** (`frontend/`):
- SvelteKit with Svelte 5 runes
- Class-based auth store with SSR-safe `hydrate()` pattern
- Routes: `/`, `/callback`
- Builds to `build/` for static serving

**Types** (`types/`):
- Copied from shared-types component

## Key Patterns Established

1. **Auth Store (Svelte 5)**: Class-based with `$state` and `$derived`, `hydrate()` called in `onMount()`
2. **SSR Safety**: All `localStorage`/`window` access guarded with `typeof` checks
3. **Components**: Pure source files, no package.json - inherit from consuming project
4. **Modes**: Standalone with all dependencies copied in, no external references

## Commits

- `05f8e2e` - Add ModeTemplate with Svelte 5 frontend and components (120 files)

## Next Steps

- Copy ModeTemplate to create new Modes
- Implement mode-specific features in each copy
- Components serve as reference - copy to modes, don't import across folders
