# Phase 01 Plan 01: Project Setup and Database Schema Summary

**SvelteKit project with Tailwind CSS v4, Drizzle ORM, and unified entries table for task/thought storage**

## Performance

- **Duration:** 4 min 20 sec
- **Started:** 2026-01-29T03:30:20Z
- **Completed:** 2026-01-29T03:34:40Z
- **Tasks:** 2
- **Files modified:** 16 created, 3 modified

## Accomplishments

- SvelteKit minimal template with TypeScript and Svelte 5
- Tailwind CSS v4 configured with @tailwindcss/vite plugin
- Drizzle ORM schema defining unified entries table
- Database scripts for schema management (db:push, db:generate, etc.)
- All dependencies installed (better-sqlite3, nanoid, zod)

## Task Commits

Each task was committed atomically:

1. **Task 1: Create SvelteKit project with dependencies** - `3a2e0f2` (feat)
2. **Task 2: Configure Drizzle schema with entries table** - `63c5e4b` (feat)

## Files Created/Modified

- `package.json` - Project dependencies and db scripts
- `vite.config.ts` - Tailwind plugin configuration
- `src/app.css` - Tailwind import
- `src/routes/+layout.svelte` - CSS import and layout
- `src/routes/+page.svelte` - Test page with Tailwind classes
- `src/lib/server/db/schema.ts` - Drizzle schema with entries table
- `src/lib/server/db/index.ts` - Database connection with WAL mode
- `drizzle.config.ts` - Drizzle kit configuration

## Decisions Made

- Used Tailwind CSS v4 with @tailwindcss/vite (latest approach, not PostCSS)
- Unified entries table with type discriminator ('task' | 'thought') rather than separate tables
- SQLite with better-sqlite3 for simple single-file database
- WAL mode enabled for better read concurrency

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

- `sv create` interactive prompts required CLI flags (--no-add-ons, --no-dir-check)
- drizzle-kit push requires data directory to exist first (created manually)

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Foundation complete with all dependencies
- Database schema ready for CRUD operations
- Ready for Plan 02 (API endpoints) and Plan 03 (UI components)
