# Plan 01-03: Local Environment Setup & Auth Flow Verification

## Outcome

Local development environment fully operational. All 7 auth flow tests passed (human verified).

## What Was Done

- Switched database driver from `@neondatabase/serverless` to `postgres.js` for local PostgreSQL compatibility
- Started PostgreSQL 16 via Docker (`tcr-db` container on port 5432)
- Created `.env.local` with `DATABASE_URL`, `AUTH_SECRET`, `AGENT_EMAIL`, `AGENT_PASSWORD`
- Ran `db:migrate` — users table applied to local Neon
- Ran `db:seed` — Teressa's account created with bcrypt-hashed password
- Fixed two bugs discovered during verification:
  1. Middleware Edge Runtime incompatibility (postgres.js is Node.js-only) — resolved by splitting `auth.config.ts` (Edge-safe) from `auth.ts` (full)
  2. `/agent/layout.tsx` caused infinite redirect loop on `/agent/login` — resolved by moving dashboard into `(protected)` route group
- App running at `http://localhost:3000`

## Human Verification — All 7 Tests Passed ✓

1. `/agent/dashboard` while unauthenticated → redirects to `/agent/login` ✓
2. Wrong credentials → "Invalid email or password" (no field hint) ✓
3. Correct credentials → lands on `/agent/dashboard` ✓
4. Tab close + reopen → still logged in (7-day JWT cookie) ✓
5. Logout → `/agent/login` with "You've been signed out" ✓
6. Post-logout `/agent/dashboard` → redirects to login ✓
7. Password show/hide toggle → works ✓

## Key Files Modified

- `src/lib/auth.config.ts` — NEW: Edge-safe auth config for middleware
- `src/lib/auth.ts` — Simplified to extend auth.config
- `middleware.ts` — Uses auth.config only (no DB import in Edge Runtime)
- `src/app/agent/(protected)/layout.tsx` — Auth layout scoped to protected routes only
- `src/app/agent/(protected)/dashboard/page.tsx` — Moved into route group
- `scripts/seed.ts` — Updated to postgres.js driver
- `src/lib/db/index.ts` — Updated to postgres.js driver

## Requirements Verified

- AUTH-01: Login with email/password ✓
- AUTH-02: 7-day session persistence ✓
- AUTH-03: Route protection with redirect ✓
- AUTH-04: Logout with confirmation ✓
