+# Plan 01-03 Summary: Email/Password Authentication
+
+## Metadata
+
+- **Plan:** 01-03
+- **Phase:** 01-foundation-auth
+- **Started:** 2026-01-31
+- **Completed:** 2026-01-31
+- **Duration:** 0min (work already done by parallel plan 01-04)
+
+## Objective
+
+Implement complete email/password authentication flow with registration, login, email verification, and password reset.
+
+## Status: COMPLETE (via parallel execution)
+
+This plan was designed to run in parallel with 01-04 (Google OAuth). During execution, 01-04 completed first and implemented ALL of the code specified in this plan, including:
+
+- Validation schemas (src/lib/schemas/auth.ts)
+- Server actions (src/app/actions/auth.ts)
+- Auth pages (login, register, reset-password, update-password, verify-email)
+- UI components (button, input, card)
+- Auth callback route
+
+## Deliverables (created by 01-04)
+
+| File | Purpose | Lines |
+|------|---------|-------|
+| src/lib/schemas/auth.ts | Zod validation schemas | 39 |
+| src/app/actions/auth.ts | Server actions for auth | 164 |
+| src/app/(auth)/layout.tsx | Centered auth layout | ~10 |
+| src/app/(auth)/login/page.tsx | Login page | ~25 |
+| src/app/(auth)/register/page.tsx | Registration page | ~25 |
+| src/app/(auth)/verify-email/page.tsx | Email verification info | ~20 |
+| src/app/(auth)/reset-password/page.tsx | Password reset form | ~50 |
+| src/app/(auth)/update-password/page.tsx | New password form | ~50 |
+| src/components/auth/login-form.tsx | Login form component | ~60 |
+| src/components/auth/register-form.tsx | Register form component | ~70 |
+
+## Verification
+
+All must-haves verified present in codebase:
+
+- [x] User can register with email and password (registerUser action)
+- [x] User receives verification email after registration (emailRedirectTo configured)
+- [x] User cannot access app until email is verified (Email not confirmed error handling)
+- [x] User can log in with verified email/password (loginUser action)
+- [x] User sees specific error messages in Italian (custom error mappings)
+- [x] User can reset password via email link (resetPassword + updatePassword actions)
+
+## Technical Notes
+
+**Parallel Execution Context:**
+Wave 2 had two plans (01-03 and 01-04) that could run simultaneously. Due to timing, 01-04 executed first and created all auth infrastructure to support Google OAuth. Since email/password auth uses the same pages and components, 01-04 implemented everything that 01-03 would have.
+
+**No Duplicate Work:**
+Rather than re-creating files, this summary documents that all 01-03 requirements are satisfied by the existing code.
+
+## Commits
+
+No commits from this plan - all work was done by 01-04 commits:
+- `1d454d2`: feat(01-04): create Google Sign-In button component
+- `dcbd7e8`: feat(01-04): add Google button to login and register pages
+- `fc5e799`: docs(01-04): complete Google OAuth plan
+
+## Issues
+
+None - seamless parallel execution.
