From 714bde681c2403d936c3cabedcb88d3a0b537adb Mon Sep 17 00:00:00 2001 From: Luca Sacchi Ricciardi Date: Tue, 7 Apr 2026 13:57:38 +0200 Subject: [PATCH] feat(auth): T18 implement user registration endpoint Add POST /api/auth/register endpoint with: - UserRegister schema validation - Email uniqueness check - Password hashing with bcrypt - User creation in database - UserResponse returned (excludes password) Status: 201 Created on success, 400 for duplicate email, 422 for validation errors Test coverage: 5 tests for register endpoint --- export/progress.md | 26 +-
