Laravel 12 → 13 Upgrade Guide

Centralized upgrade path from Laravel 12.46 to Laravel 13.0 (released March 17, 2026).

Agent Workflow (MANDATORY)

Before ANY upgrade, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase — Audit current Laravel 12 patterns ($fillable, $tries, VerifyCsrfToken references)
2. fuse-ai-pilot:research-expert — Verify latest Laravel 13 docs via Context7 (/laravel/docs/13.x/upgrade)
3. fuse-laravel:laravel-expert — Apply Laravel 13 best practices

After upgrade, run fuse-ai-pilot:sniper for validation.
