Multi-agent integration patterns

Lesson 14 of Track 7 (Git Workflow: From Solo to Multi-Agent Teams). Three patterns for integrating work from parallel AI agents. Shared origin (simplest, most common). Per-agent fork (strongest isolation). Shared worktrees (fastest iteration, lead controls everything). How the lead orchestrates a fleet, runs integration, catches semantic conflicts that git cannot see, and produces a clean integration branch. By the end of L14 you can launch a multi-agent fleet, choose the right integration pattern, and avoid the failure modes that bite teams new to AI-collaborative development.
