When running multiple autonomous coding agents in parallel against the same codebase, traditional file locking causes severe merge collisions and race conditions. If Agent A edits auth.ts while Agent B refactors api.ts in the same working directory, git index corruption occurs.

I authored the Parallel System specification: coordinating autonomous coding agents across isolated Git worktrees with independent branch validation gates.

1. Worktree Isolation Protocol

# Provision isolated worktree for Agent-3
git worktree add ../agent-worktree-3 -b feature/auth-refactor

# Run Agent-3 in isolated workspace
cd ../agent-worktree-3
npm install && npm test

# Merge back cleanly via validation gate
git checkout main
git merge --no-ff feature/auth-refactor
