# Checkout main
git checkout main

# Merge worktree branch (--no-ff preserves history)
git merge ralph/{spec-name} --no-ff -m "feat: Implement {spec-name}

Merged from RALPH worktree:
- {summary of changes}

Stories completed:

# Delete branch
git branch -d ralph/{spec-name}

Error Handling

Error	Action

No worktrees	Direct to `/ralph-run`
Tests fail post-merge	Warn user, suggest `/ralph-qa`
Branch already deleted	Skip branch deletion

Conflict Resolution

If conflicts occur:

code

╔════════════════════════════════════════════════════════════════╗
║                    Merge Conflicts                              ║
╚════════════════════════════════════════════════════════════════╝

Conflicts in 2 files:
  ✗ src/types/index.ts
  ✗ src/services/auth.service.ts

Options:
  1. Resolve conflicts now (I'll help)
  2. Abort merge (keep worktree)
  3. Accept theirs (worktree version)
  4. Accept ours (main version)

Use AskUserQuestion to determine resolution strategy.
