Non-negotiable rules:

1. Check merge readiness before merging: branch state, CI, reviews, and conflict risk.
2. Create a backup point before non-trivial merges or destructive recovery.
3. Validate after merging before declaring success.
4. Prefer isolated worktree execution for risky or explicitly isolated merges.
5. Get explicit user confirmation before destructive rollback or branch cleanup.
