"""
Unit tests for the pr-queue-worker upstream fork auto-sync section.

Run:  python3 scripts/test_pr_queue_sync.py

No network, no GitHub token, no real git: `gh_api`, `_sync_git`, the Claude
runner and the push helper are monkeypatched so the worker's *orchestration*
(merge path, conflict path, protected-branch path, CI verify/revert, gating and
state bookkeeping) is exercised deterministically. The git mechanics themselves
are covered by the live E2E (`--sync-only <repo> --dry`), not here.
