Run scripts/import_yinduzhanxing.py --apply from a clean clone of upstream main 5fb8379c, the upstream HEAD on 2026-11-04. Only the root SKILL.md moves into references/upstream/yinduzhanxing; the six semantic-merge paths stay review_required and untouched. The new mirror drops the private "yn-1993" sample wording the b9a0ef8f mirror still carried. source-manifest.json and import-plan.json now pin 5fb8379c. The b9a0ef8f import record stays as history and its test now checks only the record.
