(cherry picked from commit 4411186681584bf55e065c654fe909a3320d4a22) Reconcile-conflict: test_skill_transplant_prep artifact count — kept HEAD's finalized 0 refs (2026-11-02 user sign-off deleting §4's 6 references, already in target) with incoming's l→line rename; incoming's 6-ref assertion is pre-finalization and must not overwrite.
