	# ============================================================
	# WorldScript Studio – Mutation Testing (Stryker) — Parallel + Incremental
	# QNBS-v3: Matrix-parallel Stryker with per-module caches and fail-safe aggregation.
	# Run manually via workflow_dispatch. Each matrix job targets one curated module;
	# runtime and score remain measured outputs rather than undocumented promises.
