/**
 * Drift-guard for bug #3195: quick.md and execute-phase.md must both use
 * the git-history-based resurrection guard (WAS_DELETED check), not the
 * inverted PRE_MERGE_FILES grep form that deletes brand-new files.
 *
 * The PRE_MERGE_FILES form was fixed in execute-phase.md by PR #2510 but
 * the same bug remained in quick.md. This test ensures both workflows stay
 * in sync going forward.
