# Test Sta.cc and WorstSlack.cc uncovered code paths:
# - Sta::worstSlack(MinMax) single-arg form
# - WorstSlack queue-related operations
# - Sta::checkFanout on specific pin
# - report_tns, report_wns with corner variants
# - Sta::findDelays level form
# - various report_checks combos that exercise uncovered lines
# Covers: Sta.cc worstSlack, checkFanout, WorstSlack.cc
