Reproducer / smoke test

# No merge-conflict markers remain in state.md
grep -nE '^(<{7}|={7}|>{7})( |$)' docs/state.md || echo 'clean'
# -> clean

# No stale closed-bug rows in Open section
# (verify T-PYTHON-COMPARE, T-PYTHON-TRAIN-TEST, etc. absent from Open)
grep 'T-PYTHON-COMPARE-NO-BACKEND-PRECHECK\|T-PYTHON-TRAIN-TEST-STD-ZERO\|T-PYTHON-ROUTINE-SWALLOWED-EXCEPTION\|T-PYTHON-LOCAL-EXPLAINER-HACKY' docs/state.md | grep -v 'Recently closed\|_Updated'
# -> no output (all references are in Recently closed section only)
