Start with tests/test_closing.py at the test_htlc_no_force_close failure around line 4031 and reproduce the CI flake. Review the recorded channeld and min-relay-fee logs to determine why the final block generation does not complete reliably. Done means the test handles the observed behavior and passes consistently.
