Twice today (runs 40301239508, 40311712302) mob_ai failed in parity-main, passed when bisect ran it again at the same HEAD, and the run still ended red, so no game release could follow main for three hours. The harness step now continues on error and the bisect step gives the verdict: 0 when every failed harness passes again at HEAD, 1 when they fail at the base too or a merge is named.

# The vanilla harnesses on main, a batch of merges at a time (docs/release-flow.md#parity-on-main), on the Mac mini's
|
|
# runner. One run at a time: merges that land while a run goes on wait in one pending run (GitHub keeps only the
|
|
# newest), which checks every merge since main's last green parity-main (tools/parity_main.py base). On a failure it
|
|
# bisects the failing harnesses over those merges and comments on the pull request that broke them. Releases ship
|
|
# only a commit whose parity-main passed (tools/release_train.py), so nothing a harness catches reaches players.
