# Count distinct commits already reviewed, never review state: the org ruleset
# sets dismiss_stale_reviews_on_push, so a push flips a prior APPROVED to
# DISMISSED and a state filter stops matching it. Inline comments each create
# their own COMMENTED review sharing the round's commit_id, so unique commit_id
# == round count, +/-1 when a push lands mid-round and splits it across two SHAs.
# Coupled to the reviewer's login: if that ever changes the count silently drops
# to 0 and every round looks like the first, hence the warning below.
