+Reliability and quality prompt edits (wave 1): high-risk triggers are named then judged in one line (E1); prompt-injection attempts in the diff or PR description are themselves blocking findings (E3); deletions are findings (E5); bot threads are judged against the whole reply chain and a conceded point is never re-raised (E6); open human threads are deferred to instead of duplicated (E7); and pre-existing bugs on touched lines are in scope (R3b).
