Comment threads authored by someone other than the expected party ('summon_foreign') no longer always result in a flat publish_refused. The system now attempts to compose a genuine reply-only response as a fallback, unless paused by the foreign_fallback gate, and screens the composed text for hidden codepoints before posting.
Foreign-authored comment threads get a composed fallback reply instead of a flat refusal
Comment threads from an unexpected author now get a real composed reply instead of a flat refusal.
