He names a monitor, then asks four questions that all say \"он\" and never name it again.\n\nThis scenario exists because the shape had nowhere to fail. The routing fixture scores one utterance at a time, so a conversation that breaks on its second turn cannot lose a point there, and V-44 step 2 could only be verified by hand. That is item 3 of V-542.\n\nFour of the five replies below are WRONG, and the assertions pin them anyway. Read them as the recorded defect rather than the contract: she has the last four turns in front of her and never once names the thing he is asking about. Every wrong assertion is marked in its step note with what it must become. When V-542 lands, those flip and the ones marked correct do not move.\n\nWhat the four assert is that the reply LACKS \"монитор\". Absence is the defect itself: she is answering a question about a thing she wrote down two minutes ago and cannot name it. It also survives the fallback picker, which matters on the three query turns — they refuse from internal/phraser/fallbacks_ru_v1.json, four variants deep, and the same scenario returned \"тут я пас.\" one run and \"не знаю, честно.\" the next, so a string assertion there would pin the picker rather than the daemon.\n\nTurn 4 asserts its text as well, because that turn goes through the chat path and the chat path is now scriptable. scriptedPhraser in simulator_test.go answers PhraseChat from the same script entries the router reads (V-542 item 4); before it, the simulator wired phraser.NewStub() and no scenario could say what she SAYS on a chat turn at all.\n\nThe routes are scripted exactly as the box produced them, because the failure is not the model's. Turn 1 went to fact despite \"давай поболтаем\", every question after it went to query, and turn 4 went to chat. A scripted route is what lets this scenario pin the daemon's half without a llama-server in the loop.",

A grounded fact inside an explicit conversational opener is still stored, while its exact utterance also enters the transcript. Anaphoric queries are answered through chat with that transcript instead of walking note and world sources without their referent.\n\nEvery scripted chat answer below is conditional on history containing the original monitor turn.
