 Go's `\b` is ASCII-only and never fires after a Cyrillic letter; the pattern needs an
 explicit `(\s|[?!.]|$)`.
 
+Two more shapes taken off the model, 04-08-2026 (V-498). `rest-of-day-query` inside
+`AgendaQueryGrammars` claims "что дальше?" / "what's next", and `NarrativeQueryGrammar`
+(`stage0.go`, wired **last** in `buildRouter`, after the capture marker) claims "расскажи про
+X", "объясни X", "опиши X". Neither carries a question mark or an interrogative, so the model
+called both `IntentFact`; the write was caught downstream by `IsQuestionShaped`, so this was a
+latency and fixture defect, not a correctness one. The narrative rule reads the same
+`narrativeRequests` lexicon `IsQuestionShaped` reads, and declines `chatNarrativeTopics` — a
+joke, a bedtime story, herself — because the query chain has no source that answers those.
+New fixture cases ru-query-024 and ru-query-025. Classifier + ONNX baseline **56/80 (70.0%) →

+llama-server in that run), so judge it again before quoting a cascade number.
