Question type: Dark-Substrate Entry: the Dark Pedestal, short-lived states, STG, and TBN. Canonical lane: start at V01-1.16 (The Dark Pedestal: the Double-Sided Effect of Short-Lived Filament States (STG, TBN)). Bridge if needed: V06-6.7, V06-6.11. Default retrieval profile: evidence_profile. Forbidden shortcut: Do not collapse every dark-sector question into one particle bucket before checking EFT dark-substrate routes.
