The boundary between durable and ephemeral memory is explicit: preferences, lessons, decisions, entity facts, and anything the user flags with 'remember this' goes to gbrain. Current tool versions, code path quirks, and facts that matter for only the next 1-3 sessions stay in Hermes memory. If it should compound across months or years, it belongs in the graph; if it expires this week, it belongs in scratch.
