NPCs who target the same resource or site concurrently gain mutual familiarity +0.1 per encounter, capped at 1.0. Action selection now receives the full NPC array and adds a +0.3 utility bonus for actions that familiar NPCs are currently performing - NPCs gravitate toward their housemates' professions. Inspector shows the highest-familiarity NPC with a percentage score under the resource lines.
