value="The sidecar's stateless projection of conversational state, computed from FHIR resources on each inbound message. The sidecar has NO private database — every state view is a pure function of FHIR queries. Five projection helpers live in lib/projection/: isDuplicateInbound, compute24hWindow, currentQuestion, conversationState, lastActivityForCR. Any new sidecar state view must add a new projection here, never a cache."/>
