voice.go is still the biggest file in cmd/mavend and most of what is left has nothing to do with the audio path. The ecosystem integration is one such lump: it talks to Nexus, Praxis and Hexis over HTTP and only touches the handler for its store and clock. Lifting it into ecosystem_acts.go puts it next to ecosystem.go, where the clients it drives already live. Move-only: handlePraxisAct, recordPraxisTrace (called from nowhere else), handleHexisAct and execHexis verbatim, plus the two imports that became unused in voice.go.
