- orchestrator: Tracer interface with spans for intent analysis, persona, subsession dispatch, context build, LLM streaming and each tool call; traces finish when the stream completes — the admin Trace waterfall finally receives data - background: Thinker generates real LLM thoughts (post-chat + silence triggers, recent history as context, empty/overlong outputs discarded); thoughts broadcast to web clients as 'thinking' WS messages; pipeline postChatHook triggers post-chat thinking after each round - memory: ApplyDecayAll + ListUserIDs with a 6h decay/purge cron in main (was implemented but never scheduled)
