Run a full coherence sweep across the Brain Dependency Graph - computes staleness, lifecycle transitions, structural health, and generates a report
Compute lifecycle scores for all insight and framework notes - detect which notes are crystallizing or becoming generative
Autonomous research pipeline - discover, extract, and integrate cutting-edge insights into knowledge base
Detect productive contradictions between notes - high semantic similarity with opposing conclusions that represent synthesis opportunities
Autonomous perception layer - scans KB for new notes matching domain watch configs, checks gap resonance with the Thinking Registry, probes external signals via web search, and auto-activates HIGH/MEDIUM signals into the Thinking Registry for the incubation loop.
Extract insights from external documents (research papers, books, articles). Spawns document-insight-extractor subagent. Requires session name.
