- brain/graph/learn-loop.sh: rebuild+cluster -> (LLM-tier) deep-extract corpus
-> merge -> measure & heuristically optimize (orphan rate, community balance,
size) -> record metrics.json + learnings.md -> sync to Windows
- brain/corpus/{diagrams,designs,notes}/: drop sources for the brain to learn
- cron agentic-os-brain-rebuild now runs the learn-loop (compounding)
- README documents the learning tiers (offline structural vs LLM semantic)
Verified: 614 nodes, 1024 links, 0.2% orphans after optimization; no node loss.
