+## Last Updated
+2026-04-07 — cosmic-brain v1.1.0 initialized. First ingest complete: Nate Herk LLM Wiki transcript.
+
+## Key Recent Facts
+- The wiki pattern was originated by [[Andrej Karpathy]] and makes knowledge compound like interest
+- [[Hot Cache]] (this file) enables cross-project context at minimal token cost (~500 tokens)
+- [[Compounding Knowledge]] is the core insight: unlike RAG, the wiki pre-compiles synthesis
+- One user dropped token usage by 95% switching from inline context files to the wiki pattern
+- The index file alone is sufficient at hundreds of pages — no vector RAG needed
+
+## Recent Changes
+- Created: [[LLM Wiki Pattern]], [[Hot Cache]], [[Compounding Knowledge]], [[Andrej Karpathy]]
+- Created: [[Nate Herk LLM Wiki Transcript]] (first source)
+- Created: seed vault structure (index, log, overview, dashboard)
+- Plugin v1.1.0: added /save and /autoresearch commands
+
+## Active Threads
+- Vault is fresh. No user-specific domain scaffolded yet.
+- Next step: run /wiki to scaffold for your domain, then start ingesting sources.
