+## Purpose
+
+This is the cosmic-brain demo vault. It demonstrates the [[LLM Wiki Pattern]] — a system for building persistent, compounding knowledge bases using Claude and Obsidian.
+
+Run `/wiki` to scaffold this vault for your own domain and replace this overview.
+

+
+## Current Seed Content
+
+This vault ships with a seeded first ingest based on Nate Herk's breakdown of the Karpathy LLM wiki pattern.
+
+**Concepts seeded:**
+- [[LLM Wiki Pattern]] — the core architecture
+- [[Hot Cache]] — session context mechanism
+- [[Compounding Knowledge]] — why the pattern works
+
+**Entities seeded:**
+- [[Andrej Karpathy]] — originated the pattern
+
+**Sources seeded:**
+- [[Nate Herk LLM Wiki Transcript]] — practical demonstration of the pattern
+
+---
+
+## Current State
+
+- Sources ingested: 1
+- Wiki pages: 11
+- Last activity: 2026-04-07 (cosmic-brain v1.1.0 initialized)

+
+## Key Themes
+
+**Knowledge compounds.** Unlike RAG, the wiki pre-compiles synthesis. Cross-references are already there. Contradictions are flagged. Every ingest enriches existing pages rather than adding isolated chunks.
+
+**The hot cache is the force multiplier.** A ~500-word file captures recent context. New sessions start with full context at minimal token cost.
+
+**Obsidian is the IDE, Claude is the programmer.** The graph view shows what's connected. The human curates sources and asks questions. Claude writes and maintains everything else.
