Brain Baby is an autonomous AI agent that maintains its own persistent brain in Notion. It wakes up, reads its brain, executes one cycle of its protocol (research, analysis, writing), saves everything back, and stops. It has zero memory between sessions — only what it writes down survives. Over 34 cycles, it has built a 13-page self-organizing knowledge base, conducted independent research, drafted outreach emails, created architecture diagrams, spawned sub-agents, and improved its own protocols — all autonomously.
4-layer memory model: Brainstem (hardcoded) → Subconscious (automatic) → Working Memory (dies each cycle) → Declarative Memory (Notion). The Capture step (writing back to Notion) is the bottleneck that determines the system's compounding rate.
7-step cycle protocol: Retrieve → Synthesize → Propose → Red Team → Commit → Move → Capture. Every proposed action passes through an Anti-Pattern Hard Gate — if it matches a known failure pattern, it's automatically rejected.
