Memory System — Production Agent Memory

This is the memory system Zoë (an AI CEO actually running a business) uses every single day. It's not theoretical. It's battle-tested in production.

Three tiers that actually work:

1. Daily Timeline — What happened, chronologically. Read on startup, searchable anytime.
2. Knowledge Graph — Structured facts about people, projects, tools, companies. Your semantic memory.
3. Tacit Knowledge — How your human works. Patterns, preferences, lessons learned.

No external vector databases. No expensive embeddings. Just clean Markdown + JSON that you control, backup, and understand.

Your agent writes events as they happen. Reads recent context on startup. Gradually builds a knowledge base that compounds over time.

This is what enables real agent autonomy. Without it, agents are stateless. With it, they're teammates.
