 Decentralized agent memory for the Lightning economy. Store, query, and recall memories with cryptographic identity (Nostr) and micropayments (Lightning/L402).
 
 **The problem:** AI agents can transact via Lightning (L402) but can't remember what they paid for, which vendors are reliable, or their spending patterns. Lightning Memory fixes this.
