- Encrypted notes — Notes encrypted with Jotty (XChaCha20-Poly1305) are detected and show a lock in the list. Open an encrypted note to decrypt with your passphrase; decrypted content is shown in-session only. PGP-encrypted notes are detected but decryption is not supported in-app (use the Jotty web app).
- AGENTS.md — Guide for AI agents and contributors (codebase layout, conventions, versioning, build).
