What io.github.MaxFreedomPollard/engram does
Compartment is the memory your AI agents plug into. Hermes, Claude, and OpenClaw each register in one command; anything that runs a subprocess can use the CLI. Every agent can share the same memory - even across different machines. Everything is local. The default install never touches the network: the embedding model ships inside the package, so recall works as soon as the vault is open. Every byte at rest is AEAD-encrypted, the vectors included. The vault locks itself on restart or power loss
