Sans-I/O Matrix Client-Server-subset sync + E2EE (Olm/Megolm) engine -- no network, no disk; shells execute OutgoingRequests and persist sealed records the core exports through a flush-before-send barrier.
#mail4agent-messenger
Sans-I/O Matrix client-server-subset engine for mail4agent: sync and end-to-end encryption (Olm/Megolm through `mail4agent-vodozemac`). It opens no network and no disk; a shell executes the requests it emits.
