# ADR 0013: Pipe And Pubsub ## Status Accepted. ## Decision Pipe resources will use authorized Iroh streams for stdin/stdout-style byte streams and forwarding. Pubsub will use lossy gossip for wakeups, presence, status, and ephemeral notifications. Pubsub is not authoritative storage. Important facts must live in durable resources such as kv, document, db, CAS manifests, or future auth logs. ## Consequences The modules can support ad hoc workflow and presence without confusing gossip with durable state.
