+# 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.
