+
+## Why it exists
+
+Provide a local, durable, inspectable transport for direct messages between agent workers running in tmux, with strict repository targeting, explicit endpoint lifecycle, bounded retry behavior, and future interoperability with coordination-engine.
+
+## Governing principle
+
+This repository should stay focused on the purpose above. Work that changes its
+authority, ownership boundaries, or operational promises should be captured in a
+workplan before implementation.
+
+## What it enables
+
+- Agent workers can address one another by registered repository slug.
+- Messages, leases, delivery state, and acknowledgements survive process restarts.
+- Operators can inspect, export, replay, and purge local queue history.
+- A later coordination-engine adapter can use a stable local socket boundary
+  without absorbing tmux-specific concerns into the coordination engine.
