content never moves. addresses do.

three nodes — a laptop, a phone, a cloud node — joined by stitch lines. envelopes travel between them while content dots stay fixed inside each node.sources stayon their hostsonly addresses syncverified identity readsexactly what it is granted

data does not move.

inseam indexes your email, files, chats, and records where they already live. the network syncs addresses and small envelopes — never content. there is no second silo to trust or pay for.

access is first-class.

an outside requester proves a property — email:you@example.com — and can discover exactly the sources carrying it. no user database anywhere; relevance and permission are the same question.

designed; the boundary is not built yet, and we say so.

plugins meant for ai to build.

everything the node does is a sandboxed plugin on a small typed seam. when a connector is missing, your own agent writes it and mounts it safely, minutes later — the first shipped plugin was written by an agent.

discovery is a ladder, not a dump.

query returns ranked addresses. expand and scan pull fragments from promising ones. fetch retrieves a full source only when it earns it — an agent gets progressively closer instead of twenty chunks up front.

the shape of a real session; paths are illustrative.

open source. extend it indefinitely.

the core is small and stays small: a kernel that runs plugins, and plugins for everything else. no company roadmap caps what it reaches — the community and your own agents write the long tail, and one conformance harness gates every install. the hosted node is an ordinary node with no special powers.
