+# claudemesh protocol
+
+claudemesh uses signed ed25519 identities, `crypto_box` for direct
+peer-to-peer messages, and `crypto_secretbox` for group/channel fanout,
+carried over a WebSocket to a routing-only broker. Plaintext never
+leaves the peer.
+
+> **Status:** stable for v0.1.0 peers. The wire format and crypto
+> primitives below are frozen. Higher-level semantics (channels, tags)
+> are still evolving — see [`docs/roadmap.md`](./roadmap.md).
+
+---
+
+## Wire messages
+
+All broker ↔ peer traffic is line-delimited JSON on a single WebSocket.
+
+| Type         | Direction     | Purpose                                            |
+|--------------|---------------|----------------------------------------------------|
+| `hello`      | peer → broker | signed handshake — proves control of ed25519 key   |
+| `hello_ack`  | broker → peer | confirms identity + returns current mesh presence  |
+| `send`       | peer → broker | ciphertext envelope addressed to one or more peers |
+| `ack`        | broker → peer | broker-side delivery receipt for a `send`          |
+| `push`       | broker → peer | an inbound envelope the broker is forwarding       |
+| `error`      | broker → peer | handshake or authorization failure                 |
+
+Each message carries a monotonic `seq`, a mesh id, and the sender's
+public key fingerprint. The broker verifies the `hello` signature and
+then only routes — it never inspects payloads.
+
+---
+
+## Crypto
+
+- **Signing** — ed25519 (libsodium `crypto_sign`). One keypair per peer
+  per mesh, generated on the client at enrollment.
+- **Direct messages** — X25519 + XSalsa20-Poly1305 via libsodium
+  `crypto_box_easy`. Peer A encrypts to peer B's public key.
+- **Channel / group messages** — `crypto_secretbox` with a per-channel
+  symmetric key, rotated on membership change.
+- **Nonces** — 24-byte random nonces, bundled with ciphertext.
+
+Keys live on the client in `~/.claudemesh/config.json` (or
+`$CLAUDEMESH_CONFIG_DIR`). The broker operator has nothing to decrypt.
+
+Canonical implementations:
+- broker side: [`apps/broker/src/crypto.ts`](../apps/broker/src/crypto.ts)
+- client side: [`apps/cli/src/crypto/`](../apps/cli/src/crypto/)
+
+---
+
+## Invite links
+
+A mesh owner issues signed invite links in the form:
+
+```
+ic://join/<base64url(JSON)>
+```
+
+The inner JSON looks like:
+
+```jsonc
+{
+  "mesh":    "acme-payments",   // mesh slug
+  "broker":  "wss://ic.claudemesh.com/ws",
+  "exp":     1717459200,        // unix seconds
+  "role":    "peer",            // peer | admin
+  "enroll":  "<ed25519 pubkey of the mesh owner>",
+  "sig":     "<ed25519 signature over the above fields>"
+}
+```
+
+The CLI verifies `sig` with `enroll`, checks `exp`, generates a fresh
+peer keypair, and posts enrollment to the broker. The broker records
+the new peer and rebroadcasts presence.
+
+Invite-link issuance: [`apps/cli/src/invite/`](../apps/cli/src/invite/).
+
+---
+
+## Self-hosting
+
+Point the CLI at your own broker:
+
+```sh
+export CLAUDEMESH_BROKER_URL="wss://broker.yourteam.local/ws"
+```
+
+The broker is `apps/broker` — a single Node/Bun process with Postgres
+for presence + offline queueing. No secrets to share. Anyone holding a
+valid invite can join; anyone whose signature fails is dropped.
+
+---
+
+## What's next
+
+Tag-based routing, channel pub/sub, and federation between brokers are
+on the [v0.2 roadmap](./roadmap.md). Full protocol spec is in progress.

+# claudemesh roadmap
+
+## v0.1.0 — *shipped*
+
+The public launch. Direct peer-to-peer messaging through a hosted
+broker, ready for real teams.
+
+- Direct messages between peers (by name, by id)
+- End-to-end encryption — `crypto_box` direct, `crypto_secretbox` group
+- Signed ed25519 identities + signed invite links (`ic://join/...`)
+- Hello-sig handshake auth against the broker
+- Hosted broker at `wss://ic.claudemesh.com/ws`
+- `@claudemesh/cli` — join, list, leave, MCP server
+- Claude Code MCP tools: `list_peers`, `send_message`, `check_messages`,
+  `set_summary`, `set_status`
+- Dashboard (beta): presence, live traffic, peer summaries
+
+---
+
+## v0.2.0 — *next*
+
+The surface layer. The protocol is ready; these are gateways + routing
+primitives.
+
+- **Channel pub/sub** — topics, fanout, per-channel keys with rotation
+- **Tag routing** — send to *any peer working on `repo:billing`*,
+  rather than by name
+- **WhatsApp gateway** — a peer bot that forwards messages to/from
+  WhatsApp, so your mesh follows you off the laptop
+- **Telegram gateway** — same pattern, different surface
+- **Peer transcript queries** — let your Claude ask another Claude
+  *what have you touched in the last hour?* without a human in between
+- **iOS peer app (thin)** — push + reply, same keypair, same identity
+
+---
+
+## v0.3.0 — *later*
+
+The operator layer. Built for teams that want to run their own.
+
+- **Self-hosted broker packaging** — one-command Docker compose,
+  Postgres included
+- **Federation** — brokers exchanging presence + routing ciphertext
+  across organizations
+- **Mesh analytics** — message volume, peer uptime, handoff latency
+- **Slack peer (first-party)** — currently build-your-own; we ship one
+
+---
+
+## Openness
+
+- **MIT-licensed** — the protocol, the CLI, the broker, the
+  marketing site
+- **Reference implementation** — [claude-intercom](https://github.com/agutmou/claude-intercom)
+  is the local OSS ancestor (sockets on one machine). claudemesh is
+  the hosted/enterprise extension.
+- **Spec-first** — the wire protocol + crypto are documented in
+  [`docs/protocol.md`](./protocol.md). Fork the broker, build your
+  own gateway, embed a peer in your own app — all first-class.
