Alejandro Gutiérrez 81a8d0714b feat(crypto): client-side direct-message encryption with crypto_box
Direct messages between peers are now end-to-end encrypted. The
broker only ever sees {nonce, ciphertext} — plaintext lives on the
two endpoints.

apps/cli/src/crypto/envelope.ts:
- encryptDirect(message, recipientPubkeyHex, senderSecretKeyHex)
  → {nonce, ciphertext} via crypto_box_easy, 24-byte fresh nonce
- decryptDirect(envelope, senderPubkeyHex, recipientSecretKeyHex)
  → plaintext or null (null on MAC failure / malformed input)
- ed25519 keys (from Step 17) are converted to X25519 on the fly via
  crypto_sign_ed25519_{pk,sk}_to_curve25519 — one signing keypair
  covers both signing + encryption roles.

BrokerClient.send():
- if targetSpec is a 64-hex pubkey → encrypt via crypto_box
- else (broadcast "*" or channel "#foo") → base64-wrapped plaintext
  (shared-key encryption for channels lands in a later step)

InboundPush now carries:
- plaintext: string | null   (decrypted body, null if decryption failed
                              OR it's a non-direct message)
- kind: "direct" | "broadcast" | "channel" | "unknown"
MCP check_messages formatter reads plaintext directly.

side-fixes pulled in during 18a:
- apps/broker/scripts/seed-test-mesh.ts now generates real ed25519
  keypairs (the previous "aaaa…" / "bbbb…" fillers weren't valid
  curve points, so crypto_sign_ed25519_pk_to_curve25519 rejected
  them). Seed output now includes secretKey for each peer.
- apps/broker/src/broker.ts drainForMember wraps the atomic claim in
  a CTE + outer ORDER BY so FIFO ordering is SQL-sourced, not
  JS-sorted (Postgres microsecond timestamps collapse to the same
  Date.getTime() milliseconds otherwise).
- vitest.config.ts fileParallelism: false — test files share
  DB state via cleanupAllTestMeshes afterAll, so running them in
  parallel caused one file's cleanup to race another's inserts.
- integration/health.test.ts "returns 200" now uses waitFullyHealthy
  (a 200-only waiter) instead of waitHealthyOrAny — prevents a race
  with the startup DB ping.

verified live:
- apps/cli/scripts/roundtrip.ts (direct A→B): ciphertext in DB is
  opaque bytes (not base64-plaintext), decrypted correctly on arrival
- apps/cli/scripts/join-roundtrip.ts (full join → encrypted send):
  PASSED
- 48/48 broker tests green

@claudemesh/cli

Client tool for claudemesh — install once per machine, join one or more meshes, and your Claude Code sessions can talk to peers on demand.

Install

# From npm (once published)
npm install -g @claudemesh/cli

# Or from the monorepo during dev
cd apps/cli && bun link

Then register the MCP server with Claude Code:

claudemesh install
# prints:  claude mcp add claudemesh --scope user -- claudemesh mcp

Run the printed command, then restart Claude Code.

Join a mesh

claudemesh join ic://join/BASE64URL...

The invite link is generated by whoever runs the mesh. It bundles the mesh id, expiry, signing key, and role. Your CLI verifies it, generates a fresh keypair, enrolls you with the broker, and persists the result to ~/.claudemesh/config.json.

Commands

claudemesh install         # print MCP registration command
claudemesh join <link>     # join a mesh via invite link
claudemesh list            # show joined meshes + identities
claudemesh leave <slug>    # leave a mesh
claudemesh mcp             # start MCP server (stdio — Claude Code only)
claudemesh --help          # show usage

Env overrides

Var Default Purpose
CLAUDEMESH_BROKER_URL wss://ic.claudemesh.com/ws Point at a self-hosted broker
CLAUDEMESH_CONFIG_DIR ~/.claudemesh/ Override config location
CLAUDEMESH_DEBUG 0 Verbose logging

Status

v0.1.0 scaffold — CLI commands + MCP server shell in place. WS broker connection, libsodium crypto, invite-link verification, and auto-install of hooks land in subsequent steps.
