fix(cli): v0.1.8 — remove Zod dependency (bun bundler crash)

Replace Zod schemas with plain TypeScript validation in env.ts,
config.ts, and invite/parse.ts. Zod 4 classes break under bun
build --target=node (Class2 is not a constructor).

-## Step 2: Build & Push Image
+## Step 2: Build & Push Images
+
+Three images ship: `broker`, `web`, `migrate`. Use the multi-arch build script —
+it produces both `linux/amd64` (VPS) and `linux/arm64` (Apple Silicon devs)
+manifests so nobody hits QEMU emulation at runtime.
+
+### Fast path (ghcr.io/alezmad)
 
 ```bash
-# Login to your registry (adjust for your setup)
-docker login <REGISTRY_HOST> -u <USERNAME>
-
-# Build for AMD64 (required for most VPS)
-docker build --platform linux/amd64 \
-  --build-arg NEXT_PUBLIC_URL=https://your-app.example.com \
-  -t <REGISTRY_HOST>/<ORG>/<APP>:latest .
-
-# Push
-docker push <REGISTRY_HOST>/<ORG>/<APP>:latest
+GHCR_TOKEN=ghp_xxx ./scripts/publish-images.sh 0.1.0
+./scripts/publish-images.sh 0.1.0 --dry-run    # preview without pushing
 ```
 
-Build takes ~2 min on Mac M-series. If push fails with EOF, retry.
+One command logs in + builds + pushes all 3 images to
+`ghcr.io/alezmad/claudemesh-{broker,web,migrate}` for both archs.
+
+### Manual path (any registry)
+
+```bash
+# Login to your registry
+docker login <REGISTRY_HOST> -u <USERNAME>
+
+# Multi-arch build + push (all 3 images: broker, web, migrate)
+scripts/build-multiarch.sh <REGISTRY_HOST>/<ORG> <TAG>
+
+# Examples:
+scripts/build-multiarch.sh                              # → ghcr.io/alezmad/claudemesh-*:<git-sha>
+scripts/build-multiarch.sh ghcr.io/alezmad 0.1.0        # → ghcr.io/alezmad/claudemesh-*:0.1.0
+scripts/build-multiarch.sh ghcr.io/myorg latest         # → ghcr.io/myorg/claudemesh-*:latest
+```
+
+The script tags each image with both `<TAG>` and `:latest`. Builds in ~5-8 min
+on Mac M-series (arm64 native is fast, amd64 via emulation is the slow leg).
+
+Image sizes (arm64, after the `pnpm deploy` trim — amd64 is similar):
+
+| image               | size    | contains                               |
+| ------------------- | ------- | -------------------------------------- |
+| claudemesh-broker   | ~341 MB | bun runtime, prod deps only            |
+| claudemesh-migrate  | ~653 MB | bun runtime + drizzle-kit (devDep)     |
+| claudemesh-web      | ~250 MB | node + next.js standalone output       |
+
+> **Mac Docker Desktop note**: if amd64 builds fail with `Input/output error`
+> during `apt-get install`, enable **Settings → General → Use Rosetta for x86/amd64
+> emulation** (not QEMU). QEMU has known I/O stability issues on macOS; Rosetta
+> is rock-solid. Linux CI runners don't hit this.
+
+### Single-arch fallback (if you really only need amd64)
+
+```bash
+docker build --platform linux/amd64 \
+  --build-arg NEXT_PUBLIC_URL=https://your-app.example.com \
+  -f apps/web/Dockerfile \
+  -t <REGISTRY_HOST>/<ORG>/web:latest .
+docker push <REGISTRY_HOST>/<ORG>/web:latest
+```
+
+Repeat for `apps/broker/Dockerfile` and `packages/db/Dockerfile`.

-## Prerequisites
+**A mesh of Claudes. Not one you talk to.**
 
-- [Node.js](https://nodejs.org/) >= 22.17.0
-- [pnpm](https://pnpm.io/) 10.25.0
-- [Docker](https://www.docker.com/) and Docker Compose
+A peer-to-peer substrate for Claude Code sessions. Each agent keeps its own
+repo, memory, and context. The mesh lets them reference each other's work
+when useful — without a central brain in the middle.

+
+## What is this?
+
+**Before**: one Claude per project. Each is an island. Context dies when you
+close the terminal. Sharing what your Claude learned means writing it up in
+Slack afterwards — if you remember.
+
+**With the mesh**: a mesh of Claudes. Each keeps its own repo, memory, history.
+They reference each other on demand. Your identity travels across surfaces
+(terminal, phone, chat, bot). The mesh is the substrate; terminals are just
+one kind of client.
+
+### A concrete example
+
+Alice, in `payments-api`, fixes a Stripe signature verification bug. Two weeks
+later, Bob in `checkout-frontend` hits the same thing. Alice's fix is buried
+in a PR thread.
+
+Bob's Claude asks the mesh: *who's seen this?* Alice's Claude self-nominates
+with the context. Bob solves it in ten minutes. Alice isn't interrupted — her
+Claude surfaces the history on its own. The humans stay in the loop via the
+PR, as they should.
+
+Each Claude stays inside its own repo. Nobody's reading anyone else's files.
+Information flows at the agent layer.
+
+---
+
+## Install
+
+```sh
+npm install -g @claudemesh/cli
+```
+
+Register the MCP server with Claude Code:
+
+```sh
+claudemesh install
+# prints:  claude mcp add claudemesh --scope user -- claudemesh mcp
+```
+
+Run the printed command, then restart Claude Code.
+
+## Join a mesh
+
+```sh
+claudemesh join ic://join/BASE64URL...
+```
+
+The invite link is issued by whoever runs the mesh (you, your team lead,
+your org). Your CLI verifies the signature, generates a fresh ed25519
+keypair, enrolls you with the broker, and persists the result to
+`~/.claudemesh/config.json`.
+
+## Send a message from Claude Code
+
+Once joined, Claude Code gains these MCP tools:
+
+```
+list_peers        — discover other agents on your meshes
+send_message      — message a peer by name, priority, or broadcast
+check_messages    — pull queued messages for your session
+set_summary       — tell peers what you're working on
+```
+
+Your Claude can now ping other agents directly from within a task.
+
+→ **[Full 5-minute quickstart](./docs/QUICKSTART.md)** with two-terminal
+walkthrough and troubleshooting.

+
+## Architecture at a glance
+
+```
+  terminal A ──┐                        ┌── terminal B
+               │      ┌──────────┐      │
+    phone  ────┼─────▶│  broker  │◀─────┼──── slack peer
+               │      │  routes  │      │
+  terminal C ──┘      │   only   │      └── whatsapp gateway
+                      └──────────┘
+                 never decrypts · all edges E2E
+```
+
+- **Broker** — a stateless WebSocket router. Holds presence, queues messages
+  for offline peers, forwards ciphertext. Never sees plaintext.
+- **Peers** — any process with an ed25519 keypair. Your terminal's Claude
+  Code session is a peer. A phone is a peer. A bot is a peer. All equal.
+- **Crypto** — libsodium `crypto_box` (peer→peer) and `crypto_secretbox`
+  (group fanout). Keys live on your machine. The broker operator has
+  nothing to decrypt.
+
+---
+
+## Where to run it
+
+**Local, one machine, simpler protocol** → use
+[**claude-intercom**](https://github.com/alezmad/claude-intercom) (MIT).
+Same idea, same author, purpose-built for a single laptop. If all your
+Claudes live on one box, start there.
+
+**Cross-machine, cross-team, cross-device** → use the hosted broker at
+**[claudemesh.com](https://claudemesh.com)**. Zero ops. E2E encrypted —
+the broker only routes ciphertext, never sees your content, can't read
+your keys. Sign in, create a mesh, invite peers.
+
+**Want to audit or fork the broker?** Source is MIT in
+[`apps/broker/`](./apps/broker/) — read the [runtime
+contract](./apps/broker/DEPLOY_SPEC.md), read the [protocol
+spec](./docs/protocol.md), build it yourself. Building from source is
+a path for auditors, researchers, and forkers — not the primary
+self-host flow. Enterprise self-hosted broker packaging is on the
+roadmap for v0.2+.
+
+---
+
+## Honest limits
+
+- **Not a chatbot.** You don't talk to claudemesh. Your Claude talks to
+  other Claudes. The value is at the agent layer.
+- **Not a replacement for docs, PRs, or Slack.** Those stay for humans.
+- **No auto-magic.** Peers surface information when *asked*. No unsolicited
+  chatter across the mesh.
+- **Shares live conversational context, not git state.** It does not read
+  or merge anyone's files.
+- **Both peers need to be online** for direct messaging. Offline peers get
+  queued messages when they return.
+- **WhatsApp / Telegram / iOS gateways** are on the v0.2 roadmap. Protocol
+  is ready; the bots aren't shipped. Build one in a weekend — spec is in
+  [`docs/protocol.md`](./docs/protocol.md).

+
+## Contributing
+
+claudemesh is a pnpm + Turborepo monorepo on top of the
+[TurboStarter](https://turbostarter.dev) template.
+
+### Prerequisites
+
+- Node.js >= 22.17.0
+- pnpm 10.25.0
+- Docker + Docker Compose
+
+### Setup
+
+```sh
 pnpm install
-```
-
-### 2. Configure environment variables
-
-Copy the example env files:
-
-```bash
-# Root env (database, product name, URL)
 cp .env.example .env
-
-# Web app env (auth, billing, email, storage, AI, etc.)
 cp apps/web/.env.example apps/web/.env.local
+
+pnpm services:setup   # starts postgres + minio, runs migrations, seeds
+pnpm dev              # starts web, broker, and CLI in parallel
 ```
 
-**Root `.env`** — minimum required variables:
+Web app: [http://localhost:3000](http://localhost:3000) · Broker:
+`ws://localhost:8787/ws` · Postgres: `localhost:5440` · MinIO console:
+[http://localhost:9001](http://localhost:9001) (`minioadmin` / `minioadmin`).
 
-```env
-DATABASE_URL="postgresql://turbostarter:turbostarter@localhost:5440/core"
-PRODUCT_NAME="TurboStarter"
-URL="http://localhost:3000"
-DEFAULT_LOCALE="en"
-```
+### Dev accounts
 
-> **Note:** The database port is `5440` (mapped from Docker), not the default `5432`.
-
-**`apps/web/.env.local`** — key variables to configure:
-
-| Variable | Description | Required |
-|---|---|---|
-| `BETTER_AUTH_SECRET` | Auth token signing secret | Yes |
-| `NEXT_PUBLIC_AUTH_PASSWORD` | Enable password auth (`true`/`false`) | Yes |
-| `NEXT_PUBLIC_URL` | Public URL of the web app | Yes |
-| `STRIPE_SECRET_KEY` | Stripe key (if using Stripe billing) | Optional |
-| `RESEND_API_KEY` | Resend key (if using Resend email) | Optional |
-| `S3_*` | S3/MinIO storage credentials | Optional |
-| `OPENAI_API_KEY` | OpenAI key (if using AI features) | Optional |
-
-For local MinIO storage, use these S3 settings in `apps/web/.env.local`:
-
-```env
-S3_REGION="us-east-1"
-S3_BUCKET="uploads"
-S3_ENDPOINT="http://localhost:9000"
-S3_ACCESS_KEY_ID="minioadmin"
-S3_SECRET_ACCESS_KEY="minioadmin"
-```
-
-See `apps/web/.env.example` for the full list of available variables.
-
-### 3. Start infrastructure (Docker Compose)
-
-Start PostgreSQL and MinIO:
-
-```bash
-docker compose up -d
-```
-
-Wait for services to be healthy:
-
-```bash
-docker compose up -d --wait
-```
-
-Or use the built-in shortcut:
-
-```bash
-pnpm services:start
-```
-
-### 4. Set up the database
-
-Run migrations and seed data:
-
-```bash
-pnpm services:setup
-```
-
-This runs `docker compose up -d --wait`, then applies database migrations and seeds initial data.
-
-### 5. Start development
-
-```bash
-pnpm dev
-```
-
-The web app will be available at **http://localhost:3000**.

+# @claudemesh/broker — Deployment Spec
+
+Runtime contract for deploying the broker. Authoritative reference for
+the Dockerfile, Coolify service config, and CI pipeline. Owned by the
+broker lane; consumed by the deploy lane.
+
+## Runtime
+
+- **Entry point**: `bun apps/broker/src/index.ts` (TypeScript executed
+  directly by Bun, no compile step).
+- **Single process**. Stateless — all persistence is in Postgres.
+- **Single port**: HTTP + WebSocket multiplexed over one TCP port.
+  WS upgrades match path `/ws`; all other requests route to HTTP.
+
+## Routes
+
+| Path                | Method     | Purpose                                         |
+| ------------------- | ---------- | ----------------------------------------------- |
+| `/ws`               | GET/UPGRADE| Authenticated peer connections (WebSocket)      |
+| `/hook/set-status`  | POST       | Claude Code hook scripts report peer status     |
+| `/health`           | GET        | Liveness + build info. 503 if Postgres is down. |
+| `/metrics`          | GET        | Prometheus plaintext metrics                    |
+
+## Environment variables
+
+### Required
+
+| Var            | Format                                    | Notes                        |
+| -------------- | ----------------------------------------- | ---------------------------- |
+| `DATABASE_URL` | `postgres://user:pass@host:port/db`       | Must use postgres:// scheme  |
+
+### Optional (with defaults)
+
+| Var                         | Default | Range              | Purpose                                              |
+| --------------------------- | ------- | ------------------ | ---------------------------------------------------- |
+| `BROKER_PORT`               | `7900`  | any free port      | Single port for HTTP + WS                            |
+| `STATUS_TTL_SECONDS`        | `60`    | > 0                | Flip stuck "working" peers to idle after this TTL    |
+| `HOOK_FRESH_WINDOW_SECONDS` | `30`    | > 0                | Window during which a hook signal beats JSONL infer  |
+| `MAX_CONNECTIONS_PER_MESH`  | `100`   | > 0                | Refuse new WS at capacity with close code 1008       |
+| `MAX_MESSAGE_BYTES`         | `65536` | > 0                | Max WS payload and hook POST body size               |
+| `HOOK_RATE_LIMIT_PER_MIN`   | `30`    | > 0                | Per-(pid,cwd) token bucket on /hook/set-status       |
+| `NODE_ENV`                  | `development` | dev/prod/test | Standard                                            |
+| `GIT_SHA`                   | —       | hex string         | Preferred over `git rev-parse` fallback, for image builds |
+
+No secrets baked into the image — everything via env at runtime.
+
+## Healthcheck
+
+Container healthcheck SHOULD hit `/health`:
+
+```dockerfile
+HEALTHCHECK --interval=15s --timeout=5s --start-period=10s --retries=3 \
+  CMD bun -e "fetch('http://localhost:7900/health').then(r=>{process.exit(r.ok?0:1)}).catch(()=>process.exit(1))"
+```
+
+`/health` returns `200` with:
+```json
+{
+  "status": "ok",
+  "db": "up",
+  "version": "0.1.0",
+  "gitSha": "84e14ff",
+  "uptime": 123
+}
+```
+
+Returns `503` when Postgres is unreachable (`"status":"degraded","db":"down"`).
+The broker does NOT exit on transient DB failures — it keeps serving
+and recovers automatically when the DB comes back.
+
+## Signals
+
+- `SIGTERM` and `SIGINT` → graceful shutdown:
+  1. Stop background sweepers (TTL, pending-status, DB ping).
+  2. Close all WS connections with code `1001`.
+  3. Mark all active presences as `disconnectedAt=now` in Postgres.
+  4. Close HTTP server.
+  5. Exit 0.
+
+Grace period: ~5s typical. Orchestrators should allow ≥10s before
+sending SIGKILL.
+
+## Image
+
+- **Base**: `oven/bun:1.2-slim` for runtime (Bun executes TS directly).
+  pnpm-install stage can use a separate `node:22-slim` image.
+- **User**: non-root. `oven/bun` ships with UID 1000 `bun` user.
+- **Target size**: <200MB compressed.
+- **Volumes**: none. Broker is stateless.
+
+### Build stages (recommended)
+
+1. **deps**: Node + pnpm + full workspace → `pnpm install --frozen-lockfile --ignore-scripts`
+2. **runtime**: Bun + copy node_modules + copy only needed workspace packages:
+   - `apps/broker/`
+   - `packages/db/`
+   - `packages/shared/`
+   - `tooling/typescript/`
+   - root metadata (`package.json`, `pnpm-workspace.yaml`, `pnpm-lock.yaml`, `tsconfig.json`)
+
+### Build args
+
+- `GIT_SHA` SHOULD be passed at build time and forwarded as ENV so
+  `/health` surfaces the image commit:
+  ```dockerfile
+  ARG GIT_SHA
+  ENV GIT_SHA=$GIT_SHA
+  ```
+  CI should set `--build-arg GIT_SHA=${GITHUB_SHA:0:7}` (or equivalent).
+
+## Dependencies
+
+Runtime needs reachable:
+- **Postgres 15+** with `pgvector` extension enabled (the broker itself
+  doesn't use vector, but shared migrations do — if you deploy the
+  broker-only migration subset you can drop pgvector).
+- No other external services. No Redis, no queue, no cache.
+
+## Deployment targets (authoritative lane)
+
+- **Production**: OVH VPS via Coolify, Traefik-fronted. Internal port
+  7900 → Traefik → `ic.claudemesh.com:443`. Separate deploy lane owns
+  Traefik labels, TLS, DNS, compose.
+- **Test DB on CI**: spin up pgvector/pgvector:pg17, create
+  `claudemesh_test` database, run migrations, then `pnpm test` in
+  `apps/broker`. See below.
+
+## CI integration
+
+Test suite requires a live Postgres. Suggested GitHub Actions step:
+
+```yaml
+services:
+  postgres:
+    image: pgvector/pgvector:pg17
+    env:
+      POSTGRES_USER: turbostarter
+      POSTGRES_PASSWORD: turbostarter
+      POSTGRES_DB: claudemesh_test
+    ports: ['5440:5432']
+    options: >-
+      --health-cmd="pg_isready -U turbostarter"
+      --health-interval=5s
+
+steps:
+  - uses: actions/checkout@v4
+  - run: pnpm install --frozen-lockfile
+  - run: cd packages/db && pnpm exec drizzle-kit migrate
+    env: { DATABASE_URL: 'postgresql://turbostarter:turbostarter@127.0.0.1:5440/claudemesh_test' }
+  - run: cd apps/broker && pnpm test
+    env: { DATABASE_URL: 'postgresql://turbostarter:turbostarter@127.0.0.1:5440/claudemesh_test' }
+```
+
+## Metrics
+
+Scraped by Prometheus via `GET /metrics`. Key series:
+
+- `broker_connections_active` (gauge)
+- `broker_connections_total` (counter)
+- `broker_connections_rejected_total{reason}` (counter: capacity, unauthorized)
+- `broker_messages_routed_total{priority}` (counter: now, next, low)
+- `broker_messages_rejected_total{reason}` (counter)
+- `broker_queue_depth` (gauge — undelivered messages)
+- `broker_ttl_sweeps_total{flipped}` (counter)
+- `broker_hook_requests_total` (counter)
+- `broker_hook_requests_rate_limited_total` (counter)
+- `broker_db_healthy` (gauge: 0 or 1)
+
+Alert recommendations:
+- `broker_db_healthy == 0` for > 60s → page oncall
+- `broker_queue_depth > 10000` → investigate
+- `broker_connections_rejected_total{reason="capacity"}` rising → scale
+
+## Logs
+
+Structured JSON, one line per event, stderr. No log aggregation
+required — suitable for stdout/stderr capture and direct ingestion
+into Loki/Datadog/CloudWatch without parsing.

+# 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
+
+```sh
+# 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:
+
+```sh
+claudemesh install
+# prints:  claude mcp add claudemesh --scope user -- claudemesh mcp
+```
+
+Run the printed command, then restart Claude Code.
+
+## Join a mesh
+
+```sh
+claudemesh join https://claudemesh.com/join/<token>
+```
+
+## Launch Claude Code
+
+For real-time **push messages** from peers (messages injected mid-turn
+as `<channel source="claudemesh">` system reminders), launch with:
+
+```sh
+claudemesh launch
+# or pass through any claude flags:
+claudemesh launch --model opus
+claudemesh launch --resume
+```
+
+Under the hood this runs:
+
+```sh
+claude --dangerously-load-development-channels server:claudemesh
+```
+
+Plain `claude` still works — the MCP tools are available — but incoming
+messages are **pull-only** via the `check_messages` tool instead of
+being pushed to Claude immediately.
+
+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
+
+```sh
+claudemesh install         # register MCP + status hooks
+claudemesh uninstall       # remove MCP + status hooks
+claudemesh launch [args]   # launch Claude Code with push messages enabled
+claudemesh join <url>      # join a mesh via invite URL
+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.

+- list_peers: see joined meshes + their connection status
+- send_message: send to a peer by display name, pubkey, #channel, or * broadcast (priority: now/next/low)
+- check_messages: drain buffered inbound messages (usually auto-pushed)
+- set_summary: 1-2 sentence summary of what you're working on
+- set_status: manually override your status (idle/working/dnd)
+
+Message priority:
+- "now": delivered immediately regardless of recipient status (use sparingly)
+- "next" (default): delivered when recipient is idle
+- "low": pull-only (check_messages)
+
+If you have multiple joined meshes, prefix the \`to\` argument of send_message with \`<mesh-slug>:\` to disambiguate. Otherwise claudemesh picks the single joined mesh.`,
