Merge explicit ports with route-allocated ports during deploy

Previously, explicit port mappings from the service definition were
ignored when routes were present. Now both are included, allowing
services to have stable external port bindings alongside dynamic
route-allocated ports.

 ## Authentication and Authorization
 
 MCP follows the platform authentication model: all auth is delegated to

+access control (who can do what).
 
-### Agent Authentication

+
+| Identity | Type | Purpose |
+|----------|------|---------|
+| Human operator (e.g., `kyle`) | human | CLI operations: deploy, stop, start, build |
+| `mcp-agent` | system | Agent-to-service automation: certs, DNS, routes, image pull |
+| Per-service accounts (e.g., `mcq`) | system | Scoped self-management (own DNS records only) |
+| `admin` role | role | MCIAS account management, policy changes, zone creation |
+| `guest` role | role | Explicitly rejected by the agent |
+
+The `admin` role is reserved for MCIAS-level administrative operations
+(account creation, policy management, zone mutations). Routine MCP
+operations (deploy, stop, start, build) do not require admin — any
+authenticated non-guest user or system account is accepted.

+
+### Agent Service Authentication (Agent → Platform Services)
+
+The agent authenticates to platform services using a long-lived system
+account token (`mcp-agent`). Each service has its own token file:
+
+| Service | Token Path | Operations |
+|---------|------------|------------|
+| Metacrypt | `/srv/mcp/metacrypt-token` | TLS cert provisioning (PKI issue) |
+| MCNS | `/srv/mcp/mcns-token` | DNS record create/delete (any name) |
+| mc-proxy | Unix socket (no auth) | Route registration/removal |
+| MCR | podman auth store | Image pull (JWT-as-password) |
+
+These tokens are issued by MCIAS for the `mcp-agent` system account.
+They carry no roles — authorization is handled by each service's policy
+engine:
+
+- **Metacrypt:** Policy rule grants `mcp-agent` write access to
+  `engine/pki/issue`.
+- **MCNS:** Code-level authorization: system account `mcp-agent` can
+  manage any record; other system accounts can only manage records
+  matching their username.
+- **MCR:** Default policy allows all authenticated users to push/pull.
+  MCR accepts MCIAS JWTs as passwords at the `/v2/token` endpoint.

 ### Agent Deployment (on nodes)
 
-The agent is deployed like any other Metacircular service:
+#### Provisioning (one-time per node)
 
-1. Provision the `mcp` system user via NixOS config (with podman access
-   and subuid/subgid ranges for rootless containers).
+Each node needs a one-time setup before the agent can run. The steps are
+the same regardless of OS, but the mechanism differs:
+
+1. Create `mcp` system user with podman access and subuid/subgid ranges.
 2. Set `/srv/` ownership to the `mcp` user (the agent creates and manages
    `/srv/<service>/` directories for all services).
 3. Create `/srv/mcp/` directory and config file.
 4. Provision TLS certificate from Metacrypt.
 5. Create an MCIAS system account for the agent (`mcp-agent`).
-6. Install the `mcp-agent` binary.
-7. Start via systemd unit.
+6. Install the initial `mcp-agent` binary to `/srv/mcp/mcp-agent`.
+7. Install and start the systemd unit.
 
-The agent runs as a systemd service. Container-first deployment is a v2
-concern -- MCP needs to be running before it can manage its own agent.
+On **NixOS** (rift), provisioning is declarative via the NixOS config.
+The NixOS config owns the infrastructure (user, systemd unit, podman,
+directories, permissions) but **not** the binary. `ExecStart` points to
+`/srv/mcp/mcp-agent`, a mutable path that MCP manages. NixOS may
+bootstrap the initial binary there, but subsequent updates come from MCP.
+
+On **Debian** (hyperborea, svc), provisioning is done via a setup script
+or ansible playbook that creates the same layout.
+
+#### Binary Location
+
+The agent binary lives at `/srv/mcp/mcp-agent` on **all** nodes,
+regardless of OS. This unifies the update mechanism across the fleet.
+
+#### Agent Upgrades
+
+After initial provisioning, the agent binary is updated via
+`mcp agent upgrade`. The CLI:
+
+1. Cross-compiles the agent for each target architecture
+   (`GOARCH=amd64` for rift/svc, `GOARCH=arm64` for hyperborea).
+2. SSHs to each node, pushes the binary to `/srv/mcp/mcp-agent.new`.
+3. Atomically swaps the binary (`mv mcp-agent.new mcp-agent`).
+4. Restarts the systemd service (`systemctl restart mcp-agent`).
+
+SSH is used instead of gRPC because:
+- It works even when the agent is broken or has an incompatible version.
+- The binary is ~17MB, which exceeds gRPC default message limits.
+- No self-restart coordination needed.
+
+The CLI uses `golang.org/x/crypto/ssh` for native SSH, keeping the
+entire workflow in a single binary with no external tool dependencies.
+
+#### Node Configuration
+
+Node config includes SSH and architecture info for agent management:
+
+```toml
+[[nodes]]
+name = "rift"
+address = "100.95.252.120:9444"
+ssh = "rift"           # SSH host (from ~/.ssh/config or hostname)
+arch = "amd64"         # GOARCH for cross-compilation
+
+[[nodes]]
+name = "hyperborea"
+address = "100.x.x.x:9444"
+ssh = "hyperborea"
+arch = "arm64"
+```
+
+#### Coordinated Upgrades
+
+New MCP releases often add new RPCs. A CLI at v0.6.0 calling an agent
+at v0.5.0 fails with `Unimplemented`. Therefore agent upgrades must be
+coordinated: `mcp agent upgrade` (with no node argument) upgrades all
+nodes before the CLI is used for other operations.
+
+If a node fails to upgrade, it is reported but the others still proceed.
+The operator can retry or investigate via SSH.
+
+#### Systemd Unit
+
+The systemd unit is the same on all nodes:
