Add multi-address fallback for node connectivity

NodeConfig and MasterNodeConfig gain an optional addresses[] field
for fallback addresses tried in order after the primary address.
Provides resilience when Tailscale DNS is down or a node is only
reachable via LAN.

- dialAgentMulti: tries each address with a 3s health check, returns
  first success
- forEachNode: uses multi-address dialing
- AgentPool.AddNodeMulti: master tries all addresses when connecting
- AllAddresses(): deduplicates primary + fallback addresses

Config example:
  [[nodes]]
  name = "rift"
  address = "rift.scylla-hammerhead.ts.net:9444"
  addresses = ["100.95.252.120:9444", "192.168.88.181:9444"]

Existing configs without addresses[] work unchanged.

+

+| 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.

+  `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.

 - **Generated by converting from mcdeploy.toml** during initial MCP

+### Build Configuration
+
+Service definitions include a `[build]` section that tells MCP how to
+build container images from source. This replaces the standalone
+`mcdeploy.toml` -- MCP owns the full build-push-deploy lifecycle.
+
+Top-level build fields:
+
+| Field | Purpose |
+|-------|---------|
+| `path` | Source directory relative to the workspace root |
+| `build.uses_mcdsl` | Whether the mcdsl module is needed at build time |
+| `build.images.<name>` | Maps each image name to its Dockerfile path |
+
+The workspace root is configured in `~/.config/mcp/mcp.toml`:
+
+```toml
+[build]
+workspace = "~/src/metacircular"
+```
+
+A service with `path = "mcr"` resolves to `~/src/metacircular/mcr`. The
+convention assumes `~/src/metacircular/<path>` on operator workstations
+(vade, orion). The workspace path can be overridden but the convention
+should hold for all standard machines.
+
+### Build and Release Workflow
+
+The standard release workflow for a service:
+
+1. **Tag** the release in git (`git tag -a v1.1.0`).
+2. **Build** the images: `mcp build <service>` reads the service
+   definition, locates the source tree via `path`, and runs `docker
+   build` using each Dockerfile in `[build.images]`. Images are tagged
+   with the version from the component `image` field and pushed to MCR.
+3. **Update** the service definition: bump the version tag in each
+   component's `image` field.
+4. **Deploy**: `mcp sync` or `mcp deploy <service>`.
+
+#### `mcp build` Resolution
+
+`mcp build <service>` does the following:
+
+1. Read the service definition to find `[build.images]` and `path`.
+2. Resolve the source tree: `<workspace>/<path>`.
+3. For each image in `[build.images]`:
+   a. Build with the Dockerfile at `<source>/<dockerfile>`.
+   b. If `uses_mcdsl = true`, include the mcdsl directory in the build
+      context (or use a multi-module build strategy).
+   c. Tag as `<registry>/<image>:<version>` (version extracted from the
+      matching component's `image` field).
+   d. Push to MCR.
+
+#### `mcp sync` Auto-Build
+
+`mcp sync` pushes service definitions to agents. Before deploying, it
+checks that each component's image tag exists in the registry:
+
+- **Tag exists** → proceed with deploy.
+- **Tag missing, source tree available** → build and push automatically,
+  then deploy.
+- **Tag missing, no source tree** → fail with error:
+  `"mcr:v1.1.0 not found in registry and no source tree at ~/src/metacircular/mcr"`.
+
+This ensures `mcp sync` is a single command for the common case (tag,
+update version, sync) while failing clearly when the build environment
+is not available.
+
+#### Image Versioning
+
+Service definitions MUST pin explicit version tags (e.g., `v1.1.0`),
+never `:latest`. This ensures:
+
+- `mcp status` shows the actual running version.
+- Deployments are reproducible.
+- Rollbacks are explicit (change the tag back to the previous version).

+

 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.

-The agent runs as a systemd service. Container-first deployment is a v2
+On **NixOS** (rift), provisioning is declarative via the NixOS config.
-concern -- MCP needs to be running before it can manage its own agent.
+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.

+
+MCR (container registry) and MCNS (DNS) are both deployed as containers
+via MCP, but MCP itself depends on them:
+
+- **MCR** is reachable through mc-proxy (L4 passthrough on `:8443`).
+  The agent pulls images from MCR during `mcp deploy`.
+- **MCNS** serves DNS for internal zones. Tailscale and the overlay

+
+This creates circular dependencies during cold-start or recovery:
+
+```
+mcp deploy → agent pulls image → needs MCR → needs mc-proxy
+mcp deploy → agent dials MCR → DNS resolves hostname → needs MCNS
+```
+
+**Cold-start procedure** (no containers running):
+
+1. **Build images on the operator workstation** for mc-proxy, MCR, and
+   MCNS. Transfer to rift via `podman save` / `scp` / `podman load`
+   since the registry is not yet available:
+   ```
+   docker save <image> -o /tmp/image.tar
+   scp /tmp/image.tar <rift-lan-ip>:/tmp/
+   # on rift, as mcp user:
+   podman load -i /tmp/image.tar
+   ```
+   Use the LAN IP for scp, not a DNS name (DNS is not running yet).
+
+2. **Start MCNS first** (DNS must come up before anything that resolves
+   hostnames). Run directly with podman since the MCP agent cannot reach
+   the registry yet:
+   ```
+   podman run -d --name mcns --restart unless-stopped \

+4. **Start MCR** (API server, then web UI):
+   ```
+   podman run -d --name mcr-api --network mcpnet \
+     --restart unless-stopped \
+     -p 127.0.0.1:28443:8443 -p 127.0.0.1:29443:9443 \
+     -v /srv/mcr:/srv/mcr \
+     <mcr-image> server --config /srv/mcr/mcr.toml
+   ```
+
+5. **Push images to MCR** from the operator workstation now that the
+   registry is reachable:
+   ```
+   docker push <registry>/<image>:<tag>
+   ```
+
+6. **Start the MCP agent** (systemd service). It can now reach MCR for
+   image pulls.
+
+7. **`mcp adopt`** the manually-started containers to bring them under
+   MCP management. Then `mcp service export` to generate service
+   definition files.
+
+From this point, `mcp deploy` works normally. The manually-started
+containers are replaced by MCP-managed ones on the next deploy.
+
+**Recovery procedure** (mc-proxy or MCNS crashed):
+
+If mc-proxy or MCNS goes down, the agent cannot pull images (registry
+unreachable or DNS broken). Recovery:
+
+1. Check if the required image is cached locally:
+   `podman images | grep <service>`
+2. If cached, start the container directly with `podman run` (same
+   flags as the cold-start procedure above).
+3. If not cached, transfer the image from the operator workstation via
+   `podman save` / `scp` / `podman load` using the LAN IP.
+4. Once the infrastructure service is running, `mcp deploy` resumes
+   normal operation for other services.

+## Registry Cleanup: Purge
+
+### Problem
+
+The agent's registry accumulates stale entries over time. A component
+that was replaced (e.g., `mcns/coredns` → `mcns/mcns`) or a service
+that was decommissioned remains in the registry indefinitely with
+`observed=removed` or `observed=unknown`. There is no mechanism to tell
+the agent "this component no longer exists and should not be tracked."
+
+This causes:
+- Perpetual drift alerts for components that will never return.
+- Noise in `mcp status` and `mcp list` output.
+- Confusion about what the agent is actually responsible for.
+
+The existing `mcp sync` compares local service definitions against the
+agent's registry and updates desired state for components that are
+defined. But it does not remove components or services that are *absent*
+from the local definitions — sync is additive, not declarative.
+
+### Design: `mcp purge`
+
+Purge removes registry entries that are both **unwanted** (not in any
+current service definition) and **gone** (no corresponding container in
+the runtime). It is the garbage collector for the registry.
+
+```
+mcp purge [--dry-run]               Purge all stale entries
+mcp purge <service> [--dry-run]     Purge stale entries for one service
+mcp purge <service>/<component> [--dry-run]  Purge a specific component
+```
+
+#### Semantics
+
+Purge operates on the agent's registry, not on containers. It never
+stops or removes running containers. The rules:
+
+1. **Component purge**: a component is eligible for purge when:
+   - Its observed state is `removed`, `unknown`, or `exited`, AND
+   - It is not present in any current service definition file
+     (i.e., `mcp sync` would not recreate it).
+
+   Purging a component deletes its registry entry (from `components`,
+   `component_ports`, `component_volumes`, `component_cmd`) and its
+   event history.
+
+2. **Service purge**: a service is eligible for purge when all of its
+   components have been purged (or it has no components). Purging a
+   service deletes its `services` row.
+
+3. **Safety**: purge refuses to remove a component whose observed state
+   is `running` or `stopped` (i.e., a container still exists in the
+   runtime). This prevents accidentally losing track of live containers.
+   The operator must `mcp stop` and wait for the container to be removed
+   before purging, or manually remove it via podman.
+
+4. **Dry run**: `--dry-run` lists what would be purged without modifying
+   the registry. This is the default-safe way to preview the operation.
+
+#### Interaction with Sync
+
+`mcp sync` pushes desired state from service definitions. `mcp purge`
+removes entries that sync would never touch. They are complementary:
+
+- `sync` answers: "what should exist?" (additive)
+- `purge` answers: "what should be forgotten?" (subtractive)
+
+A full cleanup is: `mcp sync && mcp purge`.
+
+An alternative design would make `mcp sync` itself remove entries not
+present in service definitions (fully declarative sync). This was
+rejected because:
+
+- Sync currently only operates on services that have local definition
+  files. A service without a local file is left untouched — this is
+  desirable when multiple operators or workstations manage different
+  services.
+- Making sync destructive increases the blast radius of a missing file
+  (accidentally deleting the local `mcr.toml` would cause sync to
+  purge MCR from the registry).
+- Purge as a separate, explicit command with `--dry-run` gives the
+  operator clear control over what gets cleaned up.
+
+#### Agent RPC
+
+```protobuf
+rpc PurgeComponent(PurgeRequest) returns (PurgeResponse);
+
+message PurgeRequest {
+  string service = 1;       // service name (empty = all services)
+  string component = 2;     // component name (empty = all eligible in service)
+  bool dry_run = 3;         // preview only, do not modify registry
+}
+
+message PurgeResponse {
+  repeated PurgeResult results = 1;
+}
+
+message PurgeResult {
+  string service = 1;
+  string component = 2;
+  bool purged = 3;           // true if removed (or would be, in dry-run)
+  string reason = 4;         // why eligible, or why refused
+}
+```
+
+The CLI sends the set of currently-defined service/component names
+alongside the purge request so the agent can determine what is "not in
+any current service definition" without needing access to the CLI's
+filesystem.
+
+#### Example
+
+After replacing `mcns/coredns` with `mcns/mcns`:
+
+```
+$ mcp purge --dry-run
+would purge mcns/coredns (observed=removed, not in service definitions)
+
+$ mcp purge
+purged mcns/coredns
+
+$ mcp status
+SERVICE    COMPONENT  DESIRED  OBSERVED  VERSION
+mc-proxy   mc-proxy   running  running   latest
+mcns       mcns       running  running   v1.0.0
+mcr        api        running  running   latest
+mcr        web        running  running   latest
+metacrypt  api        running  running   latest
+metacrypt  web        running  running   latest
+```
+
+#### Registry Auth
+
+Purge also cleans up after the `mcp adopt` workflow. When containers are
+adopted and later removed (replaced by a proper deploy), the adopted
+entries linger. Purge removes them once the containers are gone and the
+service definition no longer references them.

+MCP v2 extends the single-node agent model to a multi-node fleet with a central master process. See the root repo's `docs/phase-e-plan.md` and `docs/architecture-v2.md` for the full design.

+- **svc** is operational as an edge node (manages mc-proxy routing only, no containers)

+**Key v2 concepts (in development):**
+- **mcp-master** — central orchestrator on rift. Accepts CLI commands, dispatches to agents, maintains node registry, coordinates edge routing.
+- **Agent self-registration** — agents register with the master on startup (name, role, address, arch). No static node config required after bootstrap.
+- **Tier-based placement** — `tier = "core"` runs on the master node, `tier = "worker"` (default) is auto-placed on a worker with capacity, `node = "<name>"` overrides for pinned services.
+- **Edge routing** — `public = true` on routes declares intent; the master assigns the route to an edge node (currently svc).

+- Agent needs `PATH`, `HOME`, `XDG_RUNTIME_DIR` in systemd environment
+
+## Platform Evolution (see PLATFORM_EVOLUTION.md)
+
+### Phase A — COMPLETE (2026-03-27)
+
+- [x] Route declarations in service definitions (`[[components.routes]]`)
+- [x] Automatic port allocation by agent (10000-60000, mutex-serialized)
+- [x] `$PORT` / `$PORT_<NAME>` env var injection into containers
+- [x] Proto: `RouteSpec` message, `routes` + `env` on `ComponentSpec`
+- [x] Registry: `component_routes` table with `host_port` tracking
+- [x] Backward compatible: old-style `ports` strings still work
+
+### Phase B — COMPLETE (2026-03-27)
+
+- [x] Agent connects to mc-proxy via Unix socket on deploy
+- [x] Agent calls `AddRoute` to register routes with mc-proxy
+- [x] Agent calls `RemoveRoute` on service stop/teardown
+- [x] Agent config: `[mcproxy] socket` and `cert_dir` fields
+- [x] TLS certs: pre-provisioned at convention path (Phase C automates)
+- [x] Nil-safe: if socket not configured, route registration silently skipped
+
+## Remaining Work
+
+### Operational — Next Priority
+
+- [ ] **MCR auth for mcp user** — podman pull from MCR requires OCI token
+  auth. Currently using image save/load workaround. Need either: OCI token
+  flow support in the agent, or podman login with service account credentials.
+- [ ] **Vade DNS routing** — Tailscale MagicDNS intercepts `*.svc.mcp.metacircular.net`
+  queries on vade, preventing hostname-based TLS connections. CLI currently
+  uses IP address directly. Fix: Tailscale DNS configuration or split-horizon
+  setup on vade.
+- [ ] **Service export completeness** — `mcp service export` only captures
+  name + image from the registry. Should include full spec (network, ports,
+  volumes, user, restart, cmd). Requires the agent's `ListServices` response
+  to include full `ComponentSpec` data, not just `ComponentInfo`.
+
+### Quality
+
+- [ ] **P5.1** Integration test suite — end-to-end CLI → agent → podman tests
+- [ ] **P5.2** Bootstrap procedure test — documented and verified
+- [ ] **README.md** — quick-start guide
+- [ ] **RUNBOOK.md** — operational procedures (unseal metacrypt, restart
+  services, disaster recovery)
+
+### Design
+
+- [ ] **Self-management** — how MCP updates mc-proxy and its own agent without
+  circular dependency. Likely answer: NixOS manages the agent and mc-proxy
+  binaries; MCP manages their containers. Or: staged restart with health
+  checks.
+- [ ] **ARCHITECTURE.md proto naming** — update spec to match buf-lint-compliant
+  message names (StopServiceRequest vs ServiceRequest, AdoptContainers vs
+  AdoptContainer).
+- [ ] **mcdsl DefaultPath helper** — `DefaultPath(name) string` for consistent
+  config file discovery across all services. Root: /srv, /etc. User: XDG, /srv.
+- [ ] **Engineering standards update** — document REST+gRPC parity exception
+  for infrastructure services (MCP agent).
+
+### Infrastructure
+
+- [ ] **Certificate renewal** — MCP-managed cert renewal before expiry.
+  Agent cert expires 2026-06-24. Need automated renewal via Metacrypt ACME
+  or REST API.
+- [ ] **Monitor alerting** — configure alert_command on rift (ntfy, webhook,
+  or custom script) for drift/flap notifications.
+- [ ] **Backup timer** — install mcp-agent-backup timer via NixOS config.
+
+## Current State (2026-03-26)
+
+MCP is deployed and operational on rift. The agent runs as a systemd service
+under the `mcp` user with rootless podman. All platform services (metacrypt,
+mc-proxy, mcr, mcns) are managed by MCP with complete service definitions.

+# MCP — Metacircular Control Plane
+
+MCP is the orchestrator for the [Metacircular](https://metacircular.net)
+platform. It manages container lifecycle, tracks what services run where,
+and transfers files between the operator's workstation and managed nodes.
+
+## Architecture
+
+**CLI** (`mcp`) — thin client on the operator's workstation. Reads local
+service definition files, pushes intent to agents, queries status.
+
+**Agent** (`mcp-agent`) — per-node daemon. Manages containers via rootless
+podman, stores a SQLite registry of desired/observed state, monitors for
+drift, and alerts the operator.
+
+## Quick Start
+
+### Build
+
+```bash
+make all          # vet, lint, test, build
+make mcp          # CLI only
+make mcp-agent    # agent only
+```
+
+### Install the CLI
+
+```bash
+cp mcp ~/.local/bin/
+mkdir -p ~/.config/mcp/services
+```
+
+Create `~/.config/mcp/mcp.toml`:
+
+```toml
+[services]
+dir = "/home/<user>/.config/mcp/services"

+
+[[nodes]]
+name = "rift"
+address = "100.95.252.120:9444"
+```
+
+### Authenticate
+
+```bash
+mcp login
+```
+
+### Check status
+
+```bash
+mcp status    # full picture: services, drift, events
+mcp ps        # live container check with uptime
+mcp list      # quick registry query
+```
+
+### Deploy a service
+
+Write a service definition in `~/.config/mcp/services/<name>.toml`:
+
+```toml
+name = "myservice"
+node = "rift"
+active = true
+
+[[components]]
+name = "api"
+image = "mcr.svc.mcp.metacircular.net:8443/myservice:v1.0.0"
+network = "mcpnet"
+user = "0:0"
+restart = "unless-stopped"
+ports = ["127.0.0.1:8443:8443"]
+volumes = ["/srv/myservice:/srv/myservice"]
+cmd = ["server", "--config", "/srv/myservice/myservice.toml"]
+```
+

+Operational procedures for the Metacircular Control Plane. Written for
+operators at 3 AM.
+
+## Service Overview
+
+MCP manages container lifecycle on Metacircular nodes. Two components:
+- **mcp-agent** — systemd service on each node (rift). Manages containers
+  via rootless podman, stores registry in SQLite, monitors for drift.
+- **mcp** — CLI on the operator's workstation (vade). Pushes desired state,
+  queries status.
+
+## Health Checks
+
+### Quick status
+
+```bash
+mcp status
+```
+
+Shows all services, desired vs observed state, drift, and recent events.
+No drift = healthy.
+
+### Agent process
+
+```bash
+ssh rift "doas systemctl status mcp-agent"
+ssh rift "doas journalctl -u mcp-agent --since '10 min ago' --no-pager"
+```
+
+### Individual service
+
+```bash
+mcp status metacrypt
+```
+
+## Common Operations
+
+### Check what's running
+
+```bash
+mcp ps          # live check with uptime
+mcp list        # from registry (no runtime query)
+mcp status      # full picture with drift and events
+```
+
+### Restart a service
+
+```bash
+mcp restart metacrypt
+```
+
+Restarts all components. Does not change the `active` flag. Metacrypt
+will need to be unsealed after restart.
+
+### Stop a service
+
+```bash
+mcp stop metacrypt
+```
+
+Sets `active = false` in the service definition file and stops all
+containers. The agent will not restart them.
+
+### Start a stopped service
+
+```bash
+mcp start metacrypt
+```
+
+Sets `active = true` and starts all containers.
+
+### Deploy an update
+
+Edit the service definition to update the image tag, then deploy:
+
+```bash
+mcp service edit metacrypt    # opens in $EDITOR
+mcp deploy metacrypt          # deploys all components
+mcp deploy metacrypt/web      # deploy just the web component
+```
+
+### Push a config file to a node
+
+```bash
+mcp push metacrypt.toml metacrypt               # → /srv/metacrypt/metacrypt.toml
+mcp push cert.pem metacrypt certs/cert.pem      # → /srv/metacrypt/certs/cert.pem
+```
+
+### Pull a file from a node
+
+```bash
+mcp pull metacrypt metacrypt.toml ./local-copy.toml
+```
+
+### Sync desired state
+
+Push all service definitions to the agent without deploying:
+
+```bash
+mcp sync
+```
+
+### View service definition
+
+```bash
+mcp service show metacrypt    # from agent registry
+cat ~/.config/mcp/services/metacrypt.toml  # local file
+```
+
+### Export service definition from agent
+
+```bash
+mcp service export metacrypt
+```
+
+Writes the agent's current spec to the local service definition file.
+
+## Unsealing Metacrypt
+
+Metacrypt starts sealed after any restart. Unseal via the API:
+
+```bash
+curl -sk -X POST https://metacrypt.svc.mcp.metacircular.net:8443/v1/unseal \
+  -H "Content-Type: application/json" \
+  -d '{"password":"<unseal-password>"}'
+```
+
+Or via the web UI at `https://metacrypt.svc.mcp.metacircular.net`.
+
+**Important:** Restarting metacrypt-api requires unsealing. To avoid this
+when updating just the UI, deploy only the web component:
+
+```bash
+mcp deploy metacrypt/web
+```
+
+## Agent Management
+
+### Restart the agent
+
+```bash
+ssh rift "doas systemctl restart mcp-agent"
+```
+
+Containers keep running — the agent is stateless w.r.t. container
+lifecycle. Podman's restart policy keeps containers up.
+
+### View agent logs
+
+```bash
+ssh rift "doas journalctl -u mcp-agent -f"            # follow
+ssh rift "doas journalctl -u mcp-agent --since today"  # today's logs
+```
+
+### Agent database backup
+
+```bash
+ssh rift "doas -u mcp /usr/local/bin/mcp-agent snapshot --config /srv/mcp/mcp-agent.toml"
+```
+
+Backups go to `/srv/mcp/backups/`.
+
+### Update the agent binary
+
+```bash
+# On vade, in the mcp repo:
+make clean && make mcp-agent
+scp mcp-agent rift:/tmp/
+ssh rift "doas systemctl stop mcp-agent && \
+  doas cp /tmp/mcp-agent /usr/local/bin/mcp-agent && \
+  doas systemctl start mcp-agent"
+```
+
+### Update the CLI binary
+
+```bash
+make clean && make mcp
+cp mcp ~/.local/bin/
+```
+
+## Node Management
+
+### List nodes
+
+```bash
+mcp node list
+```
+
+### Add a node
+
+```bash
+mcp node add <name> <address:port>
+```
+
+### Remove a node
+
+```bash
+mcp node remove <name>
+```
+
+## TLS Certificate Renewal
+
+The agent's TLS cert is at `/srv/mcp/certs/cert.pem`. Check expiry:
+
+```bash
+ssh rift "openssl x509 -in /srv/mcp/certs/cert.pem -noout -enddate"
+```
+
+To renew (requires a Metacrypt token):
+
+```bash
+export METACRYPT_TOKEN="<token>"
+ssh rift "curl -sk -X POST https://127.0.0.1:18443/v1/engine/request \
+  -H 'Content-Type: application/json' \
+  -H 'Authorization: Bearer $METACRYPT_TOKEN' \
+  -d '{
+    \"mount\": \"pki\",
+    \"operation\": \"issue\",
+    \"path\": \"web\",
+    \"data\": {
+      \"issuer\": \"web\",
+      \"common_name\": \"mcp-agent.svc.mcp.metacircular.net\",
+      \"profile\": \"server\",
+      \"dns_names\": [\"mcp-agent.svc.mcp.metacircular.net\"],
+      \"ip_addresses\": [\"100.95.252.120\", \"192.168.88.181\"],
+      \"ttl\": \"2160h\"
+    }
+  }'" > /tmp/cert-response.json
+
+# Extract and install cert+key from the JSON response, then:
+ssh rift "doas systemctl restart mcp-agent"
+```
+
+## Incident Procedures
+
+### Service not running (drift detected)
+
+1. `mcp status` — identify which service/component drifted.
+2. Check agent logs: `ssh rift "doas journalctl -u mcp-agent --since '10 min ago'"`
+3. Check container logs: `ssh rift "doas -u mcp podman logs <container-name>"`
+4. Restart: `mcp restart <service>`
+5. If metacrypt: unseal after restart.
+
+### Agent unreachable
+
+1. Check if the agent process is running: `ssh rift "doas systemctl status mcp-agent"`
+2. If stopped: `ssh rift "doas systemctl start mcp-agent"`
+3. Check logs for crash reason: `ssh rift "doas journalctl -u mcp-agent -n 50"`
+4. Containers keep running independently — podman's restart policy handles them.
+
+### Token expired
+
+MCP CLI shows `UNAUTHENTICATED` or `PERMISSION_DENIED`:
+
+1. Check token: the mcp-agent service account token is at `~/.config/mcp/token`
+2. Validate: `curl -sk -X POST -H "Authorization: Bearer $(cat ~/.config/mcp/token)" https://mcias.metacircular.net:8443/v1/token/validate`
+3. If expired: generate a new service account token from MCIAS admin dashboard.
+
+### Database corruption
+
+The agent's SQLite database is at `/srv/mcp/mcp.db`:
+
+1. Stop the agent: `ssh rift "doas systemctl stop mcp-agent"`
+2. Restore from backup: `ssh rift "doas -u mcp cp /srv/mcp/backups/<latest>.db /srv/mcp/mcp.db"`
+3. Start the agent: `ssh rift "doas systemctl start mcp-agent"`
+4. Run `mcp sync` to re-push desired state.
+
+If no backup exists, delete the database and re-bootstrap:
+
+1. `ssh rift "doas -u mcp rm /srv/mcp/mcp.db"`
+2. `ssh rift "doas systemctl start mcp-agent"` (creates fresh database)
+3. `mcp sync` (pushes all service definitions)
+
+### Disaster recovery (rift lost)
+
+1. Provision new machine, connect to overlay network.
+2. Apply NixOS config (creates mcp user, installs agent).
+3. Install mcp-agent binary.
+4. Restore `/srv/` from backups (each service's backup timer creates daily snapshots).
+5. Provision TLS cert from Metacrypt.
+6. Start agent: `doas systemctl start mcp-agent`
+7. `mcp sync` from vade to push service definitions.
+8. Unseal Metacrypt.
+

+# MCP Bootstrap Procedure
+
+How to bring MCP up on a node for the first time, including migrating
+existing containers from another user's podman instance.
+
+## Prerequisites
+
+- NixOS configuration applied with `configs/mcp.nix` (creates `mcp` user
+  with rootless podman, subuid/subgid, systemd service)
+- MCIAS system account with `admin` role (for token validation and cert
+  provisioning)
+- Metacrypt running (for TLS certificate issuance)
+
+## Step 1: Provision TLS Certificate
+
+Issue a cert from Metacrypt with DNS and IP SANs:
+
+```bash
+export METACRYPT_TOKEN="<admin-token>"
+
+# From a machine that can reach Metacrypt (e.g., via loopback on rift):
+curl -sk -X POST https://127.0.0.1:18443/v1/engine/request \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $METACRYPT_TOKEN" \

+doas chmod 600 /srv/mcp/certs/cert.pem /srv/mcp/certs/key.pem
+```
+
+## Step 2: Add DNS Record
+
+Add an A record for `mcp-agent.svc.mcp.metacircular.net` pointing to the
+node's IP in the MCNS zone file, bump the serial, restart CoreDNS.
+
+## Step 3: Write Agent Config
+
+Create `/srv/mcp/mcp-agent.toml`:
+
+```toml
+[server]
+grpc_addr = "<tailscale-ip>:9444"
+tls_cert  = "/srv/mcp/certs/cert.pem"
+tls_key   = "/srv/mcp/certs/key.pem"
+
+[database]
+path = "/srv/mcp/mcp.db"
+
+[mcias]
+server_url   = "https://mcias.metacircular.net:8443"
+service_name = "mcp-agent"
+
+[agent]
+node_name         = "<node-name>"
+container_runtime = "podman"
+
+[monitor]
+interval       = "60s"
+alert_command  = []
+cooldown       = "15m"
+flap_threshold = 3
+flap_window    = "10m"
+retention      = "30d"
+
+[log]
+level = "info"
+```
+
+## Step 4: Install Agent Binary
+
+```bash
+scp mcp-agent <node>:/tmp/
+ssh <node> "doas cp /tmp/mcp-agent /usr/local/bin/mcp-agent"
+```
+
+## Step 5: Start the Agent
+
+```bash
+ssh <node> "doas systemctl start mcp-agent"
+ssh <node> "doas systemctl status mcp-agent"
+```
+
+## Step 6: Configure CLI
+
+On the operator's workstation, create `~/.config/mcp/mcp.toml` and save
+the MCIAS admin service account token to `~/.config/mcp/token`.
+
+## Step 7: Migrate Containers (if existing)
+
+If containers are running under another user (e.g., `kyle`), migrate them
+to the `mcp` user's podman. Process each service in dependency order:
+
+**Dependency order:** Metacrypt → MC-Proxy → MCR → MCNS
+
+For each service:
+
+```bash
+# 1. Stop containers under the old user
+ssh <node> "podman stop <container> && podman rm <container>"
+
+# 2. Transfer ownership of data directory
+ssh <node> "doas chown -R mcp:mcp /srv/<service>"
+
+# 3. Transfer images to mcp's podman
+ssh <node> "podman save <image> -o /tmp/<service>.tar"
+ssh <node> "doas su -l -s /bin/sh mcp -c 'XDG_RUNTIME_DIR=/run/user/<uid> podman load -i /tmp/<service>.tar'"
+
+# 4. Start containers under mcp (with new naming convention)
+ssh <node> "doas su -l -s /bin/sh mcp -c 'XDG_RUNTIME_DIR=/run/user/<uid> podman run -d \
+  --name <service>-<component> \
+  --network mcpnet \
+  --restart unless-stopped \
+  --user 0:0 \
+  -p <ports> \
+  -v /srv/<service>:/srv/<service> \
+  <image> <cmd>'"
+```
+
+**Container naming convention:** `<service>-<component>` (e.g.,
+`metacrypt-api`, `metacrypt-web`, `mc-proxy`).
+
+**Network:** Services whose components need to communicate (metacrypt
+api↔web, mcr api↔web) must be on the same podman network with DNS
+enabled. Create with `podman network create mcpnet`.
+
+**Config updates:** If service configs reference container names for
+inter-component communication (e.g., `vault_grpc = "metacrypt:9443"`),
+update them to use the new names (e.g., `vault_grpc = "metacrypt-api:9443"`).
+
+**Unseal Metacrypt** after migration — it starts sealed.
+
+## Step 8: Adopt Containers
+
+```bash
+mcp adopt metacrypt
+mcp adopt mc-proxy
+mcp adopt mcr
+mcp adopt mcns
+```
+
+## Step 9: Export and Complete Service Definitions
+
+```bash
+mcp service export metacrypt
+mcp service export mc-proxy
+mcp service export mcr
+mcp service export mcns
+```
+
+The exported files will have name + image only. Edit each file to add the
+full container spec: network, ports, volumes, user, restart, cmd.
+
+Then sync to push the complete specs:
+
+```bash
+mcp sync
+```
+
+## Step 10: Verify
+
+```bash
+mcp status
+```
+
+All services should show `desired: running`, `observed: running`, no drift.
+
+## Lessons Learned (from first deployment, 2026-03-26)
+
+- **NixOS systemd sandbox**: `ProtectHome=true` blocks `/run/user` which
+  rootless podman needs. Use `ProtectHome=false`. `ProtectSystem=strict`
+  also blocks it; use `full` instead.
+- **PATH**: the agent's systemd unit needs `PATH=/run/current-system/sw/bin`
+  to find podman.
+- **XDG_RUNTIME_DIR**: must be set to `/run/user/<uid>` for rootless podman.
+  Pin the UID in NixOS config to avoid drift.
+- **Podman ps JSON**: the `Command` field is `[]string`, not `string`.
+- **Container naming**: `mc-proxy` (service with hyphen) breaks naive split
+  on `-`. The agent uses registry-aware splitting.
+- **Token whitespace**: token files with trailing newlines cause gRPC header
+  errors. The CLI trims whitespace.
+- **MCR auth**: rootless podman under a new user can't pull from MCR without
+  OCI token auth. Workaround: `podman save` + `podman load` to transfer
+  images.
