# SQ-009: Server Skeleton

**Status:** `[x] DONE`
**Blocked by:** SQ-008
**Priority:** High

## Description

Running `sq-server` binary with CLI, notmad lifecycle management, health gRPC endpoint, and Axum HTTP health endpoint. Follows the fungus-server pattern exactly.

## Files to Create/Modify

- `crates/sq-server/src/main.rs` - entry point with logging setup
- `crates/sq-server/src/cli.rs` - clap Command enum with Serve subcommand
- `crates/sq-server/src/cli/serve.rs` - ServeCommand with notmad builder
- `crates/sq-server/src/state.rs` - State struct with Config
- `crates/sq-server/src/grpc/mod.rs` - GrpcServer as notmad::Component
- `crates/sq-server/src/grpc/health.rs` - StatusService impl
- `crates/sq-server/src/grpc/error.rs` - gRPC error mapping
- `crates/sq-server/src/servehttp.rs` - Axum health routes

## Configuration

```
SQ_HOST=127.0.0.1:6060          # gRPC listen address
SQ_HTTP_HOST=127.0.0.1:6062     # HTTP listen address
SQ_DATA_DIR=./data               # WAL storage directory
SQ_NODE_ID=node-1                # Unique node identifier
LOG_LEVEL=pretty                 # pretty|json|short
```

## Acceptance Criteria

- [ ] `cargo run -p sq-server -- serve` starts and listens on configured ports
- [ ] gRPC Status RPC returns node_id
- [ ] HTTP GET / returns 200 with health message
- [ ] Graceful shutdown on SIGINT via notmad cancellation token
- [ ] Logging setup matches forest/fungus pattern (pretty/json/short)
