 /**
- * Host-header allowlist middleware for DNS-rebinding protection.
+ * Host-header allowlist middleware (ROADMAP M4.1).
+ *
+ * `createHostCheck` builds a Fastify `onRequest` hook that rejects requests
+ * whose `Host` header is not in the allowlist with a `403 Invalid Host header`
+ * envelope. This is the primary DNS-rebinding defence once the server is
+ * reachable beyond localhost (PLAN §3.4).
+ *
+ * Default-allow set (no configuration required):
+ *   - `localhost`, `*.localhost` (any subdomain of `localhost`);
+ *   - `127.0.0.1`, `::1`, `[::1]`;
+ *   - any literal IP (`net.isIP(host) !== 0`);
+ *   - the host the server actually bound to (`boundHost`);
+ *   - caller-supplied extras (`extra`), where a leading `.` matches the bare
+ *     domain and any subdomain (e.g. `.example.com` matches `example.com` and
+ *     `a.example.com`).
+ *
+ * The default set is intentionally permissive for loopback/IP access so that
+ * `app.inject` (default `Host: localhost:80`) and real `fetch` to
+ * `127.0.0.1:<port>` keep working — existing HTTP/WS tests rely on this.
+ *
+ * 403 responses use the reserved daemon code `40301`
+ * (`packages/protocol/src/error-codes.ts` intentionally omits it; the protocol
+ * package is left untouched). `errEnvelope(code: number, …)` accepts a plain
+ * number, so the literal is passed directly.
