/**
 * The HTTP API.
 *
 * This process holds an unlocked parent seed and binds a TCP port, which is a
 * strictly larger attack surface than the agent's 0600 unix socket. Most of
 * this file is therefore about what the API REFUSES: unauthenticated calls,
 * secret reads on a bearer token alone, path traversal, non-loopback binds,
 * and unbounded unlock guessing. The happy paths matter too, but they are not
 * what makes opening a port defensible.
