The pipe layer of an AI nervous system: one interface connecting provider neurons to your application, across three inference types — generate, stream and decide. `decide` returns typed, calibrated judgements from a non-generative model (~400ms, ~$0.00002

/**
 * Resolve which directories the built-in file tools may touch for a request.
 *
 * Precedence follows the credential pattern: per-call beats instance, and
 * instance beats the `NEUROLINK_TOOL_ROOTS` environment variable. The
 * instance list (or the environment, or the working directory) is a
 * ceiling — per-call roots may only narrow it, so a server that forwards
 * caller options cannot be talked into widening file access.
 *
 * Every root is resolved through realpath once, here, so a root reached
 * through a symlink (`/home/user` → `/home/agent`) admits its own files, and
 * a later `chdir` cannot move the boundary mid-request.
 *
 * @module utils/fileToolRoots

/**
 * The file-tool root policy for one request.
 *
 * Returns `{ roots: null }` when nothing is configured anywhere, which keeps
 * the historical behaviour: the working directory, read at call time.
 *
 * @throws when a root does not exist, is not a directory, or a per-call root
 *   lies outside the instance ceiling. Callers invoke this before any model
 *   request so a misconfiguration fails fast.
