  # Always-on code-execution runner (Jupyter Kernel Gateway). Sessions are
  # in-process kernels, never child containers; the Docker socket is NOT
  # mounted. On an internal-only network — no host port is published, so the
  # runner is reachable only from backend/worker, not from the host/internet.
  # Egress/SSRF blocks, the gVisor `runsc` runtime, and seccomp profile come in
  # the hardening slice.
  #
  # SINGLE TRUST DOMAIN: all sessions share this one container/uid and are
  # isolated by working directory only (per-session cwd) — not by a kernel/OS
  # boundary. The custom kernelspec scrubs secrets from the kernel env, but
  # sibling workspaces are readable under the shared uid and kernels share one
  # address space. Do NOT add `env_file: ../.env` here (the runner needs no app
  # secrets). For cross-tenant / untrusted multi-tenant workloads use a
  # per-session VM via SANDBOX_BACKEND=daytona instead.
