# Sandbox CI: the keyless real-kernel confinement proofs. A separate workflow
# from ci.yml because the axis is different — these jobs fan out over
# OS×runner (kernel capabilities), not node versions. The Landlock launcher
# arrives from the registry with `pnpm install` (the npm package family
# `node-addon-landlock-run`, built and released from its own repository), so
# these legs exercise the true consumer path — nothing is compiled here.

  # Keyless real-kernel sandbox proofs (sandbox Agent Note § Testing): each ladder
  # rung is only provable on a host where it enforces, so this job fans out
  # an OS×runner matrix — bwrap and Landlock on Linux (separate legs: the
  # Landlock files force the bwrap rung off, so each leg proves exactly one
  # rung; Landlock twice, once per architecture, each confining through the
  # registry-installed launcher), Seatbelt on macOS (sandbox-exec ships with
  # the OS). One node
  # version only: kernel confinement does not vary by node, and ci.yml's
  # node matrix already covers the node axis.
  #
  # The e2e files self-skip where their runner is absent, so a leg that lost
  # its runner (no bwrap, kernel without Landlock, macOS without
  # sandbox-exec) would otherwise pass as a false green — the same trap
  # e2e.yml's key preflight guards against. Each leg therefore asserts BOTH
  # its platform files actually ran: `Test Files  2 passed (2)`, no skips.
