# Seam: the deployer's LLM handlers are the twin of the serve scripts'
# artifact gates (the 2026-10-01 crash-loop: a green deploy against a
# missing payload left a restart-looping unit and a dark endpoint).
#
# These tests EXECUTE scripts/deploy-remote.sh's LLM handlers in a sandbox
# (tests/deploy_sandbox.bash): every host touchpoint is a stub, the artifacts
# are fixtures, and the assertions are exit status, the refusal on stderr,
# and what the handler asked systemd to do. A handler that started the unit
# before checking its artifacts would pass a text-grep seam and fail here.
