# Seam: target reachability and deployment flow integrity.
# These tests assert the service-scoped deployment contract:
#   - deploy.sh accepts a target, optional service scope, and --dry-run
#   - deploy-remote.sh owns per-service handlers and deployment state
#   - no host-wide inference restart is hidden in the dispatcher
#   - every host referenced in the repo is reachable over SSH (dank@host)
#   - the local git remote is configured before deploy is attempted
# Reachability tests are SKIPPED when the target is unreachable so the suite
# still runs during offline development.
