# Seam: target reachability and deployment flow integrity.
# These tests assert the deployment contract of the unified repo:
#   - a deploy.sh exists and accepts <dankclaw|dankserver> and --dry-run
#   - deploy.sh covers both the podman stack and the LLM fleet services
#   - 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.
