In `@isvctl/configs/providers/node-health-agents.yaml`:
- Around line 19-21: Update the node-health agent args so the --nodes flag and
{{env.BFX04_NODES}} value remain a single argument, preventing removal of the
empty value when the environment variable is unset and allowing Kubernetes
fallback. Add a regression test covering absent BFX04_NODES and verifying the
rendered command behavior.
In `@isvctl/configs/providers/shared/breakfix/query_node_health_agents.py`:
- Around line 42-46: Update the command-override parsing around shlex.split to
catch ValueError for malformed KUBECTL or SSH overrides and convert it into the
existing provider query error flow, ensuring main() emits structured JSON
instead of a traceback. Add a regression test covering an unmatched-quote
override and verifying the structured error output.
- Around line 274-281: Align the no-GPU skip payload from the provider with the
validation behavior in NodeHealthAgentCheck so it is recognized as skipped
rather than failed. Update the provider logic around the gpu_nodes check or the
validator’s handling of that result, and add coverage in
isvtest/tests/test_breakfix.py lines 160-185 that passes the no-GPU result
through NodeHealthAgentCheck and verifies the skip outcome.

Summary
Live GB300 validation
Validated on Mississippi GB300 nodes
a05-p01-dgx-03-c01andb04-p01-dgx-08-c01.fleetintdwas active and running on both nodesNodeHealthAgentCheckpassed for two nodesThe Kubernetes fallback was also exercised on Mississippi and correctly did not pass because its three GPU nodes were not Ready and had no matching agent workload. The direct bare-metal path provides the positive GB300 evidence.

Closes #555
