📝 WalkthroughWalkthroughAdds a read-only BFX04-01 node-health agent query for bare-metal and Kubernetes environments. It validates GPU nodes and supported GPUd or NVSentinel agents, emits structured results, wires provider configurations, and adds tests and documentation. ChangesNode health validation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to When a node has no GPUs, the new health-agent validation can emit a skip result that downstream validation rejects, causing false failures instead of a valid no-agent outcome; this should be fixed or explicitly accepted before merging.

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.

Add a docstring to fake_run.
fake_run is a function and has no PEP 257 docstring.
As per coding guidelines, “Every function and class must have docstrings following PEP 257.”
