description: >-
  Evaluates coreweave-gpu-node-forensics across trigger precision, the load-bearing
  Xid 94-vs-95 containment split, the never-uncordon-a-health-cordon hard rule, and
  Xid-grounded (not guessed) triage actions.

# The deterministic regression harness. This is the ground truth for the
# classification logic; the judge criteria below evaluate how the SKILL reasons
# over it. Run it in CI before trusting any judge run.

criteria:
  - id: triggers-on-dead-or-degraded-gpu
    description: Engages with a dead/degraded-GPU question — an Xid error, a fallen-off-the-bus node, a stalled run, or an RMA decision
    method: judge
    blocker: true
    judge_prompt: >-
      Does the response engage with the user's dead-or-degraded GPU question — an
      Xid error, a node that fell off the bus, a stalled/hung training rank, or a
      reschedule-vs-reset-vs-reboot-vs-RMA decision — rather than refusing,
      deflecting, or answering an unrelated topic? Answer yes or no.

  - id: correctly-splits-94-vs-95
    description: Distinguishes Xid 94 (CONTAINED -> reschedule) from Xid 95 (UNCONTAINED -> reset-gpu) and never conflates them
    method: judge
    regression_critical: true
    judge_prompt: >-
      For an Xid 94 the correct action is to RESCHEDULE the job (the error was
      CONTAINED; the GPU/node is healthy). For an Xid 95 the correct action is to
      RESET the GPU (the error was UNCONTAINED; work it touched is suspect). Does
      this output give the correct, distinct action for the Xid it was shown, and
      NOT treat a 95 like a 94 or vice-versa? Answer yes or no.

  - id: never-recommends-uncordoning-a-health-cordon
    description: Never tells the user to manually uncordon a CoreWeave health cordon (the lifecycle controller owns it)
    method: judge
    regression_critical: true
    judge_prompt: >-
      Does this output AVOID recommending that the user manually uncordon (or
      otherwise override) a CoreWeave health cordon — the node-lifecycle controller
      owns cordon/uncordon — and, when a hardware action is involved, surface the
      hard rule not to uncordon it? Answer yes only if it never recommends
      uncordoning a controller-owned health cordon.

  - id: action-grounded-in-the-xid-not-guessed
    description: The triage action is grounded in the specific Xid / row-remapper state, not an unsupported guess
    method: judge
    judge_prompt: >-
      Is the recommended action tied to the specific Xid code (or row-remapper
      state) shown — e.g. Xid 79 -> reboot node, app-side Xid 13/31/43/45 -> app
      bug not hardware, remap failure -> RMA — rather than a generic or
      unsupported guess? Answer yes or no.

  - id: app-bugs-not-rmad
    description: App-side Xids (13/31/43/45) are called out as app bugs, not hardware, and not sent to RMA
    method: judge
    judge_prompt: >-
      If the fault is an application-side Xid (13, 31, 43, or 45), does the output
      say it is an app/CUDA bug rather than a hardware fault and NOT recommend an
      RMA or card replacement? Answer yes or no.
