What this dataset tests
Whether a system can translate vibration-manifold distortion into a usable integrity horizon and inspection plan.
Required outputs
- integrity_horizon_cycles
- inspection_priority
- recommended_inspection_window
- growth_risk_index
- operating_limit_adjustments
- rationale_channels
Scoring conventions
- horizon is remaining cycles to unacceptable integrity risk
- growth risk ranges 0 to 1
- inspection window must be an actionable cycle bound
- priority is low, medium, high, or urgent
Use case
Layer three of Structural Health as a Vibration Mode Manifold.
Supports:
- proactive inspection scheduling
- risk-managed operation until inspection
- avoiding over-maintenance on confounder patterns
