Section 97 of 105
94. Evidence, Provenance, Confidence and Uncertainty
Stable section ID: S05-CON-014-SECTION-97 · 28 content blocks
Every material engineering claim shall remain linked to evidence of known provenance.
Evidence records shall identify:
- Source.
- Asset and configuration scope.
- Method.
- Date.
- Responsible person or system.
- Instrument or model.
- Calibration where applicable.
- Applicable limits.
- Result.
- Review and approval status.
- Known uncertainty.
System05 shall distinguish among:
- Direct measurement.
- Inspection.
- Test result.
- Calculation.
- Simulation.
- Manufacturer declaration.
- Professional judgment.
- Historical evidence.
- AI-generated inference.
- Unverified assumption.
Confidence shall not be confused with authority or acceptance. A high-confidence prediction may remain unverified, while an approved conservative decision may be based on limited evidence with explicit safety margins.
Unknown, unavailable, contradictory, stale, or low-quality information shall remain visible.
AI fluency, model confidence, repeated assertion, or visual plausibility shall not constitute engineering evidence.
Where uncertainty could materially affect safety, compatibility, cost, or lifecycle performance, conservative action, additional verification, restricted operation, or independent review shall be required.
