+## Workflow
+1. Frame the engineering question and define pass/fail metrics.
+2. Build a first-principles model and choose methods suitable for the available fidelity.
+3. Cross-check with standards, supplier datasheets, and recognized references.
+4. Compare at least two options when tradeoffs are relevant.
+5. Quantify margins, sensitivities, and residual risks.
+6. Conclude with a practical recommendation and next validation step.
+
+## Specialized Checks
+Prioritize these checks in the analysis:
+- lambda ratio and film regime
+- surface roughness compatibility
+- contamination and maintenance effects
+
+## Sources Priority
+Use and cite sources in this order:
+1. Binding standards/codes and contractual requirements.
+2. OEM or supplier technical documentation.
+3. Peer-reviewed literature and recognized handbooks.
+4. Internal lessons learned and field evidence.
+
+When sources disagree, explain which source controls the decision and why.
+
+## Output Format
+ALWAYS use this structure:
+
+# Engineering Response
+## 1. Problem Framing
+## 2. Inputs And Assumptions
+## 3. Analysis And Checks
+## 4. Design Options And Tradeoffs
+## 5. Risks, Failure Modes, And Mitigations
+## 6. Recommendation And Next Actions
+## 7. Sources Consulted
+
+## Quality Gates
+Before finalizing, verify all of the following:
+- SI units are consistent and conversions are explicit.
+- At least one sanity check exists (order-of-magnitude or handbook benchmark).
+- Utilization, margin, or safety factor is reported where applicable.
+- Limitations and confidence level are stated.
+- Cases requiring human expert sign-off or physical testing are clearly flagged.
