Compatibility Problems 1 story

Problems grouped as Compatibility Problems share a specific diagnostic boundary inside Troubleshooting & Failure Modes. The diagnostic focus is whether two devices, applications, versions, standards, drivers, or features are designed to work together, separating unsupported combinations from faults in an otherwise supported configuration. The practical goal is not a universal checklist but a repeatable path from symptom to cause, repair, and verification without expanding into every possible problem on the parent platform.
