Samples Validation

• Prober initialization followed by staged diagnostics.
• Explicit separation between targeted checks (diagnoseAudio, diagnoseVideo) and comprehensive network probe (startToDiagnose).
• Cleanup and stream lifecycle methods are critical for stable page behavior.

Contradictions and Drift Indicators

• Doc snippet drift:
• Some docs use video options key type while reference/sample prefer rendererType.
• Report shape drift:
• Docs show basicInfo/supportedFeatures whereas sample README also references basicInfoEntries/featureEntries.
• Timeout example variance:
• Docs and sample show different connectTimeout defaults in code snippets.

Recommendations

• Use adapter layer for diagnostic report fields.
• Normalize renderer options through a shared utility in your app.
• Keep browser matrix in your own QA docs and update quarterly.
