Diagnose the HLS failure first, then branch into link validation, manifest inspection, or playback retesting.

Keep HLS Error Diagnosis as the classification step before you spread the work into parser, checker, or player surfaces.

Keep HLS diagnosis connected to link validation, playlist inspection, and playback retesting.

• M3U8 Link Checker
  Validate manifest and segment reachability after you classify the error.
• M3U8 Inspector
  Inspect playlist tags when the failure looks structural rather than network-related.
• HLS Player
  Retest playback after you clean up the delivery path.
• HLS playback error
  Use the guide when the browser symptom still needs a higher-level playback classification.

Use diagnosis to classify the failure before you jump between tabs.

• What kinds of issues can this diagnosis page narrow down?
  It helps sort errors into likely buckets such as CORS or origin restrictions, token and authorization failures, missing child playlists or segments, key-loading problems, and playback-context issues like codec or buffering mismatches.
• Does diagnosis replace the Player or Parser lanes?
  No. It gives you a symptom-first explanation layer so you can choose the next tool in a cleaner order. Parser and Player still matter once you know which failure bucket is most likely.
• Why keep diagnosis public instead of hiding it inside the workspace?
  Because symptom searches are strong SEO entry points. A public diagnosis page can rank, explain the problem clearly, and still guide the user into the right execution lane only when needed.
