Re-check: Failure Injection and Failure Propagation (KB000132713)

Re-visited this article specifically to look for alt-text, image captions, or related text-form coverage of the same content, per request. Findings:

• The article's live DOM (checked via accessibility-tree read and page-text extraction) contains only the abstract text ("This KBA provides a step by step guide to execute a failure injection and propagation simulation") — identical to what the existing extraction (best-practice/failure-injection-and-failure-propagation.md) already captured.
• Scrolling through the full rendered article confirms the body is a long sequence of screenshot images of a slide deck (title slide "Failure Injection/Propagation," then numbered walkthrough slides). Some slides visibly contain caption-style text baked directly into the screenshot image itself (e.g., "Locate the level on which you want to inject failure," "Example 1: Injecting failure on subsystem level") — but this text is part of the raster image, not real DOM text. It was confirmed absent from both the accessibility tree and get_page_text output, so it cannot be extracted as machine-readable text without OCR of each screenshot individually.
• No <img> alt-text was found anywhere on the page (an accessibility-tree search for image elements returned zero results), so there is no hidden alt-text to recover either.
• No related/duplicate KB article covering the same failure-injection workflow in prose form was found elsewhere in the MADE Knowledge Base tab (cross-checked against the existing 36-item index in _agent-kb-extraction-index.md — no other article title matches this topic).

Conclusion

The prior extraction's note ("article body consists entirely of screenshot images... no accompanying inline instructional text") is confirmed accurate and unchanged. Nothing new was recovered from this article. If the actual step-by-step text is wanted, it would require OCR of each embedded slide screenshot individually (not attempted here, out of scope for a KB-text extraction pass).
