1 broken link to fix, otherwise the new troubleshooting pages look good.

Issues

• HIGH src/content/docs/ai-search/troubleshooting/index.mdx line 36: Broken anchor link to #public-endpoint-local-errors. The target heading in api-error-codes.mdx is ## Public endpoint operations, so the correct anchor is #public-endpoint-operations.
• MEDIUM PR description: The Summary section is empty and the documentation checklist items are unchecked. Please fill out the Summary and check off relevant items.

Review complete for PR #31894.

What changed

• Added a new ai-search/troubleshooting/ section with three pages:
  • index.mdx — landing page that routes readers to API or processing error references.
  • api-error-codes.mdx — extensive reference of immediate API, Workers binding, public endpoint, and MCP errors (organized by operation type).
  • processing-error-codes.mdx — reference of asynchronous indexing, sync, and crawl errors (organized by failure category).
• Updated ai-search/platform/limits-pricing.mdx to document two additional limits: Namespaces per account and Instances per cross-instance search request.

Actions taken

• Applied the documentation label.
• Posted a review with one inline suggestion.

Issues found

1. HIGH — src/content/docs/ai-search/troubleshooting/index.mdx line 36 has a broken anchor link (#public-endpoint-local-errors). The heading in api-error-codes.mdx is ## Public endpoint operations, so the anchor should be #public-endpoint-operations. I left an inline suggestion to fix this.
2. MEDIUM — The PR description is empty (Summary not filled out, checklist items unchecked). The author should fill out the Summary and check off applicable items before merge.

No build-breaking MDX syntax issues were found. The content is well-structured and the frontmatter is valid.
