HelpDot Documentation Review

Overall Assessment

This is a focused cleanup PR that removes six identical placeholder pages left over from the integration errors project. Each deleted file contained only a stub with a forbidden "Overview" heading, a non-actionable description, and missing required YAML metadata fields. Removing these pages is the correct action -- they provided no value to users or AI retrieval systems and violated multiple governance rules.

Scores Summary

• Readability: 10/10 - The proposed change (deletion of placeholder stubs) strictly improves readability across the help site. No under-construction dead ends remain for the affected directories.
• AI Readiness: 10/10 - Removing pages that lacked keywords, internalScope, task-based headings, and any substantive content eliminates noise from the AI retrieval index.
• Style Compliance: 10/10 - The deleted content violated HELP_AUTHORING_GUIDELINES.md Section 2 (forbidden "Overview" heading), Section 3 (missing keywords and internalScope metadata), Section 6 (no "How to" heading, no realistic search phrases), and TEMPLATE.md (incomplete YAML frontmatter). Deleting it resolves all violations with no new content to evaluate.

Key Findings

• All six files were byte-identical placeholders with the text "This section is under construction. Content will be added in a follow-up PR."
• The # Overview heading is explicitly listed as forbidden in HELP_AUTHORING_GUIDELINES.md Section 2.
• The YAML frontmatter was missing both keywords and internalScope, which are required fields per HELP_AUTHORING_GUIDELINES.md Section 3 and TEMPLATE.md.
• Each parent directory still contains other substantive articles (error-code-specific pages), so no empty directories will result from this deletion.

Recommendations

• Approve as-is. This is a clean, beneficial removal of non-compliant placeholder content.
• No further action is needed regarding empty directories -- all six parent folders retain other files after these deletions.

Add redirects for the deleted troubleshooting overview pages

Deleting this article without updating docs/redirects.csv turns its published URL into a 404 for anyone coming from an existing bookmark, search result, or external link. I checked docs/redirects.csv:913-962: it already contains redirects for many sibling .../Overview pages (including the classic QBO page removed in this commit), but not for this URL or the other four unredirected overview pages deleted here, so those old article links will now break instead of forwarding to the troubleshooting hub.
