MDX report log-path correction

Base9201abb, isolated docs-mdx-report-fix. Read CLAUDE.md. CI11877 failed while rendering the evidence-sharing/MCP review page: the unquoted shell brace expansion in its log path became a JavaScript expression instead of documentation text.

Render the two existing log paths as inline code. Review braces in all five files introduced or updated by9201abb; endpoint placeholders and examples must stay in code spans/fences. Correct the earlier report's misleading final-build claim: its checks preceded addition of the report. No product wording or routes change.

Run typecheck and a full Docusaurus production build on the final tree, including this brief and the corrected report. Inspect generated HTML for the affected review and the two user-guide section anchors. Record actual artifact counts, not the earlier unverified51-page claim. Root quality/backend conformity before publication; no principal edit, deployment or agent push.
