Renderer handoff review

Review the Markdown you will actually publish

The review follows the source or generated Markdown for this tool, checks structural handoff risks, and keeps CommonMark/GFM/host-specific boundaries visible before copy or export.

Copyable handoff summary

Review summary will appear here.

CommonMark defines the core syntax, while GitHub Flavored Markdown and publishing systems add extensions such as tables, task lists, autolinks, footnotes, front matter and renderer-specific raw-HTML behavior. This review is local and never fetches links.

Multi-footnote builder & collision audit

Build a complete footnote block instead of one reference at a time. Add IDs and definitions, detect duplicate identifiers, and export a copy-ready references + definitions bundle.

Ready.

Footnote rendering is platform-dependent. The builder validates IDs and Markdown structure, but the final appearance should be checked in the publishing renderer you actually use.

What this Markdown result proves

Markdown portability depends on the exact source and the renderer that consumes it.

What to review before handoff

Review fences, headings, links, extension syntax and generated output before publishing; source-level checks do not prove remote links or repository-specific style rules.
