Rendering ownership

DocVortex provides seven general output formats: Markdown, HTML, LaTeX, DOCX, EPUB, PDF and Structured Content. Its RenderFormat, API, CLI and result export accept only these seven targets. Content List V1/V2 are implemented in MinerU; there are no DocVortex forwarding modules or host imports.

MinerU keeps its existing nine-value RenderFormat, Content List options, render_content_list() and render_content_list_v2() entrypoints. The first returns a flat list; the second returns one list per page. Their field values, geometry, ordering, resource precedence and configuration behavior are unchanged. The ContentType and ContentTypeV2 product constants now belong to mineru.types.

The two projects' RenderFormat classes are distinct. Import the enum belonging to the API being called. Common options, RenderMode, asset interfaces and document types remain shared DocVortex types; only product-specific contracts are owned by MinerU.

Shared fragment API

docvortex.render.fragments supplies the operations required by host renderers:

Operation	Purpose
render_inline_content	Inline Markdown with explicit formula delimiters
render_internal_link	Escaped internal Markdown links
resolve_image_source	Existing image source precedence
normalize_image_source	Shared image path/URL normalization
format_embedded_html	Image prefixes and inline formulas in embedded HTML
strip_index_page_tail	Remove recognized index page-number tails
parse_list_item_marker	Parse list markers without losing inline styling

ListItem, ListItemKind and OrderedListStyle describe list-parser results. These functions delegate to the existing shared implementation rather than maintaining copies. The public module is lightweight; renderer dependencies are loaded on use. MinerU's Content List code imports only public DocVortex interfaces.

Restored DocVortex bundles can still be exported to the seven general formats. For Content List output, pass the shared MiddleJson to MinerU and supply the appropriate asset_base_url, as with its existing public API. JSON document schemas, source parsing, fonts, normalization and saved bundle structure do not change as part of this ownership split.
