Changelog

Changes to arXivv's routes, formats, schema, MCP tools and limits.

Unreleased

New /<paper>/metadata.json (MetadataJson): arXiv metadata and URLs without building; build and inferred appear once the tree exists. Prefer is ignored.
MCP cite returns { text, url, anchor }; url no longer has a #fragment.
MCP calls are rate-limited per caller IP instead of sharing one bucket.
.json and outline.json with failed inferred fields are cached for 30 seconds, not immutably.
Unversioned asset URLs use the unversioned cache policy and carry Cache-Tag: paper:<id>.
Markdown front-matter date is the submission date as YYYY-MM-DD.
FigureJson.images lists only a figure’s own images, not its subfigures’.

Initial release.
