> catalog) plus JSON data render to byte-identical PDFs on every host.
> Built for AI agents — validate/preview/inspect via an MCP server.

## Repository truth
- [Template reference](https://github.com/kengos/shojiku/blob/main/docs/engine/README.md)
- [Diagnostics registry](https://github.com/kengos/shojiku/blob/main/docs/engine/diagnostics.md)
  (both are rendered on this site under /reference/, one route per page,
  each page's own markdown at /data/reference/<page>.md, and llms-full.txt
  below inlines every one of them)
- [Capability record](https://github.com/kengos/shojiku/blob/main/docs/engine/features.md)
  (what shipped and why it is shaped that way, as opposed to how to author
  it. Repository-only: it is not rendered on this site and is not inlined
  below, so fetch it directly. The reader-facing tour is /features.md)
