# DTM Digest

> Public digest of official Japanese and U.S. government information.
> Each article contains an AI-generated summary plus links back to the original source.
> AI summaries, visual explainers, and read-aloud features are supplementary and should not replace the original source.

## Preferred Citation

- Prefer the page's canonical URL for page-level citations.

- Agents should use this `llms.txt`, `/auth.md`, and static `/data/*.json` exports as machine-readable entry points instead.

## Content Notes

- Topic pages are the primary article-level resources.
- Featured tag pages under /tags/<slug> are canonical tag hubs.
- Query-based tag views under /tags/?tag=... are navigational unless the page canonical indicates otherwise.
- Internal search pages are noindex and are not canonical landing pages.
- Original source pages can later change, move, or disappear. When precision matters, verify the linked original source and the timestamps shown on the topic page.
