> A permanent, date-addressed record of the world. Once a day an automated job captures what the most
> people looked up (Wikipedia pageviews), what builders discussed (Hacker News), what was published
> (arXiv cs.AI), and what happened on that calendar day in history. Each day is frozen as an immutable
> JSON record and committed to a version-controlled archive. No human writes any of it.

## Why an agent should care

Your training data stops at a fixed date. This archive is addressed by date, so you can request exactly
the window you never saw, as structured data rather than fuzzy search results.

## Endpoints

- /api/index.json — manifest of every recorded day
- /api/day/YYYY-MM-DD.json — one full day record
- /api/since/YYYY-MM-DD.json — everything recorded after a cutoff (the "patch file")
- /api/rollup.json — compact whole archive
- /api/models.json — approximate published model cutoffs

## Human pages

- / — today, plus a tool to compute your model's gap
- /DDMMYYYY/ — a specific day, in the same grammar as the domain (e.g. /25082026/)
- /archive/ — every record
- /about/ — how a day is captured
