> **DEPRECATED.** This documents Scrollcase box format schema version 2, superseded by schema version 3 and no longer maintained. A version 3 verifier refuses a version 2 box by name rather than reading it, so nothing here describes the current release. Schema version 3 has no direct replacement for this page; its documentation starts at https://scrollcase.dev/

# Scrollcase v2

This is the documentation for **box format schema version 2**, kept exactly as it was published.
Nothing here is maintained. It describes a format the current release refuses to read: Scrollcase v3
rejects a v1 or v2 signed document by name rather than reinterpreting it, and tells the reader which
rebuild it needs.

Read it for one reason only — you are holding a box that was built with Scrollcase v2 and you need
to know what its documents meant. For anything you are building now, go to
[the current documentation](https://scrollcase.dev/).

Two things behave differently here from the rest of the site. These pages are outside the sitemap,
`llms.txt` and `llms-full.txt`, so a search engine or a model is not handed a superseded format as if
it were current. And the JSON Schemas they reference stay served at `/schema/v2/`, unchanged, because
a v2 box's documents name those URLs in their own `$schema` fields.
