# The Vault Catalogue — a published vault > The index of published vaults, itself a vault, listed in itself — a submission queue where an entry costs a read key and one line, with published to-do lists and first-class write-key status. *Source: · site v0.2.38 · this file is generated from the same content as the page, so the two cannot drift.

It grants read, and only read — a write attempt is refused by the server’s write gate (the **R1 W0** badge you will see in the chrome). ## See it live, here ## What this vault demonstrates | Feature | How this vault uses it | |---|---| | Recursion, usefully | an index of published vaults that is itself a published vault, listed in itself — [rendered live at /catalogue/](../../../catalogue/index.md) | | Submission queue | an entry costs a read key and one line; everything else is derived by an agent opening the vault | | Published to-do lists | `todo/awaiting-read-key.md` and `todo/awaiting-processing.md` are public, because a named gap gets filled | | First-class write-key status | every entry records whether the write key is escrowed or lost, because a frozen vault can never be corrected | ## What this shape is for Machine-and-human-readable registries that update by pushing to a vault rather than deploying a site. The schema here is deliberately the first instance of what a vault hub would need. ## Derived facts 9 files · 11 KB · 2 commits · markdown, no app · derived from the read key alone by `admin/build/catalogue_derive.py` — the same derivation that populates [the catalogue](../../../catalogue/index.md), where this vault also has an entry. --- *[Site index for agents](../../../llms.txt) · [HTML version](https://sgit.ai/demos/vaults/catalogue/index.html)*
