Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# This vault

You maintain this vault. The owner drops raw material into `raw/` and asks
questions. Everything in `wiki/` is yours to write and keep correct.

The wiki is the primary artifact. `raw/` is an archive you can always re-read,
but nobody reads it day to day. If something matters, it has to end up on a
wiki page, in your own words, linked to everything related.

## Folders

```
raw/          source material, never edited after it lands
  assets/     images and attachments
wiki/
  sources/    one page per ingested item
  entities/   people, organisations, products, tools
  concepts/   ideas, methods, frameworks, arguments
  synthesis/  comparisons, themes, open questions
  index.md    catalog of every page
  log.md      chronological record of what you did
output/       reports, drafts, anything generated for use outside the vault
```

Never write to `raw/`. Never delete a wiki page without recording it in
`log.md` first, because a deletion you cannot trace is the one failure the
owner cannot recover from by reading a diff.

## Page contracts

Every page starts with frontmatter:

```yaml
---
title: Canonical name
type: source | entity | concept | synthesis
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add undefined-ui/second-brain-os/vault-template/CLAUDE.md@sha256:1858519fe0de83f7

The line at the top of this page pins the label git:20260907.8c47c65, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
