CLAUDE.md@vault-template claudeA

CLAUDE.md@vault-template is agent-read markdown (claude) from undefined-ui/second-brain-os.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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
…

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

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
