# checkpoint-state

An advisory: it explains, and blocks nothing, on a command reaching for a tree's identity, which a revision alone cannot give.

## What it catches

A command reaching for a tree's identity, which a revision alone cannot give.

## Seeing it

A verdict names its rule in brackets, which is how you got here:

```text
advise [checkpoint-state]: ...
```

`magus describe rule checkpoint-state` prints the same entry at a terminal, and
`magus describe rules` lists every rule this workspace enforces.
