# `aristo list` — flat inventory with stale-index advisory

Source: `../aretta-sdk/docs/mockups/11-gap-closures/cli-sessions.md` § "J1.a — `aristo list`".

Default text output: one annotation per line with id, kind, verify level, status; sorted alphabetically by id; footer summary by kind and binding state. The J5 stale-index preflight emits its standard advisory header when the index is older than source.

```console
$ aristo list
warning: .aristo/index.toml may be stale relative to source ([..] files newer than indexed).
         Run `aristo stamp` to refresh.
