When trying to `rover subgraph check` a subgraph schema that uses a `@shareable` directive without either linking it or directly declaring it, I get the following error:

```auto
Unknown directive "@shareable". If you meant the "@shareable" federation 2 directive, note that this schema is a federation 1 schema. To be a federation 2 schema, it needs to @link to the federation specifcation v2

```

What exactly causes the command to assume a “federation 1 schema”? I’m using rover `0.10.0` and my supergraph, in spite of now being a `v2` one, previously was a `v1.9` one

`rover subgraph check` does not do any composition. It takes your schema file and sends it to GraphOS where there your graph settings determine what version of Federation you are using.

The `@shareable` error is a common issue when upgrading from Fed v1 to v2. See how to resolve that in our [Migrating from Fed 1](https://www.apollographql.com/docs/federation/federation-2/new-in-federation-2#value-types) guide
