Description

There doesn't seem to be an available way of retrieving the owner identity (e.g. for reducer caller checks) inside the module.

There's ctx.identity() which is the module identity, useful for self-calling checks — that is, scheduled reducers. But there's no equivalent ctx.owner for checking when the module owner calls the reducer (e.g. with the CLI).

Is there another way to check this, apart from hard-coding the value?

Research direction

Start by reading the module context API around ctx.identity() and the reducer entry points used by the CLI. Determine whether owner identity is exposed during reducer calls, and define a supported way to distinguish module self-calls from calls by the module owner without hard-coding a value.
