# `TrogonProto.Error.V1Alpha1.Visibility`
[🔗](https://github.com/straw-hat-team/beam-monorepo/blob/trogon_proto@v0.13.1/apps/trogon_proto/lib/__generated__/trogon/error/v1alpha1/visibility.pb.ex#L1)

Visibility controls who can see a given error metadata field.

Visibility is an exposure contract for shared descriptors. It is not a
secrecy boundary for data encoded in proto annotations: anyone with the
descriptor can read those keys and values. Internal-only metadata belongs in
runtime enrichment, observability pipelines, or internal-only overlays.

Code generators should reject UNSPECIFIED for emitted error details.

# `t`

```elixir
@type t() ::
  integer() | :VISIBILITY_UNSPECIFIED | :VISIBILITY_PRIVATE | :VISIBILITY_PUBLIC
```
