| * The trusted attributes are those that come from trusted sources. | ||
| * We trust, e.g., listener/zone attributes because they are set by EMQX itself. | ||
| * We trust attributes that come from authenticator, like `auth_expire_at`, `acl`, `is_superuser`, any additional attributes set by the authenticator. | ||
| * We trust attributes that were validated by the authenticator, e.g. `clientid`, `tns` if clientid-based builtin authentication was used. |

you mean by parsing the auth-chain configuration?
for external authenticator, we parse the request templates to find placeholders?

for external authenticators, we of course cannot guess the used templates, so they will need to return trusted attributes (clientinfo mask) explicitly.

this can be easy to support for HTTP authenticator.
but will need to define the contract for other backends

This EIP introduces a provenance-aware security context for
ClientInfousers.Instead of treating full runtime
ClientInfoas authority-bearing data, post-authentication security-sensitive consumers receive a trusted projection derived only from EMQX-controlled fields, authenticator outputs, and explicitly validated client fields.
