`type.principal_active_invalid`

Principal's active condition is not a test of the record's own fields.

Area 8, Sign-in and identity; not declinable; the next step is usually the agent's.

example

principal {    user: {        subject: Member.handle        active: Member.suspended    }}type Handle = Text {    max_length: 40}entity Member {    id: Uuid    handle: Handle {        unique: true    }    suspended: Bool}

error Member.suspended isn't a condition active: can use

--> main.jadpo:4:17

  |4 |         active: Member.suspended  |                 ^^^^^^^^^^^^^^^^ not a comparison

reason: active: is a condition on Member's own fields, such as Member.<field> == <value>; a field alone says nothing to compare it with.
next: Compare a field of Member with a value (agent)
