// Employee roles: what a worker declares they do.
//
// The properties here are the ones the conversational flow depends on and that
// no amount of frontend testing can establish, because they are decided by a
// SQL predicate and a derived column:
//
//	THE OPERATOR IS NOT THE WORKER. An employer records a role for somebody
//	else. If the subject were derived from the session — as created_by
//	legitimately is — every role would be filed against whoever was signed in.
//
//	A WORKER HOLDS MANY ROLES. There is deliberately no uniqueness on the
//	worker, so a second declaration is a second row and a role already marked
//	`placed` survives the worker declaring the same category again. The panel
//	promises exactly this in its review step: "The worker can hold more than one
//	role — recording this does not replace an existing one."
