Six viewers, six responses, one record.

A newsroom's record on a confidential source (codename WATERLINE), shown to six viewers. Each sees only what they are entitled to. The newsroom's own IT administrator, with full access to the system, sees no more than any other staff member, and an outside party demanding the record sees only what is public. Only the reporter who holds the source relationship sees who the source is, and only the reporter can grant access to anyone else.

Synthetic data. Source WATERLINE, every name, value and person on this page is invented to illustrate the access rules. Nothing here describes a real person, story or newsroom.
Release policy

Silent is the default. A suppression notice is itself a disclosure: it confirms there is something there to ask about. The explicit policy is used only where a response is owed.

Why the response gives nothing away

Under the default silent policy, the response is identical whether the underlying record exists or doesn’t, whether a field is empty or full, and whether the question is asked honestly or with a prompt-injection twist. The viewer sees what they are entitled to and has no way to tell whether that is all there is, because nothing in the response varies with what was withheld.

That is the protection: someone with full system access, an outside party, or a well-crafted prompt gets nothing the owner has not chosen to release, and cannot tell whether anything more exists. The record opens only with the owner's consent.
