The correction stays next to the original. That is a rule of this sample masthead, not a patch after an accident.

A fast desk needs the slot more, because errors leave faster too.

Matrix desk does not treat a correction as an embarrassment.

Block Matrix files this as a sample, not a recommendation. The desk can describe a mechanism, a speaker, and what is still unchecked. It cannot tell a reader what to do with money.

If you keep one line, keep the boundary: Quiet edits hide the mistake from the reader who already left.

Density here is a second source, a time, and a sentence about what is still unknown. A louder adjective does not make the note more complete.

• Who is speaking. Block Matrix names them.
• A number with one source stays out of the headline.
• This sample describes a mechanism. It does not tell you to buy or sell.
• A correction, if it comes, stays on this page instead of disappearing.
