This summary is not the rule. The rule text controls.
When picking a jury for a trial, the whole process has to be written down or recorded. This includes any private conversations that happen at the judge's bench between the lawyers and the judge, away from the jury's hearing.
The only way around this is if both sides in the case agree to skip the recording. Otherwise, everything said during jury selection becomes part of the official record.
This matters because it protects everyone's rights. If something goes wrong during jury selection, like an unfair question or an improper decision about who gets picked, there needs to be a written record to look back on. Without this record, it would be hard to prove what actually happened or to challenge a decision later on.
