The proof matches an incorrect source

A fictional proofreader confirms that a table exactly matches the manuscript and marks the page complete. A later comparison finds that the table’s totals are internally inconsistent and that an approved correction from the preceding proof was not transferred. Another proof stage introduces a dropped character beside the correction. The quality worksheet supplies a defined denominator and error weights, but a manager reports the resulting per-ten-thousand number as an identical percentage. No official inspection decision is made here. The denominator and weighting table are available for comparison. Distinguish agreement with copy, underlying correctness, correction verification and metric interpretation, and explain which evidence each requires.
