Revision trail

A revision trail is the dated history of changes to facts, assumptions, conclusions, formulas, entries, disclosures, reviewers, and reasons. It connects versions of a workpaper so a reviewer can see what changed, who changed it, and which new evidence or correction caused the change.

Classify the reason. An arithmetic correction fixes a mechanical error. New evidence changes the known fact set. A revised estimate changes a supported input. A changed accounting conclusion revises how authority applies. These causes have different review implications even when they produce the same final amount.

For example, replacing a proposed entry after receiving a signed amendment is not the same as fixing a transposed debit. Preserve both versions, their issue ID, affected outputs, and reviewer disposition. Reperform downstream schedules and controls after the change.

The trail is more than a saved final file or a folder full of numbered copies. It needs an explicit bridge between versions. Do not punish a supported revision as if every changed answer were an error; careful revision is part of the capstone performance. The trail stops short of approving the revised conclusion. Approval remains with the named reviewer and release gate.
