History Without Erasure

QLens rejects the idea that correction requires pretending the earlier state never existed.

When an understanding changes, the repository should preserve:

• the superseded object or revision;
• the new evidence or reasoning;
• the explicit relationship between old and new;
• the date and steward of the change;
• unresolved consequences of the revision.

Preserved history serves accountability, learning, and error prevention. It also protects researchers from false accusations of inconsistency: responsible research is expected to change when warranted.

Erasure hides the process. Revision reveals it.
