The magnitude runs from 0 for unchanged text to 1 for complete replacement. It measures definition wording only—not authorship, quality, or community impact.
The text snapshots are preserved, but some editor, note, or timestamp details were not recorded in the legacy history.
Select two current candidates to see their exact wording differences. Removed text belongs to the first selection; added text belongs to the second.

| Jul 21, 2026, 2:26 PM UTC | Definition 1 · revision 1 | Comment | Make it precise: say failure happens under cyclic loading below the yield strength, and name the three stages (crack initiation, propagation, final fracture).Legacy association inferred |
