## Finding

The complete displacement fields expose plateaus and change points hidden byCreation totals. At every shared node, the bridge displacement equals cumulative displacement minus regular displacement; each mode retains its own source-driven shape.

## Reassessment

Use adjacent differences to recover the exact support of theLXX row changes, including thecollapsedCainanedge.

## Checks

{
  "LXX_head": true,
  "SP_head": true,
  "pointwise_identity": true
