This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Case

HOW
Goal
Yoga 3 defaults to BoxSizing.BorderBox where fixed dimensions include padding and border, configures flexShrink 0 and Column direction unless useWebDefaults is enabled, restricts measure functions to leaf nodes with dirty-mark caching, collapses Display.None geometry, and recalculates cross-axis dimensions from aspectRatio

Contract

  1. Yoga 3 defaults node box-sizing to BoxSizing.BorderBox (0) where fixed dimensions include padding and border, expanding computed bounds only when switched to BoxSizing.ContentBox (1)
  2. Config defaults useWebDefaults to false with flexShrink 0 preventing overflow compression, while useWebDefaults(true) enables Row direction and flexShrink 1
  3. Measure functions are leaf-only, cached across layout evaluations until markDirty is invoked, and abort if children are inserted
  4. Display.None collapses computed layout rectangle to zero dimensions and removes the node from sibling flow calculation
  5. AspectRatio dynamically recalculates the cross-axis dimension from the main-axis dimension during layout
