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.

Contract

  1. deepAssign modifies target object in place and returns the exact target reference
  2. deepAssign deeply merges nested objects preserving existing target properties
  3. deepAssign merges multiple source objects in left to right order
  4. deepAssign overwrites primitives and null values from source objects
  5. deepAssign merges and deduplicates array elements from source arrays
  6. deepAssign ignores undefined source property values without overwriting target properties
  7. deepAssign gracefully skips null and undefined source object arguments
  8. deepAssign protects against prototype pollution keys including __proto__, constructor, and prototype
  9. mergeConfigs helper deeply merges configuration objects
