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. assert coerceTypes: true leaves scalar-to-array uncoerced and fails array validation
  2. assert coerceTypes: true still coerces scalar-to-scalar fields like string integers
  3. assert coerceTypes: 'array' coerces scalar string to array of strings and string integer to array of integers
  4. assert coerceTypes: 'array' coerces single-element array to scalar
  5. assert coerceTypes: 'array' rejects multi-element array when scalar string is expected
