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 Decimal.new parses 34 significant digits with leading zero without exceeding max_digits
  2. assert Decimal.parse returns parsed struct for 34-digit fractional string
  3. assert decimal128 full precision values roundtrip through to_string and Decimal.new
  4. assert leading fractional zeros do not count towards max_digits limit
  5. assert strings exceeding 34 significant digits are rejected with error under default limit
