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. package manifest defines exports for root, global, constants, and package subpaths with addon configuration and Bare engine >=1.20.0
  2. index.d.ts declares writeFloatBE method on Buffer taking value and optional offset and returning next byte offset
  3. Buffer.prototype.writeFloatBE writes 32-bit big-endian IEEE 754 float values including zero, signed zero, positive, negative, and special float values
  4. Buffer.prototype.writeFloatBE returns next byte offset (offset + 4) and defaults offset to 0 when omitted
  5. Buffer.prototype.writeFloatBE throws TypeError for non-number offset and RangeError for non-integer or out-of-bounds offsets
