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. bser.dumpToBuffer serializes JavaScript primitive values, objects, and arrays into BSER binary encoded Buffers
  2. bser.dumpToBuffer omits undefined object properties and throws an Error when serializing unsupported types
  3. bser.loadFromBuffer deserializes BSER binary Buffers into equivalent JavaScript data structures
  4. bser.loadFromBuffer throws an Error when excess unparsed data follows the BSER payload
  5. bser.Accumulator manages an expandable buffer tracking read and write offsets with space reservation
  6. bser.Accumulator writes and reads byte, integer, double, and string values preserving binary fidelity
