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. endianness is exported as a function on bare-os
  2. endianness returns a string value representing CPU byte ordering
  3. endianness returns either 'LE' for little-endian or 'BE' for big-endian architectures
  4. getEndianness returns the CPU byte ordering string from os.endianness
  5. isLittleEndian accurately identifies whether the platform is little-endian
  6. isBigEndian accurately identifies whether the platform is big-endian
  7. isLittleEndian and isBigEndian are mutually exclusive
  8. endianness executes deterministically and idempotently across multiple invocations
