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 inject throws TypeError when resourceData is not a Buffer instance
  2. assert inject throws an Error when target executable does not exist or is inaccessible
  3. assert inject throws an Error when target file is not a supported binary format
  4. assert inject throws an Error when target binary is missing the postject sentinel fuse
  5. assert inject embeds read-only resource blob into ELF binary and activates sentinel fuse from 0 to 1
  6. assert inject throws an Error when resource section already exists without overwrite option
  7. assert inject overwrites existing resource section when overwrite option is true
  8. assert inject supports custom sentinelFuse configuration option
