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. createEmptySection inserts a new section into the AST metadata and encodes section bytes in the buffer
  2. resizeSectionByteSize adjusts the byte length of an existing section in the AST and buffer
  3. resizeSectionVecSize updates vector element count in section header and updates buffer
  4. removeSections deletes section from AST and removes corresponding bytes from buffer
  5. removeSections and resize functions throw an Error when section does not exist in AST
