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. numberLiteralFromRaw parses integer and floating-point literals with type coercion and raw string preservation
  2. signatures provides instruction signatures mapping WebAssembly opcodes to parameter and result types
  3. signatureForOpcode looks up parameter types for standard and object-prefixed WebAssembly opcodes
  4. instruction and objectInstruction build instruction AST nodes with arguments and locations
  5. withLoc attaches source location metadata to AST nodes
