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. walk exports a function that traverses an ESTree AST synchronously visiting nodes in enter and leave order
  2. walk this.skip skips descending into child nodes of the current AST node during enter traversal
  3. walk this.replace substitutes the matched AST node in the parent tree
  4. walk this.remove deletes the matched AST node from parent array
  5. asyncWalk exports a function that traverses an ESTree AST asynchronously supporting async visitor handlers
  6. asyncWalk this.replace and this.remove work asynchronously during traversal
  7. collectIdentifiers and findNodesAsync helper utilities traverse and query AST nodes using walk and asyncWalk
