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 esquery returns an array of matching AST nodes for a node type selector
  2. assert esquery returns matching AST nodes for attribute selectors
  3. assert esquery returns matching AST nodes for child and descendant selectors
  4. assert esquery.parse parses selector strings into attribute and compound selector ASTs
  5. assert esquery.match executes a pre-parsed selector AST against an AST
  6. assert esquery.query performs the same AST query as the main esquery function
  7. assert esquery returns an empty array when no AST nodes match the selector
