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. typed-query-selector package.json declares type definitions entry point shim.d.ts and version 2.12.2
  2. typed-query-selector shim.d.ts augments ParentNode with querySelector and querySelectorAll returning ParseSelector
  3. typed-query-selector shim.d.ts augments Element with closest returning ParseSelector
  4. typed-query-selector strict.d.ts augments ParentNode and Element with StrictlyParseSelector returning never on invalid selectors
  5. typed-query-selector parser.d.ts exports ParseSelector and StrictlyParseSelector type utilities
  6. typed-query-selector parser.d.ts exports TagNameToElement mapping HTML and SVG tag names to element types
