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. type(value) returns a Type instance identifying primitive types including undefined, null, boolean, number, string, symbol, and bigint
  2. type(value) identifies integers with isInt32 and isUint32 when numbers are within integer ranges
  3. type(value) identifies object instances including Array, Date, RegExp, Error, Promise, Map, Set, and ArrayBuffer
  4. type(value) identifies TypedArray instances including Uint8Array, Int32Array, and Float64Array
  5. type(value) identifies regular functions, async functions, and generator functions
  6. createTag creates a 4-element Uint32Array type tag, and addTag attaches the tag to an object
  7. checkTag verifies whether an object has a matching type tag previously assigned with addTag
