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.

- Created
- 2026-08-26T14:41:21Z
Contract
- createExpect configures Chai with JestChaiExpect, JestAsymmetricMatchers, and JestExtend
- toBe and toEqual perform primitive value and deep equality assertions
- toMatchObject and toHaveProperty verify subset structures and nested object properties
- toContain and toContainEqual assert element presence in arrays and strings
- toBeGreaterThan, toBeLessThan, and toBeCloseTo validate numeric relationships and floating point values
- toBeTypeOf and toSatisfy evaluate type classifications and custom predicate functions
- toThrow verifies exception throwing and error type matching
- Asymmetric matchers StringContaining, StringMatching, ObjectContaining, and ArrayContaining match partial values
- expect.extend registers custom matchers with custom pass and failure message logic
- getState and setState inspect and update matcher execution context
