Sample
Jest environment interface and context configuration

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.

Contract
- @jest/environment package.json declares type definitions entry point ./build/index.d.ts and version 29.7.0
- @jest/environment index.d.ts declares JestEnvironment class with constructor, global, fakeTimers, moduleMocker, getVmContext, setup, and teardown methods
- @jest/environment index.d.ts declares JestEnvironmentConfig interface containing projectConfig and globalConfig
- @jest/environment index.d.ts declares EnvironmentContext type containing console, docblockPragmas, and testPath
- @jest/environment index.d.ts declares Jest interface with fake timer controls, module mocking, and test retries
- @jest/environment index.d.ts declares ModuleWrapper and JestImportMeta type definitions
- CustomTestEnvironment initializes with JestEnvironmentConfig and EnvironmentContext and exposes global state and lifecycle hooks
- CustomTestEnvironment setup and teardown manage environment lifecycle and handleTestEvent processes test runner events
