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. plugin exports a default factory function returning pre, visitor, and post lifecycle hooks
  2. pre hook initializes declareJestObjGetterIdentifier on plugin context to inject getter helper
  3. visitor identifies and transforms jest.mock call expressions to use the injected getter
  4. visitor rejects non-function second argument in jest.mock with TypeError
  5. visitor rejects out-of-scope variable access in jest.mock module factory with ReferenceError
  6. visitor permits identifiers with mock prefix within jest.mock module factory
  7. visitor supports hoistable jest.unmock calls with a single string literal argument
  8. post hook hoists marked jest calls and variable declarations to the top of the block statement
