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. package manifest specifies Apache-2.0 license, bare-os dependency, and exports for root and package subpaths
  2. declares Env index signature interface and env constant in TypeScript definitions (index.d.ts)
  3. exports a Proxy object delegating environment variable access to bare-os
  4. supports getting, setting, and checking presence of environment variables via property access and the in operator
  5. coerces number and boolean values to strings when setting environment variables
  6. throws an Error when attempting to set non-primitive values such as objects, arrays, functions, or symbols
  7. delegates ownKeys and getOwnPropertyDescriptor traps allowing Object.keys enumeration and descriptor lookup
  8. unsets environment variables on deleteProperty while the trap returns falsish causing Reflect.deleteProperty to evaluate to false
