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
- Minitest::Mock raises NoMethodError for unmocked calls, raises ArgumentError on argument count mismatch, validates argument types via case equality (===), and raises MockExpectationError on unmet expectations upon calling verify
- Multiple expect registrations for the same method name are consumed in FIFO order, raising MockExpectationError if called more times than registered
- Passing a block to Minitest::Mock#expect evaluates argument conditions at call time and raises MockExpectationError when the block returns false
- Object#stub replaces an existing method on any object for the duration of a block, forwarding arguments to callables or returning static values, and strictly restores the original method even when an exception is raised
- Minitest::Assertions#assert_mock delegates to Mock#verify and converts MockExpectationError into a test assertion failure
