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
- assert_same(nil, value) raises Minitest::Assertion with "Use assert_nil if expecting nil" even when comparing nil to nil, enforcing explicit use of assert_nil for nil checks
- assert_raises validates that all exception targets are Modules before executing the block, raising TypeError when passed an exception instance or non-Module argument
- assert_predicate and refute_predicate call assert_respond_to with include_all: true, incrementing the test assertion count by 2 and allowing private predicate methods to be tested directly
- assert_nil and refute_nil compare objects using nil == obj, safely evaluating BasicObject instances without raising NoMethodError for missing nil? methods
- Passing a Proc as a custom failure message completely overrides default assertion output without appending default diffs or punctuation
