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 diffSequences finds common subsequences between two sequences
- assert diffSequences handles identical sequences reporting single full subsequence
- assert diffSequences handles completely disjoint sequences reporting no subsequences
- assert diffSequences handles empty sequences gracefully without errors
- assert diffSequences supports custom equality comparator function
- assert diffSequences throws TypeError when lengths are not numbers or callbacks are not functions
- assert diffSequences throws RangeError for negative lengths or non-safe integers
- assert diffSequences interop export is a callable function
