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.

HOW- Goal

- Environment
- node 22.23.2

Contract
- gensync wraps sync and async function handlers into a unified dual-mode operation
- gensync wraps generator functions allowing unified sync and async execution via .sync and .async
- gensync function supports Node.js errback callback pattern via .errback
- gensync.all executes multiple gensync operations concurrently in async mode and sequentially in sync mode
- gensync.race resolves with the first completed operation across sync and async modes
- gensync.race throws GENSYNC_RACE_NONEMPTY when given an empty iterable
- gensync throws GENSYNC_OPTIONS_ERROR when invalid handler options are provided
- gensync throws GENSYNC_ERRBACK_NO_CALLBACK when .errback is invoked without a callback function
- gensync propagates errors thrown inside generator steps in both sync and async modes
