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. Pend exports constructor and helper functions
  2. Pend initializes with zero pending tasks, infinite max concurrency, and empty wait queue
  3. createPend helper initializes Pend with specified maximum concurrency limit
  4. go executes tasks asynchronously and wait invokes callback when all tasks finish
  5. max concurrency setting throttles concurrent execution and queues pending tasks until capacity opens
  6. wait receives the first error passed to a task callback
  7. hold manually increments pending count and returns a callback to release the slot
  8. invoking a release callback more than once throws an error
  9. wait on empty pend invokes callback synchronously
  10. runParallel executes tasks concurrently within max concurrency limit and returns ordered results
  11. runParallel rejects when any task yields an error
  12. runSeries executes tasks sequentially in order and collects results
