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. transformBlockScoping transforms let and const variable declarations into var
  2. transformBlockScoping renames colliding variable identifiers across nested block scopes
  3. transformBlockScoping wraps loop body in a closure function when loop variable is captured
  4. transformBlockScoping throwIfClosureRequired option throws error when loop closure is needed
  5. transformBlockScoping tdz option inserts runtime temporal dead zone validation
  6. transformBlockScoping preserves variable scoping and closure execution semantics in runtime
