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
- With both `--cache` and `--no-cache`, parsing without either flag leaves `program.opts().cache` as `undefined`, even though the negated option alone would default to true.
- Without flags, `program.getOptionValueSource('cache')` is `undefined`, not `default`.
- Parsing `--cache` sets `program.opts().cache` to `true` and `program.getOptionValueSource('cache')` to `cli`.
- Parsing `--no-cache` sets `program.opts().cache` to `false` and `program.getOptionValueSource('cache')` to `cli`.
