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 lone negated option (--no-cache) defaults opts().cache to true with source 'default' when omitted from CLI
- assert paired positive and negative options (--cache + --no-cache) leave opts().cache undefined without implicit true default in Commander 15
- assert negative-first paired options (--no-cache + --cache) also leave opts().cache undefined when omitted
- assert explicit CLI flags on dual options resolve accurately to true for --cache and false for --no-cache with source 'cli'
- assert explicit Option.default(true) is required on paired options to restore default true behavior in Commander 15
- assert action handler callback receives undefined for omitted dual options
