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
- CachePolicy.storable evaluates whether an HTTP response can be stored in cache according to Cache-Control headers
- CachePolicy.stale evaluates whether a cached HTTP response has expired based on max-age
- CachePolicy.satisfiesWithoutRevalidation determines if a cached response can satisfy a new incoming HTTP request
- CachePolicy.revalidationHeaders generates conditional request headers including if-none-match for 304 revalidation
- CachePolicy.revalidatedPolicy returns updated policy instance merging cached headers with 304 revalidation response headers
