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 Retry.DEFAULT_RETRY_AFTER_MAX equals 21600 seconds (6 hours)
- assert Retry().retry_after_max defaults to 21600
- assert parse_retry_after caps numeric Retry-After strings exceeding 21600 seconds to 21600
- assert get_retry_after caps response Retry-After header exceeding 21600 seconds to 21600
- assert Retry allows configuring custom retry_after_max ceiling
- assert parse_retry_after caps future HTTP-date Retry-After values exceeding 21600 seconds
