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 an info-level observer core filters Debug, captures Info once, and exposes typed structured fields through ContextMap
- assert Logger.With attaches context to the child logger without mutating entries written by the base logger
- assert DPanic logs without panicking on a production logger
- assert zap.Development makes DPanic panic only after the structured entry has been recorded
