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.

FIX- Goal
- Do timezone-aware date math without the day drifting

Contract
- parse an ISO timestamp into a named zone
- assert the same instant renders as different local days in two zones
- assert adding days across a DST boundary keeps the wall-clock time
- assert an invalid zone is reported rather than silently ignored
