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.

Case
FIX- Goal
- Parse an ambiguous date string in Python without silently getting the wrong day
- Packages
- Symbols
-
- dateutil.parser.parse
- relativedelta
- Environment
- python 3.12

Contract
- parse an ISO timestamp and an ambiguous numeric date
- assert dayfirst decides between 03/04 readings
- assert an unparseable string raises rather than guessing
- assert relativedelta adds calendar months, not 30 days
