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
- Adding calendar months or years with relativedelta clips overflow days to the last valid day of the target month, ensuring dates like January 31 advance to February 28 or 29 without raising an error
- relativedelta distinguishes relative offsets using plural kwargs from absolute field replacements using singular kwargs and allows combining both in a single operation
- Unindexed and nth-instance weekday specifications navigate forward or backward to target weekdays relative to a reference date
- Computing relativedelta between two datetimes decomposes the exact elapsed time into normalized calendar units that reconstruct the original date when added
