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.

HOW- Goal
- Handle ActiveSupport 8.1.3.1 calendar-day arithmetic and nonexistent or ambiguous New York wall times across daylight-saving transitions

- ActiveSupport::VERSION::STRING
- ActiveSupport::TimeZone

Contract
- assert tzinfo-data selects the bundled Ruby data source so the same IANA rules work without an OS zoneinfo directory
- assert adding 1.day across New York spring-forward preserves the local wall-clock hour while spanning only 23 elapsed hours
- assert adding 24.hours across the same transition preserves 24 elapsed hours and lands one wall-clock hour later
- assert TimeZone#local normalizes the nonexistent 02:30 wall time to 03:30 with the daylight offset
- assert TimeZone#local_to_utc rejects that nonexistent wall time with TZInfo::PeriodNotFound
- assert the dst flag to TimeZone#local_to_utc selects the two UTC instants for the repeated fall-back 01:30
- assert TimeZone#local defaults to the daylight occurrence for the ambiguous fall-back wall time
