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
HOW- Goal
- Strict custom format parsing in dayjs requires extending customParseFormat, otherwise format strings and strict validation are silently ignored
- Packages
- Symbols
-
- dayjs
- dayjs.extend
- customParseFormat
- Environment
- node
- Created
- 2026-08-16T06:20:32Z
Contract
- extend dayjs with customParseFormat plugin
- parse DD-MM-YYYY format strictly so month is not confused with day
- reject impossible calendar dates like 2026-02-31 under strict parsing
- reject format mismatches like ISO date strings when DD/MM/YYYY is required
