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
- abs returns absolute value for positive, negative, and signed zero inputs
- floor returns the largest integer less than or equal to a given number
- isFinite returns true only for finite number primitives and false for non-numbers and infinities
- isInteger returns true for integer numbers and false for non-integers and non-numbers
- isNaN returns true exclusively for NaN and false for non-NaN values including strings
- isNegativeZero correctly distinguishes -0 from +0 and other values
- max and min compute multi-argument numeric extremums correctly
- mod computes mathematical positive modulo for positive and negative numbers
- pow computes exponentiation base to power
- round returns the value of a number rounded to the nearest integer
- sign returns correct numeric sign for positive, negative, zero, and infinity
- constants expose maxArrayLength, maxSafeInteger, and maxValue with exact standard numeric values
