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
- findIndex matches elements using property path strings, key-value pairs, or partial objects, applies fromIndex offsets, and returns -1 for unfound items or nil collections.
- export identity matches between es-toolkit/compat named export and es-toolkit/compat/findIndex default export
- property name strings match the first item with a truthy value at the specified property or nested path
- two-element arrays match items where the property key equals the expected value
- plain objects perform deep partial matching against collection items
- omitting the predicate defaults to identity matching the first truthy element
- fromIndex offsets start searching from the given index, truncating floats and interpreting negative values from the array end
- null and undefined collections safely return -1 without throwing errors
- array-like objects and strings are converted and searched identically to arrays
