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
- transform duplicate named capturing groups in regular expressions with babel plugin
- Environment
- node
- Created
- 2026-08-23T18:08:21Z
Contract
- @babel/plugin-transform-duplicate-named-capturing-groups-regex compiles duplicate named capturing groups across disjunction branches into wrapped regex helper
- transformed regex resolves match.groups.<name> for the first branch (YYYY-MM)
- transformed regex resolves match.groups.<name> for the second branch (MM-YYYY)
- transformed regex returns null when input does not match
- String.prototype.replace substitutes $<name> group references correctly using the transformed regex
