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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. assert pathToRegexp returns { regexp, keys } and does not mutate an array passed in the second parameter position
  2. assert match parses wildcard *splat matches into string arrays of segments rather than flat strings
  3. assert compile requires non-empty arrays for wildcard tokens and throws TypeError for flat strings or empty arrays
  4. assert match returns params with a null prototype lacking hasOwnProperty and omits absent optional parameter keys
  5. assert compile silently drops an entire multi-parameter optional group when any of its parameters are omitted
  6. assert pathToRegexp enables trailing delimiter matching by default
