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. A match on `Mustermann.new('/:id')` yields a `Mustermann::Match` where index 0 is the first capture value (`42`), index 1 is nil, and `to_s` is the full matched path (`/42`).
  2. In this match shape, `match.params` and `match.to_h` both return `{"id"=>"42"}` while `match['id']` exposes the named capture directly.
