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. prometheus.NewHistogram creates a Histogram metric with specified name and help string, defaulting to prometheus.DefBuckets when Buckets option is omitted.
  2. Histogram.Observe records observations, accumulating total sample count and sample sum across all calls.
  3. Histogram.Observe increments cumulative bucket counts for all configured upper bounds greater than or equal to the observed value.
  4. prometheus.LinearBuckets and prometheus.ExponentialBuckets generate expected slice bounds for histogram bucket configuration.
  5. Histogram registers with prometheus.Registry and gathers into a dto.MetricFamily of type MetricType_HISTOGRAM containing sample count and bucket distributions.
