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. caddy.ParseDuration parses standard duration units including milliseconds, seconds, minutes, and hours
  2. caddy.ParseDuration supports day unit d (24h) including fractional and compound durations
  3. caddy.ParseDuration rejects unsupported units like weeks or years and invalid syntax
  4. caddy.Duration unmarshals duration strings with standard and day units from JSON
  5. caddy.Duration unmarshals numeric nanosecond values from JSON
  6. caddy.Duration marshals to JSON as integer nanoseconds
  7. caddy.Duration returns an error when unmarshaling invalid duration formats from JSON
