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. uuid.SetNodeID sets custom node ID and returns true for byte slices of length 6 or greater and false for shorter slices
  2. uuid.NodeID returns the configured 6-byte node ID slice
  3. uuid.SetClockSequence and uuid.ClockSequence configure and retrieve the 14-bit clock sequence
  4. uuid.GetTime returns valid uuid.Time timestamp and clock sequence without error
  5. uuid.NewUUID generates valid RFC 4122 Version 1 time-based UUID with Version 1 and RFC4122 variant
  6. uuid.UUID NodeID and ClockSequence methods extract the configured node ID and clock sequence from generated UUID v1
  7. uuid.Time UnixTime converts uuid.Time into Unix seconds and nanoseconds
