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. Configure global UuidFactory with OrderedTimeCodec
  2. Parse a valid RFC 4122 version 1 time-based UUID string
  3. Serialize the UUID instance with native PHP serialize()
  4. Unserialize the payload back into a UuidInterface instance without throwing UnsupportedOperationException
  5. Assert that the reconstituted UUID maintains value equality, version 1 type, and byte identity
  6. Verify OrderedTimeCodec binary encode and decode round-trip functions correctly
