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. pgtype.UUID parses hyphenated UUID strings, hex UUID strings, and scans into 16-byte arrays
  2. pgtype.UUID marshals to and unmarshals from JSON representations
  3. pgtype.UUID formats valid UUIDs as strings and null UUIDs as driver.Value nil
  4. pgtype.UUID returns an error for invalid UUID strings and unsupported types
  5. pgtype.Timestamp scans time.Time and ISO8601 strings into Timestamp with valid flag
  6. pgtype.Timestamp handles infinity and -infinity values using InfinityModifier
  7. pgtype.Timestamp formats valid timestamps as time.Time and null timestamps as driver.Value nil
  8. pgtype.Timestamptz scans timezone-aware strings and converts to driver.Value time.Time
