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 represents PostgreSQL UUID values with Bytes [16]byte and Valid bool fields
  2. pgtype.UUID implements sql.Scanner parsing 36-character hyphenated and 32-character hex UUID strings and handling nil as invalid
  3. pgtype.UUID implements driver.Valuer returning formatted UUID string for valid UUIDs and nil for invalid UUIDs
  4. pgtype.UUID.String returns hyphenated 36-character UUID string when valid and empty string when invalid
  5. pgtype.UUID provides native ScanUUID and UUIDValue conversion methods
  6. pgtype.UUID marshals to and unmarshals from JSON quoted UUID strings and null
  7. pgtype.Map encodes and scans pgtype.UUID in PostgreSQL text and binary wire formats
  8. sample helpers provide structured creation, parsing, formatting, wire format encoding/decoding, and JSON conversion
