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. pgx.ScanArgError encapsulates column index, field name, and underlying error for row scanning failures
  2. pgx.ScanArgError.Error formats descriptive error string containing field name, column index, and underlying error
  3. pgx.ScanArgError.Unwrap returns underlying error and supports standard errors.Is and errors.As unwrapping
  4. sample helper functions construct, detect, extract details from, and format pgx.ScanArgError
  5. sample.ValidateScannedField validates scanned column values and wraps failures into pgx.ScanArgError
