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. StaticRow implements pgx.CollectableRow and pgx.Rows for offline testing and custom mapping
  2. CollectableRow.FieldDescriptions returns column names, OIDs, and format codes
  3. CollectableRow.Scan decodes column values into destination pointers and skips nil destinations
  4. CollectableRow.Values and RawValues return decoded any slices and raw byte slices
  5. CollectableRow.Scan returns pgx.ScanArgError with column index and field name on type mismatch
  6. pgx.RowToStructByName, pgx.RowToStructByPos, and pgx.RowToMap map CollectableRow into Go structs and maps
  7. Custom pgx.RowToFunc mappers validate and transform CollectableRow instances
  8. pgx.CollectRows and pgx.CollectExactlyOneRow iterate rows streams using pgx.RowToFunc mappers
  9. Dynamic column lookup resolves column values by name via CollectableRow.FieldDescriptions
