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. resource.Merge with conflicting non-empty schema URLs returns a non-nil Resource with SchemaURL set to empty string alongside ErrSchemaURLConflict while merging attributes
  2. resource.Merge overwrites attributes from the first resource with attributes from the second resource on key collision even when a schema URL conflict occurs
  3. resource.Merge with one schemaless resource and one schema-defined resource succeeds without error and adopts the non-empty schema URL
