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. JSONB.Set parses string, JSON-serializable values, and nil into Present or Null status
  2. JSONB.Get returns deserialized value for Present status and nil for Null or Undefined status
  3. JSONB.AssignTo assigns bytes, string, or unmarshals into a destination struct
  4. JSONB.EncodeText and DecodeText encode and decode plain JSON text format
  5. JSONB.EncodeBinary prefixes version 1 byte to JSON payload and DecodeBinary verifies version 1 header
  6. JSONB implements database/sql driver.Valuer returning bytes or nil and errors on Undefined status
  7. JSONB implements database/sql.Scanner decoding bytes and setting Null status on nil
