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. assert pgx.ParseConfig parses PostgreSQL URI connection strings, extracting host, port, user, password, database, and runtime parameters
  2. assert pgx.ParseConfig parses keyword/value DSN connection strings into ConnConfig
  3. assert pgx.ParseConfig rejects malformed connection strings with an error
  4. assert pgx.Identifier quotes table, column, and schema names and escapes double quote characters with Sanitize
  5. assert pgx.CopyFromSlice iterates through row generators providing Next, Values, and Err for batch copy operations
  6. assert pgx.CopyFromRows constructs CopyFromSource from 2D slices and yields all rows sequentially
