Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. sqlite.RegisterScalarFunction registers a custom scalar function on the SQLite driver without error
  2. sql.Open opens an in-memory SQLite database connection
  3. Executing queries using the custom scalar function in SELECT projections produces expected transformed values
  4. The custom scalar function can be used in WHERE clauses to filter query results
  5. The custom scalar function handles NULL and missing inputs gracefully
