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 with SQLite driver without error
  2. sql.Open opens an in-memory SQLite database connection
  3. Querying the registered scalar function returns the expected transformed string
  4. Executing queries with the custom scalar function in SELECT and WHERE clauses functions properly
