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. assert sqlite.RegisterFunction registers custom user-defined aggregate function implementing AggregateFunction interface
  2. assert custom aggregate Step method processes row inputs and computes accumulated state across dataset
  3. assert custom aggregate WindowValue method returns final scalar result for aggregate queries
  4. assert custom aggregate function executes correctly across GROUP BY partitions
  5. assert custom aggregate handles NULL values and empty datasets without panic
