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. CopyFromRows iterates over 2D slice rows with Next and Values
  2. CopyFromRows handles empty row sets with zero iterations and nil error
  3. CopyFromSlice iterates and maps indexed elements to row values
  4. CopyFromSlice captures and reports error returned by next function
  5. CollectCopyRows drains all rows from CopyFromSource into a slice
  6. CollectCopyRows stops and returns error when row evaluation fails
  7. NewSliceCopySource converts generic slice into CopyFromSource
  8. ValidateCopyRows validates column consistency across rows
