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
- pgx.CopyFromFunc returns CopyFromSource backed by generator function
- pgx.CopyFromSource.Next advances stream and returns true when row is generated
- pgx.CopyFromSource.Next returns false when generator returns nil row signaling end of data
- pgx.CopyFromSource.Values returns row slice from current generator invocation
- pgx.CopyFromSource.Err returns nil after clean iteration termination
- pgx.CopyFromSource.Next returns false and stores error when generator returns non-nil error
- pgx.CopyFromSource propagates generator errors via Err and aborts copy
- sample helpers provide iterator-backed copy source, channel-backed copy source, transformation pipelines, and row collection using pgx.CopyFromFunc
