- Client.Go-035/036/037: usage+README list advise-supervisory; add session-id guard test; fix write2 README wording
- Client.Python-037/038: drop regressed 'scaffold' from pyproject; add advise-supervisory CLI tests
- Client.Rust-039/040: document write_array_elements/advise-supervisory in design doc; pin outer MxValue data_type==0
- Client.Java-049/050/051: sync CLIENT_VERSION to 0.1.2; add advise-supervisory test; guard negative uint32 inputs (pending windev gradle verification)

Client READMEs also updated for Server-057 add-family normalization wording.
.NET/Go/Python/Rust verified green locally; Java pending windev.
