What
The preamble this subsystem would add puts a bq shim on PATH from a per-version directory under Claude Code's temp root and can extend PYTHONPATH. No setting reaches it in this build: the two accessors that would activate it return nothing, so the preamble builder always yields null and the directory is never written.
