Description
There is currently no way to recover the data created in the transformed data block. Because that can involve randomization now, it's not possible to recreate on the outside.
There's an associated issue in the stan-dev/stanc3 repo for making the necessary changes to the generated C++ code:

Research direction
Start by reading stan-dev/stanc3 issue 1522 alongside this issue to understand the required generated C++ changes. Identify the affected entry points and tests there; the work is done when transformed-data values, including randomized values, are written alongside posterior samples and can be recovered externally.
