Research direction

The issue names the stan_surv entry point and failure when cores>1, but gives no reproduction or error text. Start by reproducing the stop with a minimal stan_surv call and compare cores=1 with cores>1, then trace the relevant execution path. Done means the behavior is explained and multi-core execution is fixed or its limitation is clearly documented.
