Run the frozen Stage 1 heterogeneous-feature smoke harness
Source:R/20-stage1-prototype-smoke.R
stage1_candidate_smoke.RdRuns only the single deterministic smoke stratum from
stage1-heterogeneous-v2. C1 and C2 are local prototype functions: neither
is registered as a production Decomposer, and this function does not make
a candidate-selection or biological claim.
