Plan 006 step 4. experiments/*.json for time_stop_10m_v1, probe_add_v1,
asym_exit_v1, rank_one_bullet_v1, pm1_v1 — bars verbatim from the plan table,
production population, fidelity floors {0.25, 3, 1} from the research doc. Also
hardened evaluate(): n==0 and any uncomputable bar metric -> INCONCLUSIVE (not a
false FAIL). Cohort registers + survives run->adjudicate end-to-end. 25 tests green.
