# Evolution 72 — Initial Audit

- Branch `evolution-72`, from `evolution-71` at `16d8d1673`.
- E71 implementation `6fb7adcf2`, audit `f86b974`, evidence `9b4736b`, replica `e4c271650`.
- Reproduced **29/29** E68–E71 tests; E71 gates 11/5/4; E70 11/7/2.
- E70 original endurance 163.4645 h; E71 recomputation 163.894 h. Both preserved in
  `artifacts/e72/baseline-reconciliation.json`: E70 counted workers alive at stop; E71 counted all worker rows,
  including killed/replaced workers. The 0.4295 h difference is a population difference, not a correction.
- E71 productivity: 91.04% (16w), 77.18% (64w); 5.3181 productive hours.
- E72 found the 500-worker failure cause: CPU oversubscription made tasks exceed leases; resource-aware admission
  now caps concurrency and sizes leases.
