# Evolution 72 — Final Report

E72 fixed the scheduling failure that invalidated the 500-worker E71 attempt and moved to real sources.

Measured:
- 64 workers, admission cap 16, **0 lease-expiry events**, 1,000 verified tasks, evidence VERIFIED.
- 5/5 real missions accepted: repository worktree with failing→passing pytest, actual-code security review,
  3 arXiv sources, 150-row Iris data, host reliability with injected child failure.
- 3 local models, 18 calls; no remote provider.
- Memory typed 1.0 vs stale 0.0 on a 20-case synthetic suite.
- Scheduling experiment +0.7 with external approval.
- 60/60 security scenarios.
- E72 1.33 worker-hours / 1.09 productive; gates 13/4/3.

Not achieved: cross-host shared state, host reboot, 1h+ missions, standardized external benchmark, remote providers,
10,000 hours, third-party audit.
