Blockers
- None at Phase 0. Seven cluster nodes unreachable (m2m16, M2M32, M2M32b, M4M36, m4ma, m4mb, m4mc): E7 reports them as not tested unless they come back.
Next safe action
Phase 6: experiments E1–E7 (configs in experiments/configs/, drivers in benchmarks/ and experiments/scripts/,
raw records + manifests under experiments/results/), starting with the E7 bundle for cluster nodes and the FinData
universe/export for E1–E4.
