[PASS] qcev-node-1: stated head_decision_hash matches the folded chain
[PASS] qcev-node-2: reports the same configuration_hash
[PASS] qcev-node-2: 20 COMMIT_QC + 20 PREPARE_QC verified, chain contiguous from genesis  (head cfa1851d6238ca76)
[PASS] qcev-node-2: stated head_decision_hash matches the folded chain
[PASS] qcev-node-3: reports the same configuration_hash
[PASS] qcev-node-3: 20 COMMIT_QC + 20 PREPARE_QC verified, chain contiguous from genesis  (head cfa1851d6238ca76)
[PASS] qcev-node-3: stated head_decision_hash matches the folded chain
[PASS] qcev-node-4: reports the same configuration_hash
[PASS] qcev-node-4: 20 COMMIT_QC + 20 PREPARE_QC verified, chain contiguous from genesis  (head cfa1851d6238ca76)
[PASS] qcev-node-4: stated head_decision_hash matches the folded chain
[PASS] all nodes: identical decision chain (same sequence -> same digest -> same decision_hash)  (20 decisions)
[PASS] all nodes: identical application state hash after the run  (1e9abd29f3694be3)
[PASS] run spans a view change (decisions committed in more than one view)  (views [0, 1])
[PASS] VIEW_CHANGE_QC for view 1: signatures + quorum
[PASS] AuthorizationCertificate seq 20 issued by qcev-node-1
[PASS] AuthorizationCertificate seq 20 issued by qcev-node-2
[PASS] AuthorizationCertificate seq 20 issued by qcev-node-3
[PASS] AuthorizationCertificate seq 20 issued by qcev-node-4
[PASS] negative control: forged signature -> rejected  (signature of 'qcev-node-1' does not verify)
[PASS] negative control: below quorum (hash recomputed) -> rejected  (2 distinct signers, need 3)
[PASS] negative control: COMMIT votes presented as PREPARE (domain separation) -> rejected  (vote from 'qcev-node-1' is a COMMIT by 'qcev-node-1', need PREPARE)
[PASS] negative control: different decision digest (hash recomputed) -> rejected  (vote from 'qcev-node-1' is for another (sequence, digest))
[PASS] negative control: cross-cluster replay -> rejected  (wrong cluster or epoch)
[PASS] negative control: cross-view replay (hash recomputed) -> rejected  (vote from 'qcev-node-1' is for view 1)
[PASS] negative control: vote content altered after signing -> rejected  (signature of 'qcev-node-1' does not verify)
