how- ever, can never observe y alone, since the same process inserted x prior to y. 2.6 Monotonic & Append Some of Jepsen’s checkers (e.g. linearizability) allow the verification of arbitrary histories. However registers, the txn-cycle test finds write-read dependency cycles over read-write registers, and the append test uses appends of unique elements to lists. We include realtime dependencies (e.g. T1 com- pletes 1], and append(36, 5) to denote appending 5 to the current value of key 36. T1: r(34, [2 1]), append(36, 5), append(34, 4) T2: append(34, 5) T3: r(34, [2 1 5 4]) Because T1 did not see T2’s append of 5 to
