How to read the history?

I'm confused by the [jepsen.log](https://github.com/user-attachments/files/18280447/jepsen.log) against etcd 3.5.15, produced by the README instructions:
```shell
lein run test --workload lock-set --nemesis pause --time-limit 120
```

More specifically, Line 893,894,932,955,996:
```

2024-12-31 07:50:25,980{GMT} INFO [jepsen worker 4] jepsen.util: 4 :ok :add 51 [:not-found "etcdserver: requested lease not found"]
```

Where does the "requested lease not found" come from? Are there retries beyond the log?

Start with the README command `lein run test --workload lock-set --nemesis pause --time-limit 120` and inspect the attached jepsen.log around lines 893, 894, 932, 955, and 996. Trace the logged lease and lock events to explain where `requested lease not found` originates and whether retries appear elsewhere in the log; done means documenting that history clearly.
