+/**
+ * E2E test for the "missed L1 publish" scenario under proposer pipelining.
+ *
+ * Each of 4 nodes holds exactly one validator key. We pick four consecutive slots
+ * (slotZero, slotOne, slotTwo, slotThree) such that the proposers for slotOne, slotTwo, and
+ * slotThree are three distinct validators, then warp to one L1 block before slotZero begins.
+ * The proposer for slotOne is configured to skip its L1 publish.
+ *
+ * With pipelining, the proposer for slot N+1 builds and gossips its checkpoint during slot N,
+ * then publishes that checkpoint to L1 during slot N+1. So gossip-driven `proposed` chain
+ * advances arrive one slot earlier than the L1-driven `checkpointed` advance.
+ *
+ * Expected behavior:
+ *  - During slotZero, the pipelined proposer for slotOne gossips its build → every node's
+ *    `proposed` tip advances to a block at slotOne.
+ *  - During slotOne, the pipelined proposer for slotTwo gossips on top of the slotOne proposal →
+ *    `proposed` advances to a block at slotTwo. Meanwhile the proposer for slotOne attempts L1
+ *    publish but is configured to skip it, so no checkpoint lands.
+ *  - When slotOne ends with no checkpoint mined, every node's archiver prunes the
+ *    uncheckpointed slotOne and slotTwo blocks; we verify rollback via the prune event.
+ *    We then re-enable publishing on the formerly suppressed node so recovery can proceed.
+ *  - During slotTwo, the pipelined proposer for slotThree builds on top of the (now genesis)
+ *    checkpointed tip → `proposed` advances again.
+ *  - During slotThree, that pipelined work is published → `checkpointed` finally advances.
