…in validators The proposer-side fix from #23110 (parent checkpointOutHash splice under pipelining) was inlined as a private method on `CheckpointProposalJob`. The validator's block re-execution and checkpoint-proposal validation paths in `proposal_handler.ts` compute the same `previousCheckpointOutHashes` list through the same archiver-driven query, so they have the same off-by-one window: if the parent cp lands on L1 between when the validator pulls and when it re-derives, only the proposer would carry the spliced parent and attestations would mismatch. Extract the proposer's logic into a shared `getPreviousCheckpointOutHashes` helper in `stdlib/src/checkpoint/`. The helper accepts the proposer's already-loaded `proposedCheckpointData` directly, and falls back on `L2BlockSource.getProposedCheckpointData(...)` for callers that don't have it on hand (validator). Wire the helper into the proposer (replacing the private method) and into both validator sites. Add a few diagnostics that helped pinpoint this class of bug: - `prover-node-publisher.ts`: when the L1-recomputed `RootRollupPublicInputs` vector mismatches the prover's, decode the differing indices into labels (`previousArchiveRoot`, `endArchiveRoot`, `outHash`, `checkpointHeaderHashes[i]`, `fees[i].recipient/value`, `constants.*`, `blobPublicInputs[*]`), fetch the L1 `CheckpointLog` for any mismatching `checkpointHeaderHashes[i]`, and emit a structured error log alongside the throw — much easier to triage than the previous opaque dump. - `BlockRollupPublicInputs.toInspect()` and `CheckpointRollupPublicInputs.toInspect()` to keep per-stage orchestrator debug logs short. - Per-stage debug logs in the orchestrator (block-root, block-merge, checkpoint-root) consume the new `toInspect()` outputs. - Lightweight checkpoint builder logs `headerHash` and the size of `previousCheckpointOutHashes` at debug. - Epoch proving job's per-checkpoint start log trimmed to the fields that are actually useful for cross-comparison.
Mirrors the pipelining toggles applied to the rest of the p2p e2e suite (`enableProposerPipelining: true`, `inboxLag: 2`, `minTxsPerBlock: 0`) plus the test-side adjustments needed to keep cross-chain assertions deterministic (`waitForL1ToL2MessageReady` instead of the older `waitForL1ToL2MessageSeen`, longer per-test jest timeout). Intentionally does NOT add the `EpochTestSettler` cheat-code workaround that previously masked the `Root rollup public inputs mismatch`; the helper-based fix earlier in this PR is what unblocks add_rollup under pipelining.

Extract the fix for
outHashes added in #23073 in the proposer so that it can be reused in validators as well. Enables pipelining onadd_rollupe2e p2p test, which was failing because of this bug. Also adds a bunch of logging, which was needed to track down the issue.Builds on top of #23073
