…rain/spartan (#23544) ## Summary PR #23344 was dequeued again at https://github.com/AztecProtocol/aztec-packages/actions/runs/26370196367. The flake-flag added in #23528 (`error_regex: "Tx dropped by P2P node"`) wasn't enough — ci3 retries once and the multi-validator web3signer suite has now been seen failing in a second pipelining-related mode that the regex doesn't match. Both observed modes hit the same `should build blocks & attest with multiple validator keys` case: - `Tx dropped by P2P node` at `Promise.all` index 0 (the original mode, ci.aztec-labs.com/9a5fa90aa18f62e7). - Proposer misses the slot's 5-attestation deadline → `AttestationTimeoutError: Timeout collecting attestations for slot 29: 0/5`, followed by `Simulation error: Block 0x… not found in the node. This might indicate a reorg has occurred.` (ci.aztec-labs.com/b91d3218b5e88ae4). Following the same pattern as #23542 for `e2e_ha_full`: collapse the existing error_regex entry into a single `skip: true` so the suite is outright skipped on `merge-train/spartan` until proposer pipelining stabilises. ## Notes - Targets `merge-train/spartan` per yarn-project default base. - Owner kept as @PaLLa (current owner of the entry from #23528). Requested in Slack by @PhilWindle. --- *Created by [claudebox](https://claudebox.work/v2/sessions/dc484e7becc621c7) · group: `slackbot`*

Summary
Add a
.test_patterns.ymlentry to flag the multi-validator web3signer suite as a flake when the first concurrently-submitted tx is dropped by the P2P layer before reaching a proposer. This is what dequeued PR #23344 from the merge queue at 2026-05-23T09:17 (run 26328618812).Investigation
cijob: https://github.com/AztecProtocol/aztec-packages/actions/runs/26328618812/job/77510713955Jest output:
Line 410 is inside the
await Promise.all(sentTransactionPromises.map(async … => waitForTx(aztecNode, txHash)))block. The first of the concurrently-submitted txs never propagates andwaitForTxresolves to a dropped receipt; this is a transient P2P-propagation flake under the proposer-pipelining migration in #23482.Why a new entry?
There is no existing entry covering this suite. The unique error signature is
Tx dropped by P2P node, which appears in the receipt'serrorfield rendered bywaitForTx.Follow-up
Proper fix: investigate why the first tx is occasionally dropped before propagation completes (likely a race between mempool insertion and proposer pickup under pipelining). Same family as the other
merge-train/spartanpipelining flakes; owner palla is the author of the pipelining migration (#23482, which also migrated this suite).Test plan
error_regex: "Tx dropped by P2P node"matches the observed receipt errorsrc/composed/web3signer/e2e_multi_validator_node_key_store.test.ts; the P2P-drop failure now alerts palla on#aztec3-ciinstead of failing the buildCreated by claudebox · group:
