…ocksonly (36 run) -blocksonly stays off HB and getdata's MSG_WITNESS_BLOCK; relay peers request MSG_CMPCT_BLOCK after sendcmpct v2. Handshake advertises sendaddrv2. Low-work header announces log Core ignore/sync needles at the pending-path height; non-noban does not persist a low-work headers tree. INV of a known fork header may getdata missing bodies. minchainwork / invalid_messages / unrequested stay skip at their fresh official first-fails. Q-41 is 36/267.
Known-header INV getdata stole sendheaders inv_node and failed p2p_sendheaders wait_for_getdata / tip INV announce. Bodies still come from header announcements. Disconnect on a consensus-invalid block and hold it for getblock confirmations=-1. p2p_unrequested_blocks stays skip at :275.
Holding a consensus-invalid submitblock added a second chaintip and failed submitheader_invalid_parent_keeps_one_header_tip. Mark invalid and disconnect; do not hold. -blocksonly (relay off) must not sendcmpct(announce=1) after a new tip.
-blocksonly reports getnetworkinfo.localrelay=false and disconnects P2P txs and tx invs (whitelist relay still allowed). getpeerinfo gains relaytxes. RPC sendraw still accepts when P2P relay is off. p2p_blocksonly stays skip at inbound wait_for_tx (:48).
RPC sendraw notes unbroadcast after accept and re-announces so an inbound peer getdata's the tx (p2p_blocksonly.py:48). Unbroadcast INVs skip the 30s inbound age gate. getpeerinfo exposes whitelist permissions. Official p2p_blocksonly stays skip at first_peer → second_peer wait_for_tx (:74). Q-41 remains 36/267.
STEAL_CLAIMS is process-global. Parallel 256-job pool tests added 8+8 claims and failed steal_chunk_amortizes_claims on CI. Count only while that test is running; serialize the two 256-job cases.
Duplicate sendraw must not re-enter the unbroadcast set (mempool_unbroadcast.py:93). Unbroadcast skips the inbound age gate only when -blocksonly. Inbound announce waits unless noban or relay is off (mempool_reorg.py:71). Official mempool_reorg + mempool_unbroadcast Passed.
…draw testmempoolaccept rolls back with evict_live_txids while relay is off so sendraw can note unbroadcast (p2p_blocksonly.py:48). flush_tx_invs sync-writes INVs onto attached writers. Inbound + relay-on does not let clock_due or current_relay_seq snap INV/GetData a brand-new sendraw after mocktime +300 (mempool_reorg.py:122). Official p2p_blocksonly + mempool_reorg + mempool_unbroadcast Passed. Q-41 is 37/267.
