Operator decision 2026-10-04 (sebastian): consensus-layer-synced op-stack nodes used to run
with --nodiscover / --disable-discovery and no published p2p port. A 0-peer EL can never
backfill a dropped-gossip gap, so op-node wedges in FCU-SYNCING until L1 derivation
catches up (katana 09-19..26, zircuit, mode). Blocks still arrive only via op-node; EL
peers are for gap-fill. Our own copies now discover each other implicitly.

- Add zircuit-mainnet to conduit-op-reth (ghcr.io/conduitxyz/conduit-op-reth:v2.1.1)
- Add genesis.json/rollup.json from Conduit API with bedrockBlock=32956468 fix
- Add Conduit P2P bootnodes + static peer
- Use ETHEREUM_MAINNET_* vars for L1 (chainid 1) with oplabs op-node:v1.19.3
- Remove zircuit-mainnet op-geth archive/pruned profiles (SLS dependency dead)
- Keep sequencer endpoint and drpc_chain=zircuit-mainnet
SLS-decommission root cause: zircuit1/l2-geth hard-requires Zircuit-hosted
SLS DB that no longer resolves (mainnet-sls-db-global-primary.cluster-ro...
no such host). Migrating to Conduit external-node stack per operator directive.
