chainId reconciliation (registry = live chains = genesis LP-018 map, one way): - Pars mainnet 7070 -> 494949 (live api.pars.network eth_chainId=0x78d65, net_version=494949); Pars testnet 7071 -> 494950, devnet 7072 -> 494951 (matches genesis configs/lp182_chain_id_map.go 4949xx scheme). - Lux devnet 96370 -> 96367 (live api.lux-dev.network reports 96367). - chainRegistry.spec.ts now asserts Pars 494949 (was stale-7070 assert). - Also fixed: configmap-mainnet Pars NETWORK_ID, configmap-testnet Pars NETWORK_ID, branded_build.sh, tools/send_test_txs.py, well-known/explore.json (regenerated from the fixed registry). RPC /ext/bc/<alias>/rpc -> /v1/bc/C/rpc (gateway canonical; each sovereign L1 serves its own C-Chain at /v1/bc/C/rpc). Verified returning blocks before switch: Lux/Zoo/Hanzo/Pars mainnet + Lux testnet. Kept on /ext (their /v1 not up yet): Lux devnet, brand testnets, local-node compose/test-tool URLs. P-chain proxy now dials /v1/bc/P. useChainHeights + luxnet/instance no longer strip /ext/bc/C/rpc; they use the env RPC URL / origin directly so C-chain height + luxnet SDK work under /v1.
