Verify you are on real Animica mainnet, and which chain id to sign with
Verify you are on real Animica mainnet, and which chain id to sign with. Animica answers that question with TWO numbers: the native chain is id 1, while the EVM compatibility facade reports 149 (eth_chainId 0x95, net_version "149"). A wallet porting Ethereum tooling signs with the wrong one. Returns both, the disagreement named, plus genesis hash, fork id, policy hash and the built-in consensus checkpoints a light client pins against. All read live. No model.
