Live node was 'forked', looping 'no AnyTrust reader configured for AnyTrust message (header byte 0x88)'. ApeChain (Caldera) posts AnyTrust DA certs; the earlier 'pure rollup' fix removed the DAS reader. Set chain-config DataAvailabilityCommittee=true (matching every other AnyTrust chain in repo, required by nitro v3.10.1 when DA enabled) and add das rest-aggregator https://apechain.calderachain.xyz/rest-aggregator (from official Caldera node config).
