find_recent_rf_data, _correlate_channel_message_rf_data, the channel payload check (_find_rf_row_matching_chan_payload, _rf_data_matches_chan_payload), the authenticated channel cache (_channel_message_identity, _channel_secrets, _decode_authenticated_channel_identity, _cache_authenticated_channel_rf_data, _find_authenticated_channel_rf_data) and _cleanup_stale_cache_entries move verbatim (AST-identical) to modules/rf_correlation.py. MessageHandler mixes it in, so names, callers (rf_match, scope_gate, multitest) and tests are unchanged, and the cache state stays on the handler, where about 130 test references set or read it, many on object.__new__ instances.
message_handler keeps importing channel_hash_for_key and decrypt_group_text as re-exports.
