      "local": "Applied in the MCP server itself, on the Sui gRPC path, where no proxy is involved. 0 = the view's read_mask projection; 1 = lossless (ancestor echoes and empty containers dropped, repeated envelopes unwrapped, byte vectors rendered as text); 2 = 1 plus BCS blobs dropped, owners collapsed, repeated columns hoisted, collections grouped or keyed. There is no ABI decoding on this path, but there IS an `args` field: getLogs, suiWatchEvents and the pages expandResult continues carry each Move event's own struct, decoded by the node rather than from an ABI, under `args` — at every tier, tier 0 included. So `args` proves tier 2 only where tier_source is `proxy`; here `_meta.tier` is the only thing that does."
