- Strict response shape: all 14 RpcSimulateTransactionResult fields with correct nil/empty/null distinctions - Custom JSON-RPC errors: -32602 InvalidParams, -32016 MinContextSlotNotReached with structured contextSlot data - Inner instruction recording with stackHeight (Option<u32>), preserved across InstructionError paths via AssembleInnerInstructions - SPL Token + Token-2022 balance decoding with precise uiAmountString for high-decimals tokens (no float saturation) - Pre/post account snapshots for token balance pre-state - accounts.encoding base58/binary rejection - too-many-accounts cap uses post-ALT-resolved key count - ALT resolve before sigVerify so sigVerify-fail responses carry resolved loadedAddresses - PACKET_DATA_SIZE encoded-length cap matching Agave constants - Log + return-data clamping to spec limits (10KB / 1KB) Live-verified A-to-Z (48/48) against real mainnet CPI swaps, Token-2022 txs, ALT-using txs, vote txs, sigVerify-fail paths, and 50-parallel concurrent simulates. Block-replay running cleanly across 400+ slots with these changes.
