Decode sequence
- The backend reads Solana log notifications for the configured Pump.fun program.
- It analyzes invocation stacks, instruction logs, top-level programs and Program data payloads.
- Each Program data payload is decoded by its known discriminator and Borsh layout.
- When a transaction includes both creation and trading activity, CreateEvent rows are ordered before TradeEvent rows.
- Event time prefers parsed event timestamps and falls back to block time or receive time when needed.
