Start by triaging the TODOs across src/gateway/opcodes, src/gateway/util, src/gateway/events, and src/gateway/listener/listener.ts, beginning with the opcode or event entry point for one narrowly scoped item. Check the surrounding implementation and existing gateway behavior; done requires resolving a defined TODO and updating this tracking list, but the issue does not specify tests or acceptance criteria.
