This episode dives into Codex CLI’s move from expensive JSONL duplication to zero-copy, reference-based forks, preserving timestamps while cutting branching latency and disk usage. It also covers temporary side sessions for subagents and a quirky terminal UI bug where buffered keypresses can trigger runaway chained forks.
