Detailed Description

Replay log (design doc 09 §2, decision D45): the viewer protocol's JSON messages, one per line, each with a leading "t" (seconds since the recording started).

Written plain (.jsonl) or as a sequence of independent zstd frames (.zst, about 10-20x smaller). Each frame holds whole lines and the board snapshot (the keyframe) is a frame of its own, so a run that is killed loses at most the open frame, and any standard tool reads the log (zstd -dc run.jsonl.zst | jq).
