A replay could draw arrows but not depth, and the recording view said there was nothing to draw even when a result existed. Depth is now quantised per frame (14 B empty, 486 B at the worst frame seen), read from the cache by the same draw path live uses, and the raw-recording note appears only when no result exists. Format version 2; see apps/studio/docs/replay-analysis.md.
