Server (collect.py --diff): - History burst: first record sent full, subsequent as jay_diff_full diffs - Live broadcast: each snapshot diffed against the previous one - Diff payloads tagged with "_diff": true Client (client.py --diff): - Reconstructs full state via jay_merge_full before printing GUI (Connector tab "Diff mode" checkbox): - TcpReader.connect_to() accepts diff_mode; maintains _state dict - Merges incoming diffs before emitting to Dashboard/Plot - Checkbox state persisted to plot_settings.json Both sides default to off; must be enabled consistently on server and client. utils/__init__.py added so utils.jay_diff is importable as a package.
