v2.1.8

Deck

• Drop the 📝 Deck-display marker from Switch (Drawer) and Switch Chain (Drawer). Both are routing-only nodes with no user-editable widgets, so surfacing them on the Deck main screen wasted a card. The marker remains on Drawer nodes that actually carry meaningful widgets (Seed, Controls, Concat, Size). Workflow JSONs that don't override the node title pick up the new display name automatically; existing workflows with a custom title are unaffected.

Reboot

• Fix /drawer/reboot failing under ComfyUI-Manager-wrapped logging: sys.stdout.close_log() was called before the final logger.info("[Drawer] Restarting..."), which detached the log file used by Manager's logging handler and made the next logger.info raise ValueError: I/O operation on closed file. The asyncio task died before os.execv ran, leaving the server unrestartable and breaking subsequent request logging. Now logs first, then closes the stream; os.execv failure also falls back to sys.__stderr__.write so the error is visible even when the logger is no longer usable.

XYZ Plot

• Embed the full XYZ Plot sweep configuration (axes, widgets, values, zip flags, per-step outputs, settings) into composite images as a self-describing reproducible set: PNG xyz_plot iTXt chunk (zip-compressed) and JPEG/WebP EXIF 0x010E (ImageDescription) with the existing xyz_plot:JSON envelope. Capped at 256 KB; per-step list is dropped if the cap is exceeded, keeping axes + counts intact.
• Surface embedded xyz_plot blobs to Gallery search via a built-in xyzPlot namespace contributor: xyzPlot:axis[steps], xyzPlot:node[KSampler], xyzPlot:value[10], xyzPlot:values_x[...], plus xyzPlot:mode[zip_xy|zip_yz] when zip is active.
• Render embedded xyz_plot blobs as a dedicated "XYZ Plot" section in the lightbox metadata panel (axis rows, zip flags, step counts, Drawer version).
• Extend _read_embedded_meta / _read_exif_meta / _parse_exif_bytes_for_workflow to recognise xyz_plot alongside prompt and workflow.
• Bind XYZ Plot gadget state to the active workflow via workflow.extra.comfyDrawer.xyzPlot so reopening a workflow (including drag-and-drop of a composite PNG whose embedded workflow carries the binding) auto-restores axis selections, value strings, and zip flags. The binding is written only when a sweep completes — touching the XYZ tab without sweeping leaves the workflow untouched, so Deck and manual generations on the same workflow never carry XYZ metadata in their embedded JSON. After a workflow-sourced restore, the in-memory workflow.extra.comfyDrawer.xyzPlot is cleared so subsequent Deck or manual generations on the composite-restored workflow are also clean; the original composite file is untouched, so re-dragging it restores the binding again. localStorage continues to cover the per-browser default for workflows that have never been swept. Restore falls back to nodeTitle + widgetName lookup when the original nodeId has shifted, so workflows imported into a different graph still rebind correctly.
