⬡ Polyhedron Note

The ⬡ Polyhedron Note is a coloured card that lives inside your workflow: a bold heading, a free-text body, and a colour row right on the node. That's the entire feature list, and it's enough. It exists because the part of ComfyUI that's worst at storing information is your memory, and the second-worst is a text file that lives outside the graph.

Concretely: the seed that worked, the LoRA this workflow was tuned for, the "don't touch CFG above 1.5 on this model" warning you figured out the hard way, the steps-and-shift recipe you want to replicate next week. That's what goes in the body. The heading gives the card a job ("WAN 2.2 - 8 step, shift 5"), and the colour row tells you at a glance which region of a busy canvas the note belongs to.

How it works

There is no mechanism to break. The note has no inputs and no outputs, so it's never executed and costs nothing when you queue a prompt - it can't slow a run, can't break one, can't be wired wrong. It just rides along in the workflow JSON, so it survives saving, sharing, and reloading like any other node state.

The colour row is the one detail that's cleverer than it looks. It sets exactly the same ten choices (including "none") as ComfyUI's own right-click → Colors menu, and each swatch is painted with the colour the node will actually take - so the two can never disagree about what "yellow" means. If you don't want the row taking up space, fold it away with the chevron.

Using it well

• As a settings sheet. Pin the seed, resolution, and sampler recipe for the current graph so a shared workflow carries its own operating manual.
• As a version note. "Requires Wan 2.2, GGUF Q8, Kijai wrapper" beats rediscovering it from the error message.
• As a wire-into target. Plenty of this pack's nodes emit a STRING info readout - the loaders, Media Info, Audio Stretch. Wire one of those into a note's body and the note becomes a live status display of what the graph actually did on its last run.

Installing it

It's part of the ⬡ Polyhedron Suite pack. ComfyUI Manager → search "Polyhedron Suite" → install, or:

cd ComfyUI/custom_nodes
git clone https://github.com/PolyhedronAI/ComfyUI-PolyhedronLoRAStack.git
# restart ComfyUI

No dependencies to install.

Gotchas

One: don't mistake it for a prompt note. Because it never executes, you can't feed its text into a CLIP encoder or a Save node's metadata path - for text that has to travel, use ⬡ Polyhedron CLIP Text Encode's own comment fields or a plain text node wired where it's needed. The Note is for humans. And if the card renders blank under ComfyUI's new Nodes 2.0 (Modern Node Design) renderer, that's the pack's classic-canvas widgets, not your workflow - flip Modern Node Design off in Settings and it draws again.
