Motorway 0x7

Motorway 0x7 pulls seven keyed values off the MOTORWAY 🚌💨 bus in a single node. It's the "okay, this step really does need seven inputs" lane of agilly1989's ComfyUI Motorway pack - a pipe implementation where everything rides one connection, keyed by string.

The family logic is simple and consistent: MotorwayStart makes an empty bus, on-ramps store values, 0xN ramps pull them out. It's the same anti-wire-clutter instinct as rgthree's Context nodes, implemented as an any-typed key-value bag instead of a typed bundle.

How it works

Same mechanics as every Motorway NxB: the bus comes in, seven _key widgets name what to pull, and ANY (A)–ANY (G) (all *) carry the values out. Bus is cloned at each hop (snapshots, not mutation); keys are exact strings hashed via SHA-256; duplicates overwrite; blank keys do nothing.

A 0x7 tends to appear in video or multi-pass workflows - say, a pass consuming model, positive, negative, latent, vae, start_time and end_time together. If you've genuinely got seven inputs to one node, one ramp beats three smaller ramps scattered around.

Inputs and outputs that matter

• MOTORWAY 🚌💨 (required) - the bus.
• ANY_(A)_key … ANY_(G)_key (optional) - the seven keys.
• Outputs: MOTORWAY 🚌💨 plus ANY (A)–ANY (G).

Installing

cd ComfyUI/custom_nodes
git clone https://github.com/agilly1989/ComfyUI_agilly1989_motorway

or ComfyUI Manager → "ComfyUI_agilly1989_motorway", restart. No pip deps, no model files.

Where people get burned

• 'MotorwayClass' object has no attribute 'hash_' - the pull key isn't on the bus yet. Exact match, so ordering and spelling matter.
• The "seven at once" smell. Before you commit to a 0x7, check whether those inputs actually need to be simultaneous. Sometimes you're one good subgraph away from a 0x4 and a 0x3.
• Beta breakage. README warning is front and center: active development, "IF THINGS BREAK ITS BECAUSE I BROKE IT." Flows drift between releases.

This is a niche lane count. If you're reaching for it weekly, your workflow is either impressively complex or overdue for a refactor - and the Motorway won't tell you which.
