PRACTICE LAB · FOUNDATION

Read the Master — understand the large graph before the first Queue Prompt

This lab closes the Foundation section with practice: learn to read Hansen as a map of systems, inputs, controls, resources and return points without running generation. It is the required transition from “I see hundreds of nodes” to “I see a small number of modules and contracts.”

CONFIRMEDThis is an ARCHVIZ FOUNDATION / EXTENSION exercise. It uses the confirmed Hansen architecture; the goal is graph-reading skill rather than reproducing a specific model.
01 · GOAL

What the learner should be able to do after LAB 04

  • Find BASE CONFIG, INPUTS, MODEL LOADERS, CONTROL, PROCESS modules and OUTPUT without reading every node.
  • Show the active route and distinguish it from connected-but-not-selected and bypassed branches.
  • Name at least five authoritative controls and their consumers.
  • Find model/resource boundaries: where the workflow loads heavy assets and where those assets are reused.
  • Describe one module as INPUT → PROCESS → CHECKPOINT → RETURN.
02 · EXERCISE A

Canvas map: districts first, streets second

  • Open a copy of the Hansen workflow and do not run anything.
  • List the major groups from left to right in a note.
  • Describe the responsibility of each group in one sentence.
  • Do not trace internal links until the map of major modules is complete.
03 · EXERCISE B

Control hunt: find what actually drives the graph

  • Find generation mode 541, PEOPLE mode 543, ControlNet source 456, working resolution 702 and shared steps 771.
  • For each control, find at least one downstream consumer.
  • If a downstream widget shows another value, determine the effective linked value.
04 · EXERCISE C

Resource boundary: where the models live

  • Find the SDXL checkpoint / VAE / ControlNet loaders.
  • Find the FLUX UNet / CLIP / VAE loaders.
  • Mark which loaders serve several downstream modules.
  • Explain why a loader is a resource boundary, not “just another node.”
05 · PASS CRITERIA

LAB 04 is complete when you can explain the graph without running it

  • You can describe INPUT → BASE GENERATION → LOCAL MODULES → FINAL → OUTPUT in 2–3 minutes.
  • You do not confuse the control plane with the data plane.
  • You can point to one bypassed branch and one selector-controlled branch.
  • You can explain why 252 nodes are not 252 independent tasks.
