projection-verification

name	projection-verification
description	Use this skill when you need to compare rendered projections against the reference drawing and propose concrete fixes.

projection-verification

Goal

Evaluate whether the current model matches the drawing closely enough.

Required inputs

• /artifacts/projections/*.png

Optional inputs

• /input/reference.png
• /preprocessed/outline_only.png
• /preprocessed/*_ref.png

Required outputs

• /review/compare_report.json
• /review/fix_plan.json

Workflow

1. Read any extracted reference views under /preprocessed/
2. If the needed reference views are missing, call image_editor to extract them from /input/reference.png when possible
3. If extract_view fails, do not use custom to synthesize a replacement reference view crop
4. If no explicit extracted views exist, infer simple matches from filenames under /preprocessed/ and /artifacts/projections/
5. For each matched view, call compare_projection_pair
6. If compare output includes a diff board image, inspect it if needed
7. Summarize mismatches into a concise report
8. Create a patch-oriented fix plan for the builder
9. If comparison inputs are insufficient, write a blocked report that says which reference view could not be established
