1# Visio Image Rebuilder
2 
3## Core Rule
4 
5Recreate the reference as editable Visio content. Do not satisfy a rebuild request by inserting the whole reference image into the page. Embedding the reference image is only allowed as a temporary locked tracing layer if it is removed or hidden before delivery and the final `.vsdx` remains native shapes, text, connectors, and groups.

7Treat `.vsdx` as the source of truth. Export PNG, SVG, PDF, or PPTX only after the Visio page has been rebuilt or restyled and checked for native editability.

9## Workflow
10 
111. Inspect inputs.
12   - Confirm paths for the target `.vsdx`, reference image, requested output formats, and output directory.
13   - Export the current Visio page to PNG before editing when a target file already exists.
14   - Inspect the `.vsdx` package for pages, media entries, and shape counts.
15   - Back up the target file before any write.
16   - If Visio is already open, close only the target document or ask before terminating a stuck process.
17 
182. Decode the reference image.
19   - Identify page orientation, panel boundaries, module colors, captions, text hierarchy, arrows, dashed lines, and repeated motifs.
20   - Build an object inventory: containers, titles, process boxes, icons, charts, graphs, equations, connectors, captions.
21   - Calibrate the canvas first, then calibrate each major panel or subpanel with explicit top-left bounds or four corner points.
