# C920 — Finalize the exact family map

## Question

Can one page show the shared stages and the decisive whole-family distinctions?

## Inputs

```json
{}
```

## Sources

```json
[
  "C914 map",
  "C918 refinements",
  "visually inspected SVG preparation"
]
```

## Results

```json
{
  "exact_map": {
    "path": "deliverables/490d_Chronological_Families_Map_C931.svg",
    "sha256": "beff06f9e3c989e6720992913f2b98d3d4347e0ca6e7e38b2a6518272b897249",
    "bytes": 13690
  },
  "layout": "1500×1120;three stages;six complete-family rows",
  "visual_review": "draft PNG inspected; no overlap or clipping; final wording replaces primitive Digits by Notation"
}
```

## Finding

The map presents source structure, declared construction and complete-field comparison in one page. Its concrete contrasts include restored NT/MT weights, exact P/J stages and retained biography.

## Reassessment

Render and inspect the final SVG, then bind the presentation image.

## Checks

```json
{
  "no_draft": true,
  "notation": true,
  "diagnostic": true,
  "scope": true
}
```
