# C720 — Register the explanatory family diagram

## Question

Does the exact four-panel visual preserve roles, units and the endpoint operation?

## Inputs

```json
{
  "SVG_sha256": "92b97814e0cd734e53c8709e1f67814cd6a2fcc414b2e7a17419b28203616a57",
  "PNG_sha256": "378ab53134865142578d9b2212d07b9f0e65ea1cf656254149ab2b9da6b5b2f9",
  "visual_review": "root inspected rendered2720×1920 image; panel4 retitled endpoint bridge"
}
```

## Sources

```json
[
  "C632–C690; prior Actual/Rounded bridge; diagram independent arithmetic assertions"
]
```

  },
  "panels": [
    "translated rails",
    "micro calibration",
    "retained macro partition",
    "Actual/Rounded endpoint bridge"
  ]
}
```

## Finding

The diagram makes the four main connections visible and separates day volumes from year spans. It labels native and generated heads and shows the actual endpoint route rather than implying that internal paths coincide.

## Reassessment

Translate explicitly between the two supplied phase charts so their centers cannot be conflated.

## Checks

```json
{
  "vector_only": true,
  "panel_title": true,
  "calibration": true,
  "macro": true
}
```
