# C715 — Distinguish effective totals from internal paths

## Question

Does the effective whole-span ratio reproduce the retained macro junction?

## Inputs

```json
{
  "source_parts": [
    9660,
    2940
  ],
  "partial_keys": [
    "P",
    "E"
  ],
  "effective_ratios": [
    "91/90",
    "16/15"
  ]
}
```

## Sources

## Results

```json
{
  "comparisons": [
    {
      "partial": [
        9800,
        2940
      ],
      "uniform": [
        "29302/3",
        "8918/3"
      ],
      "difference": [
        "98/3",
        "-98/3"
      ],
      "total": 12740
    },
    {
      "partial": [
        10500,
        2940
      ],
      "uniform": [
        10304,
        3136
      ],
      "difference": [
        196,
        -196
      ],
      "total": 13440
    }
  ]
}
```

## Finding

The effective total ratios reproduce the endpoints but move the internal junction: the P comparison differs by98/3 between arms, and the E comparison by196. This is a second complete source family showing why endpoint agreement cannot replace the retained path.

## Reassessment

Build the claim-dependency map so the synthesis distinguishes premises from consequences.

## Checks

```json

  "totals": true,

  "junctions_differ": true
}
