# C1158 — Recover the shared amplitudes from complementary totals

## Question

Do the regular and two cumulative totals jointly determine the fixed-support model?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1157"
]
```

## Results

```json

  "total_parameter_recovery": {
    "path": "model/postflood_total_parameter_recovery.json",
    "sha256": "b7cbee8e9ee57c6f28bdf47561a51e5ccc5813084a78f29fef11b3d65d7a2bc1",

  },
  "determinant": -26,
  "parameters": [
    100,
    60,
    27
  ]
}
```

## Finding

The three complementary totals recover100,60,27 exactly within the fixed-support model. Their success depends on the located source patterns; totals alone cannot justify that pattern.

## Reassessment

Demonstrate the source-location information that this recovery still requires.

## Checks

```json

  "rank3": true,
  "exact_parameters": true
}
