# C969 — Ancestral multiset is insufficient

## Question

Does holding the three ancestral lifespans as a multiset recover their assignment?

## Inputs

```json
{
  "multiset": [
    962,
    969,
    777
  ],
  "capacities": [
    847,
    720,
    653
  ]
}
```

## Sources

```json
[
  "C968"
]
```

## Results

```json
{
  "compatible_assignments": [
    [
      962,
      969,
      777
    ],
    [
      962,
      777,
      969
    ],
    [
      969,
      962,
      777
    ],
    [
      969,
      777,
      962
    ]
  ],
  "status": "finite non-admitted ambiguity diagnostic, not target tally"
}
```

## Finding

Even the known ancestral multiset does not restore row placement: four assignments give the same clipped outputs. Source row identities remain necessary.

## Reassessment

Check the main LXX baseline without changing any SP capacity.

## Checks

```json
{
  "nonunique": true,
  "source_included": true
}
```
