C945 — Component allocation remains hidden

Question

Do the recovered aggregate columns identify the source-appointed split?

Inputs

{
  "source": [
    1650,
    1050
  ],
  "diagnostic_only": [
    1550,
    1150
  ]
}

Sources

[
  "C933",
  "C944"
]

Results

{
  "source": {
    "original": 2700,
    "reverse": 10620,
    "split": [
      1650,
      1050
    ]
  },
  "diagnostic_only": {
    "original": 2700,
    "reverse": 10620,
    "split": [
      1550,
      1150
    ]
  }
}

Finding

Different component allocations give the same two measurements. Aggregate identifiability does not recover the Flood breakpoint or establish an alternative chronology.

Reassessment

Parameterize this information loss without presenting diagnostic splits as source variants.

Checks

{
  "same_original": true,
  "same_reverse": true,
  "different_split": true
}
