C553 — Recover one clutch from nested envelopes

Question

Are487/473,444/430 and350/336 independent compression measurements?

Inputs

{
  "envelopes": [
    [
      487,
      473
    ],
    [
      444,
      430
    ],
    [
      350,
      336
    ]
  ]

Results

  "removed_prefixes": [

      43
    ],
    [
      94,
      94
    ]
  ]
}

Finding

All three envelopes express the same14-year compression after equal prefixes43 and94 are removed. The maximum nonoverlap envelope is a source model, not a literal succession of biographies.

Reassessment

Distinguish translating the whole root from moving a single boundary.

Checks

{
  "same_compression": true,
  "same_prefix": true
}
