C537 — Distinguish bilateral expansion from a mixed comparison

Question

How do the350 and336 displays arise from the same161 spine?

Inputs

{
  "original_triple": [
    1728,
    1567,
    1406
  ],
  "held_midpoint": 1567

  "uniformly_expanded_triple_diagnostic": [

  ],
  "uniform_outer_width": 350,
  "one_arm_expanded_with_original_terminal": 336,
  "historical_outer_width": 322
}

Finding

Both arms expanded give175+175=350. Expanding only the Ishmael arm while retaining the original terminal gives175+161=336. The generated1392 companion is only the algebraic fixed-midpoint display, not a newly admitted historical node.

Reassessment

Resolve the147/161/175 progression and its14-unit connection to later clutch operations.
