C571 — Distinguish endpoint agreement from path identity

Question

Do whole J and terminal-cell E have the same intermediate coordinate?

Results

{
  "whole_J_path": [
    14004,
    "24552/13",
    1404
  ],
  "terminal_E_path": [
    14004,
    1929,
    1404
  ],
  "junction_difference": "525/13"
}

Finding

Both paths end at1404, but whole J moves the junction to24552/13 while terminal E retains1929. The new compression is equality after evaluating total span, not identity of the ordered chronological path.

Reassessment

Use the shared endpoint1404 to reconstruct the Actual-to-Rounded cumulative interface.
