C676 — Reconstruct the recovered35 phase pair

Question

What exact coordinates result from withdrawing2.5 at both normalized endpoints?

    "5783/2",
    "5703/2"
  ],
  "N_coordinates": [
    2891,
    2851
  ],
  "withdrawal": "5/2"
}

Finding

Withdrawing2.5 from both normalized endpoints recovers width35 and changes the displayed suffix: the Tishri coordinates land on Nisan labels, and vice versa. The apparent integer-label ambiguity is resolved by the exact half-year convention.

Reassessment

Generate the two40 brackets and their common120 field.
