C990 — Partition compatibility control

Question

Would an arbitrary nearby allocation produce the same calibrated factor?

Inputs

{
  "diagnostic_fraction": "1/25",
  "calendar": 364
}

Results

{
  "diagnostic_E": "312/287",
  "difference_from_source_E": "1/6601",
  "status": "unadmitted algebraic control"
}

Finding

Replacing1/26 by1/25 changes the factor by1/6601. Calendar-and-partition compatibility is substantive, although reverse-solving prior identities is not independent evidence.

Reassessment

Determine how the three allocation fractions compose.

Checks

  "changed": true,
  "difference": true
}
