Finding

Joint Rounded observations restrict two hidden residuals to a bounded line u+v=L−B−R. Nonnegative durations truncate the cell at zero; current derived remainders do not supply independent evidence.

Reassessment

Derive and verify the exact size of that bounded line for interior cells.

Checks

{
  "zero_cell": true,
  "interior_cell": true
}
