ok    actual coupled solver completes ledger test
  ok    fractional ownership integrates exact clipped regional area
  ok    liquid geometric and relative-flux ledgers close separately
  ok    nonzero material surface transfer without centroid relabelling
  ok    capillary pressure, area, shape, metric, ownership product rule closes
  ok    uniform-reference monolayer area and ownership energy closes
  ok    real coupled trajectory activates shape and geometry work
  ok    paired regional exchange cancels
  ok    independent native total energy agrees with regional components
  ok    missing transport is detected rather than balanced with a residual source
