True when the Invoice represents a shadow bill — a capitated submission under Ontario's
FHO/FHN models where payment is via capitation and the bill is submitted for tracking and
utilization-reporting purposes only. Derived from Oscar Pro's `billing_on_cheader1.status = 'H'`
(Capitated).
When true, `Invoice.totalGross` reflects the shadow bill value (typically a fraction of the FFS
rate under FHO/FHN capitation; exact percentages are set by Ontario MoH policy and not encoded
in Oscar source — consult the OHIP Schedule of Benefits + the relevant MoH contract). Consumers
should not expect a payment remittance for shadow bills.
