◆ sourceBudget()

KOKKOS_INLINE_FUNCTION SourceBudget openswmm::twoD::gpu::sourceBudget	(	double	volume,
		double	h,
		double	area,
		double	dt,
		double	dry,
		double	rain_rate,
		double	coupling_rate,
		double	infil_rate,
		double	evap_rate )

Compute a donor-limited water-only cell source update without mutating device arrays.

Parameters

[in]	volume	Finite cell water m3 after face transfers; positive part is used with incoming sources, except the no-source fast path returns volume unchanged.
[in]	h	Finite pre-source depth m used for evaporation/infiltration wet/dry ramps.
[in]	area	Finite positive cell area m2.
[in]	dt	Finite nonnegative source interval s.
[in]	dry	Finite positive dry-depth ramp threshold m.
[in]	rain_rate	Finite rainfall m/s; negative rainfall contributes zero.
[in]	coupling_rate	Finite signed coupling m/s, positive into the surface.
[in]	infil_rate	Finite held infiltration demand m/s, negative treated as zero.
[in]	evap_rate	Finite held evaporation demand m/s, negative treated as zero.

Returns: SourceBudget by value: final water m3, nonnegative actual infiltration/evaporation m3, signed actual coupling m3 and applied flag. If every integrated transfer is zero, applied=false; otherwise sinks and outgoing coupling share one availability scale against volume plus inflows.

Note: No general shape/finite validation, allocation, ownership transfer or state booking occurs. Caller writes returned budgets/receipts once; quality/thermal paired transfers are handled outside this water-only kernel. Intended inputs keep all products finite and volume nonnegative.
