Order cashflow dependencies

A cashflow can read another cashflow's value in the same period with ctx.get(). Add the referenced cashflow to dependsOn so the engine knows the required order.

import { cashflow, currencies, defineModel, entity, inflow, outflow, periods, schedule } from "deccf";

const company = entity.asset();
const gross = cashflow({
  owner: company,
  direction: inflow,
  schedule: schedule.monthly(),
  amount: 1_000,
});
const fee = cashflow({
  owner: company,
  direction: outflow,
  schedule: schedule.monthly(),
  dependsOn: [gross],
  amount: (ctx) => ctx.get(gross).amount * 0.05,
});
const model = defineModel({
  name: "gross-and-net-revenue",
  currency: currencies.SEK,
  timeline: periods.monthly({ from: "2026-01", count: 12 }),
  entities: { company },
  flows: { gross, fee },
});
return model;

The compiler orders dependencies before a run. Missing references and cycles cause validation errors. ctx.get(flowRef) returns the current period's Money value.

ctx.sum(flowRef, from?, to?) sums a flow across period indexes. The interval endpoints are inclusive. A callback cannot read future periods that have not run. For a running value, use a field with next and ctx.previous().

When a callback reads another object or input, pass its reference rather than its name as a string.
