Calculation records

• Projection summary ending investable Composition record, justified by derivation

  Purpose: Republish the investable balance at the projection horizon.

  Statement: projection/compare.ts#summarizeProjection republishes ProjectionResult.endingInvestable, the nominal-dollar investable balance at the projection horizon, without stated rounding.

  Formula: summary.endingInvestable = result.endingInvestable

  • result.endingInvestable: Whole-run investable endpoint (unit: nominal USD) (domain: finite)

  Timing: projection horizon

  Rounding: none stated

  Limits:

  • A selection, not an aggregation: it takes the whole-run endpoint rather than summing annual rows or selecting the largest annual balance. The valid domain is any completed ProjectionResult with a finite ending value.
