Build Straight-Line Amortization

Overview

Perform bounded exact-decimal straight line amortization and return the calculation with an audit receipt. Closed inputs, fixed precision, deterministic ordering, and typed failures apply.

You receive exact totals and a compact audit receipt for accounting.straight_line_amortization.

When to use it

Scope

Non-goals

• Does not infer currency conversion, calendar basis, accounting policy, or materiality for accounting.straight_line_amortization.
• Does not mutate a ledger, read files, or process unbounded rows for accounting.straight_line_amortization.
