## Specification

`ScheduleTable` preset. Cost, in-service date (**not** purchase date, labeled explicitly), life, method, convention, accumulated depreciation, NBV. Book and tax books in parallel with the difference shown. Disposal shows the working: `Proceeds − NBV = Gain/(Loss)`. NBV can never breach salvage — asserted.

## Rules this component obeys

Money is minor units, never floats. `null` is not `0` and neither is redacted. Negatives render in accounting parentheses with the parenthesis column reserved on both sides. Debit and credit are two columns. Per-currency decimal places. Polarity is explicit — up is not always good. Every figure states its period, entity, currency, basis and as-of.
