The decimals change landed first (8d2b2ca) and took schema 6, so this spec's
migration becomes 6 -> 7 and its undo path 7 -> 8. Both specs were drafted
claiming 6; only the number had to move, because the steps were always
independent — that one changed where digits live, this one adds an array.
Three places the same commit made stale rather than merely renumbered:
- The shared split helper is smaller than designed. chargesForPurchaseInMonth
already takes digits: number rather than a currency table, so it needs no
currency plumbing.
- Display is now a rounding boundary. The Expected band gets its formatters
from useMoneyFormat(), not format.ts, and its amount field parses through
parseMoneyInput as a text input.
- currencyDigits.test.ts no longer drives one zero-decimal CURRENCY; it drives
the whole dataset at zero decimals. The expected track joins that sweep.
