# V13-FE-008 — Financial formatter slice note
|
|
|
|
- **Requirement:** REQ-FE-FORMAT
|
|
- **API/UI/Test:** UI-FOUND-08 / T-FE-FMT-01
|
|
- **Source:** v60 unit/display-boundary guidance; current `frontend/src/shared/formatters/financial.ts`.
|
|
- **Assumption:** Formatter inputs are already normalized domain values at the FE boundary: currency amount, decimal ratio, quantity, and an instant for as-of display.
|
|
- **Unknown:** Per-account currency and locale policy is not part of this Slice.
|
|
- **Decision Required:** Quant/QA must approve any future rounding or locale change; formatters must not silently infer units.
|
|
|
|
## Applied boundary
|
|
|
|
- Preserved the existing centralized formatter implementation.
|
|
- Characterized missing values, explicit currency marker, decimal-to-percent conversion, bounded quantity precision, KST as-of display, and invalid date handling.
|
|
- No domain calculation, rounding policy, API contract, or database value was changed.
|
|
|
|
