+# LATE_FEE_DECIMAL config verification and fix
+
+Date: 2026-07-22
+
+## Scope
+
+- Daily late-fee recalculation now rounds each charge detail late-fee item by `LATE_FEE_DECIMAL` before summing.
+- Accounting split adjustment write-back now allocates child `lateFee` by `LATE_FEE_DECIMAL` for both water-ratio split and fee-component split.
+- Unsold adjustment and split adjustment frontend forms no longer expose the inactive "calculate late fee" switch. Split water preview also no longer shows an always-empty child late-fee column.
+
+## Non-scope
+
+- Payment, bank reconciliation, and list/detail display flows continue to use the stored `lateFee` amount and existing money display rules.
+- Unsold/open-bill/manual billing style flows that only set `lateFeeBeginDate` remain unchanged; they do not calculate late-fee amount in that path.
+
+## Verification
+
+- `mvn -q -pl sw-business/sw-business-server -am -Dtest=LateFeeConfigResolverTest,LateFeeDailyCalculatorTest,LateFeeRecalculationServiceTest,LateFeeDateModeCalculatorTest,AccountingAdjustActionServiceImplTest test` passed.
+- `node --test src/views/accountProcess/unsoldAdjustment/components/UnsoldAdjustmentForm.contract.test.mjs src/views/accountProcess/unsoldAdjustment/components/SplitAdjustmentForm.contract.test.mjs` passed: 11/11.
+- `git diff --check` passed in `water-backend` and `water-frontend`.
+- `NODE_OPTIONS=--max-old-space-size=8192 pnpm ts:check --pretty false` still fails on existing project-wide TypeScript errors; the captured log had no errors for `UnsoldAdjustmentForm.vue` or `SplitAdjustmentForm.vue`.
