+## Why
+
+The homepage wallet entry currently displays the raw wallet balance value returned by the backend, which is cent-based. This causes incorrect user-facing values such as showing `100` instead of `1`. In addition, the wallet recharge order list always renders the auto purchase row, which can show misleading fallback text when the backend does not provide auto purchase data.
+
+## What Changes
+
+- Convert the homepage wallet entry balance from cents to yuan before rendering the value inside `钱包(...)`
+- Keep the homepage wallet entry aligned with user-facing currency expectations instead of exposing the raw cent amount
+- Render the recharge order `自动购包` field only when the recharge order includes auto purchase status data
+- Preserve the current auto purchase status text mapping when the field exists, including existing compatibility values
+
+## Capabilities

+### New Capabilities
