# AI Mascot IP Display (浠宝/福宝) — Session Summary

## Goal
- Complete and verify the mascot IP形象 system (浠宝/福宝) across all touchpoints: database, backend API, login/registration, profile settings, AI chat display, and floating avatar

## Progress
### Done
- ✅ Investigated all mascot-related files and verified completion state
- ✅ Fixed hardcoded typing indicator in `chat.vue` (`🤖` → `{{ mascotIcon || '🤖' }}`)
- ✅ Added dynamic CSS class `mascot-{code}` to chat nav bar
- ✅ Added mascot-specific nav gradient: `.mascot-xibao` (warm orange), `.mascot-fubao` (golden)
- ✅ Added mascot-specific avatar styling (gradient + colored border)
- ✅ Added welcome icon float animation with per-mascot delays
- ✅ Added mascot selection to `user-edit.vue` (registration flow):
  - Mascot card UI (浠宝/福宝 with gradient icons)
  - `selectMascot(code)` method
  - `form.mascot` field in data
  - `mascot` passed in all API calls (saveUserInfo, directRegister, updateUserInfo)
  - mascot saved to `uni.getStorageSync('userInfo')` on navigation
  - Card styles with active state and gradient backgrounds
- ✅ Verified other mascot components:
  - `MascotEnum.java` ✅ (XIBAO/FUBAO with code, gender, persona)
  - `User.java:95` ✅ (`private String mascot;` field)
  - `AIChatController.java` ✅ (injects mascot_name/mascot_gender/mascot_persona into Dify)
  - `UserMascotController.java` ✅ (POST set/get)
  - `profile.vue` ✅ (mascot-selector with cards)
  - `AIFloatingAvatar.vue` ✅ (reads from storage)
  - `chat.vue` ✅ (reads from userInfo onLoad, mascot-specific styling)

### Remaining
- 🔄 Verify all diagnostics clean
- 🔄 (Optional) Test full mascot flow: login → user-edit mascot selection → profile → AI chat

## Key Decisions
- Added mascot selection to `user-edit.vue` during registration (not login.vue), since WeChat login is one-tap
- Used gradient/card UI matching profile.vue style for consistency
- Saved mascot to `userInfo` storage in `navigateToHome()` to ensure chat.vue reads it immediately

## Critical Context
- Pre-existing LSP warnings (unused `e` variables, string concatenation) — NOT introduced by edits
- 小程序 limits: no optional chaining, no CSS Grid — all CSS uses flexbox
- chat.vue has 4 pre-existing `var` declarations — kept as-is for legacy compatibility
