Subject: [PATCH] Complete TanStack Query v6 migration (#445)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Overview

Complete migration from service layer to TanStack Query v6 with
mutations, queries, and automatic cache management.

## What Was Completed

### Phase 1: Entity Queries & Database Pages ✅
- Created `entity.queries.ts` with query options for weapons,
characters, and summons
- Migrated all database detail pages to use TanStack Query with
`withInitialData()` pattern
- SSR with client-side hydration working correctly

### Phase 2: Server Load Cleanup ✅
- Removed PartyService dependency from teams detail server load
- Server loads now use adapters directly instead of service layer
- Cleaner separation of concerns

### Phase 3: Party.svelte Refactoring ✅
- Removed all PartyService, GridService, and ConflictService
dependencies
- Migrated to TanStack Query mutations for all operations:
  - Grid operations: create, update, delete, swap, move
  - Party operations: update, delete, remix, favorite, unfavorite
- Added swap/move mutations for drag-and-drop operations
- Automatic cache invalidation and query refetching

### Phase 4: Service Layer Removal ✅
- Deleted all service layer files (~1,345 lines removed):
  - `party.service.ts` (620 lines)
  - `grid.service.ts` (450 lines)
  - `conflict.service.ts` (120 lines)
  - `gridOperations.ts` (unused utility)
- Deleted empty `services/` directory
- Created utility functions for cross-cutting concerns:
  - `localId.ts`: Anonymous user local ID management
  - `editKeys.ts`: Edit key management for anonymous editing
  - `party-context.ts`: Extracted PartyContext type

### Phase 5: /teams/new Migration ✅
- Migrated party creation wizard to use TanStack Query mutations
- Replaced all direct adapter calls with mutations (7 locations)
- Maintains existing behavior and flow
- Automatic cache invalidation for newly created parties

## Benefits

### Performance
- Automatic request deduplication
- Better cache utilization across pages
- Background refetching for fresh data
- Optimistic updates for instant UI feedback

### Developer Experience
- Single source of truth for data fetching
- Consistent patterns across entire app
- Query devtools for debugging
- Less boilerplate code

### Code Quality
- ~1,088 net lines removed
- Simpler mental model (no service layer)
- Better TypeScript inference
- Easier to test

### Architecture
- **100% TanStack Query coverage** - no service layer, no direct adapter
calls
- Clear separation: UI ← Queries/Mutations ← Adapters ← API
- Automatic cache management
- Consistent mutation patterns everywhere

## Testing

All features verified:
- Party creation (anonymous & authenticated)
- Grid operations (add, remove, update, swap, move)
- Party operations (update, delete, remix, favorite)
- Cache invalidation across tabs
- Error handling and rollback
- SSR with hydration

## Files Modified

### Created (3)
- `src/lib/types/party-context.ts`
- `src/lib/utils/editKeys.ts`
- `src/lib/utils/localId.ts`

### Deleted (4)
- `src/lib/services/party.service.ts`
- `src/lib/services/grid.service.ts`
- `src/lib/services/conflict.service.ts`
- `src/lib/utils/gridOperations.ts`

### Modified (13)
- `src/lib/api/mutations/grid.mutations.ts`
- `src/lib/components/grids/CharacterGrid.svelte`
- `src/lib/components/grids/SummonGrid.svelte`
- `src/lib/components/grids/WeaponGrid.svelte`
- `src/lib/components/party/Party.svelte`
- `src/routes/teams/new/+page.svelte`
- Database entity pages (characters, weapons, summons)
- Other supporting files

## Migration Complete

This PR completes the TanStack Query migration. The entire application
now uses TanStack Query v6 for all data fetching and mutations, with
zero remaining service layer code.

-## Migration Strategy
-
-### Key Changes Per File Type
-
-#### For API Resources:
-```typescript
-// Before
-import { buildUrl, get } from '$lib/api/core'
-const url = buildUrl('/parties')
-const res = await fetch(url)
-
-// After
-import { partyAdapter } from '$lib/api/adapters'
-const party = await partyAdapter.getByShortcode(shortcode)
-```
-
-#### For Services:
-```typescript
-// Before
-constructor(private fetch: FetchLike) {}
-
-// After
-constructor(private adapter: PartyAdapter) {}
-```
-
-#### For API Routes:
-```typescript
-// Before
-const response = await fetch(buildUrl(`/parties/${id}`))
-
-// After
-const party = await partyAdapter.getByShortcode(id)
-return json(party)
-```
-
-#### For Page Server Components:
-```typescript
-// Before
-import { get } from '$lib/api/core'
-const character = await get(fetch, `/characters/${id}`)
-
-// After
-import { entityAdapter } from '$lib/api/adapters'
-const character = await entityAdapter.getCharacter(id)
-```
-
-## Benefits
-1. **Type Safety**: Adapters provide strong typing for all operations
-2. **Consistency**: Unified API across all resource types
-3. **Error Handling**: Centralized error handling with proper types
-4. **Caching**: Built-in caching with TTL support
-5. **Transformation**: Automatic snake_case/camelCase conversion
-6. **Testing**: All adapters have comprehensive test coverage
-
-## Execution Order
-1. Start with Phase 1 (API Resources) as they're dependencies
-2. Move to Phase 2 (Services)
-3. Tackle Phase 3 (API Routes) in batches by resource type
-4. Complete Phase 4 (Page Server)
-5. Finish with Phase 5 (Utility files)
-
-This migration will be done incrementally, ensuring each phase is complete and tested before moving to the next.

-# API Adapter Architecture
-
-## Overview
-
-This document defines the adapter pattern implementation for the Hensei API layer. The adapter pattern provides a consistent interface for all API operations while handling transformations, error handling, caching, and reactive state management through Runed.
-
-## Current State Analysis
-
-### Existing API Structure
-```
-/lib/api/
-├── core.ts              # HTTP utilities (get, post, put, del)
-├── client.ts            # APIClient class with edit key management
-├── resources/           # Resource-specific functions
-│   ├── search.ts        # Search functions (weapons, characters, summons)
-│   ├── parties.ts       # Party CRUD operations
-│   ├── weapons.ts       # Weapon entity operations
-│   ├── characters.ts    # Character entity operations
-│   ├── summons.ts       # Summon entity operations
-│   └── grid.ts          # Grid management operations
-└── schemas/
-    ├── transforms.ts    # snake_case ↔ camelCase transformations
-    └── party.ts         # Zod schemas for validation
-```
-
-### Key Issues to Address
-1. **Inconsistent patterns**: Mix of functional and class-based approaches
-2. **Repeated logic**: Error handling, transformations duplicated across resources
-3. **Type safety gaps**: Some responses use `z.any()`, losing compile-time safety
-4. **No cancellation support**: Missing AbortController integration
-5. **No unified caching**: Each component manages its own caching logic
-6. **Complex transformations**: The "object" → entity renaming is manual and error-prone
-
-## Architecture Design
-
-### Layer Structure
-```

-│         UI Components               │

-└─────────────────────────────────────┘
-```
-
-### Core Concepts
-
-#### 1. Base Adapter
-All adapters extend from a base class that provides:
-- Response transformation (snake_case → camelCase)
-- Error normalization
-- Request cancellation
-- Performance timing
-- Debug logging
-
-#### 2. Resource Adapters
-Specialized adapters for each resource type:
-- **SearchAdapter**: Unified search interface
-- **PartyAdapter**: Party CRUD with edit key management
-- **GridAdapter**: Grid operations with optimistic updates
-- **EntityAdapter**: Characters, weapons, summons
-- **UserAdapter**: Authentication and profile management
-
-#### 3. Runed Integration
-Reactive resources using Runed utilities:
-- Automatic request cancellation
-- Debounced inputs
-- Loading states
-- Error recovery
-- Cache invalidation
-

-
-## Testing Methodology
-
-### Why Testing Matters for LLM Development
-When Claude Code implements adapters, we need immediate verification that the code works without manual component testing. This section provides comprehensive testing strategies.
-
-### Test Infrastructure Setup
-
-#### 1. Install Testing Dependencies
-```bash
-# These should already be installed, but verify:
-pnpm add -D vitest @vitest/ui msw @testing-library/svelte
-```
-
-#### 2. Test Configuration
-```typescript
-// vitest.config.adapter.ts
-import { defineConfig } from 'vitest/config'
-
-export default defineConfig({
-  test: {
-    name: 'adapters',
-    include: ['src/lib/api/adapters/**/*.test.ts'],
-    environment: 'node',
-    setupFiles: ['./src/lib/api/adapters/test-setup.ts'],
-    testTimeout: 5000
-  }
-})
-```
-
-#### 3. Mock Server Setup
-```typescript
-// src/lib/api/adapters/test-setup.ts
-import { setupServer } from 'msw/node'
-import { http, HttpResponse } from 'msw'
-import { beforeAll, afterAll, afterEach } from 'vitest'
-
-export const mockServer = setupServer()
-
-beforeAll(() => mockServer.listen({ onUnhandledRequest: 'error' }))
-afterEach(() => mockServer.resetHandlers())
-afterAll(() => mockServer.close())
-
-// Helper to add mock handlers
-export function mockAPI(path: string, response: any, status = 200) {
-  mockServer.use(
-    http.post(`*/api/v1${path}`, () => {
-      return HttpResponse.json(response, { status })
-    })
-  )
-}
-```
-
-### Test Categories
-
-#### 1. Unit Tests (Adapter Logic)
-Test adapters in isolation without real API calls.
-
-```typescript
-// src/lib/api/adapters/__tests__/base.adapter.test.ts
-import { describe, it, expect, vi } from 'vitest'
-import { BaseAdapter } from '../base.adapter'
-import { mockAPI } from '../test-setup'
-
-describe('BaseAdapter', () => {
-  it('should transform snake_case to camelCase', async () => {
-    mockAPI('/test', { user_name: 'test', created_at: '2024-01-01' })
-
-    const adapter = new BaseAdapter()
-    const result = await adapter.request('/test')
-
-    expect(result).toEqual({
-      userName: 'test',
-      createdAt: '2024-01-01'
-    })
-  })
-
-  it('should handle request cancellation', async () => {
-    const adapter = new BaseAdapter()
-    const controller = new AbortController()
-
-    const promise = adapter.request('/slow', { signal: controller.signal })
-    controller.abort()
-
-    await expect(promise).rejects.toThrow('AbortError')
-  })
-
-  it('should normalize error responses', async () => {
-    mockAPI('/error', { error: 'Invalid request' }, 400)
-
-    const adapter = new BaseAdapter()
-
-    await expect(adapter.request('/error')).rejects.toMatchObject({
-      code: 'BAD_REQUEST',
-      status: 400,
-      message: 'Invalid request'
-    })
-  })
-})
-```
-
-#### 2. Integration Tests (With Mock API)
-Test complete adapter flows with realistic responses.
-
-```typescript
-// src/lib/api/adapters/__tests__/search.adapter.test.ts
-import { describe, it, expect } from 'vitest'
-import { SearchAdapter } from '../search.adapter'
-import { mockAPI } from '../test-setup'
-import mockSearchResponse from '../__fixtures__/search-response.json'
-
-describe('SearchAdapter', () => {
-  it('should unify search responses across types', async () => {
-    mockAPI('/search/weapons', mockSearchResponse.weapons)
-    mockAPI('/search/characters', mockSearchResponse.characters)
-
-    const adapter = new SearchAdapter()
-
-    // Test weapon search
-    const weapons = await adapter.search({
-      type: 'weapon',
-      query: 'eternals',
-      filters: { element: [1, 2] }
-    })
-
-    expect(weapons).toMatchObject({
-      items: expect.arrayContaining([
-        expect.objectContaining({
-          id: expect.any(String),
-          name: expect.any(String),
-          type: 'weapon'
-        })
-      ]),
-      hasMore: expect.any(Boolean),
-      total: expect.any(Number)
-    })
-  })
-
-  it('should handle pagination correctly', async () => {
-    const adapter = new SearchAdapter()
-
-    // First page
-    mockAPI('/search/weapons', {
-      results: Array(20).fill({ id: '1' }),
-      total_pages: 3,
-      page: 1
-    })
-
-    const page1 = await adapter.search({ type: 'weapon', page: 1 })

-    expect(page3.hasMore).toBe(false)
-    expect(page3.nextCursor).toBeUndefined()
-  })
-})
-```
-
-#### 3. Contract Tests (Type Safety)
-Ensure adapter outputs match expected TypeScript types.
-
-```typescript
-// src/lib/api/adapters/__tests__/types.test.ts
-import { describe, it, expectTypeOf } from 'vitest'
-import type { SearchResult, PartyData } from '$lib/types'
-import { SearchAdapter, PartyAdapter } from '../index'
-
-describe('Adapter Type Contracts', () => {
-  it('SearchAdapter should return correct types', async () => {
-    const adapter = new SearchAdapter()
-    const result = await adapter.search({ type: 'weapon' })
-
-    expectTypeOf(result).toMatchTypeOf<{
-      items: SearchResult[]
-      total: number
-      hasMore: boolean
-      nextCursor?: number
-    }>()
-  })
-
-  it('PartyAdapter should return PartyData type', async () => {
-    const adapter = new PartyAdapter()
-    const result = await adapter.get('abc123')
-
-    expectTypeOf(result).toMatchTypeOf<PartyData>()
-  })
-})
-```
-
-#### 4. Runed Integration Tests
-Test reactive behavior with Runed utilities.
-
-```typescript
-// src/lib/api/adapters/__tests__/runed.test.ts
-import { describe, it, expect, vi } from 'vitest'
-import { createSearchResource } from '../resources/search.resource'
-import { tick } from 'svelte'
-
-describe('Runed Resource Integration', () => {
-  it('should debounce search input', async () => {
-    const searchFn = vi.fn()
-    const resource = createSearchResource('weapon', {
-      debounce: 100,
-      fetcher: searchFn
-    })
-
-    // Rapid input changes
-    resource.setQuery('a')
-    resource.setQuery('ab')
-    resource.setQuery('abc')
-
-    // Should not call immediately
-    expect(searchFn).not.toHaveBeenCalled()
-
-    // Wait for debounce
-    await new Promise(r => setTimeout(r, 150))
-
-    // Should call once with final value
-    expect(searchFn).toHaveBeenCalledOnce()
-    expect(searchFn).toHaveBeenCalledWith(
-      expect.objectContaining({ query: 'abc' })
-    )
-  })
-
-  it('should cancel previous requests', async () => {
-    const resource = createSearchResource('weapon')
-
-    // Start first search
-    const promise1 = resource.search('test1')
-
-    // Immediately start second search (should cancel first)
-    const promise2 = resource.search('test2')
-
-    // First should be cancelled
-    await expect(promise1).rejects.toThrow('AbortError')
-
-    // Second should complete
-    await expect(promise2).resolves.toBeDefined()
-  })
-})
-```

-  }
-}
-
-smokeTest()
-```
-
-### Testing Commands
-
-Add to package.json:
-```json
-{
-  "scripts": {
-    "test:adapters": "vitest run --config vitest.config.adapter.ts",
-    "test:adapters:watch": "vitest --config vitest.config.adapter.ts",
-    "test:adapters:ui": "vitest --ui --config vitest.config.adapter.ts",
-    "test:adapter:smoke": "node src/lib/api/adapters/smoke-test.js",
-    "test:adapter:types": "tsc --noEmit -p src/lib/api/adapters/tsconfig.json"
-  }
-}
-```
-
-### LLM Testing Workflow
-
-When implementing each adapter, follow this workflow:
-
-1. **Implement the adapter**
-2. **Run type checking**: `pnpm test:adapter:types`
-3. **Run unit tests**: `pnpm test:adapters -- search.adapter`
-4. **Run smoke tests**: `pnpm test:adapter:smoke`
-5. **Run all tests**: `pnpm test:adapters`
-
-Only proceed to the next adapter after all tests pass.
-

-- **Federation**: Multiple API backends
-
----
-
-## Migration Strategy
-
-### Step 1: Parallel Implementation
-Keep existing API functions working while building adapters:
-```typescript
-// Use adapter internally but maintain old interface
-export async function searchWeapons(params: SearchParams) {
-  const adapter = new SearchAdapter()
-  return adapter.search({ ...params, type: 'weapon' })
-}
-```
-
-### Step 2: Component Migration
-Update components one at a time:
-```svelte
-<!-- Old -->
-<script>
-import { searchWeapons } from '$lib/api/resources/search'
-const results = await searchWeapons({ query: 'sword' })
-</script>
-
-<!-- New -->
-<script>
-import { createSearchResource } from '$lib/api/adapters/resources'
-const search = createSearchResource('weapon')
-search.setQuery('sword')
-</script>
-```
-
-### Step 3: Deprecation
-Once all components migrated:
-1. Mark old functions as deprecated
-2. Add console warnings in development
-3. Update documentation
-4. Remove after grace period
-
----
-
-## Performance Considerations
-
-### Caching Strategy
-```typescript
-class CacheManager {
-  private cache = new Map<string, { data: any; expires: number }>()
-
-  set(key: string, data: any, ttl = 5 * 60 * 1000) {
-    this.cache.set(key, {
-      data,
-      expires: Date.now() + ttl
-    })
-  }
-
-  get(key: string) {
-    const entry = this.cache.get(key)
-    if (!entry) return null
-
-    if (Date.now() > entry.expires) {
-      this.cache.delete(key)
-      return null
-    }
-
-    return entry.data
-  }
-
-  clear(pattern?: string) {
-    if (pattern) {
-      for (const key of this.cache.keys()) {
-        if (key.includes(pattern)) {
-          this.cache.delete(key)
-        }
-      }
-    } else {
-      this.cache.clear()
-    }
-  }
-}
-```
-
-### Request Deduplication
-```typescript
-class RequestDeduplicator {
-  private pending = new Map<string, Promise<any>>()
-
-  async dedupe<T>(
-    key: string,
-    factory: () => Promise<T>
-  ): Promise<T> {
-    const existing = this.pending.get(key)
-    if (existing) return existing
-
-    const promise = factory().finally(() => {
-      this.pending.delete(key)
-    })
-
-    this.pending.set(key, promise)
-    return promise
-  }
-}
-```
-
----
-
-## LLM Implementation Instructions
-
-### For Claude Code
-
-When implementing adapters, follow this exact sequence:
-
-1. **Start with Base Adapter**
-   ```bash
-   # Create the file
-   touch src/lib/api/adapters/base.adapter.ts
-
-   # Implement the base adapter (copy from this doc)
-
-   # Create test file
-   touch src/lib/api/adapters/__tests__/base.adapter.test.ts
-
-   # Run tests
-   pnpm test:adapters -- base.adapter
-   ```
-
-2. **Verify Each Step**
-   - After implementing each adapter, run its tests
-   - Don't proceed until tests pass
-   - If tests fail, check error messages and fix
-
-3. **Common Pitfalls to Avoid**
-   - Don't forget to transform responses (snake_case → camelCase)
-   - Always handle request cancellation
-   - Store edit keys in localStorage for parties
-   - Clean up abort controllers after requests
-   - Use proper TypeScript types (avoid `any` where possible)
-
-4. **Testing Checklist**
-   ```bash
-   # Type checking
-   pnpm test:adapter:types
-
-   # Unit tests for specific adapter
-   pnpm test:adapters -- [adapter-name]
-
-   # Smoke tests
-   pnpm test:adapter:smoke
-
-   # All tests
-   pnpm test:adapters
-   ```
-
-5. **Debug Failed Tests**
-   - Check mock server handlers match expected endpoints
-   - Verify transformation logic is correct
-   - Ensure abort controllers are properly cleaned up
-   - Check that cache keys are consistent
-
-### Implementation Order
-
-1. **Phase 1**: Base infrastructure (1-2 hours)
-   - base.adapter.ts
-   - errors.ts
-   - types.ts
-   - Base tests
-
-2. **Phase 2**: Search adapter (1 hour)
-   - search.adapter.ts
-   - Search tests
-   - Mock data fixtures
-
-3. **Phase 3**: Party adapter (1-2 hours)
-   - party.adapter.ts
-   - Edit key management
-   - Party tests
-
-4. **Phase 4**: Runed resources (2 hours)
-   - search.resource.ts
-   - party.resource.ts
-   - Integration tests
-
-5. **Phase 5**: Additional adapters (as needed)
-   - grid.adapter.ts
-   - user.adapter.ts
-   - entity.adapter.ts
-
-### Verification Commands
-
-After implementing everything, run this verification sequence:
-
-```bash
-# Install dependencies
-pnpm add runed
-pnpm add -D msw @testing-library/svelte
-
-# Type checking
-pnpm test:adapter:types
-
-# Run all adapter tests
-pnpm test:adapters
-
-# Run smoke tests
-pnpm test:adapter:smoke
-
-# Check bundle size
-pnpm build
-ls -lh .svelte-kit/output/client/_app/immutable/chunks/
-```
-
----
-
-## Conclusion
-
-This adapter architecture provides:
-1. **Consistent API interface** across all resources
-2. **Testable code** with comprehensive test coverage
-3. **Type safety** with TypeScript
-4. **Reactive state management** with Runed
-5. **Progressive enhancement** - start simple, add complexity as needed
-
-The testing methodology ensures that LLM implementations can be verified immediately without manual component testing, providing confidence that the code works correctly before integration.
-
-Start with Phase 1 and progress through each phase only after tests pass. This incremental approach minimizes risk and ensures a solid foundation for future features.

-# API Refactoring Plan: Server-Side Only Architecture
-
-## Executive Summary
-This document outlines the plan to refactor all Rails API calls in the hensei-svelte application to be server-side only, resolving authentication issues and improving security.
-
-## Current Architecture Analysis
-
-### API Layer (`/lib/api/`)
-- **`core.ts`**: Basic fetch wrappers that accept a `FetchLike` function
-- **`resources/`**: API endpoint functions (parties, grid, search, etc.)
-- Functions accept `fetch` as a parameter to work both client and server-side
-
-### Service Layer (`/lib/services/`)
-- `PartyService`, `GridService`, `ConflictService`
-- Services accept `fetch` in constructor and use API resources
-- Currently used both client-side and server-side
-
-### Authentication
-- `hooks.server.ts` has `handleFetch` that adds Bearer token to server-side requests
-- Client-side calls don't have access to the httpOnly auth token
-- Edit keys for anonymous users are stored in localStorage (client-side)
-- This is causing the 401 Unauthorized errors
-
-## Problems with Current Approach
-
-1. **Direct client API calls bypass authentication** - The `/teams/new/+page.svelte` directly imports and uses `gridApi` functions
-2. **Security issue** - Client shouldn't directly call backend API
-3. **Inconsistent authentication** - Only server-side fetch has the Bearer token
-4. **Edit keys are client-side only** - Server can't access localStorage where edit keys are stored
-
-## Proposed Solution: Server-Side API Proxy Routes
-
-### Step 1: Create Generic API Proxy Routes
-
-Create server endpoints that mirror the Rails API structure:
-
-#### `/src/routes/api/parties/+server.ts`
-- POST: Create new party
-- Handles both authenticated and anonymous users
-
-#### `/src/routes/api/parties/[id]/+server.ts`
-- PUT: Update party details
-- DELETE: Delete party
-- Validates edit permissions (authenticated user or edit key)
-
-#### `/src/routes/api/parties/[id]/weapons/+server.ts`
-- POST: Add weapon to party
-- PUT: Update weapon in party
-- DELETE: Remove weapon from party
-
-#### `/src/routes/api/parties/[id]/summons/+server.ts`
-- POST: Add summon to party
-- PUT: Update summon in party
-- DELETE: Remove summon from party
-
-#### `/src/routes/api/parties/[id]/characters/+server.ts`
-- POST: Add character to party
-- PUT: Update character in party
-- DELETE: Remove character from party
-
-### Step 2: Handle Edit Keys Properly
-
-Since edit keys are in localStorage (client-side), we need to:
-1. Pass edit key as a header from client to our proxy endpoints
-2. Server proxy validates and forwards it to Rails API
-3. Structure: Client → SvelteKit Server (with edit key) → Rails API
-
-Example flow:
-
-```javascript
-// Client-side
-const editKey = localStorage.getItem(`edit_key_${party.shortcode}`)
-await fetch('/api/parties/123/weapons', {
-  method: 'POST',
-  headers: {
-    'X-Edit-Key': editKey,  // Pass to our server
-    'Content-Type': 'application/json'
-  },
-  body: JSON.stringify({...})
-})
-
-// Server-side proxy
-export async function POST({ request, params, fetch, locals }) {
-  const editKey = request.headers.get('X-Edit-Key')
-  const body = await request.json()
-
-  // Server's fetch automatically adds Bearer token via handleFetch
-  const response = await fetch(`${API_BASE}/weapons`, {
-    method: 'POST',
-    headers: {
-      'Content-Type': 'application/json',
-      ...(editKey ? { 'X-Edit-Key': editKey } : {})
-    },
-    body: JSON.stringify(body)
-  })
-
-  return response
-}
-```
-
-### Step 3: Create a Unified API Client
-
-Create `/src/lib/api/client.ts` that:
-- Works only on client-side
-- Automatically includes edit keys from localStorage
-- Calls our SvelteKit proxy endpoints (not Rails directly)
-- Can be used in both `/teams/new` and `/teams/[shortcode]`
-
-```typescript
-export class APIClient {
-  private getEditKey(partyId: string): string | null {
-    if (typeof window === 'undefined') return null
-    return localStorage.getItem(`edit_key_${partyId}`)
-  }
-
-  async addWeapon(partyId: string, weaponId: string, position: number, options?: any) {
-    const editKey = this.getEditKey(partyId)
-    const response = await fetch(`/api/parties/${partyId}/weapons`, {
-      method: 'POST',
-      headers: {
-        'Content-Type': 'application/json',
-        ...(editKey ? { 'X-Edit-Key': editKey } : {})
-      },
-      body: JSON.stringify({ weaponId, position, ...options })
-    })
-
-    if (!response.ok) throw new Error(`Failed to add weapon: ${response.statusText}`)
-    return response.json()
-  }
-
-  // Similar methods for other operations...
-}
-```
-
-### Step 4: Update Components
-
-#### `/routes/teams/new/+page.svelte`
-- Remove direct `gridApi` and `partiesApi` imports
-- Use the new `APIClient` class
-- Edit keys handled automatically by the client
-
-#### `/routes/teams/[shortcode]/+page.svelte` (via Party component)
-- Use the same `APIClient` for consistency
-- Edit keys retrieved from localStorage when needed
-
-#### Services (`PartyService`, `GridService`)
-- Keep them server-side only
-- Used in `+page.server.ts` files
-- Client components use `APIClient` instead
-
-### Step 5: Authentication Flow
-
-#### Authenticated Users
-1. Client → SvelteKit Server (no edit key needed)
-2. SvelteKit Server → Rails API (with Bearer token from cookies)
-
-#### Anonymous Users
-1. Client → SvelteKit Server (with edit key from localStorage)
-2. SvelteKit Server → Rails API (with edit key header)
-
-## Benefits of This Approach
-
-1. **Single API interface** - Same `APIClient` works for both new and existing parties
-2. **Proper authentication** - Server-side requests include Bearer token
-3. **Edit key support** - Anonymous users can still edit their parties
-4. **Security** - Rails API never exposed to client
-5. **Reusability** - Same code paths for `/teams/new` and `/teams/[shortcode]`
-6. **Progressive enhancement** - Can still use form actions where appropriate
-
-## Implementation Order
-
-1. Create the API proxy routes in `/src/routes/api/`
-2. Create the `APIClient` class
-3. Update `/routes/teams/new/+page.svelte` to use `APIClient`
-4. Update Party component to use `APIClient` for grid operations
-5. Test both authenticated and anonymous user flows
-6. Remove direct API imports from client components
-
-## Testing Checklist
-
-### Authenticated User Flow
-- [ ] Can create new party
-- [ ] Can add weapons/summons/characters to new party
-- [ ] Can edit existing party they own
-- [ ] Cannot edit party they don't own
-
-### Anonymous User Flow
-- [ ] Can create new party (receives edit key)
-- [ ] Can add items to party using edit key
-- [ ] Can edit party after page refresh (edit key persists)
-- [ ] Cannot edit without valid edit key
-
-### Error Handling
-- [ ] 401 errors properly handled
-- [ ] Network errors display user-friendly messages
-- [ ] Invalid data errors show validation messages
-
-## Migration Path
-
-This refactor can be done incrementally:
-1. Start with new proxy routes (doesn't break existing code)
-2. Update one component at a time to use new API client
-3. Gradually remove direct API imports
-4. Finally remove unused code
-
-## Notes
-
-- The `account` cookie is httpOnly for security, which is why we need server-side proxy
-- Edit keys must be passed from client since they're in localStorage
-- All Rails API endpoints should remain unchanged
-- This architecture follows SvelteKit best practices for API integration

-# Clean Architecture Plan: Type-Safe Data Flow with Single Source of Truth
-
-## Analysis Summary
-
-After examining the Rails blueprints and current implementation, I've identified the key issues:
-
-1. **Type Redundancy**: We have multiple types for the same entities (Party vs PartyView, GridWeapon vs GridWeaponItemView)
-2. **Inconsistent Naming**: The API uses `object` to refer to nested entities (weapon, character, summon)
-3. **Complex Validation**: The parseParty function does too much transformation and validation
-4. **Hydration Issues**: Server and client compute different values due to timing and data availability
-
-## Proposed Architecture
-
-### 1. Single Source of Truth for Types
-
-Create clean, single type definitions based on the Rails blueprints:
-
-```typescript
-// Core entities (from blueprints)
-interface Weapon {
-  id: string
-  granblueId: string
-  name: LocalizedName
-  element: number
-  proficiency: number
-  rarity: number
-  // ... all fields from WeaponBlueprint
-}
-
-interface Character {
-  id: string
-  granblueId: string
-  name: LocalizedName
-  element: number
-  rarity: number
-  // ... all fields from CharacterBlueprint
-}
-
-interface Summon {
-  id: string
-  granblueId: string
-  name: LocalizedName
-  element: number
-  rarity: number
-  // ... all fields from SummonBlueprint
-}
-
-// Grid items (relationships)
-interface GridWeapon {
-  id: string
-  position: number
-  mainhand?: boolean
-  uncapLevel?: number
-  transcendenceStep?: number
-  element?: number
-  weapon: Weapon  // Named properly, not "object"
-  weaponKeys?: WeaponKey[]
-  // ... fields from GridWeaponBlueprint
-}
-
-interface GridCharacter {
-  id: string
-  position: number
-  uncapLevel?: number
-  perpetuity?: boolean
-  transcendenceStep?: number
-  character: Character  // Named properly, not "object"
-  awakening?: Awakening
-  // ... fields from GridCharacterBlueprint
-}
-
-interface GridSummon {
-  id: string
-  position: number
-  main?: boolean
-  friend?: boolean
-  quickSummon?: boolean
-  uncapLevel?: number
-  summon: Summon  // Named properly, not "object"
-  // ... fields from GridSummonBlueprint
-}
-
-interface Party {
-  id: string
-  shortcode: string
-  name?: string
-  description?: string
-  weapons: GridWeapon[]
-  characters: GridCharacter[]
-  summons: GridSummon[]
-  job?: Job
-  raid?: Raid
-  // ... all fields from PartyBlueprint
-}
-```
-
-### 2. Automatic Case Transformation Layer
-
-Create a type-safe API client that handles transformations automatically:
-
-```typescript
-// api/client.ts
-class ApiClient {
-  private transformResponse<T>(data: any): T {
-    // Transform snake_case to camelCase
-    const camelCased = snakeToCamel(data)
-
-    // Rename "object" to proper entity names
-    if (camelCased.weapons) {
-      camelCased.weapons = camelCased.weapons.map(w => ({
-        ...w,
-        weapon: w.object,
-        object: undefined
-      }))
-    }
-    if (camelCased.characters) {
-      camelCased.characters = camelCased.characters.map(c => ({
-        ...c,
-        character: c.object,
-        object: undefined
-      }))
-    }
-    if (camelCased.summons) {
-      camelCased.summons = camelCased.summons.map(s => ({
-        ...s,
-        summon: s.object,
-        object: undefined
-      }))
-    }
-
-    return camelCased as T
-  }
-
-  private transformRequest<T>(data: T): any {
-    // Transform camelCase to snake_case
-    // Rename entity names back to "object" for API
-    const prepared = {
-      ...data,
-      weapons: data.weapons?.map(w => ({
-        ...w,
-        object: w.weapon,
-        weapon: undefined
-      })),
-      // Similar for characters and summons
-    }
-
-    return camelToSnake(prepared)
-  }
-
-  async get<T>(path: string): Promise<T> {
-    const response = await fetch(path)
-    const data = await response.json()
-    return this.transformResponse<T>(data)
-  }
-
-  async post<T>(path: string, body: any): Promise<T> {
-    const response = await fetch(path, {
-      body: JSON.stringify(this.transformRequest(body))
-    })
-    const data = await response.json()
-    return this.transformResponse<T>(data)
-  }
-}
-```
-
-### 3. Service Layer
-
-Create clean service interfaces that return properly typed data:
-
-```typescript
-// services/party.service.ts
-export class PartyService {
-  constructor(private client: ApiClient) {}
-
-  async getByShortcode(shortcode: string): Promise<Party> {
-    // Client handles all transformations
-    return this.client.get<Party>(`/parties/${shortcode}`)
-  }
-
-  async update(id: string, updates: Partial<Party>): Promise<Party> {
-    return this.client.put<Party>(`/parties/${id}`, updates)
-  }
-}
-```
-
-### 4. Component Updates
-
-Components use the clean, properly typed interfaces:
-
-```typescript
-// Party.svelte
-interface Props {
-  initial: Party  // Single Party type, no confusion
-}
-
-// WeaponUnit.svelte
-interface Props {
-  item: GridWeapon  // Properly typed with weapon property
-}
-
-// Access data cleanly:
-const imageUrl = item.weapon.granblueId
-const name = item.weapon.name
-```
-
-## Implementation Steps
-
-1. **Create new type definitions** in `/src/lib/types/`:
-   - `entities.ts` - Core entities (Weapon, Character, Summon, etc.)
-   - `grid.ts` - Grid items (GridWeapon, GridCharacter, GridSummon)
-   - `party.ts` - Party and related types
-
-2. **Update API client** in `/src/lib/api/`:
-   - Add transformation logic to handle `object` → entity name mapping
-   - Keep snake_case/camelCase transformation
-   - Make it type-safe with generics
-
-3. **Simplify parseParty**:
-   - Remove validation schemas
-   - Just call the API client's transform method
-   - Trust the API data structure
-
-4. **Update components**:
-   - Use the new single types everywhere
-   - Access `item.weapon.granblueId` instead of `item.object.granblueId`
-   - Remove all the `as any` casts
-
-5. **Remove redundant types**:
-   - Delete PartyView, GridWeaponItemView, etc.
-   - Use only the new clean types
-
-## Benefits
-
-✅ **Single source of truth** - One type per entity, no confusion
-✅ **Type safety** - Full TypeScript benefits with proper types
-✅ **Clean property names** - `weapon`, `character`, `summon` instead of `object`
-✅ **Automatic transformations** - Handle case conversion in one place
-✅ **No hydration issues** - Consistent data structure everywhere
-✅ **Maintainable** - Clear separation of concerns
-✅ **Future-proof** - Easy to add new entities or fields

-# Database Detail Pages Refactor Plan (SvelteKit-centric)
-
-This plan refactors the database detail pages to be modular, reusable, and easy to port across characters, weapons, and summons. It leans into SvelteKit features (server `load`, form `actions`, and `use:enhance`) and Svelte composition (slots, small components, and lightweight state helpers).
-
-## Goals
-- Consistent scaffold for detail pages (header, edit toolbar, sections, feedback).
-- Encapsulated edit-mode state + mapping to/from API payloads.
-- Clean separation between server concerns (loading, saving, validation) and client UI.
-- Reusable section components that can be shared or adapted per resource.
-- Smooth path to port the architecture to weapons and summons.
-
-## Architecture Overview
-- Client
-  - `DetailScaffold.svelte`: Common header, edit/save/cancel controls, messages, and section slots.
-  - `createEditForm.ts`: Small factory returning state + helpers for edit lifecycle.
-    - Initializes `editData` from the resource model via a schema mapping.
-    - Exposes `editMode`, `toggleEdit`, `reset`, `set`, `get`, and `submit` glue for forms.
-  - `image.ts`: `getResourceImage(type, granblue_id)` centralizing image paths and fallbacks.
-  - Section components per resource (e.g., `CharacterMetadataSection.svelte`, shared `StatsSection` when possible).
-- Server
-  - Shared loader helpers (e.g., `lib/server/detail/load.ts`) to fetch a resource detail and normalize to a client-facing model.
-  - Form actions in `+page.server.ts` for save (`actions.save`) with validation (optionally Zod) and proper error handling.
-  - Progressive enhancement via `use:enhance` so the UI stays responsive without losing SSR form semantics.
-- Schema-driven mapping
-  - Per resource (`characters/schema.ts`, `weapons/schema.ts`, `summons/schema.ts`) define:
-    - `toEditData(model)`: API model -> UI edit state.
-    - `toPayload(editData)`: UI edit state -> API payload.
-    - Optional field metadata (labels, formatter hooks) for low-ceremony sections.
-
-## File Structure (proposed)
-- `src/lib/features/database/detail/`
-  - `DetailScaffold.svelte` (header + actions + slots)
-  - `createEditForm.ts` (state helper)
-  - `image.ts` (resource image helper)
-  - `api.ts` (client-side action helpers if needed)
-- `src/lib/features/database/characters/`
-  - `schema.ts`
-  - `sections/`
-    - `CharacterMetadataSection.svelte`
-    - `CharacterUncapSection.svelte`
-    - `CharacterTaxonomySection.svelte`
-    - `CharacterStatsSection.svelte`
-      - `HPStatsSubsection.svelte`
-      - `ATKStatsSubsection.svelte`
-- Similar folders for `weapons` and `summons` as we port.
-
-## Form Actions and Loaders
-- Loader strategy
-  - Current route `+page.ts`/`+page.server.ts` fetches the detailed entity and returns a normalized `model`.
-  - A shared helper `getResourceDetail(resource, id)` can live under `lib/server/detail/load.ts` to reduce duplication across resources.
-- Save strategy
-  - Define `export const actions = { save: async (event) => { ... } }` in `+page.server.ts`.
-  - Validate incoming form data (Zod/schema), map to API payload via the schema’s `toPayload`, then persist via your backend API.
-  - Return `fail(status, { fieldErrors, message })` on validation errors.
-  - On success, return the updated item; `load` can pick it up or the client can reconcile locally.
-- Client strategy
-  - Wrap the editable fields in a `<form method="POST">` with `use:enhance`.
-  - For a gradual migration from controlled inputs, keep local `editData` but mirror it into form fields (hidden or direct binds) to submit via actions.
-  - Use action results to show success/error messages in `DetailScaffold`.
-
-## Phased Tasks
-
-### Phase 1 — Extract Scaffold + Edit Form Helper
-- [ ] Create `src/lib/features/database/detail/DetailScaffold.svelte` with slots:
-  - [ ] Header slot or props for resource `type`, `item`, `image`.
-  - [ ] Top-right action area for Edit/Cancel/Save.
-  - [ ] Message area for success/error.
-  - [ ] Default slot for sections.
-- [ ] Create `src/lib/features/database/detail/createEditForm.ts`:
-  - [ ] Accepts initial `model` and mapping `toEditData`/`toPayload`.
-  - [ ] Returns `editMode`, `editData` (store or bindable object), `toggleEdit`, `reset`, `submit`.
-  - [ ] Resets `editData` when `model` changes.
-- [ ] Replace inline header/controls in `characters/[id]/+page.svelte` with `DetailScaffold` while preserving behavior.
-
-### Phase 2 — Extract Character Sections
-- [ ] `CharacterMetadataSection.svelte` (Rarity, Granblue ID): view/edit with existing utilities.
-- [ ] `CharacterUncapSection.svelte` (Indicator + FLB/ULB/Transcendence/Special toggles).
-- [ ] `CharacterTaxonomySection.svelte` (Element, Race1/2, Gender, Proficiency1/2).
-- [ ] `CharacterStatsSection.svelte` with subcomponents for HP and ATK stats.
-- [ ] Wire sections to `editMode` and `editData` via props/bindings; keep look-and-feel identical.
-
-### Phase 3 — Add Schema + Validation + Actions
-- [ ] `src/lib/features/database/characters/schema.ts`:
-  - [ ] `toEditData(model)` maps current character model to edit state.
-  - [ ] `toPayload(editData)` maps edit state to backend payload.
-  - [ ] Optional Zod schemas for validation.
-- [ ] Add `+page.server.ts` `actions.save` for characters:
-  - [ ] Parse form data; validate; call backend; return updated item or errors.
-  - [ ] Handle cookies/credentials as needed.
-- [ ] Wrap editable UI in `<form method="POST" use:enhance>` and handle optimistic UI/disable Save while pending.
-- [ ] Show validation errors and success states in `DetailScaffold`.
-
-### Phase 4 — Shared Loaders + Port to Weapons/Summons
-- [ ] Add `lib/server/detail/load.ts` helpers for shared resource fetching.
-- [ ] Update characters loader to use shared helper.
-- [ ] Create `src/lib/features/database/weapons/schema.ts` and sections; adopt the scaffold.
-- [ ] Create `src/lib/features/database/summons/schema.ts` and sections; adopt the scaffold.
-- [ ] Implement `+page.server.ts` actions for weapons and summons with validation.
-
-### Phase 5 — Polish and DX
-- [ ] `image.ts` helper and replace ad-hoc image path logic.
-- [ ] Extract `getDisplayName` to a single utility.
-- [ ] Add unit tests for schema mapping functions (to/from payload).
-- [ ] Add basic e2e smoke for actions (save success and validation failure).
-- [ ] Document conventions (where to put schemas, sections, and loaders).
-
-## Acceptance Criteria
-- Character detail page renders identically, with no regressions.
-- Edit mode and saving function via form actions, with graceful errors.
-- Sections are split into components and trivially testable.
-- Weapons and summons can be implemented by adding schema + sections and wiring the same scaffold and actions.
-
-## Risks and Mitigations
-- Form action migration conflict with controlled inputs:
-  - Mitigate by mirroring `editData` into form fields and using `use:enhance` to reconcile results.
-- Server validation shape mismatch:
-  - Use Zod schemas that align with backend; log/trace action failures early.
-- Over-abstracting sections:
-  - Favor small, explicit components; introduce config-driven rendering only where repetition is high and behavior simple.
-
----
-
-If we agree on this plan, start with Phase 1 (scaffold + helper) and wire it into the character page without changing behavior, then proceed section-by-section.

-# DetailsSidebar Segmented Control Implementation
-
-## Overview
-
-Add a segmented control to the DetailsSidebar component that allows users to switch between viewing the canonical (base) item data and the user's customized version with their modifications.
-
-## User Requirements
-
-The sidebar should display two distinct views:
-
-1. **Canonical Data View** - Shows the base item statistics and properties as they exist in the game database
-2. **User Version View** - Shows the user's specific customizations and modifications to the item
-
-## Data Structure Analysis
-
-### Current Grid Item Structure
-
-Each grid item (GridCharacter, GridWeapon, GridSummon) contains:
-- The base object data (`character`, `weapon`, or `summon`)
-- User-specific modifications stored at the grid item level
-- Instance-specific properties like position, uncap level, etc.
-
-### User Version Data by Type
-
-#### Weapons (GridWeapon)
-- `uncapLevel` - Current uncap level (0-6)
-- `transcendenceStep` - Transcendence stage (0-5)
-- `awakening` - Object containing:
-  - `type` - Awakening type with name and slug
-  - `level` - Awakening level
-- `weaponKeys` - Array of weapon keys:
-  - Opus pendulums (series 2)
-  - Draconic telumas (series 3, 34)
-  - Ultima gauph keys (series 17)
-  - Revans emblems (series 22)
-- `ax` - Array of AX skills containing:
-  - `modifier` - Skill ID
-  - `strength` - Skill strength value
-- `element` - Instance element for null-element weapons
-
-#### Characters (GridCharacter)
-- `uncapLevel` - Current uncap level (0-5 or 0-6)
-- `transcendenceStep` - Transcendence stage (0-5)
-- `awakening` - Awakening type and level
-- `rings` - Array of over mastery rings:
-  - `modifier` - Ring stat type
-  - `strength` - Ring stat value
-- `earring` - Aetherial mastery object:
-  - `modifier` - Earring stat type
-  - `strength` - Earring stat value
-- `aetherial_mastery` - Alternative property name for earring
-- `perpetuity` - Boolean for permanent mastery status
-
-#### Summons (GridSummon)
-- `uncapLevel` - Current uncap level (0-5)
-- `transcendenceStep` - Transcendence stage (0-5)
-- `quick_summon` - Boolean for quick summon status
-- `friend` - Boolean for friend summon
-
-## Component Architecture
-
-### Reusable Components to Create
-
-#### 1. `DetailsSidebarSegmentedControl.svelte`
-A specialized segmented control for the details sidebar that can be reused across different detail views.
-
-```svelte
-<script lang="ts">
-  interface Props {
-    hasModifications: boolean
-    selectedView: 'canonical' | 'user'
-    onViewChange: (view: 'canonical' | 'user') => void
-  }
-</script>
-```
-
-#### 2. `ModificationSection.svelte`
-Generic wrapper for modification sections with consistent styling.
-
-```svelte
-<script lang="ts">
-  interface Props {
-    title: string
-    visible?: boolean
-    children: Snippet
-  }
-</script>
-
-{#if visible}
-  <div class="modification-section">
-    <h3>{title}</h3>
-    <div class="modification-content">
-      {@render children()}
-    </div>
-  </div>
-{/if}
-```
-
-#### 3. `AwakeningDisplay.svelte`
-Reusable awakening display component for both weapons and characters.
-
-```svelte
-<script lang="ts">
-  import { getAwakeningImage } from '$lib/utils/modifiers'
-
-  interface Props {
-    awakening?: { type: Awakening; level: number }
-    size?: 'small' | 'medium' | 'large'
-    showLevel?: boolean
-  }
-</script>
-```
-
-#### 4. `WeaponKeysList.svelte`
-Component for displaying weapon keys with proper icons and formatting.
-
-```svelte
-<script lang="ts">
-  import { getWeaponKeyImages } from '$lib/utils/modifiers'
-
-  interface Props {
-    weaponKeys?: WeaponKey[]
-    weaponData: { element?: number; proficiency?: number; series?: number; name?: LocalizedString }
-    layout?: 'list' | 'grid'
-  }
-</script>
-```
-
-#### 5. `StatModifierItem.svelte`
-Generic component for displaying stat modifications (rings, earrings, etc.).
-
-```svelte
-<script lang="ts">
-  interface Props {
-    label: string
-    value: string | number
-    suffix?: string
-    icon?: string
-    variant?: 'default' | 'enhanced' | 'max'
-  }
-</script>
-
-<div class="stat-modifier" class:variant>
-  {#if icon}<img src={icon} alt="" />{/if}
-  <span class="label">{label}</span>
-  <span class="value">{value}{suffix}</span>
-</div>
-```
-
-#### 6. `UncapStatusDisplay.svelte`
-Dedicated component for showing current uncap/transcendence status.
-
-```svelte
-<script lang="ts">
-  interface Props {
-    type: 'character' | 'weapon' | 'summon'
-    uncapLevel?: number
-    transcendenceStep?: number
-    maxUncap: number
-    showIndicator?: boolean
-  }
-</script>
-```
-
-### Data Processing Utilities
-
-#### `modificationDetector.ts`
-Utility to detect what modifications exist on a grid item.
-
-```typescript
-export interface ModificationStatus {
-  hasModifications: boolean
-  hasAwakening: boolean
-  hasWeaponKeys: boolean
-  hasAxSkills: boolean
-  hasRings: boolean
-  hasEarring: boolean
-  hasPerpetuity: boolean
-  hasTranscendence: boolean
-}
-
-export function detectModifications(
-  type: 'character' | 'weapon' | 'summon',
-  item: GridCharacter | GridWeapon | GridSummon
-): ModificationStatus {
-  // Implementation
-}
-```
-
-#### `modificationFormatters.ts`
-Centralized formatters for modification display.
-
-```typescript
-export function formatRingStat(modifier: number, strength: number): string
-export function formatEarringStat(modifier: number, strength: number): string
-export function formatAxSkill(ax: SimpleAxSkill): string
-export function getWeaponKeyTitle(series?: number): string
-```
-
-### Component Composition Pattern
-
-The main DetailsSidebar will compose these smaller components:
-
-```svelte
-<!-- DetailsSidebar.svelte -->
-<DetailsSidebarSegmentedControl {hasModifications} bind:selectedView />
-
-{#if selectedView === 'canonical'}
-  <!-- Existing canonical view -->
-{:else}
-  <!-- User version composed of reusable components -->
-  <UncapStatusDisplay {type} {uncapLevel} {transcendenceStep} />
-
-  <ModificationSection title="Awakening" visible={item.awakening}>
-    <AwakeningDisplay awakening={item.awakening} size="medium" showLevel />
-  </ModificationSection>
-
-  {#if type === 'weapon'}
-    <ModificationSection title={getWeaponKeyTitle(item.weapon?.series)} visible={item.weaponKeys?.length}>
-      <WeaponKeysList {weaponKeys} weaponData={item.weapon} />
-    </ModificationSection>
-  {/if}
-
-  <!-- etc... -->
-{/if}
-```
-
-## Styling Guidelines
-
-### IMPORTANT: Use Existing Theme System
-
-**DO NOT create new style variables or custom styles.** All necessary styling is already defined in the theme files:
-
-- `_colors.scss` - All color variables and element-specific colors
-- `_typography.scss` - Font sizes, weights, and text styling
-- `_spacing.scss` - Spacing units and gaps
-- `_layout.scss` - Border radius, corners, and layout constants
-- `_effects.scss` - Shadows, transitions, and visual effects
-- `_mixins.scss` - Reusable style mixins
-- `_rep.scss` - Representation/aspect ratio utilities
-
-### Component Styling Example
-
-```scss
-// Import only what's needed from themes
-@use '$src/themes/colors' as colors;
-@use '$src/themes/typography' as typography;
-@use '$src/themes/spacing' as spacing;
-@use '$src/themes/layout' as layout;
-@use '$src/themes/effects' as effects;
-
-.modification-section {
-  // Use existing spacing variables
-  margin-bottom: spacing.$unit-3x;
-  padding: spacing.$unit-2x;
-
-  h3 {
-    // Use existing typography
-    font-size: typography.$font-regular;
-    font-weight: typography.$medium;
-    color: var(--text-secondary, colors.$grey-40);
-    margin-bottom: spacing.$unit-1-5x;
-  }
-}
-
-.stat-modifier {
-  // Use existing layout patterns
-  display: flex;
-  justify-content: space-between;
-  padding: spacing.$unit;
-  background: colors.$grey-90;
-  border-radius: layout.$item-corner-small;
-
-  .label {
-    font-size: typography.$font-small;
-    color: var(--text-secondary, colors.$grey-50);
-  }
-
-  .value {
-    font-size: typography.$font-regular;
-    font-weight: typography.$medium;
-    color: var(--text-primary, colors.$grey-10);
-  }
-
-  // Use existing effect patterns for enhanced state
-  &.enhanced {
-    background: colors.$grey-85;
-    box-shadow: effects.$hover-shadow;
-  }
-}
-
-.awakening-display {
-  // Use consistent spacing
-  display: flex;
-  gap: spacing.$unit-2x;
-  align-items: center;
-
-  img {
-    // Use standard sizing
-    width: spacing.$unit-6x;
-    height: spacing.$unit-6x;
-    border-radius: layout.$item-corner-small;
-  }
-}
-```
-
-### Theme Variables Reference
-
-#### Colors
-- Text: `var(--text-primary)`, `var(--text-secondary)`, `var(--text-tertiary)`
-- Backgrounds: `var(--card-bg)`, `colors.$grey-90`, `colors.$grey-85`
-- Element colors: `var(--wind-item-detail-bg)`, etc.
-- State colors: `var(--color-success)`, `var(--color-error)`
-
-#### Typography
-- Sizes: `$font-tiny`, `$font-small`, `$font-regular`, `$font-medium`, `$font-large`
-- Weights: `$normal: 400`, `$medium: 500`, `$bold: 600`
-
-#### Spacing
-- Base unit: `$unit: 8px`
-- Multipliers: `$unit-half`, `$unit-2x`, `$unit-3x`, `$unit-4x`, etc.
-- Fractions: `$unit-fourth`, `$unit-third`
-
-#### Layout
-- Corners: `$item-corner`, `$item-corner-small`, `$modal-corner`
-- Breakpoints: Use mixins from `_mixins.scss`
-
-#### Effects
-- Shadows: `$hover-shadow`, `$focus-shadow`
-- Transitions: `$duration-zoom`, `$duration-color-fade`
-- Transforms: `$scale-wide`, `$scale-tall`
-
-## Benefits of Componentization
-
-### Maintainability
-- Each component has a single responsibility
-- Changes to display logic are isolated
-- Easier to test individual components
-- Consistent styling through shared theme system
-
-### Reusability
-- `AwakeningDisplay` can be used in hovercards, modals, and sidebars
-- `StatModifierItem` works for any stat modification
-- `ModificationSection` provides consistent section layout
-
-### Type Safety
-- Each component has clearly defined props
-- TypeScript interfaces ensure correct data flow
-- Compile-time checking prevents runtime errors
-
-### Performance
-- Components can be memoized if needed
-- Smaller components = smaller re-render boundaries
-- Derived states prevent unnecessary recalculation
-
-## Testing Strategy
-
-### Unit Tests for Components
-Each reusable component should have tests for:
-- Rendering with different prop combinations
-- Conditional visibility
-- Event handling
-- Edge cases (missing data, invalid values)
-
-### Integration Tests
-Test the complete DetailsSidebar with:
-- View switching
-- Data flow between components
-- Correct component composition
-
-### Visual Regression Tests
-Use Storybook to document and test visual states:
-- Different modification combinations
-- Various item types
-- Empty states
-- Loading states
-
-## Implementation Checklist
-
-### Phase 1: Infrastructure
-- [ ] Set up modificationDetector utility
-- [ ] Set up modificationFormatters utility
-- [ ] Create ModificationSection wrapper component
-
-### Phase 2: Display Components
-- [ ] Create AwakeningDisplay component
-- [ ] Create WeaponKeysList component
-- [ ] Create StatModifierItem component
-- [ ] Create UncapStatusDisplay component
-- [ ] Create DetailsSidebarSegmentedControl
-
-### Phase 3: Integration
-- [ ] Update DetailsSidebar to use new components
-- [ ] Wire up view switching logic
-- [ ] Implement canonical view with existing code
-- [ ] Implement user version view with new components
-
-### Phase 4: Polish
-- [ ] Add loading states
-- [ ] Add empty states
-- [ ] Optimize performance
-- [ ] Add accessibility attributes
-- [ ] Documentation and examples
-
-## Notes
-
-- Components should accept `class` prop for custom styling
-- All components should handle missing/null data gracefully
-- Consider using slots/snippets for maximum flexibility
-- Keep components pure - no direct API calls
-- Use consistent prop naming across components
-- **Always use existing theme variables - never create custom styles**
-- Import only the theme modules you need to minimize bundle size
-- Use CSS custom properties (var()) for dynamic theming support

-# Direct API Architecture Plan v2
-
-## Executive Summary
-
-This document outlines a comprehensive plan to migrate from proxy-endpoint-based API calls to direct API calls in the Hensei SvelteKit application, with proper token lifecycle management, SSR support, and security hardening.
-
-### Key Improvements in v2
-- **Token Bootstrap**: Proper SSR token initialization via hooks and layout
-- **Refresh Logic**: Single in-flight refresh with proper gating
-- **Security**: CSP, short TTL tokens, proper CORS configuration
-- **DX**: TanStack Query integration, proper error handling
-
-## Architecture Overview
-
-### Token Flow
-```
-1. Initial Load (SSR):
-   hooks.server.ts → Read refresh cookie → Exchange for access token → Pass to client
-
-2. Client Hydration:
-   +layout.svelte → Receive token from SSR → Initialize auth store
-
-3. API Calls:
-   Adapter → Check token expiry → Use token or refresh → Retry on 401
-
-4. Token Refresh:
-   Single in-flight promise → Exchange refresh token → Update store
-```
-
-## Implementation Plan
-
-### Phase 1: Core Authentication Infrastructure
-
-#### 1.1 Auth Store with Refresh Management
-`/src/lib/stores/auth.store.ts`:
-```typescript
-import { writable, get } from 'svelte/store'
-import { goto } from '$app/navigation'
-import { PUBLIC_SIERO_API_URL } from '$env/static/public'
-
-interface AuthState {
-  accessToken: string | null
-  user: UserInfo | null
-  expiresAt: Date | null
-  refreshPromise: Promise<boolean> | null
-}
-
-function createAuthStore() {
-  const { subscribe, set, update } = writable<AuthState>({
-    accessToken: null,
-    user: null,
-    expiresAt: null,
-    refreshPromise: null
-  })
-
-  const API = `${PUBLIC_SIERO_API_URL ?? 'http://localhost:3000'}/api/v1`
-
-  return {
-    subscribe,
-
-    setAuth: (token: string, user: UserInfo, expiresAt: Date) => {
-      set({
-        accessToken: token,

-
-### Phase 4: Fix Grid Adapter
-
-#### 4.1 Corrected Grid Adapter Methods
-`/src/lib/api/adapters/grid.adapter.ts` (key fixes):
-```typescript
-// Fix DELETE to include ID
-async deleteWeapon(id: string): Promise<void> {
-  return this.request<void>(`/grid_weapons/${id}`, {
-    method: 'DELETE'
-  })
-}
-
-// Fix position update URL
-async updateWeaponPosition(params: UpdatePositionParams): Promise<GridWeapon> {
-  const { id, position, container } = params
-  return this.request<GridWeapon>(`/grid_weapons/${id}/update_position`, {
-    method: 'POST',
-    body: { position, container }
-  })
-}
-
-// Fix swap URL (no partyId in path)
-async swapWeapons(params: SwapPositionsParams): Promise<{
-  source: GridWeapon
-  target: GridWeapon
-}> {
-  return this.request('/grid_weapons/swap', {
-    method: 'POST',
-    body: params
-  })
-}
-
-// Apply same patterns to characters and summons...
-```
-
-### Phase 5: Rails Configuration
-
-#### 5.1 Update CORS Configuration
-`config/initializers/cors.rb`:
-```ruby
-Rails.application.config.middleware.insert_before 0, Rack::Cors do
-  allow do
-    origins(
-      Rails.env.production? ?
-        ['https://app.hensei.dev', 'https://hensei.dev'] :
-        ['http://localhost:5173', 'http://localhost:5174', 'http://127.0.0.1:5173']
-    )
-
-    resource '/api/*',
-      headers: %w[Accept Authorization Content-Type X-Edit-Key],
-      expose: %w[X-RateLimit-Limit X-RateLimit-Remaining X-RateLimit-Reset],
-      methods: %i[get post put patch delete options head],
-      credentials: true,
-      max_age: 86400
-  end
-end
-```
-
-#### 5.2 Add Bootstrap Endpoint
-`app/controllers/api/v1/auth_controller.rb`:
-```ruby
-def bootstrap
-  # This is called by hooks.server.ts with refresh token in cookie
-  refresh_token = cookies[:refresh_token]
-
-  if refresh_token.blank?
-    render json: { error: 'No refresh token' }, status: :unauthorized
-    return
-  end
-
-  # Use Doorkeeper to validate and exchange
-  token = Doorkeeper::AccessToken.by_refresh_token(refresh_token)
-
-  if token.nil? || token.revoked?
-    render json: { error: 'Invalid refresh token' }, status: :unauthorized
-    return
-  end
-
-  # Create new access token
-  new_token = Doorkeeper::AccessToken.create!(
-    application: token.application,
-    resource_owner_id: token.resource_owner_id,
-    scopes: token.scopes,
-    expires_in: 900, # 15 minutes
-    use_refresh_token: false
-  )
-
-  user = User.find(new_token.resource_owner_id)
-
-  render json: {
-    access_token: new_token.token,
-    user: UserBlueprint.render_as_hash(user, view: :auth),
-    expires_in: new_token.expires_in
-  }
-end
-```
-
-### Phase 6: Add TanStack Query
-
-#### 6.1 Install Dependencies
-```bash
-pnpm add @tanstack/svelte-query
-```
-
-#### 6.2 Setup Query Client
-`/src/lib/query/client.ts`:
-```typescript
-import { QueryClient } from '@tanstack/svelte-query'
-
-export const queryClient = new QueryClient({
-  defaultOptions: {
-    queries: {
-      staleTime: 1000 * 60 * 5, // 5 minutes
-      cacheTime: 1000 * 60 * 10, // 10 minutes
-      retry: (failureCount, error: any) => {
-        if (error?.status === 401) return false
-        return failureCount < 3
-      },
-      refetchOnWindowFocus: false
-    },
-    mutations: {
-      retry: false
-    }
-  }
-})
-```
-
-#### 6.3 Use in Components
-```svelte
-<script lang="ts">
-  import { createQuery, createMutation } from '@tanstack/svelte-query'
-  import { partyAdapter } from '$lib/api/adapters'
-
-  const partyQuery = createQuery({
-    queryKey: ['party', shortcode],
-    queryFn: () => partyAdapter.getByShortcode(shortcode),
-    enabled: !!shortcode
-  })
-
-  const updateMutation = createMutation({
-    mutationFn: (data) => partyAdapter.update(shortcode, data),
-    onSuccess: () => {
-      queryClient.invalidateQueries(['party', shortcode])
-    }
-  })
-</script>
-
-{#if $partyQuery.isLoading}
-  <Loading />
-{:else if $partyQuery.error}
-  <Error message={$partyQuery.error.message} />
-{:else if $partyQuery.data}
-  <Party data={$partyQuery.data} />
-{/if}
-```

-## Testing Strategy
-
-### Unit Tests
-```typescript
-// Test auth store refresh logic
-test('refreshes token when expired', async () => {
-  const mockFetch = vi.fn().mockResolvedValue({
-    ok: true,
-    json: async () => ({
-      access_token: 'new_token',
-      expires_in: 900
-    })
-  })
-
-  authStore.setAuth('old_token', user, new Date(Date.now() - 1000))
-  const token = await authStore.getToken()
-
-  expect(mockFetch).toHaveBeenCalledWith(
-    expect.stringContaining('/auth/refresh'),
-    expect.objectContaining({ method: 'POST' })
-  )
-})
-```
-
-### E2E Tests (Playwright)
-```typescript
-test('grid operations work with auth', async ({ page }) => {
-  // Login
-  await page.goto('/login')
-  await page.fill('[name=email]', 'test@example.com')
-  await page.fill('[name=password]', 'password')
-  await page.click('button[type=submit]')
-
-  // Navigate to party
-  await page.goto('/teams/test-party')
-
-  // Test grid operations
-  await page.click('[data-testid=add-weapon]')
-  await expect(page.locator('.weapon-grid')).toContainText('New Weapon')
-})
-```
-
-## Security Checklist
-
-- [ ] **CSP Headers**: Strict Content Security Policy
-- [ ] **Token TTL**: 15-minute access tokens
-- [ ] **Refresh Rotation**: New refresh token on each use
-- [ ] **Revocation**: Proper logout with token revocation
-- [ ] **CORS**: Explicit origins, no wildcards
-- [ ] **HTTPS**: Secure cookies in production
-- [ ] **XSS Protection**: No token in localStorage
-- [ ] **CSRF**: Not needed with Bearer tokens
-
-## Success Metrics
-
-1. **No 401/404 Errors**: All API calls succeed
-2. **SSR Works**: Server-rendered pages have data
-3. **Fast Refresh**: < 100ms token refresh
-4. **No Token Leaks**: Tokens not in localStorage/sessionStorage
-5. **Performance**: 20% reduction in API latency
-
-## Rollback Plan
-
-If issues arise:
-1. **Feature Flag**: Toggle `USE_DIRECT_API` env var
-2. **Restore Proxies**: Git revert removal commit
-3. **Switch Adapters**: Conditional logic in config.ts
-4. **Monitor**: Check error rates in Sentry

-# Direct API Architecture Plan
-
-## Executive Summary
-
-This document outlines a comprehensive plan to migrate from proxy-endpoint-based API calls to direct API calls in the Hensei SvelteKit application. This change will resolve current authentication and routing errors while simplifying the codebase and improving performance.
-
-### Key Problems Being Solved
-1. **404 Errors**: Grid operations failing due to missing/incorrect proxy endpoints
-2. **401 Authentication Errors**: Cookie-based auth not working properly through proxies
-3. **Complexity**: Maintaining duplicate routing logic in both adapters and proxy endpoints
-4. **Performance**: Extra network hop through proxy adds latency
-5. **Inconsistency**: Some operations use SSR, some use proxies, some try direct calls
-
-### Solution
-Implement direct API calls from the browser to the Rails API using Bearer token authentication, which is the standard approach for modern SvelteKit applications.
-
-## Current Architecture Analysis
-
-### What We Have Now
-
-```
-Browser → SvelteKit Proxy (/api/*) → Rails API (localhost:3000/api/v1/*)
-```
-
-#### Current Authentication Flow
-1. User logs in via `/auth/login/+server.ts`
-2. OAuth token received and stored in httpOnly cookies
-3. Proxy endpoints read cookies and forward to Rails
-4. Rails uses Doorkeeper OAuth to authenticate via Bearer token
-
-#### Current Problems
-- **Proxy Endpoints**: 20+ proxy files in `/src/routes/api/`
-- **Adapter Configuration**: Uses `/api` in browser, expecting proxies that don't exist
-- **Grid Operations**: Broken due to missing/incorrect proxy endpoints
-- **URL Mismatches**: Grid adapter uses wrong URL patterns
-- **Parameter Wrapping**: Inconsistent parameter structures
-
-## Proposed Architecture
-
-### Direct API Calls
-
-```
-Browser → Rails API (localhost:3000/api/v1/*)
-```
-
-#### New Authentication Flow
-1. User logs in and receives OAuth token
-2. Store access token in:
-   - Server-side: httpOnly cookie (for SSR)
-   - Client-side: Memory/store (for browser requests)
-3. Include Bearer token in Authorization header for all API calls
-4. Rails authenticates directly via Doorkeeper
-
-#### CORS Configuration
-Rails already has proper CORS configuration:
-```ruby
-origins %w[localhost:5173 127.0.0.1:5173]
-credentials: true
-methods: %i[get post put patch delete options head]
-```
-
-## Implementation Plan
-
-### Phase 1: Update Authentication System
-
-#### 1.1 Create Token Store
-Create `/src/lib/stores/auth.store.ts`:
-```typescript
-import { writable, get } from 'svelte/store'
-
-interface AuthState {
-  accessToken: string | null
-  user: UserInfo | null
-  expiresAt: Date | null
-}
-
-function createAuthStore() {
-  const { subscribe, set, update } = writable<AuthState>({
-    accessToken: null,
-    user: null,
-    expiresAt: null
-  })
-
-  return {
-    subscribe,
-    setAuth: (token: string, user: UserInfo, expiresAt: Date) => {
-      set({ accessToken: token, user, expiresAt })
-    },
-    clearAuth: () => {
-      set({ accessToken: null, user: null, expiresAt: null })
-    },
-    getToken: () => get(authStore).accessToken
-  }
-}
-
-export const authStore = createAuthStore()
-```
-
-#### 1.2 Update Login Handler
-Modify `/src/routes/auth/login/+server.ts`:
-- Continue setting httpOnly cookies for SSR
-- Also return access token in response for client storage
-
-#### 1.3 Update Root Layout
-Modify `/src/routes/+layout.svelte`:
-- Initialize auth store from page data
-- Handle token refresh
-
-### Phase 2: Update Adapter System
-
-#### 2.1 Fix Adapter Configuration
-Update `/src/lib/api/adapters/config.ts`:
-```typescript
-export function getApiBaseUrl(): string {
-  // Always use direct API URL
-  const base = PUBLIC_SIERO_API_URL || 'http://localhost:3000'
-  return `${base}/api/v1`
-}
-```
-
-#### 2.2 Update Base Adapter
-Modify `/src/lib/api/adapters/base.adapter.ts`:
-```typescript
-protected async request<T>(
-  path: string,
-  options: RequestOptions = {}
-): Promise<T> {
-  // Add Bearer token from auth store
-  const token = authStore.getToken()
-
-  const fetchOptions: RequestInit = {
-    ...options,
-    credentials: 'include', // Still include for CORS
-    headers: {
-      'Content-Type': 'application/json',
-      ...(token ? { 'Authorization': `Bearer ${token}` } : {}),
-      ...(options.headers || {})
-    }
-  }
-
-  // ... rest of implementation
-}
-```
-
-### Phase 3: Fix Grid Adapter Issues
-
-#### 3.1 Fix DELETE Methods
-Update `/src/lib/api/adapters/grid.adapter.ts`:
-```typescript
-async deleteWeapon(params: { id: string; partyId: string }): Promise<void> {
-  return this.request<void>(`/grid_weapons/${params.id}`, {
-    method: 'DELETE'
-  })
-}
-// Similar for deleteCharacter and deleteSummon
-```
-
-#### 3.2 Fix Position Update URLs
-```typescript
-async updateWeaponPosition(params: UpdatePositionParams): Promise<GridWeapon> {
-  const { id, position, container } = params
-  return this.request<GridWeapon>(`/grid_weapons/${id}/update_position`, {
-    method: 'POST',
-    body: { position, container }
-  })
-}
-```
-
-#### 3.3 Fix Swap URLs
-```typescript
-async swapWeapons(params: SwapPositionsParams): Promise<{
-  source: GridWeapon
-  target: GridWeapon
-}> {
-  return this.request('/grid_weapons/swap', {
-    method: 'POST',
-    body: params
-  })
-}
-```
-
-### Phase 4: Remove Proxy Endpoints
-
-Delete the entire `/src/routes/api/` directory:
-```bash
-rm -rf /src/routes/api/
-```
-
-### Phase 5: Update Services
-
-#### 5.1 Party Service
-Update to pass auth token if needed for SSR:
-```typescript
-class PartyService {
-  constructor(private fetch?: typeof window.fetch) {}
-
-  async getByShortcode(shortcode: string): Promise<Party> {
-    // On server, use fetch with cookies
-    // On client, adapter will use auth store
-    return partyAdapter.getByShortcode(shortcode)
-  }
-}
-```
-
-### Phase 6: Update Components
-
-#### 6.1 Party Component
-No changes needed - already uses services correctly
-
-#### 6.2 Search Components
-Update to use adapters directly instead of proxy endpoints
-
-## Files to Change
-
-### Core Authentication Files
-1. `/src/lib/stores/auth.store.ts` - **CREATE** - Token storage
-2. `/src/routes/auth/login/+server.ts` - Return token in response
-3. `/src/routes/+layout.svelte` - Initialize auth store
-4. `/src/routes/+layout.server.ts` - Pass token to client
-
-### Adapter System Files
-5. `/src/lib/api/adapters/config.ts` - Remove proxy logic
-6. `/src/lib/api/adapters/base.adapter.ts` - Add Bearer token support
-7. `/src/lib/api/adapters/grid.adapter.ts` - Fix all URL patterns and methods
-8. `/src/lib/api/adapters/party.adapter.ts` - Ensure proper auth
-9. `/src/lib/api/adapters/search.adapter.ts` - Ensure proper auth
-10. `/src/lib/api/adapters/entity.adapter.ts` - Ensure proper auth
-11. `/src/lib/api/adapters/user.adapter.ts` - Ensure proper auth
-
-### Service Files (Minor Updates)
-12. `/src/lib/services/grid.service.ts` - Already correct
-13. `/src/lib/services/party.service.ts` - Already correct
-14. `/src/lib/services/conflict.service.ts` - Already correct
-
-### Component Files (No Changes)
-- `/src/lib/components/party/Party.svelte` - Already uses services
-- All grid components - Already use context correctly
-
-### Files to DELETE
-15. `/src/routes/api/` - **DELETE ENTIRE DIRECTORY**
-
-### SSR Routes (No Changes Needed)
-- `/src/routes/teams/[id]/+page.server.ts` - Keep as-is
-- `/src/routes/teams/explore/+page.server.ts` - Keep as-is
-- All other `+page.server.ts` files - Keep as-is
-
-## Benefits of This Approach
-
-### Performance
-- **Eliminates proxy latency**: Direct calls are faster
-- **Reduces server load**: No proxy processing
-- **Better caching**: Browser can cache API responses directly
-
-### Simplicity
-- **Less code**: Remove 20+ proxy endpoint files
-- **Single source of truth**: Adapters handle all API logic
-- **Standard pattern**: Follows SvelteKit best practices
-
-### Reliability
-- **Fixes authentication**: Bearer tokens work consistently
-- **Fixes routing**: Direct URLs eliminate 404 errors
-- **Better error handling**: Errors come directly from API
-
-### Developer Experience
-- **Easier debugging**: Network tab shows actual API calls
-- **Less complexity**: No proxy layer to understand
-- **Industry standard**: What most SvelteKit apps do
-
-## Trade-offs and Considerations
-
-### Security Considerations
-1. **API URL exposed**: Browser can see Rails API URL (acceptable)
-2. **Token in memory**: XSS vulnerability (mitigated by httpOnly refresh token)
-3. **CORS required**: Must trust frontend origin (already configured)
-
-### Migration Risks
-1. **Breaking change**: All API calls will change
-2. **Testing required**: Need to test all operations
-3. **Token management**: Need to handle expiry/refresh
-
-### Mitigation Strategies
-1. **Incremental rollout**: Can update adapters one at a time
-2. **Feature flags**: Can toggle between old/new approach
-3. **Comprehensive testing**: Test each operation before removing proxies
-
-## Implementation Timeline
-
-### Day 1: Authentication System
-- Create auth store
-- Update login flow
-- Test authentication
-
-### Day 2: Adapter Updates
-- Update adapter configuration
-- Add Bearer token support
-- Fix Grid adapter URLs
-
-### Day 3: Testing & Cleanup
-- Test all grid operations
-- Test search, favorites, etc.
-- Remove proxy endpoints
-
-### Day 4: Final Testing
-- End-to-end testing
-- Performance testing
-- Documentation updates
-
-## Success Criteria
-
-1. **All grid operations work**: Add, update, delete, move, swap
-2. **Authentication works**: Login, logout, refresh
-3. **No 404 errors**: All API calls succeed
-4. **No 401 errors**: Authentication works consistently
-5. **Performance improvement**: Measurable latency reduction
-
-## Conclusion
-
-This migration to direct API calls will:
-1. **Solve immediate problems**: Fix broken grid operations
-2. **Improve architecture**: Align with SvelteKit best practices
-3. **Reduce complexity**: Remove unnecessary proxy layer
-4. **Improve performance**: Eliminate proxy latency
-5. **Enhance maintainability**: Single source of truth for API logic
-
-The approach is standard for modern SvelteKit applications and is what "9 out of 10 Svelte developers" would implement. It leverages the existing CORS configuration in Rails and uses industry-standard Bearer token authentication.
-
-## Next Steps
-
-1. Review and approve this plan
-2. Create auth store implementation
-3. Update adapters incrementally
-4. Test thoroughly
-5. Remove proxy endpoints
-6. Deploy with confidence

-# Drag-Drop API Endpoints PRD
-
-## Overview
-
-This document outlines the API endpoints required to support drag-and-drop functionality for party grid management in the Hensei application. The frontend has implemented drag-drop interactions, but requires backend endpoints to persist position changes and item swaps.
-
-## Problem Statement
-
-### Current State
-- The API currently only supports add/remove operations for grid items
-- Position changes require removing and re-adding items
-- Swapping items requires multiple API calls (remove both, then add both)
-- This approach is error-prone and creates race conditions
-- No atomic operations for complex moves
-
-### User Impact
-- Drag-drop appears to work visually but doesn't persist
-- Risk of data loss if operations partially fail
-- Poor performance with multiple network requests
-- Inconsistent state between UI and database
-
-## Proposed Solution
-
-Implement dedicated API endpoints that match the drag-drop operations:
-1. **Update Position** - Move an item to an empty slot
-2. **Swap Items** - Exchange positions of two items
-3. **Batch Update** - Handle complex multi-item operations atomically
-
-## API Specifications
-
-### 1. Update Position Endpoints
-
-Move a grid item to a new empty position within the same or different container.
-

-```
-PUT /api/v1/parties/:party_id/grid_weapons/:id/position
-```
-
-**Request Body:**
-```json
-{
-  "position": 5,
-  "container": "main" | "extra"
-}
-```
-
-**Response (200 OK):**

-    { "entity": "weapon", "id": "uuid-2", "action": "swapped", "with": "uuid-3" },
-    { "entity": "summon", "id": "uuid-4", "action": "removed" }
-  ]
-}
-```
-
-## Business Rules
-
-### Position Constraints
-
-#### Characters (0-4, 5-6 for extra)
-- **Main slots (0-4):** Must be sequential, no gaps allowed
-- **Extra slots (5-6):** Can have gaps
-- **Auto-compact:** When moving/removing, shift remaining characters to maintain sequence
-
-#### Weapons (-1 mainhand, 0-8 grid, 9+ extra)
-- **Mainhand (-1):** Not draggable, cannot be target
-- **Grid slots (0-8):** Can have gaps
-- **Extra slots (9+):** Can have gaps
-
-#### Summons (-1 main, 0-3 sub, 4-5 subaura, 6 friend)
-- **Main (-1):** Not draggable, cannot be target
-- **Sub slots (0-3):** Can have gaps
-- **Subaura (4-5):** Can have gaps
-- **Friend (6):** Not draggable, cannot be target
-
-### Validation Rules
-
-1. **Type Matching**
-   - Can only swap/move items of the same type
-   - Cannot mix characters, weapons, and summons
-
-2. **Position Validation**
-   - Target position must be valid for the entity type
-   - Cannot move to restricted positions (mainhand, main summon, friend)
-
-3. **Container Rules**
-   - Items can move between containers (main ↔ extra)
-   - Container must be valid for the entity type
-
-4. **Conflict Resolution**
-   - For weapons: Check Ultima/Opus conflicts
-   - For summons: Check duplicate restrictions
-   - Apply same rules as create operations
-
-## Error Handling
-
-### Common Error Responses
-
-#### 400 Bad Request
-```json
-{
-  "error": "Invalid position",
-  "details": {
-    "position": 10,
-    "max_position": 8,
-    "entity": "weapon"
-  }
-}
-```
-
-#### 403 Forbidden
-```json
-{
-  "error": "Cannot modify restricted slot",
-  "details": {
-    "slot": "mainhand",
-    "reason": "Mainhand weapon cannot be moved via drag-drop"
-  }
-}
-```
-
-#### 409 Conflict
-```json
-{
-  "error": "Operation would create invalid state",
-  "details": {
-    "reason": "Cannot have two Ultima weapons in grid",
-    "conflicting_items": ["uuid-1", "uuid-2"]
-  }
-}
-```
-
-#### 422 Unprocessable Entity
-```json
-{
-  "error": "Validation failed",
-  "details": {
-    "source_id": ["not found"],
-    "target_id": ["belongs to different party"]
-  }
-}
-```
-
-### Rollback Strategy
-
-For batch operations:
-1. Validate all operations before executing any
-2. Use database transaction for atomicity
-3. If any operation fails, rollback entire batch
-4. Return detailed error showing which operation failed
-
-## Implementation Notes
-
-### Backend (Rails API)
-
-1. **Controller Actions**
-   - Add `update_position` action to grid controllers
-   - Add `swap` action to grid controllers
-   - Add `grid_update` action to parties controller
-
-2. **Model Methods**
-   - `GridWeapon#update_position(new_position, container = nil)`
-   - `GridCharacter#update_position(new_position, container = nil)`
-   - `GridSummon#update_position(new_position, container = nil)`
-   - `Party#swap_items(source_item, target_item)`
-   - `Party#apply_grid_operations(operations)`
-
-3. **Validations**
-   - Add position range validators
-   - Add container validators
-   - Ensure conflict rules are checked
-
-4. **Authorization**
-   - Require edit permission (user ownership or edit key)
-   - Use existing `authorize_party_edit!` pattern
-
-### Frontend Integration
-
-1. **API Client Updates**
-   ```typescript
-   // Add to apiClient
-   async updateWeaponPosition(partyId, weaponId, position, container)
-   async updateCharacterPosition(partyId, characterId, position, container)
-   async updateSummonPosition(partyId, summonId, position, container)
-   async swapWeapons(partyId, sourceId, targetId)
-   async swapCharacters(partyId, sourceId, targetId)
-   async swapSummons(partyId, sourceId, targetId)
-   async batchGridUpdate(partyId, operations)
-   ```
-
-2. **Drag Handler Updates**
-   ```typescript
-   // In Party.svelte
-   async function handleMove(source, target) {
-     const result = await apiClient.updateWeaponPosition(
-       party.id,
-       source.itemId,
-       target.position,
-       target.container
-     )
-     party = result.party
-   }
-
-   async function handleSwap(source, target) {
-     const result = await apiClient.swapWeapons(
-       party.id,

-   }
-   ```
-
-## Migration Strategy
-
-### Phase 1: Backend Implementation
-1. Implement new endpoints in Rails API
-2. Add comprehensive tests
-3. Deploy to staging
-
-### Phase 2: Frontend Integration
-1. Add new methods to API client
-2. Update drag handlers to use new endpoints
-3. Keep fallback to old method temporarily
-
-### Phase 3: Validation
-1. Test all drag-drop scenarios
-2. Verify data integrity
-3. Monitor for errors
-
-### Phase 4: Cleanup
-1. Remove old implementation
-2. Remove fallback code
-3. Update documentation
-

-   - Validate all IDs belong to specified party
-   - Rate limiting on batch operations
-
-2. **Input Validation**
-   - Sanitize all position values
-   - Validate container strings
-   - Check array bounds
-
-3. **Audit Trail**
-   - Log all position changes
-   - Track user/edit key for each operation
-   - Monitor for suspicious patterns
-
-## Future Enhancements
-
-1. **Undo/Redo Support**
-   - Track operation history
-   - Implement reverse operations
-   - Client-side undo stack
-
-2. **Optimistic Updates**
-   - Apply changes immediately in UI
-   - Rollback on server rejection
-   - Queue operations for offline support
-
-3. **Bulk Operations**
-   - "Auto-arrange" endpoint
-   - "Clear grid" endpoint
-   - "Copy from template" endpoint
-
-4. **WebSocket Support**
-   - Real-time updates for shared parties
-   - Conflict resolution for simultaneous edits
-   - Live collaboration features
-
-## Conclusion
-
-These API endpoints will provide a robust foundation for drag-drop functionality, ensuring data consistency, good performance, and excellent user experience. The atomic nature of these operations will eliminate current issues with partial updates and race conditions.

-# Drag-and-Drop Implementation PRD
-
-## Overview
-Custom drag-and-drop solution for Granblue Fantasy party management grids (CharacterGrid, SummonGrid, WeaponGrid) using Svelte 5 runes. This is a client-side prototype focused on interaction patterns, built with API integration in mind for future persistence.
-
-## Requirements
-
-### CharacterGrid
-- **Layout**: 5 horizontal slots
-- **Behavior**: Sequential filling (no gaps allowed)
-- **Drag Rules**:
-  - All slots are draggable and droppable
-  - Empty slots automatically sort to the end
-  - Dragging to reorder maintains sequential filling
-
-### SummonGrid
-- **Layout**: Main + Friend (vertical) + 2x2 sub-summons
-- **Positions**:
-  - Main: position -1 (non-draggable)
-  - Sub-summons: positions 0-3 (draggable)
-  - Friend: position 6 (non-draggable)
-- **Drag Rules**:
-  - Sub-summons can have gaps
-  - Can swap filled slots
-  - Can move to empty slots
-
-### WeaponGrid
-- **Layout**: Mainhand (vertical) + 3x3 sub-weapons
-- **Positions**:
-  - Mainhand: position -1 (non-draggable)
-  - Sub-weapons: positions 0-8 (draggable)
-- **Drag Rules**:
-  - Sub-weapons can have gaps
-  - Can swap filled slots
-  - Can move to empty slots
-
-### Cross-Container Support
-- Extra characters (separate container)
-- Subaura summons (positions 4-5)
-- Extra weapons (positions 9+)

-```
-
-## Error Recovery Patterns
-
-### Automatic Retry Logic
-```typescript
-class DragOperationError extends Error {
-  constructor(
-    message: string,
-    public operation: DragOperation,
-    public recoverable: boolean = true
-  ) {
-    super(message)
-    this.name = 'DragOperationError'
-  }
-}
-
-async function retryOperation(operation: DragOperation) {
-  console.log(`🔄 Retrying operation ${operation.id} (attempt ${operation.retryCount + 1})`)
-  
-  try {
-    // Future API call
-    // await api.syncDragOperation(operation)
-    operation.status = 'synced'
-  } catch (error) {
-    if (error instanceof DragOperationError && !error.recoverable) {
-      // Unrecoverable error, rollback
-      rollbackOperation(operation)
-    } else {
-      // Schedule another retry
-      operation.retryCount++
-      if (operation.retryCount < 3) {
-        setTimeout(() => retryOperation(operation), Math.pow(2, operation.retryCount) * 1000)
-      }
-    }
-  }
-}
-```
-
-### User Feedback for Sync Status
-```svelte
-<!-- SyncStatusIndicator.svelte -->
-<script lang="ts">
-  interface Props {
-    status: 'idle' | 'syncing' | 'error'
-    pendingCount: number
-  }
-  
-  let { status, pendingCount }: Props = $props()
-</script>
-
-{#if pendingCount > 0}
-  <div class="sync-indicator" class:error={status === 'error'}>
-    {#if status === 'syncing'}
-      <span class="spinner">⟳</span> Saving changes...
-    {:else if status === 'error'}
-      <span class="error-icon">⚠</span> Sync failed - changes pending
-      <button onclick={retry}>Retry</button>
-    {:else}
-      <span class="pending-icon">●</span> {pendingCount} unsaved {pendingCount === 1 ? 'change' : 'changes'}
-    {/if}
-  </div>
-{/if}
-```
-
-## Custom Drag Preview Specifications
-
-### Visual Customization
-```scss
-.drag-preview {
-  position: fixed;
-  pointer-events: none;
-  z-index: 10000;
-  transform: rotate(3deg) scale(1.05);
-  opacity: 0.9;
-  filter: drop-shadow(0 4px 8px rgba(0, 0, 0, 0.3));
-  transition: transform 0.2s ease-out;
-  
-  .drag-preview-content {
-    background: var(--bg-primary);
-    border: 2px solid var(--accent-color);
-    border-radius: 8px;
-    padding: 8px;
-    display: flex;
-    align-items: center;
-    gap: 8px;
-    
-    img {
-      width: 40px;
-      height: 40px;
-      border-radius: 4px;
-    }
-    
-    span {
-      font-weight: 600;
-      color: var(--text-primary);
-      white-space: nowrap;
-    }
-  }
-}
-
-// Touch device specific styles
-@media (hover: none) {
-  .drag-preview {
-    transform: translateY(-50px) scale(1.1); // Offset from finger
-  }
-}
-```
-
-## Touch/Mobile Interaction Patterns
-
-### Long Press Visual Feedback
-```scss
-.draggable-item {
-  position: relative;
-  
-  &.long-press-active::before {
-    content: '';
-    position: absolute;
-    inset: -4px;
-    border: 2px solid var(--accent-color);
-    border-radius: 8px;
-    animation: pulse 0.5s ease-in-out;
-    pointer-events: none;
-  }
-}
-
-@keyframes pulse {
-  0% {
-    opacity: 0;
-    transform: scale(0.95);
-  }
-  50% {
-    opacity: 1;
-    transform: scale(1);
-  }
-  100% {
-    opacity: 0;
-    transform: scale(1.05);
-  }
-}
-```
-
-### Touch Gesture Configurations
-```typescript
-interface TouchConfig {
-  longPressDuration: number      // 500ms default
-  touchThreshold: number         // 10px movement threshold
-  scrollLockThreshold: number    // 5px to lock scrolling
-  hapticFeedback: boolean       // Enable vibration
-  visualFeedback: boolean       // Show press indicator
-}
-
-// Allow customization per grid type
-const characterGridTouchConfig: TouchConfig = {
-  longPressDuration: 400,      // Faster for experienced users
-  touchThreshold: 15,          // More forgiving
-  scrollLockThreshold: 5,
-  hapticFeedback: true,
-  visualFeedback: true
-}
-```
-
-## Validation Rules
-
-### Console Logging Pattern (Enhanced)
-```typescript
-function validateDrop(source: Position, target: Position): boolean {
-  console.group('🎯 Drop Validation')
-  console.log('Source:', source)
-  console.log('Target:', target)
-  console.log('Queue Length:', state.operationQueue.length)
-
-  try {
-    // Check if operation would create invalid state
-    const wouldCreateInvalidState = checkStateValidity(source, target)
-    if (wouldCreateInvalidState) {
-      console.log('❌ Would create invalid state:', wouldCreateInvalidState)
-      return false
-    }
-
-    // Check item type compatibility
-    if (source.type !== target.expectedType) {
-      console.log('❌ Type mismatch:', source.type, 'vs', target.expectedType)
-      return false
-    }
-
-    // Check position restrictions
-    if (target.position === -1 && !target.allowMainhand) {
-      console.log('❌ Cannot drop in mainhand slot')
-      return false
-    }
-
-    // Check container transfer rules
-    if (source.container !== target.container) {
-      const transferAllowed = validateContainerTransfer(source.container, target.container)
-      if (!transferAllowed) {
-        console.log('❌ Container transfer not allowed')
-        return false
-      }
-      console.log('✅ Valid container transfer')
-    }
-
-    console.log('✅ Drop allowed')
-    return true
-  } catch (error) {
-    console.error('❌ Validation error:', error)
-    state.lastError = error as Error
-    return false
-  } finally {
-    console.groupEnd()
-  }
-}
-```
-
-## Testing Scenarios
-
-### Touch Device Testing
-1. Long press to initiate drag
-2. Drag across viewport boundaries
-3. Multi-touch rejection (only one drag at a time)
-4. Scroll prevention during drag
-5. Touch cancel handling (incoming call, notification)
-
-### Error Recovery Testing
-1. Simulate failed API calls
-2. Test retry mechanism with exponential backoff
-3. Verify rollback of optimistic updates
-4. Test max retry limit behavior
-5. Verify error state UI feedback
-
-### Operation Queue Testing
-1. Queue multiple operations rapidly
-2. Verify operations maintain order
-3. Test queue persistence (page refresh simulation)
-4. Test sync status indicators
-5. Verify batch operation handling
-
-### Drag Preview Testing
-1. Custom preview rendering
-2. Preview position relative to cursor/touch
-3. Preview cleanup on drag end
-4. Preview visibility across z-indexes
-5. Performance with complex preview content
-
-## Performance Optimizations
-
-### Touch Performance
-```typescript
-// Debounce touch move events
-let touchMoveFrame: number | null = null
-
-function handleTouchMove(e: TouchEvent) {
-  if (touchMoveFrame) return
-  
-  touchMoveFrame = requestAnimationFrame(() => {
-    updateDragPosition(e.touches[0])
-    touchMoveFrame = null
-  })
-}
-```
-
-### Operation Queue Optimization
-```typescript
-// Batch operations for efficiency
-function batchOperations(operations: DragOperation[]): BatchedOperation {
-  return {
-    id: crypto.randomUUID(),
-    operations: operations,
-    timestamp: Date.now(),
-    type: 'batch'
-  }
-}
-
-// Deduplicate redundant operations
-function deduplicateQueue(queue: DragOperation[]): DragOperation[] {
-  const seen = new Map<string, DragOperation>()
-  
-  for (const op of queue) {
-    const key = `${op.source.itemId}-${op.target.position}`
-    if (!seen.has(key) || op.timestamp > seen.get(key)!.timestamp) {
-      seen.set(key, op)
-    }
-  }
-  
-  return Array.from(seen.values())
-}
-```
-
-## Future API Contract Requirements
-
-### Expected Endpoints
-```typescript
-interface DragDropAPI {
-  // Single operation
-  syncOperation(operation: DragOperation): Promise<{ success: boolean, error?: string }>
-  
-  // Batch operations
-  syncBatch(operations: DragOperation[]): Promise<BatchSyncResult>
-  
-  // Get current state (for reconciliation)
-  getGridState(gridType: string, partyId: string): Promise<GridState>
-  
-  // Validate operation before performing
-  validateOperation(operation: DragOperation): Promise<ValidationResult>
-}
-```
-
-### Optimistic Update Pattern
-```typescript
-async function performOperationWithOptimisticUpdate(operation: DragOperation) {
-  // 1. Apply optimistic update immediately
-  applyLocalUpdate(operation)
-  
-  // 2. Queue for sync
-  state.operationQueue.push(operation)
-  
-  // 3. Attempt sync (non-blocking)
-  syncOperation(operation).catch(error => {
-    // 4. Rollback on failure
-    if (error.code === 'INVALID_STATE') {
-      rollbackOperation(operation)
-      // Fetch fresh state from server
-      refreshGridState()
-    }
-  })
-}
-```
-
-## Success Metrics

-# Infinite Scrolling Implementation with Runed
-
-## Overview
-
-This document outlines the implementation of infinite scrolling for the Hensei application using Runed's utilities instead of TanStack Query. Runed provides Svelte 5-specific reactive utilities that work seamlessly with runes.
-
-## Current State Analysis
-
-### What We Have
-- **Runed v0.31.1** installed and actively used in the project
-- Established resource patterns (`search.resource.svelte.ts`, `party.resource.svelte.ts`)
-- Pagination with "Previous/Next" links on profile and explore pages
-- API support for pagination via `page` parameter
-- SSR with SvelteKit for initial page loads
-
-### What We Need
-- Automatic loading of next page when user scrolls near bottom
-- Seamless data accumulation without page refreshes
-- Loading indicators and error states
-- Memory-efficient data management
-- Accessibility support
-
-## Architecture Design

-### 3. Enhanced Party Resource
-
-Location: Update `/src/lib/api/adapters/resources/party.resource.svelte.ts`
-
-Add infinite scroll support to existing PartyResource:
-
-```typescript
-// Add to existing PartyResource class
-
-// Infinite scroll for explore/gallery
-exploreInfinite = createInfiniteScrollResource<Party>({
-  fetcher: async (page) => {
-    return await this.adapter.list({ page })
-  },
-  debounceMs: 200,
-  threshold: 300
-})
-
-// Infinite scroll for user parties
-userPartiesInfinite = createInfiniteScrollResource<Party>({
-  fetcher: async (page) => {
-    const username = this.currentUsername // store username when loading
-    return await this.adapter.listUserParties({ username, page })
-  },
-  debounceMs: 200,
-  threshold: 300
-})
-```
-
-### 4. Usage in Routes
-
-#### Profile Page (`/src/routes/[username]/+page.svelte`)
-
-```svelte
-<script lang="ts">
-  import type { PageData } from './$types'
-  import { InfiniteScroll } from '$lib/components/InfiniteScroll.svelte'
-  import ExploreGrid from '$lib/components/explore/ExploreGrid.svelte'
-  import { createInfiniteScrollResource } from '$lib/api/adapters/resources'
-  import { userAdapter } from '$lib/api/adapters'
-  import { getAvatarSrc, getAvatarSrcSet } from '$lib/utils/avatar'
-
-  const { data } = $props() as { data: PageData }
-
-  // Create infinite scroll resource
-  const profileResource = createInfiniteScrollResource({
-    fetcher: async (page) => {
-      const tab = data.tab || 'teams'
-      if (tab === 'favorites' && data.isOwner) {
-        return await userAdapter.getFavorites({ page })
-      }
-      return await userAdapter.getProfile(data.user.username, page)
-    },
-    initialData: data.items,
-    debounceMs: 200
-  })
-
-  // Initialize with SSR data
-  $effect(() => {
-    if (data.items && profileResource.items.length === 0) {
-      profileResource.items = data.items
-      profileResource.page = data.page || 1
-      profileResource.totalPages = data.totalPages
-      profileResource.total = data.total
-    }
-  })
-</script>
-
-<section class="profile">
-  <header class="header">
-    <!-- Header content unchanged -->
-  </header>
-
-  <InfiniteScroll resource={profileResource}>
-    <ExploreGrid items={profileResource.items} />
-
-    {#snippet emptySnippet()}

-
-    {#snippet endSnippet()}
-      <p class="end-message">You've reached the end!</p>
-    {/snippet}
-  </InfiniteScroll>
-</section>
-```
-
-#### Explore Page (`/src/routes/teams/explore/+page.svelte`)
-
-```svelte
-<script lang="ts">
-  import type { PageData } from './$types'
-  import { InfiniteScroll } from '$lib/components/InfiniteScroll.svelte'
-  import ExploreGrid from '$lib/components/explore/ExploreGrid.svelte'
-  import { createInfiniteScrollResource } from '$lib/api/adapters/resources'
-  import { partyAdapter } from '$lib/api/adapters'
-
-  const { data } = $props() as { data: PageData }
-
-  // Create infinite scroll resource

-    fetcher: (page) => partyAdapter.list({ page }),
-    initialData: data.items,
-    pageSize: 20,
-    maxItems: 200 // Limit for performance
-  })
-
-  // Initialize with SSR data
-  $effect(() => {
-    if (data.items && exploreResource.items.length === 0) {
-      exploreResource.items = data.items

-
-<section class="explore">
-  <header>
-    <h1>Explore Teams</h1>
-  </header>
-
-  <InfiniteScroll resource={exploreResource} class="explore-grid">
-    <ExploreGrid items={exploreResource.items} />
-  </InfiniteScroll>
-</section>
-```
-
-## Performance Optimizations
-
-### 1. Virtual Scrolling (Optional)
-For extremely large lists (>500 items), consider implementing virtual scrolling:
-- Use a library like `@tanstack/virtual` or build custom with Svelte
-- Only render visible items + buffer
-- Maintain scroll position with placeholder elements
-
-### 2. Memory Management
-- Set `maxItems` limit to prevent unbounded growth
-- Implement "windowing" - keep only N pages in memory
-- Clear old pages when scrolling forward
-
-### 3. Request Optimization
-- Debounce scroll events (built-in with `debounceMs`)
-- Cancel in-flight requests when component unmounts
-- Implement request deduplication
-
-### 4. Caching Strategy
-- Cache fetched pages in adapter layer
-- Implement stale-while-revalidate pattern
-- Clear cache on user actions (create, update, delete)
-
-## Accessibility Features
-
-### 1. Keyboard Navigation
-- Hidden "Load More" button accessible via Tab
-- Focus management when new content loads
-- Skip links to bypass loaded content
-
-### 2. Screen Reader Support
-- Announce when new content is loading
-- Announce when new content has loaded
-- Announce total item count
-- Announce when end is reached
-
-### 3. Reduced Motion
-```css
-@media (prefers-reduced-motion: reduce) {
-  .spinner {
-    animation: none;
-    opacity: 0.8;
-  }
-}
-```
-
-### 4. ARIA Attributes
-- `role="status"` for loading indicators
-- `aria-live="polite"` for announcements
-- `aria-busy="true"` during loading
-- `aria-label` for interactive elements
-
-## Testing Strategy
-
-### 1. Unit Tests
-```typescript
-import { describe, it, expect } from 'vitest'
-import { InfiniteScrollResource } from '$lib/api/adapters/resources/infiniteScroll.resource.svelte'
-
-describe('InfiniteScrollResource', () => {
-  it('loads initial data', async () => {
-    const resource = createInfiniteScrollResource({
-      fetcher: mockFetcher,
-      initialData: mockData
-    })
-
-    expect(resource.items).toEqual(mockData)
-  })
-
-  it('loads more when triggered', async () => {
-    const resource = createInfiniteScrollResource({
-      fetcher: mockFetcher
-    })
-
-    await resource.load()
-    const initialCount = resource.items.length
-
-    await resource.loadMore()
-    expect(resource.items.length).toBeGreaterThan(initialCount)
-  })
-
-  it('stops loading when no more pages', async () => {
-    // Test hasMore property
-  })
-
-  it('handles errors gracefully', async () => {
-    // Test error states
-  })
-})
-```
-
-### 2. Integration Tests
-- Test scroll trigger at various speeds
-- Test with slow network (throttling)
-- Test error recovery
-- Test memory limits
-- Test accessibility features
-
-### 3. E2E Tests
-```typescript
-test('infinite scroll loads more content', async ({ page }) => {
-  await page.goto('/teams/explore')
-
-  // Initial content should be visible
-  await expect(page.locator('.grid-item')).toHaveCount(20)
-
-  // Scroll to bottom
-  await page.evaluate(() => window.scrollTo(0, document.body.scrollHeight))
-
-  // Wait for more content to load
-  await page.waitForSelector('.grid-item:nth-child(21)')
-
-  // Verify more items loaded
-  const itemCount = await page.locator('.grid-item').count()
-  expect(itemCount).toBeGreaterThan(20)
-})
-```
-
-## Migration Path
-
-### Phase 1: Infrastructure
-1. Create InfiniteScrollResource class
-2. Create InfiniteScroll component
-3. Write unit tests
-
-### Phase 2: Implementation
-1. Update explore page (lowest risk)
-2. Update profile pages
-3. Update other paginated lists
-
-### Phase 3: Optimization
-1. Add virtual scrolling if needed
-2. Implement advanced caching
-3. Performance monitoring
-
-### Phase 4: Polish
-1. Refine loading indicators
-2. Enhance error states
-3. Improve accessibility
-4. Add analytics
-
-## Rollback Plan
-
-If infinite scrolling causes issues:
-1. Keep pagination code in place (commented)
-2. Use feature flag to toggle between pagination and infinite scroll
-3. Can revert per-route if needed
-
-```typescript
-const useInfiniteScroll = $state(
-  localStorage.getItem('feature:infinite-scroll') !== 'false'
-)
-
-{#if useInfiniteScroll}
-  <InfiniteScroll>...</InfiniteScroll>
-{:else}
-  <Pagination>...</Pagination>
-{/if}
-```
-
-## Benefits Over TanStack Query
-
-1. **Native Svelte 5**: Built specifically for Svelte runes
-2. **Simpler API**: No provider setup required
-3. **Smaller Bundle**: Runed is lightweight
-4. **Better Integration**: Works seamlessly with SvelteKit
-5. **Type Safety**: Full TypeScript support with runes
-
-## Potential Challenges
-
-1. **SSR Hydration**: Ensure client picks up where server left off
-2. **Back Navigation**: Restore scroll position to correct item
-3. **Memory Leaks**: Proper cleanup of observers and listeners
-4. **Race Conditions**: Handle rapid scrolling/navigation
-5. **Error Recovery**: Graceful handling of network failures

-# Scroll Restoration Implementation for Custom Containers
-
-## Problem Description
-
-In our SvelteKit application, scroll position isn't resetting when navigating between pages. This issue occurs because:
-
-1. The application uses a custom scrolling container (`.main-content`) instead of the default window/body scrolling
-2. SvelteKit's built-in scroll restoration only works with window-level scrolling
-3. When navigating from a scrolled profile page to a team detail page, the detail page appears scrolled down instead of at the top
-
-### User Experience Impact
-- Users scroll down on a profile page
-- Click on a team to view details
-- The team detail page is already scrolled down (unexpected)
-- This breaks the expected navigation behavior where new pages start at the top
-
-## Research Findings
-
-### SvelteKit's Default Behavior
-- SvelteKit automatically handles scroll restoration for window-level scrolling
-- It stores scroll positions in `sessionStorage` for browser back/forward navigation
-- The `afterNavigate` and `beforeNavigate` hooks provide navigation lifecycle control
-- The navigation `type` parameter distinguishes between different navigation methods
-
-### Limitations with Custom Scroll Containers
-- SvelteKit's scroll handling doesn't automatically work with custom containers (GitHub issues [#937](https://github.com/sveltejs/kit/issues/937), [#2733](https://github.com/sveltejs/kit/issues/2733))
-- The framework only tracks `window.scrollY`, not element-specific scroll positions
-- Using `disableScrollHandling()` is discouraged as it "breaks user expectations" (official docs)
-
-### Community Solutions
-1. Manual scroll management using navigation hooks
-2. Combining `beforeNavigate` for saving positions with `afterNavigate` for restoration
-3. Using the snapshot API for session persistence
-4. Leveraging `requestAnimationFrame` to ensure DOM readiness
-
-## Solution Architecture
-
-### Core Components
-
-1. **Scroll Position Storage**: A Map that stores scroll positions keyed by URL
-2. **Navigation Hooks**: Using `beforeNavigate` and `afterNavigate` for lifecycle management
-3. **Navigation Type Detection**: Using the `type` parameter to distinguish navigation methods
-4. **DOM Reference**: Direct reference to the `.main-content` scrolling container
-
-### Navigation Type Disambiguation
-
-The solution uses SvelteKit's navigation `type` to determine the appropriate scroll behavior:
-
-| Navigation Type | Value | Behavior | Example |
-|----------------|-------|----------|---------|
-| Initial Load | `'enter'` | Scroll to top | First visit to the app |
-| Link Click | `'link'` | Scroll to top | Clicking `<a>` tags |
-| Programmatic | `'goto'` | Scroll to top | Using `goto()` function |
-| Browser Navigation | `'popstate'` | Restore position | Back/forward buttons |
-| Leave App | `'leave'` | N/A | Navigating away |
-
-## Implementation
-
-### Complete Solution Code
-
-Add the following to `/src/routes/+layout.svelte`:
-
-```svelte
-<script lang="ts">
-  import { afterNavigate, beforeNavigate } from '$app/navigation'
-  import { browser } from '$app/environment'
-  // ... other imports
-
-  // Reference to the scrolling container
-  let mainContent: HTMLElement | undefined;
-
-  // Store scroll positions for each visited route
-  const scrollPositions = new Map<string, number>();
-
-  // Save scroll position before navigating away
-  beforeNavigate(({ from }) => {
-    if (from && mainContent) {
-      // Create a unique key including pathname and query params
-      const key = from.url.pathname + from.url.search;
-      scrollPositions.set(key, mainContent.scrollTop);
-    }
-  });
-
-  // Handle scroll restoration or reset after navigation
-  afterNavigate(({ from, to, type }) => {
-    if (!mainContent) return;
-
-    // Use requestAnimationFrame to ensure DOM has updated
-    requestAnimationFrame(() => {
-      const key = to.url.pathname + to.url.search;
-
-      // Only restore scroll for browser back/forward navigation
-      if (type === 'popstate' && scrollPositions.has(key)) {
-        // User clicked back/forward button - restore their position
-        mainContent.scrollTop = scrollPositions.get(key) || 0;
-      } else {
-        // Any other navigation type (link, goto, enter, etc.) - go to top
-        mainContent.scrollTop = 0;
-      }
-    });
-  });
-
-  // Optional: Export snapshot for session persistence
-  export const snapshot = {
-    capture: () => {
-      if (!mainContent) return { scroll: 0, positions: [] };
-      return {
-        scroll: mainContent.scrollTop,
-        positions: Array.from(scrollPositions.entries())
-      };
-    },
-    restore: (data) => {
-      if (!data || !mainContent) return;
-      // Restore saved positions map
-      if (data.positions) {
-        scrollPositions.clear();
-        data.positions.forEach(([key, value]) => {
-          scrollPositions.set(key, value);
-        });
-      }
-      // Restore current scroll position after DOM is ready
-      if (browser) {
-        requestAnimationFrame(() => {
-          if (mainContent) mainContent.scrollTop = data.scroll;
-        });
-      }
-    }
-  };
-</script>
-
-<!-- Update the main content element to include the reference -->
-<main class="main-content" bind:this={mainContent}>
-  {@render children?.()}
-</main>
-```
-
-### Integration Steps
-
-1. **Import Navigation Hooks**
-   ```typescript
-   import { afterNavigate, beforeNavigate } from '$app/navigation'
-   ```
-
-2. **Add Container Reference**
-   Change the `<main>` element to include `bind:this={mainContent}`
-
-3. **Initialize Scroll Position Map**
-   Create a Map to store positions: `const scrollPositions = new Map<string, number>()`
-
-4. **Implement Navigation Handlers**
-   Add the `beforeNavigate` and `afterNavigate` callbacks as shown above
-
-5. **Optional: Add Snapshot Support**
-   Export the snapshot object for session persistence across refreshes
-
-## Navigation Scenarios
-
-### 1. Back/Forward Button Navigation
-- **Detection**: `type === 'popstate'`
-- **Action**: Restore saved scroll position if it exists
-- **Example**: User views profile → scrolls down → clicks team → clicks back button → returns to scrolled position
-
-### 2. Link Click Navigation
-- **Detection**: `type === 'link'`
-- **Action**: Reset scroll to top
-- **Example**: User clicks on any `<a>` tag or navigation link → new page starts at top
-
-### 3. Page Refresh
-- **Detection**: Map is empty after refresh (unless snapshot is used)
-- **Action**: Start at top (default behavior)
-- **Example**: User refreshes browser → page loads at top
-
-### 4. Programmatic Navigation
-- **Detection**: `type === 'goto'`
-- **Action**: Reset scroll to top
-- **Example**: Code calls `goto('/teams')` → page starts at top
-
-### 5. Direct URL Access
-- **Detection**: `type === 'enter'`
-- **Action**: Start at top
-- **Example**: User enters URL directly or opens bookmark → page starts at top
-
-## Edge Cases
-
-### Scenario: Refresh Then Back
-- User refreshes page (Map is cleared)
-- User navigates back
-- Result: Scrolls to top (no stored position)
-
-### Scenario: Same URL Different Navigation
-- Via link click: Always scrolls to top
-- Via back button: Restores position if available
-
-### Scenario: Query Parameters
-- Positions are stored with full path + query
-- `/teams?page=2` and `/teams?page=3` have separate positions
-
-### Scenario: Memory Management
-- Positions accumulate during session
-- Cleared on page refresh (unless using snapshot)
-- Consider implementing a size limit for long sessions
-
-## Best Practices
-
-### 1. Avoid `disableScrollHandling`
-The official documentation states this is "generally discouraged, since it breaks user expectations." Our solution works alongside SvelteKit's default behavior.
-
-### 2. Use `requestAnimationFrame`
-Ensures the DOM has fully updated before manipulating scroll position:
-```javascript
-requestAnimationFrame(() => {
-  mainContent.scrollTop = position;
-});
-```
-
-### 3. Include Query Parameters in Keys
-Important for paginated views where each page should maintain its own scroll position:
-```javascript
-const key = url.pathname + url.search;
-```
-
-### 4. Progressive Enhancement
-The solution gracefully degrades if JavaScript is disabled, falling back to default browser behavior.
-
-### 5. Type Safety
-Use TypeScript types for better maintainability:
-```typescript
-let mainContent: HTMLElement | undefined;
-const scrollPositions = new Map<string, number>();
-```
-

-# Search Sidebar Refactor Plan (Infinite Scroll + Legacy Parity)
-
-This plan upgrades `src/lib/components/panels/SearchSidebar.svelte` to support infinite-scrolling search with cancellable requests, modular components, and accessible UX. It also aligns result content with our previous app’s components so we show the most useful fields.
-
-Relevant packages to install:
-https://runed.dev/docs/getting-started
-https://runed.dev/docs/utilities/resource
-
-## Goals
-- Smooth, infinite-scrolling search with debounced input and request cancellation.
-- Modular, testable components (header, filters, list, items).
-- Strong accessibility and keyboard navigation.
-- Reuse legacy field choices for results (image, name, uncap, tags).
-
-## Legacy Result Fields (from hensei-web)
-Reference: `../hensei-web/components/*Result`
-- Common
-  - Thumbnail (grid variant), localized name.
-  - `UncapIndicator` with FLB/ULB/Transcendence (stage displayed as 5 in old UI).
-  - Element tag.
-- Weapons
-  - Proficiency tag.
-- Summons
-  - “Subaura” badge (if applicable/available from API).
-- Characters
-  - Respect `special` flag for `UncapIndicator`.
-- Implementation
-  - Use our image helper (`get*Image`) and placeholders; do not hardcode paths.
-
-## Data Flow
-- Unified adapter: `searchResource(type, params, { signal })` wraps current resource-specific search functions and normalizes the output to `{ results, total, nextCursor? }`.
-- Debounce input: 250–300ms.
-- Cancellation: AbortController cancels prior request when query/filters/cursor change.
-- Single orchestrating effect: listens to `open`, `type`, `debouncedQuery`, and `filters`. Resets state and triggers initial fetch.
-
-## Infinite Scrolling
-- IntersectionObserver sentinel at list bottom triggers `loadMore()` when visible.
-- Guards: `isLoading`, `hasMore`, `error` prevent runaway loads.
-- Use Runed's `resource()` for fetching (Svelte 5‑native) instead of TanStack Query:
-  - Reactive key: `{ type, query: debouncedQuery, filters, page }`.
-  - Resource fn receives `AbortSignal` for cancellation.
-  - `keepPreviousValue: true` to avoid flicker on refresh.
-  - Append or replace items based on `page`.
-
-### Runed setup
-- Install: `pnpm add runed`
-- Import where needed: `import { resource } from 'runed'`
-- No extra config required; works seamlessly with Svelte 5 runes ($state/$derived/$effect).
-
-## State Orchestration
-- State: `items[]`, `isLoading`, `error`, `hasMore`, `page`, `debouncedQuery`, `filters`, `open`.
-- Reset state on open/type/query/filters change; cancel in-flight; fetch page 1.
-- Persist last-used filters per type in localStorage and restore on open.
-- Optional lightweight cache: `Map<string, { items, page, hasMore, timestamp }>` keyed by `{ type, query, filters }` with small TTL.
-
-## UX & Accessibility
-- Loading skeletons for image/title/badges.
-- Error state with Retry and helpful copy.
-- Empty state: “No results — try widening filters.”
-- Keyboard
-  - Focus trap when open; restore focus to trigger on close.
-  - Arrow Up/Down to move highlight; Enter to select; Escape to close.
-  - `aria-live=polite` announcements for loading and result counts.
-- Performance
-  - Pre-fetch next page when 60–70% scrolled (if not using IO sentinel aggressively).
-  - Virtualization as a stretch goal if lists become large.
-
-## Componentization
-- `SearchSidebarHeader.svelte`: search input (debounced), close button, result count.
-- `FilterGroup.svelte`: Element, Rarity, Proficiency; emits `{ element?: number[], rarity?: number[], proficiency1?: number[] }`.
-- Result items (choose either specialized components or generic + slots)
-  - `WeaponResultItem.svelte`: image, name, UncapIndicator, [Element, Proficiency].
-  - `SummonResultItem.svelte`: image, name, UncapIndicator, [Element, Subaura?].
-  - `CharacterResultItem.svelte`: image, name, UncapIndicator(special), [Element].
-- `ResultList.svelte`: renders items, manages sentinel and keyboard focus.
-- `searchResource.ts`: adapter normalizing current API responses.
-
-## Normalized API Contract
-- Input
-  - `type: 'weapon' | 'character' | 'summon'`
-  - `query?: string`
-  - `filters: { element?: number[]; rarity?: number[]; proficiency1?: number[] }`
-  - `cursor?: { page?: number; perPage?: number }` (or token-ready for future)
-  - `signal: AbortSignal`
-- Output
-  - `{ results: any[]; total: number; nextCursor?: { page?: number } }`
-
-## Tasks (Phased)
-
-### Phase 1 — Infra & UX Baseline
-- [ ] Add `searchResource` adapter + types; normalize outputs.
-- [ ] Debounce input and wire AbortController for cancellation.
-- [ ] Consolidate effects; initialize/reset state predictably.
-- [ ] Implement infinite scroll via IntersectionObserver; add guards.
-- [ ] Add skeleton, error, and empty states (minimal styles).
-
-### Phase 2 — Componentization & Fields
-- [ ] Build `FilterGroup` (Element, Rarity, Proficiency) and emit filters.
-- [ ] Implement `WeaponResultItem`, `SummonResultItem`, `CharacterResultItem` with fields per legacy.
-- [ ] Extract `SearchSidebarHeader` (input, count, close) and `ResultList` (items + sentinel).
-
-### Phase 3 — A11y & Keyboard
-- [ ] Add focus trap and restore focus on close.
-- [ ] Apply listbox/option roles; `aria-live` for loading/count.
-- [ ] Arrow/Enter/Escape handlers; scroll highlighted item into view.
-
-### Phase 4 — Persistence & Performance
-- [ ] Persist filters per type in localStorage; hydrate on open.
-- [ ] Optional: add small in-memory cache keyed by `{ type, query, filters }` (TTL 2–5 min).
-- [ ] Optional: prefetch next page on near-end scroll.
-- [ ] Optional: list virtualization if needed.
-
-## Example: resource() Outline (Runed)
-```
-// Debounce query (250–300ms)
-let query = $state('')
-let debouncedQuery = $state('')
-let debounceTimer: any
-$effect(() => {
-  clearTimeout(debounceTimer)
-  debounceTimer = setTimeout(() => (debouncedQuery = query.trim()), 280)
-})
-
-// Paging + items
-let page = $state(1)
-let items: any[] = $state([])
-let hasMore = $state(true)
-
-const params = $derived(() => ({ type, query: debouncedQuery, filters, page }))
-
-import { resource } from 'runed'
-const searchRes = resource(
-  params,
-  async (p, ctx) => searchResource(p.type, { query: p.query, filters: p.filters, page: p.page, perPage: 20 }, { signal: ctx.signal }),
-  { keepPreviousValue: true }
-)
-
-$effect(() => {
-  const val = searchRes.value
-  if (!val) return
-  if (page === 1) items = val.results
-  else items = [...items, ...val.results]
-  hasMore = val.nextCursor?.page ? true : false // or derive from total_pages
-})
-
-// IntersectionObserver sentinel triggers loadMore
-function onIntersect() {
-  if (!searchRes.loading && hasMore) page += 1
-}
-```
-
-### Phase 5 — Tests & Polish
-- [ ] Unit tests for adapter (debounce + abort cases).
-- [ ] Interaction tests (keyboard nav, infinite scroll, retry/reload).
-- [ ] Visual QA: confirm result item content matches legacy intent.
-
-## Acceptance Criteria
-- Infinite scrolling with smooth loading; no duplicate/stale requests.
-- Results show image, name, uncap, and tags mirroring legacy components.
-- Accessible: screen-reader friendly, keyboard navigable, focus managed.
-- Filters and results are modular and easily testable.
-- Caching (or local persistence) makes repeat searches feel instant.
-
-## Notes / Risks
-- svelte-query adds a dependency; keep adapter thin to allow opting in later.
-- Subaura badge requires API support; if not present, hide or infer conservatively.
-- Virtualization is optional; only implement if list length causes perf issues.
-
-## Extending To Teams Explore
-
-The same resource-based, infinite-scroll pattern should power `src/routes/teams/explore/+page.svelte` to keep UX and tech consistent.
-
-Guidelines:
-- Shared primitives
-  - Reuse the resource() orchestration, IntersectionObserver sentinel, and list state (`items`, `page`, `hasMore`, `isLoading`, `error`).
-  - Reuse skeleton, empty, and error components/styles for visual consistency.
-  - Optional: extract a tiny `use:intersect` action and a generic `InfiniteList.svelte` wrapper.
-- Explore adapter
-  - Create `exploreResource(params, { signal })` that normalizes `{ results, total, nextCursor }` from the teams listing endpoint.
-  - Inputs: `query?`, `filters?` (element, tags), `sort?` (newest/popular), `page`, `perPage`.
-- SSR-friendly
-  - `+page.server.ts` fetches `page=1` for SEO and first paint; client continues with infinite scroll.
-  - Initialize client state from server data; enable `keepPreviousValue` to avoid flicker on hydration.
-- URL sync
-  - Reflect `query`, `filters`, `sort`, and `page` in search params. On mount, hydrate state from the URL.
-  - Improves shareability and back/forward navigation.
-- Cards and filters
-  - Implement `TeamCard.svelte` (thumbnail, name/title, owner, likes, updatedAt, element/tags) with a matching skeleton card.
-  - Build `TeamsFilterGroup.svelte` mirroring the sidebar’s `FilterGroup.svelte` experience.
-- Performance
-  - Lazy-load images with `loading="lazy"` and `decoding="async"`; consider prefetching page+1 on near-end scroll.
-  - Virtualization only if card density leads to perf issues.
-
-By following these conventions, the search sidebar and explore page share the same mental model, enabling rapid iteration and less bespoke code per page.

-# Transcendence Star Popover Fix - Implementation Plan
-
-## Problem Statement
-
-The TranscendenceStar component's popover interface has three critical issues:
-
-1. **Z-index layering issue**: The popover (z-index: 100) appears below weapon images and other UI elements
-2. **Overflow clipping**: The parent container `.page-wrap` has `overflow-x: auto` which clips the popover
-3. **Viewport positioning**: The popover can appear partially off-screen when the star is near the bottom of the viewport
-
-## Current Implementation Analysis
-
-### File Structure
-- Component: `/src/lib/components/uncap/TranscendenceStar.svelte`
-- Fragment: `/src/lib/components/uncap/TranscendenceFragment.svelte`
-
-### Current Approach
-- Popover is rendered as a child div with `position: absolute`
-- Uses local state `isPopoverOpen` to control visibility
-- Z-index set to 100 (below tooltips at 1000)
-- No viewport edge detection or smart positioning
-
-## Solution Architecture
-
-### 1. Portal-Based Rendering
-Use bits-ui Portal component to render the popover outside the DOM hierarchy, avoiding overflow clipping.
-
-**Benefits:**
-- Escapes any parent overflow constraints
-- Maintains React-like portal behavior
-- Already proven pattern in Dialog.svelte
-
-### 2. Z-index Hierarchy Management
-
-Current z-index levels in codebase:
-- Tooltips: 1000
-- Navigation/Side panels: 50
-- Fragments: 32
-- Current popover: 100
-
-**Solution:** Set popover z-index to 1001 (above tooltips)
-
-### 3. Smart Positioning System
-
-#### Position Calculation Algorithm
-
-```typescript
-interface PopoverPosition {
-  top: number;
-  left: number;
-  placement: 'above' | 'below';
-}
-
-function calculatePopoverPosition(
-  starElement: HTMLElement,
-  popoverWidth: number = 80,
-  popoverHeight: number = 100
-): PopoverPosition {
-  const rect = starElement.getBoundingClientRect();
-  const viewport = {
-    width: window.innerWidth,
-    height: window.innerHeight
-  };
-
-  // Calculate available space
-  const spaceBelow = viewport.height - rect.bottom;
-  const spaceAbove = rect.top;
-  const spaceRight = viewport.width - rect.right;
-  const spaceLeft = rect.left;
-
-  // Determine vertical placement
-  const placement = spaceBelow < popoverHeight && spaceAbove > spaceBelow
-    ? 'above'
-    : 'below';
-
-  // Calculate position
-  let top = placement === 'below'
-    ? rect.bottom + 8  // 8px gap
-    : rect.top - popoverHeight - 8;
-
-  // Center horizontally on star
-  let left = rect.left + (rect.width / 2) - (popoverWidth / 2);
-
-  // Adjust horizontal position if too close to edges
-  if (left < 8) {
-    left = 8; // 8px from left edge
-  } else if (left + popoverWidth > viewport.width - 8) {
-    left = viewport.width - popoverWidth - 8; // 8px from right edge
-  }
-
-  return { top, left, placement };
-}
-```
-
-### 4. Implementation Details
-
-#### State Management
-```typescript
-// New state variables
-let popoverPosition = $state<PopoverPosition | null>(null);
-let popoverElement: HTMLDivElement;
-```
-
-#### Position Update Effect
-```typescript
-$effect(() => {
-  if (isPopoverOpen && starElement) {
-    const updatePosition = () => {
-      popoverPosition = calculatePopoverPosition(starElement);
-    };
-
-    // Initial position
-    updatePosition();
-
-    // Update on scroll/resize
-    window.addEventListener('scroll', updatePosition, true);
-    window.addEventListener('resize', updatePosition);
-
-    return () => {
-      window.removeEventListener('scroll', updatePosition, true);
-      window.removeEventListener('resize', updatePosition);
-    };
-  }
-});
-```
-
-#### Template Structure
-```svelte
-{#if interactive && isPopoverOpen && popoverPosition}
-  <Portal>
-    <div
-      class="popover"
-      class:above={popoverPosition.placement === 'above'}
-      style="top: {popoverPosition.top}px; left: {popoverPosition.left}px"
-      bind:this={popoverElement}
-    >
-      <div class="fragments">
-        <!-- existing fragment content -->
-      </div>
-      <div class="level">
-        <!-- existing level display -->
-      </div>
-    </div>
-  </Portal>
-{/if}
-```
-
-#### Style Updates
-```scss
-.popover {
-  position: fixed;
-  z-index: 1001;
-
-  // Remove static positioning
-  // top: -10px; (remove)
-  // left: -10px; (remove)
-
-  // Add placement variants
-  &.above {
-    // Arrow or visual indicator for above placement
-  }
-
-  // Smooth appearance
-  animation: popover-appear 0.2s ease-out;
-}
-
-@keyframes popover-appear {
-  from {
-    opacity: 0;
-    transform: translateY(-4px);
-  }
-  to {
-    opacity: 1;
-    transform: translateY(0);
-  }
-}
-```
-
-## Implementation Steps
-
-1. **Install/verify bits-ui Portal availability**
-   - Check if Portal is exported from bits-ui
-   - If not available, create custom portal implementation
-
-2. **Add positioning logic**
-   - Create calculatePopoverPosition function
-   - Add position state management
-   - Add scroll/resize listeners
-
-3. **Update template**
-   - Wrap popover in Portal component
-   - Apply dynamic positioning styles
-   - Add placement classes
-
-4. **Update styles**
-   - Change to position: fixed
-   - Increase z-index to 1001
-   - Add animation for smooth appearance
-   - Handle above/below placement variants
-
-5. **Testing**
-   - Test near all viewport edges
-   - Test with scrolling
-   - Test with window resize
-   - Verify z-index layering
-   - Confirm no overflow clipping
-
-## Alternative Approaches Considered
-
-### Floating UI Library
-- Pros: Robust positioning, automatic flipping, virtual element support
-- Cons: Additional dependency, may be overkill for simple use case
-- Decision: Start with custom implementation, can migrate if needed
-
-### Tooltip Component Reuse
-- Pros: Consistent behavior with existing tooltips
-- Cons: Tooltips likely simpler, may not support interactive content
-- Decision: Custom implementation for specific transcendence needs
-
-## Success Criteria
-
-- [ ] Popover appears above all other UI elements
-- [ ] No clipping by parent containers
-- [ ] Smart positioning avoids viewport edges
-- [ ] Smooth transitions and animations
-- [ ] Click outside properly closes popover
-- [ ] Position updates on scroll/resize
-- [ ] Works on all screen sizes

-# Type Migration Strategy: Existing Types vs New Architecture
-
-## Current State Analysis
-
-After examining the 35+ type definition files in `/src/lib/types/`, here's how they'll interact with the new architecture:
-
-## Types to REPLACE
-
-These types have direct conflicts with the new architecture and will be replaced:
-
-### 1. Core Entity Types (Will be replaced with clean versions)
-- **Party.d.ts** → New `Party` interface
-  - Current uses snake_case (e.g., `full_auto`, `charge_attack`)
-  - New version will use camelCase consistently
-  - Will properly type grid items with named entities
-
-- **GridWeapon.d.ts** → New `GridWeapon` interface
-  - Current has `object: Weapon` (matching API's naming)
-  - New version will have `weapon: Weapon` (semantic naming)
-
-- **GridCharacter.d.ts** → New `GridCharacter` interface
-  - Current has `object: Character`
-  - New version will have `character: Character`
-
-- **GridSummon.d.ts** → New `GridSummon` interface
-  - Current has `object: Summon`
-  - New version will have `summon: Summon`
-
-### 2. Redundant View Types (Will be removed entirely)
-- **From party.ts schema file:**
-  - `PartyView` → Use new `Party` only
-  - `GridWeaponItemView` → Use new `GridWeapon` only
-  - `GridCharacterItemView` → Use new `GridCharacter` only
-  - `GridSummonItemView` → Use new `GridSummon` only
-
-## Types to KEEP
-
-These types serve specific purposes and will remain:
-
-### 1. UI State Types
-- **CheckedState.d.ts** - UI selection state
-- **ElementState.d.ts** - Element filtering state
-- **ProficiencyState.d.ts** - Proficiency filtering state
-- **RarityState.d.ts** - Rarity filtering state
-- **FilterSet.d.ts** - Filter combinations
-
-### 2. Domain-Specific Types
-- **Awakening.d.ts** - Enhancement system
-- **WeaponKey.d.ts** - Weapon upgrades
-- **SimpleAxSkill.d.ts** - AX skill system
-- **ItemSkill.d.ts** - Item skills
-- **TeamElement.d.ts** - Team element logic
-
-### 3. Infrastructure Types
-- **User.d.ts** - User authentication
-- **AccountCookie.d.ts** - Auth cookies
-- **UserCookie.d.ts** - User preferences
-- **GranblueCookie.d.ts** - Game data cookies
-- **AppUpdate.d.ts** - App versioning
-
-### 4. Helper Types
-- **OnClickEvent.d.ts** - Event handlers
-- **MentionItem.d.ts** - Rich text mentions
-- **declarations.d.ts** - Module declarations
-- **index.d.ts** - Type exports and utilities
-
-## Types to MODIFY
-
-These need minor updates to work with new architecture:
-
-### 1. Base Entity Types
-- **Weapon.d.ts** - Keep structure, but ensure camelCase
-- **Character.d.ts** - Keep structure, but ensure camelCase
-- **Summon.d.ts** - Keep structure, but ensure camelCase
-- **Job.d.ts** - Keep structure, but ensure camelCase
-- **JobSkill.d.ts** - Keep structure, but ensure camelCase
-- **JobAccessory.d.ts** - Keep structure, but ensure camelCase
-- **Raid.d.ts** - Keep structure, but ensure camelCase
-- **RaidGroup.d.ts** - Keep structure, but ensure camelCase
-- **Guidebook.d.ts** - Keep structure, but ensure camelCase
-
-## Migration Plan
-
-### Phase 1: Create New Type Definitions
-1. Create `/src/lib/types/api/` directory for new clean types
-2. Define base entities matching Rails blueprints
-3. Use consistent camelCase throughout
-4. Properly name nested entities (`weapon`, not `object`)
-
-### Phase 2: Update API Client
-1. Implement automatic transformation layer in `/src/lib/api/client.ts`
-2. Handle `object` → proper entity name mapping
-3. Apply snake_case ↔ camelCase transformation
-
-### Phase 3: Gradual Component Migration
-1. Update components to import from new type locations
-2. Change property access from `item.object` to `item.weapon/character/summon`
-3. Remove type casts and `as any` usage
-
-### Phase 4: Cleanup
-1. Delete old conflicting type files
-2. Remove PartyView and other view types from schemas
-3. Update all imports
-
-## Type Import Strategy
-
-```typescript
-// OLD (current)
-import type { Party } from '$lib/types/Party'
-import type { GridWeapon } from '$lib/types/GridWeapon'
-import type { PartyView } from '$lib/api/schemas/party'
-
-// NEW (after migration)
-import type { Party, GridWeapon, GridCharacter, GridSummon } from '$lib/types/api/party'
-import type { Weapon, Character, Summon } from '$lib/types/api/entities'
-// No more PartyView - just use Party
-```
-
-## Benefits of This Approach
-
-1. **Preserves existing work**: Keeps all UI state types, domain logic types
-2. **Single source of truth**: One `Party` type, not Party + PartyView
-3. **Type safety**: Proper TypeScript types throughout
-4. **Clean naming**: `weapon` instead of `object` everywhere
-5. **Backwards compatible**: Can migrate gradually, component by component
-
-## Example Type Transformation
-
-### Before (Current)
-```typescript
-// Multiple conflicting types
-interface Party { // from Party.d.ts
-  full_auto: boolean
-  weapons: Array<GridWeapon>
-}
-
-interface GridWeapon { // from GridWeapon.d.ts
-  object: Weapon  // Confusing naming
-}
-
-interface PartyView { // from party.ts schema
-  fullAuto?: boolean
-  weapons: GridWeaponItemView[]
-}
-```
-
-### After (New Architecture)
-```typescript
-// Single clean type
-interface Party {
-  fullAuto: boolean
-  weapons: GridWeapon[]
-}
-
-interface GridWeapon {
-  weapon: Weapon  // Semantic naming
-  position: number
-  mainhand?: boolean
-  // ... other fields
-}
-// No PartyView needed!
-```
-
-## Implementation Order
-
-1. **Start with Party types** - Most critical for hydration fix
-2. **Then Grid types** - Fix the object → entity naming
-3. **Keep all other types** - They're working fine
-4. **Update components** - As needed for functionality
-
-This approach minimizes disruption while fixing the core hydration and type safety issues.
