 ### Build Process

 ```bash
-pnpm build      # Creates standalone Next.js build in .next/standalone/
+pnpm build      # Next.js standalone build + asset copying
 ```

-The build creates a standalone application that includes all dependencies for deployment.
+The build process:
+1. Creates standalone Next.js build in `.next/standalone/`
+2. Copies `public/` assets to standalone directory
+3. Copies static assets (`.next/static`) to standalone directory
+4. Results in a fully self-contained application

 ## API Architecture

-### Endpoints
+### Hono.js Integration
+
+The backend uses Hono.js mounted via Next.js API routes with a catch-all route at `/api/[[...route]]/route.ts`. This provides:
+
+- **Type-safe API**: Full TypeScript inference from server to client
+- **Zod validation**: Request/response validation throughout the stack
+- **Performance**: Lightweight runtime with minimal overhead
+- **Streaming**: Native SSE support for real-time features
+
+### API Endpoints

 - `GET /api/projects` - List all projects with metadata
 - `GET /api/projects/:projectId` - Get project details and sessions
 - `GET /api/projects/:projectId/sessions/:sessionId` - Get conversation data
 - `GET /api/events/state_changes` - Server-Sent Events for real-time updates

-### Data Flow
+### Data Flow Architecture

-1. **File System → Parser**: Read JSONL files from `~/.claude/projects/`
-2. **Parser → Validation**: Validate each line against Zod conversation schemas
-3. **API → Frontend**: Type-safe data transfer with TanStack Query
-4. **Real-time**: File watcher emits SSE events for live updates

+projects/      +schemas    +streaming   /route.ts      +hooks        +components
+```
+
+1. **File System Reading**: Services read JSONL files from `~/.claude/projects/`
+2. **Schema Validation**: Each line validated against modular Zod conversation schemas
+3. **API Layer**: Hono.js routes provide type-safe endpoints with streaming support
+4. **Client Integration**: TanStack Query manages server state with error boundaries
+5. **Real-time Updates**: File watcher emits SSE events, automatically updating UI

 ### Backend Services

-#### Core Services (`src/server/service/`)
+#### Project Services (`src/server/service/project/`)

 - **`getProjects()`** - Scans project directories, returns sorted metadata
 - **`getProject(projectId)`** - Fetches project details and session list
- **`getSession(projectId, sessionId)`** - Parses JSONL conversation files
- **`parseJsonl()`** - Validates JSONL lines against conversation schema
+- **`getProjectMeta(projectId)`** - Fast metadata extraction

-#### File Watching (`src/server/service/file-watcher.ts`)
+#### Session Services (`src/server/service/session/`)

- Singleton service using Node.js `fs.watch()` 
- Monitors `~/.claude/projects/` recursively
- Emits `project_changed` and `session_changed` events
- Includes heartbeat mechanism (30s intervals)
+- **`getSessions(projectId)`** - List sessions for a project
+- **`getSession(projectId, sessionId)`** - Parse JSONL conversation files
+- **`getSessionMeta(projectId, sessionId)`** - Extract session metadata
+
+#### Event System (`src/server/service/events/`)
+
+- **`fileWatcher.ts`** - FileWatcherService singleton class using Node.js `fs.watch()`
+- **`sseEvent.ts`** - Event formatting utilities for SSE
+- **`types.ts`** - Event type definitions
+
+**File Watching Features:**
+- Monitors `~/.claude/projects/` recursively with singleton pattern
+- Event types: `connected`, `project_changed`, `session_changed`, `heartbeat`
+- Heartbeat mechanism (30s intervals) for connection health monitoring
+- Automatic cleanup on client disconnection with proper abort handling
+- Uses Hono's `streamSSE()` for efficient server-sent event streaming

 ## Data Validation

 ### Conversation Schema (`src/lib/conversation-schema/`)

-Modular Zod schemas handle different conversation entry types:
+The schema system uses a modular Zod architecture for type-safe conversation parsing:

- **Entry Types**: User, Assistant, System, Summary
- **Content Types**: Text, Tool Use, Tool Result, Thinking
- **Validation**: Strict type checking with fallback parsing
+#### Schema Organization
+
+```text
+conversation-schema/
+├── index.ts              # Main union schema
+├── content/              # Content type schemas
+│   ├── TextContentSchema.ts
+│   ├── ToolUseContentSchema.ts
+│   ├── ToolResultContentSchema.ts

+    ├── CommonToolSchema.ts
+    ├── StructuredPatchSchema.ts
+    └── TodoSchema.ts
+```
+
+#### Key Features
+
+- **Union Types**: `ConversationSchema` combines all entry types
+- **Incremental Parsing**: Graceful handling of malformed JSONL lines
+- **Content Validation**: Strict typing for different content formats
+- **Tool Support**: Dedicated schemas for Claude Code tools
+- **Type Safety**: Full TypeScript inference throughout the stack

 ### Command Detection

-Special XML-like command parsing for enhanced display:
+Advanced XML-like command parsing for enhanced conversation display:

 ```typescript
+// src/server/service/parseCommandXml.ts
 parseCommandXml(content: string) // Extracts command names and arguments
 ```

+Supports various command formats:
+- Slash commands (`/save`, `/edit`)
+- Local commands with arguments
+- Structured command detection for better UX

-### State Management
+### State Management Architecture

- **Server State**: TanStack Query with suspense boundaries
- **Client State**: Jotai atoms for UI state (filters, sidebar state)
- **Real-time**: Server-Sent Events with automatic reconnection
+#### Server State (TanStack Query)
+- **`useProjects`** - Project listing with caching
+- **`useProject`** - Individual project details and sessions
+- **`useSession`** - Conversation data fetching
+- **Suspense Integration**: Progressive loading with error boundaries
+- **Cache Management**: Automatic invalidation on SSE events

-### Type Safety
+#### Client State (Jotai Atoms)
+```text
+src/app/projects/[projectId]/store/filterAtoms.ts
+├── sessionFilterAtom     # Session filtering state
+├── searchTermAtom        # Search input state
+└── sortOrderAtom         # Session sorting preference
+```

- **API Types**: Generated from Hono route definitions
- **Schemas**: Zod validation with TypeScript inference
- **Build-time**: Strict TypeScript configuration via `@tsconfig/strictest`
+#### Real-time State (Server-Sent Events)
+- **`useServerEvents`** - SSE connection hook
+- **Auto-reconnection**: Handles connection drops gracefully
+- **Event Processing**: `project_changed`, `session_changed`, heartbeat
+- **Query Invalidation**: Automatic cache refresh on file changes
+
+### Type Safety System
+
+- **API Types**: Full inference from Hono route definitions to React components
+- **Schema Validation**: Runtime and compile-time type checking with Zod
+- **Build Configuration**: `@tsconfig/strictest` for maximum type safety
+- **Error Boundaries**: Typed error handling throughout the component tree
+
+### Hook Patterns
+
+#### Data Fetching Hooks
+```typescript
+// Custom hooks following consistent patterns
+useProjects()           // → { data, isLoading, error }
+useProject(projectId)   // → { project, sessions, isLoading }
+useSession(projectId, sessionId) // → { session, conversations, isLoading }
+```
+
+#### Real-time Hooks
+```typescript
+useServerEvents()       // → SSE connection management
+useSidechain()         // → Modal state management
+```

 ## Code Conventions

-### File Organization
+### File Organization Patterns

- **Services**: Business logic in `src/server/service/`
- **Components**: UI components with co-located styles
- **Schemas**: Modular Zod schemas with clear interfaces
- **Hooks**: Custom hooks for data fetching and state management
+- **Services**: Business logic organized by domain (`project/`, `session/`, `events/`)
+- **Components**: Co-located with hooks, stores, and services in feature directories
+- **Schemas**: Modular Zod schemas with clear separation of concerns
+- **Hooks**: Custom hooks grouped by functionality and data dependency
+- **Types**: TypeScript types inferred from Zod schemas where possible

 ### Naming Conventions

- **Files**: `kebab-case.ts`
- **Components**: `PascalCase`
- **Functions**: `camelCase`
- **Constants**: `SCREAMING_SNAKE_CASE`
+- **Files**: `camelCase.ts` for most files, `PascalCase.tsx` for React components
+- **Components**: `PascalCase` (e.g., `SessionPageContent.tsx`)
+- **Functions**: `camelCase` (e.g., `getProject`, `parseJsonl`)
+- **Constants**: `SCREAMING_SNAKE_CASE` (e.g., `PROJECTS_BASE_PATH`)
+- **Hooks**: `use` prefix (e.g., `useProject`, `useServerEvents`)
+- **Atoms**: Suffix with `Atom` (e.g., `sessionFilterAtom`)

-### Code Style
+### Code Style (Biome Configuration)

- **Formatter**: Biome (replaces Prettier)
- **Linter**: Biome (replaces ESLint)
- **Config**: Extends `@tsconfig/strictest` for maximum type safety
+**Biome replaces both ESLint and Prettier** with a single, fast tool:
+
+```json
+{
+  "formatter": {
+    "enabled": true,
+    "indentStyle": "space"    // 2-space indentation
+  },
+  "javascript": {
+    "formatter": {
+      "quoteStyle": "double"  // Double quotes for strings
+    }
+  },
+  "assist": {
+    "actions": {
+      "source": {
+        "organizeImports": "on" // Auto-organize imports
+      }
+    }
+  }
+}
+```
+
+**Key Style Rules:**
+- Double quotes for strings
+- 2-space indentation
+- Automatic import organization
+- Biome recommended linting rules
+- TypeScript strict mode via `@tsconfig/strictest`
