+
+This file provides guidance to AI Agents when working with code in this repository.
+
+## Taskfile (Recommended)
+
+This project uses [Task](https://taskfile.dev/) as a unified command runner. All build, dev, test, lint, and docker commands can be run from the repo root via `task <command>`. Run `task --list` to see all available commands.
+
+Task `desc:` fields should describe **what** the task does, not **how** it does it. Keep them generic and stable: don't reference implementation details like aliases, internal helpers, mode flags, or which other task delegates to which. The description is for users picking a command from `task --list`, not a changelog of refactors.
+
+### Quick Reference
+- `task install` — install all dependencies
+- `task dev` — start backend + frontend concurrently
+- `task dev:all` — start backend + frontend + engine concurrently
+- `task build` — build all components
+- `task test` — run all tests (backend + frontend + engine)
+- `task lint` — run all linters
+- `task format` — auto-fix formatting across all components
+- `task check` — full quality gate (lint + typecheck + test)
+- `task clean` — clean all build artifacts
+- `task docker:build` — build standard Docker image
+- `task docker:up` — start Docker compose stack
+
+## Common Development Commands
+
+### Build and Test
+- **Build project**: `task build`
+- **Run backend locally**: `task backend:dev`
+- **Run all tests**: `task test` (or individually: `task backend:test`, `task frontend:test`, `task engine:test`)
+- **Docker integration tests**: `./test.sh` (builds all Docker variants and runs comprehensive tests)
+- **Code formatting**: `task format` (or `task backend:format` for Java only)
+- **Full quality gate**: `task check` (runs lint + typecheck + test across all components)
+
+After modifying any files in the project, you must run the relevant `task check` command that covers that area of the code. For example, when editing frontend files run `task frontend:check`; for Python engine files run `task engine:check`; for Java backend files run `task backend:check`.
+
+### Docker Development
+- **Build standard**: `task docker:build` (or `docker build -t stirling-pdf -f docker/embedded/Dockerfile .`)
+- **Build fat version**: `task docker:build:fat`
+- **Build ultra-lite**: `task docker:build:ultra-lite`
+- **Start compose stack**: `task docker:up` (or `task docker:up:fat`, `task docker:up:ultra-lite`)
+- **Stop compose stack**: `task docker:down`
+- **View logs**: `task docker:logs`
+- **Example compose files**: Located in `exampleYmlFiles/` directory
+
+### Security Mode Development
+Set `DOCKER_ENABLE_SECURITY=true` environment variable to enable security features during development. This is required for testing the full version locally.
+
+### Python Development (AI Engine)
+
+The engine is a Python reasoning service for Stirling: it plans and interprets work, but it does not own durable state, and it does not execute Stirling PDF operations directly. Keep the service narrow: typed contracts in, typed contracts out, with AI only where it adds reasoning value. The frontend calls the Python engine via Java as a proxy.
+
+#### Python Commands
+All engine commands run from the repo root using Task:
+- `task engine:check` — run all checks (typecheck + lint + format-check + test)
+- `task engine:fix` — auto-fix lint + formatting
+- `task engine:install` — install Python dependencies via uv
+- `task engine:dev` — start FastAPI with hot reload (localhost:5001)
+- `task engine:test` — run pytest
+- `task engine:lint` — run ruff linting
+- `task engine:typecheck` — run pyright
+- `task engine:format` — format code with ruff
+- `task engine:tool-models` — generate `tool_models.py` from the Java OpenAPI spec
+
+The project structure is defined in `engine/pyproject.toml`. Any new dependencies should be listed there, followed by running `task engine:install`.
+
+#### Python Code Style
+- Keep `task engine:check` passing.
+- Use modern Python when it improves clarity.
+- Prefer explicit names to cleverness.
+- Avoid nested functions and nested classes unless the language construct requires them.
+- Prefer composition to inheritance when combining concepts.
+- Avoid speculative abstractions. Add a layer only when it removes real duplication or clarifies lifecycle.
+- Add comments sparingly and only when they explain non-obvious intent.
+
+#### Python Typing and Models
+- Deserialize into Pydantic models as early as possible.
+- Serialize from Pydantic models as late as possible.
+- Do not pass raw `dict[str, Any]` or `dict[str, object]` across important boundaries when a typed model can exist instead.
+- Avoid `Any` wherever possible.
+- Avoid `cast()` wherever possible (reconsider the structure first).
+- All shared models should subclass `stirling.models.ApiModel` so the service behaves consistently.
+- Do not use string literals for any type annotations, including `cast()`.
+
+#### Python Configuration
+- Keep application-owned configuration in `stirling.config`.
+- Only add `STIRLING_*` environment variables that the engine itself truly owns.
+- Do not mirror third-party provider environment variables unless the engine is actually interpreting them.
+- Let `pydantic-ai` own provider authentication configuration when possible.
+
+#### Python Architecture
+
+**Package roles:**
+- `stirling.contracts`: request/response models and shared typed workflow contracts. If a shape crosses a module or service boundary, it probably belongs here.
+- `stirling.models`: shared model primitives and generated tool models.
+- `stirling.agents`: reasoning modules for individual capabilities.
+- `stirling.api`: HTTP layer, dependency access, and app startup wiring.
+- `stirling.services`: shared runtime and non-AI infrastructure.
+- `stirling.config`: application-owned settings.
+
+**Source of truth:**
+- `stirling.models.tool_models` is the source of truth for operation IDs and parameter models.
+- Do not duplicate operation lists if they can be derived from `tool_models.OPERATIONS`.
+- Do not hand-maintain parallel parameter schemas when the generated tool models already define them.
+- If a tool ID must match a parameter model, validate that relationship explicitly in code.
+
+**Boundaries:**
+- Keep the API layer thin. Route modules should bind requests, resolve dependencies, and call agents or services. They should not contain business logic.
+- Keep agents focused on one reasoning domain. They should not own FastAPI routing, persistence, or execution of Stirling operations.
+- Build long-lived runtime objects centrally at startup when possible rather than reconstructing heavy AI objects per request.
+- If an agent delegates to another agent, the delegated agent should remain the source of truth for its own domain output.
+
+#### Python AI Usage
+- The system must work with any AI, including self-hosted models. We require that the models support structured outputs, but should minimise model-specific code beyond that.
+- Use AI for reasoning-heavy outputs, not deterministic glue.
+- Do not ask the model to invent data that Python can derive safely.
+- Do not fabricate fallback user-facing copy in code to hide incomplete model output.
+- AI output schemas should be impossible to instantiate incorrectly.
+  - Do not require the model to keep separate structures in sync. For example, instead of generating two lists which must be the same length, generate one list of a model containing the same data.
+  - Prefer Python to derive deterministic follow-up structure from a valid AI result.
+- Use `NativeOutput(...)` for structured model outputs.
+- Use `ToolOutput(...)` when the model should select and call delegate functions.
+
+#### Python Testing
+- Test contracts directly.
+- Test agents directly where behaviour matters.
+- Test API routes as thin integration points.
+- Prefer dependency overrides or startup-state seams to monkeypatching random globals.
+
+### Frontend Development
+- **Frontend dev server**: `task frontend:dev` — requires backend on localhost:8080
+- **Tech Stack**: Vite + React + TypeScript + Mantine UI + TailwindCSS
+- **Proxy Configuration**: Vite proxies `/api/*` calls to backend (localhost:8080)
+- **Build Process**: DO NOT run build scripts manually - builds are handled by CI/CD pipelines
+- **Package Installation**: `task frontend:install`
+- **Deployment Options**:
+  - **Desktop App**: `task desktop:build`
+  - **Web Server**: `task frontend:build` then serve dist/ folder
+  - **Development**: `task desktop:dev` for desktop dev mode
+
+#### Environment Variables
+- All `VITE_*` variables must be declared in the appropriate committed env file:
+  - `frontend/.env` — core, proprietary, and shared vars
+  - `frontend/.env.saas` — SaaS-only vars (layered on top of `.env` in SaaS mode)
+  - `frontend/.env.desktop` — desktop (Tauri)-only vars (layered on top of `.env` in desktop mode)
+- These files are committed to Git and must not contain private keys
+- Local overrides (API keys, machine-specific settings) go in uncommitted sibling `.env.local` / `.env.saas.local` / `.env.desktop.local` files — Vite automatically layers them on top
+- Never use `|| 'hardcoded-fallback'` inline — put defaults in the committed env files
+- `task frontend:prepare` creates empty `.local` override files on first run; pass `MODE=saas` or `MODE=desktop` to also create the mode-specific `.local` file
+- Prepare runs automatically as a dependency of all `dev*`, `build*`, and `desktop*` tasks
+- See `frontend/README.md#environment-variables` for full documentation
+
+#### Import Paths - CRITICAL
+**ALWAYS use `@app/*` for imports.** Do not use `@core/*` or `@proprietary/*` unless explicitly wrapping/extending a lower layer implementation.
+
+For a broader explanation of the frontend layering and override architecture, see [frontend/DeveloperGuide.md](frontend/DeveloperGuide.md).
+
+```typescript
+// ✅ CORRECT - Use @app/* for all imports
+import { AppLayout } from "@app/components/AppLayout";
+import { useFileContext } from "@app/contexts/FileContext";
+import { FileContext } from "@app/contexts/FileContext";
+
+// ❌ WRONG - Do not use @core/* or @proprietary/* in normal code
+import { AppLayout } from "@core/components/AppLayout";
+import { useFileContext } from "@proprietary/contexts/FileContext";
+```
+
+**Only use explicit aliases when:**
+- Building layer-specific override that wraps a lower layer's component
+- Example: `import { AppProviders as CoreAppProviders } from "@core/components/AppProviders"` when creating proprietary/AppProviders.tsx that extends the core version
+
+The `@app/*` alias automatically resolves to the correct layer based on build target (core/proprietary/desktop) and handles the fallback cascade.
+
+#### Component Override Pattern (Stub/Shadow)
+Use this pattern for desktop-specific or proprietary-specific features WITHOUT runtime checks or conditionals.
+
+**How it works:**
+1. Core defines stub component (returns null or no-op)
+2. Desktop/proprietary overrides with same path/name
+3. Core imports via `@app/*` - higher layer "shadows" core in those builds
+4. No `@ts-ignore`, no `isTauri()` checks, no runtime conditionals!
+
+**Example - Desktop-specific footer:**
+
+```typescript
+// core/components/rightRail/RightRailFooterExtensions.tsx (stub)
+interface RightRailFooterExtensionsProps {
+  className?: string;
+}
+
+export function RightRailFooterExtensions(_props: RightRailFooterExtensionsProps) {
+  return null; // Stub - does nothing in web builds
+}
+```
+
+```tsx
+// desktop/components/rightRail/RightRailFooterExtensions.tsx (real implementation)
+import { Box } from '@mantine/core';
+import { BackendHealthIndicator } from '@app/components/BackendHealthIndicator';
+
+interface RightRailFooterExtensionsProps {
+  className?: string;
+}
+
+export function RightRailFooterExtensions({ className }: RightRailFooterExtensionsProps) {
+  return (
+    <Box className={className}>
+      <BackendHealthIndicator />
+    </Box>
+  );
+}
+```
+
+```tsx
+// core/components/shared/RightRail.tsx (usage - works in ALL builds)
+import { RightRailFooterExtensions } from '@app/components/rightRail/RightRailFooterExtensions';
+
+export function RightRail() {
+  return (
+    <div>
+      {/* In web builds: renders nothing (stub returns null) */}
+      {/* In desktop builds: renders BackendHealthIndicator */}
+      <RightRailFooterExtensions className="right-rail-footer" />
+    </div>
+  );
+}
+```
+
+**Build resolution:**
+- **Core build**: `@app/*` → `core/*` → Gets stub (returns null)
+- **Desktop build**: `@app/*` → `desktop/*` → Gets real implementation (shadows core)
+
+**Benefits:**
+- No runtime checks or feature flags
+- Type-safe across all builds
+- Clean, readable code
+- Build-time optimization (dead code elimination)
+
+#### Multi-Tool Workflow Architecture
+Frontend designed for **stateful document processing**:
+- Users upload PDFs once, then chain tools (split → merge → compress → view)
+- File state and processing results persist across tool switches
+- No file reloading between tools - performance critical for large PDFs (up to 100GB+)
+
+#### FileContext - Central State Management
+**Location**: `frontend/src/core/contexts/FileContext.tsx`
+- **Active files**: Currently loaded PDFs and their variants
+- **Tool navigation**: Current mode (viewer/pageEditor/fileEditor/toolName)
+- **Memory management**: PDF document cleanup, blob URL lifecycle, Web Worker management
+- **IndexedDB persistence**: File storage with thumbnail caching
+- **Preview system**: Tools can preview results (e.g., Split → Viewer → back to Split) without context pollution
+
+**Critical**: All file operations go through FileContext. Don't bypass with direct file handling.
+
+#### Processing Services
+- **enhancedPDFProcessingService**: Background PDF parsing and manipulation
+- **thumbnailGenerationService**: Web Worker-based with main-thread fallback
+- **fileStorage**: IndexedDB with LRU cache management
+
+#### Memory Management Strategy
+**Why manual cleanup exists**: Large PDFs (up to 100GB+) through multiple tools accumulate:
+- PDF.js documents that need explicit .destroy() calls
+- Blob URLs from tool outputs that need revocation
+- Web Workers that need termination
+Without cleanup: browser crashes with memory leaks.
+
+#### Tool Development
+
+**Architecture**: Modular hook-based system with clear separation of concerns:
+
+- **useToolOperation** (`frontend/src/core/hooks/tools/shared/useToolOperation.ts`): Main orchestrator hook
+  - Coordinates all tool operations with consistent interface
+  - Integrates with FileContext for operation tracking
+  - Handles validation, error handling, and UI state management
+
+- **Supporting Hooks**:
+  - **useToolState**: UI state management (loading, progress, error, files)
+  - **useToolApiCalls**: HTTP requests and file processing
+  - **useToolResources**: Blob URLs, thumbnails, ZIP downloads
+
+- **Utilities**:
+  - **toolErrorHandler**: Standardized error extraction and i18n support
+  - **toolResponseProcessor**: API response handling (single/zip/custom)
+  - **toolOperationTracker**: FileContext integration utilities
+
+**Three Tool Patterns**:
+
+**Pattern 1: Single-File Tools** (Individual processing)
+- Backend processes one file per API call
+- Set `multiFileEndpoint: false`
+- Examples: Compress, Rotate
+```typescript
+return useToolOperation({
+  operationType: 'compress',
+  endpoint: '/api/v1/misc/compress-pdf',
+  buildFormData: (params, file: File) => { /* single file */ },
+  multiFileEndpoint: false,
+});
+```
+
+**Pattern 2: Multi-File Tools** (Batch processing)
+- Backend accepts `MultipartFile[]` arrays in single API call
+- Set `multiFileEndpoint: true`
+- Examples: Split, Merge, Overlay
+```typescript
+return useToolOperation({
+  operationType: 'split',
+  endpoint: '/api/v1/general/split-pages',
+  buildFormData: (params, files: File[]) => { /* all files */ },
+  multiFileEndpoint: true,
+  filePrefix: 'split_',
+});
+```
+
+**Pattern 3: Complex Tools** (Custom processing)
+- Tools with complex routing logic or non-standard processing
+- Provide `customProcessor` for full control
+- Examples: Convert, OCR
+```typescript
+return useToolOperation({
+  operationType: 'convert',
+  customProcessor: async (params, files) => { /* custom logic */ },
+});
+```
+
+**Benefits**:
+- **No Timeouts**: Operations run until completion (supports 100GB+ files)
+- **Consistent**: All tools follow same pattern and interface
+- **Maintainable**: Single responsibility hooks, easy to test and modify
+- **i18n Ready**: Built-in internationalization support
+- **Type Safe**: Full TypeScript support with generic interfaces
+- **Memory Safe**: Automatic resource cleanup and blob URL management
+
+## Architecture Overview
+
+### Project Structure
+- **Backend**: Spring Boot application
+- **Frontend**: React-based SPA in `/frontend` directory
+  - **File Storage**: IndexedDB for client-side file persistence and thumbnails
+  - **Internationalization**: JSON-based translations (converted from backend .properties)
+- **PDF Processing**: PDFBox for core PDF operations, LibreOffice for conversions, PDF.js for client-side rendering
+- **Security**: Spring Security with optional authentication (controlled by `DOCKER_ENABLE_SECURITY`)
+- **Configuration**: YAML-based configuration with environment variable overrides
+
+### Controller Architecture
+- **API Controllers** (`src/main/java/.../controller/api/`): REST endpoints for PDF operations
+  - Organized by function: converters, security, misc, pipeline
+  - Follow pattern: `@RestController` + `@RequestMapping("/api/v1/...")`
+
+### Key Components
+- **SPDFApplication.java**: Main application class with desktop UI and browser launching logic
+- **ConfigInitializer**: Handles runtime configuration and settings files
+- **Pipeline System**: Automated PDF processing workflows via `PipelineController`
+- **Security Layer**: Authentication, authorization, and user management (when enabled)
+
+### Frontend Directory Structure
+The frontend is organized with a clear separation of concerns:
+
+- **`frontend/src/core/`**: Main application code (shared, production-ready components)
+  - **`core/components/`**: React components organized by feature
+    - `core/components/tools/`: Individual PDF tool implementations
+    - `core/components/viewer/`: PDF viewer components

+### Component Architecture
+- **Static Assets**: CSS, JS, and resources in `src/main/resources/static/` (legacy) + `frontend/public/` (modern)
+- **Internationalization**:
+  - Backend: `messages_*.properties` files
+  - Frontend: JSON files in `frontend/public/locales/` (converted from .properties)

+
+### Configuration Modes
+- **Ultra-lite**: Basic PDF operations only
+- **Standard**: Full feature set
+- **Fat**: Pre-downloaded dependencies for air-gapped environments
+- **Security Mode**: Adds authentication, user management, and enterprise features
+
+### Testing Strategy
+- **Integration Tests**: Cucumber tests in `testing/cucumber/`
+- **Docker Testing**: `test.sh` validates all Docker variants
+- **Manual Testing**: No unit tests currently - relies on UI and API testing
+
+## Development Workflow
+
+1. **Local Development** (using Taskfile):
+   - Backend + frontend: `task dev`
+   - All services (including AI engine): `task dev:all`
+   - Or individually: `task backend:dev` (localhost:8080), `task frontend:dev` (localhost:5173), `task engine:dev` (localhost:5001)
+2. **Quality Gate**: Run `task check` before submitting PRs
+3. **Docker Testing**: Use `./test.sh` for full Docker integration tests
+4. **Code Style**: Spotless enforces Google Java Format automatically (`task backend:format`)
+5. **Translations**:
+   - Backend: Use helper scripts in `/scripts` for multi-language updates
+   - Frontend: Update JSON files in `frontend/public/locales/` or use conversion script
+6. **Documentation**: API docs auto-generated and available at `/swagger-ui/index.html`
+
+## Frontend Architecture Status
+
+- **Core Status**: React SPA architecture complete with multi-tool workflow support
+- **State Management**: FileContext handles all file operations and tool navigation
+- **File Processing**: Production-ready with memory management for large PDF workflows (up to 100GB+)
+- **Tool Integration**: Modular hook architecture with `useToolOperation` orchestrator
+  - Individual hooks: `useToolState`, `useToolApiCalls`, `useToolResources`
+  - Utilities: `toolErrorHandler`, `toolResponseProcessor`, `toolOperationTracker`
+  - Pattern: Each tool creates focused operation hook, UI consumes state/actions
+- **Preview System**: Tool results can be previewed without polluting file context (Split tool example)
+- **Performance**: Web Worker thumbnails, IndexedDB persistence, background processing
+
+## Translation Rules
+
+- **CRITICAL**: Always update translations in `en-GB` only, never `en-US`
+- Translation files are located in `frontend/public/locales/`
+
+## Important Notes
+
+- **Java Version**: Minimum JDK 21, supports and recommends JDK 25
+- **Lombok**: Used extensively - ensure IDE plugin is installed
+- **File Persistence**:
+  - **Backend**: Designed to be stateless - files are processed in memory/temp locations only
+  - **Frontend**: Uses IndexedDB for client-side file storage and caching (with thumbnails)

-## Common Development Commands
-
-### Build and Test
- **Build project**: `./gradlew clean build`
- **Run locally**: `./gradlew bootRun`
- **Full test suite**: `./test.sh` (builds all Docker variants and runs comprehensive tests)
- **Code formatting**: `./gradlew spotlessApply` (runs automatically before compilation)
-
-### Docker Development
- **Build ultra-lite**: `docker build -t stirlingtools/stirling-pdf:latest-ultra-lite -f ./Dockerfile.ultra-lite .`
- **Build standard**: `docker build -t stirlingtools/stirling-pdf:latest -f ./Dockerfile .`
- **Build fat version**: `docker build -t stirlingtools/stirling-pdf:latest-fat -f ./Dockerfile.fat .`
- **Example compose files**: Located in `exampleYmlFiles/` directory
-
-### Security Mode Development
-Set `DOCKER_ENABLE_SECURITY=true` environment variable to enable security features during development. This is required for testing the full version locally.
-
-### Frontend Development
- **Frontend dev server**: `cd frontend && npm run dev` (requires backend on localhost:8080)
- **Tech Stack**: Vite + React + TypeScript + Mantine UI + TailwindCSS
- **Proxy Configuration**: Vite proxies `/api/*` calls to backend (localhost:8080)
- **Build Process**: DO NOT run build scripts manually - builds are handled by CI/CD pipelines
- **Package Installation**: DO NOT run npm install commands - package management handled separately
- **Deployment Options**:
-  - **Desktop App**: `npm run tauri-build` (native desktop application)
-  - **Web Server**: `npm run build` then serve dist/ folder
-  - **Development**: `npm run tauri-dev` for desktop dev mode
-
-#### Import Paths - CRITICAL
-**ALWAYS use `@app/*` for imports.** Do not use `@core/*` or `@proprietary/*` unless explicitly wrapping/extending a lower layer implementation.
-
-```typescript
-// ✅ CORRECT - Use @app/* for all imports
-import { AppLayout } from "@app/components/AppLayout";
-import { useFileContext } from "@app/contexts/FileContext";
-import { FileContext } from "@app/contexts/FileContext";
-
-// ❌ WRONG - Do not use @core/* or @proprietary/* in normal code
-import { AppLayout } from "@core/components/AppLayout";
-import { useFileContext } from "@proprietary/contexts/FileContext";
-```
-
-**Only use explicit aliases when:**
- Building layer-specific override that wraps a lower layer's component
- Example: `import { AppProviders as CoreAppProviders } from "@core/components/AppProviders"` when creating proprietary/AppProviders.tsx that extends the core version
-
-The `@app/*` alias automatically resolves to the correct layer based on build target (core/proprietary/desktop) and handles the fallback cascade.
-
-#### Component Override Pattern (Stub/Shadow)
-Use this pattern for desktop-specific or proprietary-specific features WITHOUT runtime checks or conditionals.
-
-**How it works:**
-1. Core defines stub component (returns null or no-op)
-2. Desktop/proprietary overrides with same path/name
-3. Core imports via `@app/*` - higher layer "shadows" core in those builds
-4. No `@ts-ignore`, no `isTauri()` checks, no runtime conditionals!
-
-**Example - Desktop-specific footer:**
-
-```typescript
-// core/components/rightRail/RightRailFooterExtensions.tsx (stub)
-interface RightRailFooterExtensionsProps {
-  className?: string;
-}
-
-export function RightRailFooterExtensions(_props: RightRailFooterExtensionsProps) {
-  return null; // Stub - does nothing in web builds
-}
-```
-
-```typescript
-// desktop/components/rightRail/RightRailFooterExtensions.tsx (real implementation)
-import { Box } from '@mantine/core';
-import { BackendHealthIndicator } from '@app/components/BackendHealthIndicator';
-
-interface RightRailFooterExtensionsProps {
-  className?: string;
-}
-
-export function RightRailFooterExtensions({ className }: RightRailFooterExtensionsProps) {
-  return (
-    <Box className={className}>
-      <BackendHealthIndicator />
-    </Box>
-  );
-}
-```
-
-```typescript
-// core/components/shared/RightRail.tsx (usage - works in ALL builds)
-import { RightRailFooterExtensions } from '@app/components/rightRail/RightRailFooterExtensions';
-
-export function RightRail() {
-  return (
-    <div>
-      {/* In web builds: renders nothing (stub returns null) */}
-      {/* In desktop builds: renders BackendHealthIndicator */}
-      <RightRailFooterExtensions className="right-rail-footer" />
-    </div>
-  );
-}
-```
-
-**Build resolution:**
- **Core build**: `@app/*` → `core/*` → Gets stub (returns null)
- **Desktop build**: `@app/*` → `desktop/*` → Gets real implementation (shadows core)
-
-**Benefits:**
- No runtime checks or feature flags
- Type-safe across all builds
- Clean, readable code
- Build-time optimization (dead code elimination)
-
-#### Multi-Tool Workflow Architecture
-Frontend designed for **stateful document processing**:
- Users upload PDFs once, then chain tools (split → merge → compress → view)
- File state and processing results persist across tool switches
- No file reloading between tools - performance critical for large PDFs (up to 100GB+)
-
-#### FileContext - Central State Management
-**Location**: `frontend/src/core/contexts/FileContext.tsx`
- **Active files**: Currently loaded PDFs and their variants
- **Tool navigation**: Current mode (viewer/pageEditor/fileEditor/toolName)
- **Memory management**: PDF document cleanup, blob URL lifecycle, Web Worker management
- **IndexedDB persistence**: File storage with thumbnail caching
- **Preview system**: Tools can preview results (e.g., Split → Viewer → back to Split) without context pollution
-
-**Critical**: All file operations go through FileContext. Don't bypass with direct file handling.
-
-#### Processing Services
- **enhancedPDFProcessingService**: Background PDF parsing and manipulation
- **thumbnailGenerationService**: Web Worker-based with main-thread fallback
- **fileStorage**: IndexedDB with LRU cache management
-
-#### Memory Management Strategy
-**Why manual cleanup exists**: Large PDFs (up to 100GB+) through multiple tools accumulate:
- PDF.js documents that need explicit .destroy() calls
- Blob URLs from tool outputs that need revocation
- Web Workers that need termination
-Without cleanup: browser crashes with memory leaks.
-
-#### Tool Development
-
-**Architecture**: Modular hook-based system with clear separation of concerns:
-
- **useToolOperation** (`frontend/src/core/hooks/tools/shared/useToolOperation.ts`): Main orchestrator hook
-  - Coordinates all tool operations with consistent interface
-  - Integrates with FileContext for operation tracking
-  - Handles validation, error handling, and UI state management
-
- **Supporting Hooks**:
-  - **useToolState**: UI state management (loading, progress, error, files)
-  - **useToolApiCalls**: HTTP requests and file processing
-  - **useToolResources**: Blob URLs, thumbnails, ZIP downloads
-
- **Utilities**:
-  - **toolErrorHandler**: Standardized error extraction and i18n support
-  - **toolResponseProcessor**: API response handling (single/zip/custom)
-  - **toolOperationTracker**: FileContext integration utilities
-
-**Three Tool Patterns**:
-
-**Pattern 1: Single-File Tools** (Individual processing)
- Backend processes one file per API call
- Set `multiFileEndpoint: false`
- Examples: Compress, Rotate
-```typescript
-return useToolOperation({
-  operationType: 'compress',
-  endpoint: '/api/v1/misc/compress-pdf',
-  buildFormData: (params, file: File) => { /* single file */ },
-  multiFileEndpoint: false,
-});
-```
-
-**Pattern 2: Multi-File Tools** (Batch processing)
- Backend accepts `MultipartFile[]` arrays in single API call
- Set `multiFileEndpoint: true`
- Examples: Split, Merge, Overlay
-```typescript
-return useToolOperation({
-  operationType: 'split',
-  endpoint: '/api/v1/general/split-pages',
-  buildFormData: (params, files: File[]) => { /* all files */ },
-  multiFileEndpoint: true,
-  filePrefix: 'split_',
-});
-```
-
-**Pattern 3: Complex Tools** (Custom processing)
- Tools with complex routing logic or non-standard processing
- Provide `customProcessor` for full control
- Examples: Convert, OCR
-```typescript
-return useToolOperation({
-  operationType: 'convert',
-  customProcessor: async (params, files) => { /* custom logic */ },
-});
-```
-
-**Benefits**:
- **No Timeouts**: Operations run until completion (supports 100GB+ files)
- **Consistent**: All tools follow same pattern and interface
- **Maintainable**: Single responsibility hooks, easy to test and modify
- **i18n Ready**: Built-in internationalization support
- **Type Safe**: Full TypeScript support with generic interfaces
- **Memory Safe**: Automatic resource cleanup and blob URL management
-
-## Architecture Overview
-
-### Project Structure
- **Backend**: Spring Boot application
- **Frontend**: React-based SPA in `/frontend` directory
-  - **File Storage**: IndexedDB for client-side file persistence and thumbnails
-  - **Internationalization**: JSON-based translations (converted from backend .properties)
- **PDF Processing**: PDFBox for core PDF operations, LibreOffice for conversions, PDF.js for client-side rendering
- **Security**: Spring Security with optional authentication (controlled by `DOCKER_ENABLE_SECURITY`)
- **Configuration**: YAML-based configuration with environment variable overrides
-
-### Controller Architecture
- **API Controllers** (`src/main/java/.../controller/api/`): REST endpoints for PDF operations
-  - Organized by function: converters, security, misc, pipeline
-  - Follow pattern: `@RestController` + `@RequestMapping("/api/v1/...")`
-
-### Key Components
- **SPDFApplication.java**: Main application class with desktop UI and browser launching logic
- **ConfigInitializer**: Handles runtime configuration and settings files
- **Pipeline System**: Automated PDF processing workflows via `PipelineController`
- **Security Layer**: Authentication, authorization, and user management (when enabled)
-
-### Frontend Directory Structure
-The frontend is organized with a clear separation of concerns:
-
- **`frontend/src/core/`**: Main application code (shared, production-ready components)
-  - **`core/components/`**: React components organized by feature
-    - `core/components/tools/`: Individual PDF tool implementations

-  - **`core/constants/`**: Application constants and configuration
-  - **`core/data/`**: Static data (tool taxonomy, etc.)
-  - **`core/services/`**: Business logic services (PDF processing, storage, etc.)
-
- **`frontend/src/desktop/`**: Desktop-specific (Tauri) code
- **`frontend/src/proprietary/`**: Proprietary/licensed features
- **`frontend/src-tauri/`**: Tauri (Rust) native desktop application code
- **`frontend/public/`**: Static assets served directly
-  - `public/locales/`: Translation JSON files
-
-### Component Architecture
- **Static Assets**: CSS, JS, and resources in `src/main/resources/static/` (legacy) + `frontend/public/` (modern)
- **Internationalization**:
-  - Backend: `messages_*.properties` files
-  - Frontend: JSON files in `frontend/public/locales/` (converted from .properties)
-  - Conversion Script: `scripts/convert_properties_to_json.py`
-
-### Configuration Modes
- **Ultra-lite**: Basic PDF operations only

+# File Sharing Feature - Architecture & Workflow
+
+## Overview
+
+The File Sharing feature enables users to store files server-side and share them with other registered users or via token-based share links. Files are stored using a pluggable storage provider (local filesystem or database) with optional quota enforcement.
+
+**Key Capabilities:**
+- Server-side file storage (upload, update, download, delete)
+- Optional history bundle and audit log attachments per file
+- Direct user-to-user sharing with access roles
+- Token-based share links (requires `system.frontendUrl`)
+- Optional email notifications for shares (requires `mail.enabled`)
+- Access audit trail (tracks who accessed a share link and how)
+- Automatic share link expiration
+- Storage quotas (per-user and total)
+- Pluggable storage backend (local filesystem or database BLOB)
+- Integration with the Shared Signing workflow
+
+## Architecture
+
+### Database Schema
+
+**`stored_files`**
+- One record per uploaded file
+- Stores file metadata (name, content type, size, storage key)
+- Optionally links to a history bundle and audit log as separate stored objects
+- `workflow_session_id` — nullable link to a `WorkflowSession` (signing feature)
+- `file_purpose` — enum classifying the file's role: `GENERIC`, `SIGNING_ORIGINAL`, `SIGNING_SIGNED`, `SIGNING_HISTORY`
+
+**`file_shares`**
+- One record per sharing relationship
+- Two share types, distinguished by which fields are set:
+  - **User share**: `shared_with_user_id` is set, `share_token` is null
+  - **Link share**: `share_token` is set (UUID), `shared_with_user_id` is null
+- `access_role` — `EDITOR`, `COMMENTER`, or `VIEWER`
+- `expires_at` — nullable expiration for link shares
+- `workflow_participant_id` — when set, marks this as a **workflow share** (hidden from the file manager, accessible only via workflow endpoints)
+
+**`file_share_accesses`**
+- One record per access event on a share link
+- Tracks: user, share link, access type (`VIEW` or `DOWNLOAD`), timestamp
+
+**`storage_cleanup_entries`**
+- Queue of storage keys to be deleted asynchronously
+- Used when a file is deleted but the physical storage object cleanup is deferred
+
+### Access Roles
+
+| Role | Can Read | Can Write |
+|------|----------|-----------|
+| `EDITOR` | ✅ | ✅ |
+| `COMMENTER` | ✅ | ❌ |
+| `VIEWER` | ✅ | ❌ |
+
+Default role when none is specified: `EDITOR`.
+
+Owners always have full access regardless of role.
+
+#### Role Semantics: COMMENTER vs VIEWER
+
+In the file storage layer, `COMMENTER` and `VIEWER` are equivalent — both grant read-only access and neither can replace file content. The distinction is meaningful in the **signing workflow** context:
+
+| Context | COMMENTER | VIEWER |
+|---------|-----------|--------|
+| File storage | Read only (same as VIEWER) | Read only |
+| Signing workflow | Can submit a signing action | Read only |
+
+`WorkflowParticipant.canEdit()` returns `true` for `COMMENTER` (and `EDITOR`) roles, which the signing workflow uses to determine if a participant can still submit a signature. Once a participant has signed or declined, their effective role is automatically downgraded to `VIEWER` regardless of their configured role.
+
+The rationale: "annotating" a document (submitting a signature) is not the same as "replacing" it. COMMENTER grants annotation rights without file-replacement rights.
+
+### Backend Architecture
+
+#### Service Layer
+
+**FileStorageService** (`1137 lines`)
+- Core file management service
+- Upload, update, download, and delete operations
+- User share management (share, revoke, leave)
+- Link share management (create, revoke, access)
+- Access recording and listing
+- Storage quota enforcement
+- Configuration feature gate checks
+
+**StorageCleanupService**
+- Scheduled daily: deletes orphaned storage keys from `storage_cleanup_entries`
+- Scheduled daily: purges expired share links from `file_shares`
+- Processes cleanup in batches of 50 entries
+
+#### Storage Providers
+
+**LocalStorageProvider**
+- Files stored on the filesystem under `storage.local.basePath` (default: `./storage`)
+- Storage key is a path relative to the base directory
+
+**DatabaseStorageProvider**
+- Files stored as BLOBs in `stored_file_blobs` table
+- No filesystem dependency
+
+Provider is selected at startup via `storage.provider: local | database`.
+
+#### Controller Layer
+
+**FileStorageController** (`/api/v1/storage`)
+- All endpoints require authentication
+- File CRUD and sharing operations
+
+### Data Flow
+
+```
+User uploads file → StorageProvider stores bytes → StoredFile record created
+       ↓
+Owner shares file → FileShare record created (user or link)
+       ↓
+Recipient accesses file → Access recorded → File bytes streamed
+```
+
+## File Operations
+
+### Upload File
+
+```bash
+POST /api/v1/storage/files
+Content-Type: multipart/form-data
+
+file: document.pdf                # Required — main file
+historyBundle: history.json       # Optional — version history
+auditLog: audit.json              # Optional — audit trail
+```
+
+**Response:**
+```json
+{
+  "id": 42,
+  "fileName": "document.pdf",
+  "contentType": "application/pdf",
+  "sizeBytes": 102400,
+  "owner": "alice",
+  "ownedByCurrentUser": true,
+  "accessRole": "editor",
+  "createdAt": "2025-01-01T12:00:00",
+  "updatedAt": "2025-01-01T12:00:00",
+  "sharedWithUsers": [],
+  "sharedUsers": [],
+  "shareLinks": []
+}
+```
+
+### Update File
+
+Replaces the file content. Only the owner can update.
+
+```bash
+PUT /api/v1/storage/files/{fileId}
+Content-Type: multipart/form-data
+
+file: document_v2.pdf
+historyBundle: history.json       # Optional
+auditLog: audit.json              # Optional
+```
+
+### List Files
+
+Returns all files owned by or shared with the current user. Workflow-shared files (signing participants) are excluded — those are accessible via signing endpoints only.
+
+```bash
+GET /api/v1/storage/files
+```
+
+Response is sorted by `createdAt` descending.
+
+### Download File
+
+```bash
+GET /api/v1/storage/files/{fileId}/download?inline=false
+```
+
+- `inline=false` (default) — `Content-Disposition: attachment`
+- `inline=true` — `Content-Disposition: inline` (for browser preview)
+
+### Delete File
+
+Only the owner can delete. All associated share links and their access records are deleted first, then the database record, then the physical storage object.
+
+```bash
+DELETE /api/v1/storage/files/{fileId}
+```
+
+## Sharing Operations
+
+### Share with User
+
+```bash
+POST /api/v1/storage/files/{fileId}/shares/users
+Content-Type: application/json
+
+{
+  "username": "bob",          # Username or email address
+  "accessRole": "editor"      # "editor", "commenter", or "viewer" (default: "editor")
+}
+```
+
+**Behaviour:**
+- If the target user exists: creates/updates a `FileShare` with `sharedWithUser` set
+- If `username` is an email address and the user doesn't exist: creates a share link and sends a notification email (requires `sharing.emailEnabled` and `sharing.linkEnabled`)
+- If the target user is the owner: returns 400
+- If sharing is disabled: returns 403
+
+### Revoke User Share
+
+Only the owner can revoke.
+
+```bash
+DELETE /api/v1/storage/files/{fileId}/shares/users/{username}
+```
+
+### Leave Shared File
+
+The recipient removes themselves from a shared file.
+
+```bash
+DELETE /api/v1/storage/files/{fileId}/shares/self
+```
+
+### Create Share Link
+
+Creates a token-based link for anonymous/authenticated access. Requires `sharing.linkEnabled` and `system.frontendUrl` to be configured.
+
+```bash
+POST /api/v1/storage/files/{fileId}/shares/links
+Content-Type: application/json
+
+{
+  "accessRole": "viewer"      # Optional (default: "editor")
+}
+```
+
+**Response:**
+```json
+{
+  "token": "550e8400-e29b-41d4-a716-446655440000",
+  "accessRole": "viewer",
+  "createdAt": "2025-01-01T12:00:00",
+  "expiresAt": "2025-01-04T12:00:00"
+}
+```
+
+Expiration is set to `now + sharing.linkExpirationDays` (default: 3 days).
+
+### Revoke Share Link
+
+```bash
+DELETE /api/v1/storage/files/{fileId}/shares/links/{token}
+```
+
+Also deletes all access records for that token.
+
+## Share Link Access
+
+### Download via Share Link
+
+Authentication is required (even for share links). Anonymous access is not permitted.
+
+```bash
+GET /api/v1/storage/share-links/{token}?inline=false
+```
+
+- Returns 401 if unauthenticated
+- Returns 403 if authenticated but link doesn't permit access
+- Returns 410 if the link has expired
+- Records a `FileShareAccess` entry on success
+
+> **Token-as-credential semantics:** Any authenticated user who holds the token can access the file — the token is the credential. If you need per-user access control (only a specific person can open it), use "Share with User" instead. Share links are appropriate for broader distribution where possession of the token implies authorization.
+
+### Get Share Link Metadata
+
+```bash
+GET /api/v1/storage/share-links/{token}/metadata
+```
+
+Returns file name, owner, access role, creation/expiry timestamps, and whether the current user owns the file.
+
+### List Accessed Share Links
+
+Returns the most recent access for each non-expired share link the current user has accessed.
+
+```bash
+GET /api/v1/storage/share-links/accessed
+```
+
+### List Accesses for a Link (Owner Only)
+
+```bash
+GET /api/v1/storage/files/{fileId}/shares/links/{token}/accesses
+```
+
+Returns per-user access history (username, VIEW/DOWNLOAD, timestamp), sorted descending by time.
+
+## Workflow Share Integration
+
+Signing workflow participants access documents via their own `WorkflowParticipant.shareToken`. No `FileShare` record is created for participants; access control is self-contained in the `WorkflowParticipant` entity.
+
+The `FileShare.workflow_participant_id` column and the `FileShare.isWorkflowShare()` method are **deprecated**. Legacy data (sessions created before this change) may still have `FileShare` records with `workflow_participant_id` set, which continue to work via the existing token lookup path in `UnifiedAccessControlService`. No new records are created.
+
+`GET /api/v1/storage/files` returns all files owned by or shared with the current user (via `FileShare`). Signing-session PDFs use the `file_purpose` field (`SIGNING_ORIGINAL`, `SIGNING_SIGNED`, etc.) to distinguish them from generic files. The file manager UI can filter on this field if needed.

+| GET | `/api/v1/storage/files/{id}/shares/links/{token}/accesses` | List share accesses | Required (owner) |
+
+## Configuration
+
+All storage settings live under the `storage:` key in `settings.yml`:
+
+```yaml
+storage:
+  enabled: true                  # Requires security.enableLogin = true
+  provider: local                # 'local' or 'database'
+  local:
+    basePath: './storage'        # Filesystem base directory (local provider only)
+  quotas:
+    maxStorageMbPerUser: -1      # Per-user storage cap in MB; -1 = unlimited
+    maxStorageMbTotal: -1        # Total storage cap in MB; -1 = unlimited
+    maxFileMb: -1                # Max size per upload (main + history + audit) in MB; -1 = unlimited
+  sharing:
+    enabled: false               # Master switch for all sharing (opt-in)
+    linkEnabled: false           # Enable token-based share links (requires system.frontendUrl)
+    emailEnabled: false          # Enable email notifications (requires mail.enabled)
+    linkExpirationDays: 3        # Days until share links expire
+```
+
+**Prerequisites:**
+- `storage.enabled` requires `security.enableLogin = true`
+- `sharing.linkEnabled` requires `system.frontendUrl` to be set (used to build share link URLs)
+- `sharing.emailEnabled` requires `mail.enabled = true`
+
+## Security Considerations
+
+### Access Control
+- All endpoints require authentication — there is no anonymous access
+- Owner-only operations enforced in service layer (not just controller)
+- `requireReadAccess` / `requireEditorAccess` checked on every download
+
+### Share Link Security
+- Tokens are UUIDs (random, not guessable)
+- Expiration enforced on every access
+- Expired links return HTTP 410 Gone
+- Revoked links delete all access records
+
+### Quota Enforcement
+- Checked before storing (not after)
+- Accounts for existing file size when replacing (only the delta counts)
+- Covers main file + history bundle + audit log in a single check
+
+## Automatic Cleanup
+
+`StorageCleanupService` runs two scheduled jobs daily:
+
+1. **Orphaned storage cleanup** — processes up to 50 `StorageCleanupEntry` records, deletes the physical storage object, then removes the entry. Failed attempts increment `attemptCount` for retry.
+
+2. **Expired share link cleanup** — deletes all `FileShare` records where `expiresAt` is in the past and `shareToken` is set.
+
+## Troubleshooting
+
+**"Storage is disabled":**
+- Check `storage.enabled: true` in settings
+- Verify `security.enableLogin: true`
+
+**"Share links are disabled":**
+- Check `sharing.linkEnabled: true`
+- Verify `system.frontendUrl` is set and non-empty
+
+**"Email sharing is disabled":**
+- Check `sharing.emailEnabled: true`
+- Verify `mail.enabled: true` and mail configuration
+
+**Signing-session PDF appearing in the general file list:**
+- This is expected — signing PDFs are accessible to owners and shared users
+- Filter by `file_purpose` (`SIGNING_ORIGINAL`, `SIGNING_SIGNED`) in the UI to distinguish them
+
+**Share link returns 410:**
+- Link has expired — check `expires_at` in `file_shares` table
+- Owner must create a new link
+
+### Debug Queries
+
+```sql
+-- List files and their share counts
+SELECT sf.stored_file_id, sf.original_filename, u.username as owner,
+       COUNT(DISTINCT fs.file_share_id) FILTER (WHERE fs.shared_with_user_id IS NOT NULL) as user_shares,
+       COUNT(DISTINCT fs.file_share_id) FILTER (WHERE fs.share_token IS NOT NULL) as link_shares
+FROM stored_files sf
+LEFT JOIN users u ON sf.owner_id = u.user_id
+LEFT JOIN file_shares fs ON fs.stored_file_id = sf.stored_file_id
+GROUP BY sf.stored_file_id, u.username;
+
+-- Check share link expiration
+SELECT share_token, access_role, created_at, expires_at,
+       expires_at < NOW() as is_expired
+FROM file_shares
+WHERE share_token IS NOT NULL;
+
+-- Check access history for a share link
+SELECT u.username, fsa.access_type, fsa.accessed_at
+FROM file_share_accesses fsa
+JOIN file_shares fs ON fsa.file_share_id = fs.file_share_id
+JOIN users u ON fsa.user_id = u.user_id
+WHERE fs.share_token = '{token}'
+ORDER BY fsa.accessed_at DESC;
+
+-- Pending cleanup entries
+SELECT storage_key, attempt_count, updated_at
+FROM storage_cleanup_entries
+ORDER BY updated_at ASC;
+```
+
+## Summary
+
+The File Sharing feature provides:
+- ✅ Server-side file storage with pluggable backend (local/database)
+- ✅ History bundle and audit log attachments per file
+- ✅ Direct user-to-user sharing with EDITOR/COMMENTER/VIEWER roles
+- ✅ Token-based share links with expiration
+- ✅ Optional email notifications for shares
+- ✅ Per-access audit trail for share links
+- ✅ Storage quotas (per-user, total, per-file)
+- ✅ Automatic cleanup of expired links and orphaned storage
+- ✅ Workflow integration (signing-session PDFs stored via same infrastructure; participant access via `WorkflowParticipant.shareToken`)

+# Shared Signing Feature - Architecture & Workflow
+
+## Overview
+
+The Shared Signing feature enables collaborative document signing workflows where a document owner can request signatures from multiple participants. Each participant receives a secure token to access the document, submit their digital signature (with optional wet signature overlay), and track the signing progress.
+
+**Key Capabilities:**
+- Multi-participant signing sessions
+- Digital certificate signatures (P12/PKCS12, JKS, SERVER, USER_CERT, PEM/UPLOAD)
+- Visual wet signature overlays (drawn, typed, or uploaded) — multiple per participant
+- Token-based participant access (no authentication required for participants)
+- Authenticated participant access for registered users via sign-requests API
+- Progress tracking for session owners
+- Optional signature summary page appended to finalized PDF
+- Automatic role downgrade after signing (security)
+- GDPR-compliant wet signature metadata cleanup
+
+## Architecture
+
+### Database Schema
+
+#### Core Tables
+
+**`workflow_sessions`**
+- Tracks signing sessions created by document owners
+- Links to original and processed (signed) PDF files
+- Stores session metadata (message, due date, status)
+
+**`workflow_participants`**
+- One record per participant per session
+- Tracks participant status: PENDING → VIEWED → SIGNED/DECLINED
+  - `NOTIFIED` status is reserved for a future email notification feature; no current code path sets it
+- Stores participant-specific metadata (certificates, wet signatures) as JSONB
+- Each participant holds their own `shareToken` (UUID) for token-based access — no separate `FileShare` record is created
+- `accessRole` controls what actions the participant can perform. `COMMENTER` (and `EDITOR`) allow submitting a signature; `VIEWER` does not. After signing/declining, effective role is automatically downgraded to `VIEWER`
+
+**`user_server_certificates`**
+- Stores auto-generated certificates per user
+- Enables "Use My Personal Certificate" option
+
+#### Extended Tables
+
+**`stored_files`**
+- Added `workflow_session_id` to link files to signing sessions
+- Added `file_purpose` enum (SIGNING_ORIGINAL, SIGNING_SIGNED, etc.)
+
+**`file_shares`**
+- Regular file shares are created when the session owner shares the document with other users via the file manager
+- The `workflow_participant_id` column is deprecated; participant access is self-contained in `WorkflowParticipant.shareToken`
+
+### Backend Architecture
+
+#### Service Layer
+
+**WorkflowSessionService** (`816 lines`)
+- Core workflow management service
+- Creates sessions with participants
+- Handles participant status updates
+- Stores signature metadata (certificates and wet signatures)
+- Finalizes sessions by coordinating signing process
+
+Key responsibilities:
+- Session lifecycle management (create, list, get details, delete)
+- Participant management (add, remove, notify)
+- Certificate submission storage
+- Wet signature metadata storage
+- Session finalization orchestration
+
+**UnifiedAccessControlService**
+- Validates participant tokens
+- Checks session status and expiration
+- Maps participant status to effective access role
+- Automatic role downgrade after signing: SIGNED/DECLINED → VIEWER role
+
+**UserServerCertificateService**
+- Auto-generates personal certificates for users
+- Manages certificate storage and retrieval
+- Enables "Use My Personal Certificate" signing option
+
+#### Controller Layer
+
+**SigningSessionController** (Owner-facing + Authenticated participant endpoints)
+- `POST /api/v1/security/cert-sign/sessions` - Create signing session
+- `GET /api/v1/security/cert-sign/sessions` - List user's sessions
+- `GET /api/v1/security/cert-sign/sessions/{id}` - Get session details
+- `GET /api/v1/security/cert-sign/sessions/{id}/pdf` - Download original PDF
+- `POST /api/v1/security/cert-sign/sessions/{id}/finalize` - Finalize and apply signatures
+- `GET /api/v1/security/cert-sign/sessions/{id}/signed-pdf` - Download signed PDF
+- `DELETE /api/v1/security/cert-sign/sessions/{id}` - Delete session
+- `POST /api/v1/security/cert-sign/sessions/{id}/participants` - Add participants
+- `DELETE /api/v1/security/cert-sign/sessions/{id}/participants/{participantId}` - Remove participant
+- `GET /api/v1/security/cert-sign/sign-requests` - List sign requests for authenticated user
+- `GET /api/v1/security/cert-sign/sign-requests/{id}` - Get sign request details
+- `GET /api/v1/security/cert-sign/sign-requests/{id}/document` - Download document for signing
+- `POST /api/v1/security/cert-sign/sign-requests/{id}/sign` - Sign document (authenticated)
+- `POST /api/v1/security/cert-sign/sign-requests/{id}/decline` - Decline sign request (authenticated)
+
+**WorkflowParticipantController** (Participant-facing, token-based)
+- `GET /api/v1/workflow/participant/session?token={token}` - View session details
+- `GET /api/v1/workflow/participant/details?token={token}` - Get participant details
+- `GET /api/v1/workflow/participant/document?token={token}` - Download PDF
+- `POST /api/v1/workflow/participant/submit-signature` - Submit signature
+- `POST /api/v1/workflow/participant/decline?token={token}` - Decline to sign
+
+#### Data Flow
+
+```
+Owner creates session → Participants receive tokens →
+Participants access via token (or authenticated) → Participants submit signatures →
+Owner finalizes → System applies signatures → [Optional: append summary page] → Signed PDF generated
+```
+
+### Frontend Architecture
+
+#### Quick Access Integration
+
+**SignPopout Component**
+- Displays in Quick Access Bar (top navigation)
+- Shows active and completed signing sessions
+- Auto-refreshes every 15 seconds to show signature progress
+- Badge indicator shows count of pending sessions
+
+**ActiveSessionsPanel**
+- Lists sessions where user is owner or participant

+## Signing Workflow Process
+
+### 1. Session Creation (Owner)
+
+```
+Owner → Uploads PDF → Selects participants → Creates session
+        ↓
+System creates:
+  - WorkflowSession record
+  - WorkflowParticipant records (one per participant, each with a unique shareToken)
+        ↓
+Participants receive token (via email or share link)
+```
+
+**API Call:**
+```bash
+POST /api/v1/security/cert-sign/sessions
+Content-Type: multipart/form-data
+
+file: document.pdf
+workflowType: SIGNING
+documentName: "contract.pdf"           # Optional display name
+participantUserIds: [1, 2, 3]          # Registered user IDs
+participantEmails: ["a@b.com"]         # External/unregistered users
+participants: [...]                    # Detailed participant configs (optional)
+message: "Please sign this contract"
+dueDate: "2025-12-31"
+ownerEmail: "owner@example.com"        # Optional, for notifications
+workflowMetadata: '{"showSignature": false, "showLogo": false, "includeSummaryPage": true}'
+```
+
+**Session-level `workflowMetadata` fields:**
+| Field | Type | Description |
+|-------|------|-------------|
+| `showSignature` | boolean | Show visible digital signature block on PDF |
+| `pageNumber` | integer | Page to place digital signature on |
+| `showLogo` | boolean | Show logo in digital signature block |
+| `includeSummaryPage` | boolean | Append a signature summary page before digital signing |
+
+**Response:**
+```json
+{
+  "sessionId": "uuid",
+  "documentName": "contract.pdf",
+  "participants": [
+    {
+      "userId": 1,
+      "email": "user1@example.com",
+      "shareToken": "token1",
+      "status": "PENDING"
+    }
+  ],
+  "participantCount": 3,
+  "signedCount": 0
+}
+```
+
+### 2. Participant Access
+
+```
+Participant → Clicks token link → Views session details
+        ↓
+Status changes: PENDING/NOTIFIED → VIEWED
+        ↓
+Participant downloads PDF to review
+```
+
+**Access URL (unauthenticated):**
+```
+https://app.example.com/sign?token={participant_token}
+```
+
+**Authenticated participants** can also use:
+```
+GET /api/v1/security/cert-sign/sign-requests
+GET /api/v1/security/cert-sign/sign-requests/{sessionId}
+GET /api/v1/security/cert-sign/sign-requests/{sessionId}/document
+```
+
+**Automatic Status Update:**
+- First access: PENDING/NOTIFIED → VIEWED
+- Downloads tracked but don't change status
+
+### 3. Signature Submission
+
+```
+Participant → Selects certificate type → Uploads certificate (if needed)
+           → Draws/uploads wet signatures (optional, multiple supported)
+           → Submits signature
+        ↓
+System stores:
+  - Certificate data (P12/JKS keystore as base64)
+  - Certificate password
+  - Wet signatures metadata (JSON array: base64 image + coordinates per signature)
+        ↓
+Status changes: VIEWED → SIGNED
+Access role: EDITOR → VIEWER (automatic downgrade)
+```
+
+**API Call (token-based, unauthenticated):**
+```bash
+POST /api/v1/workflow/participant/submit-signature
+Content-Type: multipart/form-data
+
+participantToken: {token}
+certType: P12 | JKS | SERVER | USER_CERT
+p12File: certificate.p12 (if certType=P12)
+jksFile: keystore.jks (if certType=JKS)
+password: cert_password
+showSignature: false
+pageNumber: 1
+location: "New York"
+reason: "I approve this contract"
+showLogo: false
+wetSignaturesData: '[{"page":0,"x":100,"y":200,"width":150,"height":50,"type":"IMAGE","data":"base64..."}]'
+```
+
+**API Call (authenticated users):**
+```bash
+POST /api/v1/security/cert-sign/sign-requests/{sessionId}/sign
+Content-Type: multipart/form-data
+
+certType: SERVER | USER_CERT | UPLOAD | PEM | PKCS12 | PFX | JKS
+p12File: certificate.p12 (if applicable)
+password: cert_password
+reason: "I approve this contract"
+location: "New York"
+wetSignaturesData: '[...]'
+```
+
+**Metadata Storage (JSONB):**
+```json
+{
+  "certificateSubmission": {
+    "certType": "P12",
+    "password": "cert_password",
+    "p12Keystore": "base64_encoded_keystore",
+    "showSignature": false,
+    "pageNumber": 1,
+    "location": "New York",
+    "reason": "I approve this contract",
+    "showLogo": false
+  },
+  "wetSignatures": [
+    {
+      "type": "IMAGE",
+      "data": "base64_image",
+      "page": 0,
+      "x": 100,
+      "y": 200,
+      "width": 150,
+      "height": 50
+    }
+  ]
+}
+```
+
+Note: Multiple wet signatures are supported per participant (array).
+
+### 4. Progress Tracking (Owner)
+
+```
+Owner → Views session list → Sees "2/5 signatures"
+      → Clicks session → Views participant status
+        ↓
+Participant list shows:
+  - user1@example.com: SIGNED ✓
+  - user2@example.com: SIGNED ✓
+  - user3@example.com: VIEWED (pending)
+  - user4@example.com: PENDING
+  - user5@example.com: DECLINED ✗
+        ↓
+Auto-refresh every 15 seconds
+```
+
+**Badge Colors:**
+- 🔵 Blue: 0/5 signatures (awaiting)
+- 🟡 Yellow: 2/5 signatures (partial)
+- 🟢 Green: 5/5 signatures (ready to finalize)
+
+### 5. Session Finalization
+
+```
+Owner → Clicks "Finalize" → System processes signatures
+        ↓
+Processing steps:
+  1. Apply wet signatures to PDF (visual overlays)
+  1.5. Append signature summary page (if includeSummaryPage=true)
+  2. Apply digital certificates in participant order
+     - Visual signature block suppressed when summary page is enabled
+  3. Store signed PDF
+  4. Clear wet signature metadata (GDPR compliance)
+        ↓
+Owner downloads signed PDF
+```
+
+**Finalization Process:**
+
+1. **Apply Wet Signatures First**
+   ```java
+   for (WetSignature sig : wetSignatures) {
+     PDPage page = document.getPage(sig.getPage());
+     byte[] imageBytes = Base64.decode(sig.getData());
+     // Convert Y from top-left (UI) to bottom-left (PDF) coordinate system
+     float pdfY = page.getMediaBox().getHeight() - sig.getY() - sig.getHeight();
+     PDImageXObject image = PDImageXObject.createFromByteArray(document, imageBytes, "signature");
+     contentStream.drawImage(image, sig.getX(), pdfY, sig.getWidth(), sig.getHeight());
+   }
+   ```
+
+2. **Append Summary Page (optional, before digital signing)**
+
+   If `includeSummaryPage=true`, a new A4 page is appended showing:
+   - Stirling logo and "Signature Summary" title
+   - Document name and session owner
+   - Finalization timestamp
+   - Per-participant: name, email, status, signed timestamp, reason, location, certificate type
+   - Supports overflow to additional pages
+
+   This step occurs **before** digital certificate signing so signatures are not invalidated.
+   When a summary page is added, the visual digital signature block (`showSignature`) is suppressed — wet signatures (hand-drawn overlays) are unaffected.
+
+3. **Apply Digital Certificates (in participant order)**
+   ```java
+   for (Participant p : participants) {
+     if (p.status == SIGNED) {
+       KeyStore keystore = buildKeystore(p.certificate);
+       // Reason: participant override > owner default > "Document Signing"
+       // Location: participant-provided only (no default)
+       CertSignController.sign(pdfBytes, keystore, password, settings);
+     }
+   }
+   ```
+
+4. **Store and Cleanup**
+   ```java
+   StoredFile signedFile = storeFile(signedPdfBytes, SIGNING_SIGNED);
+   session.setProcessedFile(signedFile);
+   session.setFinalized(true);
+
+   // GDPR: Clear sensitive metadata after finalization
+   for (Participant p : participants) {
+     p.metadata.remove("wetSignatures");         // Clears wet signature image data
+     p.metadata.remove("certificateSubmission"); // Clears keystore bytes + password
+   }
+   ```
+
+**API Call:**
+```bash
+POST /api/v1/security/cert-sign/sessions/{sessionId}/finalize
+Authorization: Bearer {owner_token}
+```
+
+**Response:** Binary PDF file with Content-Disposition header
+
+## Key Technical Features
+
+### 1. Double JSON Encoding Fix (Recent)
+
+**Problem:** JSONB columns were storing JSON strings instead of JSON objects, requiring double-parsing.
+
+**Solution:** Created `JsonMapConverter` JPA AttributeConverter:
+```java
+@Convert(converter = JsonMapConverter.class)
+@Column(name = "participant_metadata", columnDefinition = "jsonb")
+private Map<String, Object> participantMetadata;
+```
+
+**Benefits:**
+- Single parse on read
+- Proper JSON storage in PostgreSQL
+- Type-safe Map access
+- Backward compatible with legacy data
+
+### 2. Signature Progress Display (Recent)
+
+**Implementation:**
+- `WorkflowSessionResponse` includes `participantCount` and `signedCount`
+- `WorkflowMapper` calculates counts when converting to DTO
+- Frontend displays "X/Y signatures" in session list
+- Auto-refresh every 15 seconds keeps counts updated
+
+### 3. Token-Based Security
+
+**No Authentication Required for Participants:**
+- Participants access via secure token (UUID)
+- Token linked to specific participant and session
+- Automatic expiration support
+- One-time signing (cannot sign twice)
+
+**Authenticated Participant Access:**
+- Registered users can also access sign requests via `/api/v1/security/cert-sign/sign-requests`
+- Standard Spring Security authentication required
+- Supports additional cert types: UPLOAD, PEM, PKCS12, PFX
+
+**Automatic Role Downgrade:**
+- After signing: EDITOR → VIEWER
+- After declining: EDITOR → VIEWER
+- Prevents modification after action taken
+
+### 4. Storage Integration
+
+**Unified with File Sharing:**
+- All PDFs stored via `StorageProvider` (Database or Local)
+- Respects storage quotas
+- Supports files up to 100GB+ (with Local storage)
+- Consistent with existing file sharing infrastructure
+
+### 5. Certificate Types
+
+**P12/PKCS12/PFX:** User uploads PKCS#12 file + password
+**JKS:** User uploads Java KeyStore + password
+**PEM/UPLOAD:** User uploads PEM certificate + private key
+**SERVER:** Uses organization's server certificate (no upload needed)
+**USER_CERT:** Uses user's auto-generated personal certificate (one-click)
+
+Note: UPLOAD, PEM, PKCS12, PFX are available on the authenticated (`sign-requests`) path. The token-based path uses P12, JKS, SERVER, USER_CERT.

+## Security Considerations
+
+### Data Protection
+- Wet signature image data cleared after finalization (GDPR compliance)
+- Certificate submission data (keystore bytes + password) cleared after finalization (GDPR compliance)
+- Certificate passwords are not encrypted at rest while stored (TODO: encrypt at rest)
+- Token expiration support
+
+### Access Control
+- Owner authentication required for session management
+- Participant access via secure UUID tokens (no auth) or standard auth (sign-requests)
+- Automatic role downgrade prevents re-signing
+- Session status checks prevent unauthorized actions
+
+### Audit Trail
+- All participant actions tracked
+- FileShare access logged
+- Status transitions recorded
+- Notification history maintained
+
+## Performance Characteristics
+
+### Scalability
+- Supports PDFs up to 100GB+ (with Local storage provider)
+- Memory-efficient streaming for large files
+- IndexedDB caching on frontend
+- Database indexes on session_id, share_token, workflow_session_id
+
+### Response Times
+- Session creation: ~500ms (10MB file)
+- Session listing: ~100ms
+- Token validation: ~50ms
+- Finalization: ~2s per MB of PDF (varies by certificate operations)
+
+## Future Enhancements
+
+### Planned Features
+- Email notifications for participants
+- Reminder system for pending signatures
+- Bulk signing operations
+- Template-based signing workflows
+- Signature validation/verification UI
+- Certificate password encryption at rest
+- Certificate keystore cleanup after finalization (GDPR)
+- Webhook support for external integrations
+- Analytics dashboard for signing metrics
+
+### Additional Workflow Types
+- **REVIEW** - Document review with comments
+- **APPROVAL** - Multi-level approval chains
+- **COLLABORATION** - Real-time collaborative editing
+
+## Troubleshooting
+
+### Common Issues
+
+**"Token invalid" error:**
+- Check token exists in workflow_participants table
+- Verify session is not finalized
+- Check expiration date (expires_at)
+
+**Signature not appearing on PDF:**
+- Verify certificate type is correct
+- Check certificate password
+- Review logs for signing errors
+- Ensure PDFDocumentFactory is available
+
+**"Awaiting signatures" not updating:**
+- Backend should return participantCount and signedCount
+- Frontend auto-refresh every 15 seconds
+- Check network tab for API errors
+
+**Wet signatures not visible after finalization:**
+- Wet signatures are applied first as image overlays (Step 1)
+- Check `wetSignaturesData` was sent as valid JSON array
+- Verify page index is within document bounds
+- Note: wet signatures survive regardless of `includeSummaryPage` setting
+
+### Debug Queries
+
+```sql
+-- Check session status
+SELECT session_id, status, finalized,
+       (SELECT COUNT(*) FROM workflow_participants WHERE workflow_session_id = ws.id) as participant_count,
+       (SELECT COUNT(*) FROM workflow_participants WHERE workflow_session_id = ws.id AND status = 'SIGNED') as signed_count
+FROM workflow_sessions ws;
+
+-- Check participant tokens
+SELECT email, status, share_token, expires_at
+FROM workflow_participants
+WHERE workflow_session_id = (SELECT id FROM workflow_sessions WHERE session_id = '{session_id}');
+
+-- Check metadata storage
+SELECT email,
+       participant_metadata->'certificateSubmission'->>'certType' as cert_type,
+       jsonb_array_length(participant_metadata->'wetSignatures') as wet_sig_count
+FROM workflow_participants;
+```
+
+## Summary
+
+The Shared Signing feature provides a complete collaborative signing workflow with:
+- ✅ Multi-participant support with progress tracking
