feat(sender): add envelope delete popup and client call

Updated SF-74-PLAN.md to document completed phases (6a–6e), including theme selection, dark mode, grid persistence, and logo placement. Highlighted pending tasks for phase 6f and clarified open questions.

Revised MIGRATION_PLAN.md with deep analysis findings and detailed steps for migrating `EnvelopeGenerator.Service_legacy` to a modern C# Worker Service. Addressed connection string handling, Quartz version mismatch, and TempFiles architecture.

Removed outdated markdown files from EnvelopeGenerator.sln and updated the solution structure for consistency.

Fixed incorrect "Read and confirmed" label in Signature Certificate reports for "Read and Sign" envelopes. Added branching logic in `ReportItem.vb` and updated resource files.

Resolved signature field formatting issues in finalized PDFs based on WISAG feedback. Added truncation logic in `PDFBurner.vb` and updated `PDFBurnerParams.vb` with per-field character limits.

+# EnvelopeGenerator - Agent Guide
+
+## Must Read First
+- **`COPILOT_CONTEXT.md`** - Architecture, coordinate systems, migration status
+- **`FORM_APPLICATION_CONTEXT.md`** - Legacy VB.NET features to migrate
+
+---
+
+## Documentation Catalog
+
+This section explains every markdown file in the repo: what it contains, why it exists, and when you need it. Read this before deciding which file to open.
+
+### Core Architecture Docs (Active — Always Relevant)
+
+#### `AGENTS.md` ← you are here
+**What:** Authoritative agent/copilot onboarding guide. Covers project structure, route table, render mode rules, coordinate system, API gaps, and common mistakes.
+**Why it exists:** Single source of truth for agents so they don't re-derive architecture from code on every session.
+**When you need it:** Always. Read first on every session.
+**Maintenance:** Update whenever project structure, routes, render modes, or naming conventions change.
+
+#### `COPILOT_CONTEXT.md`
+**What:** Deep-dive architecture reference. Covers the full Blazor Auto hybrid setup, authentication flows (JWT + cookies, per-envelope receiver tokens), service registration patterns, coordinate system proof, and an explicit "prefer Server/Server.Client over old WebUI/ReceiverUI" rule.
+**Why it exists:** Prevents agents from re-deriving or misinterpreting the hybrid SSR+WASM architecture. Also documents coordinate system evidence to prevent regressions (inches vs. points vs. pixels).
+**When you need it:**
+- Implementing any new page or service
+- Debugging auth/cookie issues
+- Any coordinate conversion question
+- Unsure which project a new file should go in
+**Maintenance:** Update when render mode assignments change, new auth schemes are added, or the coordinate system is touched.
+
+#### `FORM_APPLICATION_CONTEXT.md`
+**What:** Comprehensive reverse-engineering of the legacy VB.NET WinForms app (`EnvelopeGenerator.Form`). Documents every form (frmMain, frmEnvelopeEditor, frmFieldEditor, etc.), their UI layout, toolbar actions, data models, coordinate system, and a feature-by-feature migration mapping table to `EnvelopeGenerator.Server`.
+**Why it exists:** The WinForms app is the functional specification for the sender-side web UI. It documents the full intended workflow that is being migrated to Blazor — especially the envelope creation, signature field placement, and dashboard features that are not yet implemented.
+**When you need it:**
+- Implementing any sender-side feature (`/sender`, `/sender/editor`, `/sender/envelope/{id}`)
+- Understanding what a specific toolbar button or form should do
+- Designing API endpoints for sender workflow
+- Checking coordinate system behavior (INCHES proof is here)
+**Maintenance:** Update the mapping table as features are implemented (change `❌ Not implemented` → `✅ Exists`). Do not rename `ReceiverUI` back — it was the old project name; current target is `EnvelopeGenerator.Server`.
+
+#### `RECEIVER_PDF_VIEWER_CONTEXT.md`
+**What:** Detailed technical reference for the receiver-side PDF viewer (`EnvelopeReceiverPage.razor`). Documents the PDF.js integration, signature button rendering, JS interop API (`window.pdfViewer`), signature capture flow, HiDPI/zoom/thumbnail config, and the full component lifecycle.
+**Why it exists:** The receiver PDF viewer is the most complex component in the codebase. This doc prevents agents from misunderstanding the JS↔Blazor boundary, re-implementing already-solved problems (HiDPI, zoom, signature caching), or breaking the signing flow.
+**When you need it:**
+- Working on `EnvelopeReceiverPage.razor` or `pdf-viewer.js`
+- Adding new signature field rendering logic
+- Debugging signature rendering, zoom, or thumbnail issues
+- Implementing sender-side PDF.js overlay (signature field placement) — the receiver side is the reference implementation
+**Maintenance:** Update when `pdf-viewer.js` API changes, new JS interop functions are added, or the signing flow is modified.
+
+---
+
+### Deployment Docs
+
+#### `EnvelopeGenerator.Server/EnvelopeGenerator.Server/README.md`
+**What:** IIS publish and deployment guide for `EnvelopeGenerator.Server`. Covers why self-contained publish is required (WASM assembly version strictness), the exact `dotnet publish` command, IIS Application Pool settings (`No Managed Code`), directory structure after publish, and common deployment errors.
+**Why it exists:** Blazor Auto (Server + WASM hybrid) has non-obvious deployment requirements that differ from a standard ASP.NET Core app. Forgetting self-contained publish or using the wrong app pool will break WASM loading in production.
+**When you need it:**
+- Deploying to IIS for the first time
+- Troubleshooting 500 errors on production after deploy
+- Setting up a new deployment environment
+**Maintenance:** Update if the publish target, IIS config, or runtime version changes.
+
+---
+
+## Active Architecture (Post-Migration)
+
+**Frontend:** Blazor Auto (Server+WASM hybrid)
+- **EnvelopeGenerator.Server** (Server): `@rendermode InteractiveServer` - PDF viewers requiring DevExpress backend
+- **EnvelopeGenerator.Server.Client** (WASM): `@rendermode InteractiveWebAssembly` - Login, dashboards, business logic
+
+**Backend:** EnvelopeGenerator.API (ASP.NET Core 8.0)
+
+**Proxy:** YARP in EnvelopeGenerator.Server routes `/api/*` → `localhost:8088` (API)
+
+### Deprecated Projects - DO NOT USE
+- `EnvelopeGenerator.ReceiverUI` - Pure WASM (migrated to Server)
+- `EnvelopeGenerator.Web` - Razor Pages (replaced by Server)
+- **VB.NET projects** (`Form`, `Service`, `BBTests`) - Legacy, read-only for reference
+
+## Development Commands
+
+### Run Both Projects (Required)
+```powershell
+# Terminal 1 - API Backend
+cd EnvelopeGenerator.API
+dotnet run
+
+# Terminal 2 - Blazor Frontend
+cd EnvelopeGenerator.Server\EnvelopeGenerator.Server
+dotnet run
+```
+
+**Critical:** Both must run simultaneously. EnvelopeGenerator.Server proxy forwards `/api/*` to API.
+
+### Build
+```powershell
+dotnet build EnvelopeGenerator.sln
+```
+
+## Project Boundaries
+
+```
+EnvelopeGenerator.Domain/          # Entities (Envelope, Receiver, Document, etc.)
+EnvelopeGenerator.Application/     # MediatR CQRS (Commands, Queries, Handlers)
+EnvelopeGenerator.Infrastructure/  # EF Core, SQL executors, repositories
+EnvelopeGenerator.API/             # Controllers, endpoints

+    ├─ Models/                     # DTOs
+```
+
+## Route Structure (Critical)
+
+| Route | File Location | Render Mode | Purpose |
+|-------|--------------|-------------|---------|
+| `/` | `Server.Client/Pages/Index.razor` | WASM | Landing page |
+| `/sender/login` | `Server.Client/Pages/LoginSenderPage.razor` | WASM | Sender auth |
+| `/sender` | `Server/Components/Pages/EnvelopeSenderPage.razor` | **Server** | Sender dashboard |
+| `/sender/editor` | `Server/Components/Pages/EnvelopeSenderEditorPage.razor` | **Server** | Envelope editor + PDF viewer |
+| `/envelope/login/{key}` | `Server.Client/Pages/LoginReceiverPage.razor` | WASM | Receiver auth |
+| `/envelope/{key}` | `Server/Components/Pages/EnvelopeReceiverPage.razor` | **Server** | PDF viewer + signing |
+
+**Rule:** PDF viewers MUST use `@rendermode InteractiveServer` (DevExpress backend requirement). Everything else uses WASM.
+
+## Coordinate System (CRITICAL)
+
+**Database stores INCHES** (GdPicture14 native). Origin: top-left, Y-axis down.
+
+### Conversions
+```csharp
+// Database (INCHES) → PDF Points
+float points = inches * 72;
+
+// Database (INCHES) → DevExpress DX
+float dx = inches * 100;
+
+// PDF.js Pixels → Database (INCHES)
+float inches = (pixelX / canvasWidth) * pageWidthInches;
+```
+
+**A4 Page:** 8.27" wide × 11.69" tall = 595pt × 842pt
+
+**Signature Field Size:** 1.77" × 1.96" (FIXED, do not change)
+
+**Evidence:** See `COPILOT_CONTEXT.md` lines 158-185, `EnvelopeGenerator.Form/frmFieldEditor.vb`
+
+## API Architecture Quirks
+
+### Monolithic Endpoint (Avoid for UI)
+`POST /api/EnvelopeReceiver` - Creates envelope+document+receivers+fields atomically.
+- **Use case:** External API consumers
+- **Not suitable for:** Step-by-step UI workflow (no draft support, no partial updates)
+
+### Missing Granular Endpoints (Need to Create)
+```
+POST /api/Envelope/draft          # Create draft envelope
+PUT /api/Envelope/{id}            # Update metadata
+DELETE /api/Envelope/{id}         # Delete with reason
+POST /api/Envelope/{id}/document  # Upload PDF
+POST /api/Envelope/{id}/receivers # Add receiver
+POST /api/Envelope/{id}/signature-fields  # Place signature field
+POST /api/Envelope/{id}/send      # Send to receivers
+```
+
+See `FORM_APPLICATION_CONTEXT.md` for detailed workflow requirements.
+
+## Status Color Coding
+
+Form app uses DevExpress `CustomDrawCell`. EnvelopeGenerator.Server needs CSS:
+
+```css
+.envelope-row.status-partly-signed { background-color: #81C784; } /* GREEN_300 */
+.envelope-row.status-queued,
+.envelope-row.status-sent { background-color: #FFB74D; } /* ORANGE_300 */
+.envelope-row.status-completed { background-color: #81C784; }
+.envelope-row.status-deleted,
+.envelope-row.status-rejected { background-color: #E57373; } /* RED_300 */
+```
+
+## Configuration
+
+### YARP Proxy (`EnvelopeGenerator.Server/yarp.json`)
+Routes `/api/*`, `/swagger/*`, `/openapi/*`, `/scalar/*` → `https://localhost:8088`
+
+### PDF.js Settings (`EnvelopeGenerator.Server/wwwroot/appsettings.json`)
+```json
+{
+  "PdfViewerOptions": {
+    "ThumbnailBaseScale": 0.75,
+    "ThumbnailEnableHiDPI": true,
+    "MainCanvasEnableHiDPI": true,
+    "ZoomStepPercentage": 5
+  }
+}
+```
+
+### API Config (`API/appsettings.json`)
+- `ConnectionStrings:Default` - SQL Server DB
+- `AllowedOrigins` - CORS (includes `http://localhost:5131`, `http://localhost:7192`)
+- `Cache:SignatureCacheExpiration` - Signature persistence timeout
+- `PSPDFKitLicenseKey` - **DEPRECATED** (use PDF.js instead)
+
+## Migration Status
+
+### Complete ✅
+- Receiver login/authentication
+- PDF viewing with PDF.js (HiDPI, zoom, thumbnails)
+- Signature capture (draw/type/image)
+- Signature caching (Redis/SQL)
+- Sender login
+
+### Missing (High Priority) ❌
+- Sender dashboard (`/sender`) - Empty stub
+- Envelope editor (`/sender/envelope/{id}`)
+- Signature field placement tool (PDF.js + draggable overlays)
+- Granular API endpoints (draft, receivers, fields)
+- Master-detail grids for receivers/history
+
+## Common Mistakes (DO NOT REPEAT)
+
+| Mistake | Why Wrong |
+|---------|-----------|
+| Using iText7 in receiver pages | GPL license issue. Use PDF.js overlays. |
+| Using PSPDFKit | Removed from architecture. Use PDF.js + DevExpress. |
+| `@rendermode InteractiveWebAssembly` on PDF viewers | DevExpress DxPdfViewer requires server-side rendering. |
+| Hardcoded quality in PDF.js | Use `appsettings.json` `PdfViewerOptions`. |
+| Coordinates in points/pixels for DB | Database uses INCHES. Convert before save. |
+| `BottomMarginBand` for signatures | Repeats on every page. Use `DetailBand`. |
+
+## Testing
+
+**No automated tests exist yet.**
+
+Manual testing workflow:
+1. Start API (`dotnet run` in `EnvelopeGenerator.API`)
+2. Start EnvelopeGenerator.Server (`dotnet run` in `EnvelopeGenerator.Server\EnvelopeGenerator.Server`)
+3. Navigate to `https://localhost:5131` (or check console output for port)
+4. Test sender login at `/sender/login`
+5. Test receiver flow at `/envelope/login/{envelopeKey}`
+
+## Database
+
+**SQL Server** (DD_ECM)
+- Connection string in `API/appsettings.json`
+- EF Core migrations NOT used (manual SQL scripts)
+- Stored procedures: `PRSIG_*` prefix
+
+**Key Tables:**
+- `TBSIG_ENVELOPE` - Envelope metadata
+- `TBSIG_ENVELOPE_RECEIVER` - Receiver assignments
+- `TBSIG_DOC_RECEIVER_ELEMENT` - Signature fields (X, Y in INCHES)
+- `TBSIG_RECEIVER` - Receiver registry
+- `TBSIG_DOCUMENT` - PDF binary data
+- `TBSIG_ENVELOPE_HISTORY` - Audit trail
+
+## DevExpress
+
+**License:** Commercial (v25.2.3)
+**Components Used:**
+- `DxGrid` - Master-detail grids
+- `DxPdfViewer` - Server-side PDF rendering
+- `DxPopup` - Modal dialogs
+- `DxToolbar` - Action bars
+- `DxFormLayout` - Forms
+
+**Theme:** Blazing Berry (default)
+
+## JavaScript Interop
+
+**PDF Viewer:** `wwwroot/js/pdf-viewer.js`
+```javascript
+window.pdfViewer = {
+    initialize(canvasId, pdfDataUrl, dotNetRef),
+    renderPage(num),
+    renderSignatureButtons(signatures, pageNum, dotNetRef),
+    applySignature(signatureId, dataUrl, fullName, position, place),
+    zoomIn(), zoomOut(), dispose()
+}
+```
+
+**Signature Pad:** `wwwroot/js/receiver-signature.js`
+```javascript
+window.receiverSignature = {
+    initializeDrawPad(canvasId, dotNetRef),
+    getSignatureDataUrl(canvasId),
+    clearPad(canvasId)
+}
+```
+
+## Multi-Envelope Support
+
+Receivers can login to **multiple envelopes simultaneously** via per-envelope cookies:
+```
+AuthTokenSignFLOWReceiver.{envelopeKey}
+```
+
+Each envelope maintains independent authentication state.
+
+## External Dependencies

-# EnvelopeGenerator — AI Context Reference
+# EnvelopeGenerator — Current Workspace Context
 
 ## Purpose
-Digital document signing system with **unified Blazor WASM frontend** for both Senders and Receivers. Senders create envelopes and place signature fields. Receivers view PDFs, sign documents, export stamped PDFs.
+Digital document signing system for senders and receivers.
 
-**Primary Libraries:** DevExpress + PDF.js (PSPDFKit removed)
+- Senders authenticate, view envelope lists, and manage envelope workflows.
+- Receivers authenticate per envelope, open PDFs, create signatures, and apply them in the viewer.
+- The active UI stack is `Blazor Auto` with server-side and WebAssembly render modes.
+- Primary UI/PDF libraries are `DevExpress` and `PDF.js`.
 
 ---
 
-## Deployment Architecture
+## Active Application Structure
 
-**Two Presentation Projects (Both Required):**
+### Main Host
+**Primary active application:** `EnvelopeGenerator.Server`
 
-1. **EnvelopeGenerator.API** (ASP.NET Core Web API)
+`EnvelopeGenerator.Server` is the current runtime host and contains:
-   - Runs independently (development & production)
+- Blazor server host
-   - **YARP Reverse Proxy** configured via `yarp.json`
+- WebAssembly host integration
-   - Proxies requests to:
+- API controllers
-     - `EnvelopeGenerator.ReceiverUI` (Blazor WASM)
+- authentication/authorization setup
-     - External Auth.API service
+- Swagger/Scalar setup
-   - Serves as single entry point for all requests
+- YARP reverse proxy configuration
+- DevExpress server-side services
+- SQL Server distributed cache setup
 
-2. **EnvelopeGenerator.ReceiverUI** (Blazor WebAssembly)
+### Client Project
-   - Runs on separate host/port
+**Client UI project:** `EnvelopeGenerator.Server.Client`
-   - Accessed **only through API proxy** (not directly)
-   - Serves static files (HTML, JS, CSS, WASM)
 
-**Request Flow:**
+This project contains:
-```
+- WebAssembly-rendered pages
-Client ? API:8088 (YARP Proxy) ? ReceiverUI:52936 (Blazor WASM)
+- client-side services
-                                ? Auth.API:9090 (External Auth Service)
+- client models and options
-```
+- sender and receiver login flows
 
-**Configuration:** `EnvelopeGenerator.API/yarp.json`
+### Other Projects
+- `EnvelopeGenerator.Application` — MediatR/CQRS handlers and business logic
+- `EnvelopeGenerator.Domain` — domain models, constants, shared abstractions
+- `EnvelopeGenerator.Infrastructure` — EF Core and infrastructure services
+- `EnvelopeGenerator.PdfEditor` — PDF-related backend utilities
+- `EnvelopeGenerator.API` — still exists in the solution, but the current merged app host is `EnvelopeGenerator.Server`
+
+### Legacy / Do Not Touch
+- `EnvelopeGenerator.Service`
+- `EnvelopeGenerator.Form`
+- `EnvelopeGenerator.BBTests`
+- `EnvelopeGenerator.CommonServices`
 
 ---
 
-## ReceiverUI Route Structure
+## Current Hosting Model
 
-### Root Route
+`EnvelopeGenerator.Server/Program.cs` currently configures:
-| Route | File | Purpose |
+- `AddRazorComponents()` with both interactive server and interactive WebAssembly components
-|---|---|---|
+- `AddControllers()` and `MapControllers()`
-| `/` | `Index.razor` | Application entry point (landing page). | 
+- JWT authentication for sender and receiver flows
+- cookie authentication
+- authorization policies using `AuthScheme.Sender`, `AuthScheme.Receiver`, `AuthPolicy.Sender`, `AuthPolicy.Receiver`
+- `AddReverseProxy()` with `yarp.json`
+- Swagger / OpenAPI / Scalar
+- distributed SQL Server cache
+- DevExpress Blazor and DevExpress PDF Viewer server-side services
+- request localization middleware
 
-### Sender Routes
+This means the active app is a **merged UI + API host**.
-| Route | File | Purpose |
-|---|---|---|
-| `/sender/login` | `LoginSenderPage.razor` | Username/password authentication |
-| `/sender` | `EnvelopeSenderPage.razor` | Sender dashboard (envelope list) |
-
-### Receiver Routes
-| Route | File | Purpose |
-|---|---|---|
-| `/envelope/login/{EnvelopeKey}` | `LoginReceiverPage.razor` | Access code authentication for specific envelope |
-| `/envelope/{EnvelopeKey}` | `EnvelopeReceiverPage.razor` | View & sign envelope (PDF.js viewer) |
-
-**Multi-Envelope Support:** Receivers can login to multiple envelopes simultaneously (per-envelope cookie authentication).

-## Architecture Evolution
+## Reverse Proxy
 
-### Old Architecture (Deprecated)
+**Config file:** `EnvelopeGenerator.Server/EnvelopeGenerator.Server/yarp.json`
-- **Sender UI:** `EnvelopeGenerator.Web` (Razor Pages + PSPDFKit)
-- **Receiver UI:** `EnvelopeGenerator.ReceiverUI` (Blazor WASM + PDF.js)
-- **Backend:** `EnvelopeGenerator.API`
 
-### Current Architecture
+Current YARP usage is focused on **AuthHub forwarding**, not a general `/api/* -> EnvelopeGenerator.API` proxy.
-- **Unified Frontend:** `EnvelopeGenerator.ReceiverUI` (Blazor WASM) — **Both Senders & Receivers**
+
-- **Backend:** `EnvelopeGenerator.API` — **Both Senders & Receivers**
+Configured routes forward:
-- **Libraries:** DevExpress + PDF.js
+- `POST /api/auth` -> AuthHub `/api/auth/sign-flow`
-- **PSPDFKit:** **REMOVED**
+- `POST /api/Auth/envelope-receiver/{key}` -> AuthHub `/api/auth/envelope-receiver/{key}?cookie=true`

-## Localization & Culture Management
-
-**Current Architecture:** Blazor WebAssembly (client-side culture management)
-
-### Implementation Details
-
-**Culture Storage:**
-- Culture preference stored in browser's `localStorage` (key: `AppCulture`)
-- Managed by `CultureService.cs` (ReceiverUI/Services)
-- Supported cultures: `de-DE`, `en-US`, `fr-FR`
-
-**Culture Initialization:**
-- **Location:** `Program.cs` (lines 53-57)
-- Sets `CultureInfo.DefaultThreadCurrentCulture/UICulture` **before** app runs
-- **WASM-Safe:** Each user has isolated browser instance
-
-**Language Selector:**
-- **Component:** `LanguageSelector.razor` (ReceiverUI/Shared)
-- Displays flag icon + language name
-- Changes culture via `CultureService.SetCultureAsync()`
-- Navigates with `forceLoad: false` (smooth transition, no page reload)
-
-### ⚠️ MIGRATION WARNING: Blazor Server/Auto
-
-**Current approach is WASM-specific and will break in Server/Auto render modes!**
-
-**Why it breaks:**
-- `Program.cs:53-57` sets **global** `DefaultThreadCurrentCulture`
-- In Server/Auto, one app instance serves **all users**
-- User A selects German → User B sees German too (shared state)
-- Thread-safety issues and culture conflicts
-
-**Migration Checklist (when moving to Server/Auto):**
-
-1. **Remove global culture initialization** from `Program.cs` (lines 53-57)
-   - See detailed warning comment in the code
-
-2. **Add RequestLocalizationMiddleware** (Server-side approach):
-   ```csharp
-   app.UseRequestLocalization(options => {
-       options.SupportedCultures = new[] { "de-DE", "en-US", "fr-FR" };
-       options.SupportedUICultures = options.SupportedCultures;
-       options.RequestCultureProviders.Insert(0, new CookieRequestCultureProvider());
-   });
-   ```
-
-3. **OR** Use **per-circuit culture** (Blazor Server approach):
-   - Store culture in circuit-scoped service
-   - Use `CascadingParameter` to distribute to components
-   - See: https://learn.microsoft.com/aspnet/core/blazor/globalization-localization
-
-4. **Update `LanguageSelector.razor`:**
-   - Remove manual `CultureInfo.DefaultThreadCurrentCulture` assignment
-   - Use middleware/circuit culture provider instead
-
-5. **Update `CultureService.cs`:**
-   - Integrate with Server-side culture provider
-   - May need to store in cookies instead of localStorage
-
-**References:**
-- Microsoft Docs: [Blazor Globalization/Localization](https://learn.microsoft.com/aspnet/core/blazor/globalization-localization)
-- Current implementation: `Program.cs`, `CultureService.cs`, `LanguageSelector.razor`

-## EnvelopeReceiver — PDF.js Viewer & Signing
+## Current API Location
 
-**Route:** `/envelope/{EnvelopeKey}`  
+The active application exposes controllers from:
-**Tech:** PDF.js 3.11.174 + Blazor WASM + configurable quality  
+`EnvelopeGenerator.Server/EnvelopeGenerator.Server/Controllers`
-**File:** `ReceiverUI/Pages/EnvelopeReceiverPage.razor`
 
-### Key Features
+Current controller set includes:
-1. HiDPI/Retina support (4x quality)
+- `AnnotationController`
-2. Configurable quality (`appsettings.json`)
+- `AuthController`
-3. Unlimited zoom (50%-300%)
+- `CacheController`
-4. Ctrl+Wheel global zoom
+- `ConfigController`
-5. Resizable thumbnail sidebar (150-400px, localStorage)
+- `DocumentController`
-6. Responsive (desktop/mobile)
+- `EmailTemplateController`
+- `EnvelopeController`
+- `EnvelopeReceiverController`
+- `EnvelopeTypeController`
+- `HistoryController`
+- `LocalizationController`
+- `ReadOnlyController`
+- `ReceiverController`
+- `SignatureController`
+- `TfaRegistrationController`
 
-### Configuration
+Do not assume API behavior lives only in `EnvelopeGenerator.API`; the active merged host contains controller endpoints directly.
-**File:** `ReceiverUI/wwwroot/appsettings.json`
-
-```json
-{
-  "PdfViewer": {
-    "ThumbnailBaseScale": 0.75,
-    "ThumbnailEnableHiDPI": true,
-    "MainCanvasEnableHiDPI": true,
-    "ZoomStepPercentage": 5
-  }
-}
-```
-
-### JavaScript API
-**File:** `ReceiverUI/wwwroot/js/pdf-viewer.js`
-
-```javascript
-window.pdfViewer = {
-    initialize(canvasId, pdfDataUrl, dotNetRef),
-    renderPage(num),
-    renderSignatureButtons(signatures, pageNum, dotNetRef),
-    applySignature(signatureId, dataUrl, fullName, position, place),
-    zoomIn(), zoomOut(), dispose()
-}

-## Signature Workflow — EnvelopeReceiver
+## Authentication Model
 
-**IMPORTANT:** iText7 NOT used (GPL license issue). Client-side overlay system only.
+### Sender
+Client login page uses `EnvelopeGenerator.Server.Client/Services/AuthService.cs`.
 
-### Workflow Steps
+Key sender endpoints:
+- `POST /api/auth?cookie=true` — login
+- `GET /api/auth/check` — current sender access check
+- `POST /api/auth/logout` — logout
 
-1. **Page Load:**
+### Receiver
-   - Check `SignatureCacheService` for cached signature
+Receiver authentication is **per envelope**.
-   - If cached ? skip popup, load signature
-   - If not ? show automatic popup (mandatory)
 
-2. **Signature Popup (DxPopup):**
+Key receiver endpoints used by client services:
-   - **Cannot close** (no X, no ESC, no outside-click)
+- `POST /api/Auth/envelope-receiver/{envelopeKey}` — submit access code
-   - **3 Tabs:** Draw (canvas) / Text (font select) / Image (upload)
+- `GET /api/auth/check/envelope/{envelopeKey}` — check access
-   - **Required:** Full name, Place
+- `POST /api/auth/logout/envelope/{envelopeKey}` — logout receiver for one envelope
-   - **Optional:** Position
-   - **Save ?** Store in `_capturedSignature`, cache via API
 
-3. **Signature Buttons:**
+Receiver cookie resolution in server auth uses an envelope-specific cookie name derived from:
-   - Render purple "Unterschreiben" buttons at signature field positions
+- `AuthTokenSignFLOWReceiver.{envelopeKey}` pattern
-   - Coordinates: INCHES ? POINTS ? Pixels (scaled)
-   - File: `pdf-viewer.js` ? `renderSignatureButtons()`
 
-4. **Apply Signature (Click "Unterschreiben"):**
+### Receiver Server-Side Authorization
-   - JS: Remove button, create HTML overlay
+`EnvelopeReceiverPage.razor` does **not** rely on its own API access-check call for page authorization.
-   - Format: Image + separator + text (Name, Position, Place, Date)
-   - **NOT stamped on PDF bytes** (visual overlay only)
 
-5. **Re-rendering:**
+It uses:
-   - Zoom/Page change ? recalculate button positions
+- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Services/EnvelopeReceiverAuthorizationService.cs`
-   - Session state: `_capturedSignature` (lost on refresh)
 
-### Data Model
+Behavior:
-**File:** `ReceiverUI/Models/SignatureCaptureDto.cs`
+- tries the current `HttpContext.User`
+- if needed, reads the per-envelope receiver cookie directly
+- validates the JWT with the receiver auth scheme
+- verifies the token subject matches the route envelope key
+
+---
+
+## Receiver Page Data Loading
+
+Main server-side page data service:
+- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Services/EnvelopeReceiverPageDataService.cs`
+
+This service loads directly via MediatR and distributed cache:
+- document bytes
+- receiver envelope data
+- signature placeholders
+- cached signature data
+
+For signature placeholders, the service:
+- reads document receiver elements
+- filters them for the authenticated receiver
+- converts coordinates to `UnitOfLength.Point` before UI use
+
+---
+
+## Receiver PDF Viewer
+
+**Main file:** `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Components/Pages/EnvelopeReceiverPage.razor`
+
+Current receiver viewer characteristics:
+- route: `/envelope/{EnvelopeKey}`
+- render mode: `InteractiveServer`
+- PDF rendering: `PDF.js`
+- toolbar: page navigation, zoom, thumbnail toggle, signature navigation, signature reset
+- signature popup: `DxPopup`
+- thumbnail sidebar: resizable and stored in `localStorage`
+
+### JS Assets
+- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/wwwroot/js/pdf-viewer.js`
+- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/wwwroot/js/receiver-signature.js`
+
+### CSS
+- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/wwwroot/css/envelope-viewer.css`
+
+### PDF.js CDN
+- `https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.11.174/pdf.min.js`
+- `https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.11.174/pdf_viewer.min.css`
+
+---
+
+## Signature Workflow
+
+Receiver signatures are handled as a **viewer overlay workflow**.
+
+### Current behavior
+1. Server-side authorization validates receiver access.
+2. The page loads document bytes, receiver data, signature placeholders, and cached signature state.
+3. If no cached signature exists, the signature popup opens automatically.
+4. Receiver creates signature using one of three tabs:
+   - draw
+   - text
+   - image
+5. Required metadata:
+   - full name
+   - place
+6. Optional metadata:
+   - position
+7. Clicking a signature placeholder applies the signature as a client-side overlay in the PDF viewer.
+
+### Important note
+Although `itext` is referenced by the server project, the current receiver page signing flow is **not PDF stamping-based**. The active receiver UI uses client-side overlay behavior in the viewer.
+
+### Signature DTO
+`EnvelopeGenerator.Server.Client/Models/SignatureCaptureDto.cs`
 
 ```csharp
 public sealed record SignatureCaptureDto {
-    public required string DataUrl { get; init; }    // base64 PNG
+    public required string DataUrl { get; init; }
     public required string FullName { get; init; }
-    public string Position { get; init; } = "";      // Optional
+    public string Position { get; init; } = "";
     public required string Place { get; init; }
 }
 ```
 
 ---
 
-## Signature Caching
+## Signature Cache
 
-**Purpose:** Persist signature across page refreshes (distributed cache: Redis/SQL)
+### Active cache model
+The current receiver page cache flow is handled directly in the server project through:
+- `EnvelopeReceiverPageDataService`
+- `IDistributedCache`
+- SQL Server distributed cache configuration from `Program.cs`
 
-### API Endpoints
+### Cache key format
-**Controller:** `API/Controllers/CacheController.cs`
+Current server-side key prefix:
+- `envelope-generator.receiver-ui.signature:{receiverSignature}`
 
-- `POST /api/Cache/SignatureCapture/{envelopeKey}` — Save
+This is different from an envelope-key-only cache convention.
-- `GET /api/Cache/SignatureCapture/{envelopeKey}` — Load
-- `DELETE /api/Cache/SignatureCapture/{envelopeKey}` — Delete
 
-**Cache Key Format:**
+### Config
-```
+`EnvelopeGenerator.Server/EnvelopeGenerator.Server/Options/CacheOptions.cs`
-signature:91751687-8ae6-4777-bf5f-b8846085e62e:{envelopeKey}
+- section name: `Cache`
-```
+- option: `SignatureCacheExpiration`
 
-**Configuration:** `appsettings.json`
+### Related controller
-```json
+A cache API controller also exists in:
-{
+- `EnvelopeGenerator.Server/EnvelopeGenerator.Server/Controllers/CacheController.cs`
-  "Cache": {
-    "SignatureCacheExpiration": null  // or "02:00:00" for 2h
-  }
-}
-```
-
-### Service
-**File:** `ReceiverUI/Services/SignatureCacheService.cs`
-
-```csharp
-public class SignatureCacheService {
-    Task SaveSignatureAsync(string envelopeKey, SignatureCaptureDto signature);
-    Task<SignatureCaptureDto?> GetSignatureAsync(string envelopeKey);
-    Task DeleteSignatureAsync(string envelopeKey);
-}
-```
-
-**Error Handling:** Fire-and-forget saves, graceful degradation on load failure.

-## Sender Login
+## Sender Dashboard
 
-**Route:** `/sender/login`  
+**Main file:** `EnvelopeGenerator.Server/EnvelopeGenerator.Server.Client/Pages/EnvelopeSenderPage.razor`
-**File:** `ReceiverUI/Pages/LoginSenderPage.razor`  
-**Tech:** Bootstrap 5 + DevExpress Blazing Berry theme
 
-### AuthService Extension
+Current behavior:
-**File:** `ReceiverUI/Services/AuthService.cs`
+- checks sender access through `AuthService.CheckSenderAccessAsync()`
+- redirects to `/sender/login` when unauthorized
+- loads envelope list through client `EnvelopeService`
+- separates envelopes into active/completed tabs
+- uses `DevExpress DxGrid`
 
-```csharp
+The sender page is active, but create/edit/delete actions are still marked with TODO behavior in the UI page.
-public enum SenderLoginResult { Success, InvalidCredentials, Error }
-
-public async Task<SenderLoginResult> LoginSenderAsync(string username, string password) {
-    var response = await http.PostAsJsonAsync(
-        $"{_api.BaseUrl}/api/auth?cookie=true",
-        new { username, password });
-    
-    return response.StatusCode switch {
-        HttpStatusCode.OK => SenderLoginResult.Success,
-        HttpStatusCode.Unauthorized => SenderLoginResult.InvalidCredentials,
-        _ => SenderLoginResult.Error
-    };
-}
-```
-
-### API Integration
-**Endpoint:** `POST /api/auth?cookie=true`
-
-**Request:**
-```json
-{ "username": "TekH", "password": "***" }
-```
-
-**Response:**
-- `200 OK` ? Cookie set, redirect to `/sender`
-- `401 Unauthorized` ? Show error: "Ungültige Anmeldedaten"
-- Other ? Show error: "Serverfehler"
-
-**Cookie:** HTTP-only, Secure (HTTPS), SameSite=Strict
-
-### UI Flow
-1. User enters username + password
-2. Click "Anmelden" or press Enter
-3. Call `AuthService.LoginSenderAsync()`
-4. Success ? `Navigation.NavigateTo("/sender", forceLoad: true)`
-5. Error ? Display alert
 
 ---
 
-## Receiver Login
+## Localization
 
-**Route:** `/envelope/login/{EnvelopeKey}`  
+Current server host localization setup in `Program.cs`:
-**File:** `ReceiverUI/Pages/LoginReceiverPage.razor`
+- supported cultures: `de-DE`, `en-US`
+- request localization middleware is enabled
+- `QueryStringRequestCultureProvider` is added
+- cookie-based localization services are registered via `AddCookieBasedLocalizer()`
 
-**Multi-Envelope Support:** Cookies are stored per-envelope (e.g., `AuthTokenSignFLOWReceiver.{envelopeKey}`), allowing simultaneous authentication for multiple envelopes in the same browser session.
+Do not assume the old ReceiverUI-only `localStorage` culture approach is the current source of truth for the active host.
-
-### AuthService Method
-```csharp
-public enum EnvelopeLoginResult { Success, InvalidCode, NotFound, Error }
-
-public async Task<EnvelopeLoginResult> LoginEnvelopeReceiverAsync(string key, string accessCode) {
-    var form = new MultipartFormDataContent();
-    form.Add(new StringContent(accessCode), "AccessCode");
-    
-    var response = await http.PostAsync(
-        $"{_api.BaseUrl}/api/Auth/envelope-receiver/{Uri.EscapeDataString(key)}", form);
-    
-    return response.StatusCode switch {
-        HttpStatusCode.OK => EnvelopeLoginResult.Success,
-        HttpStatusCode.Unauthorized => EnvelopeLoginResult.InvalidCode,
-        HttpStatusCode.NotFound => EnvelopeLoginResult.NotFound,
-        _ => EnvelopeLoginResult.Error
-    };
-}
-```
-
-**Success:** Redirect to `/envelope/{key}`

-## Development Notes
+## Working Rules for This Workspace
 
-### Deprecated Projects
+- Treat `EnvelopeGenerator.Server` as the active main application host.
-**DO NOT USE:**
+- Treat `EnvelopeGenerator.Server.Client` as the active client UI project.
-- `EnvelopeGenerator.Web` (Razor Pages) — Replaced by unified ReceiverUI
+- Prefer current `Server` / `Server.Client` paths over old `WebUI` / `ReceiverUI` references.
-- PSPDFKit — Removed, use PDF.js + DevExpress instead
+- Do not use `EnvelopeGenerator.Web` or `EnvelopeGenerator.ReceiverUI` as the primary implementation target unless explicitly asked.
-
+- Do not modify the legacy VB.NET projects unless explicitly requested.
-### Legacy Projects (VB.NET)
+- For receiver PDF/signature work, prefer the current `PDF.js`-based flow in `EnvelopeReceiverPage.razor`.
-**DO NOT TOUCH:** `EnvelopeGenerator.Service`, `EnvelopeGenerator.Form`, `EnvelopeGenerator.BBTests`
+- For DevExpress PDF viewer issues, remember server-side services are registered in `EnvelopeGenerator.Server`.
-
-### Signature Coordinate Evidence
-**File:** `EnvelopeGenerator.Form/frmFieldEditor.vb` (VB.NET)
-
-```vb
-Private Const SIGNATURE_WIDTH As Single = 1.77   ' inches
-Private Const SIGNATURE_HEIGHT As Single = 1.96  ' inches
-
-Sub LoadAnnotation(pElement As Signature, ...)
-    oAnnotation.Left = CSng(pElement.X)    ' Direct INCHES assignment
-    oAnnotation.Top = CSng(pElement.Y)
-End Sub
-```
-
-Proves database uses INCHES natively.
 
 ---
 
-## Quick Reference
+**Last Updated:** 2026-06-29
-
-### When working with coordinates:
-1. **Database ? UI:** INCHES × 72 = PDF Points
-2. **UI ? Display:** Points × scale = Pixels
-3. **iText7 stamping:** Flip Y-axis (top-down ? bottom-up)
-
-### When adding features:
-1. Check `Mistakes History` first
-2. Prefer simplicity over complexity
-3. Use `appsettings.json` for configuration
-4. Keep consistent with existing design (Bootstrap 5 + Blazing Berry)
-5. **Unified frontend:** ReceiverUI serves both Senders and Receivers
-
-### When debugging:
-1. **Coordinates:** Always check unit system (inches/points/pixels)
-2. **Authentication:** Check cookie name/domain/SameSite
-3. **Cache:** Check Redis/SQL connection + key format
-4. **Frontend confusion:** Only use ReceiverUI (Web is deprecated)

-// - Option 2: Use CascadingParameter with per-circuit culture state
