+## 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.
+
+---
+
+### Ticket / Feature Plans (Active Work Items)
+
+#### `EnvelopeGenerator.Server/SF-74-PLAN.md`
+**What:** Implementation plan for SF-74 ticket — Theme selection, Dark Mode, Grid Layout Persistence, signFLOW logo, and customer logo area on the sender dashboard. Includes the original ticket requirements, component breakdown, and implementation steps.
+**Why it exists:** Captures the agreed scope and implementation decisions for SF-74 so work can be resumed or reviewed without re-reading the ticket system.
+**When you need it:**
+- Resuming work on theme, dark mode, or grid persistence features
+- Checking what was agreed for logo positioning and size
+- Verifying which features of SF-74 are complete vs. pending
+**Maintenance:** Mark items as complete as they are implemented. Archive when the ticket is closed.
+
+---
+
+### 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.
+
+---
+
+### Fix Reports (Historical — Read-Only)
+
+These files document completed bug fixes. They exist as audit trails and as references if a similar issue resurfaces. Do not modify them.
+
+#### `fix-report-label-read-and-confirmed.md`
+**What:** Documents the fix for an incorrect label in the Signature Certificate report (`Signierungszertifikat`). For "Read and Sign" envelope type (`EnvelopeTypeId = 2`), the history event showed "Document signed" instead of "Read and confirmed" / "Gelesen und bestätigt".
+**Branch:** `fix/report-label-read-and-confirmed` — **COMPLETED**
+**When you need it:** If a similar report label regression appears, or when adding new envelope type-specific label logic to the certificate report.
+
+#### `fix-signature-field-formatting.md`
+**What:** Documents a signature stamp layout fix triggered by WISAG customer feedback (email 3/7/2026). The finalized PDF's signature stamp had incorrect spacing: certificate hash too close to name, position text wrapping, no spacing before date. Fix was applied in the GdPicture14 PDF burning pipeline — not in the Blazor UI.
+**When you need it:** If signature stamp formatting regresses, or when modifying the PDF stamping/burning pipeline in the API or infrastructure layer.
+
+---
+
+### Service Migration Docs
+
+#### `EnvelopeGenerator.Service/MIGRATION_PLAN.md`
+**What:** Migration plan (v3) for porting `EnvelopeGenerator.Service_legacy` (VB.NET Windows Service) to `EnvelopeGenerator.Service` (C# Worker Service, .NET Framework 4.6.2). Documents connection string handling, job scheduling (Quartz → IHostedService), and deep analysis of legacy code.
+**Why it exists:** The Windows Service handles background jobs (email dispatch, envelope finalization). This plan ensures the port is complete and no job logic is silently dropped.
+**When you need it:**
+- Modifying background jobs (email sending, PDF finalization, access code dispatch)
+- Debugging service startup or job execution issues
+- Checking if a specific legacy VB.NET job has been ported
+

-    Microsoft ResX Schema 
-    
-    Version 2.0
-    
-    The primary goals of this format is to allow a simple XML format 
-    that is mostly human readable. The generation and parsing of the 
-    various data types are done through the TypeConverter classes 
-    associated with the data types.
-    
-    Example:
-    
-    ... ado.net/XML headers & schema ...
-    <resheader name="resmimetype">text/microsoft-resx</resheader>
-    <resheader name="version">2.0</resheader>
-    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
-    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
-    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
-    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
-    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
-        <value>[base64 mime encoded serialized .NET Framework object]</value>
-    </data>
-    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
-        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
-        <comment>This is a comment</comment>
-    </data>
-                
-    There are any number of "resheader" rows that contain simple 
-    name/value pairs.
-    
-    Each data row contains a name, and value. The row also contains a 
-    type or mimetype. Type corresponds to a .NET class that support 
-    text/value conversion through the TypeConverter architecture. 
-    Classes that don't support this are serialized and stored with the 
-    mimetype set.
-    
-    The mimetype is used for serialized objects, and tells the 
-    ResXResourceReader how to depersist the object. This is currently not 
-    extensible. For a given mimetype the value must be set accordingly:
-    
-    Note - application/x-microsoft.net.object.binary.base64 is the format 
-    that the ResXResourceWriter will generate, however the reader can 
-    read any of the formats listed below.
-    
-    mimetype: application/x-microsoft.net.object.binary.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
-            : and then encoded with base64 encoding.
-    
-    mimetype: application/x-microsoft.net.object.soap.base64
-    value   : The object must be serialized with 
-            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
-            : and then encoded with base64 encoding.
-
-    mimetype: application/x-microsoft.net.object.bytearray.base64
-    value   : The object must be serialized into a byte array 
-            : using a System.ComponentModel.TypeConverter
-            : and then encoded with base64 encoding.

-// - Server runs a single shared instance for all users
-// - Setting global culture affects ALL connected users simultaneously
-// - Race conditions and culture conflicts will occur
-//
-// Migration Guide:
-// - Option 1: Use RequestLocalizationMiddleware for per-request culture
-// - Option 2: Use CascadingParameter with per-circuit culture state
-// - See: https://learn.microsoft.com/aspnet/core/blazor/globalization-localization

-// - LanguageSelector.razor (remove manual culture setting)

-[Open Iconic v1.1.1](https://github.com/iconic/open-iconic)
-===========
-
-### Open Iconic is the open source sibling of [Iconic](https://github.com/iconic/open-iconic). It is a hyper-legible collection of 223 icons with a tiny footprint—ready to use with Bootstrap and Foundation. [View the collection](https://github.com/iconic/open-iconic)
-
-
-
-## What's in Open Iconic?
-
-* 223 icons designed to be legible down to 8 pixels
-* Super-light SVG files - 61.8 for the entire set 
-* SVG sprite—the modern replacement for icon fonts
-* Webfont (EOT, OTF, SVG, TTF, WOFF), PNG and WebP formats
-* Webfont stylesheets (including versions for Bootstrap and Foundation) in CSS, LESS, SCSS and Stylus formats
-* PNG and WebP raster images in 8px, 16px, 24px, 32px, 48px and 64px.
-
-
-## Getting Started
-
-#### For code samples and everything else you need to get started with Open Iconic, check out our [Icons](https://github.com/iconic/open-iconic) and [Reference](https://github.com/iconic/open-iconic) sections.
-
-### General Usage
-
-#### Using Open Iconic's SVGs
-
-We like SVGs and we think they're the way to display icons on the web. Since Open Iconic are just basic SVGs, we suggest you display them like you would any other image (don't forget the `alt` attribute).
-
-```
-<img src="/open-iconic/svg/icon-name.svg" alt="icon name">
-```
-
-#### Using Open Iconic's SVG Sprite
-
-Open Iconic also comes in a SVG sprite which allows you to display all the icons in the set with a single request. It's like an icon font, without being a hack.
-
-Adding an icon from an SVG sprite is a little different than what you're used to, but it's still a piece of cake. *Tip: To make your icons easily style able, we suggest adding a general class to the* `<svg>` *tag and a unique class name for each different icon in the* `<use>` *tag.*  
-
-```
-<svg class="icon">
-  <use xlink:href="open-iconic.svg#account-login" class="icon-account-login"></use>
-</svg>
-```
-
-Sizing icons only needs basic CSS. All the icons are in a square format, so just set the `<svg>` tag with equal width and height dimensions.
-
-```
-.icon {
-  width: 16px;
-  height: 16px;
-}
-```
-
-Coloring icons is even easier. All you need to do is set the `fill` rule on the `<use>` tag.
-
-```
-.icon-account-login {
-  fill: #f00;
-}
-```
-
-To learn more about SVG Sprites, read [Chris Coyier's guide](http://css-tricks.com/svg-sprites-use-better-icon-fonts/).
-
-#### Using Open Iconic's Icon Font...
-
-
-##### …with Bootstrap
-
-You can find our Bootstrap stylesheets in `font/css/open-iconic-bootstrap.{css, less, scss, styl}`
-
-
-```
-<link href="/open-iconic/font/css/open-iconic-bootstrap.css" rel="stylesheet">
-```
-
-
-```
-<span class="oi oi-icon-name" title="icon name" aria-hidden="true"></span>
-```
-
-##### …with Foundation
-
-You can find our Foundation stylesheets in `font/css/open-iconic-foundation.{css, less, scss, styl}`
-
-```
-<link href="/open-iconic/font/css/open-iconic-foundation.css" rel="stylesheet">
-```
-
-
-```
-<span class="fi-icon-name" title="icon name" aria-hidden="true"></span>
-```
-
-##### …on its own
-
-You can find our default stylesheets in `font/css/open-iconic.{css, less, scss, styl}`
-
-```
-<link href="/open-iconic/font/css/open-iconic.css" rel="stylesheet">

-        <p>Als Anbieter von lokalen Lösungen (OnPremise) setzt der Hersteller des signFLOWs, die Digital Data GmbH,
-            einen klaren Schwerpunkt auf Datenschutz und Datensicherheit. Für Sie bedeutet dies, dass nur die nötigsten
-            Daten erhoben und gespeichert werden (Datensparsamkeit bzw. Datenminimierung). Außerdem kommen bei der

-        <h2>3. Datenerhebung</h2>
-        <h3>3.1 Die folgenden Kategorien personenbezogener Daten werden verarbeitet</h3>
-        <ul>
-            <li>Namen: Benutzername, Vor- und Zunamen sowie Ihre digitale Unterschrift</li>
-            <li>Kontaktdaten: Telefonnummer, Mobilfunknummer und E-Mail-Adresse</li>
-            <li>Technische Daten: IP-Adresse, Zeitpunkt des Zugriffs oder Zugriffsversuchs</li>
-        </ul>
-
-        <h3>3.2 Ursprung der personenbezogenen Daten</h3>
-        <p>Sie haben die unter 3.1 stehenden Daten vorab an Ihren Geschäftspartner (die verantwortliche Stelle)
-            übermittelt. Diese Übermittlung kann mündlich per Telefon, im persönlichen Kontakt, per E-Mail oder per
-            Kontaktformular geschehen sein.</p>
-        <p>Ihre digitale Signatur übermitteln Sie eigenständig, bei der Unterzeichnung eines Dokuments.</p>
-
-        <h3>3.3 Aufbewahrungsfristen / Speicherungsdauer</h3>
-        <ul>
-            <li>Die automatische E-Mail Korrespondenz wird für 6 Jahre aufbewahrt.</li>
-            <li>Unterzeichnete Verträge werden für die Dauer ihrer Laufzeit + 10 Jahre aufbewahrt.</li>
-            <li>Der technische Vorgang wird in der signFLOW Softwarelösung je nach Dokumentart bzw. Vertragsart
-                unbegrenzt aufbewahrt.</li>
-        </ul>
-        <p>Ihre personenbezogenen Daten werden aber grundsätzlich anonymisiert, wenn:</p>
-        <ul>
-            <li>Der Vertrag ausgelaufen ist und die gesetzliche Aufbewahrungszeit vorbei ist.</li>
-            <li>Der Vertrag von Ihnen abgelehnt wurde bzw. nie unterschrieben wurde.</li>
-        </ul>
-        <p>Die gesetzlichen Grundlagen dieser Aufbewahrungsfristen bieten unter anderen:</p>
-        <ul>
-            <li>Handelsgesetzbuch (HGB)</li>
-            <li>Abgabenordnung (AO)</li>
-            <li>Grundsätze zur ordnungsgemäßen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in
-                elektronischer Form sowie zum Datenzugriff (GoBD)</li>
-        </ul>
-        <p>
-            Abhängig von der spezifischen Dokumentart, kann die Aufbewahrungsfrist variieren. Außerdem können sich
-            Zeiten
-            verlängern, falls Unregelmäßigkeiten auftreten. Z.B.: eine rechtliche Auseinandersetzung droht oder aktuell
-            läuft.
-        </p>
-
-        <h3>3.4 Verarbeitungszweck</h3>
-        <p>Die unter 3.1 definierten personenbezogenen Daten werden verarbeitet um:</p>
-        <ul>
-            <li>Den technisch notwendigen Prozess abzubilden bzw. anbieten zu können.</li>
-            <li>Damit Sie als Endbenutzer in der Lage sind, ein zu unterzeichnendes Dokument, digital zu unterschreiben,
-                ist die Feststellung der Identität des Antragstellers, Antragsprüfung und -abwicklung, Abrechnung sowie
-                die Wahrung der Dokumentationspflichten notwendig.</li>
-        </ul>
-        <p>In Einzelfällen werden Daten zur Fehlerbehebung insbesondere bei Supportanfragen von der IT-Abteilung
-            gesondert behandelt oder ggf. an den Hersteller weitergegeben.</p>
-        <p>Im Zuge der Maßnahmen zur Sicherstellung der Informationssicherheit, insbesondere zur Identifizierung und
-            Abwehr von Angriffen, sowie zur Durchführung interner und externer Audits, der Exportkontrolle und der
-            Prüfung von Sanktionslisten, erfolgt ebenfalls eine Datenverarbeitung. Bei Anfragen gemäß §8 Abs. 2 VDG
-            werden die entsprechenden Informationen an die zuständigen Stellen übermittelt.</p>

-        <h3>3.5 Rechtmäßigkeit der Verarbeitung</h3>
-        <p>Ihre Daten werden auf Grundlage einer sich anbahnenden oder bereits vorhandenen Geschäftsbeziehung erhoben.
-        </p>
-        <p>Die rechtliche Grundlage für die Übermittlung an zuständige Stellen bildet §8 Abs. 2 VDG. Anfragen von
-            Betroffenen werden gemäß den Artikeln 12 bis 23 der DSGVO sowie den Paragraphen 32 bis 37 des BDSG
-            bearbeitet.</p>
-
-        <h3>3.6 Berechtigte Interessen</h3>
-        <p>Ein berechtigtes Interesse der verantwortlichen Stelle gemäß Art. 6 Abs. 1 lit. f DSGVO besteht in den
-            folgenden Fällen:</p>
-        <p>Es werden Maßnahmen zur Informationssicherheit ergriffen, die sowohl präventive technische als auch
-            organisatorische Maßnahmen sowie die Behandlung von Vorfällen umfassen. Ziel ist es, potenzielle Schäden für
-            das Unternehmen, die von der Datenverarbeitung betroffenen Personen und die Nutzer der Vertrauensdienste zu
-            bewerten und zu vermeiden.</p>
-
-        <h3>3.7 Erforderlichkeit der Daten</h3>
-        <p>Die erhobenen Daten stellen das Minimum der nötigen Daten zwecks digitaler Unterschrift dar. Ohne die unter
-            3.1 genannten Daten, kann der Dienst nicht betrieben werden.</p>
-        <p>Besonders wichtig ist die Angabe einer Mobilfunknummer oder einer deutschen Festnetznummer, da diese für die
-            Authentifizierung und die Signaturauslösung als zweiter Faktor verwendet wird. Ohne diesen
-            Sicherheitsmechanismus kann der Dienst leider nicht bereitgestellt werden.</p>
-
-        <h3>3.8 Weitergabe von Daten</h3>
-        <p>Eine systemische Übermittlung von Daten findet nicht statt.</p>
-        <p>Daten werden nur in Ausnahmefällen, zwecks Supportleistungen, an den Hersteller weitergegeben. Mit der
-            Hersteller besteht ein gültiger Auftragsdatenverarbeitungsvertrag (AVV), welcher die Sicherheit und
-            Integrität des Umgangs mit Ihren Daten gewährleistet.</p>

-        <h2>3. Data Collection</h2>
-        <h3>3.1 The following categories of personal data are processed</h3>
-        <ul>
-            <li>Names: Username, first and last names as well as your digital signature</li>
-            <li>Contact details: Phone number, mobile phone number, and email address</li>
-            <li>Technical data: IP address, time of access, or access attempts</li>
-        </ul>
-
-        <h3>3.2 Source of the personal data</h3>
-        <p>You have previously provided the data mentioned under 3.1 to your business partner (the responsible entity).
-            This transmission may have occurred verbally over the phone, in personal contact, via email, or via a
-            contact form.</p>
-        <p>You transmit your digital signature independently when signing a document.</p>
-
-        <h3>3.3 Retention periods / Storage duration</h3>
-        <ul>
-            <li>Automatic email correspondence is stored for 6 years.</li>
-            <li>Signed contracts are retained for the duration of their term + 10 years.</li>
-            <li>The technical process is stored in the signFLOW software solution indefinitely, depending on the
-                document or contract type.</li>
-        </ul>
-        <p>Your personal data will generally be anonymized when:</p>
-        <ul>
-            <li>The contract has expired, and the statutory retention period is over.</li>
-            <li>The contract was rejected by you or never signed.</li>
-        </ul>
-        <p>The legal basis for these retention periods includes:</p>
-        <ul>
-            <li>Commercial Code (HGB)</li>
-            <li>Tax Code (AO)</li>
-            <li>Principles for the Proper Keeping and Retention of Books, Records, and Documents in Electronic Form and
-                for Data Access (GoBD)</li>
-        </ul>
-        <p>
-            Depending on the specific type of document, the retention period may vary. Additionally, the periods may be
-            extended in case of irregularities, such as a pending or ongoing legal dispute.
-        </p>
-
-        <h3>3.4 Purpose of processing</h3>
-        <p>The personal data defined under 3.1 is processed to:</p>
-        <ul>
-            <li>Support or provide the technically necessary process.</li>
-            <li>Enable you, as the end user, to sign a document digitally. This requires the identification of the
-                applicant, application verification and processing, billing, and compliance with documentation
-                requirements.</li>
-        </ul>
-        <p>In individual cases, data is processed separately by the IT department, particularly in response to support
-            requests, or possibly forwarded to the manufacturer for further processing.</p>
-        <p>Data processing also occurs to ensure information security, especially for the identification and prevention
-            of attacks, and for conducting internal and external audits, export controls, and sanctions list checks.
-            Information may also be transmitted to the relevant authorities in accordance with Section 8 (2) VDG.</p>
-
-        <h3>3.5 Legality of processing</h3>
-        <p>Your data is collected based on an impending or already existing business relationship.</p>
-        <p>The legal basis for the transmission to competent authorities is Section 8 (2) VDG. Requests from data
-            subjects are processed in accordance with Articles 12 to 23 of the GDPR and Sections 32 to 37 of the Federal
-            Data Protection Act (BDSG).</p>
-
-        <h3>3.6 Legitimate interests</h3>
-        <p>A legitimate interest of the responsible entity in accordance with Article 6 (1) (f) GDPR exists in the
-            following cases:</p>
-        <p>Measures are taken for information security, which include both preventive technical and organizational
-            measures as well as incident handling. The aim is to assess and avoid potential harm to the company, the
-            individuals affected by data processing, and the users of trust services.</p>
-
-        <h3>3.7 Necessity of data</h3>
-        <p>The collected data represents the minimum necessary for the digital signature. Without the data mentioned
-            under 3.1, the service cannot be operated.</p>
-        <p>It is particularly important to provide a mobile number or a German landline number, as this is used for
-            authentication and signature triggering as a second factor. Without this security mechanism, the service
-            cannot be provided.</p>
-
-        <h3>3.8 Data transfer</h3>
-        <p>Systematic data transmission does not take place.</p>
-        <p>Data is only forwarded to the manufacturer for support services in exceptional cases. A valid data processing
-            agreement (DPA) exists with the manufacturer, which ensures the security and integrity of the handling of
-            your data.</p>

-
-        <h3>3.7 Nécessité des données</h3>
-        <p>Les données collectées représentent le minimum nécessaire pour la signature numérique. Sans les données mentionnées en 3.1, le service ne peut pas être opéré.</p>
