-# 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.

-## 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;
-```
-

-# 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

-## 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)

-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
- ✅ Multiple certificate types (P12/PKCS12/PFX, JKS, PEM, SERVER, USER_CERT)
- ✅ Visual wet signature overlays (multiple per participant)
- ✅ Token-based security for unauthenticated participants
- ✅ Authenticated participant access via sign-requests API
- ✅ Automatic role management
- ✅ Large file support (100GB+)
- ✅ GDPR-compliant wet signature metadata cleanup
- ✅ Real-time progress updates
- ✅ Full frontend integration with Quick Access Bar
- ✅ Optional signature summary page with logo and participant details
-
-The architecture leverages existing file sharing infrastructure while adding workflow-specific features, ensuring consistency and maintainability across the application.
