Browser Tab Title ⚠️ MAJOR ARCHITECTURAL CHANGE +**Decision**: Option (b) - Create HTML wrapper page with embedded viewer + +**Impact**: +- Cannot serve files directly - must create wrapper HTML page +- Need to embed PDF viewer (using `` or `` tags) +- Need separate download endpoint for non-PDF files +- Can control page title, metadata display, and navigation +- More complex implementation than direct file serving + +**Implementation Notes**: +- Wrapper page at `/hearing-lists/{court-id}/{list-id}` renders HTML +- Embedded PDF viewer or download link based on file type +- Page title set in HTML: `[Court Name] – [List Name]` +- Separate API endpoint for raw file download: `/api/flat-file/{artefactId}/download` + +### 4. Language Toggle ✓ +**Decision**: Option (a) - Don't implement toggle - files are language-specific + +**Impact**: +- No language toggle implementation needed +- Files are inherently English or Welsh based on `language` field +- Error messages use i18n middleware (existing functionality) + +### 5. Azure Blob Storage Scope ✓ +**Decision**: Option (a) - Separate ticket for blob migration + +**Impact**: +- Keep filesystem storage for this ticket +- Document limitation in deployment notes +- Create follow-up ticket for production storage solution + +### 6. Metadata Display ✓ +**Decision**: Option (a) - Not implemented initially + +**Impact**: +- Wrapper page shows court name and list name (in title bar) +- No additional metadata display in page body +- Can be added in future enhancement if needed + +### 7. File Size Limits ✓ +**Decision**: No artificial limit + +**Impact**: +- Let browser handle large files +- User can download if browser struggles with inline display +- Monitor performance in production + +### 8. File Upload Format ✓ +**Decision**: Verify manual-upload stores as `{uuid}.{ext}` with extension in artefactId + +**Impact**: +- Need to verify existing manual-upload implementation +- Ensure consistency across upload flows +- Document expected format + +## Revised Implementation Approach + +### Major Changes from Original Specification + +1. **URL Routing**: + - Original: `/flat-file/[artefactId]` + - Revised: `/hearing-lists/:locationId/:artefactId` + - Requires validation that locationId matches artefact + +2. **File Serving**: + - Original: Direct file serving with Content-Disposition headers + - Revised: HTML wrapper page with embedded viewer + - Requires separate download API endpoint + +3. **Page Structure**: + - Original: Simple error page or direct file + - Revised: Full page with GOV.UK template, embedded viewer, metadata + +### New Components Required + +1. **HTML Wrapper Page**: + - Route: `/hearing-lists/:locationId/:artefactId` + - Template: `hearing-lists/view.njk` + - Controller: `hearing-lists/view.ts` + - Shows court name, list name, publication date + - Embeds PDF viewer or provides download link + +2. **Download API Endpoint**: + - Route: `/api/flat-file/:artefactId/download` + - Serves raw file with appropriate headers + - Used by embedded viewer and download buttons + +3. **PDF Embed Logic**: + - Use `` tag with fallback to download link + - Detect PDF support in browser + - Provide download button for all file types + +### Risks and Considerations + +1. **PDF Embed Browser Compatibility**: + - Safari, Chrome, Firefox have different PDF viewer behaviors + - Mobile browsers may not support embedded PDF viewing + - Need graceful fallback to download + +2. **URL Complexity**: + - locationId validation adds security concern + - More database queries per request + - Need clear error messages for invalid court-id/list-id combinations + +3. **Increased Scope**: + - HTML wrapper significantly increases implementation complexity + - More template work, more JavaScript potentially needed + - More E2E test scenarios + +### Updated Acceptance Criteria Mapping + +| Original AC | Implementation Strategy | +|-------------|------------------------| +| AC4: Open in new tab | `target="_blank"` on link in summary page | +| AC5: Display all cases | Embed full file in viewer or provide download | +| AC6: Preserve format | Use native browser PDF viewer or download | +| AC7: Scroll/zoom/download | Browser viewer controls + download button | +| AC8: Court/list in tab title | HTML wrapper with `` tag | +| AC9: Error messages | Error page for validation failures | +| AC10: GOV.UK compliance | Use GOV.UK template for wrapper page | + +## Next Steps + +1.

The decisions below represent the agreed implementation approach: + +### 1. File Extension Storage ✅ RESOLVED +**Decision**: Store as `{uuid}.{ext}` in artefactId field + +- Files stored as `c1baacc3-8280-43ae-8551-24080c0654f9.pdf` in filesystem +- artefactId in database includes extension: `c1baacc3-8280-43ae-8551-24080c0654f9.pdf` +- Extract extension using `artefactId.substring(artefactId.lastIndexOf("."))` +- No database schema changes required + +### 2. URL Pattern ✅ RESOLVED +**Decision**: Implement `/hearing-lists/:locationId/:artefactId` as specified in ticket + +- URL matches ticket specification: `/hearing-lists/{court-id}/{list-id}` +- locationId maps to court-id +- artefactId serves as list-id +- Requires validation that locationId matches artefact.locationId for security +- More complex than simple UUID lookup, but matches user expectations + +### 3. Browser Tab Title ✅ RESOLVED +**Decision**: Create HTML wrapper page with embedded viewer + +- HTML wrapper controls page title via `<title>` tag +- Displays "[Court Name] – [List Name]" in browser tab +- Embeds PDF viewer using `<object>` tag for PDF files +- Provides download links for non-PDF files +- More complex than direct file serving, but meets AC8 requirement + +### 4. Language Toggle ✅ RESOLVED +**Decision**: Don't implement toggle - files are language-specific + +- Files are inherently English or Welsh based on `language` field +- No toggle needed - user selects language version from summary page +- Error messages use existing i18n middleware + +### 5. Azure Blob Storage Scope ✅ RESOLVED +**Decision**: Separate ticket for production storage solution + +- Keep filesystem storage for this ticket +- Document storage limitation in deployment notes +- Create follow-up ticket for Azure Blob Storage implementation +- Focus this ticket on viewing functionality only + +### 6. Metadata Display ✅ RESOLVED +**Decision**: Display court name and list name in wrapper page + +- HTML wrapper shows court name and list name in page heading +- Browser tab title also shows this information +- No additional metadata in page body initially +- Can be enhanced in future if needed + +### 7. File Size Limits ✅ RESOLVED +**Decision**: No artificial limit + +- Let browser handle large files +- User can download if browser struggles with inline display +- Monitor performance in production and adjust if needed + +### 8. File Upload Format ✅ RESOLVED +**Decision**: Verify and ensure manual-upload stores as `{uuid}.{ext}` + +- Confirm existing manual-upload implementation stores with extension +- Ensure artefactId field includes extension +- Document expected format for consistency + +## Infrastructure Considerations + +### Current State + +The application currently uses filesystem storage for uploaded files: + +- **Storage Location**: `storage/temp/uploads/` (relative to `process.cwd()`) +- **File Naming**: `{uuid}.{extension}` (e.g., `c1baacc3-8280-43ae-8551-24080c0654f9.pdf`) +- **Implementation**: Node.js `fs` module for file operations +- **Current Files**: Manual-upload already uses this approach (see `libs/admin-pages/src/manual-upload/file-storage.ts`) + +### Development Environment + +No infrastructure changes required: + +- Local filesystem storage works correctly +- Files persist across development sessions +- Single-instance application + +### Production Deployment Considerations + +#### Critical Issue: Ephemeral Container Storage + +The current filesystem-based storage approach has significant limitations in containerized Kubernetes deployments: + +1. **Pod Ephemeral Storage** + - Container filesystems are ephemeral and wiped on pod restart + - Uploaded files will be lost when pods are recreated (deployments, scaling, crashes) + - Files stored in one pod are not accessible to other pods + +2. **Horizontal Scaling Impact** + - Multiple pod replicas each have isolated filesystems + - File upload may hit Pod A, but file retrieval request may hit Pod B (load balancing) + - Results in "file not found" errors despite successful upload + +3. **Current Helm Configuration** + -
