Reported by @IndividualGhost1905: printing the same model ten times and
then deleting nine archive entries (to keep the file list tidy) silently
rewound the totals on the Statistics page — total prints, filament,
cost, and per-print energy all dropped back to whatever the surviving
row contributed, as if the other nine prints had never happened.
Root cause: every metric in get_archive_stats is recomputed live from
PrintArchive rows via COUNT / SUM, so removing a row removes its
contribution. Energy in the default "Total" mode already survived
deletion because it reads the smart-plug lifetime counters — that's
the architectural shape we now generalise to the rest.
Fix: soft delete with opt-in hard purge.
Backend:
- New nullable, indexed deleted_at column on print_archives, dialect-
conditional migration (DATETIME on SQLite, TIMESTAMP on PostgreSQL).
- ArchiveService.soft_delete_archive flips deleted_at and removes the
files from disk (still reclaims storage); the path-safety checks were
extracted into _resolve_archive_dir_for_delete so soft and hard delete
share the rules.
- DELETE /archives/{id} accepts ?purge_stats=true; default is soft.
- Listings filter deleted_at IS NULL: list_archives, search FTS + LIKE
fallback, GET /{id} (404 on soft-deleted), tag listing, duplicate
detection (so a 1-live + 9-soft-deleted group no longer marks the
survivor as a duplicate), and ArchiveComparisonService's "similar"
suggestions. GET /stats and GET /slim deliberately do NOT filter so
Quick Stats and the dashboard widgets keep counting deleted prints.
Frontend:
- ConfirmModal gained an optional children slot.
- ArchivesPage (both card and detail views) own a per-instance
deletePurgeStats boolean and render an opt-in checkbox in the delete
dialog; resets to off on every close so the destructive option is
never sticky.
- api.deleteArchive(id, purgeStats?) appends ?purge_stats=true only
when the box is ticked.
- One new i18n key archives.modal.deletePurgeStats added across all 8
locales (full German, English fallbacks elsewhere).
- New APIBrowser component with full OpenAPI schema integration
- Fetches and parses /openapi.json automatically
- Groups endpoints by API tags (printers, archives, settings, etc.)
- Expandable endpoint sections with color-coded method badges
- Path parameter, query parameter, and JSON body editors
- Auto-populates request body with schema examples
- Live API request execution with response display
- Response shows status code, timing, and formatted JSON
- Copy response button with clipboard fallback
- Search to filter endpoints across all categories
- Expand All / Collapse All buttons
- Link to Swagger UI (/docs)
- Two-column layout for API Keys tab
- Left: API key management + webhook documentation
- Right: API Browser with dedicated test key input
- Parameter validation
- Shows warning for missing required parameters
- Validates before sending requests to avoid 422 errors
- UX improvements
- "Use in API Browser" button on newly created keys
- Responsive layout (stacked on mobile, side-by-side on xl+)
### Projects / Print Grouping
- Create projects to group related prints (e.g., "Voron Build" with 50 parts)
- Track progress with target count and completion percentage
- Assign archives to projects via edit modal or context menu
- Project cards show archive thumbnails with clickable links
- Color-coded project badges on archive cards
- Filter and manage projects by status (active/completed/archived)
### Full-Text Search (FTS5)
- SQLite FTS5 virtual table for efficient searching
- Search across print_name, filename, tags, notes, designer, filament_type
- Automatic index sync with triggers for INSERT/UPDATE/DELETE
### Webhooks & API Keys
- API key authentication with granular permissions
- Permissions: can_read_status, can_manage_queue, can_control_printer
- Secure key generation with prefix display only after creation
- Settings page API Keys tab for key management
- Webhook endpoints for external integrations
### Failure Analysis
- Dashboard widget showing failure rate with color coding
- Correlate failures with conditions (filament type, printer, time)
- Top failure reasons breakdown
- Weekly trend visualization
### Archive Comparison
- Select 2-5 archives to compare side-by-side
- Highlight differences in print settings (yellow)
- Success/failure correlation insights
- Modal with close via button, X, Escape, or backdrop
### CSV/Excel Export
- Export archives and statistics with current filters
- Support for both CSV and Excel (.xlsx) formats
- openpyxl dependency added
## Bug Fixes
- Fixed context menu submenu not showing (removed overflow-hidden)
- Fixed project card thumbnails using correct API endpoint
- Fixed EditArchiveModal to invalidate projects query on save
- Fixed clipboard API fallback for HTTP contexts
- Fixed archive PATCH 500 error (FTS5 index rebuild)
- Fixed FastAPI trailing slash routing for projects endpoint
## UI Improvements
- Context menu submenu with hover/click support
- Project badge on archive cards with project color
- "Go to Project" context menu item for assigned archives
- Clickable project card thumbnails linking to archives
- Reset Layout button moved to Stats page header
