J621 Roadmap / To-Dos

Working list of what's still missing, roughly in priority order. Check items off as they land.

1. Library management

• Duplicates engine
  • Exact MD5 duplicate detection with grouped results
  • Perceptual similarity (aHash, dHash, pHash, wHash) with threshold slider and algorithm toggles (imagehash server-side)
  • Visual similarity groups: pagination, selection, delete and dismiss
• Delete & storage page
  • Storage overview (watched folder, media folder, temp)
  • Delete by J-ID with preview grid and bulk selection (plus per-copy deletion of duplicate locations)
  • Temp folder cleanup
• Library search upgrades
  • Search by tags (custom + e621 tags) with a Filename / Tags / Both selector
  • Tag cloud in the sidebar (click to search, hidden from guests for blacklisted items)
  • Status filter (matched / custom / unknown — not_found/deleted arrive with the e621 match cache)

2. e621 integration

• Download progress bar on the detail view
  • Backend download task (status, progress %, downloaded/total bytes, speed)
  • Progress endpoint the SPA polls; cancel support
  • Frontend progress bar with speed and cancel on /detail/<post>
  • The status footer's "Active Workers" now counts running download tasks
• Download to client — streams the e621 original straight to the browser (works for guests; host-restricted proxy, no library write)
• Match local files to e621
  • Match by MD5 from the library detail, plus manual post ID linking (with an MD5-mismatch warning) and unlink
  • Batch cache status for the whole library (matched / not_found / deleted) via background scan tasks (/api/matches/) and manage.py match_e621
  • Show match status + e621 metadata in the library: status badge and match card on the detail, and not_found / deleted status filters
• IQDB reverse search
  • Search from a local file (POST /iqdb_queries.json)
  • Show candidate posts to link
• Follows
  • Follow tags/pools, Followed screens with unseen badges
  • "Followed" nav entry
• F shortcut to favorite a post, tag finder in the Ctrl+K palette

3. Uploads & ingestion pipeline

Files now stage first and are resolved before entering the library.

• Backend staging storage
  • TempUpload model: user, md5, filename, temp path, status (pending / visual_match / completed / error), resolution
  • Files land in a temp folder first; only completed uploads move into the watched library folder
  • Pending/upload list endpoint, file serving, discard endpoint
  • cleanup_temp_uploads command for old staged files
• Auto-upload / auto-match
  • MD5 computed on staging; exact duplicates resolve immediately
  • MD5 batch-checked against e621; matches auto-complete with post metadata stored and rating seeded
• IQDB similarity on upload (SPA-driven)
  • Automatic + manual IQDB checks with candidate posts
  • "Visual Similarity Detected" state with candidate picker
  • Perceptual-hash comparison against the library (staged uploads are flagged with their library matches as soon as they land)
• Upload UI
  • Three-column board: Pending & Unmatched / Visual Similarity Detected / Auto-uploaded & Indexed
  • Metadata modal (link to e621 post, IQDB candidates, custom metadata)
  • Per-file progress plus batch processing indicator

4. Staff tools

• Optimization modal (image quality, GIF/APNG resolution+FPS+compression, video bitrate/presets/two-pass/hw-accel) with original vs processed preview and override
• Stats dashboard
  • CPU / RAM / GPU / disk usage
  • Active jobs list (this is what makes the footer "Active Workers" real)
  • Live log tail

5. Shell & polish

• 18+ entry screen: an age check gates the app before anything renders (remembered per browser in localStorage)
• Toasts instead of inline messages / confirm dialogs
• Mobile drawer polish for metadata panels (design spec §layout)
• Profile pictures: staff Users page sets avatars from library J-IDs (self-service picker in Account still pending)
• Profile extras (per-user browse preferences)
• Command palette: tag finder, recent searches

6. Infrastructure

• Guest blacklist refresh on a timer (refresh_guest_blacklist via cron/systemd)
• Production setup: build the SPA, serve via Nginx (static + /media + /library), systemd unit for Waitress
• Automated tests (backend API + frontend components)
• Backfill e621 metadata for items downloaded before metadata was stored (re-download or a "match" action)

Dependencies / notes

• Duplicates and upload visual-similarity share the perceptual hashing layer (imagehash/imgdd server-side + a hash cache table).
• Download progress, optimization jobs and the stats "Active Workers" count all want the same background-task/progress primitive — design it once.
• IQDB and e621 matching depend on e621 credentials being configured; the SPA talks to e621 directly for browsing, while the backend e621 client (apps/library/e621.py) handles metadata matching and batch scans.
