LyAhn d30fe47876 perf(workers): strict priority pipeline across background workers
Workers now form a priority pipeline (thumbnails -> metadata ->
embeddings -> tagging): a worker only claims jobs when no
higher-priority tier has claimable work, so stages drain one at a time
at full speed instead of all workers contending for CPU (shared rayon
pool), disk, and the DB writer simultaneously.

Each tier gate is a single read-only EXISTS query per idle tick using
the same exclusion set the corresponding claim would (that worker''s
paused folders plus actively-indexing folders), so paused or mid-scan
work never blocks lower tiers, and failed jobs stop gating once they
leave pending. Deferred workers wake within one backoff interval
(250-750ms) of the higher tier draining.

A watcher-driven trickle of new files briefly pauses lower tiers by
design. A user-initiated tag run during a large embedding backlog
waits for it; pausing embeddings per folder overrides if tags are
wanted first.

Phokus

A local-first desktop media library for browsing, filtering, and curating image and video folders.

Features

  • Add and remove media folders; background indexing with live progress
  • Browse all media or filter by folder, type (image/video), favorites, or star rating
  • Filename search, semantic search (/s query), and tag search (/t tag)
  • Similar image search — find visually similar media by image or selected region
  • AI tagging via WD tagger (ONNX, CPU/DirectML) with confidence threshold control
  • Explore view — visual cluster map and tag cloud for browsing by theme
  • Duplicate finder — scan for exact duplicates by file hash with bulk delete
  • Lightbox preview with keyboard navigation, inline tag editing, and rating controls
  • Sort by date, name, size, rating, or duration
  • Grid density controls (compact / comfortable / detail)

Supported formats

Images Videos
jpg, jpeg, png, gif, bmp mp4, mov, m4v
tiff, tif, webp, avif, heic, heif webm

Stack

  • Tauri 2 + Rust backend
  • React 19 + TypeScript + Zustand
  • SQLite + sqlite-vec (vector search)
  • ONNX Runtime (ort) for AI tagging
  • Candle (Rust ML) for visual embeddings
  • FFmpeg sidecar for video thumbnails and metadata
  • Vite + Tailwind CSS v4

Development

Prerequisites: Node.js 20+, pnpm, Rust toolchain, Tauri system prerequisites for Windows.

pnpm install

# Run with hot-reload (frontend + Rust)
pnpm dev:app

# Frontend only
pnpm dev:vite

# Production build
pnpm build:app

How it works

  1. Add a folder from the sidebar — the Rust indexer walks it recursively.
  2. Supported files are written to SQLite with metadata (path, dimensions, media type, etc.).
  3. Background workers generate thumbnails, compute visual embeddings, and run AI tagging.
  4. Progress events stream back to the UI while the gallery updates incrementally.
  5. Embeddings power semantic search and the similar images feature via an HNSW index.
