Richard R 88809b826b fix(compute): unify PDF layout result handling with object key support 
Update compute backend interfaces and job logic to consistently handle parsed
PDF layout results as either direct data or S3 object key references. Refactor
result types, local and worker backends, and job processing to support this
pattern. Improves flexibility for large document parsing and object storage
integration.

📄🔊 OpenReader

OpenReader is an open source, self-host-friendly text-to-speech document reader built with Next.js for EPUB, PDF, TXT, MD, and DOCX with synchronized read-along playback.

Previously named OpenReader-WebUI.

Get started in the docs.

✨ Highlights

  • 🧱 Layout-aware PDF parsing with PP-DocLayoutV3 (ONNX) — structured block detection, cross-page stitching, and geometry-based highlighting for precise read-along sync.
  • ⏱️ Word-by-word highlighting via built-in ONNX Whisper alignment — no external dependencies, runs in-process (COMPUTE_MODE=local) or offloaded to a scalable NATS JetStream-backed worker (COMPUTE_MODE=worker).
  • ⚡ Segment-based read-along for EPUB, PDF, TXT, MD, and DOCX — sentence-aware TTS with cached audio segments, background preloading, and resumable playback.
  • 🎯 Multi-provider TTS — self-hosted OpenAI-compatible servers (Kokoro-FastAPI, KittenTTS-FastAPI, Orpheus-FastAPI) or cloud APIs (OpenAI, Replicate, DeepInfra).
  • 🎧 Audiobook export in m4b/mp3 with resumable chapter processing.
  • 🗂️ Flexible backend — embedded SeaweedFS or S3-compatible storage, SQLite or Postgres, server library import, and device sync.
  • 🐳 Self-host friendly — Docker (amd64/arm64), optional auth, and automatic startup migrations.
