DR-250. The user's diagnosis, and a better fix than modelling the handoff more carefully: a close that stops only what we believe is playing is fragile by construction. A close that stops everything is correct whatever the bookkeeping thinks. Two places it did not. The teardown's stop was gated on `didStartNativePlayback && !didStopBackendEarly` — flags describing what *this component* started. A background-audio handoff swaps the renderer underneath them, so after one they describe a player that is no longer making sound and the stop was skipped entirely. The audio stream kept running and the mini player adopted it, which is exactly why a movie reappeared as an audio track. It is unconditional now; `playerStop` is idempotent, so the cost of calling it when nothing plays is a no-op round trip, against the alternative of silently leaving audio running. And `PlayerController::stop` never cleared the handoff. Leaving the base offset and the active flag behind lets a later position read be interpreted against a handoff that no longer exists. Stopping now clears both. `didStartNativePlayback` had no remaining reader and is deleted rather than silenced — dead bookkeeping about which renderer was in charge is precisely the frontend playback state this contract is meant to remove, and the eslint ratchet caught it going one over. The underlying unconfirmed state swap is still there and still worth fixing — it is written up in media-player-controller.md. This makes the symptom impossible while that lands. 789 Rust tests, 1088 frontend, lint back at 158, clippy clean both ways.

JellyTau
A cross-platform Jellyfin client built with Tauri, SvelteKit, and TypeScript.
Business logic lives in a Rust backend; a UI-rich Svelte frontend handles presentation and talks to it over Tauri's IPC. Targets Linux (libmpv) and Android (ExoPlayer).
Getting Started
This project uses bun as its package manager.
# Activate the Rust environment (fish shell)
source "$HOME/.cargo/env.fish"
# Install dependencies
bun install
# Run in development
bun run tauri dev
# Type-check the frontend
bun run check
# Build for Linux
bun run tauri build
# Build for Android
bun run tauri android build
For the full set of build, test, and Android helper scripts, see scripts/README.md.

Contributing
CONTRIBUTING.md covers the setup, the gates a change has to pass, and the two rules that catch people out (bug fixes start with a failing test; Jellyfin's taxonomy stays in Rust). Please also read the Code of Conduct.

Verifying a download
Every release publishes SHA256SUMS covering all of its artifacts, plus an SBOM
of what went into the build:
sha256sum -c SHA256SUMS
Desktop builds update themselves from Settings → Updates, verifying each payload against JellyTau's signing key before installing. Android installs are handled by the system installer, so the app links to the releases page instead.
Recommended IDE Setup
VS Code + Svelte + Tauri + rust-analyzer.
