"TV" and "Shows" showed identical contents, and so would any two libraries of the same type. save_to_cache bound library_id NULL on every row it wrote, so nothing in the cache knew where an item came from. The only association available was the collection_type/item_type taxonomy, and that is unable in principle to tell two libraries of one type apart -- both are 'tvshows', so every Series on the server satisfies either. DR-277 narrowed the library clause, which stopped Books and Photos serving the whole server, but no clause over that taxonomy could have fixed this. The write path is the single choke point every cached row passes through and it already knows the parent being browsed, so it now resolves the owning library once per call: the parent itself when it is a library, otherwise the library its parent item was filed under, which carries the association down a hierarchy as it is browsed. Synthetic parents like "favorites" match neither and stay NULL -- they are not a library and span several. This is what makes the taxonomy stop being load-bearing. Library types nobody enumerated -- Books, Photos, Collections, mixed libraries with no collection type at all -- are now scoped by the same link as everything else rather than by whether someone remembered to add an arm for them. Existing rows cannot be repaired locally, because the association was never stored: migration 025 clears synced_at to force a re-fetch, the same move MIGRATION_018 made for is_folder. Nothing is deleted -- downloads, favourites and playback positions live in other tables, and a cleared synced_at only means "ask the server again". The new tests seed through save_to_cache rather than inserting rows directly, so they exercise the path that was actually broken.

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.
