-## Unreleased
+## 1.14.0 — 2026-10-17
+
+### Changed
+- **The codebase is mypy-clean** and plain `uv run mypy` works (`[tool.mypy]`
+  in `pyproject.toml` lists the targets). Qt enums are now fully qualified
+  (`QDialog.DialogCode.Accepted`, `QMessageBox.StandardButton.Yes`,
+  `Qt.GlobalColor.red`, …) instead of PySide6's short aliases, and the few
+  loosely typed spots (tag schema, transforms, `on_files_changed`, dialog cell
+  widgets) are annotated. No behaviour change.
+
+### Removed
+- `src/core/media_utils.py` — Tagger-era leftovers (`load_icon` returned a
+  Tkinter image, `add_video_resolution_tag` logged via `print()`); nothing in
+  the app called either.
+
+### Dependencies
+- Removed `pillow` — `media_utils` was its only user.
+
+## 1.13.0 — 2026-10-12
 
 ### Changed
 - **The standalone build is now a single file.** `Curator.spec` produces one
   self-contained `dist/Curator` executable (onefile) instead of a
   `dist/Curator/` folder of libraries. It unpacks to a temp folder on every
   start, so launching takes a few seconds longer.
-
-### Dependencies
-- Added `pyinstaller` to the dev group — `uv run pyinstaller Curator.spec`
-  now works out of the box (it was used for builds but never declared).

   removed. Values already stored keep working in miniDLNA filename templates

 # Curator
 
-Curator is a desktop **movie-library manager (Filmotéka)**. You import video
-files into a managed **pool**, tag them, and Curator generates a browsable
-**Filmotéka** — a directory tree of hardlinks into the pool — without ever
-duplicating the actual video data on disk.
+Curator is a PySide6 desktop app for managing a **Jellyfin-first movie and series
+library**. You import video files into a managed **pool**; Curator identifies them
+through **TMDb**, names and lays them out the way Jellyfin expects, and can
+generate a genre-split **miniDLNA / Filmotéka** tree of hardlinks for dumb DLNA
+players — without ever duplicating the video data on disk.
 
-Curator is a fork of the former *Tagger* project; the tagging, filtering and
-hardlink-tree machinery is inherited and extended into a full library workflow.
+Metadata (posters, plots, `.nfo` files) is Jellyfin's job; Curator owns the files,
+their names and the library structure.
 
 ## Concepts
 
-- **Pool** — the managed repository of files and the **single source of truth**.
-  Curator owns it: it imports and removes files itself, so nothing moves behind
-  its back. The pool has two top-level folders:
-  - `Filmy` — movies, organized by tags into the generated tree.
-  - `Seriály` — series (and any other **copy-as-is** folder), mirrored verbatim.
-- **Filmotéka (output)** — a generated tree of **hardlinks** into the pool. It is
-  fully disposable: delete it and nothing is lost, because it is regenerated from
-  the pool on demand.
-- **Pool index** — all pool metadata lives in a single `.Curator.!index` JSON
-  file at the pool root (title, ČSFD link, tags, date per file).
+- **Pool** — the managed folder and the **single source of truth**. Curator
+  imports, renames and removes files itself, so nothing moves behind its back.
+  Each top-level folder is a **library** with a kind:
 
-## Workflow
+  | Kind | Holds | Layout |
+  |------|-------|--------|
+  | `movie` | movies | `Title (rok) [tmdbid].ext`, or a folder once a film has several versions |
+  | `series` | series | `Series (rok) [tmdbid]/Season NN/SxxEyy - Series.ext` |
+  | `mixed` | movies and series together | as above, side by side |
+  | `homevideo` | files without a TMDb id | mirrored as-is |
 
-1. Configure the **pool** and the **Filmotéka output** folder.
-2. **Import a movie**: pick a video, enter its **Title** and a **ČSFD link**. The
-   file is copied (non-destructively) into `pool/Filmy` as `Title.ext` and
-   recorded in the index. If a ČSFD link is given, Curator fetches the movie from
-   [ČSFD.cz](https://www.csfd.cz) and assigns **Žánr / Rok / Země původu** tags
-   automatically (use "Načíst tagy z ČSFD" to (re)fetch later).
-3. **Tag** movies (Rok, Žánr, Hodnocení, …) and filter them in the UI.
-4. **Generate the Filmotéka**: movies become a `Category/Tag/film` hardlink tree
-   (from the `Rok` / `Žánr` / `Hodnocení` categories); copy-as-is folders such as
-   `Seriály` are mirrored 1:1 as hardlinks.
+- **Pool index** — Curator's own metadata (TMDb id, ČSFD link, versions, tags,
+  library settings) lives in one `.Curator.!index` JSON file at the pool root.
+- **miniDLNA output** — a generated tree of **hardlinks** into the pool, built
+  from the genres/years/ratings in Jellyfin's NFO files. It is disposable: delete
+  it and regenerate it at any time.
+
+## Features
+
+- Import movies and episodes with a mandatory **TMDb id**; Czech titles come from
+  TMDb, with **ČSFD** as a fallback and as a bridge for finding the right TMDb id.
+- **Multiple versions** of one film (2D/3D, 4K, director's cut) and **multi-part**
+  films and episodes, named so Jellyfin groups them.
+- Subtitle sidecars follow their video through renames.
+- Duplicate check, video integrity check (FFmpeg), library statistics.
+- Jellyfin integration: trigger a library scan, read what Jellyfin has.
+- miniDLNA tree scoped per library, with "Tipy dne" and "Nově přidané" folders.
+
+## Requirements
+
+- [uv](https://docs.astral.sh/uv/) — manages Python 3.14 and all dependencies
+- `ffmpeg` / `ffprobe` on `PATH` — optional, for the integrity check
+
+## Configuration
+
+Secrets and settings are read from a `.env` file in the project root (never
+committed):
+
+| Variable | Purpose |
+|----------|---------|
+| `TMDB_API_KEY` | TMDb API key — required for identifying movies and series |
+| `TMDB_LANGUAGE` | TMDb language, default `cs-CZ` |
+| `JELLYFIN_URL` | Jellyfin server URL — optional, for the Jellyfin menu |
+| `JELLYFIN_API_KEY` | Jellyfin API key — optional |
+| `ENV_DEBUG` | `true` enables debug mode |
+
+The pool and output folders are chosen in the app (*Pool* menu).
