# PROJECT.md

This file is project-specific. Only include information directly related to the concrete project — goals, current state, architecture decisions, known issues, and tasks.

## Origin

Curator is a fork of the former **Tagger** project. The tagging, filtering and
hardlink-tree parts are inherited and keep working as before. On top of that,
Curator becomes a full **movie library manager (Filmotéka)**.

## Core idea

Curator manages a personal movie library based on two folders:

- **Pool** — the managed repository of video files. This is the **single source
  of truth**. Curator manages the pool itself (insert/remove file), so files are
  never moved by hand. The pool has exactly two top-level folders: **Filmy**
  (movies — tag-based tree) and **Seriály** (series — a "copy-as-is" folder
  mirrored 1:1 into the output; see Design decisions). Every file lives here
  exactly once.
- **Filmotéka (output)** — a generated, browsable directory tree made only of
  **hardlinks** into the pool (the same mechanism as today's hardlink manager).
  It is fully disposable: deleting the Filmotéka folder loses nothing, because
  it can always be regenerated from the pool.

### Workflow

1. The user configures two folders: the **pool** and the **Filmotéka output**.
2. The user picks a video file via "Open file".
3. Curator opens a dialog to fill in basic info — at minimum the **title/name**
   and a **ČSFD link**.
4. Curator **renames** the file and **moves** it into the managed pool, and
   writes a **metadata file** describing it.
5. From the pool, Curator **generates the Filmotéka** — a complex tree of
   hardlinks built from each file's tags/metadata (like the current hardlink
   manager, but driven by the pool).
6. Deleting the Filmotéka has no effect on the pool; the tree is regenerated on
   demand.

## Current state

- Inherited from Tagger: `Tag`, `TagManager`, `File` (sidecar metadata),
  `FileManager` (folder scan, filtering, ignore patterns), 3-level config,
  `HardlinkManager` (create/sync/cleanup), pytest suite.
- Rename Tagger → Curator done across code, spec, config filenames
  (`.Curator.!gtag` / `.Curator.!ftag`) and tests.
- **PySide6 GUI** (`src/ui/qt_app.py`) reframed around the Filmotéka workflow is
  the entry point; the old tkinter `src/ui/gui.py` is retained for reference.
- **Pool + Filmotéka wired up:** global config holds `pool_dir` / `filmoteka_dir`;
  `FileManager` creates `Filmy`/`Seriály`, imports movies (copy → `Title.ext`),
  loads the pool, and the GUI generates the Filmotéka tree via `HardlinkManager`.
- `File` carries `title` + `csfd_link`. **Pool metadata lives in a unified index**
  (`<pool>/.Curator.!index`, see `pool_index.py`); `File` writes there when an
  index is injected. Without an index a `File` is an in-memory object only — the
  old per-file `.!tag` sidecars and the per-folder `.!ftag` config have been
  removed.

### GUI decision

The GUI was **reframed around the Filmotéka** (not kept as a generic tagger) and
**rewritten in PySide6**: Pool/Filmotéka setup, Import movie, tag-filter sidebar,
movie table, and one-click Filmotéka generation.

## Design decisions

- **Metadata storage:** one **unified metadata file** for the whole pool (a
  central index), not per-file sidecars. Justified because Curator owns the pool
  and files are never moved manually, so it is not exposed to path drift.
- **The record is the movie, files are its children** (index **v2**,
  `movie.py`). Keyed by identity (`tmdb-<id>`, else a `name-<slug>` fallback),
  each record holds the metadata *and* a `media` list of its files with a free
  `label` per version. Chosen after the v1 path-keyed shape made multi-version
  movies unworkable: metadata rode on one file, so it had to be rescued when
  that file went, and retitling a grouped movie had to be forbidden. With
  identity as the key, `Movie.desired_layout()` is a pure function of the
  record — **one video → flat, two or more → own folder** — so promote, demote
  and rename are the same operation, and an import can recognise "this tmdbid
  is already in the pool" instead of silently creating a duplicate.
- **Config split by scope:** the global config (`.Curator.!gtag`) holds **app
  data only** — window state, MRU folders, and the `pool_dir` / `filmoteka_dir`
  pointers (which must stay global: the index is found *through* them). Everything
  that describes a specific library — `tag_schema` and `copyasis_folders` — lives
  in the pool index under a `settings` section, so it travels with the pool.
  `FileManager` migrates any pre-existing global values into the index on first
  open. The old per-folder `.!ftag` config and per-file `.!tag` sidecars were
  removed (they were unused Tagger leftovers), and the orphaned tkinter
  `src/ui/gui.py` went with them.
- **Import dialog:** **multi-file** — pick several videos at once and give each
  its own **Title** + **ČSFD link** (one row per file, more can be added from the
  dialog), or auto-filled with **"Najít ČSFD odkazy"** (cleans each filename into
  a query and fills the first ČSFD search hit; existing links are kept). A single
  **copy/move** toggle decides whether the sources are copied (default) or moved
  into the pool. Each file is renamed to `Title.ext`. When a
  ČSFD link is given, Curator fetches the movie and assigns Žánr / Rok / Země
  původu / Hodnocení (ten-point band) tags automatically; further tags can be
  added via the UI. Directors and the first 10 actors are fetched and cached too,
  but **deliberately not turned into tags/folders** (there would be too many).
- **Genres / countries:** a movie can have **multiple genres** and, for a
  co-production, **multiple countries of origin** (ČSFD writes them
  slash-separated, e.g. "USA / Velká Británie"). Each becomes its own tag, so the
  film appears under every matching genre and country branch in the Filmotéka
  (multiple hardlinks).
- **Pool layout:** two top-level folders — **Filmy** and **Seriály**. Movies are
  the first target; the Seriály branch follows the "copy-as-is" rule below.
- **Copy-as-is folders (Seriály):** a subfolder inside the pool can be marked as
  **copy / as-is**. For such a folder Curator does **not** build a tag-based tree;
  instead it **mirrors the exact directory hierarchy** from the pool into the
  Filmotéka output, with the files materialized as **hardlinks** into the pool.
  So `pool/Seriály/...` is cloned 1:1 into `output/Seriály/...` (same structure,
  hardlinked files). This is how Seriály work.
- **File naming:** pooled movies follow the convention **`Title (YYYY).ext`** — a
  clean title plus a four-digit year in parentheses (`naming.py`:
  `canonical_pool_stem` / `parse_pool_stem`). The year lets two same-named films
  coexist and makes the filename self-describing (`File.name_context` recovers
  the year from the filename when no ČSFD/tag year is present). The GUI **import
  requires a four-digit year** (per-row *Rok* field, pre-filled from the source
  filename and fillable from ČSFD — a ČSFD-suggested year is tinted blue to be
  verified, a name colliding with the pool is tinted red). *Filmy → "Přejmenovat
  dle ČSFD (rok)…"* (`FileManager.rename_all_to_canonical`) brings older
  `Title.ext` files up to the convention from their ČSFD metadata; files without
  a known year are skipped. `File.title` always stays the clean title (no year).
- **Import copy vs move:** by default the original file is **copied** into the
  pool (non-destructive); the import dialog also offers a **move** option that
  relocates the source into the pool instead.
- **Filmotéka tree layout:** driven by a category → root-folder map
  (`FILMOTEKA_CATEGORY_ROOTS`). At the output root sit the **genre folders
  directly** (`output/Akční/film`, …), next to the copy-as-is mirrors
  (**Seriály**), plus two grouping folders: **`Dle roku`** (`output/Dle
  roku/<rok>/film`) and **`Dle země původu`** (`output/Dle země
  původu/<země>/film`), plus `Dle hodnocení`. Each is a hardlink.
  `HardlinkManager` supports an empty root (tag folders placed directly at the
  output root) and restricts obsolete cleanup to the tag-tree's own top-level
  folders so mirrors are never touched.
- **Tag schema (config-driven, not hard-coded):** the categories, their ČSFD
  source field + transform, and their Filmotéka folder mapping all live in
  `tag_schema` in the global config (default `config.DEFAULT_TAG_SCHEMA`, edited
  via *Nastavení → Tag schéma…*). Both `apply_csfd_tags` (which fields → tags)
  and the Filmotéka layout (`FileManager.filmoteka_category_roots`) read from it,
  so adding a category or changing a folder rule needs no code change. A category
  can be made filter-only (no folders) by setting its `filmoteka_root` to null.
  The `transform` (e.g. `decade_band`) shapes only the **folder name** — tags keep
  the **exact value** (rating → tag `Hodnocení/90`, folder `Dle hodnocení/90–100 %`);
  it is applied at Filmotéka generation via `filmoteka_category_transforms`.
- **Filmotéka link naming (clean title, year on collision):** the default
  hardlink name in the tag tree is the movie's **clean title** — `Title.ext`,
  *not* the pooled `Title (YYYY).ext`. When two different films would collide on
  that name **within one folder**, the colliding ones keep the disambiguating
  **year** (`Title (YYYY).ext`); a residual same-title-and-year clash gets a
  stable numeric suffix. `HardlinkManager._plan_links` resolves the whole tag
  tree to a collision-free `(file, path)` plan that **both** link creation and
  obsolete-detection consume, so they can never disagree on a name (the previous
  churn source). Copy-as-is mirrors (Seriály) are unaffected — they mirror 1:1.
- **Per-category filename template** (`filename_template` in a schema entry):
  overrides the default naming **inside that category's folders only**, rendered
  from the movie's metadata (`File.name_context`: title/year/rating/ext/stem/
  filename plus any free-form attributes), e.g. a Kolekce with
  `"{collection_sort} - {title}{ext}"`. Applied via
  `filmoteka_category_filename_templates`.
- **Free-form per-movie attributes** (`File.attributes`, set in the GUI): arbitrary
  `key → value` metadata stored in the index and merged into `name_context`, so
  custom fields like `collection_sort` can drive filename templates.
- **Tag provenance (ČSFD vs user):** each file records which tags came from ČSFD
  (`csfd_tags`). Re-fetching regenerates only those; user-added tags are kept, so
  changing a movie's ČSFD link refreshes ČSFD tags without losing manual ones.
- **Special folders + "- " prefix:** besides the tag tree, generation produces
  `- Tipy dne` (15 random) and `- Nově přidané` (10 newest by `File.added`, mtime
  fallback — ctime is bumped by hardlinking). All grouping folders and these
  specials are prefixed with **"- "** so
  DLNA/TV browsers sort them before the genre folders at the output root. Specials
  are `reserved_subfolders` so cleanup never touches them; renaming old unprefixed
  folders is handled automatically (they become stale root-level folders and are
  swept on the next generation).
- **Date added:** `import_movie` stamps `File.added` (ISO); older items without it
  fall back to the file's mtime for the "recently added" ordering (ctime is
  unreliable — creating the Filmotéka hardlinks bumps it).

## Direction — Jellyfin pivot (in progress)

Curator is being refocused from a ČSFD-tagging tool into a **Jellyfin-first
library manager**. Agreed shape:

- **Pool = the Jellyfin library set.** Files are named `Title (rok) [tmdbid-N].ext`
  — the form Jellyfin matches on. Libraries are physical top-level pool folders,
  each with a **kind** (`libraries` setting; managed in *Pool → Knihovny…*):
  - `movie` — single-file movies, TMDb naming (done)
  - `series` — series/season/episode tree, mirrored 1:1 (done)
  - `mixed` — movies **and** series in one folder (Jellyfin "Mixed" type;
    supported-but-discouraged by Jellyfin, but low-risk here thanks to the strict
    structure, and fully reversible — see decisions). **Scanning TBD (phase 9).**
  - `homevideo` — files with no TMDb (Jellyfin "Home videos" type). **TBD (ph. 8).**
- **Target library layout (the user's plan):** `Hlavní` (mixed, incl. kids),
  `Dokumenty` (mixed, mostly no-TMDb YT series), `Anime` (series), `Chajda`
  (homevideo). Kids are **not** a separate folder — see decisions.
- **Naming convention:**
  - Movie: `{CZ název} (rok) [tmdbid-N].ext` — the exact Jellyfin form. A 3D
    movie carries an extra `.3D.<FORMAT>` tag before the extension (Jellyfin's
    own convention; `FORMAT` ∈ `HSBS`/`FSBS`/`HTAB`/`FTAB`/`MVC`), set via the
    edit dialog and preserved across every future rename like the tmdbid is.
  - **Multiple movie versions** (2D+3D, 4K+1080p, …): identity is
    `(title, rok, tmdbid)`, stays a **flat file** at one version. A second
    version promotes it to Jellyfin's required per-movie folder — every file
    prefixed with the exact folder name — `Title (rok) [tmdbid]/Title (rok)
    [tmdbid] - {popisek}.ext`; a 3D version's popisek doubles as its 3D tag
    (`3D HSBS`, scanned by Jellyfin the same as the flat `.3D.HSBS` form).
    Curator does the promotion/demotion itself (*Upravit film → Verze*), and a
    version's popisek is renamable too (`rename_movie_version`) — a flat movie
    always shows one placeholder row ("Výchozí") in the list even though it
    has no on-disk label yet, but renaming only applies once it's grouped. A
    popisek left empty (a plain "2D" file with nothing else to call it) is
    `DEFAULT_VERSION_LABEL` ("Výchozí"), not an error — everywhere a popisek is
    entered (`add_movie_version`, `rename_movie_version`, `merge_as_version`,
    the import dialog's version link). Promoting/demoting always carries the
    file's *own* current 3D formát over automatically when no popisek is
    given for it (`existing_label`/`keep_label` default to `None` → derived
    via `naming.parse_3d_format`) — a movie can freely gain and lose versions
    in any order (3D-only → +2D → -3D → 3D-only again, …) without a formát
    ever getting silently dropped along the way.
    The default (plain) version of a grouped movie carries **no label**:
    `Folder/Folder.ext` (`file_manager._version_filename`); "Výchozí" is the
    UI's name for it. Identity — what decides "is this film already in the
    pool" — is the folder name for a grouped movie and the stem minus any
    `.3D.<FORMAT>` for a flat one (`FileManager._identity_stem`,
    `pooled_with_stem`). Importing a film that's already there defaults to
    adding a version, never a root-level duplicate, and "keep both as separate
    films" is not offered for same-TMDb-id films (they'd share one index record).
    **Parts** (one film split across files, Jellyfin "stacking") are versions
    with a `partN` popisek, written as `Folder-partN.ext` instead of
    `Folder - popisek.ext` (`file_manager._version_filename`,
    `movie.normalize_part_label`); a film with parts always lives in its own
    folder. Parts and versions in one folder are not combined yet.
    *Upravit film* presents this as one "Média filmu" section: flat
    ("Samostatný film") until a second medium arrives, then a folder whose
    mode is switched between versions and parts (`movie_group_mode`,
    `set_movie_group_mode`); parts are reordered with ↑/↓ (`move_movie_part`).
    Renames after a relabel go through `File.save_location`, never a plain
    `save_metadata`, so a stale sibling can't overwrite shared metadata.
    Custom per-movie attributes are no longer editable in the GUI; stored ones
    still feed the miniDLNA filename templates.
    The table always shows one row per movie (`visible_movies`), marked `▣` /
    `Film · N verze` when it has several; shared metadata lives on the movie
    record (index v2), so every version reads the same. Accidental duplicates
    (same tmdbid / title+year / file size as separate movies) are found by
    *Nástroje → Kontrola duplicit* and folded in via `merge_as_version`.
    **Not yet supported:** renaming/moving/retitling a grouped movie (remove
    the version or edit files directly).
    Works in `mixed` libraries too, disambiguated from a series by **shape**:
    a movie's version folder and a series folder are both
    `Title (rok) [tmdbid]/`, but a series always nests episodes in a
    `Season NN`/`Specials` folder and a movie's version folder never does
    (`series.looks_like_series_folder`) — `load_pool_movies`/
    `is_movie_group_member` read the shape and `scan_series`
    (`skip_movie_folders=True` for `mixed`) skips what it recognises as a
    movie, so both kinds can share one identity-named folder pair without
    either leaking into the other's listing. A `series`-kind library (which
    never holds movies) keeps reading every subfolder as a series regardless
    of shape, so a raw not-yet-renamed import can still have loose episode
    files at the series root before `Season NN` exists.
    Assignable at **import** time too, not just after the fact: picking
    several files for the same film in one batch (*Importovat filmy…*), a
    row's "🔗 Přiřadit jako verzi…" marks it a version of another row instead
    of importing it as its own movie — the earlier attempt at this (a 3D
    formát combo per row) was rejected because a lone row has nothing to
    attach the version *to* and just created a duplicate; picking the target
    row explicitly is what that was missing. The popisek is pre-filled from
    the filename (`naming.three_d_format_from_filename`) the same way
    `year_from_filename` pre-fills the year. Import runs the target rows
    first, then folds each linked row onto its target via
    `add_movie_version`. The reverse case — a film whose only file *is* 3D,
    with nothing to link it to — gets its own **3D formát combo per row**
    instead (`import_movie(..., format_3d=…)`, same as *Upravit film*);
    disabled the moment the row is linked as a version or gains one as a
    follower, since a grouped movie's 3D-ness lives on the version's popisek,
    not on the row that started the group.
  - Series: `{název série} (rok) [tmdbid]/Season NN/S{ss}E{ee} - {série}.ext`
    (season 0 → `Specials`). The episode filename is the code + the series title
    only — the release string is dropped (identity is the code; Jellyfin fetches
    episode metadata from TMDb via the code + `[tmdbid]`). Episode numbers are
    recognised from the filename and editable at import / in the series GUI;
    *Seriály → "Napravit názvy souborů…"* bulk-fixes the whole pool.
  - **Episodes split into physical parts** (an old recording cut into
    several files) get Jellyfin's own `.ptN` stacking suffix —
    `SxxEyy - {série}.ptN.ext` — recognised from *cd/dvd/part/pt/disc/disk* +
    a number in the source filename (`Show.S01E02.pt2.mkv`,
    `Show S01E01-part-1.mkv`, …) or typed by hand at import as `S01E02P3`
    (`src.core.series.parse_episode_code`/`parse_episode_part`). Distinct from
    a multi-episode file (`E01-E02`, one file = several episodes) — a part is
    the opposite: several files = one episode.
  - **Removing a series is scoped to the tree selection**: *Přehled seriálů →
    "Odebrat z poolu…"* deletes the series, a single season, or a single
    episode, whichever is selected (`FileManager.remove_series`/
    `remove_season`/`remove_episodes`) — series still carry no index metadata,
    so this is always just deleting files/folders from disk.
  - **CZ title source:** TMDb (cs-CZ) **primarily** — reliable when matched by
    `tmdbid` (yearless title search picks the wrong film, hence the earlier
    "weird names"); **ČSFD as fallback/override** (a ČSFD link at import, or when
    TMDb has no cs title); last fallback = the original filename. The filename is
    always editable in the GUI.
- **Metadata is Jellyfin's job**: Jellyfin fetches from TMDb and (configured to)
  writes `.nfo` + artwork into the folders → survives a Jellyfin reinstall.
  Curator resolves a **TMDb id → title + year** for naming (`tmdb.py`). ČSFD is
  kept **only** as a title source (not for tags/matching — it exposes no
  TMDb/IMDb id, verified): it feeds the **ČSFD → TMDb bridge** (`csfd.py`,
  `FileManager.resolve_via_csfd`) — filename → ČSFD search → ČSFD *original*
  title + year → TMDb search → tmdbid, more reliable than a raw Czech-title
  TMDb search. Used by the import dialog ("Dohledat přes ČSFD") and by migration
  for any movie with a stored `csfd_url`.
- **Import:** mandatory **TMDb id** (matching + CZ title), optional **ČSFD link**
  (drives the ČSFD→TMDb bridge, and stored as a pointer); filename hand-editable
  before/after import. The import row is pre-filled on open (no network) from
  metadata already next to the source file: Curator's **pre-index** layouts —
  a `.{filename}.!tag` sidecar or an old `.Curator.!index` up the tree
  (`legacy_meta.read_legacy_meta`, authoritative for the ČSFD link) — then a
  Kodi/Jellyfin `.nfo` (`nfo.read_nfo`, also reads a `csfd` `uniqueid` /
  `<csfdid>`, and supplies the TMDb id).
- **miniDLNA**: keep a genre-split **hardlink tree** for a dumb DLNA browser,
  but drive it from the **NFO** Jellyfin wrote (repurposing `HardlinkManager` +
  `naming.py`), not from ČSFD tags. **Scoped per library** (*miniDLNA →
  "Knihovny pro generování…"*, `minidlna_libraries` in the pool index, default
  = all) — lets a library (e.g. Kids) be excluded from the dumb-DLNA output
  entirely; a movie library's genre-tree links are swept as obsolete the normal
  way when it's excluded. A `series` **or** `homevideo`-kind library has no
  genre tags to build a tree from (homevideo has no TMDb id either), so both
  hardcopy whole into `output/<jejich vlastní název>` (`mirror_as_is_libraries`)
  — this works today independent of phase 8 (homevideo needs no GUI
  import/browse support to be mirrored). Mirrors have **no obsolete-link
  mechanism of their own**, so excluding one is pruned explicitly
  (`FileManager.minidlna_prune_targets` + `HardlinkManager.remove_mirror`) —
  including the shared `output/Seriály` bucket a mixed-library series and a
  same-named real library can both write into, reconciled per-entry so pruning
  one never erases the other's still-valid content.
- **Jellyfin API** (thin, hybrid): trigger scans, verify, manage collections;
  key + URL in `.env`. NFO on disk stays authoritative.
- **Subtitles stay external, never muxed** (`subtitles.py`): a `.srt`/`.ass`/
  `.ssa`/`.sub`/`.vtt` sharing the video's stem (+ optional `.lang`/`.forced`/
  `.sdh`/`.default`) plays natively in Jellyfin — no re-encode, multiple
  languages side by side, easy to replace. Presence is read live from disk
  (like NFO), not cached in the index. The one thing Curator owns: a subtitle
  **follows its video through every rename/move** so it never silently
  detaches (every rename/move path calls `subtitles.rename_subtitles_with`).

### Decisions (locked)

- **Kids = Jellyfin parental rating, not a folder** (variant B). Kids content
  stays in the normal libraries; a child Jellyfin account gets a max-rating limit
  with **"block unrated" ON**. Ratings come from TMDb via Jellyfin. Caveat: Czech
  certifications are sparse — set the library metadata country to one with fuller
  ratings (US) and fix odd cases in Jellyfin (Identify + lock).
- **Mixed libraries are OK and reversible.** Jellyfin discourages them (unreliable
  metadata) but our disciplined structure (series = `Season/SxxEyy`, movie =
  single file + `[tmdbid]`) gives the scanner clear signals. Because metadata is
  **NFO on disk** + **tmdbid in the name**, switching mixed↔separate later is just
  moving folders (Jellyfin re-reads NFO, no re-fetch, no loss).
- **Home videos** (Chajda) use Jellyfin's **"Home videos"** content type — no
  online lookup, just serves the files.
- **Always match by tmdbid, not by yearless title.** TMDb cs-CZ titles are good
  when the right film is matched (lookup by id, or search with a year); a bare
  title search trips on remakes/same-name films (verified: Home Alone → 2021
  reboot, Vejška → 2006). Import supplies the id; migration searches with a year.

### Phasing

(1) TMDb identity + tmdbid naming + import rework [done]; (2) movie libraries as
physical partitions + import-into / move-between [done]; (3) Jellyfin API — scan +
verify + status [done]; (4) miniDLNA genre tree from NFO + ČSFD removed [done];
(5) series model — SxxEyy layout, import, rename [done]; (6) migrate the existing
pool — title+year → TMDb search → tmdbid [done]; (7) consolidated edit dialogs +
library organizer (unified `libraries` model with kinds) [done]; (9) mixed-library
scanning + generation (movies + series in one folder) [done].
Remaining: **(8) import without TMDb/year** (homevideo, no-TMDb docs).

Note: libraries hold **flat** files for now (`pool/<Library>/Title (rok)
[tmdbid].ext`); per-movie folders are a later refinement.

## Tasks

### Phase 8 — import without TMDb / without year (homevideo, no-TMDb docs)

- Relax the import dialog: allow a row with **no year and no tmdbid** (currently
  a 4-digit year is mandatory). Pool name then falls back to `Title.ext`
  (movies) / `Series/Season NN/SxxEyy.ext` (series), no `[tmdbid]`.
- Drive this by **library kind**: `homevideo` (and no-TMDb rows in `mixed`)
  skip the TMDb requirement; `movie` keeps requiring a year (as today).
- `homevideo` library scanning: load its files as items (flat), no TMDb naming,
  no genre tags. Consider a dedicated import path or a per-import "bez TMDb" toggle.
  **miniDLNA generation for `homevideo` needs none of this** — it hardcopies the
  whole library folder as-is (`mirror_as_is_libraries` **[done]**); this task is
  only about GUI import/browsing.
- Tests: import with no year/id lands correctly; homevideo library loads.

### Phase 9 — mixed-library scanning + generation

- Scanning **[done]**: a `mixed` library's top-level files load as movies
  (`load_pool_movies`), its subfolders as series (`load_series` /
  `series_libraries` = kind `series` **or** `mixed`, reusing `scan_series`) —
  *except* a canonical-shaped subfolder with no `Season NN`/`Specials` inside
  it, which is a movie's version folder instead and loads as a movie too (see
  "Multiple movie versions" above). Both are kind-aware over the unified
  `libraries` list. The library filter / table already surfaces mixed
  libraries.
- miniDLNA generation **[done]**: a mixed library's movies are genre-tagged as
  usual; series in its subfolders have no genre tags, so they're hardcopied
  straight into `output/Seriály/<název>/…` instead
  (`FileManager.minidlna_scope` → the mixed-library series list; the mirror
  loop in `generate_filmoteka`). NFO refresh needs no separate handling — it
  only ever touches movies (`self.filelist`), series never go through NFO/TMDb
  tagging, mixed or not.
- Tests: a mixed folder with both a movie and a series loads/generates
  correctly **[done]** (`TestMinidlnaScope` in `test_file_manager.py`).

### Later / optional

- **ČSFD → TMDb title bridge (done).** A direct TMDb search on a Czech title was
  matching the wrong film too often, so a lean `csfd.py` was revived (Anubis PoW
  solver, film-page + search parsing, `original_title` extraction — the entry in
  `.film-names` whose flag matches the country of origin). `resolve_via_csfd`
  drives it from the import dialog and from migration. **Not** a return of ČSFD
  tags — genres still come from TMDb via Jellyfin/NFO. Open follow-up: batch
  "look up ČSFD links for the whole pool" as a migration pre-pass (today the
  `csfd_url` is per-movie, set at import / in the edit dialog).
- Per-movie folders (`pool/<Lib>/Title (rok) [tmdbid]/…`) instead of flat
  files — **partially done**: a movie only gets its own folder once it has a
  second playable version (see "Multiple movie versions" below); a single-file
  movie stays flat as before.
- Collections / BoxSets (Bond, Marvel) via Jellyfin API or `<set>` in NFO.
- Optional common umbrella folder above libraries (`pool/Média/<Lib>`) — needs
  path-aware `library_of` (currently single-segment).

## Done

- Jellyfin pivot phases 1–7 (see Phasing): TMDb identity, tmdbid naming, movie
  libraries + move, Jellyfin API (scan/verify), NFO-driven miniDLNA + ČSFD
  removed, series model (SxxEyy), pool→TMDb migration, consolidated edit dialogs
- Phase 9 — mixed-library scanning + generation: a `mixed` library's top-level
  movies genre-tag as usual, series in its subfolders hardcopy into
  `output/Seriály/<název>/…` (no genre tags apply to a series)
- Library organizer (`libraries` unified model with kinds movie/series/mixed/
  homevideo; *Pool → Knihovny…*); `movie_libraries`/`copyasis_folders` derived
- Pool naming convention `Title (YYYY).ext` (`naming.py`): year required at
  import (per-row Rok field, blue = ČSFD-suggested, red = pool collision), plus
  "Přejmenovat dle ČSFD (rok)" to bring older files up to the convention
- Video integrity check (`integrity.py`, Testy → "Kontrola integrity videa"):
  FFmpeg-based scan for corrupted/unreadable video data, deep (full decode) or
  quick (ffprobe), over selected movies or the whole pool
- Pool-root and Filmotéka-output folder settings in the global config
- Filmy / Seriály top-level folder handling in the pool
- "Import movie" dialog (Title + ČSFD link), copy into pool/Filmy as Title.ext
- Rename a pooled movie from the app (`FileManager.rename_movie`): renames the
  file in pool/Filmy and moves its metadata to the new index key
- Remove-from-pool (delete file + its metadata)
- Generate the Filmotéka hardlink tree from the pool (Rok / Žánr / Země původu /
  Hodnocení)
- Filmotéka fully regenerable from the pool alone (delete output = no loss)
- GUI reframed around the Filmotéka and rewritten in PySide6
- Seriály "copy-as-is" mirror: pool/Seriály cloned 1:1 into the output as
  hardlinks (`HardlinkManager.mirror_as_is`), wired into Filmotéka generation
- Fixed `media_utils` missing `subprocess` import
- Unified pool metadata index (`pool_index.py`): one `.Curator.!index` per pool;
  `File` reads/writes it when injected, `FileManager` uses it for the pool
- Configurable copy-as-is folders (`copyasis_folders` in global config, editable
  from the GUI); each is mirrored 1:1 during Filmotéka generation (Seriály default)
- README.md written (overview, concepts, workflow, run/build instructions)
- ČSFD scraping (`csfd.py`, ported from Tagger devel): `File.apply_csfd_tags`
  fetches a movie and assigns Žánr / Rok / Země původu tags (cached in metadata); wired
  into the GUI (auto-fetch on import with a ČSFD link, plus "Načíst tagy z ČSFD").
  Parsing updated for current ČSFD HTML and verified live against Matrix
  (film/9499); HTTPS uses the OS cert store via `truststore` (corporate SSL)
- ČSFD Anubis anti-bot wall handled: `csfd.py` detects the proof-of-work
  challenge page, solves it (SHA-256 PoW matching the bundled worker JS) and
  replays via a shared `requests.Session`, so Žánr / Rok / Země původu tags load again
  (the "nalezeno 1 film, načteno 0 tagů" symptom). Verified live (Matrix 1999)
- Removed the inherited Tagger predefined tags: `DEFAULT_TAGS` is now empty
  (no Hodnocení ⭐ / Barva categories) and new files no longer get an automatic
  `Stav/Nové` tag. Tags now come from ČSFD (Žánr / Rok / Země původu) and manual edits.
  Note: `Hodnocení` is still listed in `FILMOTEKA_CATEGORIES`, so that branch is
  simply empty until something assigns a Hodnocení tag again
- Fixed template cruft: `src/constants.py` made consistent (Curator values,
  `get_version`/`get_debug_mode` API) and `test_constants.py` aligned; removed
  the imported `tagger/` devel dump
