# 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, and still falls back to per-file `.!tag` sidecars for
  arbitrary (non-pool) folders.

### 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.
- **Import dialog:** collects only **Title** + **ČSFD link**. The file is renamed
  to `Title.ext`. When a ČSFD link is given, Curator fetches the movie and assigns
  Žánr / Rok / Země tags automatically; further tags can be added via the UI.
- **Genres:** a movie can have **multiple genres**, so it appears under each of
  its genre branches 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:** imported movies are renamed to **`Title.ext`** (no year in the
  filename; year lives in metadata/tags).
- **Import is non-destructive:** the original file is **copied** into the pool,
  the source is left in place.
- **Filmotéka tree:** **one level per category** — `output/Category/Tag/film`
  (hardlink), same shape as the current hardlink manager. For now the tree is
  built from these categories: **Rok**, **Žánr**, **Hodnocení**.

## Tasks

# (no open tasks — see Done)

## Done

- 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
- Remove-from-pool (delete file + its metadata)
- Generate the Filmotéka hardlink tree from the pool (Rok / Žánr / 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 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)
- 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
