chore: odstranit resources.py a konfiguraci flake8 z balíčku (v2.1.4) (#71)

* chore: odstranit resources.py a konfiguraci flake8 z balíčku

Scanner na plugins.qgis.org označil plugin jako „Validated
(configured)“ kvůli amcr_viewer/.flake8. Ten potlačoval jen stylové
nálezy (E302, E305, E501) ve vygenerovaném resources.py, který se
nikde neimportuje – ikony se načítají přímo z PNG. resources.py
repozitář pluginů nevyžaduje (validator.py v QGIS-Django, PyQGIS
cookbook: „optional“).

- Smazán amcr_viewer/resources.py a amcr_viewer/.flake8.
- CI: flake8 běží s --isolated (výchozí pravidla jako scanner);
  kontrola ZIPu místo .flake8 hlídá povinný LICENSE.
- check_sources.py: žádné skryté soubory v balíčku, ani config
  soubory scanneru.
- pyproject.toml, README.md, AGENTS.md: odstraněny odkazy na oba
  soubory, popsán postup bez konfigurace.

Ověřeno: check_sources, flake8 7.3.0, ruff 0.16.5, bandit 1.9.4,
detect-secrets bez nálezů; pyqgis4-checker čistý; smoke test v QGIS
3.44.15 (Qt 5) i 4.2.3 (Qt 6); ZIP bez skrytých souborů.

Připraveno s pomocí AI (Claude).

* Verze 2.1.4

Povýšena verze v metadata.txt (+ changelog) a CITATION.cff po odstranění resources.py a konfigurace flake8.

Připraveno s pomocí AI (Claude).

+Pokyny pro AI agenty i lidské přispěvatele pracující v tomto repozitáři.
+Tento soubor je jediný zdroj pravdy; `CLAUDE.md` na něj pouze odkazuje.
+
+## O projektu
+
+**AMČR Viewer** je plugin do QGIS pro stahování a vizualizaci dat z Digitálního
+archivu Archeologické mapy ČR (AMČR / AIS CR) – akce (*Fieldwork events*),
+lokality (*Sites*) a jejich komponenty. Podporuje anonymní i přihlášený přístup
+přes AMČR účet.
+
+Zdroj dat: https://digiarchiv.aiscr.cz/ · Nápověda: https://amcr-help.aiscr.cz/digiarchiv/qgis-viewer.html
+
+## Zařazení v ekosystému AIS CR
+
+Tento repozitář je jedním ze **sourozeneckých repozitářů** ekosystému AIS CR.
+Centrální governance a AI konfigurace spravuje hub **`aiscr-management`**; konvence
+v tomto souboru jsou s tímto vzorem sladěné a zjednodušené pro potřeby jednoho
+QGIS pluginu. Těžkou mašinerii hubu (složka `.agents/`, OpenSpec, sync skripty,
+multi-assistant generování) tento repozitář **záměrně nepřebírá**. Při širších
+otázkách governance má přednost vzor z `aiscr-management`.
+
+## Struktura repozitáře
+
+```
+amcr_viewer/            # vlastní kód pluginu (toto se balí do releasu)
+  amcr_viewer.py        # vstupní bod pluginu, integrace do QGIS
+  amcr_dialog.py        # dialogy a UI (filtry, přihlášení)
+  amcr_tools.py         # stahování dat z API, sestavení vrstev a atributů
+  amcr_codelists.py     # hesláře / číselníky (codelists)
+  codelists/heslar.csv  # lokální kopie číselníků
+  metadata.txt          # metadata pluginu + verze + changelog
+  i18n/                 # překlady (.ts)
+  *.png                 # ikony
+.github/workflows/      # CI – release pluginu
+README.md               # uživatelská dokumentace (anglicky)
+```
+
+## Konvence
+
+### Jazyk
+- **Kód a identifikátory:** anglicky. Atributová pole vrstev musí být ASCII
+  kompatibilní (bez diakritiky) – viz historie změn v `metadata.txt`.
+- **README a uživatelská dokumentace:** anglicky.
+- **Commity, PR a komentáře v issue:** česky.
+
+### Commity
+- Styl odpovídá historii: česky, věcně, popisně; jeden commit = jedna logická
+  změna.
+- První řádek stručně a výstižně (ideálně v imperativu); podrobnosti do těla.
+- Pokud je commit připraven s pomocí AI, uveď to v těle commitu nebo v popisu PR.
+
+### Větve
+Konvence názvů je sladěná s hubem `aiscr-management`:
+
+- **lidé:** `feat/<téma>` (nová funkce), `fix/<téma>` (oprava), `docs/<téma>`
+  (dokumentace), `chore/<téma>` (údržba).
+- **AI agenti:** `agents/<jméno-agenta>/<téma>` (např. `agents/claude/oprava-pian`).
+
+Další pravidla:
+
+- Cílová větev pro nový vývoj je aktuální `version/v2.x.y` (ne přímo do
+  výchozí větve bez PR).
+- **Nikdy** nepushuj přímo do chráněných větví; vždy přes Pull Request.
+- Standardizační / nefunkční změny drž v samostatné větvi, ať se nemíchají do
+  feature PR.
+
+### Pravidla pro AI agenty (git)
+- AI ve výchozím stavu zůstává u **lokální práce na aktuální větvi**.
+- Bez **výslovného pokynu** uživatele AI nestageuje (`git add`), necommituje,
+  nepushuje ani samo nepřepíná/nezakládá větev pro vzdálené doručení.
+- Při výslovném požadavku na push/PR použij větev `agents/<jméno-agenta>/<téma>`;
+  pokud aktuální větev tomuto vzoru neodpovídá, vyžádej si nejdřív potvrzení.
+- Vytvoření větve, stage, commit, push ani draft PR AI běžně nenabízí; zmiňuj je
+  jen tehdy, když jsou pro splnění úkolu opravdu nutné.
+
+### QGIS specifika
+- Minimální podporovaná verze QGIS je **3.44** (`qgisMinimumVersion` v
+  `metadata.txt`); kód nesmí spoléhat na novější API.
+- Vrstvy a atributy se sestavují přes `QgsField` / QGIS API v `amcr_tools.py`.
+  Při přidání atributu je potřeba doplnit ho konzistentně na všech místech:
+  definice pole (`QgsField`), naplnění hodnoty z dokumentu, překlad hlavičky
+  sloupce a export atributů.
+
+### Kompatibilita s Qt6 / QGIS 4
+
+Plugin cílí na QGIS 3.44 i na QGIS 4 (`qgisMaximumVersion=4.99.0`), tedy na
+Qt5 i Qt6 zároveň. **Tohle se drží rigorózně** – ne až před releasem, ale při
+každé změně kódu. Chování obou větví se liší tiše: pod Qt5 projde i to, co
+QGIS 4 odmítne, takže lokální „funguje mi to“ nic nedokazuje.
+
+Závazná pravidla:
+
+- **Nikdy neimportuj přímo z `PyQt5` ani z `PyQt6`.** Vždy přes shim
+  `qgis.PyQt.*`. Ten mimo jiné pod Qt6 přetahuje `QAction`, `QActionGroup`
+  a `QShortcut` z `QtGui`, takže import z `qgis.PyQt.QtWidgets` je správně.
+- **Enumy vždy plně kvalifikované (scoped).** `Qgis.MessageLevel.Info`, ne
+  `Qgis.Info`; `QgsTask.Flag.CanCancel`, ne `QgsTask.CanCancel`;
+  `QgsWkbTypes.GeometryType.PointGeometry`, ne `QgsWkbTypes.PointGeometry`.
+  Totéž pro Qt: `Qt.CheckState.Checked`, `QDialogButtonBox.StandardButton.Ok`.
+  Zkrácené tvary sice v QGIS 4.2 zatím fungují, ale oficiální kontrola je
+  hlásí a do budoucna mizí.
+- **Zdrojové `.py` soubory ukládej bez BOM.** Kontrolní skript čte soubor
+  jako UTF-8 bez `utf-8-sig` a na BOM spadne s
+  `SyntaxError: invalid non-printable character U+FEFF`, takže se takový
+  soubor **vůbec nezkontroluje**. (`codelists/heslar.csv` BOM mít smí, tam je
+  kvůli Excelu.)
+- Nepoužívej API zrušená v Qt6: `exec_()`, `QRegExp`, `QDesktopWidget`,
+  `QApplication.desktop()`, `Qt.MidButton`, `QFontMetrics.width()`,
+  `setResizeMode`, atributy `AA_EnableHighDpiScaling` / `AA_UseHighDpiPixmaps`.
+- `supportsQt6=True` v `metadata.txt` **nepatří** – bylo zrušeno; o zařazení
+  mezi „QGIS 4 Ready“ rozhoduje rozsah `qgisMinimumVersion` až
+  `qgisMaximumVersion`.
+
+Ověření před PR, který mění Python kód:
+
+```sh
+# oficiální kontrola, kterou pouští i plugins.qgis.org (pyqgis4-checker)
+docker run --rm --pull always --user $(id -u):$(id -g) \
+  --workdir /workspace/ -v "$(pwd):/workspace/" \
+  ghcr.io/qgis/pyqgis4-checker:main-ubuntu \
+  pyqt5_to_pyqt6.py --dry_run --logfile /workspace/pyqt6_checker.log .
+```
+
+Prázdný log = čisté. Kontrola je na plugins.qgis.org informativní
+(neblokuje schválení), ale nález znamená, že plugin v QGIS 4 dříve nebo
+později přestane fungovat.
+
+Když je po ruce QGIS 4 (např. flatpak `org.qgis.qgis`), ověř navíc, že se
+plugin pod Qt6 opravdu načte:
+
+```sh
+flatpak run --command=sh org.qgis.qgis -c \
+  'PYTHONPATH=/app/share/qgis/python python3 -c "import qgis.core"'
+```
+
+## Verzování a release
+
+- Verze pluginu žije v **`amcr_viewer/metadata.txt`** (`version=`).
+- **Při každé změně chování / nové funkci** povyš verzi a doplň položku do
+  `changelog=` v `metadata.txt` (formát `vX.Y.Z (RRRR-MM-DD)` + odrážky).
+- Současně povyš i **`CITATION.cff`** v kořeni repozitáře: `version:` na
+  stejnou verzi jako v `metadata.txt` a `date-released:` na datum releasu.
+  Oba soubory musí mít stejnou verzi, než se založí tag.
+- Datum v changelogu ber z **deterministického zdroje**, ne z paměti, např.
+  `python -c "import datetime; print(datetime.date.today().isoformat())"`.
+- Release se spouští **pushnutím tagu `vX.Y.Z`**, ne publikací releasu
+  v UI. Workflow `.github/workflows/release_plugin.yml` zabalí složku
+  `amcr_viewer/` do `amcr_viewer.zip` a založí **koncept** releasu i s touto
+  přílohou; text se dopíše a release zveřejní ručně. Do ZIPu se nesmí dostat
+  `.git*` soubory.
+- Organizace má zapnuté **immutable releases** – k publikovanému releasu už
+  nelze nic přiložit. Proto příloha vzniká na konceptu, ještě před
+  zveřejněním; workflow spouštěný na `release: published` by vždy selhal.
+- Workflow se čte z commitu, na který **tag ukazuje**. Tag proto zakládej až
+  na commitu, který obsahuje aktuální podobu workflow – jinak se nespustí nic.
+
+## Pull requesty
+
+- Používej PR šablonu (`.github/pull_request_template.md`): Souhrn / Změny /
+  Testování / Kontrolní seznam.
+- PR musí mířit do správné `version/v2.x.y` větve.
+- Před požádáním o review projdi kontrolní seznam v šabloně (zejména bump verze
+  v `metadata.txt`, pokud měníš chování).
+- V popisu PR uveď **podíl AI** (např. „text navržen AI, ručně zkontrolováno")
+  a odkaz na související issue, pokud existuje.
+
+## Bezpečnost a soukromí
+
+- Do promptů, příkladů ani commitů **nevkládej** ostrá produkční data, plné
+  log dumpy ani reálné osobní údaje (PII).
+- **Rediguj** secrets, tokeny, API klíče a hesla z čehokoli, co posíláš AI;
+  nikdy je necommituj do repozitáře (ani přihlašovací údaje k AMČR účtu).
+- Pro interní infrastrukturu (URL, hostname, prostředí) používej placeholdery,

+
+## Lokální ověření
+
+Plugin se testuje načtením do QGIS (Plugins → Manage and Install Plugins →
+Install from ZIP, nebo nasazením složky `amcr_viewer/` do adresáře pluginů
+QGIS). **Ruční test v QGIS nic nenahrazuje** – automatické kontroly ověřují,
+že se plugin načte a že projde kontrolami kvality, ne že dělá správnou věc.
+
+### Automatické kontroly
+
+Workflow `.github/workflows/code_quality.yml` pouští při každém PR do `main`
+tohle:
+
+| job | co dělá |
+|---|---|
+| **Lint a bezpečnost** | `check_sources.py`, bandit, detect-secrets, flake8, ruff |
+| **Kompatibilita s Qt6** | `pyqgis4-checker` v dockeru |
+| **Smoke test** | `smoke_test.py` v `qgis/qgis:ltr` i `qgis/qgis:stable` |
+| **Balíček pluginu** | ověří shodu verze v `CITATION.cff` a `metadata.txt`, sestaví ZIP, ověří obsah, přiloží jako artefakt |
+
+Smoke test běží v obou podporovaných řadách: `ltr` je QGIS 3.44 na Qt5,
+`stable` je QGIS 4.x na Qt6.
+
+Artefakt z posledního jobu se dá stáhnout ze stránky běhu a rovnou
+nainstalovat přes *Install from ZIP* – recenzent nemusí nic balit ručně.
+
+Totéž lokálně:
+
+```sh
+pip install bandit detect-secrets flake8 ruff
+
+python3 tests/check_sources.py
+bandit -r amcr_viewer/
+detect-secrets scan --all-files amcr_viewer/
+flake8 --isolated amcr_viewer/
+ruff check .
+
+# smoke test v obou verzích QGIS (docker, bez instalace čehokoli)
+for tag in ltr stable; do
+  docker run --rm -v "$PWD:/work:ro" -w /work \
+    --user "$(id -u):$(id -g)" -e HOME=/tmp \
+    "qgis/qgis:$tag" python3 tests/smoke_test.py
+done
+```
+
+Na co si dát pozor:
+
+- **`pyqgis4-checker` končí kódem 0, i když něco najde** – výsledek je jen
+  v logu. Workflow proto kontroluje, že log obsahuje jen hlavičku.
+- **`detect-secrets` bez `--all-files` prohledá jen soubory sledované
+  gitem** a o nesledovaném souboru mlčí. Vypadá to jako čistý výsledek.
+- **Flake8 běží bez konfigurace** (`--isolated`), tedy se stejnými
+  výchozími pravidly jako scanner na plugins.qgis.org. Do balíčku nepatří
+  `.flake8`, `.bandit` ani `.secrets.baseline`: scanner by plugin označil
+  jako „Validated (configured)“ a nález je lepší opravit v kódu.
+  Konfigurace ruffu je v kořenovém `pyproject.toml` – ruff se do balíčku
+  pluginu nedistribuuje.
+  Viz https://plugins.qgis.org/docs/security-scanning/config-files
+- **Verze nástrojů jsou v workflow napevno.** Výchozí sada pravidel ruffu se
+  mezi verzemi mění, takže bez pinu by CI začalo padat samo od sebe.

-## 1. Overview
+## 1. What it can download
 
-**AMCR Viewer** is a QGIS plugin designed to facilitate direct access to the Digital Archive of the Archaeological Map of the Czech Republic (AMČR). It allows researchers to **query, retrieve, and visualize Fieldwork events[^1] data (metadata and geometry) directly within the GIS environment**, eliminating the need to manually export data from the web interface. **Only publicly accessible data are supported at the time** (accessibility = anonymous).
+The plugin covers three AMČR record types. Each has its own menu entry, its
+own set of filters and its own attribute table.
 
-[^1]: Only Fieldwork events (Akce) are supported at the time.
+| Entity | Menu entry | What it is |
+| --- | --- | --- |
+| **Fieldwork events** (`akce`) | *Stáhnout data akcí* | Records of archaeological finds and observations tied to a place, a responsible body and a time of execution. |
+| **Sites** (`lokalita`) | *Stáhnout data lokalit* | Records tied to a site, its characteristic archaeological manifestation and presumed function. |
+| **Individual finds** (`samostatny_nalez`) | *Stáhnout data samostatných nálezů* | Records of individual movable finds reported through **AMČR-PAS**, the portal for amateur collaborators. |
 
-### Key Features
+Fieldwork events and Sites can additionally carry **component** data (period
+and activity area) directly in the attribute table. Individual finds have no
+components — period and dating are attributes of the find itself.
 
-* **Spatial Querying:** Option to filter records based on the current map canvas extent (Bounding Box).
-* **Advanced Attribute Filtering:** Supports multi-criteria filtering using controlled vocabularies (Cadastral Area, District, Period, Type of Fieldwork event, Organization, Fieldwork Manager).
-* **Dynamic Geometry Retrieval:** Automatically downloads and categorizes spatial data into Point, Line, and Polygon layers.
-* **Semantic Interoperability:** Automatically translates internal system codes into human-readable labels using the AIS CR API.
+### Key features
+
+* **Spatial querying** — restrict the query to the current map canvas extent.
+* **Multi-criteria attribute filtering** driven by AMČR controlled
+  vocabularies (*hesláře*), with a searchable multi-select picker per filter.
+* **Date range filtering** for fieldwork start/end and for the date of finding.
+* **Automatic geometry retrieval**, split into Point, Line and Polygon layers
+  and reprojected to S-JTSK.
+* **Human-readable labels** — internal codes (`HES-xxxxxx`) are translated via
+  the AIS CR translation dictionary.
+* **Authenticated access** — an AMČR account unlocks non-public records;
+  credentials are stored encrypted in the QGIS Authentication Manager.

-## 2. Installation Guide
+## 2. Installation
 
-1. Obtain the [plugin distribution package](https://github.com/ARUP-CAS/aiscr-qgis-amcr-viewer/archive/refs/heads/main.zip) (ZIP archive containing the `amcr_viewer` directory).
-2. Launch QGIS.
-3. Navigate to **Plugins**  **Manage and Install Plugins...**
-4. Select the **Install from ZIP** tab.
-5. Locate the source ZIP file and click **Install Plugin**.
-6. Upon successful installation, the AMCR download button (load AMCR data) will appear in the interface.  
+### From the QGIS plugin repository (recommended)
 
-**OR**  
+*Plugins → Manage and Install Plugins… → search for* **AMČR Viewer** *→
+Install*.
 
-Install the plugin from QGIS plugin repository.
+### From a ZIP archive (older versions, or a build from source)
+
+1. Download a [release package](https://github.com/ARUP-CAS/aiscr-qgis-amcr-viewer/releases)
+   (a ZIP containing the `amcr_viewer` directory).
+2. In QGIS go to *Plugins → Manage and Install Plugins… → Install from ZIP*.
+3. Select the archive and click *Install Plugin*.
+
+Every successful CI run also publishes a ready-to-install `amcr_viewer.zip`
+as a build artifact, which is handy for testing a branch before release.
+
+After installation the **AMČR Viewer** button appears in the toolbar as a
+dropdown.
+
+### Requirements
+
+The plugin needs the **`requests`** library. It ships with the QGIS installers
+for Windows and macOS. On Linux distribution packages it may have to be
+installed separately (e.g. `python3-requests`).

-## 3. User Manual
+## 3. User manual
 
-### 3.1 Data Retrieval
+### 3.1 Toolbar and menu
 
-To initiate a search query, click the **Load AMCR Data** icon. The filter dialog provides the following options:
+The toolbar button is a dropdown; the default action is *Stáhnout data akcí*.
 
-* **Spatial Filter:** *Checkbox "Limit search to current map extent":* If checked, the query is restricted to the geographical area currently visible in the QGIS canvas. If unchecked, the query searches the entire database (use with caution regarding data volume).
-* It is possible to view only those Fieldwork events with positive outcome, if "Positive findings only" is checked. Only PIANs marked as (or rather PIANs belonging to Documentation units marked as) "Type of evidence" = "positive" are rendered.
+| Menu entry | Action |
+| --- | --- |
+| *Stáhnout data akcí* | Opens the filter dialog for Fieldwork events. |
+| *Stáhnout data samostatných nálezů* | Opens the filter dialog for Individual finds. |
+| *Stáhnout data lokalit* | Opens the filter dialog for Sites. |
+| *Přihlásit se* | Opens the login dialog (see 3.2). |
+| *Nápověda AMČR Help* | Opens the online documentation in a browser. |
 
+### 3.2 Authentication (optional)
 
-* **Attribute Filters:**
-  * The dialog utilizes "Picker" widgets for controlled vocabularies (Region, District, Cadastral area, Organisation, Period, Activity Area).
-  * Click **Select...** to open a searchable selection window. Multiple values can be selected simultaneously (Logic: OR).
+By default the plugin sees only publicly accessible records. Logging in with
+an AMČR account extends the result set to everything the account is allowed
+to see.
 
+* The credentials are **verified against the API before they are stored** —
+  a wrong password never reaches the Authentication Manager. If the server is
+  unreachable, the plugin offers to store them unverified.
+* They are then saved encrypted in the **QGIS Authentication Manager** (DPAPI
+  on Windows, Keychain on macOS, encrypted SQLite on Linux). QGIS will ask for
+  its master password.
+* Stored credentials are reused across QGIS sessions. If the session cookie
+  expires mid-download, the plugin re-authenticates automatically and repeats
+  the request.
+* Reopening the login dialog lets you change the e-mail (leave the password
+  blank to keep the stored one) or remove the credentials entirely
+  (*Odebrat uložené přihlašovací údaje*).
 
-* **Fieldwork Manager (Dynamic List):**
-  * Due to the dynamic nature of the persons database, the list of Fieldwork Managers is retrieved from the AIS CR servers and needs to be updated the first time (and subsequently, if there is need).
-  * To refresh the list from the server, click the **Refresh (🔄)** button next to the selection field. This downloads the latest list of researchers from the API.
-* If no filter is used, all accessible Fieldwork events/PIANs are returned (although the number of Fieldwork events to be loaded is capped at 20000 records; it is advisable to set at least one filter).
+### 3.3 The filter dialog
 
+Filters of different categories are combined with **AND**; multiple values
+inside one filter are combined with **OR**. A filter left empty means "no
+restriction". Click *Vybrat…* to open a searchable, checkable list.

-Upon successful retrieval, the plugin generates three temporary memory layers:
+#### Spatial restriction
 
-1. **AMCR Plochy (Polygons)**
-2. **AMČR Linie (Lines)**
-3. **AMČR Body (Points)**
+*Omezit vyhledávání rozsahem okna* is **checked by default**. The canvas
+extent is transformed from the project CRS to WGS-84 and sent as a bounding
+box. Unchecking it queries the whole database — do so with an attribute
+filter in place, otherwise you will hit the record cap (see 4.5).
 
-The Attribute Table includes standardized fields such as:
+#### PIAN accuracy has a non-empty default
 
-* **Identification:** `Identifikátor` (Fieldwork event ID), `PIAN` (PIAN ID).
-* **Classification:** `Hlavní typ` (Main Fieldwork event Type), `Vedlejší typ` (Secondary Fieldwork event Type), `PIAN – typ` (PIAN Type).
-* **Administration:** `Vedoucí akce` (Fieldwork Manager), `Organizace` (Organization), `Datum zahájeni`/`Datum ukončení` (Dates of start and end of the Fieldwork event).
-* **Location:** `Katastr` (Main Cadastral area), `Další katastry` (Other Cadastral areas), `Okres` (District), `Definiční bod(y)` (PIAN point localization).
-* **Links:** `Odkaz do Digiarchivu` (Direct URL to the DigiArchive record).
+> ⚠ *PIAN – přesnost* is the one filter that is **pre-selected**. For
+> Fieldwork events and Sites the dialog starts with *odchylka jednotky metrů*,
+> *odchylka desítky metrů* and *odchylka stovky metrů* checked, so an
+> otherwise untouched dialog already sends `f_pian_presnost`. Records
+> localised only to a cadastral territory are excluded until you open the
+> picker and add that level yourself.
+
+#### Date ranges
+
+Each date block has a *from* and a *to* picker; an empty picker shows
+*neomezeno* and means an open bound. The API rejects a one-sided range, so the
+plugin substitutes a sentinel (`0001-01-01` / `9999-12-31`) for the empty
+side. A block with **both** pickers empty adds no filter at all.
+
+A reversed range (start later than end) is refused when you confirm the
+dialog — such a query would come back empty and would be indistinguishable
+from a genuinely empty result.
+
+#### Codelists (hesláře)
+
+The controlled vocabularies behind the pickers are cached in
+`amcr_viewer/codelists/heslar.csv` and ship with the plugin. Click
+**Aktualizovat hesláře 🔄** to rebuild the file from the live APIs; it runs as
+a background QGIS task with a progress bar and takes a few minutes.
+
+Most codelists come from the AMČR **OAI-PMH** endpoint. Two are built from
+Digiarchiv **search facets** instead, because they are lists of people rather
+than a published vocabulary: *Vedoucí výzkumu* (`f_vedouci`, faceted over
+fieldwork events) and *Nálezce* (`f_nalezce`, faceted over individual finds).
+
+#### Components
+
+Check **Načíst komponenty** (Events and Sites only) to bring the period and
+activity area of each component into the output layer.
+
+> ⚠ With components loaded, spatial features are **duplicated** — one feature
+> per component. Areas and feature counts computed on such a layer are
+> misleading.
+
+Note that *Období* and *Areál* also act as component filters even when the
+box is unchecked: a documentation unit whose components match nothing is
+dropped from the result.
+
+### 3.4 Output layers
+
+Up to three temporary `memory` layers are created per download, in **S-JTSK
+(EPSG:5514)**:
+
+* `AMCR_Akce_Body` / `_Linie` / `_Polygony`
+* `AMCR_Lokalita_Body` / `_Linie` / `_Polygony`
+* `AMCR_Samostatný_nález_Body` / `_Linie` / `_Polygony`
+
+A layer is only created if the query actually returned that geometry type.
+All layers of one download share the same attribute schema. Field names are
+ASCII; the human-readable names visible in the attribute table are QGIS field
+aliases.
+
+> Memory layers are **not persistent** — export them (GeoPackage, Shapefile,
+> …) before closing the project.
+
+Geometry is taken from the record's S-JTSK WKT when present; otherwise the
+WGS-84 fallback is reprojected. Invalid geometries are repaired rather than
+dropped.
+
+The tables below group the fields by meaning. In the layer they appear in the
+order *common → entity-specific → `pristupnost` → component fields*.

+
+### 3.5 When a query returns nothing
+
+Progress and errors are written to the QGIS *Messages* panel, tab **AMČR**
+(login goes to **AMČR login**). The log contains the **exact request URL**,
+so a suspicious query can be replayed in a browser instead of being
+reconstructed from the code. Distinct messages tell apart an empty result, an
+API error, a network failure and a result without any geometry.
+
+Only one download can run at a time; starting a second one while the first is
+still running is refused with a message.
+

-## 4. Technical Architecture
+## 4. Technical notes
 
-The plugin is developed in **Python 3** using the **PyQt5** framework for the GUI and the **Requests** library for HTTP communication.
+The plugin is plain **Python 3** with **`requests`** for HTTP. The GUI is
+built through the **`qgis.PyQt`** compatibility layer rather than importing
+`PyQt5`/`PyQt6` directly, which is what lets a single source tree run on both
+QGIS 3.44 (Qt 5) and QGIS 4 (Qt 6). Every enum is referenced in its scoped
+form (`Qt.CheckState.Checked`, …), as required by Qt 6.
 
-### 4.1 File Structure
+### 4.1 Repository layout
 
-* `amcr_viewer.py`: Entry point; handles GUI integration and initialization.
-* `amcr_dialog.py`: Manages the UI logic, including the custom `FilterableSelectionDialog` for handling large vocabularies.
-* `amcr_tools.py`: Core logic module. Handles API requests, pagination, data parsing, and vector layer generation.
-* `amcr_codelists.py`: Manages local caching of controlled vocabularies (`codelists/*.csv`).

-### 4.2 Data Flow & API Integration
+### 4.2 API endpoints
 
-The plugin interacts with three primary endpoints of the AIS CR infrastructure:
+| Purpose | Endpoint | Notes |
+| --- | --- | --- |
+| Login | `POST https://digiarchiv.aiscr.cz/api/user/login` | Returns a session cookie. Errors arrive with HTTP 200 and an `error` key. |
+| Search | `GET https://digiarchiv.aiscr.cz/api/search/query` | `entity=akce\|lokalita\|samostatny_nalez\|pian`, `mapa=true`, paginated. |
+| Translations | `GET https://digiarchiv.aiscr.cz/api/assets/i18n/cs.json` | Code → Czech label; cached in memory for the session. |
+| Codelists | `GET https://api.aiscr.cz/2.2/oai` | OAI-PMH `ListRecords`, with resumption tokens. |
 
-1. **Search API (Solr):**
-* Endpoint: `https://digiarchiv.aiscr.cz/api/search/query`
-* Method: `GET`
-* Parameters: `entity=akce`, `fl` (field list), `q` (query), `rows/page` (pagination).
-* Logic: The plugin implements a `while True` loop to handle pagination, processing data in batches of 500 records to ensure stability.
+### 4.3 Processing pipeline
 
+1. **Metadata** are paged in batches of **500** records, deduplicated by
+   `ident_cely`, until the reported `numFound` is reached or the cap is hit.
+2. Records **without geometry are skipped**; the rest are expanded into
+   documentation units and — if requested — into components.
+3. **Geometries** (PIAN) are fetched separately in batches of **200**
+   identifiers, to stay under URL length limits.
+4. Features are built, reprojected to EPSG:5514, sorted by geometry type and
+   added to the project in a single batch per layer.
 
-2. **Translation API:**
-* Endpoint: `https://digiarchiv.aiscr.cz/api/assets/i18n/cs.json`
-* Function: Retrieves the mapping between system codes (e.g., `HES-xxxx`) and Czech labels. This dictionary is cached in memory during the session.
+### 4.4 Data persistence
 
+* **Codelists** — `amcr_viewer/codelists/heslar.csv`, rewritten only when the
+  user asks for an update.
+* **Credentials** — QGIS Authentication Manager; the config ID is kept in
+  `QSettings` under `amcr_viewer/auth_config_id`.
+* **Layers** — `memory` only, lost when QGIS closes.
 
-### 4.3 Data Persistence
+### 4.5 Limits
 
-* **Vocabularies:** Static vocabularies (e.g., Periods, Regions) are stored in `codelists/heslar.csv`.
-* **Dynamic Data:** The list of investigators is downloaded on-demand and cached in `codelists/vedouci.csv`.
-* **Layers:** Output layers are created as `memory` layers. They are non-persistent and will be lost if QGIS is closed without saving.
+* **20 000 records** per query (safety cap; QGIS would otherwise freeze).
+* **500** records per metadata request, **200** identifiers per geometry
+  request.
+* With components loaded, one output feature equals one component, so a
+  single PIAN can appear several times in the layer.
 
-### 4.4 Constraints
+---
 
-* **Record Limit:** A safety cap of 20,000 records is enforced to prevent memory overflow in QGIS.
-* **Batch Processing:** Geometry fetching is batched (50 IDs per request) to comply with URL length limitations and server load balancing.
+## 5. Development
+
+Contributor rules, branch naming and the manual QGIS test checklist live in
+[`AGENTS.md`](./AGENTS.md).
+
+Every pull request runs
+[`.github/workflows/code_quality.yml`](.github/workflows/code_quality.yml),
+which mirrors what plugins.qgis.org checks on upload and adds what it does
+not:
+
+| Job | What it does |
+| --- | --- |
+| **Lint a bezpečnost** | `tests/check_sources.py`, bandit, detect-secrets, flake8, ruff |
+| **Kompatibilita s Qt6** | `pyqgis4-checker` in dry-run mode |
+| **Smoke test** | loads the plugin in headless QGIS — both `ltr` (Qt 5) and `stable` (Qt 6) |
+| **Balíček pluginu** | builds `amcr_viewer.zip`, asserts its contents, uploads it as an artifact |
+
+Reproducing them locally:
+
+```bash
+python3 tests/check_sources.py
+ruff check .
+flake8 --isolated amcr_viewer/
+bandit -r amcr_viewer/
+docker run --rm -v "$PWD:/work:ro" -w /work --user "$(id -u):$(id -g)" \
+  -e HOME=/tmp qgis/qgis:stable python3 tests/smoke_test.py

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+  Plný seznam změn v češtině je dostupný zde: https://github.com/ARUP-CAS/aiscr-qgis-amcr-viewer/releases/tag/v2.1.1
+  v2.1.4 (2026-10-01)
+   * Removed unused generated resources.py and the bundled flake8 config, so the plugin passes the plugins.qgis.org scan without custom configuration
+  v2.1.3 (2026-10-01)
+   * Fixed empty person codelists (excavation leaders, finders) after updating codelists against Digiarchive v4.1.0
+   * A codelist that fails to download keeps its previous values and the user is warned
+  v2.1.2 (2026-09-01)
+   * Qt6 compatibility
+   * Code clean-up
+  v2.1.1 (2026-09-01)
+   * Added download of Individual finds (PAS), including a dedicated menu entry
+   * Added filtering by date
+   * Added filtering of project fieldwork events and a Project column in the attribute table
+   * Codelists are now built from the Digiarchiv API as well, not only from OAI-PMH; persons come from its facets by role (finder, fieldwork leader)
+   * Updated the bundled codelist file
+   * Filter dialog is now scrollable
+   * Empty API results are now diagnosable from the Messages panel: the query URL and API errors are logged
+   * Code clean-up
+  v2.0.2 (2026-06-13)
+   * Plugin-wide fixes and optimalizations (details https://github.com/ARUP-CAS/aiscr-qgis-amcr-viewer/pull/49)
+  v2.0.1 (2026-06-10)
+   * Fixed QGIS minimum version
+  v2.0.0 (2026-06-05)
+   * Added warning regarding the feature duplication when loading components to the dialog 
+   * Added Help button to the plugin menu
+   * Code clean-up
+  v2.0.0-alpha.4 (2026-06-03)
+   * Backend filtering of the results based on the component-related filters improvement (plugin not only loads the results from API, it filters them further)
+  v2.0.0-alpha.2–3 (2026-05-19)
+   * Security vulnerabilities fix
+  v2.0.0-alpha.1 (2026-05-19):
+   * Attribute fields renamed to be ASCII compliant
+   * Codelist update; codelist can be recompiled from AMČR API
+   * Base element changed from Documentation Unit to Component if user asks for components to simplify result filtering
+   * Plugin now supports logging with an AMČR account and enables the downloading of Events and Sites available to the roles Researcher and higher
