david-spacilandClaude Sonnet 5 222fe03bb8 ci: kontrola bumpu verze a changelogu při PR z version/* do main
Nová kontrola v release_pr_checks.yml ověří na PR směřujícím do main,
že verze v metadata.txt šla nahoru, první položka changelogu patří
nové verzi, CITATION.cff má stejnou verzi a posunuté date-released,
a že název release větve (version/vX.Y.Z) odpovídá verzi v metadata.txt.

david-spacil 49fbd91cea feat: přidáno pole s váhou prvku
v případě možnosti stahování komponent bylo přidáno do tabulek s geometrií pole
`Váha prvku`, vypočtené jako 1/*n*, kde *n* představuje počet komponent na jednu
dokumentační jednotku. Změna by měla být užitečná v případě počítání heatmap.

david-spacilandClaude Opus 5 62d9ebd6f0 feat: verze 2.2.0 — sjednocení popisků filtrů (#64)
* fix: sjednocení popisků filtrů ve filtračním dialogu

Dvě nekonzistence, které vyplavalo psaní dokumentace:

- "Lokalita - stav dochování" mělo jako jediné ze čtyř polí lokality
  obyčejný spojovník místo pomlčky.
- Filtr "Specifikace nálezu" plní sloupec, jehož alias je "Materiál",
  takže uživatel filtroval podle jednoho názvu a výsledek dostal pod
  jiným. Sjednoceno na "Materiál". Klíč v cache (specifikace)
  i parametr API (f_specifikace) zůstávají beze změny, mění se jen
  popisek v UI.

Matice filtrů v README je srovnaná ve stejném commitu, aby se
dokumentace a kód nikdy nerozešly.

Ověřeno výpisem group boxů z dialogu v headless QGIS 4.2.2.

* chore: verze 2.2.0 a changelog

Odkaz "Plný seznam změn" mířil na tag v2.1.1, přestože changelog
pokračuje dál; přesměrován na přehled releasů. Vratná změna.

CITATION.cff zůstává na v2.1.2 — popisuje poslední vydanou verzi
a povyšuje se až při vydání, kdy z něj Zenodo generuje záznam.

Datum 2026-09-02 je datum přípravy; při vydání ho může být potřeba
posunout.

david-spacil 06036f2af0 Merge pull request #63 from ARUP-CAS/agents/claude/readme
docs: README podle aktuálního stavu kódu
2026-09-02 10:16:36 +02:00
david-spacilandClaude Opus 5 8fa81394f2 docs: README podle aktuálního stavu kódu
README popisovalo stav před v2.1.1 a chyběla v něm celá jedna entita.

- Doplněny samostatné nálezy (PAS) včetně vlastní atributové tabulky,
  filtry podle data a "Pouze projektové akce".
- Filtry rozepsány do matice dostupnosti podle entity — dosud byly
  uvedené jako jeden společný seznam, což neplatí ani pro Organizaci,
  ani pro PIAN – přesnost a Areál.
- Doplněno CRS výstupních vrstev (EPSG:5514), které chybělo úplně.
- Doplněno, že hesláře vznikají i z facet Digiarchivu (f_vedouci,
  f_nalezce), nejen z OAI-PMH.
- Upozornění, že PIAN – přesnost je jediný předvyplněný filtr, takže
  nedotčený dialog už záznamy lokalizované katastrem vynechává.
- Opraveno tvrzení "developed using the PyQt6 framework": kód importuje
  přes qgis.PyQt, což je právě důvod, proč běží na Qt5 i Qt6.
- Nová sekce Development s tabulkou CI jobů a příkazy pro lokální běh.

Popisky filtrů odpovídají stavu na main. Jejich sjednocení ("Materiál",
pomlčka u stavu dochování) jde samostatně do version/v2.2.0, takže se
dokumentace nedostane před kód.

Anglická terminologie převzata ze slovníku Digiarchivu
(api/assets/i18n/en.json), ne z nápovědy — ta o PAS ani datových
filtrech nic neví. Matice filtrů ověřena výpisem dialogu v headless
QGIS, názvy polí a aliasy porovnány skriptem proti amcr_tools.py
(43 názvů a 43 aliasů, všechny doslova sedí).

**Platform:** QGIS 3.44.0–4.99.0
**AMČR Viewer** queries the Digital Archive of the Archaeological Map of the
Czech Republic (AMČR) and turns the result into ordinary QGIS vector layers.
It removes the manual export/import round trip: you filter the archive from
inside QGIS and the matching records arrive as point, line and polygon layers
with a full attribute table.
**Module Type:** Data Acquisition & Visualization
**Source Data:** Archaeological Map of the Czech Republic (AIS CR)
| | |
| --- | --- |
| **Source data** | [Digital Archive AMČR](https://digiarchiv.aiscr.cz/) (AIS CR) |
| **Supported QGIS** | 3.44.0 – 4.99.0 (Qt 5 and Qt 6) |
| **Output** | temporary `memory` layers, S-JTSK / **EPSG:5514** |
| **Access** | anonymous by default; optional login for non-public records |
| **UI language** | Czech |
| **Licence** | GPL-3.0 |

## 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* and *Sites* data (metadata and geometry) directly within the GIS environment**, eliminating the need to manually export data from the web interface. Both *Fieldwork events* and *Sites* layers may optionally include component-level data (period and activity area) embedded directly in the attribute table. The plugin supports both **anonymous (public) access** and **authenticated access** for users with an AMČR account.
The plugin covers three AMČR record types. Each has its own menu entry, its
own set of filters and its own attribute table.
### Key Features
| 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. |
* **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.
* **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.
* **Authenticated Access:** Users with an AMČR account can log in to access non-public records.
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.
## 2. Installation Guide
### Key features
**Install the latest version of the plugin from the QGIS plugin repository.**
* **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.
**OR** (*in case you need older version*)
---
1. *Obtain the [plugin distribution package](https://github.com/ARUP-CAS/aiscr-qgis-amcr-viewer/releases) (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 Viewer button will appear in the toolbar.*
## 2. Installation
## 3. User Manual
### From the QGIS plugin repository (recommended)
### 3.1 Authentication (Optional)
*Plugins → Manage and Install Plugins… → search for* **AMČR Viewer** *→
Install*.
By default, the plugin accesses only publicly available records (accessibility = anonymous). To access non-public data, log in using your AMČR account:
### From a ZIP archive (older versions, or a build from source)
* Click the dropdown arrow on the AMCR Viewer toolbar button and select **Přihlásit se**.
* Enter your e-mail and password. Credentials are encrypted and stored securely in the **QGIS Authentication Manager** (DPAPI on Windows, Keychain on macOS, encrypted SQLite on Linux).
* Stored credentials are reused automatically across sessions. To update or remove them, open the login dialog again.
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*.
### 3.2 Data Retrieval
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.
To initiate a search query, click either the **Stáhnout data akcí** or the **Stáhnout data lokalit** option from the dropdown menu. The filter dialog provides the following options. Shown options vary based on the chosen tool.
After installation the **AMČR Viewer** button appears in the toolbar as a
dropdown.
* **Spatial Filter:** *Checkbox "Omezit vyhledávání rozsahem okna":* 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).
* **Positive findings only:** If checked, only *PIANs* belonging to Documentation units marked as "Type of evidence" = "positive" are included. *(Fieldwork events only.)*
### Requirements
* **Attribute Filters:**
* The dialog uses "Picker" widgets for controlled vocabularies (common: Region, District, Cadastral area, Period, Activity Area, *PIAN* accuracy, Accessibility; *events* related: Organisation, Researcher, Event type; *sites* related: Site type and class, Level of confidence, State of preservation).
* Click **Vybrat...** to open a searchable selection window. Multiple values can be selected simultaneously (Logic: OR).
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`).
* **Codelists (Hesláře):**
* Controlled vocabularies are downloaded from the AMČR OAI-PMH API and cached locally in `codelists/heslar.csv`.
* To refresh all codelists, click the **Aktualizovat hesláře 🔄** button in the filter dialog. This runs as a background task and may take a few minutes.
---
* **Components:** Check **Načíst komponenty** to include period and activity area data directly in the output layers.
> ⚠ When components are loaded, spatial features are duplicated — each feature corresponds to one component. Spatial analyses (areas, counts) may be inaccurate.
## 3. User manual
* If no filter is used, all accessible Fieldwork events/PIANs are returned (the number of records is capped at 20 000; it is advisable to set at least one filter).
### 3.1 Toolbar and menu
For a more in-depth tutorial refer to the [AMČR Documentation](https://amcr-help.aiscr.cz/digiarchiv/qgis-viewer.html) (only in Czech).
The toolbar button is a dropdown; the default action is *Stáhnout data akcí*.
### 3.3 Layer Structure & Attributes
Upon successful retrieval, the plugin generates up to three temporary memory layers:
1. **AMCR\_[Akce|Lokalita]\_Polygony**
2. **AMCR\_[Akce|Lokalita]\_Linie**
3. **AMCR\_[Akce|Lokalita]\_Body**
Layers are only created if the query returns features of the corresponding geometry type. All layers share the same attribute schema.
#### 3.3.1 Common fields
| Field | Description |
| Menu entry | Action |
| --- | --- |
| pian | PIAN (spatial identifier) ID |
| presnost | Spatial deviation \[units/tens/hundreds of meters/defined by cadastre\] |
| pian\_typ | \[point/line/polygon\] |
| dj | Documentation unit ID |
| typ\_dj | \[trench/event part/whole event/cadastral territory\] |
| definicni\_body | Feature centroid in WGS-84 coordinate system |
| akce / lokalita | Fieldwork event / Site ID |
| odkaz\_do\_digiarchivu | Link to the record in the Digital Archive |
| okres | District |
| katastr | Main cadastral area |
| dalsi\_katastry | Other cadastral areas, if the event extends beyond the main cadastre |
| Přístupnost | Record accessibility \[A/B/C/D\] |
| *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. |
#### 3.3.2 Fields related to *Fieldwork events*
### 3.2 Authentication (optional)
| Field | Description |
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*).
### 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.

#### Spatial restriction
*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).
#### PIAN accuracy has a non-empty default
> ⚠ *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.
For a step-by-step tutorial see the
[AMČR documentation](https://amcr-help.aiscr.cz/digiarchiv/qgis-viewer.html)
(Czech only).

## 4. Technical notes
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 Repository layout

### 4.2 API endpoints
| 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. |
### 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.
### 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.
### 4.5 Limits
* **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.

## 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 |
| --- | --- |
| akce\_lokalizace | Verbal description of the event location |
| vedouci | Main fieldwork manager |
| organizace | Organisation conducting the research |
| specifikace\_data | \[exact date/exact years/sometime in years\] |
| zahajeni | Event start date |
| ukonceni | Event end date |
| hlavni\_typ | Primary research method |
| vedlejsi\_typ | Secondary research method |
| zjisteni | Did the research reveal archaeological contexts? \[positive/negative\] |
| nahrazuje\_NZ | Replaces a fieldwork report? \[yes/no\] |
| **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 |
#### 3.3.3 Fields related to *Sites*
Reproducing them locally:
| Field | Description |
| --- | --- |
| nazev\_lokality | Site name |
| popis\_lokality | Site description |
| typ\_lokality | Site classification by definition method |
| druh\_lokality | Site classification by the nature of identified field relics |
| zachovalost | Site preservation state |
```bash
python3 tests/check_sources.py
ruff check .
flake8 --config amcr_viewer/.flake8 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
```
#### 3.3.4 Component fields (only when *Načíst komponenty* is checked)
---
| Field | Description |
| --- | --- |
| komponenta | Component ID |
| komponenta\_areal | Activity area \[settlement/burial area/field/…\] |
| komponenta\_obdobi | Period \[Neolithic/High Middle Ages–Modern Period/…\] |

(Czech only; describes v1.3.2)
The plugin is developed in **Python 3** using the **PyQt6** framework for the GUI and the **Requests** library for HTTP communication.
## Citing
> **Note:** The `requests` library is bundled with the QGIS installers for Windows and macOS. On Linux (distribution packages), it may need to be installed separately (e.g. `python3-requests`).
Cite the plugin using [`CITATION.cff`](./CITATION.cff) or the concept DOI
[10.5281/zenodo.18609813](https://doi.org/10.5281/zenodo.18609813), which
always resolves to the latest release.
### 4.1 File Structure
## Licence
* `amcr_viewer.py`: Entry point; handles GUI integration, toolbar/menu setup, and login flow.
* `amcr_dialog.py`: Manages the UI logic, including `AmcrFilterDialog`, `FilterableSelectionDialog`, and `LoginDialog`.
* `amcr_tools.py`: Core logic module. Handles authentication, API requests, pagination, data parsing, and vector layer generation.
* `amcr_codelists.py`: Manages local caching of controlled vocabularies (`codelists/heslar.csv`) downloaded via OAI-PMH.
### 4.2 Data Flow & API Integration
The plugin interacts with the following endpoints:
1. **Login API:**
* Endpoint: `https://digiarchiv.aiscr.cz/api/user/login`
* Method: `POST`
* Returns a session cookie used for subsequent authenticated requests.
* Credentials are stored in the QGIS Authentication Manager; the session is restored automatically if it expires mid-download.
2. **Search API (Solr):**
* Endpoint: `https://digiarchiv.aiscr.cz/api/search/query`
* Method: `GET`
* Parameters: `entity=akce|lokalita|pian`, `rows/page` (pagination), `mapa=true`.
* Logic: Paginated in batches of 500 records (metadata) and 200 records (geometries). A safety cap of 20 000 records is enforced.
3. **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. Cached in memory for the session.
4. **Codelists API (OAI-PMH):**
* Endpoint: `https://api.aiscr.cz/2.2/oai`
* Used for downloading controlled vocabularies (periods, regions, organisations, etc.) on demand.
### 4.3 Data Persistence
* **Vocabularies:** Stored in `codelists/heslar.csv`; updated on user request via the background task.
* **Layers:** Output layers are created as `memory` layers. They are non-persistent and will be lost if QGIS is closed without saving.
### 4.4 Constraints
* **Record Limit:** A safety cap of 20 000 records is enforced.
* **Batch Processing:** Geometry fetching is batched (200 IDs per request) to comply with URL length limitations and server load balancing.
* **Component duplication:** When components are loaded, each output feature corresponds to one component rather than one documentation unit. A single PIAN may therefore appear multiple times in the layer.

"""
Guards the release PR (version/vX.Y.Z -> main).
Checks that the version actually moved forward and that the three places
that name it agree, because plugins.qgis.org and Zenodo both read from
files a human has to remember to touch by hand:
* amcr_viewer/metadata.txt: version= must be higher than on main, and the
first changelog entry must be for that exact version
* CITATION.cff: version must match metadata.txt, and date-released must
not be left pointing at the old release
* the branch name (version/vX.Y.Z) must match metadata.txt, so a stray
push to the wrong release branch is caught before merge
