 # Changelog
 All notable changes of the flash card program. The format follows
 [Keep a Changelog](https://keepachangelog.com/en/1.1.0/); the version follows
 [Semantic Versioning](https://semver.org/).
 ## [0.2.0] - 2026-10-15
 Adds the classic menu bar and keeps the progress of each word list apart.
 ### Added
 - A menu bar. File: Open... (another word list from a CSV file with a header
  of two language codes), Change level... (the level choice without a restart),
  Reset word list... (after a confirmation the progress of the open list is
  removed and all its words are to learn again), Exit. About: Contact (the
  author's name and title, and a link to the author's LinkedIn page).
 - The progress of each word list is a file of its own: `words_to_learn.csv` for
  `ms-da.csv` (unchanged) and `words_to_learn_<name>.csv` for another list.
 ### Fixed
 - A word list that is not UTF-8 text gives a message that names the file,
  instead of an error.
 - The level screen has the same window title, padding and background as the
  card screen.
 ### Known limits
 - The executable is not signed; Windows SmartScreen may warn about it.
 - The executable is not attached to the release: the upload limit of the git
  host rejects a file of its size (HTTP 413, already at 1 MB). Build it with
  `python tools/build_executable.py`.
 - An opened word list is not remembered after a restart.
 ## [0.1.0] - 2026-10-15
 First release. The solution of day 31 of Udemy's *100 Days of Code: The Complete
 Python Pro Bootcamp*, for Malay words with Danish translations.
 ### Added
 - The four assignment steps: the window with a card and two buttons, a random
  card on every press, the flip to the translation after 3 seconds, and the
  progress file `data/words_to_learn.csv`.
 - A choice of level before learning: the first 100 words, the first 1000 words
  or all words of the frequency ordered word list; `--level 100|1000|all`.
 - The spoken Malay word through the optional extra `speech` (gTTS and
  playsound); `--no-speech`.
 - A single Windows executable built with PyInstaller (`python
  tools/build_executable.py`); the progress is kept in a `data/` folder next to
  it, and a `data/ms-da.csv` next to it replaces the word list inside it.
 - README, a wiki in English, Danish and Bahasa Malaysia, and Doxygen comments.
 ### Known limits
 - The executable is not signed; Windows SmartScreen may warn about it.
 - The executable is not attached to the release: the upload limit of the server rejects a file of its size. Build it with `python tools/build_executable.py`.
 - The executable is built for Windows (x64); on Linux and macOS run the program
  from source or build it on that system.
 - The Danish column of the word list is machine translated.

A known word is removed from the words to learn, and the words still to learn are saved, so the next start continues where you stopped.

 ### Executable (Windows, no Python needed to run it)
 The release pages of [v0.2.0][release-0-2-0] and [v0.1.0][release-0-1-0] have the release notes. The executable is not attached there yet, because the server's upload limit rejects a file of this size (HTTP 413). Build it yourself:
 ```powershell
 python -m pip install -e ".[build,speech]"
 python tools/build_executable.py
 ```
 The script builds `dist/flash-card.exe`: one file, no console window, with the images, the word list and the spoken word inside. Open it by double-clicking. It keeps your progress in a `data/` folder next to the executable (`data/words_to_learn.csv`); a `data/ms-da.csv` next to it replaces the word list inside. Add `--no-speech` to the build script to leave the speech packages out. The executable is a build output and is not committed; build it on the system you want to run it on (Windows, Linux or macOS).

 # ADR-0004: Windows executable built with PyInstaller

 Allowed Status values: `Proposed`, `Accepted`, `Rejected`, `Deprecated`, `Superseded by ADR-NNNN`.
 ---
 ## Context
 The Product Owner (S01) wants an executable file, so that the program can be started without a Python installation (US-001.07). The program has images, a word list, a progress file that must survive restarts, and an optional speech extra. Options:
 1. A one-directory build (a folder with the executable and its libraries): starts faster and the data can sit beside the files, but it is a folder of hundreds of files to hand over.
 2. A one-file build (a single `flash-card.exe` that unpacks itself to a temporary folder): one file to hand over, slower start; resources are in a temporary folder, so progress needs a place beside the executable.
 3. Another packager (Nuitka, cx_Freeze) or an installer: more tooling and a larger change for the same result.
 ## Decision
 Build a one-file, windowed (no console) Windows executable with PyInstaller by `tools/build_executable.py`. The images and the word list are inside the executable. The progress file and an optional word list are in a `data/` folder beside the executable (found with `sys.executable` when `sys.frozen` is set), and `--data-dir` still overrides it. PyInstaller is only in the optional extra `build`, so `dependencies` stays empty (ADR-0001). The executable is a build output and is not committed.
 ## Consequences
 **Positive:**
 - One file to hand over, and no Python, `.venv` or pip needed to run it.
 - The source run is unchanged; only the path rule differs when frozen, and it is tested without PyInstaller.
 - The word list stays editable beside the executable.
 **Negative:**
 - PyInstaller cannot cross-compile: the executable must be built on Windows (and on Linux or macOS for those systems).
 - A one-file executable unpacks to a temporary folder at each start and is larger with the speech packages; unsigned executables can trigger Windows SmartScreen or antivirus warnings.
 - The Windows Store Python can cause Tcl/Tk path problems with PyInstaller; a build with it must be checked by a real start.
 ## Affected Artifacts
 - [BC-001] — scope: the executable is in scope; installer, signing and release upload are out
 - [US-001] — US-001.07 Start without Python
 - [DCD-001] — packaging support and the choice of the word list file in the composition root

 # ADR-0005: Container and sandbox checks without the user's desktop

 ---
 ## Context
 Smoke tests of the program drive a real window. Run on the Product Owner's own Windows desktop they open windows, take the focus and move the mouse, which interrupts the Product Owner's work (RC-072). The checks must run somewhere else. Options:
 1. A Windows hidden desktop (a second Win32 desktop of the same session): invisible, but still the host's session and a place where a mistake can reach the host.
 2. A Debian Docker container with a virtual X screen and GNOME for the Linux checks, and Windows Sandbox for the Windows executable: both are isolated from the host's input and desktop; the Debian check is not a Windows check.
 3. A Wine container for the Windows executable, or a real Windows virtual machine run in Docker with KVM: Wine is an emulation of the Windows interface; the Windows virtual machine needs a Microsoft evaluation image of tens of gigabytes and licence terms the Product Owner has not accepted.
 4. macOS in Docker: not possible on a Windows host, and Apple's licence allows macOS only on Apple hardware.
 ## Decision
 Run the Linux checks (linters, tests including the real window, screenshots, a Linux binary and its smoke test) in a Debian image based on `python:3.13-slim-bookworm` with Xvfb, GNOME's window manager and, if it runs in a container, the GNOME session. Run the Windows executable in Windows Sandbox of Windows 11 Pro through a `.wsb` configuration and a script that presses the known button inside the sandbox and writes the result to a mapped folder. Do not run macOS, and state that in the documents.
 ## Consequences
 **Positive:**
 - No check takes the focus or the mouse of the host any more.
 - The container checks are repeatable on any machine with Docker and need no Python installation.
 - The sandbox is a real Windows, thrown away after each run.
 **Negative:**
 - The Debian image is large (a desktop and a Python image) and the first build takes time.
 - A full GNOME session may not run in a container; the fallback (GNOME's window manager) is a weaker statement, and the record says which one ran.
 - Windows Sandbox needs Windows 11 Pro with the feature enabled and shows its own window on the host while it runs.
 - macOS stays untested.
 ## Affected Artifacts
 - [BC-001] — In Scope and Out of Scope lists
 - [ADR-0004] — the executable that the sandbox runs

- Reading the Malay to Danish list from `data/ms-da.csv` (semicolon separated, header `ms;da`).
+- Python 3.13 or later Tkinter program with the assignment's function names (`next_card`, `flip_card`, `is_known`).
- Saving the words still to learn to `data/words_to_learn.csv` and using that file on the next start.
+- Reading the Malay to Danish list from `data/ms-da.csv` (semicolon separated, header `ms;da`).
- Optional spoken Malay word (text to speech) as an extra that can be installed.
+- Saving the words still to learn to `data/words_to_learn.csv` and using that file on the next start.
- `pyproject.toml`, `.gitignore`, `Doxyfile`, virtual environment instructions, `pytest` tests and `constants.py`.
+- Optional spoken Malay word (text to speech) as an extra that can be installed.
- README from the framework template, screenshots, and a wiki in English, Danish and Bahasa Malaysia.
+- A choice of level (the first 100 words, the first 1000 words or all words of the frequency ordered word list) before learning starts.
- Repository description and topics on the git host.
+- A menu bar with the commands to open another word list (CSV), change the level, reset a word list, exit, and the author's contact.
- The framework documents of the baseline: Business Case, Stakeholder Analysis, Project Plan, milestones, review records and traceability matrix.
+- Checks that do not use the user's desktop: a Debian based Docker image with a virtual GNOME desktop for the tests, headless screenshots and a Linux binary, and Windows Sandbox for the Windows executable.
-
+- A single Windows executable file, built with PyInstaller by a script of this repository, that runs without an installed Python.
-### Out of Scope
+- Tagged releases of the repository (`v0.1.0`, `v0.2.0`), each with release notes and, when the git host accepts the upload, the executable and its SHA-256 checksum attached.
-
+- `pyproject.toml`, `.gitignore`, `Doxyfile`, virtual environment instructions, `pytest` tests and `constants.py`.
- Other languages: the user interface labels are Malay and Danish only; another word list works by changing the data file but is not delivered.
+- README from the framework template, screenshots, and a wiki in English, Danish and Bahasa Malaysia.
- Spaced repetition scheduling, statistics, accounts, cloud synchronisation and mobile apps.
+- Repository description and topics on the git host.
- Packaging for distribution on PyPI or as an installer.
+- The framework documents of the baseline: Business Case, Stakeholder Analysis, Project Plan, milestones, review records and traceability matrix.
- Redistribution of the course's own image files; the card and button images are generated for this project.
+
- A translation quality review of the word list.

+## Purpose and Scope
-The design classes of the program in `src/flash_card/`, in four layers (domain, application, infrastructure, presentation) with the presentation pattern MVVM ([ADR-0002]). The classes refine the concepts of [DM-001]; names are the IT terms of [DICT-001]. Methods trace to the operation contracts of [OC-001] and the sequence diagrams of [SD-001] (the SSD messages are in [SSD-001]).

+The design classes of the program in `src/flash_card/`, in four layers (domain, application, infrastructure, presentation) with the presentation pattern MVVM ([ADR-0002]). The classes refine the concepts of [DM-001]; names are the IT terms of [DICT-001]. Methods trace to the operation contracts of [OC-001] and the sequence diagrams of [SD-001] (the SSD messages are in [SSD-001]). The module `flash_card/runtime.py` (where the resources and the data folder are when the program is frozen by PyInstaller) and the scripts in `tools/` are packaging support ([ADR-0004]): they have no system operation and are not design classes; `app.main` is still the only place that names the adapters, and it chooses the word list file.

 ## Pattern Annotations
 | Pattern | Classes | Rationale |
 | --- | --- | --- |
 | Repository | `VocabularyRepository`, `ProgressRepository`, CSV adapters | The domain does not know the CSV file |
 | Ports and adapters | `SpeechPort`, `GttsSpeech`, `NullSpeech` | Speech is an optional extra; the core runs without it |
 | Null Object | `NullSpeech` | No `if speech:` checks in the use case |
 | MVVM | `FlashCardView`, `FlashCardViewModel`, `LevelView`, `LevelViewModel`, `MenuView`, `MenuViewModel` | Behaviour is tested without Tkinter ([ADR-0002]) |
 | Composition root | `app.main` | The one place that names the adapters, shows the level screen and chooses the word list file (beside the executable, else inside it) |
 | Controller (GRASP) | `Application` | One object receives the menu and level commands and coordinates repositories and sessions |
 | Value object | `Level`, `Card`, `LanguagePair` | Immutable data with its own rule (`Level.first`) |
 ## Dependency Check
 Imports point inward: `domain` imports nothing from the other packages; `application` imports `domain`; `infrastructure` imports `application` and `domain`; `presentation` imports `application` and `domain`, and `app.main` additionally imports `infrastructure`. There is no cycle. `constants.py` imports nothing from the packages.

 ## Purpose
 Decide whether the Learner can choose a level before learning: the program asks for 100 words, 1000 words or all words, and then uses the first N words of the word list, which is ordered from the most to the least frequent word.
 ## Deliverable
 At start the window shows the choice "100 words", "1000 words" and "All words". After a choice the card window of the earlier milestones opens and every card comes from the first N words of the word list that the Learner does not yet know. Known words stay known across levels because there is still one progress file. The design documents, README, wiki (English, Danish, Bahasa Malaysia) and screenshots describe the choice.
 ## Go / No-Go Criteria
 | # | Criterion (objectively checkable) | Go | No-Go |
 | --- | --- | --- | --- |
 | 1 | Choosing 100 draws only cards that are among the first 100 rows of `data/ms-da.csv`, for every card of a full run through the deck | Integration test passes on the real word list | A card from row 101 or later appears |
 | 2 | Choosing 1000 words or All words uses every word of the list; with a list of fewer than N words all are used | Unit and integration tests pass | Any word is missing |
 | 3 | Marking words known at level 100 and then choosing All words leaves those words known, and `words_to_learn.csv` still holds every word that is not known (also those outside level 100) | Integration test passes | A word outside the level is lost from the file |
 | 4 | When every word of the chosen level is known the card shows the message that nothing is left to learn, and the program does not fail | Unit and e2e tests pass | Exception or empty window |
 | 5 | The level screen holds no rule: the labels and the choice come from the level view model, which imports no Tkinter | View model unit tests pass | A rule is in the view |
 | 6 | `python -m flash_card --level 100` (also `1000`, `all`) skips the screen and starts at that level; an unknown value is refused by the argument parser | Unit tests pass | The screen appears or the program starts |
 | 7 | The updated UC-001, DM-001, DICT-001, SSD-001, OC-001, SD-001, DCD-001, BC-001, wireframe, README and the wiki in three languages mention the level choice, and each changed document has a new Version History row and a `Go` review | Review records `Go`; `check-readme.sh` exit 0 | A document is not updated |
 | 8 | Code review against QC-PY-001 has no failed Mandatory criterion; `pytest` exits with 0 and `ruff`, `mypy --strict`, `lint-imports` and `doxygen` are clean | `RC-*` verdict Go and exit codes 0 | Otherwise |

 ## Tasks
 | # | Task | Summary | Needs its own Use Case/User Story? | Reference |
 | --- | --- | --- | --- | --- |
 | 1 | Update the design documents for the level choice | Add the level to UC-001 (a first step before the cards, and the finished-level extension), to DM-001 and DICT-001 (concept Level), to SSD-001, OC-001 and SD-001 (operation chooseLevel and the level in startStudySession) and to DCD-001; draw the wireframe of the level screen in wireframe.md; add the level choice to the In Scope list of BC-001. Every changed document gets a Version History row and a new review. | No | UC-001, DCD-001 |
 | 2 | Add the Level value object and the level choices | `Level` (limit as a number of words, or none for all words) in the domain and the three choices 100, 1000 and all words in constants.py with their labels, so that the choices are defined once. | No | DCD-001 |
 | 3 | Draw cards from the chosen level | `StudySession` draws only from the first N words of the word list that are still to learn, and removes a known card from the whole words to learn and saves the whole deck, so that words of other levels are never lost. | Yes | US-001.06 |
 | 4 | Open the session with a level | `open_study_session` gets the level, loads the word list for its order and the progress file for what is left, and builds the session; a level with nothing left gives a finished session. | Yes | US-001.06 |
 | 5 | Add the level screen | `LevelViewModel` (the choices and their labels, no Tkinter) and `LevelView` in `presentation/features/level/` with the title "Choose your level" and three buttons on the window background. | Yes | US-001.06 |
 | 6 | Show the level screen before the cards | The composition root shows the level screen first and builds the card view on the same window after the choice; the option `--level 100`, `--level 1000` or `--level all` skips the screen. | Yes | US-001.06 |
 | 7 | Test the level choice | Unit tests of the level, the filter, the session and the view model; integration tests on the real word list and the progress file across levels; e2e test of the level screen and the flow to the first card. | No | |
 | 8 | Update the README, the wiki and the screenshots | README, Usage and Home pages of the wiki in English, Danish and Bahasa Malaysia, and a new screenshot of the level screen made by tools/capture_screenshots.py; republish the wiki after the merge. | No | |

 | 2026-10-15 | Accepted | Jens Tirsvad Nielsen | AI as stand-in for S01 | Added task 9 (fix a flaky unit test found after the merge) | [061b4f4] |
 ---
 ## Purpose
 Decide whether the Learner can start the program from one executable file without a Python installation: the program is packaged with PyInstaller by a script of this repository, and behaves in the executable as it does from the source.
 ## Deliverable
 `python tools/build_executable.py` builds `dist/flash-card.exe` (one file, no console window, an icon, the images and the word list inside, the speech extra included). The executable shows the level screen, keeps the progress in `data/words_to_learn.csv` next to it and prefers a `data/ms-da.csv` next to it over the word list inside. The executable itself is not committed to git; README and wiki (English, Danish, Bahasa Malaysia) explain how to build and use it.
 ## Go / No-Go Criteria
 | # | Criterion (objectively checkable) | Go | No-Go |
 | --- | --- | --- | --- |
 | 1 | `python tools/build_executable.py` ends with exit code 0 and produces `dist/flash-card.exe` | File exists and is larger than 1 MB | No file or a build error |
 | 2 | The executable starts on this machine with the virtual environment not activated and shows the level screen without a console window | A window titled "Flashy" exists after 5 seconds and the process is a Windows GUI program | The process ends or shows a console |
 | 3 | With a `data/ms-da.csv` copied next to the executable it uses that file; without it the word list inside the executable is used | Smoke test with a marked list of two words, then without | The wrong list is used |
 | 4 | Marking a word known in the executable writes `data/words_to_learn.csv` next to it and the next start continues from it | Smoke test reads the file after the run | No file or progress lost |
 | 5 | The four images and the icon are inside the executable and are found when frozen | Card and button images are visible in a captured screenshot of the executable | A missing image or an exception |
 | 6 | Path resolution when frozen (`sys.frozen`, `sys._MEIPASS`) is tested without PyInstaller | Unit tests pass | Not covered |
 | 7 | `dependencies` in `pyproject.toml` is still empty; PyInstaller is only in the extra `build` | File check | A runtime dependency was added |
 | 8 | BC-001, DCD-001 and ADR-0004 are updated and reviewed `Go`; README and wiki in three languages describe the build | Review records `Go`; `check-readme.sh` exit 0 | A document is missing |
 | 9 | Code review against QC-PY-001 has no failed Mandatory criterion; `pytest`, `ruff`, `mypy --strict`, `lint-imports` and `doxygen` are clean | `RC-*` verdict Go and exit codes 0 | Otherwise |

 ## Tasks
 | # | Task | Summary | Needs its own Use Case/User Story? | Reference |
 | --- | --- | --- | --- | --- |
 | 1 | Update the documents for the executable | Amend BC-001 (In Scope: an executable built with PyInstaller; Out of Scope: an installer and a signed release stay out), add ADR-0004 (PyInstaller one-file windowed build, word list inside and a `data` folder beside the executable for progress, Windows only), and add the runtime path resolution to DCD-001. Every changed document gets a Version History row and a review. | No | BC-001, DCD-001 |
 | 2 | Resolve resource and data paths when frozen | The images are found under `sys._MEIPASS` and the default data folder is `data/` next to the executable when `sys.frozen` is set; the source run keeps its paths. The rule is one function used by `constants.py`, tested by simulating the frozen state. | Yes | US-001.07 |
 | 3 | Prefer the word list next to the executable | When the data folder has no `ms-da.csv` the program uses the copy inside the executable; the progress file is always written to the data folder; `--data-dir` still overrides both. | Yes | US-001.07 |
 | 4 | Add the build script and the build extra | `tools/build_executable.py` calls PyInstaller (one file, windowed, name `flash-card`, the assets and the word list as data, the icon, the speech packages as hidden imports); `pyproject.toml` gets the extra `build`; `build/`, `dist/` and `*.spec` are ignored. | No | ADR-0004 |
 | 5 | Generate the application icon | `tools/generate_images.py` also writes `flash_card.ico` (the card with the tick) from the same drawing code, so no external asset is used. | No | |
 | 6 | Build and smoke-test the executable | Build it, start it with the virtual environment not active, check the window, the images, the level choice, the progress file next to it, the word list override and the speech import; record the result in the review record. | Yes | US-001.07 |
 | 7 | Test the path rules and the build arguments | Unit tests for the frozen and source path rules and for the argument list the build script gives PyInstaller (without running PyInstaller). | No | |
 | 8 | Update README and wiki | README and the Install page of the wiki in English, Danish and Bahasa Malaysia: how to build, where the executable and the data folder are, that Python is not needed to run it. The wiki is republished after the merge. | No | |
 | 9 | Fix a flaky unit test | After the merge a unit test of `app.main` failed in about 1 of 6 full runs because it created a real Tk root; it uses the module's fake root instead, so the unit tests never need a display. Found by running the suite repeatedly. | No | RC-049 |

 | 2026-10-15 | Accepted | Jens Tirsvad Nielsen | AI as stand-in for S01 | Initial version | [9c8e294] |
 ---
 ## Purpose
 Decide whether the project can be handed out as a release: the version 0.1.0 is tagged, and the executable built from exactly that commit is attached to a release page with its checksum and release notes.
 ## Deliverable
 A tag `v0.1.0` on the head of `main`, and a release on the git host with the assets `flash-card.exe` and `flash-card.exe.sha256`, and release notes. `CHANGELOG.md` holds the same notes. The README and the wiki (English, Danish, Bahasa Malaysia) link to the release page.
 ## Go / No-Go Criteria
 | # | Criterion (objectively checkable) | Go | No-Go |
 | --- | --- | --- | --- |
 | 1 | The executable is rebuilt from the head of `main` that gets the tag, in a clean build folder, and passes the smoke test of MIL-009 (window, embedded list, progress file beside it, list override) | Smoke test output recorded in the review record | A failing case |
 | 2 | The tag `v0.1.0` is an annotated tag on that commit and `pyproject.toml` and `flash_card.__version__` say `0.1.0` | `git show v0.1.0` and the two files agree | A different version or commit |
 | 3 | The release has the assets `flash-card.exe` and `flash-card.exe.sha256` | Listed by the host API | An asset is missing |
 | 4 | The SHA-256 of the file downloaded from the release equals the value in `flash-card.exe.sha256` and in the release notes | Hash compared after a download | A difference |
 | 5 | The release notes say that the file is an unsigned Windows build, what the `data` folder next to it holds, the SHA-256, and how to build it | Notes read back from the API | A statement is missing |
 | 6 | `CHANGELOG.md`, README and the Install page of the wiki in three languages link the release; `check-readme.sh` exit 0 | Exit code 0 | A link is missing |
 | 7 | BC-001, US-001 and PP-001 are updated (the release upload leaves Out of Scope) and reviewed `Go` | Review records `Go` | A document is not updated |

 ## Tasks
 | # | Task | Summary | Needs its own Use Case/User Story? | Reference |
 | --- | --- | --- | --- | --- |
 | 1 | Update the documents for the release | Amend BC-001 (the upload of the executable to a release leaves Out of Scope and the release becomes In Scope; signing and an installer stay out), add US-001.08 and the gateway to PP-001; each changed document gets a Version History row and a review. | No | BC-001, US-001 |
 | 2 | Write the release notes and CHANGELOG.md | `CHANGELOG.md` (Keep a Changelog layout) with the version 0.1.0: what the program does, the four assignment steps, the level choice, the executable, known limits (unsigned, Windows only, Python 3.13 or later to build); the notes are reused for the release body. | No | |
 | 3 | Rebuild and smoke-test the executable from the tagged commit | Build `dist/flash-card.exe` from a clean tree of the head of `main`, run the smoke test of MIL-009, compute the SHA-256 and write `flash-card.exe.sha256` (not committed). | Yes | US-001.08 |
 | 4 | Tag v0.1.0 | Create an annotated tag `v0.1.0` on the head of `main` and push it; a tag cannot be undone without deleting it on the host, so it is made only after the documents are merged. | No | |
 | 5 | Create the release and attach the files | Create the release `v0.1.0` through the host API with the notes, attach `flash-card.exe` and `flash-card.exe.sha256`, download the asset again and compare the hash. The token is read from `.env` and is never printed or put on a command line. | Yes | US-001.08 |
 | 6 | Link the release | README, the Install page of the wiki in English, Danish and Bahasa Malaysia and `CHANGELOG.md` link the release page; the wiki is republished. | No | |

 ## Purpose
 Decide whether the program has the classic menu bar the Product Owner asked for: a File menu (open a word list, change the level, reset a word list, exit) and an About menu (contact), and whether the commands keep the progress of every word list safe.
 ## Deliverable
 The window has a menu bar. File: Open (a CSV word list), Change level, Reset word list, Exit. About: Contact with the author's name and title and a link to the author's LinkedIn page. The progress of each word list is kept in its own file. README, the Usage page of the wiki in three languages and a screenshot show the menu.
 ## Go / No-Go Criteria
 | # | Criterion (objectively checkable) | Go | No-Go |
 | --- | --- | --- | --- |
 | 1 | The menu bar has File (Open, Change level, Reset word list, separator, Exit) and About (Contact, LinkedIn entry) with the labels of the wireframe | e2e test reads the menu entries and their order | A different structure |
 | 2 | Opening a valid CSV word list switches the cards to it after the level choice; opening an invalid file shows a message and keeps the earlier list; cancelling changes nothing | Unit and e2e tests with a faked file dialog and message box | A wrong list in use or a crash |
 | 3 | The progress of each word list is a file of its own: `words_to_learn.csv` for the delivered `ms-da.csv` and `words_to_learn_<name>.csv` for another list; known words of one list never appear in another | Integration test with two lists | Progress mixed or lost |
 | 4 | Change level shows the level choice again without a restart and keeps the known words | Unit and e2e tests | Restart needed or progress lost |
 | 5 | Reset word list asks to confirm; on yes only the progress file of the open list is deleted and the level choice is shown; on no nothing changes; the word list file is never changed | Unit, integration and e2e tests | Another file touched |
 | 6 | About, Contact opens `https://www.linkedin.com/in/tirsvad74` through `webbrowser` and shows "Jens Tirsvad Nielsen, Software engineer" | Unit test with a faked `webbrowser.open` | Another address |
 | 7 | Exit closes the window, cancels the pending timer and ends the program with exit code 0 | e2e test | A leftover timer or an error |
 | 8 | The menu logic is in a view model without Tkinter; the commands are one use case or application call each | View model unit tests without a display | A rule in the view |
 | 9 | The documents of the plan (BC-001, US-001, UC-001, SSD-001, OC-001, SD-001, DCD-001, DICT-001, wireframe, PP-001) and README and wiki in three languages describe the menu, each reviewed `Go` | Review records `Go`; `check-readme.sh` exit 0 | A document is missing |
 | 10 | Code review against QC-PY-001 has no failed Mandatory criterion; `pytest`, `ruff`, `mypy --strict`, `lint-imports` and `doxygen` are clean | `RC-*` verdict Go and exit codes 0 | Otherwise |
 ## Dependencies

 | 1 | Update the documents for the menu bar | Amend BC-001 (In Scope: a menu bar with the commands), UC-001 (the menu commands as extensions at any card), SSD-001, OC-001 and SD-001 (`openWordList`, `changeLevel`, `resetWordList`, `exit`), DCD-001 (`ProgressRepository.reset`, the menu classes, `Application` commands), DICT-001 and the wireframe (menu bar and dialogs); each changed document gets a Version History row and a review. | No | UC-001, DCD-001 |
 | 2 | Keep the progress of every word list apart | `progress_file_name(list_path)` in one place (`words_to_learn.csv` for `ms-da.csv`, `words_to_learn_<name>.csv` for another list) and `ProgressRepository.reset()` with its CSV adapter (deletes the file, no error when it is absent). | Yes | US-001.09, US-001.11 |
 | 3 | Open another word list | The application loads a CSV chosen in the file dialog (starting in the data folder), validates it before it replaces the list in use, and shows the level choice for it; an invalid file gives a message and no change. | Yes | US-001.09 |
 | 4 | Change level while learning | The application shows the level choice again on the same window and starts the session at the chosen level with the progress kept. | Yes | US-001.10 |
 | 5 | Reset a word list | After a confirmation the application resets the progress of the open list and shows the level choice; the word list file is never changed. | Yes | US-001.11 |
 | 6 | Add the menu bar and the About menu | `MenuViewModel` (entries, labels, order, no Tkinter) and `MenuView` (the Tk menu bar on the window, mnemonics, Exit that cancels the timer, About, Contact entry that opens the LinkedIn page); the contact data and labels are constants. | Yes | US-001.12 |

 ---
 ## Purpose
 Decide whether the project can be handed out as version 0.2.0: the version is raised, the tag `v0.2.0` is made on the commit that is built, and the release page has notes and, when the git host accepts the upload, the executable with its checksum. Version 0.2.0 is the minor release that adds the menu bar and the progress per word list to 0.1.0.
 ## Deliverable
 `pyproject.toml`, `flash_card.__version__` and the `Doxyfile` say `0.2.0`; `CHANGELOG.md` has the entry for 0.2.0; the annotated tag `v0.2.0` is on the head of `main`; the release `v0.2.0` exists with notes; `flash-card.exe` and `flash-card.exe.sha256` are attached if the upload limit of the git host allows it, otherwise the notes say how to build the executable and the open issue stays open.
 ## Go / No-Go Criteria
 | # | Criterion (objectively checkable) | Go | No-Go |
 | --- | --- | --- | --- |
 | 1 | The three version places say `0.2.0` and a test fails when `flash_card.__version__` and `pyproject.toml` differ | Test passes; grep shows the same version | A different version |
 | 2 | `CHANGELOG.md` has a `[0.2.0]` entry listing the menu bar, the progress per word list and the message for a file that is not UTF-8, and `[0.1.0]` is unchanged | File read in the review record | A missing or changed entry |
 | 3 | The upload limit of the git host is probed before the build with a draft release that is deleted afterwards, and the result is recorded | Result in the review record | No probe |
 | 4 | The executable is built with `--clean` from the commit to be tagged and passes the smoke test of MIL-009 (window, embedded list, progress beside it, list override) | Smoke test output in the review record | A failing case |

 ## Tasks
 | # | Task | Summary | Needs its own Use Case/User Story? | Reference |
 | --- | --- | --- | --- | --- |
 | 1 | Update the documents for the release | BC-001 (releases in plural), US-001.08 (the latest release instead of v0.1.0) and PP-001; each changed document gets a Version History row and a review. | No | BC-001, US-001 |
 | 2 | Raise the version to 0.2.0 | `pyproject.toml`, `flash_card.__version__` in `src/flash_card/__init__.py` and `PROJECT_NUMBER` of the `Doxyfile`; one unit test compares the version of the package with `pyproject.toml`, so the places cannot drift. | No | |
 | 3 | Write the CHANGELOG entry and the release notes | `[0.2.0]` with Added (menu bar: open another word list, change level, reset word list, exit, contact; progress kept apart for each word list), Fixed (a file that is not UTF-8 gives a message) and the known limits; the same text is the release body. | No | |
 | 4 | Probe the upload limit of the git host | Create a draft release, try uploads of 1, 5, 10 and 30 MB random files one after another and stop at the first refusal, delete the draft and its tag; record the largest accepted size. The token is read inside the script. | No | |
 | 5 | Build and smoke-test the executable from the tagged commit | `python tools/build_executable.py --clean` from a clean tree of the head of `main` after the version change, the smoke test, and the SHA-256. | Yes | US-001.08 |
 | 6 | Tag v0.2.0 | Annotated tag `v0.2.0` on the head of `main` and push it; `v0.1.0` stays where it is. | No | |
 | 7 | Create the release and attach the files | Create the release `v0.2.0` with the notes through the API; attach `flash-card.exe` and `flash-card.exe.sha256` when the probe allows it and compare the hash after a download; otherwise say so in the notes and leave the issue open. | Yes | US-001.08 |
 | 8 | Link the release | README, CHANGELOG and the Install page of the wiki in English, Danish and Bahasa Malaysia link `v0.2.0`; the wiki is republished. | No | |

 ## Purpose
 Decide whether the program can be built, tested and run without touching the Product Owner's own desktop: a Docker container gives a Debian desktop (GNOME) on a virtual screen, and Windows Sandbox (a disposable Windows virtual machine of Windows 11 Pro) runs the Windows executable on a desktop of its own. The checks that earlier took over the Windows desktop (mouse clicks, windows opening) move into the containers.
 ## Deliverable
 - A Debian image (`python:3.13-slim-bookworm`) with GNOME's window manager and session, a virtual X screen, Tk and fonts, that runs the linters and the whole test suite (including the e2e tests of the real window), the headless run with screenshots, and a PyInstaller build of a Linux binary with its smoke test.
 - A Windows Sandbox check of the Windows executable: a `.wsb` configuration and a PowerShell script (`tools/sandbox/`) that start a disposable Windows 11 virtual machine with the built `dist/` mapped read-only and an output folder mapped read-write, start the executable on the sandbox's own desktop, press the known button inside the sandbox, check the progress file, take screenshots, write the results to the output folder and shut the sandbox down. The mouse and the keyboard used are those of the sandbox, not of the host.
 - macOS is not covered, and the documents say why (see ADR-0005).
 ## Go / No-Go Criteria
 | # | Criterion (objectively checkable) | Go | No-Go |
 | --- | --- | --- | --- |
 | 1 | `docker build` of the Debian image succeeds on the Product Owner's Docker Desktop (Linux containers) | Exit code 0 | A build error |
 | 2 | In the Debian image the linters and the whole test suite run on the virtual screen with the GNOME window manager and end with exit code 0, with the e2e tests counted as passed (not skipped) | Output and exit code | A skipped or failing test |
 | 3 | The full GNOME session (`gnome-session` with its shell) is tried in the container; the result is recorded; when it cannot run in a container the checks use GNOME's window manager (mutter) and the record says so | Result in the review record | An unstated fallback |
 | 4 | During the container runs nothing opens or moves on the host desktop; during a sandbox run the only host effect is the sandbox's own window, and the sandbox is closed by its script | Nothing else seen on the host | A host window other than the sandbox or any host click |
 | 5 | The screenshot script writes the level screen, the card front, the card back and the window with the menu bar as PNG files to a mounted folder, from the Debian image | Four readable PNG files | A missing or blank file |
 | 6 | A Linux binary is built in the container and its smoke test passes: the window appears, the level screen is shown, a known word is pressed through the virtual input of the screen and the progress file has one card less, the list override is used | Script output and exit code 0 for 5 consecutive runs | A failing run |
 | 7 | The Windows executable passes the same smoke test inside Windows Sandbox (window titled Flashy, embedded list, list override, known button writes the progress file), 5 consecutive sandbox runs, with the results read from the mapped output folder | Result files of 5 runs | A failing run, or a run that needs the host mouse |
 | 8 | The lost-click symptom of RC-072 is investigated with the container test (a repeated press of the known button on the same executable) and the finding is recorded: program defect or test harness | Finding in the review record | No finding |
 | 9 | README and the wiki Install page in three languages describe the commands and state that macOS is not covered, that the sandbox needs Windows 11 Pro with Windows Sandbox enabled, and that the Debian check is not a Windows check; `check-readme.sh` exit 0 | Exit code 0 | A missing statement |
 | 10 | BC-001 and PP-001 are updated and ADR-0005 records the decision and its limits (including why macOS is not run in Docker); each reviewed `Go`; code review against QC-PY-001 has no failed Mandatory criterion; the linters are clean | `RC-*` verdict Go | Otherwise |
 ## ## Dependencies
 | Depends on | Reason |
 | --- | --- |
 | MIL-012 | The version 0.2.0 of the program, the built executable and the open condition (RC-072) about its smoke test |
 ## Traceability
 | Business Case objective / KPI / user story | Reference |
 | --- | --- |
 | Objective 4 (a repository others can use) and success criterion 2 (tests run on a clean environment) | [BC-001] |
 | The condition of RC-072 on the executable smoke test (Linux part) | [MIL-012] |
 ## Ownership
 | Role | Stakeholder ID (SA) |
 | --- | --- |
 | Owner | S01 |
 | Approving reviewer | S01 (AI as stand-in in autonomous mode) |
 ## Target Date
 2026-10-19 — within the delivery window that ends 2026-10-21 ([BC-001] constraint).
 ## Tasks
 | # | Task | Summary | Needs its own Use Case/User Story? | Reference |
 | --- | --- | --- | --- | --- |
 | 1 | Update the documents for the container checks | BC-001 (In Scope: Docker images for tests and headless runs; Out of Scope: macOS, a signed or installed Windows setup), PP-001 and a new ADR-0005 (the Debian image with GNOME, Windows Sandbox for the Windows executable, what is covered and why macOS is not run in Docker: Apple's licence allows macOS only on Apple hardware); each changed document gets a Version History row and a review. | No | BC-001, ADR-0004 |
 | 2 | Add the Debian image with GNOME | `docker/debian.Dockerfile` and `.dockerignore`: `python:3.13-slim-bookworm`, `xvfb`, `xauth`, `dbus-x11`, `mutter`, `gnome-session` and `gnome-shell`, `tk`, `fonts-liberation`, `x11-utils`, `xdotool`, a non-root user; the project installed with `[dev,speech,tools,build]`. | No | ADR-0005 |
 | 3 | Start a GNOME session on the virtual screen | `tools/docker/start-desktop.sh` starts `dbus`, Xvfb and `gnome-session` (or, if the session cannot run in a container, mutter alone) and waits until the desktop is up; the choice is printed and recorded. | No | |
 | 4 | Add the check scripts | `tools/docker/run-checks.sh`, `screenshots.sh` and `smoke-binary.sh`; each one purpose, `set -euo pipefail`, shellcheck clean, all run under the desktop of task 3. | No | |
 | 5 | Make the screenshot tool work on Linux | `tools/capture_screenshots.py` chooses the platform: Windows as now, Linux grabs the X screen with Pillow and crops to the window; the pure parts are unit tested. | No | |
 | 6 | Add the headless smoke driver | A script that starts the program or the binary, finds the window with `xdotool`, presses the known button with the virtual input of the screen, and checks the progress file, with a repeat count so the lost-click symptom of RC-072 can be measured; the sandbox script does the same with the sandbox's input. | No | |
 | 7 | Add the Windows Sandbox check | `tools/sandbox/flash-card.wsb` (mapped folders: `dist` read-only, `out` read-write; logon command), `tools/sandbox/smoke.ps1` (runs inside the sandbox: copy the executable, start it, wait for the window, press the known button with the sandbox's own input, read the progress file, take screenshots, write a result file and shut the sandbox down) and `tools/sandbox/run.ps1` on the host (starts the sandbox with the generated configuration and waits for the result file). | No | ADR-0005 |
 | 8 | Run and record the checks | Build the image, run the scripts and the smoke tests 5 times each in the container and 5 times in the sandbox, record counts, sizes, durations and the GNOME session result; record the finding on the lost click. | No | |
 | 9 | Test the pure parts | Unit tests for the platform choice and the box calculation of the capture tool and for the argument handling of the smoke driver. | No | |
 | 10 | Update README and wiki | README and the Install page of the wiki in English, Danish and Bahasa Malaysia: the commands, the output folders, the limits (the Debian check is not a Windows check, the sandbox needs Windows 11 Pro, macOS is not covered); the wiki is republished after the merge. | No | |

 ## Artifact Under Review
 - Instance reviewed: [PY-MIL-007]
 - Checklist used: [QC-PY-001]
 - Scope: full review
 - Language and domain: n/a (technical type)
 - Language reviewer: none
 - Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) | Pass | PEP 8 casing holds in `tools/capture_screenshots.py` and the changed view; ruff rule set N passes. |
 | 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes | Pass | Names state purpose (`capture`, `_make_dpi_aware`, `SCREENSHOT_SEED`). |
 | 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions | Pass | `ruff check` and `ruff format --check` pass on 56 files; the one `type: ignore` is for a Windows-only attribute and says which error it silences. |
 | 4 | Every function and method signature is type-annotated, including `-> None` | Pass | Every signature is annotated; `mypy --strict` passes on `src` (38 files) and on both tool scripts. |
 | 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) | Pass | No exception handling was added. |
 | 6 | No mutable default arguments and no shadowed builtins | Pass | No mutable defaults, no builtin shadowed. |
 | 7 | Files, locks and connections are managed with context managers | Pass | The data copy uses `tempfile.TemporaryDirectory` as a context manager; the Tk root is destroyed. |
 | 8 | Public modules, classes and functions have docstrings that say what, not how | Pass | Module, functions and constants have Doxygen comments; `doxygen Doxyfile` ends with 0 warnings. |
 | 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output | Pass | The tool writes the two output paths with `sys.stdout.write`; no `print`, no secret. |
 | 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded | Pass | The only source change is the button background in `FlashCardView`, which follows `wireframe.md`; the tool is outside the design classes and is not part of the program. |
 | 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network | Pass | 125 tests, 2 consecutive full runs green; one e2e assertion was added for the button background; the tool is checked by running it and reading both images. |
 | 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment | Pass | `mypy --strict` reports no issue on the touched files; no `Any`. |
 | 13 | Dependencies are declared and pinned in the project's dependency file, none unused | Pass | `dependencies` stays empty; Pillow is the optional extra `tools` and is imported only by the tool. |
 | 14 | Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike | Pass | The seed, output folder and delay come from one definition each; the delay is `FLIP_DELAY_MS`. |
 | 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles | Pass | `lint-imports` reports `Layers point inward` kept; the tool imports the composition root only. |
 | 16 | SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations | Pass | The tool has one purpose (capture); the view change adds no rule. |
 | 17 | Source is laid out in the layers and folders of the clean architecture folder structure (`domain`, `application`, `infrastructure`, `presentation` packages under `src/`, and `unit`, `integration` and `e2e` under `tests/`), in `snake_case`, and imports between the layers point inward | Pass | `tools/` holds helper scripts outside `src/`; the layers are unchanged. |
 | 18 | File and folder names are English, contain no space and no character outside letters, digits, `-`, `_` and `.`, and follow the casing of the language for files | Pass | File and folder names follow the rule (`docs/images`, `docs/wiki` pages are exceptions for wiki names). |
 ## Overall Verdict
 Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
 Milestone MIL-007 Go criteria: 1 `check-readme.sh` exit 0 and both screenshots linked from the README; 2 `docs/wiki/` holds Home, Install, Usage and Architecture as `<Page>.md`, `<Page>-da.md`, `<Page>-ms.md` (12 pages) and `_Sidebar.md` listing the three languages; 3 the screenshots are captured from the running program by `tools/capture_screenshots.py` and were inspected; 4 the README Setup and Run need 5 commands (create `.venv`, activate, upgrade pip, install, run); 5 the repository has a description and 10 topics (read back from the API); 6 `doxygen Doxyfile` 0 warnings; 7 `docs/sqa/traceability-matrix.md` has a row for every created artifact with its latest `RC-*`, and the plan links each milestone; 8 `check-languages.sh` exit 0 (`check-plan.sh` is a commit-message hook and was not run). The wiki is pushed to the host's wiki after this merge. The Danish and Malay wiki pages were written by the AI and have not been read by a native speaker; this is stated in the end-of-run summary. All Go.

 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | ROI/Cost-Benefit analysis is quantitative, or where qualitative, is explicitly justified | Pass | The Cost-Benefit table is qualitative and says why: no revenue is expected, so a quantitative return does not apply. |
 | 2 | Risks are identified with documented impact and mitigation | Pass | The Risks table has 5 risks, each with an impact and a mitigation. |
 | 3 | Success criteria are measurable, stating explicit targets rather than vague aspirations | Pass | The Success Criteria table has 8 rows with numeric targets and a measure each (for example 0 third-party packages; 5 commands or fewer). |
 | 4 | Scope explicitly separates In Scope vs Out of Scope | Pass | Scope has `### In Scope` and `### Out of Scope` subsections. |
 | 5 | Stakeholders are cross-referenced to Stakeholder Analysis IDs rather than re-described inline | Pass | The Stakeholders table cites S01, S02 and S03 and does not re-describe their roles. |
 | 6 | Methodology and quality-standard foundation are stated explicitly (e.g. ISO/IEC 25010, Larman) | Pass | Methodological and Standards Foundation names the framework, Larman, ISO/IEC 25010:2023 and PEP 8. |
 | 7 | Assumptions and constraints are explicit and clearly distinguished from one another | Pass | Assumptions and Constraints are separate sections. |
 | 8 | Document supports executive decision-making with a clear, unambiguous recommendation | Pass | Recommendation reads `Proceed` with a one-sentence rationale. |

 ## Artifact Under Review
 - Instance reviewed: [UC-001]
 - Checklist used: [QC-UC-001], and [QC-LANG-001] (language and domain)
 - Scope: full review
 - Language and domain: en / it
 - Language reviewer: none (the stand-in for S01 reads the language and knows the domain)
 - Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | Consists of a single, concise paragraph summarizing only the primary success scenario | N-A | The format is Fully Dressed; the Brief format criterion does not apply. |
 | 2 | Written as an informal multi-paragraph narrative; may mention some alternate flows without formal structure | N-A | The format is Fully Dressed; the Casual format criterion does not apply. |
 | 3 | All standard sections are present: actors, preconditions, postconditions, main success scenario, alternative/exception flows | Pass | Scope, level, actor, stakeholders, pre- and postconditions, main success scenario and extensions are present. |
 | 4 | Preconditions and postconditions are explicitly defined | Pass | Preconditions and postconditions are listed. |
 | 5 | Primary actor is explicitly stated | Pass | Primary actor is `Learner`. |
 | 6 | Stakeholders and their interests are stated | Pass | Stakeholders S01 and S02 and their interests are stated. |
 | 7 | Main success scenario is written as clear, numbered steps | Pass | Main success scenario has 9 numbered steps, including the level choice (steps 2 and 3). |
 | 8 | Alternative/exception flows correctly reference `<<include>>`/`<<extend>>` use cases where relevant, per UML 2.5.1 | Pass | UCD-001 has no include or extend relationship, so no extension needs to reference one; the extensions (3a, 4a, 5a, 7a, 7b, 9a) are plain alternative flows. |
 | 9 | Explicit business rules are captured per step where applicable, rather than embedded loosely in narrative text | Pass | The Business Rules table gives a rule per step. |
 | 10 | Naming of actors and use case title is consistent with the corresponding Use Case Diagram and User Stories | Pass | Title and actor match UCD-001 and US-001; the level step matches US-001.06. |
 | 11 | Scope/level (e.g. summary, user-goal, subfunction) is explicitly stated | Pass | `Level: user-goal` and `Scope: Flash Card program`. |
 | 12 | Use case is written from the actor's goal perspective, free of UI or implementation detail | Pass | Steps are written as goals and answers; buttons, files and milliseconds are in the wireframe and milestones. |
 ## Language and Domain Results

 | --- | --- | --- | --- |
 | 1 | The Metadata table has a `Language` row and a `Domain` row, and neither is a placeholder | Pass | Metadata of UC-001 has `Language | en` and `Domain | it`; neither is a placeholder. |
 | 2 | `Language` is a BCP 47 code and `Domain` is a value from the registry's domain list | Pass | `en` is a BCP 47 code and `it` is a value of the registry's domain list. |
 | 3 | The content (prose and table cells) is written in the stated language | Pass | Prose and table cells are English; Malay and Danish words and file names appear only as quoted data. |
 | 4 | The register matches the one the registry gives for the artifact type | Pass | The registry gives `IT Professional English` for this type; the text is written for that reader. |
 | 5 | Domain terms are the PO terms of the domain's dictionary, with no synonyms | Pass | The PO terms of DICT-001 (flash card, word list, words to learn, study session) are used and no synonym replaces them. |

 | 9 | A reviewer competent in the domain, and in the language, has confirmed that the domain terms are used correctly | Pass | The reviewer is the stand-in for S01, the Product Owner, who reads English and knows the IT domain; no second language reviewer is needed (review-checklist-process step 2). Open to challenge by S01 in the end-of-run summary. |
 | 10 | Abbreviations are spelled out on first use, in the stated language | Fail | CSV, MVVM, UI, PO and similar abbreviations are not all spelled out at first use; Optional, deferred. |
 ## Overall Verdict
 Go — every Mandatory criterion passes; the failed Optional criteria are deferred with an action item. Reviewed by AI as stand-in for S01; not independent of the author.
 Full review (not a delta) after the level choice was added for MIL-008.

 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | SOLID principles applied; no god classes with excessive responsibilities | Pass | Each class has one responsibility (Class Table); view, view model, session, deck and adapters are separate. |
 | 2 | Visibility markers correct and consistent (`+` public, `-` private, `#` protected) | Pass | Visibility markers are on all members. |
 | 3 | Relationships correctly distinguished: Association vs Aggregation vs Composition vs Dependency | Pass | Composition (Vocabulary and Card), aggregation (Deck), composition (LevelViewModel and LevelChoice), association, dependency and realization are distinguished. |
 | 4 | Multiplicities and navigability specified on all associations | Pass | Multiplicities are on the associations; dependencies are directed. |
 | 5 | Applied design patterns are annotated explicitly (e.g. Singleton, Factory, Strategy) | Pass | Pattern Annotations table lists Repository, Ports and adapters, Null Object, MVVM, Composition root. |
 | 6 | Method signatures are traceable to Operation Contracts and/or design Sequence Diagrams | Pass | Method Traceability table maps every operation, including `Level.first`, `Deck.within`, `LevelViewModel.choices` and `LevelView.choose`, to OC-001 and SD-001. |
 | 7 | Class names and structure remain consistent with the Domain Model concepts they refine | Pass | The Class Table has a `Refines` column; `Level` refines the concept Level of DM-001; names match the dictionary's IT terms. |
 | 8 | No circular dependencies between classes/packages unless explicitly justified | Pass | Dependency Check states there are no cycles. |
 | 9 | Dependencies between classes and packages point inward: domain classes do not depend on infrastructure, delivery or framework classes | Pass | Domain imports nothing; infrastructure and presentation point inward (Dependency Check). |
 ## Overall Verdict
 Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
 Full review (not a delta) after the level choice was added for MIL-008.

 - Language reviewer: none
 - Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) | Pass | PEP 8 casing holds in all new modules (`level.py`, `level_view.py`, `window.py`); ruff rule set N passes. |
 | 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes | Pass | Names state purpose and are the dictionary's IT terms (`Level`, `Deck.within`, `LevelViewModel`, `LevelChoice`, `Application.start`). |
 | 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions | Pass | `ruff check` and `ruff format --check` pass on 67 files with no suppressions. |
 | 4 | Every function and method signature is type-annotated, including `-> None` | Pass | Every signature is annotated; `mypy --strict` passes on 44 source files and on `tools/capture_screenshots.py`. |
 | 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) | Pass | `Level` raises `ValueError` for a limit below 1; a failed session start after a click is logged, closes the window with exit code 1 and never swallows silently; no bare `except`. |
 | 6 | No mutable default arguments and no shadowed builtins | Pass | No mutable defaults, no builtin shadowed. |
 | 7 | Files, locks and connections are managed with context managers | Pass | No new file handling beyond the existing context managers. |
 | 8 | Public modules, classes and functions have docstrings that say what, not how | Pass | New and changed members have Doxygen docstrings; `doxygen Doxyfile` ends with 0 warnings. |
 | 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output | Pass | No `print`; failures are logged with `logging`; no personal data is logged. |
 | 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded | Pass | `Level`, `Deck.within`, `Deck.draw(among)`, `StudySession(level_cards)`, `open_study_session(..., level)`, `LevelChoice`, `LevelViewModel`, `LevelView` and `Application` match the revised DCD-001, OC-001 `chooseLevel` and SD-001. Deviations: `Application` (root, repositories, speech) with `start`, `show_level_screen` and `exit_code` is the composition root detail that DCD-001 shows as `app.main`; `StudySession.remaining_in_level` and `LevelView.frame` are additions. |
 | 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network | Pass | 191 tests (3 consecutive full runs green) cover `Level`, `Deck.within`, the level filter, the cross-level progress rules on the real word list, the view model, `--level` and the real level window flow; none uses the network. |
 | 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment | Pass | `mypy --strict` reports no issue; no `Any`. |
 | 13 | Dependencies are declared and pinned in the project's dependency file, none unused | Pass | `dependencies` stays empty; no new package. |
 | 14 | Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike | Pass | The level rule exists only in `Level.first` and `Deck.within`; the choices, labels and sizes exist once in `constants.py`; both views use `configure_window`. |
 | 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles | Pass | `lint-imports` reports `Layers point inward` kept; a grep finds no `tkinter`, `csv` or `random` import in `domain` or `application`; the level view model imports no Tkinter. |
 | 16 | SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations | Pass | The view model owns the choices and the view draws them; the composition root only wires; the session depends on protocols and receives its collaborators. |
 | 17 | Source is laid out in the layers and folders of the clean architecture folder structure (`domain`, `application`, `infrastructure`, `presentation` packages under `src/`, and `unit`, `integration` and `e2e` under `tests/`), in `snake_case`, and imports between the layers point inward | Pass | `presentation/features/level/` and `presentation/shared/` follow the clean-architecture folder structure; tests stay in `unit`, `integration`, `e2e` (with a session-scoped `tk_root` in `tests/e2e/conftest.py`). |
 | 18 | File and folder names are English, contain no space and no character outside letters, digits, `-`, `_` and `.`, and follow the casing of the language for files | Pass | File and folder names follow the rule. |
 ## Overall Verdict
 Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
 Milestone MIL-008 Go criteria: 1 level 100 draws exactly the first 100 rows over a full run of the real list (integration test); 2 levels 1000 and All use all 1000 words, and a shorter list is used whole (unit and integration tests); 3 words known at level 100 stay known at All and the progress file keeps every unknown word, also outside the level (integration test); 4 a level with nothing left gives the finished message and no failure (unit and e2e tests); 5 the level view model has no Tkinter import and its tests pass without a display; 6 `--level 100|1000|all` skips the screen and an unknown value exits with 2 (unit tests); 7 UC-001, DM-001, DICT-001, SSD-001, OC-001, SD-001, DCD-001, BC-001, US-001, PP-001 and MIL-008 were re-reviewed `Go` (RC-030 to RC-040), the wireframe has Screen 1, and the README and the wiki in en, da and ms describe the level; 8 this record, `pytest` 191 passed, ruff, mypy, lint-imports and doxygen clean. A real screenshot of the level screen was captured and inspected after fixing a too-small window. The Danish and Malay wiki additions were written by the AI and are not read by a native speaker. All Go.

 - Scope: full review
 - Language and domain: n/a (technical type)
 - Language reviewer: none
 - Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | SOLID principles applied; no god classes with excessive responsibilities | Pass | Each class has one responsibility (Class Table); view, view model, session, deck and adapters are separate. |
 | 2 | Visibility markers correct and consistent (`+` public, `-` private, `#` protected) | Pass | Visibility markers are on all members. |
 | 3 | Relationships correctly distinguished: Association vs Aggregation vs Composition vs Dependency | Pass | Composition (Vocabulary and Card), aggregation (Deck), association, dependency and realization are distinguished. |
 | 4 | Multiplicities and navigability specified on all associations | Pass | Multiplicities are on the associations; dependencies are directed. |
 | 5 | Applied design patterns are annotated explicitly (e.g. Singleton, Factory, Strategy) | Pass | Pattern Annotations table lists Repository, Ports and adapters, Null Object, MVVM, Composition root. |
 | 6 | Method signatures are traceable to Operation Contracts and/or design Sequence Diagrams | Pass | Method Traceability table is unchanged; the packaging support (`runtime.py`, `tools/`) is stated in Purpose and Scope as having no system operation and not being a design class, so it needs no row. |
 | 7 | Class names and structure remain consistent with the Domain Model concepts they refine | Pass | The Class Table has a `Refines` column; names match the dictionary's IT terms; no class was added. |
 | 8 | No circular dependencies between classes/packages unless explicitly justified | Pass | Dependency Check states there are no cycles. |
 | 9 | Dependencies between classes and packages point inward: domain classes do not depend on infrastructure, delivery or framework classes | Pass | Domain imports nothing; infrastructure and presentation point inward (Dependency Check). |
 ## Overall Verdict
 Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
 Full review (not a delta) after the change for MIL-009 (executable).

 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) | Pass | PEP 8 casing holds in `runtime.py`, `build_executable.py` and the changed modules; ruff rule set N passes. |
 | 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes | Pass | Names state purpose (`resource_root`, `executable_dir`, `build_arguments`, `resolve_data_files`). |
 | 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions | Pass | `ruff check` and `ruff format --check` pass on 71 files with no suppressions. |
 | 4 | Every function and method signature is type-annotated, including `-> None` | Pass | Every signature is annotated; `mypy --strict` passes on 45 source files and on the three tool scripts. |
 | 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) | Pass | `main` of the build tool returns 2 with a message when PyInstaller is not installed; no bare `except`; no swallowed exception. |
 | 6 | No mutable default arguments and no shadowed builtins | Pass | No mutable defaults, no builtin shadowed. |
 | 7 | Files, locks and connections are managed with context managers | Pass | No new file handling beyond the existing context managers; the ICO file is written with `Path.write_bytes`. |
 | 8 | Public modules, classes and functions have docstrings that say what, not how | Pass | New and changed members have Doxygen docstrings; `doxygen Doxyfile` ends with 0 warnings. |
 | 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output | Pass | No `print` in `src`; the tools write results with `sys.stdout.write`; no secret. |
 | 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded | Pass | The program classes are unchanged (DCD-001); `runtime.py` and `tools/` are packaging support outside the design classes, as ADR-0004 and the Scope note of DCD-001 state; `resolve_data_files` is a function of the composition root. |
 | 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network | Pass | 216 tests (3 consecutive runs green): pure runtime helpers for the frozen and source cases, the argument list of the build, the ICO file, the bundled word list fallback, and the level screen window title; none starts PyInstaller or uses the network. The real executable was built and smoke-tested separately (note below). |
 | 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment | Pass | `mypy --strict` reports no issue; `sys._MEIPASS` is read with `getattr` and no `Any` is used. |
 | 13 | Dependencies are declared and pinned in the project's dependency file, none unused | Pass | `dependencies` is still empty; PyInstaller is only in the extra `build` and Pillow only in `tools`. |
 | 14 | Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike | Pass | The frozen rule is one definition (`runtime.py`) used by `constants.py`; file names and sizes stay in `constants.py`. |
 | 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles | Pass | `lint-imports` reports `Layers point inward` kept; `runtime.py` imports only the standard library. |
 | 16 | SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations | Pass | The build tool has one purpose and a pure `build_arguments` that is tested; the composition root chooses the word list file. |
 | 17 | Source is laid out in the layers and folders of the clean architecture folder structure (`domain`, `application`, `infrastructure`, `presentation` packages under `src/`, and `unit`, `integration` and `e2e` under `tests/`), in `snake_case`, and imports between the layers point inward | Pass | `tools/build_executable.py` and `runtime.py` sit outside the four layers as packaging support; layers and test folders are unchanged. |
 | 18 | File and folder names are English, contain no space and no character outside letters, digits, `-`, `_` and `.`, and follow the casing of the language for files | Pass | File and folder names follow the rule. |
 ## Overall Verdict
 Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
 Milestone MIL-009 Go criteria: 1 `python tools/build_executable.py` ended with exit code 0 and wrote `dist/flash-card.exe` (25.8 MB) with PyInstaller 6.22.3 on the Windows Store Python 3.13.14; 2 started from a temporary folder without the virtual environment, the executable showed a window titled `Flashy` after about 2 seconds and has no console (windowed bootloader); 3 with `data/ms-da.csv` beside it (3 words) one tick left 2 cards in the progress file, without it the embedded list was used (1000 words); 4 one tick wrote `data/words_to_learn.csv` next to the executable with 999 cards at level 100; 5 a captured screenshot of the executable shows the card and both button images; 6 unit tests of the frozen rule pass; 7 `dependencies` empty, extra `build`; 8 BC-001, DCD-001, ADR-0004, PP-001, US-001 and MIL-009 were reviewed Go (RC-042 to RC-047), README and the Install page of the wiki in three languages describe the build; 9 this record, `pytest` 216 passed, ruff, mypy, lint-imports and doxygen clean. Defects found by the smoke test and fixed in this milestone: the level screen window had the default title `tk` and no padding because `LevelView` did not call `configure_window`. Notes: the one-file build starts a second process (the bootloader), so a tool that watches a window must not match the first process id; the first start after a build took over 20 seconds on this machine (unpacking and a virus scan) and later starts about 2 seconds; the spoken word was not tested in the executable (the speech packages are collected into it, the network call was not exercised). All Go.

 | 18 | File and folder names are English, contain no space and no character outside letters, digits, `-`, `_` and `.`, and follow the casing of the language for files | Pass | File names unchanged. |
 ## Overall Verdict
 Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
 Defect fixed: an unpatched `app.main` call created a real `tk.Tk()` inside a unit test, which failed in about 1 of 6 full runs (the only Tk process limit and Tcl handle problem seen in MIL-005). Found after the MIL-009 merge, outside any milestone task, so no issue is closed. Go.

 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |

 | 3 | Success criteria are measurable, stating explicit targets rather than vague aspirations | Pass | The Success Criteria table has 8 rows with numeric targets and a measure each (for example 0 third-party packages; 5 commands or fewer). |
 | 4 | Scope explicitly separates In Scope vs Out of Scope | Pass | Scope has `### In Scope` and `### Out of Scope`; the release of the executable is In Scope, an installer and signing stay Out of Scope. |
 | 5 | Stakeholders are cross-referenced to Stakeholder Analysis IDs rather than re-described inline | Pass | The Stakeholders table cites S01, S02 and S03 and does not re-describe their roles. |
 | 6 | Methodology and quality-standard foundation are stated explicitly (e.g. ISO/IEC 25010, Larman) | Pass | Methodological and Standards Foundation names the framework, Larman, ISO/IEC 25010:2023 and PEP 8. |

 # RC-055: Review of the release v0.1.0

 ## Artifact Under Review
 - Instance reviewed: [MIL-010] (the milestone's Go / No-Go criteria, checked against the release v0.1.0)
 - Checklist used: none exists for a release; the seven criteria of MIL-010 are the checklist
 - Scope: full review
 - Language and domain: n/a (record of results)
 - Language reviewer: none
 - Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | The executable is rebuilt from the head of `main` that gets the tag and passes the smoke test | Pass | Built with `--clean` from commit `2c580cc` after removing `build/` and `dist/`; four smoke cases passed (window "Flashy" after about 2 s, embedded list, progress file beside the exe with 999 cards, list override with a 2 word list) |
 | 2 | The tag `v0.1.0` is an annotated tag on that commit and the version files say `0.1.0` | Pass | `git show v0.1.0` shows the annotated tag on `2c580cc`; `pyproject.toml` and `__version__` say `0.1.0` |
 | 3 | The release has the assets `flash-card.exe` and `flash-card.exe.sha256` | Fail | The upload of `flash-card.exe` (25.8 MB) was rejected with `413 Request Entity Too Large` from the server's reverse proxy; a 1 MB test upload was reset as well; only an 82 byte file passed. The checksum asset alone was deleted again, because a checksum without its file is misleading |
 | 4 | The SHA-256 of the file downloaded from the release equals the checksum | Fail | There is no downloadable file; the hash of the local build was `0ac22621ecb8ddad53c5f3d2a35278bebd34cefe458510971106ec52d5bdb47d`, which cannot be verified by others because PyInstaller builds are not bit-for-bit reproducible |
 | 5 | The release notes say unsigned Windows build, the `data` folder and how to build, and give the SHA-256 | Fail | The notes say unsigned, the `data` folder and how to build, and state that the file is not attached; they give no SHA-256 because there is no file |
 | 6 | CHANGELOG, README and the Install page of the wiki link the release; `check-readme.sh` exit 0 | Pass | Links present in all five files and corrected to say the file is not attached; `check-readme.sh` exit 0 |
 | 7 | BC-001, US-001 and PP-001 are updated and reviewed `Go` | Pass | RC-051 to RC-053 |
 ## Overall Verdict
 Go-with-conditions — the tag and the release page exist and the build was verified, but criteria 3, 4 and 5 fail because the server refuses the upload of the executable. The milestone MIL-010 stays open and issue "Create the release and attach the files" stays open until the executable is attached. Reviewed by AI as stand-in for S01; not independent of the author.
 ## Action Items
 | Action | Owner | Due |
 | --- | --- | --- |
 | Raise the upload limit of the git host's reverse proxy (nginx `client_max_body_size`, and Gitea's attachment limit if set) to at least 50 MB, then ask for the attachment of `flash-card.exe` and its SHA-256 to v0.1.0 (or confirm another place to host the file) | S01 | 2026-10-21 |

 - Scope: full review
 - Language and domain: n/a (technical type)
 - Language reviewer: none
 - Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) | Pass | PEP 8 casing holds in the new modules (`menu_view.py`, `menu_view_model.py`, `progress_file_name.py`); ruff rule set N passes. |
 | 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes | Pass | Names state purpose and are the DCD-001 IT terms (`MenuView`, `MenuViewModel`, `Application.open_word_list`, `reset`). |
 | 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions | Pass | `ruff check` and `ruff format --check` pass on 79 files with no suppressions. |
 | 4 | Every function and method signature is type-annotated, including `-> None` | Pass | Every signature is annotated; `mypy --strict` passes on 49 source files and on the three tool scripts. |
 | 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) | Pass | Refused files raise `VocabularyFormatError` with `from` (also for bytes that are not UTF-8), a failed reset is logged and shown, a failed browser start is logged; no bare `except`, nothing swallowed silently. |
 | 6 | No mutable default arguments and no shadowed builtins | Pass | No mutable defaults, no builtin shadowed. |
 | 7 | Files, locks and connections are managed with context managers | Pass | Reading uses `with`; the delete uses `unlink(missing_ok=True)`; the Tk root is destroyed through `exit_application`. |
 | 8 | Public modules, classes and functions have docstrings that say what, not how | Pass | New and changed members have Doxygen docstrings; `doxygen Doxyfile` ends with 0 warnings. |
 | 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output | Pass | No `print`; failures use `logging`; the contact data is public author information given by S01. |
 | 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded | Pass | The new classes match the revised DCD-001 and OC-001/SD-001. Deviations: `MenuEntry` has a third field `underline`; `MenuViewModel` has `file_label` and `contact_menu_label`; `Application` has `word_list_folder` and takes a repository factory; `MenuView` depends on a small `MenuApplication` Protocol to avoid an import cycle. |
 | 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network | Pass | 258 tests (5 consecutive full runs green): unit with fakes only, integration with two word lists, and e2e on the real menu bar with injected dialogs; none uses the network or a real browser. |
 | 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment | Pass | `mypy --strict` reports no issue; no `Any`. |
 | 13 | Dependencies are declared and pinned in the project's dependency file, none unused | Pass | `dependencies` stays empty; `webbrowser`, `tkinter.filedialog` and `tkinter.messagebox` are standard library. |
 | 14 | Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike | Pass | The progress file rule is one function (`progress_file_name`); labels, contact data and dialog texts are constants once. |
 | 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles | Pass | `lint-imports` reports `Layers point inward` kept; a grep finds no `tkinter`, `csv`, `random` or `webbrowser` import in `domain` or `application`; the menu view model imports no Tkinter. |
 | 16 | SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations | Pass | The view model owns the entries and the view draws and asks dialogs; `Application` coordinates; the repositories own their files; dialogs and the browser are injected. |
 | 17 | Source is laid out in the layers and folders of the clean architecture folder structure (`domain`, `application`, `infrastructure`, `presentation` packages under `src/`, and `unit`, `integration` and `e2e` under `tests/`), in `snake_case`, and imports between the layers point inward | Pass | `presentation/features/menu/` and `infrastructure/persistence/` follow the folder structure; tests stay in `unit`, `integration`, `e2e`. |
 | 18 | File and folder names are English, contain no space and no character outside letters, digits, `-`, `_` and `.`, and follow the casing of the language for files | Pass | File and folder names follow the rule. |
 ## Overall Verdict
 Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
 Milestone MIL-011 Go criteria: 1 the menu bar structure and order are read from the real `tk.Menu` (e2e); 2 open valid / invalid / cancelled covered (unit and e2e, including a Latin-1 file and invalid UTF-8 bytes); 3 two lists keep separate progress files, `ms-da.csv` keeps `words_to_learn.csv` (integration); 4 change level shows the level screen and keeps the known words (unit and e2e); 5 reset asks, deletes only the progress file of the open list, never the list file (unit, integration, e2e); 6 About, Contact opens `https://www.linkedin.com/in/tirsvad74` through an injected `webbrowser.open` (unit and e2e); 7 exit cancels the timer and destroys the window (e2e); 8 view model tested without Tkinter; 9 RC-056 to RC-065 `Go`, README and the Usage page of the wiki in three languages describe the menu; 10 this record, `pytest` 258 passed and linters clean. The executable was rebuilt with the menu and passes the smoke test (window, embedded list, list override, progress file). A real browser launch and the native file dialog were not exercised on this machine. Defect found by the reviewer and fixed in this milestone: a file that is not UTF-8 raised `UnicodeDecodeError` instead of a message. All Go.

 | 2 | `Language` is a BCP 47 code and `Domain` is a value from the registry's domain list | Pass | `en` is a BCP 47 code and `it` is a value of the registry's domain list. |
 | 3 | The content (prose and table cells) is written in the stated language | Pass | Prose and table cells are English; Malay and Danish words and file names appear only as quoted data. |
 | 4 | The register matches the one the registry gives for the artifact type | Pass | The registry gives `IT Executive English` for this type; the text is written for that reader. |
 | 5 | Domain terms are the PO terms of the domain's dictionary, with no synonyms | Pass | The PO terms of DICT-001 (flash card, word list, words to learn, study session) are used and no synonym replaces them. |

 | 10 | Abbreviations are spelled out on first use, in the stated language | Fail | CSV, MVVM, UI, PO and similar abbreviations are not all spelled out at first use; Optional, deferred. |
 ## Overall Verdict
 Go — no checklist exists for the Project Plan type; the plan now schedules MIL-012 on 2026-10-18 inside the Business Case constraint (delivery by 2026-10-21) and the language checklist passes. Accepted as the Product Owner's stand-in, after the Product Owner accepted the MIL-012 plan in chat. Reviewed by AI as stand-in for S01; not independent of the author.

 - Language reviewer: none
 - Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | Packages, modules, functions, variables, classes and constants follow PEP 8 casing (`snake_case`, `PascalCase`, `UPPER_SNAKE`) | Pass | The change is one assignment and a test module; names follow PEP 8. |
 | 2 | Names state purpose in the domain's language; no unexplained abbreviations, no single-letter names outside tiny scopes | Pass | `test_version_of_the_package_equals_pyproject_version` and similar names state the behaviour. |
 | 3 | Code is produced by the project's formatter and passes its linter with no unexplained suppressions | Pass | `ruff check` and `ruff format --check` pass with no suppressions. |
 | 4 | Every function and method signature is type-annotated, including `-> None` | Pass | Test functions are annotated `-> None`; `mypy --strict` passes on 49 source files. |
 | 5 | No bare `except:`, no swallowed exceptions; specific exceptions are raised and the cause is kept (`raise ... from`) | Pass | No exception handling in the change. |
 | 6 | No mutable default arguments and no shadowed builtins | Pass | No mutable defaults. |
 | 7 | Files, locks and connections are managed with context managers | Pass | `pyproject.toml` is read with `tomllib` through a `with open` context. |
 | 8 | Public modules, classes and functions have docstrings that say what, not how | Pass | The module docstring keeps `@file` and `@brief`; `doxygen Doxyfile` ends with 0 warnings. |
 | 9 | Logging uses `logging`, not `print`; no secrets or personal data in log output | Pass | No `print`, no logging in the change. |
 | 10 | Classes and operations trace to the Design Class Diagram they implement; deviations are recorded | Pass | No class or operation changed; the version string is not part of the design. |
 | 11 | Tests exist for new behaviour, are named for the behaviour, and do not depend on order or the network | Pass | 3 tests compare `__version__`, `pyproject.toml` and the `Doxyfile` `PROJECT_NUMBER` and the `MAJOR.MINOR.PATCH` form; 3 consecutive full runs (261 tests) green. |
 | 12 | Type checker runs in strict mode without errors; `Any` is justified in a comment | Pass | `mypy --strict` reports no issue. |
 | 13 | Dependencies are declared and pinned in the project's dependency file, none unused | Pass | `dependencies` stays empty; `tomllib` is standard library. |
 | 14 | Each piece of knowledge (a business rule, constant, format, validation or query) is defined in one place; code is merged only where it expresses the same knowledge, not where it merely looks alike | Pass | The version is stated once per file type; the test makes the three places agree. |
 | 15 | Imports point inward: business-rule modules import no framework, database, UI or delivery-mechanism code, and there are no import cycles | Pass | `lint-imports` reports `Layers point inward` kept. |
 | 16 | SOLID holds: a class or module has one reason to change; new behaviour is added by extension, not by editing a type test in several places; subclasses honour the contract of their base; protocols are narrow; high-level code depends on protocols or abstract types and receives its implementations | Pass | One test module with one reason to change. |
 | 17 | Source is laid out in the layers and folders of the clean architecture folder structure (`domain`, `application`, `infrastructure`, `presentation` packages under `src/`, and `unit`, `integration` and `e2e` under `tests/`), in `snake_case`, and imports between the layers point inward | Pass | The test sits in `tests/unit`. |
 | 18 | File and folder names are English, contain no space and no character outside letters, digits, `-`, `_` and `.`, and follow the casing of the language for files | Pass | File names follow the rule. |
 ## Overall Verdict
 Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
 Milestone MIL-012 tasks 2, 3, 4 and 8 (this change set): 1 the three version places say 0.2.0 and a test fails if they differ; 2 CHANGELOG has `[0.2.0]` and `[0.1.0]` is unchanged; 3 the upload limit probe ran before the build: a draft release with a 1 MB random file was refused with `413 Request Entity Too Large`, so the largest accepted size is below 1 MB; the draft release and its tag were deleted afterwards (the tag list and the release list were checked); 8 README, CHANGELOG and the Install page of the wiki in three languages link v0.2.0 and say that the executable is not attached; `check-readme.sh` exit 0. The tag, the build and the release are criteria 4 to 7 and are recorded in a separate review record. Go.

 # RC-072: Review of the release v0.2.0

 ## Artifact Under Review
 - Instance reviewed: [MIL-012] (the milestone's Go / No-Go criteria, checked against the release v0.2.0)
 - Checklist used: none exists for a release; the nine criteria of MIL-012 are the checklist
 - Scope: full review
 - Language and domain: n/a (record of results)
 - Language reviewer: none
 - Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)
 ## Checklist Results
 | # | Criterion | Status | Evidence/Notes |
 | --- | --- | --- | --- |
 | 1 | The three version places say `0.2.0` and a test fails when they differ | Pass | `pyproject.toml`, `flash_card.__version__` and `Doxyfile` say 0.2.0; `tests/unit/test_version.py` (3 tests) |
 | 2 | `CHANGELOG.md` has a `[0.2.0]` entry (menu bar, progress per word list, UTF-8 message) and `[0.1.0]` is unchanged | Pass | Read in the pull request #94 |
 | 3 | The upload limit of the git host is probed before the build with a draft release that is deleted afterwards, and the result is recorded | Pass | A draft release with a 1 MB random file was refused with `413 Request Entity Too Large`; the draft and its tag were deleted (release and tag lists checked) |
 | 4 | The executable is built with `--clean` from the commit to be tagged and passes the smoke test of MIL-009 | Fail | Built with `--clean` from `d7ca24d` (25.8 MB). The first smoke run passed three cases (level screen window, embedded list, progress file with 999 cards at level 100); the list override case failed once because the simulated mouse click did not register, and in 3 of 8 reruns the same click was lost. The cause was not found: it may be the click automation (timing of the pointer and the focus) or a defect of the program. The checks were stopped at the Product Owner's request because they take over the desktop, and are to be repeated in a container or on an isolated desktop (MIL-013) |
 | 5 | The tag `v0.2.0` is an annotated tag on that commit; `v0.1.0` is not moved | Fail | The tag points to `d7ca24d` and `v0.1.0` is unchanged (`2c580cc`), but the tag is lightweight: the push of my annotated tag failed on a connection error, and the release creation through the API then created a lightweight tag. Replacing it needs a force update of a tag, which is outside what an autonomous run may do without the Product Owner |
 | 6 | The release `v0.2.0` is published with notes (new, unsigned, `data` folder rule, how to build) | Pass | Release page returns HTTP 200; notes say what is new, that the file is unsigned, the `data` folder and how to build |
 | 7 | When the probe did not allow it: the notes say so and the issue "attach the files" stays open | Pass | The notes state that the executable is not attached and why; issue "Create the release and attach the files" stays open |
 | 8 | README, CHANGELOG and the Install page of the wiki in three languages link `v0.2.0`; `check-readme.sh` exit 0 | Pass | Merged in #94; wiki republished |
 | 9 | `pytest`, `ruff`, `mypy --strict`, `lint-imports` and `doxygen` are clean; BC-001, US-001 and PP-001 reviewed `Go` | Pass | 261 passed; RC-067 to RC-069 |
 ## Overall Verdict
 Go-with-conditions — the version, the CHANGELOG, the tag (lightweight) and the release page are in place, and the executable is correctly stated as not attached. Criteria 4 and 5 fail or are incomplete: the smoke test of the executable is not complete, and the tag is not annotated. Reviewed by AI as stand-in for S01; not independent of the author.
 ## Action Items
 | Action | Owner | Due |
 | --- | --- | --- |
 | Decide whether the lightweight tag `v0.2.0` may be replaced by an annotated tag on the same commit (a force update of the tag on the host); `v0.1.0` stays | S01 | 2026-10-18 |
 | Repeat the smoke test of the executable on an isolated desktop or in a container and find the cause of the lost click (criterion 4), then close the issue "Build and smoke-test the executable" | S01 | 2026-10-21 |
 | Attach `flash-card.exe` and its checksum when the git host's upload limit is raised (issue "Create the release and attach the files") | S01 | 2026-10-21 |

 | 10 | Abbreviations are spelled out on first use, in the stated language | Fail | CSV, MVVM, UI, PO and similar abbreviations are not all spelled out at first use; Optional, deferred. |
 ## Overall Verdict
 Go — no checklist exists for the Project Plan type; the plan now schedules MIL-013 on 2026-10-19 inside the Business Case constraint (delivery by 2026-10-21) and the language checklist passes. Accepted as the Product Owner's stand-in, after the Product Owner accepted the MIL-013 plan in chat. Reviewed by AI as stand-in for S01; not independent of the author.

 ### Pattern Annotations
 | Pattern (GRASP / GoF) | Applied to | Rationale |
 | --- | --- | --- |
 | Information Expert | `Deck.draw` | The deck knows its cards |
 ### Postcondition Coverage
 | Postcondition (from contract) | Satisfied by message |
 | --- | --- |
 | A different card of the level was chosen when two or more exist | `within(level_cards)`, `draw(choose, exclude=current, among=candidates)` |
 | Deck and file unchanged | no `remove` or `save` message |
 | The Malay word was passed to the `SpeechPort` | `speak(card.front, front_code)` |
 ### Responsibility Check
 Same as `markKnown`; the session is the only object that speaks and draws.

-The extensions 2a, 3a, 5b and 7a of [UC-001] add no system operation of their own (they are errors, speech and timer handling inside the three operations above); their behaviour is in [OC-001] as exceptions.

+| 9 | showContact | none | the author's name and title; the link is opened | *a.4 |
 | 10 | exit | none | none; the program ends | *a.5 |
 The turn-over in step 3 is started by the system's own timer, not by a message from the Learner; it is shown as a return without a call, which is the one deviation from "every return answers a message". When the level is given at start (extension 3a of [UC-001]) the Learner's first message is `chooseLevel` and `startStudySession` is not sent.
 ## Alternate Flows
 The extensions 3a, 4a, 5a, 7b and 9a of [UC-001] add no system operation of their own (they are errors, speech, timer and level handling inside the operations above); their behaviour is in [OC-001] as exceptions. They are out of scope of this diagram, which shows the main success scenario with `markUnknown` as the one alternate answer.
 ## Lifecycle Notes
 The system instance lives for one run of the program. The words to learn are created when the level is chosen and saved after each `markKnown`.

+1. The Learner starts the program.
-3. The system shows a random card with the word in Malay.
+2. The system offers the levels: 100 words, 1000 words and all words.
-4. After three seconds the system turns the card over and shows the translation in Danish.
+3. The Learner chooses a level.
-5. The Learner states that the word is known.
+4. The system loads the words to learn: from the kept progress when it exists, otherwise from the word list.
-6. The system removes the word from the words to learn and keeps the words to learn.
+5. The system shows a random card, with the word in Malay, from the first words of the word list that fit the level and are still to learn.
-7. The system shows a new random card, and the Learner repeats from step 4 until no word is left.
+6. After three seconds the system turns the card over and shows the translation in Danish.
-
+7. The Learner states that the word is known.
-### Extensions (Alternative / Exception Flows)
+8. The system removes the word from the words to learn and keeps the words to learn.
-
+9. The system shows a new random card of the level, and the Learner repeats from step 6 until no word is left at the level.
- 3a. Spoken words are available on the Learner's machine:
+
-  1. The system speaks the Malay word. If speaking fails, the system logs it and goes on.
+### Extensions (Alternative / Exception Flows)
- 5a. The Learner states that the word is not known:
+
-  1. The system keeps the word in the words to learn and shows a new random card; the Learner goes on at step 4.
+- 3a. The Learner has given the level when starting the program:
- 5b. The Learner answers before three seconds have passed:
+  1. The system skips steps 2 and 3 and goes on at step 4.
-  1. The system cancels the turn-over of the card being shown and starts a new one for the next card.
+- 5a. Spoken words are available on the Learner's machine:
- 7a. No word is left:
+  1. The system speaks the Malay word. If speaking fails, the system logs it and goes on.
-  1. The system tells the Learner that there is nothing left to learn, and further answers change nothing.
+- 7a. The Learner states that the word is not known:
- 2a. The kept progress or the word list is unreadable:
+  1. The system keeps the word in the words to learn and shows a new random card of the level; the Learner goes on at step 6.

+- *a. At any time the Learner uses a menu command:
-| 4 | The turn-over comes three seconds after the card appears |
+  1. Open a word list: the system asks for a file and checks it; when it is a word list, the system replaces the word list in use and goes on at step 2; when it is not, the system tells the Learner why and keeps the word list in use. When the Learner cancels nothing changes.
-| 6 | A word is identified by its Malay and Danish text; the first equal word is removed |
+  2. Change level: the system goes on at step 2 with the word list in use; the kept progress stays.
-| 2 | The word list names its two languages and holds one word and one translation per card |
+  3. Reset word list: the system asks the Learner to confirm; on yes it removes the kept progress of the word list in use and goes on at step 2, so all its words are to learn again; on no nothing changes.
-
+  4. Contact: the system shows the author's name and title and opens the author's LinkedIn page in the web browser.
-### Open Issues
+  5. Exit: the system ends the program.
-
+
- Starting again (resetting the kept progress) is not offered in the program; deleting the kept progress does it.

 # Wireframe: Study Flash Cards
 _Revision 2026-10-14: the level screen (screen 1) was added for US-001.06. It was drawn by the AI from the use case because the Product Owner gave no wireframe for it; S01 may change it._
 The Product Owner gave this screen in the first prompt (the course's target screenshot). The presentation layer implements it and does not redesign it. Source use case: [UC-001](./uc.md).

 ### US-001.07 — Start without Python
 **As a** Learner, **I want** to start the program by opening one executable file, **so that** I can learn without installing Python or a virtual environment.
 **Acceptance Criteria**
 - Given the executable was built, when I open it on a Windows computer without Python, then the level screen appears and no console window opens.
 - Given I mark a word as known in the executable, when I open it again, then the known word does not come up (my progress is kept in `data/words_to_learn.csv` next to the executable).
 - Given a `data/ms-da.csv` exists next to the executable, when the program starts, then that word list is used; otherwise the word list inside the executable is used.
 - Given the speech extra was included in the build and a network is available, when a card is shown, then the Malay word is spoken; without a network the program works silently.

 ### US-001.08 — Download the executable
 **As a** Learner, **I want** to download the executable from a release page of the repository, **so that** I can use the program without building it.
 **Acceptance Criteria**
 - Given a release exists (for example `v0.2.0`), when I open the releases page of the repository, then I find release notes and, when the git host accepts the upload, `flash-card.exe` and a checksum file attached to it.
 - Given I downloaded `flash-card.exe`, when I compute its SHA-256 hash, then it equals the value in the checksum file and in the release notes.
 - Given I read the release notes, when I look for what the file is, then they say that it is an unsigned Windows build, what the `data` folder next to it holds, and how to build it myself.

 ### US-001.09 — Open another word list
 **As a** Learner, **I want** to open another word list from a CSV file with the File menu, **so that** I can learn another language pair than the one delivered.
 **Acceptance Criteria**
 - Given the program is running, when I choose File, Open, then a file dialog lets me pick a CSV file that starts in the data folder.
 - Given I picked a valid word list, when the dialog closes, then I choose a level and the cards come from that list, and my progress in it is kept apart from the progress in other lists.
 - Given I picked a file that is not a word list (no header of two language codes, or a row that is not two cells), when the dialog closes, then a message names the problem and the earlier word list stays in use.
 - Given I cancel the dialog, when it closes, then nothing changes.

 **Acceptance Criteria**
 - Given a word list is open, when I choose File, Reset word list, then I am asked to confirm and the message names the word list.
 - Given I confirm, when the reset is done, then the progress of that word list is gone, all its words are to learn again and the level choice is shown; the progress of other word lists and the word list file itself are not changed.

 # Arkitektur
 🌐 [English](Architecture) · **Dansk** · [Bahasa Malaysia](Architecture-ms)
 Programmet er bygget i fire lag under `src/flash_card/`. Importer peger indad; `lint-imports` kontrollerer det.
 | Lag | Indeholder | Må importere |
 | --- | --- | --- |
 | `domain` | `Card`, `LanguagePair`, `Level`, `Vocabulary`, `Deck`, fejlene og repository-grænsefladerne | ingenting |
 | `application` | `StudySession`, `open_study_session`, `CardDto` og `SpeechPort` | `domain` |
 | `infrastructure` | CSV-repositories og tale-adaptere | `application`, `domain` |
 | `presentation` | `FlashCardView`, `FlashCardViewModel` (MVVM) og kompositionsroden `app.py` | alle lag |
 Alle konstanter står i `src/flash_card/constants.py`.
 ## Hvor er hvert opgavetrin?
 | Opgave | Kode |
 | --- | --- |
 | Trin 1: vindue, lærred, billede, tekster, knapper | `FlashCardView.__init__` i `presentation/features/flash_card/flash_card_view.py`; billederne laves af `tools/generate_images.py` |
 | Trin 2: læs CSV, tilfældigt ord ved hvert tryk | `CsvVocabularyRepository` og `read_word_list` (erstatter `pandas`), `Deck.draw`, `StudySession.next_card`, `FlashCardView.next_card` |
 | Trin 3: vend efter 3 sekunder | `FlashCardView.flip_card`, `FlashCardView.flip_timer` (`after`, `after_cancel`), `FlashCardViewModel.flip_card` |
 | Trin 4: kendte ord, `words_to_learn.csv` | `FlashCardView.is_known`, `StudySession.mark_known`, `CsvProgressRepository`, `open_study_session` |
 | Ekstra: niveauvalg | `Level`, `Deck.within`, `StudySession.next_card`, `open_study_session`, `LevelView`, `LevelViewModel`, `Application.start` i `presentation/app.py` |
 | Ekstra: tale | `SpeechPort`, `GttsSpeech`, `NullSpeech`, `build_speech` i `presentation/app.py` |
 ## Hvorfor en lagdelt løsning til en lille opgave?
 Reglerne (hvilket kort der kommer næste gang, hvad et kendt ord gør) testes uden vindue og uden filsystem. Vinduet, CSV-filerne og taletjenesten kan udskiftes uden at røre reglerne. Se ADR-0001 og ADR-0002 i `docs/adr/`.
 ## Test
 | Mappe | Hvad den tester |
 | --- | --- |
 | `tests/unit/` | Hvert lag for sig, med falske objekter til portene |
 | `tests/integration/` | Den rigtige ordliste og fremgangsfilen i en midlertidig mappe |
 | `tests/e2e/` | Det rigtige Tkinter-vindue (springes over uden skærm) |

 # Seni bina

 Program dibina dalam empat lapisan di bawah `src/flash_card/`. Import menuju ke dalam; `lint-imports` memeriksanya.
 | Lapisan | Mengandungi | Boleh mengimport |
 | --- | --- | --- |
 | `domain` | `Card`, `LanguagePair`, `Level`, `Vocabulary`, `Deck`, ralat dan antara muka repositori | tiada |

 | `presentation` | `FlashCardView`, `FlashCardViewModel` (MVVM) dan akar komposisi `app.py` | semua lapisan |
 Semua pemalar terdapat dalam `src/flash_card/constants.py`.
 ## Di manakah setiap langkah tugasan?
 | Tugasan | Kod |
 | --- | --- |
 | Langkah 1: tetingkap, kanvas, imej, teks, butang | `FlashCardView.__init__` dalam `presentation/features/flash_card/flash_card_view.py`; imej dibuat oleh `tools/generate_images.py` |
 | Langkah 2: baca CSV, perkataan rawak setiap tekanan | `CsvVocabularyRepository` dan `read_word_list` (menggantikan `pandas`), `Deck.draw`, `StudySession.next_card`, `FlashCardView.next_card` |
 | Langkah 3: terbalik selepas 3 saat | `FlashCardView.flip_card`, `FlashCardView.flip_timer` (`after`, `after_cancel`), `FlashCardViewModel.flip_card` |
 | Langkah 4: perkataan diketahui, `words_to_learn.csv` | `FlashCardView.is_known`, `StudySession.mark_known`, `CsvProgressRepository`, `open_study_session` |
 | Tambahan: pilihan tahap | `Level`, `Deck.within`, `StudySession.next_card`, `open_study_session`, `LevelView`, `LevelViewModel`, `Application.start` dalam `presentation/app.py` |
 | Tambahan: suara | `SpeechPort`, `GttsSpeech`, `NullSpeech`, `build_speech` dalam `presentation/app.py` |
 ## Mengapa program berlapis untuk tugasan kecil?
 Peraturan (kad mana yang seterusnya, apa yang berlaku apabila perkataan diketahui) diuji tanpa tetingkap atau sistem fail. Tetingkap, fail CSV dan perkhidmatan suara boleh diganti tanpa menyentuh peraturan. Lihat ADR-0001 dan ADR-0002 dalam `docs/adr/`.
 ## Ujian
 | Folder | Apa yang diuji |

 # Architecture
 🌐 **English** · [Dansk](Architecture-da) · [Bahasa Malaysia](Architecture-ms)
 The program is built in four layers under `src/flash_card/`. Imports point inward; `lint-imports` checks this.
 | Layer | Holds | May import |
 | --- | --- | --- |
 | `domain` | `Card`, `LanguagePair`, `Level`, `Vocabulary`, `Deck`, the errors and the repository interfaces | nothing |
 | `application` | `StudySession`, `open_study_session`, `CardDto` and `SpeechPort` | `domain` |
 | `infrastructure` | The CSV repositories and the speech adapters | `application`, `domain` |
 | `presentation` | `FlashCardView`, `FlashCardViewModel` (MVVM) and the composition root `app.py` | all layers |
 All constants are in `src/flash_card/constants.py`.
 ## Where is each assignment step?
 | Assignment | Code |
 | --- | --- |
 | Step 1: window, canvas, image, texts, buttons | `FlashCardView.__init__` in `presentation/features/flash_card/flash_card_view.py`; images made by `tools/generate_images.py` |
 | Step 2: read the CSV, random word on each press | `CsvVocabularyRepository` and `read_word_list` (replace `pandas`), `Deck.draw`, `StudySession.next_card`, `FlashCardView.next_card` |
 | Step 3: flip after 3 seconds | `FlashCardView.flip_card`, `FlashCardView.flip_timer` (`after`, `after_cancel`), `FlashCardViewModel.flip_card` |
 | Step 4: known words, `words_to_learn.csv` | `FlashCardView.is_known`, `StudySession.mark_known`, `CsvProgressRepository`, `open_study_session` |
 | Extra: level choice | `Level`, `Deck.within`, `StudySession.next_card`, `open_study_session`, `LevelView`, `LevelViewModel`, `Application.start` in `presentation/app.py` |
 | Extra: speech | `SpeechPort`, `GttsSpeech`, `NullSpeech`, `build_speech` in `presentation/app.py` |
 ## Why a layered program for a small assignment?
 The rules (which card comes next, what a known word does) are tested without a window or a file system. The window, the CSV files and the speech service can be replaced without touching the rules. See ADR-0001 and ADR-0002 in `docs/adr/`.
 ## Tests
 | Folder | What it tests |
 | --- | --- |
 | `tests/unit/` | Each layer alone, with fakes for the ports |
 | `tests/integration/` | The real word list and the progress file in a temporary folder |
 | `tests/e2e/` | The real Tkinter window (skipped when no display exists) |
 ## Project documents
 The business case, plan, design and review records are in `docs/`. The work was done in seven milestones, one pull request each: see `docs/milestones/`.

 # Flash Card
 🌐 **English** · [Dansk](Home-da) · [Bahasa Malaysia](Home-ms)
 A flash card program for learning the most frequent Malay words with their Danish translations. It is the solution of day 31 of Udemy's *100 Days of Code: The Complete Python Pro Bootcamp*.
 ![The level screen: choose 100 words, 1000 words or all words](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/raw/branch/main/docs/images/screenshot-level.png)

 ## The four assignment steps
 | Step | What the program does | Milestone |
 | --- | --- | --- |
 | 1. User interface | A window with a card and two buttons | MIL-002 |
 | 2. New flash cards | A random word from the word list on every button press | MIL-003 |
 | 3. Flip the cards | After 3 seconds the card shows the Danish translation | MIL-004 |
 | 4. Save your progress | Known words are removed and the rest is saved in `words_to_learn.csv` | MIL-005 |
 | Extra | The Malay word is spoken (optional) | MIL-006 |
 | Extra | You choose a level first: the first 100 words, the first 1000 words or all words | MIL-008 |
 ## For course participants
 The function names of the assignment are kept: `next_card`, `flip_card`, `is_known`, and the attributes `flip_timer` and `current_card`. The data is read with the standard library `csv` module instead of `pandas`, so the core program has no runtime dependency.

 # Installation
 🌐 [English](Install) · **Dansk** · [Bahasa Malaysia](Install-ms)
 ## Krav
 - Python 3.13 eller nyere med Tkinter (på Debian eller Ubuntu: `sudo apt install python3-tk`).
 - `git`.
 - Valgfrit: en internetforbindelse og tilvalget `speech`, hvis du vil høre det malajiske ord.
 ## Hent koden
 ```bash
 git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card.git
 cd 031-flash-card
 ```
 ## Opret og brug et lokalt virtuelt miljø
 Windows (PowerShell):
 ```powershell
 python -m venv .venv
 .\.venv\Scripts\Activate.ps1
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 Linux og macOS:
 ```bash
 python3 -m venv .venv
 source .venv/bin/activate
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 - `.[dev]` tilføjer `pytest`, `ruff`, `mypy` og `import-linter`. Brug `.`, hvis du kun vil køre programmet.
 - Hvis PowerShell nægter at køre `Activate.ps1`, så kør `Set-ExecutionPolicy -Scope CurrentUser RemoteSigned` én gang.
 - Forlad miljøet med `deactivate`; slet mappen `.venv` for at starte forfra.
 ## Udtalt malajisk ord (valgfrit)
 ```bash
 python -m pip install -e ".[speech]"
 ```
 Det installerer `gTTS` og `playsound==1.2.2`. Uden tilvalget virker programmet uden lyd.
 ## Kør og test
 ```bash
 python -m flash_card
 python -m pytest
 ```
 Vinduestesten i `tests/e2e/` springes over, når der ikke er en skærm.
 ## Udgivelse og programfil (Windows)
 Udgivelsessiderne for [v0.2.0](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/releases/tag/v0.2.0) og [v0.1.0](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/releases/tag/v0.1.0) har udgivelsesnoterne. Programfilen er endnu ikke vedhæftet, fordi serverens grænse for upload afviser en fil af denne størrelse (HTTP 413); byg den som beskrevet nedenfor. Filen er ikke signeret, så Windows kan vise en SmartScreen-advarsel.
 ## Byg en programfil (Windows)
 ```powershell
 python -m pip install -e ".[build,speech]"
 python tools/build_executable.py
 ```
 Scriptet bruger PyInstaller og skriver `dist/flash-card.exe`: én fil uden konsolvindue, med billeder, ordliste og udtalen indeni. Dobbeltklik for at starte; Python er ikke nødvendigt for at køre den.
 - Din fremgang gemmes i en `data/`-mappe ved siden af programfilen (`data/words_to_learn.csv`).
 - En `data/ms-da.csv` ved siden af programfilen erstatter ordlisten indeni.
 - `python tools/build_executable.py --no-speech` udelader talepakkerne; `--clean` bygger forfra.
 - Programfilen er ikke i repositoryet. Byg den på det system, hvor den skal køre; Windows kan vise en SmartScreen-advarsel, fordi filen ikke er signeret.

 # Pemasangan
 🌐 [English](Install) · [Dansk](Install-da) · **Bahasa Malaysia**
 ## Keperluan
 - Python 3.13 atau lebih baharu dengan Tkinter (pada Debian atau Ubuntu: `sudo apt install python3-tk`).
 - `git`.
 - Pilihan: sambungan internet dan tambahan `speech` jika anda mahu mendengar perkataan Melayu.
 ## Dapatkan kod
 ```bash
 git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card.git
 cd 031-flash-card
 ```
 ## Cipta dan gunakan persekitaran maya setempat
 Windows (PowerShell):
 ```powershell
 python -m venv .venv
 .\.venv\Scripts\Activate.ps1
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 Linux dan macOS:
 ```bash
 python3 -m venv .venv
 source .venv/bin/activate
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 - `.[dev]` menambah `pytest`, `ruff`, `mypy` dan `import-linter`. Gunakan `.` jika anda hanya mahu menjalankan program.
 - Jika PowerShell enggan menjalankan `Activate.ps1`, jalankan `Set-ExecutionPolicy -Scope CurrentUser RemoteSigned` sekali.
 - Keluar daripada persekitaran dengan `deactivate`; padam folder `.venv` untuk bermula semula.
 ## Perkataan Melayu bersuara (pilihan)
 ```bash
 python -m pip install -e ".[speech]"
 ```
 Ini memasang `gTTS` dan `playsound==1.2.2`. Tanpa tambahan ini program berfungsi tanpa bunyi.
 ## Jalankan dan uji
 ```bash
 python -m flash_card
 python -m pytest

 Ujian tetingkap dalam `tests/e2e/` dilangkau apabila tiada paparan.
 ## Keluaran dan fail boleh laku (Windows)
 Halaman keluaran [v0.2.0](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/releases/tag/v0.2.0) dan [v0.1.0](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/releases/tag/v0.1.0) mempunyai nota keluaran. Fail boleh laku belum dilampirkan di sana kerana had muat naik pelayan menolak fail sebesar ini (HTTP 413); bina seperti yang diterangkan di bawah. Fail tidak ditandatangani, jadi Windows mungkin menunjukkan amaran SmartScreen.
 ## Bina fail boleh laku (Windows)
 ```powershell
 python -m pip install -e ".[build,speech]"
 python tools/build_executable.py
 ```
 Skrip menggunakan PyInstaller dan menulis `dist/flash-card.exe`: satu fail tanpa tetingkap konsol, dengan imej, senarai perkataan dan suara di dalamnya. Klik dua kali untuk memulakan; Python tidak diperlukan untuk menjalankannya.
 - Kemajuan anda disimpan dalam folder `data/` di sebelah fail boleh laku (`data/words_to_learn.csv`).
 - `data/ms-da.csv` di sebelah fail boleh laku menggantikan senarai perkataan di dalamnya.
 - `python tools/build_executable.py --no-speech` meninggalkan pakej suara; `--clean` membina semula dari awal.
 - Fail boleh laku tidak disimpan dalam repositori. Bina di sistem tempat ia akan dijalankan; Windows mungkin menunjukkan amaran SmartScreen kerana fail tidak ditandatangani.

 # Install
 🌐 **English** · [Dansk](Install-da) · [Bahasa Malaysia](Install-ms)
 ## Requirements
 - Python 3.13 or later with Tkinter (on Debian or Ubuntu: `sudo apt install python3-tk`).
 - `git`.
 - Optional: an internet connection and the `speech` extra to hear the Malay word.
 ## Get the code
 ```bash
 git clone https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card.git
 cd 031-flash-card
 ```
 ## Create and use a local virtual environment
 Windows (PowerShell):
 ```powershell
 python -m venv .venv
 .\.venv\Scripts\Activate.ps1
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 Linux and macOS:
 ```bash
 python3 -m venv .venv
 source .venv/bin/activate
 python -m pip install --upgrade pip
 python -m pip install -e ".[dev]"
 ```
 - `.[dev]` adds `pytest`, `ruff`, `mypy` and `import-linter`. Use `.` if you only want to run the program.
 - If PowerShell refuses to run `Activate.ps1`, run `Set-ExecutionPolicy -Scope CurrentUser RemoteSigned` once.
 - Leave the environment with `deactivate`; delete the `.venv` folder to start over.
 ## Spoken Malay word (optional)
 ```bash
 python -m pip install -e ".[speech]"
 ```
 This installs `gTTS` and `playsound==1.2.2`. Without it the program works silently.
 ## Run and test
 ```bash
 python -m flash_card
 python -m pytest
 ```
 The window test in `tests/e2e/` is skipped when no display is available.
 ## Release and executable (Windows)
 The release pages of [v0.2.0](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/releases/tag/v0.2.0) and [v0.1.0](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/releases/tag/v0.1.0) have the release notes. The executable is not attached there yet, because the server's upload limit rejects a file of this size (HTTP 413); build it as described below. The file is not signed, so Windows may show a SmartScreen warning.
 ## Build an executable (Windows)
 ```powershell
 python -m pip install -e ".[build,speech]"
 python tools/build_executable.py
 ```
 The script uses PyInstaller and writes `dist/flash-card.exe`: one file, no console window, with the images, the word list and the spoken word inside. Double-click it to start; Python is not needed to run it.
 - Your progress is kept in a `data/` folder next to the executable (`data/words_to_learn.csv`).
 - A `data/ms-da.csv` next to the executable replaces the word list inside it.
 - `python tools/build_executable.py --no-speech` leaves the speech packages out; `--clean` rebuilds from scratch.
 - The executable is not committed to the repository. Build it on the system you want to run it on; Windows may show a SmartScreen warning because the file is not signed.

 # Brug
 🌐 [English](Usage) · **Dansk** · [Bahasa Malaysia](Usage-ms)
 ## Øv kortene
 1. Start programmet med `python -m flash_card`.
 2. Vælg et niveau: **100 words**, **1000 words** eller **All words**. Ordlisten er sorteret fra det hyppigste til det sjældneste ord, så niveau 100 er de 100 hyppigste ord.
 3. Et kort viser et malajisk ord. Prøv at huske den danske oversættelse.
 4. Efter tre sekunder vender kortet og viser oversættelsen.
 5. Tryk på det grønne flueben, hvis du kendte ordet, eller på det røde kryds, hvis du ikke gjorde.
 6. Et nyt tilfældigt ord fra niveauet vises. Gentag.
 Et ord, du har markeret som kendt, fjernes og kommer ikke igen. Når der ikke er flere ord på niveauet, står der "Nothing left to learn" på kortet; start programmet igen og vælg et højere niveau.
 ## Menulinjen

 Fremgangen for den medfølgende `ms-da.csv` er `data/words_to_learn.csv`; en anden liste får `data/words_to_learn_<navn>.csv`. Den åbnede liste huskes ikke efter en genstart.
 ## Din fremgang
 - Første gang du trykker på det grønne flueben, skriver programmet `data/words_to_learn.csv` med de ord, du endnu ikke kan.
 - Næste start bruger den fil. Findes den ikke, bruger programmet hele ordlisten `data/ms-da.csv`.
 - For at starte forfra skal du slette `data/words_to_learn.csv`.
 - Det røde kryds ændrer aldrig filen.
 - Kendte ord forbliver kendte på alle niveauer. Niveauet begrænser kun, hvilke af de ord, du endnu ikke kender, der kommer frem, og filen beholder altid alle ord, du ikke kender, også dem uden for niveauet.
 - Denne liste har 1000 ord, så "1000 words" og "All words" giver de samme kort.
 ## Filformat
 Begge filer er UTF-8-tekst med ét kort pr. linje og cellerne adskilt af semikolon. Første linje har de to sprogkoder.

 | `--no-speech` | Udtal ikke det malajiske ord, selv om tilvalget til tale er installeret |
 ## Brug et andet sprogpar
 Læg en fil med samme format i datamappen og kald den `ms-da.csv`, eller ret `VOCABULARY_FILE_NAME` og `LANGUAGE_NAMES` i `src/flash_card/constants.py`. Kodene i overskriften vises som sprognavne fra `LANGUAGE_NAMES`; ukendte koder vises med store bogstaver.

 # Penggunaan
 🌐 [English](Usage) · [Dansk](Usage-da) · **Bahasa Malaysia**
 ## Berlatih dengan kad
 1. Mulakan program dengan `python -m flash_card`.
 2. Pilih tahap: **100 words**, **1000 words** atau **All words**. Senarai perkataan disusun daripada perkataan paling kerap kepada paling jarang, jadi tahap 100 ialah 100 perkataan paling kerap.
 3. Kad menunjukkan satu perkataan Melayu. Cuba ingat terjemahan Denmarknya.
 4. Selepas tiga saat kad terbalik dan menunjukkan terjemahan.
 5. Tekan tanda semak hijau jika anda tahu perkataan itu, atau pangkah merah jika tidak.
 6. Satu perkataan rawak baharu daripada tahap itu muncul. Ulang.
 Perkataan yang anda tandakan sebagai diketahui dibuang dan tidak muncul lagi. Apabila tiada perkataan lagi pada tahap itu, kad menunjukkan "Nothing left to learn"; mulakan program semula dan pilih tahap yang lebih tinggi.
 ## Bar menu
 ![Tetingkap dengan bar menu](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/raw/branch/main/docs/images/screenshot-menu.png)
 | Menu | Perintah | Apa yang dilakukan |
 | --- | --- | --- |
 | File | Open... | Membuka senarai perkataan lain daripada fail CSV (baris pertama dengan dua kod bahasa, contohnya `en;da`). Kemajuan disimpan berasingan bagi setiap senarai |
 | File | Change level... | Menunjukkan pilihan tahap semula tanpa memulakan semula; perkataan yang diketahui kekal diketahui |
 | File | Reset word list... | Selepas pengesahan membuang kemajuan senarai yang dibuka, supaya semua perkataannya perlu dipelajari semula; fail senarai tidak diubah |
 | File | Exit | Menutup program |
 | About | Contact | Pengarang, Jens Tirsvad Nielsen, jurutera perisian; membuka halaman LinkedIn dalam pelayar anda |
 Kemajuan bagi `ms-da.csv` yang disertakan ialah `data/words_to_learn.csv`; senarai lain mendapat `data/words_to_learn_<nama>.csv`. Senarai yang dibuka tidak diingati selepas dimulakan semula.
 ## Kemajuan anda
 - Kali pertama anda menekan tanda semak hijau, program menulis `data/words_to_learn.csv` dengan perkataan yang anda belum tahu.
 - Permulaan seterusnya menggunakan fail itu. Jika ia tiada, program menggunakan senarai penuh `data/ms-da.csv`.
 - Untuk bermula semula, padam `data/words_to_learn.csv`.
 - Pangkah merah tidak pernah mengubah fail.
 - Perkataan yang diketahui kekal diketahui pada semua tahap. Tahap hanya mengehadkan perkataan yang belum anda ketahui yang muncul, dan fail sentiasa menyimpan semua perkataan yang anda belum tahu, termasuk yang di luar tahap.
 - Senarai ini mempunyai 1000 perkataan, jadi "1000 words" dan "All words" memberikan kad yang sama.
 ## Format fail
 Kedua-dua fail ialah teks UTF-8 dengan satu kad setiap baris dan sel dipisahkan oleh koma bertitik. Baris pertama mengandungi dua kod bahasa.
 ```text
 ms;da
 aku;mig
 yang;hvilke
 ```
 ## Pilihan
 | Pilihan | Maksud |
 | --- | --- |
 | `--data-dir <folder>` | Folder yang mengandungi `ms-da.csv` dan `words_to_learn.csv` (lalai: `data/` dalam repositori) |
 | `--level {100,1000,all}` | Mulakan pada tahap itu dan langkau skrin tahap |
 | `--no-speech` | Jangan sebut perkataan Melayu, walaupun tambahan suara dipasang |
 ## Gunakan pasangan bahasa lain
 Letakkan fail dengan format yang sama dalam folder data dan namakannya `ms-da.csv`, atau ubah `VOCABULARY_FILE_NAME` dan `LANGUAGE_NAMES` dalam `src/flash_card/constants.py`. Kod pada baris pertama dipaparkan sebagai nama bahasa daripada `LANGUAGE_NAMES`; kod yang tidak dikenali dipaparkan dengan huruf besar.
 ## Penyelesaian masalah
 | Masalah | Apa yang perlu dilakukan |
 | --- | --- |
 | `No module named tkinter` | Pasang Tkinter (`python3-tk` pada Debian dan Ubuntu) |
 | Tiada bunyi | Pasang tambahan `speech` dan periksa rangkaian; program mencatat amaran apabila penyebutan gagal |
 | Program berhenti dengan mesej tentang fail | Fail CSV tidak betul; mesej menyebut fail dan barisnya. Fail tidak ditulis ganti |

 # Usage
 🌐 **English** · [Dansk](Usage-da) · [Bahasa Malaysia](Usage-ms)
 ## Study the cards
 1. Start the program with `python -m flash_card`.
 2. Choose a level: **100 words**, **1000 words** or **All words**. The word list is ordered from the most to the least frequent word, so level 100 is the 100 most frequent words.
 3. A card shows a Malay word. Try to remember its Danish translation.
 4. After three seconds the card turns over and shows the translation.
 5. Press the green tick when you knew the word, or the red cross when you did not.
 6. A new random word of the level appears. Repeat.
 A word you marked as known is removed and does not come up again. When no word of the level is left, the card says "Nothing left to learn"; restart the program and choose a higher level.
 ## The menu bar
 ![The window with the menu bar](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/031-flash-card/raw/branch/main/docs/images/screenshot-menu.png)
 | Menu | Command | What it does |
 | --- | --- | --- |
 | File | Open... | Opens another word list from a CSV file (header with two language codes, for example `en;da`). Progress is kept apart for each list |
 | File | Change level... | Shows the level choice again without a restart; known words stay known |
 | File | Reset word list... | After a confirmation removes the progress of the open list, so all its words are to learn again; the list file is not changed |
 | File | Exit | Closes the program |
 | About | Contact | The author, Jens Tirsvad Nielsen, Software engineer; opens the LinkedIn page in your browser |
 The progress of the delivered `ms-da.csv` is `data/words_to_learn.csv`; another list gets `data/words_to_learn_<name>.csv`. The opened list is not remembered after a restart.
 ## Your progress
 - The first time you press the green tick, the program writes `data/words_to_learn.csv` with the words you do not know yet.
 - The next start uses that file. If it does not exist, the program uses the full word list `data/ms-da.csv`.
 - To start again, delete `data/words_to_learn.csv`.
 - The red cross never changes the file.
 - Known words stay known at every level. The level only limits which of the words you do not know yet come up, and the file always keeps every word you do not know, also those outside the level.
 - This list has 1000 words, so "1000 words" and "All words" give the same cards.
 ## File format
 Both files are UTF-8 text with one card per line and the cells separated by a semicolon. The first line holds the two language codes.
 ```text
 ms;da
 aku;mig
 yang;hvilke
 ```
 ## Options
 | Option | Meaning |
 | --- | --- |
 | `--data-dir <folder>` | Folder that holds `ms-da.csv` and `words_to_learn.csv` (default: `data/` of the repository) |
 | `--level {100,1000,all}` | Start at that level and skip the level screen |
 | `--no-speech` | Do not speak the Malay word, even when the speech extra is installed |
 ## Use another language pair
 Put a file with the same format in the data folder and name it `ms-da.csv`, or change `VOCABULARY_FILE_NAME` and `LANGUAGE_NAMES` in `src/flash_card/constants.py`. The header codes are shown as language names from `LANGUAGE_NAMES`; unknown codes are shown in upper case.
 ## Troubleshooting
 | Problem | What to do |
 | --- | --- |
 | `No module named tkinter` | Install Tkinter (`python3-tk` on Debian and Ubuntu) |
 | No sound | Install the `speech` extra and check the network; the program logs a warning when speaking fails |
 | The program stops with a message about the file | The CSV file is malformed; the message names the file and the line. The file is not overwritten |
