 - Prefer minimal, surgical edits; avoid large workflow rewrites unless requested.
 - Reusable workflows should declare explicit `workflow_call` inputs for required context (e.g., version, merge SHA).
 - Sonar coverage steps that use `gcovr` must exclude third-party build trees at discovery time with `--exclude-directories` (for example `build/_deps`) so gcov does not process dependency `.gcda` files.
+- The Sonar scan step passes `-Dsonar.coverage.exclusions=**/ui_wx/**,**/app/**` so the coverage quality gate reflects **`ccm_core_tests`** only (wx UI and the composition root are not executed under test). `sonar.sources` stays `core,ui_wx,app`.
+- The Sonar scan also sets `-Dsonar.cpd.exclusions=**/ui_wx/src/*GameView.cpp,**/ui_wx/src/*CardEditDialog.cpp,**/ui_wx/src/*SelectedCardPanel.cpp` so intentionally parallel wx per-game UI scaffolding does not dominate the duplication quality gate.
 - For Linux Sonar coverage jobs, keep compiler and gcov toolchain aligned; because `cmake/Toolchain.cmake` prefers Clang by default, set `-DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++` explicitly in the coverage configure step when using gcovr default `gcov`.
 - Keep `permissions` least-privilege:
   - reusable build workflows: `contents: read`

 - After modifying a domain type's fields or JSON layout you **must** update the matching round-trip test in `tests/domain_json_tests.cpp` and re-run tests.
 - After adding a new `.cpp` to `core/` or `ui_wx/` you **must** add it to that package's `CMakeLists.txt`. There is no glob.
 - After adding a new dependency you **must** verify its license is compatible with this repository's MIT license before merging.
-- After changing SonarQube coverage generation, keep dependency build outputs excluded at gcov discovery time (for example `gcovr --exclude-directories "build/_deps"`); output-only excludes are not enough for third-party `.gcda` files.
+- After changing SonarQube coverage generation, keep dependency build outputs excluded at gcov discovery time (for example `gcovr --exclude-directories "build/_deps"`); output-only excludes are not enough for third-party `.gcda` files. The Sonar scan uses `sonar.coverage.exclusions` for `**/ui_wx/**` and `**/app/**` so the coverage percentage matches the hermetic `ccm_core_tests` surface (`core/`); analyzed sources are unchanged for other Sonar metrics.
+- For new code, keep duplication to an absolute minimum: prefer extracting shared helpers/components instead of copy/paste so Sonar duplication stays comfortably below the quality gate.
+- For new code, add or update unit tests so behavior is covered and overall test coverage remains high.
+- For new code, run the local coverage workflow (`build-cov` + `gcovr` with `--filter "core/"`) and keep core line coverage at or above 80% before opening or updating a PR.
 - After adding a new game module you **must**: (1) extend `Game` enum + string mappings in `core/include/ccm/domain/Enums.hpp`, (2) register the module in `app/main.cpp`, (3) add a directory mapping in `app/main.cpp::dirNameForGame`, (4) implement an `IGameView` derived class (or `<Name>GameView`) and add it to `AppContext::gameViews` in the composition root.
 - After changing the per-game seams (`IGameModule`, `IGameView`, the `BaseCard*Panel` template hooks) you **must** update `docs/adding-a-new-game.md` so the canonical "add a new game" walkthrough stays in sync with the code.
 - After changing `formatTextForFs` or `parseIndexFromFilename` you **must** update `tests/fs_names_tests.cpp` — these functions exist to stay byte-compatible with the original Rust `util/fs.rs`.
 
+## Agent collaboration (Cursor / AI)

+- **Never** `git commit` or `git push` unless the user **explicitly** asked you to commit and/or push (e.g. “commit this”, “push to origin”). Preparing diffs and suggesting commands is fine; performing those Git writes without explicit instruction is not.
+- **Never** check out another branch **to change it** unless the user **explicitly** asked you to work on that branch. Temporarily checking out another branch **read-only** (inspect history, compare files, run `git show`) is fine without asking; switch back to the working branch before making edits unless instructed otherwise.

 ## Anti-patterns
 
 - Don't include `wx/...` headers from `core/` (breaks layering and tests will refuse to build).

Both fakes count `calls` so cache-hit assertions are precise. Pin-downs include: "module returning nullptr is silently skipped", the per-game `detectFirstPrint` / `detectPrintVariants` opt-in guards, and the LRU bytes cache (repeat `fetchPreviewBytes` for the same `(game, name, setId, setNo)` returns the cached payload without touching the source or HTTP; different cards get separate cache slots; transient errors are **not** cached so a flaky connection recovers; `fetchImageBytesByUrl` is keyed by URL and serves the per-game card-back fallback from the same LRU). Production `fetchAndCache` rejects empty HTTP bodies (not exercised by these fakes unless a test sets an empty `body` deliberately). The negative-cache behavior is also pinned down: a `NotFound` source error writes through to the persistent cache *and* short-circuits the next lookup (source not re-invoked); editing a lookup-relevant field invalidates the negative entry automatically; warm-restart (a fresh service over the same cache fake) honors a previously stored negative entry; and a later positive result for the same key replaces the negative entry.

 ## Conventions
 
 1. **Framework**: doctest. Each test file `#include <doctest/doctest.h>` and uses `TEST_SUITE("...")` + `TEST_CASE("...")`. Asserts: `CHECK`, `REQUIRE`, `CHECK_THROWS`.
-2. **No real I/O.** Everything goes through `ccm::testing::InMemoryFileSystem` or an inline test-local fake. If you need HTTP, write a fake `IHttpClient` like `FixedHttpClient` in `magic_set_source_tests.cpp`. **One narrow exception**: `local_preview_byte_cache_tests.cpp` exercises the real filesystem because `LocalPreviewByteCache` uses `std::filesystem` directly for size + mtime queries that the `IFileSystem` port deliberately does not expose. Those tests scope themselves to a unique temp directory and clean up unconditionally — do not extend the exception to other test files.
+2. **No real I/O.** Everything goes through `ccm::testing::InMemoryFileSystem` or an inline test-local fake. If you need HTTP, write a fake `IHttpClient` like `FixedHttpClient` in `magic_set_source_tests.cpp`. **Narrow exceptions** (unique temp dirs + RAII cleanup): `local_preview_byte_cache_tests.cpp` (mtime/size semantics tied to real `std::filesystem`) and `std_file_system_tests.cpp` (`StdFileSystem` integration). Do not add further real-disk suites without the same cleanup guarantees.
 3. **Fakes for narrow concerns stay in the test file** as anonymous-namespace classes (e.g. `RecordingImageStore`, `InMemoryRepo`). Promote a fake to `tests/fakes/` only when more than one test file needs it.
 4. **Path strings** in expectations must use forward slashes. The fake normalizes everything to `generic_string()`. Do not hard-code `\` separators.
 5. **Test names** describe behavior, not implementation. Prefer "missing file is created with defaults" over "test_init_no_file".

Per-game **Add/Edit** flows use `themeModalDialog(wxDialog*, Theme)` from `Theme.hpp` so `MagicGameView` / `PokemonGameView` / `YuGiOhGameView` share one path instead of duplicating palette wiring.
     - Do not use native `wxMessageBox` / `wxAboutBox` for app-facing flows that must match dark mode. Use themed popup helpers (or a custom themed `wxDialog`) so body/buttons stay in sync with the app palette.
     - Center popup dialogs on the app window (`CentreOnParent()`) so confirmations/info boxes open relative to the current app window.
