 - `std_file_system_tests.cpp` — `StdFileSystem` directly (`exists`, `isDirectory`, `ensureDirectory`, `readText`, `writeText`, `copyFile`, `remove`, `listDirectory`) under a unique `temp_directory_path()/ccm_std_fs_test_*` directory per case; scope matches the real-disk exception documented for preview-cache tests.
 - `pokemon_set_source_tests.cpp` — `PokemonSetSource::parseResponse` (api.pokemontcg.io/v2/sets shape — `data[].id`, `name`, `releaseDate` already in `YYYY/MM/DD`) + sort-by-release-date stability. Drives `fetchAll` via `FixedHttpClient` and asserts the public endpoint URL.
 - `pokemon_card_preview_source_tests.cpp` — `PokemonCardPreviewSource::buildSearchUrl` (percent-encoded `name:` / `set.id:` / `number:` triple, with collector-number `4/102` -> `4` normalization) + `parseResponse` (`data[0].images.large` with `images.small` fallback). Drives `fetchImageUrl` via `FixedHttpClient`.
+- `digibattle99_set_source_tests.cpp` — `DigiBattle99SetSource::parseResponse` derives unique packs from digimoncard.io search arrays, slugifies `Set.id`, applies curated release dates, and sorts chronologically. Drives `fetchAll` via `FixedHttpClient`.
+- `digibattle99_card_preview_source_tests.cpp` — CDN image URL from `setNo`, search URL encoding (`series`/`n`/`pack`/`card`), `parseImageUrlFromSearch` NotFound vs Transient, and auto-detect print variants. Drives `fetchImageUrl` / `detectPrintVariants` via `FixedHttpClient`.
 - `yugioh_set_source_tests.cpp` — `YuGiOhSetSource::parseResponse` for YGOPRODeck `cardsets.php` (`set_code`, `set_name`, `tcg_date`) including `YYYY-MM-DD` -> `YYYY/MM/DD` rewrite and chronological sort checks.
 - `yugioh_set_lookup_tests.cpp` — `lookupYuGiOhSetByShorthand` / helpers in `ccm/util/YuGiOhSetLookup.hpp` (trim, ASCII case-fold, exact `Set.id` match, not-found vs ambiguous).
-- `game_module_tests.cpp` — smoke tests that each concrete `IGameModule` (Magic / Pokemon / Yu-Gi-Oh) reports stable `id()`, `dirName()`, `displayName()`, and a non-null `cardPreviewSource()` when constructed with a noop `IHttpClient`.
+- `game_module_tests.cpp` — smoke tests that each concrete `IGameModule` (Magic / Pokemon / Yu-Gi-Oh / DigiBattle99) reports stable `id()`, `dirName()`, `displayName()`, and a non-null `cardPreviewSource()` when constructed with a noop `IHttpClient`.
 - `yugioh_card_preview_source_tests.cpp` — `YuGiOhCardPreviewSource` Yugipedia + YGOPRODeck unit coverage. Helper-level tests pin down `normalizeName` (whitespace + Yugipedia-policy punctuation stripping), `ygoRarityShortCode` + `rarityCodeFor` (CCM3 dialog rarity names → canonical short codes used by both the YGO overview table and Yugipedia filename generation; unknown rarity falls through), `extractSetCode` (`LOB-005` / `LOB-DE005` → `LOB`), `buildCandidateFilenames` (printed-edition first, EN/NA/EU/AU + png/jpg, rarity-less fallback round, empty list when slug or set code is missing), `buildYugipediaQueryUrl` (single `titles=File:A|File:B` batch, percent-encoded), and `parseYugipediaResponse` (returns the URL of the highest-priority filename that resolved, errors when every candidate is `missing`). End-to-end `fetchImageUrl` cases use a `RoutingHttpClient` to verify Yugipedia is queried first and the per-printing scan is returned when found, that empty/error Yugipedia responses fall through to the YGOPRODeck `card_images[0]` fallback, that the YGOPRODeck error is propagated when both upstreams fail, and that an empty `setNo` skips Yugipedia entirely. `parseFirstPrint` preferred-`set_name` lookup is also covered for the auto-detect path. `parsePrintVariants` includes synthetic scenarios aligned with the `yugioh_same_card_set_variant_tests` fixture (dual-rarity vs multi-code within one display set, duplicate suppression, and no merge across unrelated `set_name` rows when the picker label matches nothing).
 - `card_sorter_tests.cpp` — `sortMagicCards` / `sortPokemonCards` per-column behavior. Pin-down tests for `byField`-equivalent semantics: case-insensitive strings, chronological set sort via `set.releaseDate`, numeric `amount`, `false < true` boolean order, stable composition (sort by name then by set keeps inner-name order). Update this file whenever you add a new column / sort key.
 - `card_filter_tests.cpp` — `matchesMagicFilter` / `matchesPokemonFilter` / `matchesYuGiOhFilter` row-matcher behavior. Pin-down tests for `applyFilter`-equivalent semantics: case-insensitive substring match across `tableFields` valueKeys (name, set.name, language, condition, amount-as-string, note; Pokemon adds `setNo`; Yu-Gi-Oh adds `setNo` + `rarity`), boolean flag columns intentionally excluded, empty filter matches everything. Update this file whenever you add a new searchable column.
