+
+---
+
+## 1. `main.py` — Router Registration
+
+### Status: ⚠️ FAIL
+
+### Critical Issues
+
+**C-01: `card_router.router` double-prefix path conflict**
+- `card_router.py` defines `router = APIRouter(prefix="/api/cards", ...)`
+- `main.py` mounts it with `app.include_router(card_router.router, prefix="/api", ...)`
+- **Result:** All card search endpoints resolve to `/api/api/cards/...` instead of `/api/cards/...`
+- **Impact:** All card search, card-by-id, sets, types, rarities, and suggest endpoints are broken.
+
+### Warnings
+
+**W-01: `interactions.router` has internal prefix `/interactions` but mounted without prefix**
+- `interactions.py`: `router = APIRouter(prefix="/interactions", ...)`
+- `main.py`: `app.include_router(interactions.router, ...)` (no prefix)
+- **Result:** Paths resolve correctly to `/interactions/...` — this is intentional and works, but is inconsistent with `card_router` pattern.
+
+**W-02: `refresh.router` has internal prefix `/mtgjson` but mounted without prefix**
+- `refresh.py`: `router = APIRouter(prefix="/mtgjson", ...)`
+- `main.py`: `app.include_router(refresh.router)` (no prefix)
+- **Result:** Paths resolve correctly to `/mtgjson/...` — same pattern as W-01.
+
+### Info
+
+**I-01:** `games.router` is imported as `games` (the package) and mounted with `prefix="/games"`. The actual router is at `app.routers.games.router.router`. This works because FastAPI resolves `games.router` to the `router` attribute of the `games` module.
+
+**I-02:** All routers use consistent `Depends(get_db)` or `Depends(mtg_get_db)` for database sessions.
+
+---
+
+## 2. `auth.py` — Authentication Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| POST | `/auth/login` | `LoginResponse` | ❌ (public) |
+| POST | `/auth/refresh` | `TokenResponse` | ❌ (token-based) |
+| POST | `/auth/register` | `UserResponse` | ❌ (public) |
+| GET | `/auth/me` | `UserResponse` | ✅ (token query param) |
+
+### Warnings
+
+**W-01: `get_current_user` endpoint uses query parameter for token**
+- The `/auth/me` endpoint expects `token: str` as a query parameter rather than a Bearer token in the Authorization header.
+- This is non-standard for JWT authentication and inconsistent with how `get_current_user` dependency works in other routers (which reads from the Authorization header).
+- **Recommendation:** Consider using `Authorization: Bearer <token>` header for consistency, or document this as a deliberate design choice.
+
+### Info
+
+- Login endpoint correctly omits `get_current_user` dependency (public endpoint).
+- All response models match their schema definitions in `schemas.py`.
+- Proper HTTP status codes: 401 for invalid credentials, 403 for disabled/banned accounts, 409 for duplicate username/email.
+
+---
+
+## 3. `users.py` — User Management Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/users/{user_id}` | `UserResponse` | ✅ |
+| PATCH | `/users/{user_id}` | `UserResponse` | ✅ (self-only) |
+| POST | `/users/{user_id}/ban` | dict | ✅ (admin/judge) |
+| POST | `/users/{user_id}/unban` | dict | ✅ (admin/judge) |
+
+### Info
+
+- Self-update protection is correctly implemented (users can only update their own profile).
+- Ban/unban endpoints properly check for admin/judge privileges.
+- `UserUpdate` schema fields are correctly mapped to model fields.
+- Password hashing is applied only when `new_password` is provided.
+
+---
+
+## 4. `decks.py` — Deck Management Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/decks/` | `UserDeckListResponse` | ✅ |
+| POST | `/decks/` | `UserDeckResponse` | ✅ |
+| GET | `/decks/{deck_id}` | `UserDeckResponse` | ✅ |
+| PATCH | `/decks/{deck_id}` | `UserDeckResponse` | ✅ |
+| DELETE | `/decks/{deck_id}` | `MessageResponse` | ✅ |
+| POST | `/decks/{deck_id}/finalize` | `DeckFinalizeResponse` | ✅ |
+| POST | `/decks/{deck_id}/cards` | `DeckCardResponse` | ✅ |
+| GET | `/decks/{deck_id}/cards` | `DeckCardListResponse` | ✅ |
+| PATCH | `/decks/{deck_id}/cards/{card_id}` | `DeckCardResponse` | ✅ |
+| DELETE | `/decks/{deck_id}/cards/{card_id}` | `MessageResponse` | ✅ |
+| GET | `/decks/precedents` | `PrecedentListResponse` | ✅ |
+| POST | `/decks/precedents` | `PrecedentResponse` | ✅ |
+| GET | `/decks/precedents/{precedent_id}` | `PrecedentResponse` | ✅ |
+| POST | `/decks/precedents/{precedent_id}/use` | dict | ✅ |
+| POST | `/decks/search/cards` | `CardSearchResponse` | ✅ |
+| GET | `/decks/{deck_id}/suggestions` | `SuggestionListResponse` | ✅ |
+| POST | `/decks/{deck_id}/suggestions` | `SuggestionResponse` | ✅ |
+
+### Warnings
+
+**W-01: `DeckPrecedent` imported from `app.models.user_deck`**
+- `DeckPrecedent` and `DeckPrecedentCard` are imported from `app.models.user_deck` but may belong in a different model file. Verify model placement is correct.
+
+### Info
+
+- FINAL deck protection is consistently enforced across all mutating endpoints.
+- Owner verification is applied on all deck-access endpoints.
+- Pagination is consistently implemented with `page`/`page_size` query parameters.
+- Card search uses `ilike` for case-insensitive matching across name, type_line, and mana_cost.
+- Precedent cloning correctly copies cards from precedent to new deck.
+
+---
+
+## 5. `card_import.py` — Card Import Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| POST | `/api/v1/card-import/import` | `CardImportResponse` | ✅ |
+| GET | `/api/v1/card-import/import/{import_id}/status` | `CardImportStatusResponse` | ✅ |
+| GET | `/api/v1/card-import/import/{import_id}/results` | `CardImportSummary` | ✅ |
+| POST | `/api/v1/card-import/import/{import_id}/confirm` | `MessageResponse` | ✅ |
+| GET | `/api/v1/card-import/user/cards` | `List[Dict]` | ✅ |
+| DELETE | `/api/v1/card-import/user/cards/{card_import_id}` | `MessageResponse` | ✅ |
+| GET | `/api/v1/card-import/user/decks` | `List[Dict]` | ✅ |
+
+### Critical Issues
+
+**C-01: `get_user_cards` endpoint has no response model**
+- Returns `List[Dict[str, Any]]` instead of a proper Pydantic response model.
+- Inconsistent with all other endpoints in the project which use typed response models.
+- **Impact:** OpenAPI documentation will show untyped response, and clients cannot rely on response structure.
+- **Recommendation:** Create a `UserCardResponse` schema and use it as `response_model`.
+
+### Warnings
+
+**W-01: Temp file cleanup not guaranteed**
+- `upload_card_import` creates a temp file with `tempfile.NamedTemporaryFile` but only wraps parsing in a try/except. If the file is read successfully but processing fails afterward, the temp file is never cleaned up.
+- **Recommendation:** Use `with tempfile.NamedTemporaryFile(...)` as a context manager, or add a `finally` block to delete the temp file.
+
+### Info
+
+- File type validation correctly restricts to xlsx, csv, json, ods.
+- Owner verification is applied on all import-related endpoints.
+- Import confirmation correctly checks for duplicates before adding to collection.
+
+---
+
+## 6. `card_router.py` — Card Search Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/api/cards/search` | `CardSearchResponse` | ❌ |
+| GET | `/api/cards/{card_id}` | `CardResponse` | ❌ |
+| GET | `/api/cards/sets` | `List[SetResponse]` | ❌ |
+| GET | `/api/cards/types` | `List[CardTypeResponse]` | ❌ |
+| GET | `/api/cards/rarities` | `List[str]` | ❌ |
+| GET | `/api/cards/suggest` | `List[Dict]` | ❌ |
+
+### Critical Issues
+
+**C-01: Double-prefix path conflict (see main.py C-01)**
+- Router has `prefix="/api/cards"` and is mounted at `prefix="/api"`.
+- All endpoints resolve to `/api/api/cards/...` — **all 6 endpoints are broken.**
+
+**C-02: `suggest_cards_endpoint` queries wrong database**
+- Uses `mtg_get_db` dependency (MTG card database) but checks `UserDeck` model which lives in the main application database.
+- The `UserDeck` query will fail because it's running against the MTG database which doesn't have the `user_decks` table.
+- **Impact:** Card suggestion endpoint will always return 404 or crash.
+- **Recommendation:** Use `get_db` (main database) for the `UserDeck` check, or query the MTG database for deck-related data if that's the intended design.
+
+### Warnings
+
+**W-01: No authentication on card search endpoints**
+- All 6 endpoints are publicly accessible without authentication.
+- This may be intentional for a card search feature, but should be documented.
+- No rate limiting is applied.
+
+### Info
+
+- Redis caching is consistently applied across all endpoints with appropriate TTLs.
+- Response format uses `{"cached": bool, "results": ...}` pattern — non-standard but consistent within this router.
+
+---
+
+## 7. `interactions.py` — Card Interactions Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/interactions/synergies/{card_id}` | dict | ❌ |
+| GET | `/interactions/counters/{card_id}` | dict | ❌ |
+| GET | `/interactions/evolutions/{card_id}` | dict | ❌ |
+| GET | `/interactions/recommend/{card_id}` | dict | ❌ |
+| GET | `/interactions/search/synergies` | dict | ❌ |
+| GET | `/interactions/search/counters` | dict | ❌ |
+| GET | `/interactions/search/evolutions` | dict | ❌ |
+| GET | `/interactions/stats/{card_id}` | dict | ❌ |
+
+### Critical Issues
+
+**C-01: All endpoints return untyped `dict` responses**
+- None of the 8 endpoints use `response_model` — they all return raw dictionaries.
+- This means OpenAPI/Swagger docs will show no response schema, and clients have no type safety.
+- **Recommendation:** Create response schemas (e.g., `SynergyResponse`, `CounterResponse`, etc.) and apply them.
+
+### Warnings
+
+**W-01: SQL injection risk with f-string query construction**
+- Multiple endpoints build SQL WHERE clauses using f-strings: `f"WHERE {where_clause}"`.
+- While parameter binding is used for values, the column/condition construction is not sanitized.
+- If any user-controlled input reaches the `synergy_type`, `counter_type`, or `evolution_type` query parameters, it could be injected into the WHERE clause.
+- **Current mitigation:** Query parameters are validated by FastAPI type checking, but column names in `ORDER BY` and table references are not parameterized.
+- **Recommendation:** Use a whitelist for filter values or use SQLAlchemy core expressions instead of raw SQL.
+
+**W-02: No authentication on any endpoint**
+- All 8 endpoints are publicly accessible.
+- No rate limiting is applied.
+- **Recommendation:** Document as intentional public API, or add authentication if these are sensitive interaction data.
+
+### Info
+
+- Redis caching is consistently applied with appropriate TTLs (10min–30min).
+- Pagination is included in search endpoints.
+- The `stats/{card_id}` endpoint returns zeros for missing cards rather than 404 — reasonable design choice.
+
+---
+
+## 8. `games/router.py` — Game Management Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/games/` | `List[GameResponse]` | ✅ |
+| POST | `/games/` | `GameResponse` | ✅ |
+| GET | `/games/{game_id}` | `GameResponse` | ✅ |
+| POST | `/games/{game_id}/join` | dict | ✅ |
+| POST | `/games/{game_id}/leave` | dict |
+| POST | `/games/{game_id}/start` | dict |
+| POST | `/games/{game_id}/end` | dict |
+
+### Critical Issues
+
+**C-01: `list_games` and `get_game` are stub/mock implementations**
+- `list_games` always returns `[]` without querying any database.
+- `get_game` returns a hardcoded mock response regardless of `game_id`.
+- **Impact:** These endpoints are non-functional. Any client relying on them will get incorrect data.
+- **Recommendation:** Either implement proper database queries or mark these as TODO with appropriate error responses.
+
+### Warnings
+
+**W-01: Join/Leave/Start/End endpoints have no response model**
+- All 4 mutation endpoints return raw dicts instead of typed response models.
+- **Recommendation:** Create a `GameActionResponse` schema.
+
+**W-02: `get_game` does not verify game ownership or existence**
+- Returns a mock response for any `game_id` without checking if the game actually exists.
+- No authorization check beyond the general `get_current_user` dependency.
+- **Recommendation:** Implement proper game lookup and ownership verification.
+
+### Info
+
+- `create_game` correctly verifies user existence before creating.
+- `GameCreate` schema is properly used for the create endpoint.
+- The router imports `User` model but only for verification in `create_game`.
+
+---
+
+## 9. `admin.py` — Admin Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/admin/users` | `List[dict]` | ✅ (admin/judge) |
+| GET | `/admin/bans` | `List[BanResponse]` | ✅ (admin/judge) |
+| POST | `/admin/bans` | `BanResponse` | ✅ (admin/judge) |
+| POST | `/admin/bans/{ban_id}/unban` | dict | ✅ (admin/judge) |
+| GET | `/admin/logs` | `List[dict]` | ✅ (admin/judge) |
+| POST | `/admin/audit` | dict | ✅ (admin/judge) |
+
+### Info
+
+- All endpoints correctly enforce admin/judge privilege checks.
+- Ban creation properly links to user and sets moderator name.
+- Unban operation correctly updates both Ban and User records.
+- Audit logging captures admin actions with target user and details.
+
+---
+
+## 10. `rooms.py` — Room Management Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/rooms/` | `List[RoomResponse]` | ✅ |
+| GET | `/rooms/{room_id}` | `RoomResponse` | ✅ |
+| POST | `/rooms/` | dict | ✅ (admin/judge) |
+| PATCH | `/rooms/{room_id}` | dict | ✅ (admin/judge) |
+| DELETE | `/rooms/{room_id}` | dict | ✅ (admin/judge) |
+
+### Info
+
+- CRUD operations are complete for rooms.
+- Admin-only write operations are properly enforced.
+- Room name uniqueness is checked before creation.
+- `RoomResponse` schema matches model fields.
+
+---
+
+## 11. `refresh.py` — MTGJSON Data Refresh Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| POST | `/mtgjson/refresh` | dict | ✅ (admin) |
+| GET | `/mtgjson/status` | dict | ✅ (admin) |
+| POST | `/mtgjson/verify` | dict | ✅ (admin) |
+
+### Critical Issues
+
+**C-01: `/status` and `/verify` endpoints missing `db` dependency**
+- `get_refresh_status` and `verify_files` do not accept `db: AsyncSession = Depends(get_db)`.
+- If `MTGJSONManager.get_health_status()` or `verify_files()` need database access, these endpoints will fail.
+- **Impact:** Potential runtime error if the manager methods require a database session.
+- **Recommendation:** Add `db` dependency or verify that the manager methods don't need it.
+
+### Warnings
+
+**W-01: No response model on any endpoint**
+- All 3 endpoints return raw dicts without `response_model`.
+- **Recommendation:** Create response schemas for consistency.
+
+---
+
+## 12. `user_data.py` — User Data Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/api/v1/user-data/sessions/me` | `List[SessionCleanupResponse]` | ✅ |
+| DELETE | `/api/v1/user-data/sessions/cleanup` | `MessageResponse` | ✅ |

+| PATCH | `/api/v1/user-data/preferences` | `UserPreferenceResponse` | ✅ |
+| GET | `/api/v1/user-data/activity` | `ActivityLogListResponse` | ✅ |
+
+### Critical Issues
+
+**C-01: `create_deck_version` verifies user against `User` table instead of deck ownership**
+- The endpoint checks `select(User).where(User.id == user_id)` which will always succeed for any authenticated user.
+- It does NOT verify that the user owns the deck being versioned.
+- **Impact:** Any authenticated user can create versions for any deck.
+- **Recommendation:** Add a deck ownership check (e.g., query the deck's `user_id` field).
+
+**C-02: `get_game_replays` has ambiguous join condition**
+- `conditions.append(ReplayPlayer.user_id == user_id)` — the `user_id` column exists in both `GameReplay` (via ReplayPlayer join) and `ReplayPlayer`.
+- SQLAlchemy may raise `AmbiguousForeignKeysError` or join against the wrong table.
+- **Recommendation:** Use explicit table references: `ReplayPlayer.user_id == user_id` is correct, but the join should be explicit: `stmt = stmt.join(ReplayPlayer)`.
+
+**C-03: `update_user_statistics` has no user ownership verification**
+- The endpoint accepts `user_id` as a query parameter and updates statistics for any user.
+- Any authenticated user can modify another user's statistics.
+- **Recommendation:** Either restrict to self-update or add admin check.
+
+### Warnings
+
+**W-01: `get_deck_versions` returns wrong response structure**
+- `DeckVersionListResponse` expects `versions: List[DeckVersionResponse]`, `total: int`, `page: int`, `page_size: int`, `total_pages: int`.
+- But the endpoint wraps the list in `[SessionCleanupResponse(...)]` for sessions — wait, that's the sessions endpoint.
+- Actually, `get_deck_versions` correctly returns `DeckVersionListResponse` with proper pagination fields. **This is correct.**
+
+**W-02: `get_user_groups` and `get_user_networks` add `member_count` to response**
+- `GroupResponse` and `NetworkResponse` schemas include `member_count: int = 0` as a default, so this is actually valid.
+- **No issue here** — the schemas already account for this field.
+
+**W-03: `send_group_message` manually constructs response instead of using `model_validate`**
+- Inconsistent with other endpoints that use `model_validate`.
+- **Recommendation:** Use `GroupChatMessageResponse.model_validate(message)` for consistency, or keep manual construction if sender_username needs special handling.
+
+**W-04: `add_replay_player` and `add_network_member` return raw dicts**
+- These endpoints return `{"message": ..., "player_id": ...}` instead of typed response models.
+- **Recommendation:** Create response schemas.
+
+**W-05: `get_replay_players` returns `List[dict]` instead of typed response**
+- **Recommendation:** Create a `ReplayPlayerResponse` schema.
+
+### Info
+
+- Extensive CRUD coverage across sessions, decks, replays, outcomes, statistics, collection, wishlist, groups, networks, preferences, and activity logs.
+- Owner verification is consistently applied on collection, wishlist, and preference endpoints.
+- Group and network admin/owner checks are properly implemented.
+- Pagination is consistently applied across list endpoints.
+- `get_user_groups` correctly filters to groups where the user is a member using subquery.

+
+## Recommendations (Priority Order)
+
+### P0 — Fix Immediately (Blocking)
+
+1. **Fix `card_router.py` double-prefix**: Remove `prefix="/api/cards"` from the router definition in `card_router.py` since `main.py` already mounts it at `prefix="/api"`. This breaks all 6 card search endpoints.
+
+2. **Fix `card_router.py` cross-database query**: Change `suggest_cards_endpoint` to use `get_db` instead of `mtg_get_db` for the `UserDeck` check.
+
+3. **Fix `user_data.py` `create_deck_version` ownership check**: Add deck ownership verification before allowing version creation.
+
+4. **Fix `user_data.py` `update_user_statistics` authorization**: Add ownership or admin check.
+
+### P1 — Fix Soon (Significant Impact)
+
+5. **Add response models to all endpoints returning `dict`**: Create proper Pydantic schemas for `card_import.py`, `interactions.py`, `games/router.py`, `refresh.py`, and `user_data.py` endpoints that currently return raw dicts.
+
+6. **Fix `games/router.py` stub implementations**: Either implement proper database queries for `list_games` and `get_game`, or return appropriate error responses.
+
+7. **Fix `refresh.py` missing `db` dependency**: Add `db` parameter to `/status` and `/verify` endpoints.
+
+8. **Fix `interactions.py` SQL injection risk**: Use parameterized queries or whitelists for filter values.
+
+### P2 — Improve (Nice to Have)
+
+9. **Standardize prefix pattern**: Decide whether routers should define their own prefixes or rely on `main.py` mounting. Apply consistently.
+
+10. **Add authentication to public endpoints**: Document why `card_router.py` and `interactions.py` are public, or add rate limiting.
+
+11. **Fix `auth.py` token retrieval**: Consider using Bearer token header instead of query parameter for `/auth/me`.
+
+12. **Add temp file cleanup in `card_import.py`**: Use context manager or finally block.

+
+---
+
+## 1. `schemas.py` — ⚠️ FAIL
+
+**Models covered:** User, DecklistFile, DecklistFolder, Room, Ban, MtgCardMirror, DeckCardLink
+
+### Critical Issues
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| C1 | `UserResponse` | **Missing fields from User model** | `avatar_bmp`, `salt`, `ban_ends`, `vip_expiry` are in the `User` model but absent from the response schema. `password_hash` is correctly excluded (security), but the others should be present or explicitly excluded. |
+
+### Warnings
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| W1 | `schemas.py` (all) | **Pydantic v1 `class Config` used** | All schemas use `class Config: from_attributes = True` (Pydantic v1 style). Other schema files use Pydantic v2 `model_config = ConfigDict(from_attributes=True)`. Inconsistent. |
+| W2 | `GameResponse` | **Fields not in Room model** | `with_password`, `max_players`, `player_count`, `started` are not columns in the `Room` model. These appear to be computed/derived fields but are not documented. If computed, they should be `Field(default=...)` with defaults. |
+
+### Info
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| I1 | `BanResponse` | **Missing `ip_address` field** | The `Ban` model has `ip_address` (String(45)) but `BanResponse` does not include it. |
+
+---
+
+## 2. `user_data_schemas.py` — ⚠️ FAIL
+
+**Models covered:** UserSession, DeckVersion, GameReplay, ReplayPlayer, GameOutcome, UserStatistics, UserCardCollection, CardWishlist, UserGroup, GroupMember, GroupChatMessage, UserNetwork, NetworkMember, UserPreference, UserActivityLog
+
+### Critical Issues
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| C1 | `GameReplayResponse` | **Missing `players` field** | The `GameReplay` model has a `players` relationship (List[ReplayPlayer]). The schema has `players: List[Dict[str, Any]] = []` which is a generic placeholder, not a typed schema. Should define a `ReplayPlayerResponse` schema. |
+
+### Warnings
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| W1 | `DeckVersionStatus` enum | **Values don't match model** | Enum has `DRAFT`, `FINAL`, `ARCHIVED`. The `DeckVersion` model has `status` column with `server_default="DRAFT"` and `String(20)`. The `user_deck_schemas.py` `DeckStatus` enum has only `DRAFT`/`FINAL`. The `ARCHIVED` value has no model support. |
+| W2 | `GameReplayCreate` / `GameReplayUpdate` | **`format` is a Python keyword** | Using `format` as a field name shadows the built-in `format()` function. Should use `game_format` or `deck_format` instead. |
+| W3 | `GroupMember` model | **Missing `joined_at` in GroupMemberCreate** | `GroupMemberCreate` has `user_id` and `role` but the model also has `joined_at` (auto-set by server_default, so OK for create). Not a bug, but worth noting. |
+
+### Info
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| I1 | `UserSessionResponse` | **Missing `session_token_hash`** | Model has `session_token_hash` but it's correctly excluded from response (security). Document this exclusion. |
+| I2 | `GroupResponse` | **`member_count` and `is_member` are computed** | Not in the `UserGroup` model. These are computed fields. Should have `Field(default=0)` / `Field(default=False)` with documentation. |
+| I3 | `NetworkResponse` | **Missing `updated_at`** | The `UserNetwork` model does NOT have `updated_at`, so this is actually correct. No issue. |
+
+---
+
+## 3. `user_deck_schemas.py` — ⚠️ FAIL
+
+**Models covered:** UserDeck, UserDeckCard, DeckPrecedent, CardSuggestion
+
+### Critical Issues
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| C1 | `UserDeckCreate` | **Missing `status` field** | The `UserDeck` model has `status` (String(20), default="DRAFT") as a required column. `UserDeckCreate` does not include `status`. If the default is relied upon, this is acceptable, but it should be explicit. |
+
+### Warnings
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| W1 | `CardSearchResponse` | **Uses `List[Dict[str, Any]]` instead of typed schema** | Should use `List[CardResponse]` (from `card_search_schemas.py`) for type safety. |
+| W2 | `PrecedentResponse` | **Missing `updated_at` field** | The `DeckPrecedent` model has `updated_at` (DateTime) but `PrecedentResponse` does not include it. |
+| W3 | `DeckStatus` enum | **Conflicts with `user_data_schemas.py` `DeckVersionStatus`** | Both enums have `DRAFT`/`FINAL` values but different names and different files. The `DeckVersion` model in `user_data.py` uses `DeckVersionStatus` from `user_data_schemas.py`, while `UserDeck` model uses string values directly. This creates confusion. |
+
+### Info
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| I1 | `DeckCardResponse` | **Missing `updated_at`** | The `UserDeckCard` model does NOT have `updated_at`, so this is correct. No issue. |
+| I2 | `SuggestionResponse` | **`card_name` is computed** | Not in the `CardSuggestion` model. Should be documented as a computed field with `Field(default="")`. |
+
+---
+
+## 4. `card_import_schemas.py` — ⚠️ FAIL
+
+**Models covered:** UserCardImport, CardImportBatch
+
+### Warnings
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| W1 | `CardImportStatusResponse` | **Missing fields vs CardImportBatch model** | Missing `batch_id`, `status`, `total_cards`, `matched_cards`, `unmatched_cards`, `error_message`. The `CardImportBatch` model has all these columns. |
+| W2 | `CardImportResponse` | **Missing `batch_id` and `status`** | The `CardImportBatch` model has `batch_id` (id) and `status` fields. Response only has `message`, `card_count`, `card_names`, `imported_at`. |
+
+### Info
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| I1 | `CardMatchResult.match_type` | **Inconsistent with `card_search_schemas.py`** | This file uses `'exact'`, `'fuzzy'`, `'partial'`. The `card_search_schemas.py` version uses `'exact'`, `'high_confidence'`, `'low_confidence'`. |
+| I2 | `ErrorResponse` | **Duplicate of generic schemas** | Same as `MessageResponse`/`CountResponse` duplicates found in other files. |
+
+---
+
+## 5. `user_card_collection.py` — ⚠️ FAIL
+
+**Models covered:** UserCardCollection, CardWishlist
+
+### Warnings
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| W1 | `CardCollectionListResponse` | **Missing pagination fields** | Has `cards`, `total`, `page`, `page_size`, `total_pages` — this is actually correct and matches the pattern. No issue here. The warning is that `WishlistListResponse` is missing `page`/`page_size`/`total_pages` while `CardCollectionListResponse` has them. Inconsistent pagination. |
+
+### Info
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| I1 | `CardCondition` / `AcquisitionMethod` enums | **Not validated against model** | The model stores these as `String(20)` and `String(50)` respectively. The enums provide validation at the schema layer, which is good. However, the `CardCollectionResponse` serializes them as plain `str`, losing the enum type info. |
+| I2 | `WishlistResponse` | **Missing `updated_at`** | The `CardWishlist` model does NOT have `updated_at`, so this is correct. No issue. |
+
+---
+
+## 6. `card_search_schemas.py` — ⚠️ FAIL
+
+**Models covered:** MtgCard, MtgSet, CardImportBatch (partial)
+
+### Critical Issues
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| C1 | `CardResponse` | **Missing 8 fields from MtgCard model** | Missing: `artist`, `flavor_text`, `numbers`, `image`, `card_parts`, `keywords`, `legalities`, `identifiers` (as typed). The `MtgCard` model has all these columns. |
+| C2 | `SetResponse` | **Missing 10 fields from MtgSet model** | Missing: `type`, `base_set_size`, `total_size`, `is_foil_only`, `is_non_foil_only`, `digital`, `icon_svg_url`, `parent_code`, `mtgo_code`, `image`. The `MtgSet` model has all these columns. |
+
+### Warnings
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| W1 | `CardImportStatusResponse` | **Missing fields vs CardImportBatch** | Missing `batch_id`, `status`, `total_cards`, `matched_cards`, `unmatched_cards`, `error_message`. |
+| W2 | `CardMatchResult.match_type` | **Inconsistent with `card_import_schemas.py`** | Uses `'exact'`, `'high_confidence'`, `'low_confidence'` vs `'exact'`, `'fuzzy'`, `'partial'` in `card_import_schemas.py`. |
+| W3 | `CardImportResponse` | **Missing `file_type` and `file_size`** | The `CardImportBatch` model has `file_type` and `file_size` columns not reflected in this response. |
+
+### Info
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| I1 | `CardSearchResponse` | **Uses `List[Dict[str, Any]]`** | Should use `List[CardResponse]` for type safety. |
+| I2 | `CardTypeResponse` | **Trivial schema** | Only has `type: str`. May be unnecessary or could be merged. |
+
+---
+
+## 7. `__init__.py` — ⚠️ FAIL
+
+### Critical Issues
+
+| # | Schema | Issue | Detail |
+|---|---|---|---|
+| C1 | `__init__.py` | **No imports — schemas not exported** | The file only contains `# Schemas package` comment. No schemas are imported or re-exported. Consumers must know the exact file path for each schema. Should at minimum export commonly used schemas. |
+
+---
+
+## Cross-File Issues
+
+### Duplicate Generic Schemas (Found in 5 files)
+
+The following generic schemas are defined identically in multiple files:
+
+| Schema | Files |
+|---|---|
+| `MessageResponse` | `user_data_schemas.py`, `user_deck_schemas.py`, `card_import_schemas.py`, `user_card_collection.py`, `card_search_schemas.py` |
+| `CountResponse` | `user_data_schemas.py`, `user_deck_schemas.py`, `card_import_schemas.py`, `user_card_collection.py`, `card_search_schemas.py` |
+| `ErrorResponse` | `card_import_schemas.py`, `card_search_schemas.py` |
+| `ErrorDetail` | `user_data_schemas.py`, `user_card_collection.py` |
+
+**Recommendation:** Create a `app/schemas/common.py` with these shared schemas and import from there.
+
+### Models Without Any Schema Coverage
+
+| Model | File |
+|---|---|
+| `UserCardImport` | `user_card_import.py` |
+| `UserCardImportRecord` | `user_card_import_record.py` |
+| `ReplayPlayer` | `user_data.py` |
+| `GroupMember` (response) | `user_data.py` |
+| `NetworkMember` (response) | `user_data.py` |
+| `DeckPrecedentCard` | `user_deck.py` |
+
+### Pydantic v1 vs v2 Inconsistency
+
+- `schemas.py`: Uses `class Config: from_attributes = True` (v1 style)
+- All other files: Use Pydantic v2 `BaseModel` (no explicit `model_config`, relying on defaults or not setting `from_attributes`)
+
+**Recommendation:** Standardize on Pydantic v2 `model_config = ConfigDict(from_attributes=True)` in a common base or in each file.
+
+---
+
+## Recommendations (Priority Order)
+
+1. **Fix `__init__.py`** — Add schema exports so consumers can import from `app.schemas`
+2. **Create `app/schemas/common.py`** — Extract duplicate `MessageResponse`, `CountResponse`, `ErrorResponse`, `ErrorDetail`
+3. **Fix `CardResponse` and `SetResponse`** in `card_search_schemas.py` — Add all missing model fields
+4. **Fix `CardImportStatusResponse`** in both `card_import_schemas.py` and `card_search_schemas.py` — Add missing fields
+5. **Standardize Pydantic v2** — Use `model_config = ConfigDict(from_attributes=True)` consistently
+6. **Resolve enum conflicts** — `DeckVersionStatus` vs `DeckStatus`, `CardMatchResult.match_type` values
+7. **Add `ReplayPlayerResponse`** — Replace `List[Dict[str, Any]]` in `GameReplayResponse`
+8. **Add missing schemas** — `UserCardImport`, `UserCardImportRecord`, `DeckPrecedentCard`
+9. **Fix `format` field name** in `GameReplayCreate`/`Update` — Rename to `game_format`
+10. **Add `updated_at`** to `PrecedentResponse` and `UserDeckCreate` (status field)

+# Phase 5: Service Layer Test Report
+
+**Date:** 2024-01-15  
+**Scope:** All service files in `app/services/`  
+**Status:** FAIL (Critical issues found)
+
+---
+
+## Executive Summary
+
+The service layer has **12 critical issues**, **8 warnings**, and **5 informational findings**. The most significant problems are:
+
+1. **`deck_manager.py` is not used by the deck router** - The router implements all CRUD operations inline, duplicating logic
+2. **`card_search_service.py` and `deck_suggestion_service.py` reference non-existent `MtgCard.colors` field** - Will cause AttributeError at runtime
+3. **`import_batch_processor.py` stores non-JSON-serializable tuples** - Will cause serialization errors
+4. **`game_server.py` lacks permission validation** - Security vulnerability
+

+
+**Issues:**
+- **WARNING:** **NOT USED by deck router** - Router implements all CRUD operations inline
+- **WARNING:** `clone_precedent` doesn't check for duplicate deck names
+- **INFO:** Service exists but is orphaned
+
+**Notes:**
+- Correctly uses `UserDeck`, `UserDeckCard`, `DeckPrecedent` from `user_deck.py`
+- Good business logic (FINAL status checks, empty deck validation)
+- Proper authorization checks (user_id matching)
+- **Recommendation:** Either use this service in the router or remove it

+- **WARNING:** `import_all_printings_psql` uses `subprocess.run` to call `psql` command
+  - Security risk (command injection if paths are user-controlled)
+  - Not ideal for async code
+  - **Recommendation:** Use SQLAlchemy or asyncpg for PSQL import
+
+**Notes:**
+- Standalone utility, not called by routers
+- Good table definitions
+- Proper data import workflow
+
+---
+
+## Cross-Service Integration Issues
+
+### 1. Duplicate Function Names
+
+**Issue:** `card_database.py` and `card_mirror_service.py` both define `get_card_statistics`
+
+**Impact:** Confusion about which function to call. They return different statistics:
+- `card_database.get_card_statistics`: Total cards, sets, by rarity, by type
+- `card_mirror_service.get_card_statistics`: Total mirrored cards, by rarity, by type
+
+**Recommendation:** Rename one or both functions for clarity
+
+---
+
+### 2. Orphaned Service
+
+**Issue:** `deck_manager.py` exists but is not used by the deck router
+
+**Impact:** Duplicated logic, maintenance burden
+
+**Recommendation:** Either:
+1. Refactor deck router to use `DeckManager` service
+2. Remove `deck_manager.py` if not needed
+
+---
+
+### 3. Missing Field References
+
+**Issue:** `card_search_service.py` and `deck_suggestion_service.py` reference `MtgCard.colors` which doesn't exist
+
+**Impact:** Runtime `AttributeError`
+
+**Recommendation:** Either:
+1. Add `colors` field to `MtgCard` model
+2. Remove color filtering from search/suggestion logic
+3. Use a different field for color-based filtering
+

+## Router-Service Mapping
+
+| Router | Service | Status |
+|--------|---------|--------|
+| `users.py` | N/A (inline) | ✅ |
+| `auth.py` | N/A (inline) | ✅ |
+| `admin.py` | N/A (inline) | ✅ |
+| `rooms.py` | N/A (inline) | ✅ |
+| `card_router.py` | `card_search_service`, `deck_suggestion_service` | ❌ (missing colors field) |
+| `decks.py` | N/A (inline, duplicates `deck_manager`) | ⚠️ |
+| `card_import.py` | `file_parser`, `import_batch_processor`, `fuzzy_card_matcher` | ❌ (JSON serialization) |
+| `refresh.py` | `mtgjson_manager` | ✅ |
+| `ws.py` | `game_server` | ⚠️ (permission validation) |
+| N/A | `card_database`, `card_mirror_service`, `deck_parser`, `mtgjson_downloader`, `mtgjson_loader`, `mtgjson_uploader` | ✅ (standalone) |
+
+---
+
+## Recommendations
+
+### Critical (Must Fix)
+
+1. **Fix `MtgCard.colors` reference** in `card_search_service.py` and `deck_suggestion_service.py`
+   - Add field to model OR remove color filtering
+
+2. **Fix JSON serialization** in `import_batch_processor.py`
+   - Convert tuples to lists before storing in `match_results`
+
+3. **Add permission validation** to `game_server.py` `process_game_command`
+   - Check player privileges before executing commands
+
+### Warnings (Should Fix)
+
+4. **Resolve orphaned `deck_manager.py`**
+   - Use it in deck router OR remove it
+
+5. **Complete `sync_mirrors_from_mtg_cards`** in `card_mirror_service.py`
+   - Implement the sync logic or mark as deprecated
+
+6. **Fix `import_all_printings_psql`** in `mtgjson_uploader.py`
+   - Use async database operations instead of subprocess
+
+7. **Rename duplicate `get_card_statistics`** functions
+   - Clarify which service they belong to
+
+### Informational
+
+8. **Consider using `DeckManager`** in deck router for consistency
+9. **Add input validation** to game commands
+10. **Document service dependencies** in `__init__.py`
+
