 ## Open Issues
 
-### Backend Architecture
+---
 
-- **Replace the single shared SQLite connection.**
+### TASK-001 — WorldMap: filter companion table by selected country (server-side)
-  - Current startup code opens one `aiosqlite.Connection` and reuses it for every request.
-  - This should be replaced with either a connection pool or request-scoped connections to avoid concurrency and locking issues.
-  - Update request dependencies, application lifecycle, and tests to use the new pattern.
 
-- **Refactor dependency wiring and shared resource management.**
+**Status:** Done  
-  - Remove hidden module-level import coupling between routers, services, and shared utilities.
+**Priority:** Medium  
-  - Introduce explicit factories or providers for shared resources such as DB, HTTP client session, scheduler, and settings.
+**Domain:** Full-stack (backend + frontend)  
-  - Ensure routers depend on injected providers rather than global state or dynamic imports.
+**References:** `Docs/Features.md §4`, `Docs/Web-Development.md`
 
-- **Harden fail2ban integration.**
+#### Background
-  - Remove the `sys.path` hack that locates `fail2ban-master` at runtime.
-  - Replace it with a deterministic packaging or configuration model so the backend does not depend on repository layout.
-  - Refactor `Fail2BanClient` so concurrency control is instance-based and not backed by hidden module globals.
 
-- **Improve startup / setup guard behavior.**
+The `GET /api/dashboard/bans/by-country` endpoint always returns the **200 most recent** ban rows in `bans` (constant `_MAX_COMPANION_BANS = 200` in `backend/app/services/ban_service.py`). `MapPage.tsx` stores a `selectedCountry` state and filters the returned rows client-side via `visibleBans`. This means the companion table can only show the fraction of a country's bans that fall within the global top-200 window. If the selected time range has, say, 1 500 bans and 300 are from China, but China's bans are not all in the top 200 overall, the table will silently display fewer than 300 rows.
-  - Convert `SetupRedirectMiddleware` from an on-demand DB check into a startup/initialisation guard where possible.
-  - Cache setup completion in a safe way and provide an explicit invalidation path if the application state changes.
-  - Reduce middleware responsibility and avoid DB access during normal request dispatch.
 
-- **Make deployment configuration explicit.**
+When a country is selected the companion table **must** return the complete set of bans for that country so the user sees an accurate picture.
-  - Move hard-coded environment assumptions such as CORS origins into settings.
-  - Ensure `fail2ban_socket`, `fail2ban_config_dir`, and startup commands are fully configurable via `Settings`.
-  - Document production-ready defaults separately from development defaults.
 
-### Reliability and Resilience
+#### Desired behaviour
 
-- **Add backend lifecycle tests for resource cleanup.**
+- No country selected → companion table shows the 200 most recent bans across all countries (existing behaviour, no change).
-  - Verify startup opens and initialises DB, HTTP session, scheduler, and geo cache correctly.
+- Country selected → the server returns **all** ban entries for that country in the selected time window; no client-side row-count cap applies.
-  - Verify shutdown closes those resources cleanly.
+- Deselecting a country (clicking the same country again, or the "Clear filter" button) reverts to the default 200-row unfiltered view.
+- The existing `visibleBans` client-side filter in `MapPage.tsx` can remain as a defensive guard but must not be the only filter.
 
-- **Add concurrency/regression coverage for DB and fail2ban socket use.**
+#### Implementation steps
-  - Add tests that simulate multiple concurrent requests using the same DB dependency.
-  - Add tests around fail2ban socket retries, protocol errors, and rate limiting.
 
-- **Improve state caching and invalidation.**
+1. **Backend — router** (`backend/app/routers/dashboard.py`)
-  - Add tests for session cache invalidation on logout.
+   - Add `country_code: str | None = Query(default=None, description="ISO alpha-2 country code to filter companion rows.")` to `get_bans_by_country`.
-  - Add tests for setup completion caching so stale state is never served.
+   - Pass it to `ban_service.bans_by_country(..., country_code=country_code)`.
 
-### Backend Feature Work
+2. **Backend — service** (`backend/app/services/ban_service.py`)
+   - Add `country_code: str | None = None` keyword argument to `bans_by_country`.
+   - After `geo_map` is built (existing geo-resolution step), collect IPs whose resolved country matches `country_code`.
+   - For the **fail2ban source**: call `fail2ban_db_repo.get_currently_banned` with `ip_filter=matched_ips` and no `limit` (remove the `_MAX_COMPANION_BANS` cap for filtered queries).
+   - For the **archive source**: filter `all_rows` to those whose IP is in `matched_ips` and return all of them (skip the `page_size=_MAX_COMPANION_BANS` call).
+   - When `country_code` is `None`, behaviour is identical to today.
 
-- **Document and implement backend-safe environment-driven CORS.**
+3. **Backend — repository** (`backend/app/repositories/fail2ban_db_repo.py`)
-  - Add support for production and local development origins through configuration.
+   - Add `ip_filter: list[str] | None = None` to `get_currently_banned`.
-  - Avoid a hardcoded Vite origin in the core app factory.
+   - When provided and non-empty, append `AND ip IN ({placeholders})` to the SQL `WHERE` clause, parameterised safely (never interpolated as a string).
 
-- **Centralise scheduler job registration.**
+4. **Backend — repository (archive)** (`backend/app/repositories/history_archive_repo.py`)
-  - Refactor APScheduler registration so background tasks are registered through a common lifecycle helper.
+   - Similarly add optional `ip_filter` to the archive companion-rows query used from `bans_by_country`.
-  - Ensure jobs can be discovered, replaced, and tested without requiring implicit `app.state` side effects.
 
-- **Strengthen fail2ban error handling and reporting.**
+5. **Frontend — API client** (`frontend/src/api/map.ts`)
-  - Standardise `502` responses for connection/protocol failures across all endpoints.
+   - Add optional `countryCode?: string` parameter to `fetchBansByCountry`.
-  - Add structured logging for retries and fatal socket failures.
+   - When set, append `country_code=<value>` to the query string.
-  - Ensure the UI can distinguish offline fail2ban from internal backend failures.
 
-- **Improve documentation of backend responsibilities.**
+6. **Frontend — hook** (`frontend/src/hooks/useMapData.ts`)
-  - Keep `Docs/Tasks.md` aligned with the backend architecture review.
+   - Add `countryCode?: string` to the function signature.
-  - Add references to the backend modules, resource lifecycle, and dependency model in the documentation.
+   - Include it in the `useCallback` dependency array and pass it to `fetchBansByCountry`.
 
-### Priority Execution Plan
+7. **Frontend — page** (`frontend/src/pages/MapPage.tsx`)
+   - Pass `selectedCountry ?? undefined` as `countryCode` to `useMapData`.
+   - The hook's effect will re-fetch automatically when `selectedCountry` changes; the existing `useEffect` that resets `page` to 1 already covers this.
 
-1. Fix the global SQLite connection pattern and tests.
+#### Testing guidance
-2. Refactor dependency injection / explicit shared resources.
+
-3. Harden fail2ban client concurrency and packaging.
+- Select a country that has > 200 bans in the chosen time window; confirm the companion table shows more than the previous cap would allow.
-4. Convert setup guard to a safer startup-driven model.
+- With no country selected, confirm only 200 rows are returned (no regression).
-5. Add deployment-safe configuration and production-ready CORS.
+- Deselect the country; confirm the unfiltered 200-row view is restored.
-6. Add lifecycle and concurrency regression tests.
+- Test with the archive source as well as the fail2ban live source.
+- Verify the `ip_filter` SQL clause is parameterised and cannot be injected.
