-### TASK-QUALITY-05 — `console.warn` in `MapPage` Provides No User Feedback for Threshold Errors
-
-**Where found**
-`frontend/src/pages/MapPage.tsx` lines ~148–151:
-```ts
-useEffect(() => {
-  if (mapThresholdError) {
-    console.warn("Failed to load map color thresholds:", mapThresholdError);
-  }
-}, [mapThresholdError]);
-```
-When the threshold fetch fails the map silently falls back to hardcoded defaults. The user has no indication that their custom thresholds are not being applied.
-
-**Goal**
-Replace the `console.warn` with a small inline `MessageBar` or tooltip near the map legend that indicates thresholds could not be loaded and defaults are in use. The `console.warn` should be removed from production-facing code.
-
-**Possible traps and issues**
-- The fallback behaviour (using hardcoded defaults) is correct and the map should still render. The notification should be non-blocking (not a modal or full-page error).
-- If the threshold fetch failing is expected in certain deployment configurations (e.g. feature not configured), an info-level message rather than a warning may be more appropriate.
-
-**Docs changes needed**
-None required.
-
-**Why this is needed**
-`console.warn` is invisible to end users. If a custom threshold configuration is silently not applied, the map colour coding may be misleading with no indication of why.
