ONLINESTATUS98%GATEWAY12sLAST ACT``` Although an API endpoint is declared, it is never queried. Instead, the displayed telemetry is generated randomly: ```javascript // CONFIG: Change this to your API endpoint const API_ENDPOINT = 'http://192.168.31.19:8000/healthz'; function initGraph() { const container = document.getElementById('performanceGraph'); const values = [65, 45, 78, 52, 88, 42, 71, 55, 83, 47, 76, 58]; container.innerHTML = values.map((v, i) => `` ).join(''); } function updateData() { const cpu = Math.floor(Math.random() * 40) + 30; const mem = Math.floor(Math.random() * 30) + 50; const net = Math.floor(Math.random() * 40) + 10; document.getElementById('cpuValue').textContent = cpu + '%'; d ...[truncated 3207 chars]45msRESP TIME- Remediation

controller.abort(), 5000); try { const response = await fetch(API_ENDPOINT, { method: 'GET', headers: { 'Accept': 'application/json' }, signal: controller.signal, cache: 'no-store' }); if (!response.ok) { throw new Error(`Health endpoint returned ${response.status}`); } const data = await response.json(); // Validate data before updating the interface. } catch (error) { showUnavailableState(error); } finally { clearTimeout(timeout); } } ``` 2. Validate the response schema and types before using any returned fields. Reject missing, malformed, non-finite, or out-of-range values. 3. Default all operational fields to `UNKNOWN` rather than `ONLINE`. Change the display to `OFFLINE`, `UNREACHABLE`, or `INVALID RESPONSE` when the request fails, times out, or returns malformed data. 4. Derive system and gateway status exclusively from verified API data. Do not preserve a healthy status after communication has failed. 5. Remove random values, hard-coded service statuses, and sample activity records from production mode. If demonstration data is retained, label the entire interface prominently as `DEMO DATA — NOT LIVE`. 6. Display the timestamp of the last successful API response and mark data as stale after an appropriate interval. 7. Prefer a configurable same-origin HTTPS endpoint instead of the hard-coded plaintext private-network URL. This reduces mixed-content failures and avoids exposing health data to network interception. 8. If the health endpoint contains sensitive operational informatio ...[truncated 559 chars]
