+<script lang="ts">
 import { log } from "$lib/cot-logger";
 import { fetchApi } from "$lib/api";
-import { page } from "$app/stores";
 
-let { jobId } = $props();

-async function loadJob() {
-    log("JobDetail.loadJob", "REASON", "Fetch job details", { jobId });
+async function loadJob(): Promise<void> {
+    log("JobDetail", "REASON", "Fetch job details", { jobId });
 
     try {
         const resp = await fetchApi(`/api/jobs/${jobId}`);
         if (!resp.ok) throw new Error(`Status ${resp.status}`);
 
         const data = await resp.json();
-        log("JobDetail.loadJob", "REFLECT", "Job details loaded",
+        log("JobDetail", "REFLECT", "Job details loaded",
             { rows: data.records?.length });
         return data;
-    } catch (e) {
-        log("JobDetail.loadJob", "EXPLORE", "Failed to load job",
-            { jobId }, error = e.message);
+    } catch (e: unknown) {
+        log("JobDetail", "EXPLORE", "Failed to load job",
+            { jobId }, e instanceof Error ? e.message : "Unknown");
         throw e;
     }
 }
 </script>
 ```
 
+### trace_id Propagation
+
+The trace ID is set automatically when the backend returns it. Call `setTraceId(id)` manually if needed:
+
+```typescript
+import { setTraceId } from "$lib/cot-logger";
+import { requestApi } from "$lib/api";
+
+const res = await requestApi("/api/endpoint");
+if (res.trace_id) setTraceId(res.trace_id);
+```

 Frontend logging uses `log()` from `$lib/cot-logger`, emitting **JSON lines** per MolecularCoTLogging protocol.
 Import: `import { log } from "$lib/cot-logger";`
 
+The logger is a TypeScript module at `frontend/src/lib/cot-logger.ts` with full type support:
