+#### 🧠 In-Memory Buffer
+
+Keep a rolling, queryable window of recent log entries in memory — perfect for diagnostics dashboards, post-mortems, or exposing recent logs through a debug endpoint without writing them to disk:
+
+```typescript
+import { SmartlogDestinationBuffer } from '@push.rocks/smartlog/destination-buffer';
+
+// Default buffer holds 2000 entries (circular: oldest entries are evicted)
+const buffer = new SmartlogDestinationBuffer({ maxEntries: 5000 });
+logger.addLogDestination(buffer);
+
+// Query recent entries (chronological order, oldest-first)
+const recent = buffer.getEntries({ limit: 100 });
+
+// Filter by level (single or multiple)
+const errorsOnly = buffer.getEntries({ level: 'error' });
+const warningsAndErrors = buffer.getEntries({ level: ['warn', 'error'] });
+
+// Filter by message content (case-insensitive search)
+const dbErrors = buffer.getEntries({ search: 'database' });
+
+// Filter by timestamp (entries since a given moment)
+const sinceLastMinute = buffer.getEntries({ since: Date.now() - 60_000 });
+
+// Pagination — limit + offset (offset counts back from the newest entry)
+const page = buffer.getEntries({ limit: 50, offset: 100 });
+
+// Inspect or clear the buffer
+console.log(buffer.getEntryCount()); // current number of stored entries
+buffer.clear();
+```
+
+Use it together with an HTTP endpoint to surface live, in-process logs for debugging:
+
+```typescript
+app.get('/_debug/logs', (req, res) => {
+  const level = req.query.level as any;
+  const search = req.query.search as string;
+  res.json(buffer.getEntries({ level, search, limit: 200 }));
+});
+```
