+## 🏎️ Request Hedging
+
+Request hedging sends multiple concurrent or sequential requests to reduce latency by racing against slow responses. This is particularly effective for high-latency scenarios where P99 tail latencies impact user experience.
+
+### When to Use Hedging
+
+**Use hedging when:**
+- High P99 latencies are impacting user experience
+- Idempotent read operations (GET, HEAD, OPTIONS)
+- Server-side variability is high (cloud, microservices)
+- Cost of duplicate requests is acceptable
+
+**Don't use hedging when:**
+- Non-idempotent operations (POST, PUT, DELETE)
+- Bandwidth is severely constrained
+- Server capacity is limited
+- Operations have side effects
+
+### Basic Race Policy
+
+Race policy sends multiple concurrent requests and uses the first successful response:
+
+```js
+const api = createLuminara({
+  hedging: {
+    policy: 'race',
+    hedgeDelay: 1000,     // Wait 1s before sending hedge
+    maxHedges: 2          // Up to 2 hedge requests
+  }
+});
+
+// Timeline:
+// T+0ms:    Primary request sent
+// T+1000ms: Hedge #1 sent (if primary not complete)
+// T+2000ms: Hedge #2 sent (if neither complete)
+// First successful response wins, others cancelled
+await api.get('/api/data');
+```
+
+### Cancel-and-Retry Policy
+
+Cancel-and-retry policy cancels slow requests and retries sequentially:
+
+```js
+const api = createLuminara({
+  hedging: {
+    policy: 'cancel-and-retry',
+    hedgeDelay: 1500,     // Wait 1.5s before cancelling
+    maxHedges: 2          // Up to 2 hedge attempts
+  }
+});
+
+// Timeline:
+// T+0ms:    Primary request sent
+// T+1500ms: Cancel primary, send hedge #1
+// T+3000ms: Cancel hedge #1, send hedge #2
+// Only one request active at a time
+await api.get('/api/data');
+```
+
+### Exponential Backoff & Jitter
+
+Increase hedge delays exponentially with randomization to prevent thundering herd:
+
+```js
+const api = createLuminara({
+  hedging: {
+    policy: 'race',
+    hedgeDelay: 500,            // Base delay: 500ms
+    maxHedges: 3,
+    exponentialBackoff: true,   // Enable exponential backoff
+    backoffMultiplier: 2,       // 2x each time
+    jitter: true,               // Add randomness
+    jitterRange: 0.3            // ±30% jitter
+  }
+});
+
+// Hedge timing with backoff:
+// - Primary:  0ms
+// - Hedge 1:  ~500ms  (500 ±30%)
+// - Hedge 2:  ~1000ms (1000 ±30%)
+// - Hedge 3:  ~2000ms (2000 ±30%)
+```
+
+### HTTP Method Whitelist
+
+By default, only idempotent methods are hedged:
+
+```js
+// Default whitelist: ['GET', 'HEAD', 'OPTIONS']
+
+const api = createLuminara({
+  hedging: {
+    policy: 'race',
+    hedgeDelay: 1000,
+    maxHedges: 2,
+    includeHttpMethods: ['GET', 'HEAD', 'OPTIONS', 'POST']  // Custom whitelist
+  }
+});
+
+await api.get('/users');     // ✅ Hedged (in whitelist)
+await api.post('/data', {}); // ✅ Hedged (added to whitelist)
+await api.put('/users/1', {}); // ❌ Not hedged (not in whitelist)
+```
+
+### Per-Request Configuration (Bidirectional Override)
+
+Override hedging settings for specific requests:
+
+```js
+// Scenario 1: Global enabled → disable per-request
+const client = createLuminara({
+  hedging: { policy: 'race', hedgeDelay: 1000 }
+});
+
+await client.get('/critical', {
+  hedging: { enabled: false }  // Disable for this request
+});
+
+// Scenario 2: Global disabled → enable per-request
+const client2 = createLuminara({ /* no hedging */ });
+
+await client2.get('/slow-endpoint', {
+  hedging: {                     // Enable for this request
+    policy: 'race',
+    hedgeDelay: 500,
+    maxHedges: 1
+  }
+});
+```
+
+### Server Rotation
+
+Distribute hedge requests across multiple servers:
+
+```js
+const api = createLuminara({
+  hedging: {
+    policy: 'race',
+    hedgeDelay: 1000,
+    maxHedges: 2,
+    servers: [
+      'https://api1.example.com',
+      'https://api2.example.com',
+      'https://api3.example.com'
+    ]
+  }
+});
+
+// Each hedge uses a different server:
+// - Primary: api1.example.com/data
+// - Hedge 1: api2.example.com/data
+// - Hedge 2: api3.example.com/data
+```
+
+### Hedging vs Retry
+
+**Hedging** and **Retry** serve different purposes and can be used together:
+
+| Feature | Hedging | Retry |
+|---------|---------|-------|
+| **Purpose** | Reduce latency | Handle failures |
+| **Trigger** | Slow response | Error response |
+| **Requests** | Concurrent/Sequential proactive | Sequential reactive |
+| **Cost** | Higher (multiple requests) | Lower (on error only) |
+| **Use Case** | P99 optimization | Reliability |
+
+```js
+// Combined: Hedging for latency + Retry for reliability
+const api = createLuminara({
+  retry: false,  // Disable retry (can use false or 0)
+  hedging: {
+    policy: 'race',
+    hedgeDelay: 1000,
+    maxHedges: 1
+  }
+});
+```
+
+### Configuration Options
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `enabled` | `boolean` | implicit | Explicit enable/disable (implicit if config present) |
+| `policy` | `string` | `'race'` | `'race'` or `'cancel-and-retry'` |
+| `hedgeDelay` | `number` | - | Base delay before hedge (ms) |
+| `maxHedges` | `number` | `1` | Maximum hedge requests |
+| `exponentialBackoff` | `boolean` | `false` | Enable exponential backoff |
+| `backoffMultiplier` | `number` | `2` | Backoff multiplier |
+| `jitter` | `boolean` | `false` | Add randomness to delays |
+| `jitterRange` | `number` | `0.3` | Jitter range (±30%) |
+| `includeHttpMethods` | `string[]` | `['GET', 'HEAD', 'OPTIONS']` | Hedged HTTP methods |
+| `servers` | `string[]` | `[]` | Server rotation URLs |
+
+### Performance Implications
+
+**Bandwidth:** Hedging increases bandwidth usage by sending multiple requests. For a `maxHedges: 2` configuration:
+- Best case: 1 request (primary succeeds quickly)
+- Worst case: 3 requests (primary + 2 hedges)
+- Average: ~1.5-2 requests depending on latency
+
+**Latency Reduction:** Typical P99 improvements:
+- Race policy: 30-60% reduction in tail latencies
+- Cancel-and-retry: 20-40% reduction with lower bandwidth cost

 ## 🚦 Rate Limiting
 
 Luminara's rate limiting system uses a **token bucket algorithm** with flexible scoping to control request flow and prevent API abuse.
