# Know every changeis healthy in production.

Firetiger attaches a monitor to every pull request and watches the rollout across staging, canary, and production, returning one verdict per deploy: verified, regression detected, or inconclusive.

Firetiger monitoring a deployment

## A dedicated agent  
for every pull request

Open a PR. Firetiger reads the diff, builds a monitoring plan, and watches deployments rollout across every environment you care about.

You'll know within minutes whether the change broke anything, and more importantly, whether it's actually accomplishing its intended effect.

* Analyzes the PR diff  
Change Monitors understand what changed, what signals matter, and what normal should look like after.
* Watches the environments that matter  
Choose which environments to monitor: From staging to prod, tracked independently, with comparisons between them.
* Verifies intent, not just errors  
You opened a PR for a reason. Change Monitors verify the intended effect in production.

Batch line-item queries in checkout flow (FIRE-4821) #4821

Change Monitor complete — checkout flow is performing as expected.

All 3 monitored environments are healthy 15 minutes after rollout:

| Environment  | Deploy  | p99 latency  | Errors |
| ------------ | ------- | ------------ | ------ |
| staging      | 12m ago | 519ms −38.4% | 0      |
| canary       | 8m ago  | 527ms −37.4% | 0      |
| prod-us-east | 4m ago  | 531ms −37.0% | 0      |

Key observations:

* `db.query_count` per checkout dropped `14.2` → `1.02` avg — matches the batched query intent
* p99 latency reduced consistently across all 3 environments
* Error rate unchanged at `0.02%` — no regressions in request paths touched by the diff
* Cross-checked traffic on `/api/checkout` and `/api/cart` endpoints — volumes within normal bands

Continuing to watch `prod-us-east` for 24h before closing the monitor.
