## What this tab shows

The Compliance tab performs real-time checks against two international regulations — IMO D-2 and USCG — using the most recent telemetry record. It also tracks treatment effectiveness, maintenance record status, and certification validity in one consolidated view.

Data sources:

* `/api/telemetry/latest` — for all live compliance values
* `/api/events?limit=20` — for the audit trail

## Summary stat row

| Stat                  | Description                                                   |
| --------------------- | ------------------------------------------------------------- |
| Compliance Rate       | Percentage of the five compliance items that show COMPLIANT   |
| Active Certifications | Total number of compliance items being tracked                |
| Latest Check          | Timestamp of the most recent telemetry record used for checks |
| Issues                | Count of items showing WARNING or NON-COMPLIANT               |

## The five compliance items

| # | Item                    | Logic                       | Compliant threshold           |
| - | ----------------------- | --------------------------- | ----------------------------- |
| 1 | IMO D-2 Standard        | `UVR_INTENSITY >= 252`      | ≥ 252 W/m²                    |
| 2 | USCG Type Approval      | `UVR_INTENSITY >= 530`      | ≥ 530 W/m²                    |
| 3 | Treatment Effectiveness | `AVG_LAMP_EFFICIENCY >= 70` | ≥ 70% average lamp efficiency |
| 4 | Maintenance Records     | `FAILED_LAMP_COUNT === 0`   | Zero failed lamps             |
| 5 | Certification Validity  | Static expiry date check    | Certificate not expired       |

### Status indicators

| Icon              | Status        | Meaning                                               |
| ----------------- | ------------- | ----------------------------------------------------- |
| Green circle (✓)  | COMPLIANT     | Threshold met                                         |
| Yellow circle (!) | WARNING       | Marginal zone — threshold approached or partially met |
| Red circle (✗)    | NON-COMPLIANT | Threshold not met — action required                   |

## Treatment Effectiveness panel

Three horizontal progress bars show how far current values are from their compliance thresholds:

| Bar                 | Calculation           | Full =                  |
| ------------------- | --------------------- | ----------------------- |
| IMO D-2 Compliance  | `UVR_INTENSITY / 252` | 100% at 252 W/m²        |
| USCG Compliance     | `UVR_INTENSITY / 530` | 100% at 530 W/m²        |
| Avg Lamp Efficiency | `AVG_LAMP_EFFICIENCY` | 100% at 100% efficiency |

Each bar shows the actual numeric value below it. Use these bars to monitor proximity to threshold limits — a bar at 80% of fill means there is a 20% margin before non-compliance.

## Audit Trail

<Frame caption="System event audit trail showing the last 8 process events">
  <img src="https://mintcdn.com/metaweaveconsultant/Yh8TWLsifrpzxzbC/images/compliance/audit-trail.png?fit=max&auto=format&n=Yh8TWLsifrpzxzbC&q=85&s=c51f979cf08ca255e71c7a7838030a01" alt="Audit trail panel listing PROCESS_START, PROCESS_STOP, and ALARM_TRIGGERED events with timestamps" width="1440" height="900" data-path="images/compliance/audit-trail.png" />
</Frame>

The Audit Trail panel shows the last 8 system events in reverse chronological order. Each entry displays:

* **Timestamp** — UTC datetime of the event
* **Event type and description** — human-readable summary
* **Result** — PASS for process start/stop events, ALERT for alarm events

| Event type       | Displayed result |
| ---------------- | ---------------- |
| PROCESS\_START   | PASS             |
| PROCESS\_STOP    | PASS             |
| ALARM\_TRIGGERED | ALERT            |

## Important limitation

<Warning>
  The Compliance tab performs **real-time checks on the most recent telemetry record only**. It does not query a stored compliance log or historical compliance record. For official record-keeping and regulatory submissions, use the [Data Export tab](/product/data-export-tab) to download complete timestamped telemetry covering the full voyage period.
</Warning>
