Contract Pause & Suspension Mechanism

[DokaIzk]

Title: feat: implement contract pause/suspension for maintenance and incident response

Labels: enhancement operations
Complexity: medium
Branch: feat/contract-pause-suspension

---

Problem Context

When a contract is compromised or needs maintenance, operators need to temporarily pause indexing without deleting historical data. A pause/suspension mechanism enables rapid incident response.

---

Scope

Included:

• pause() method on TrackedContract: stops new events but keeps history
• suspension_reason field for audit trail
• Suspension scheduled: pause until, then auto-resume
• Webhook notification on pause/resume
• Admin UI to pause/resume

Not included:

• Automatic pause on error thresholds

---

Implementation Guidelines

Model updates:

class TrackedContract(models.Model):
    # ... existing fields ...
    is_paused = models.BooleanField(default=False)
    paused_at = models.DateTimeField(null=True)
    pause_reason = models.TextField(blank=True)
    resume_at = models.DateTimeField(null=True)

Constraints:

• Paused contracts don't receive new events
• Historical data remains queryable
• Auto-resume via Celery task

---

Acceptance Criteria

• pause() method stops indexing
• resume() method restarts indexing
• Pause reason logged
• Auto-resume at scheduled time
• Historical data still queryable
