Deadline Alerts Reference
Deadline Alerts Reference
This reference documents the dispatch-deadline alert pipeline used by SellerOps Watcher.
Trigger Definitions
- T-24:
dispatch_by_at - 24 hours - T-12:
dispatch_by_at - 12 hours - T-4:
dispatch_by_at - 4 hours
The alert runner executes every minute and checks due windows against current time.
Priority and Escalation
| Alert | Priority | Escalation Role |
|---|---|---|
| T-24 | 1 | Planning window |
| T-12 | 2 | High urgency warning |
| T-4 | 3 | Critical final warning |
If multiple stages are already due, SellerOps sends the most urgent due stage first (T-4 > T-12 > T-24).
Channels
- Watcher: email delivery for all three stages.
- Defender routing (when enabled): optional Slack routing and quiet-hours controls.
Quiet Hours
Quiet-hours evaluation is part of Defender routing logic. T-4 bypasses quiet-hours suppression. For suppressed windows, baseline email remains active while extra non-critical channels are suppressed.
Duplicate Prevention
Per-order stage dedupe uses:
t24_sent_att12_sent_att4_sent_at
Order Status Eligibility
Dispatch alerts are processed for open statuses:
AWAITING_SHIPMENTAWAITING_COLLECTIONPARTIALLY_SHIPPING
Status aliases are normalized before eligibility checks. Terminal/non-applicable statuses are excluded from alerts.
