# Export Notifications Schema Prep — PREP-EXPORT-NOTIFY-SCHEMA-OBS-52

Status: Draft (2025-11-20)
Owners: Notifications Guild · Exporter Service
Scope: Define notification envelope/payloads for export lifecycle events.

## Event types
- `export.started`, `export.completed`, `export.failed`.

## Envelope (proposed)
```json
{
  "type": "export.completed",
  "export_id": "...",
  "profile_id": "...",
  "tenant_id": "...",
  "artifact_counts": {"json": 2, "mirror": 1},
  "sha256": "...",
  "created_at": "2025-11-20T00:00:00Z"
}
```
- Deterministic key ordering; timestamps UTC.

## Open decisions
- Channel/transport (NATS vs Redis streams vs webhooks).
- Required retry/backoff policy and DLQ routing.

## Handoff
Use this prep doc for PREP-EXPORT-NOTIFY-SCHEMA-OBS-52; update once transport + DLQ policy are chosen.
