Every change emits a typed, immutable event.

domain.entity.past-tense-verb naming. Outbox-relayed to Redis pub/sub, the datalake, and webhook subscribers. Replayable by id; never edited; never deleted.

What it does

Three things this surface gives you.

Outbox-relayed inside the same Postgres transaction as the entity write. No phantom events.
Webhook delivery is signed and replayable. Failed deliveries surface in the operator console.
Datalake export is per-tenant and includes the receipt chain alongside the event payload.

Subscribe via webhook

Worked example.

# Subscribe to inventory.reservation.created events
mutation SubscribeWebhook {
  subscribeWebhook(input: {
    targetUrl: "https://example.com/karmanflow",
    eventTypes: ["inventory.reservation.created"],
    signingSecretRef: "secrets://example-webhook"
  }) {
    subscriptionId
    receipt { commandId }
  }
}
