Webhook Events
Every event shares the same envelope. Each event type has its own page
covering what goes in data, when it fires, and — just as importantly — the cases where it is
deliberately not sent.
Read the Webhooks guide first for signature verification, retries, and idempotency.
New event types are added over time and are opt-in per subscription. Route on eventType and ignore
values you do not recognize; a subscription only receives the events it was provisioned for.

Every requirement.* event describes one requirement; they fire for DOCUMENT slots only.
Defined, not yet delivered
