Logging

Every failure and fault writes one structured event. A domain failure's event holds its code, kind, where it was raised, the path it travelled and its internal fields. No stack is captured for a domain failure.

{  "event": "failure.rejected",  "code": "quantity_unavailable",  "kind": "conflict",  "site": "domains/inventory/actions/reserve.jadpo:6",  "trace": ["action reserve", "action place_order", "route POST /orders"],  "request_id": "req_0b1e…",  "internal": {    "product_id": "0192f3a4-…",    "requested": 12  }}

Internal values made of text, which can hold names or email addresses, are logged as a keyed hash, so equal values still match up across events.
