Behaviour for host-owned audit export integrations.

Implement this behaviour when Scoria audit outbox events should be relayed to a SIEM, archive, compliance queue, or internal audit service. Scoria provides redacted envelope maps and reviewer-visible delivery evidence; the host app owns retention policy, export destination, credentials, and downstream compliance interpretation.

Configure a sink in the host app when audit export is part of your operating model:

config :scoria, :sre_audit_sink, MyApp.ScoriaAuditSink

Keep the default no-op sink for first-run adoption. See guides/ownership-boundary.md for the host-owned audit policy boundary; the reviewer verification suite in guides/reviewer-verification.md proves the runtime and dashboard boundary before optional audit export is wired.
