F1 policy writes and allow grants are human-surface only; F2 worker trust is
confined to the hook allowlist and unexpected exceptions become audited 500
error records; F4 external side effects release only for the same run and
argument hash; F6 the gate honours budget exhaustion; F8 only the gateway
can vouch for an empty process registry and failed receipts can be
superseded; F11/F12 receipt revision and unshipped card routes.

Stdlib per-tenant service: trusted-header identity (router/relay/worker,
constant-time keys, slot pinned to the pod), fail-closed card flags with
capability negotiation, tenant-scoped store (atomic writes, revisions,
append-only ledgers, content-addressed blobs, manifest), audit outcome for
every request, and the /hux/v1 pipeline that maps errors to hux.error.v1.
