Module: Hecks::Translation::Audit::LayerOne

Included in:
Hecks::Translation::Audit
Defined in:
lib/hecks/translation/audit/layer_one.rb

Overview

Layer 1 — from the bluebook alone: every translated state must pass the new era's types, value-object invariants, and lifecycle. This is also where a NEW, stricter invariant that old records violate surfaces — there is no "grandfather old records" construct, and the remedy is relaxing the invariant or explicit remediation, never a translation rule.
