Module: Hecks::Ports::Persistence::Plugins::Era

Defined in:
lib/hecks/ports/persistence/plugins/era.rb

Overview

ADR 0033 — requiring THIS FILE is installing the plugin. Nothing in Hecks core requires it; an app that binds PostgresEra, or wants schema-translation support at all, requires it explicitly — the same shape every adapter-specific spec fixture already uses to load one particular .adapter file rather than all of them.

Class Method Details

.contribute_boot_gates(registry, gates) ⇒ Object

Runtime::Loader.run_boot_gates! asks every loaded persistence plugin to contribute here, generically — it never mentions EraCheck or "era" by name. Two gates, both :pre_verify:

:era_compute_rules — unconditional, whenever this plugin is loaded at all. A compute/rekey rule requires Postgres whatever adapter is actually bound (ADR 0031's own reasoning, unchanged) — this is the rich, adapter-aware version of that check; Runtime::Loader's own structural backstop (plain Bluebook::Translation data, no plugin-specific class) only ever fires when NO persistence plugin is loaded at all.

:era_check — conditional, exactly ADR 0031's own gate, unchanged: registered only when this registry has an aggregate actually bound to a lineage-capable adapter.
