StandardAudit is a standalone Rails gem for database-backed audit logging. On Rails 8.1+ it subscribes to Rails.event; on Rails 8.0 it falls back to ActiveSupport::Notifications. Generic, flexible, and works with any Rails application.

StandardLedger marks ActiveRecord models as immutable, append-only journal entries with idempotency-by-unique-index, provides a StandardLedger.post helper that returns a Result (optionally the host's own Result type), a Projection base class for host-side projectors, and StandardLedger.refresh! for host-owned PostgreSQL materialized views (including concurrently: :auto).

StandardPagination wraps pagy with one controller concern, one metadata shape, safe page-size handling, out-of-range error handling, deterministic tie-broken ordering, and an MCP list helper shared across Rails apps.
