Don't Rewrite Your Framework
summary
Shows concrete Rails features and how they replace hand‑rolled hacks: use context validations to run different rules per step, map address fields to a Value Object via composite to get Address#== working, wire after_add/after_remove to keep a cart total in sync (example works), process records with find_in_batches (default batch size 1,000) and split 200 ids across two workers, prevent races with lock_version optimistic locking or FOR UPDATE inside a transaction, and use Rails 7.1 normalize for standardized attributes.
