Overview

Shared flat-payload writer for has_many associations whose rows are STI-typed and carry preferences/calculator metadata. Used by Promotion (rules, actions) and PriceList (rules).

The wire shape is [{ type:, id?, preferences: {...}, calculator?: {...}, *_ids?: [...] }] and the reconciliation is: existing rows update by id, new rows build via find_by_api_type, missing rows destroy. Falls through to AR's standard writer when assigned model instances (Rails internals do this on association swap).

New-record parents defer the work into an @pending_<assoc> ivar so child rows can FK to a persisted parent — the consumer model is responsible for flushing those in an after_save.
