/**
 * @module simple-ibgib is stubbed for now.
 *
 * This came from a chat with Gemini regarding hiding some complexity contained
 * in the primitive transforms: mut8, rel8 and fork. This particular approach
 * Gemini came up with as an optimistic write-based manager to be used when
 * dealing with POJOs (or POTOs I suppose in TypeScript).
 *
 * I am leaving this here to be picked up at a later time, as this moves towards
 * a more ORM approach, and our near-term use case is more of a simplification
 * for consumption in our own blank-gib app. We mainly need to fix diverging
 * timelines and this was a conflict resolver approach, while I was working
 * towards a lock-based approach.
