[ EXECUTIVE TEARDOWN // TL;DR ]
The near-fatal trap: JSON.stringify-ing React Flow nodes persists the view — 90%+ renderer state the client can reconstruct for free.
A lossless, schema-aware Serialization Adapter maps UI objects to compact domain structs, cutting payloads 94% round-trip.
The win compounds: instant saves, a stable domain schema for versioning and execution, and UI redesigns that never break old data.
Audit your own product: sample a persisted payload and highlight what the client could derive — the ratio is usually shocking.
