FIELD NOTE / X
Two models can widen the options.

Two models can widen the options.

Two models can widen the options. A late event could be delivery, ordering or stale read state. A durable experiment record prevents the next loop repeating them. #EricFieldNotes

I do use model loops when a design is uncertain. They are good at proposing rival explanations and overlooked paths. The mistake is treating the most persuasive answer as the verdict before any measurement can disprove it.
Suppose an approval appears twice. One model blames duplicate delivery; another blames out-of-order updates. Both could be wrong if the UI reads a stale projection. Asking them to debate longer does not reveal which system state actually changed.
For delivery, compare event IDs and idempotency records. For ordering, reorder a disposable event stream. For stale reads, inspect source state and projection lag. Record a predicted trace for each, then run the cheapest safe probe that separates them.
Store the predicted signatures, observed traces, rejected explanations and remaining uncertainty. Let models help design the next probe, but let system readback settle the choice. Do this because a loop of eloquent answers is not an engineering process until it risks being wrong.
