The four-layer boundary
What should never be delegated to free-form text generation?
- Deterministic code owns balances, spreads, slippage, flows, denominators, timestamps, and formatting.
- Statistical models can estimate distributions or calibrated probabilities only under a documented validation method.
- Retrieval supplies approved evidence objects. A language model may explain them but cannot silently fill a missing field.
Take one Bathymark reading and label each field as deterministic, statistical, retrieved, or generated explanation.
