Eve-Finance F5/reasoner

Five cooperating models. One routing classifier, one reasoner, and three frontier slots composed best-fit for the request in front of them. The composition is the same on every vertical; what differs is the corpus, the specialists and the controls around it.

Pinned where it has to replay. A valuation must be reproducible in front of a credit committee or a trustee years later, so a mark is struck against pinned engine versions and recorded with them. A mark that cannot be reproduced is refused rather than stored — under a retrieval architecture the engine is the valuation function, and a floating version silently re-prices the book.

Routed where it is read once. A conversation, a recall, a summary — read by a person, never replayed as evidence of a price. Those take a routed path. The split is on what the answer is FOR, not on who asked.

The engine never names itself. The only engine string that appears on any customer surface is Eve-Finance F5/reasoner. A lane that names the model underneath it fails closed rather than being redacted mid-sentence — a half-redacted sentence in an audit artifact is worse than a declared missing one.
