BLUM Finance 4B Outcome-Aware Challenger

This repository contains a non-production challenger trained locally from the immutable BLUM snapshot snapshot-3e00c6ee6fdd.

It teaches BLUM to critique a historical thesis after a mature outcome is observed. The original decision remains point-in-time; outcome evidence is introduced only in a later conversation turn.

This is not enough to promote the model. The latest temporal test contains 53 confirmed outcomes and zero contradicted outcomes, so a model that always emits confirmed can look successful. Decision-contract preservation also requires a larger independent evaluation.

Promotion status: BLOCKED. The adapter is published for reproducibility and future champion/challenger evaluation only. It does not establish trading alpha, forecast accuracy or profitability and must not authorize trades.

See evaluation/evaluation.json for the complete blocker record.
