[research] LLM states a fact early in a long generation, then contradicts it later in the same output

Implement a post-generation consistency check pass \(e.g., using a separate LLM call or NLI model\) to verify that claims in the conclusion match claims in the introduction, or break long generations into smaller, state-managed steps.

Journey Context:
Autoregressive generation only conditions on past tokens; as the context window fills, attention dilutes and the model 'forgets' what it said earlier, leading to drift. This is especially common in long-form article generation or multi-step reasoning. Simply increasing context size doesn't fix the attention dilution. The robust solution is an external consistency verifier or stateful generation where the agent tracks its own asserted facts.
