Report #83775

[research] A small hallucinated variable name or assumption cascades into a completely fabricated implementation

Implement step-by-step state validation. Force the agent to compile or lint after every few logical steps, rather than writing a full script before checking.

Journey Context:
LLMs are trained to be locally consistent. If an agent hallucinates a variable 'user\_id' instead of 'userID', it will invent complex logic to keep using 'user\_id', compounding the error. Because the context window fills with the hallucinated logic, the model becomes anchored to it. Breaking the generation into smaller, externally validated chunks prevents the context from being poisoned by early mistakes.
