[counterintuitive] Model contradicts itself across turns or fails to maintain consistent state throughout a multi-step coding task

Maintain all state externally in structured data \(JSON, database, variables\). Have the model read state before acting and write state after acting. Never rely on the model to 'remember' and stay consistent with its own prior outputs without explicit re-presentation of those outputs in context.

Journey Context:
Developers expect that if a model commits to a design decision in step 1 \(e.g., 'we'll use Redis for caching'\), it will remain consistent through step 10. When it doesn't, they assume it's a memory or attention problem solvable with longer context. The deeper issue: LLMs don't have persistent beliefs or mutable internal state. Each generation is a fresh prediction conditioned on the context window — the model doesn't 'decide' something and then 'remember' it. It generates the most likely next token given the context. If the context makes a different continuation more probable \(due to competing patterns, ambiguity, or stochastic sampling\), the model will contradict itself without any awareness of doing so. This is not fixable by prompting because there is no 'self' with consistent commitments — there is only a text continuation engine. For coding agents, any state that must remain consistent \(variable names, architectural decisions, API contracts, data schemas\) must be externalized and explicitly provided back to the model at each step.
