[counterintuitive] Tell the LLM to be logically consistent across a long output and it will comply

Enforce consistency through system design: structured outputs with schemas, validation steps, caching previous decisions, and external state management. Don't rely on instructions alone to maintain global consistency.

Journey Context:
Autoregressive models generate one token at a time and cannot revise previous tokens. When you instruct a model to 'be consistent,' you're asking it to maintain a global property through purely local decisions without a backtracking mechanism. The model has no way to check whether token N is consistent with token N-500. It can attempt to be consistent with its recent context, but over long outputs, drift is inevitable. This is the same reason humans use scratchpads and editors rather than writing perfect first drafts. The model needs the same: external state tracking and revision mechanisms, not just instructions to 'be consistent.'
