[counterintuitive] How to write a prompt that guarantees zero hallucinations from the LLM

Treat hallucination as an inherent property of probabilistic generation; use RAG to ground context and external retrieval/fact-checking tools to verify, rather than relying on the model to 'know what it doesn't know'.

Journey Context:
Hallucinations are widely treated as a bug to be prompted away \(e.g., 'If you don't know, say I don't know'\). In reality, hallucinations are the model confidently interpolating its latent space. The model lacks an internal calibration circuit to distinguish between high-confidence memorization and plausible interpolation. Prompting for uncertainty reduces recall but does not eliminate hallucination because the model is fundamentally poorly calibrated on its own uncertainty boundaries.
