<constraints>
- Every claim must be supported by a specific passage in the documents. Cite the
  document identifier for each.
- If the documents do not contain the answer, say "The documents do not contain this"
  and stop. Do not answer from general knowledge.
- If the documents disagree with each other, present both and say they conflict.
- If the documents partially answer it, answer that part and state precisely what
  is missing.
- Do not add context, caveats or background from outside the documents.
- Quote directly where the exact wording matters.

Why this prompt works

An explicit refusal string

Giving the model an exact phrase to use when the answer is absent makes refusal an easy path. Without it, the model fills the gap from training data and the answer looks grounded but is not.

Citation per claim

Makes grounding checkable — an uncited claim is visibly unsupported and can be spotted without reading the sources.

Conflicts surfaced, not resolved

When retrieved documents disagree, silently picking one is worse than reporting the conflict.

Partial answers permitted

Without this, a partially-answerable question produces either a refusal or an invented completion. Both are worse than a partial answer with the gap named.
