WHY IT NEEDS A POLICY

Why apply_voice_rules needs a policy

This tool modifies draft content by applying voice rules in a deterministic, reversible manner. It transforms a draft but does not delete, execute arbitrary operations, move money, or access external systems — it is a pure text-processing function. The modification is reversible (the original draft could be regenerated or recovered).

From the tool's definition Tool description states it 'applies every rule to the draft in source order, returns the rewritten draft + an edit log.' The verb 'rewritten' and 'returns the rewritten draft' indicates modification of data (the draft content).
