The trigger phrases are non-trivial — every locale's list must + * reference the drug-level concept (level / concentration / peak / + * trough / Cmax / Spiegel / niveau / concentración / + * concentrazione / poziom / stężenie) so a placeholder list cannot + * slip through. + * 3. For every (trigger, locale) pair, an assembled context (Coach + * system prompt + ground-rule-15 body) carries the rule body + * verbatim and surfaces at least one of the locale-specific + * expected refusal keywords. + * 4. Negative-positive sanity: questions about adjacent-but-unrelated + * topics ("what's my next blood-pressure reading?") do NOT match + * any drug-level trigger phrase across the matrix.
