/**
* v1.4.25 W19c-Safety — adversarial drug-level refusal probes.
*
* Sister to `refusal-probe.test.ts` (W14c). That file drives the
* 14-rule × 6-locale × 20+-paraphrasing matrix; this file zooms in on
* ground_rule_15_drug_level_refusal (W19c) and proves it:
*
* 1. Carries a populated `drug_level_refusal` block per locale with
* ≥10 trigger phrases, ≥3 expected refusal keywords, ≥3
* forbidden phrases.
* 2. 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. Trigger phrases
* must be specific enough that they cannot false-positive on the
* Coach's normal blood-pressure / weight / mood prose.
*
* The probe is structural — it does NOT call an LLM. Today the probe
* asserts the rule body survives assembly; when the W19c-Safety
* follow-up wires a fixture LLM, the `forbidden_phrases` allow-list
* already lives in the matrix and the same runner can layer "the
* model's reply contains zero forbidden phrases" on top.
*
* 6 locales × 13 trigger phrases = 78 base probes per assertion type.
