Reasoning order
Section titled “Reasoning order”RULE → FACT → CONTEXT → ANSWER:先确认 applicable rule/authority,再读取 operational fact,再补充 context,最后给出带 provenance/conflict disclosure 的回答。
Bilingual retrieval
Section titled “Bilingual retrieval”FDN-COST-001 zh-CN 与 FDN-COST-001 en 是同一对象的 representations。Search 可按用户语言返回结果;若语义冲突,必须报告而不是由 similarity 决定 authority。
Safety boundary
Section titled “Safety boundary”Knowledge access ≠ execution authority。 Retrieval 不授予 approval、financial posting、migration、deletion、production mutation 或 rule-modification authority。
