The authority re-rank always ranked binding law above guidance, so a guideline
could never be Top-1 even when the user explicitly asked "what does the EDPB /
ENISA say?". Add a tightly-bounded override: only when the query carries an
explicit guidance signal (EDPB / DSK / ENISA / BSI / Leitlinie / Guideline /
Orientierungshilfe / Auslegung / empfiehlt / Empfehlung / sagt / laut) AND the
guideline is semantically competitive with the best binding hit (>= best_binding
- 0.05) does supervisory_guidance get a +0.25 boost that lets it overtake the
binding norm. Obligation questions (no signal) are unchanged: binding stays #1.
Gate verified on dev:
- "Ab wann DSB-Pflicht?" -> Art. 37 DSGVO (binding) Top-1
- "Was empfiehlt der EDPB zum DSB?" -> EDPB guidance Top-1
- "Was sagt die ENISA zu Security Updates?" -> ENISA guidance Top-1
- "Welche Anforderungen an Security Updates?" -> Art. 13 CRA (binding) Top-1
