The TDDDG (ex-TTDSG) pilot revealed §25 TDDDG (terminal-equipment / cookie consent)
ranked #3 on a cookie query — the subsidiarity rule demoted it as DE law subsidiary
to the DSGVO, but TDDDG is lex specialis (ePrivacy) for cookies.
Topic-based fix (NOT blanket TDDDG > DSGVO):
- cookie/ePrivacy topic (cookie/endeinrichtung/endgeraet/tracking -> §25 TDDDG) so it is
co-primary (topic-matched -> topicGain, no subsidiarity demote).
- TDDDG/TTDSG added to the data_protection domain (chunkDomain recognition).
- cookie-specific keywords (NOT bare 'Einwilligung') so a general consent question still
resolves to Art. 7 DSGVO.
Acceptance on the DSGVO+BDSG+TDDDG build: cookie -> §25 TDDDG top-1; Rechtsgrundlage -> DSGVO;
DSB -> Art.37+§38 BDSG (not TDDDG); degraded=0, must_not=0. go build/vet/test green; 2 new table tests.
