- Guard _triliteral_root() rotor to Hebrew-script roots only; Greek/other
scripts now use the root: rotor alone (0.17) — no spurious uppercase
Unicode blade collision from the romanization fallback path
- test_structured_morphology_improves_same_root_hebrew_resonance: replace
tag_only baseline (now empty since legacy tags stripped) with no_morphology
baseline (domain+pos+lemma+surface only), which is the honest comparison
for what structured morphology contributes post-migration
