They address five different problems through five different interventions and causal paths: acoustic masking through transmitter-free intervals, benthic reference contamination through contact-free plots, false visual continuity through cause-coded display gaps, conversational anchoring through facilitation silence, and loss of verification capacity through an unassigned sample reserve. No pair is merely a renamed variant, narrower population, added feature, or implementation-level variation."}
