Guard rails are the processor's, not this runner's: no China nexus -> out_of_scope; missing global or domestic input -> abstain; and with no coupling baseline wired (v1), a topic without gazetteer corroboration abstains rather than scores — a topic China never covered being quiet at home is disinterest, not suppression. An abstention is published as an abstention, never as a zero. DDTI terms carry china_nexus by provenance: they are drawn from the censor's own deletion stream, so this runner sets the nexus flag at source and the processor's per-term gazetteer gate is deliberately bypassed for them (it still guards any non-DDTI deployment). A blind round (nothing scored) records null blackout counts in both the latest reading and the history, never zeros",
