+The streaming rows answer two different questions. First, full causal-prefix
+recomputation and streaming cache reuse at the same 5-Hz Qwen cutoffs test
+whether cache/chunk semantics change the representation; equivalent outputs
+make this an efficiency control rather than a distinct predictive method.
+Second, the matched Qwen 5-Hz and 1-Hz cached rows test whether an advantage is
+explained by more frequent causal state refresh rather than the proposed local
+evidence route. For native 1-Hz streams, the state emitted at the end of each
+one-second chunk is never backfilled into earlier 200-ms rows; source gaps and
+session boundaries reset all modality and language-model caches. MiniCPM-o is
+a secondary cross-family diagnostic under the same 1-Hz schedule, not a
+same-frequency architecture ranking. Its 5-Hz cached-branch row is omitted if
+cached/full-prefix equivalence, cutoff invariance, or reset audits fail.
