 ## Positioning
 
-The paper is deliberately framed as a causal global--local **audit**, because
-that is the strongest complete story supported by archived evidence:
+The paper now starts from the egocentric conversational agent's when-to-speak
+problem, positions it against 27 cited works in turn-taking, first-person
+audio-visual conversation, active-speaker modeling, and streaming Omni
+interaction, then studies two cutoff-aligned interfaces:
+
+- **short-window encoder evidence (SWE)**: direct recent audio and optional
+  person-crop visual encoder features alongside the frozen Omni readout;
+- **partial-tail refresh (PTR)**: query only the observed prefix of the current
+  two-second block at each 200-ms cutoff, reusing completed payloads.
+
+The evidence remains a causal global--local **audit**, not a claim that all
+Omni models lack local perception or that PTR's independent gain is proven:
 
 - global Omni context and recent audio are complementary across all horizons;
 - most measured benefit is dense forecasting and wearer-offset anticipation;
