+an attention-pooled context: a query formed from $\vect g_n$ and valid

+token), rather than averaging it beforehand. The resulting context and

+cross-entropy over causal-valid source--horizon pairs. The principal SWE
+configuration freezes all feature encoders and the Thinker: this is
+frozen-backbone adaptation, not task-level end-to-end training.

+layers are read. The primary comparison trains only the layer-combination
+projection, local-fusion modules, and 30-logit prediction head on cached
+frozen features. Parameter-adaptation controls instead attach low-rank
+adapters to Thinker attention projections, either across the configured
+Thinker or restricted to its upper layers; the prediction head may be
+updated jointly or held fixed to isolate representation changes. These
+controls require the same causal media, source cutoffs, supervision,
+initialization, and model-selection protocol as the frozen-head condition.
+Archived LoRA runs, including an upper-eight-layer setting, are
+exploratory and not a matched layer-scope ablation. Last-four-layer

-\subsection{Visible-Activity Information Audit}
+\subsection{Short-Window Feature Extraction}
 
-To distinguish missing information from ineffective learned vision, we build
-analysis-only features from transcript-derived \emph{past} activity.  At each
-cutoff, visible non-wearer participants receive two seconds of binary history
-sampled on the same 5-Hz grid.  The preparation fails if its aggregate
-activity disagrees with the released target.  We compare: (i) visibility with
-activity zeroed, (ii) per-person histories, (iii) identities shuffled while
-preserving active-person counts at every lag, (iv) histories delayed by one
-second, and (v) one OR-pooled aggregate-visible history.  These conditions
-never expose future activity, but their speech labels make them privileged
-diagnostics, not deployable features or upper bounds.
+We define every local observation by its prediction cutoff, before applying
+any encoder-specific preprocessing. The default audio branch encodes the
+mixed waveform in $[t_n-1\,\mathrm{s},t_n)$ with the frozen Qwen2.5-Omni
+audio encoder and averages valid output tokens. A wav2vec~2.0 convolutional
+audio representation, as used by EgoSpeak \cite{kim2025egospeak}, is an
+encoder-choice control; it must use the same one-second input interval and
+forecasting head before differences can be attributed to the encoder. It is
+not the source of the reported $\G+\A$ result.
+
+For vision, a single-frame variant uses the latest frame strictly before
+$t_n$; the pooled person-crop variant averages frozen Qwen vision tokens
+within provided boxes, across visible people, and over valid 2-FPS frames
+in the preceding second. These pooled features summarize appearance but
+discard person identity and explicit motion. Boxes are dataset-provided,
+not predictions from an evaluated online detector. Two no-box full-frame
+alternatives retain the post-merger spatial-token grid: F2 lets the
+global--audio query attend to the latest causal frame; F3 first encodes up
+to two observations at each matching grid location in chronological order
+with a shared GRU, then applies the same query to the resulting grid. F3
+links image coordinates, not people or tracks. Its difference from F2
+confounds additional history and temporal capacity, so it cannot alone
+establish a motion or speaker-grounding mechanism. Empty or unavailable
+local evidence is indicated by the validity masks, never filled with a
+future observation.
+
+As a distinct, privileged short-window feature, we also derive visible
+non-wearer speech activity from transcript annotations \emph{before} each
+cutoff. Each visible participant contributes a two-second binary history
+on the 5-Hz grid. We test visibility-only, per-person, identity-shuffled,
+one-second-delayed, and OR-pooled aggregate histories to ask which timely
+activity information a learned visual branch would need to recover.
+Although strictly past-only, these annotations are not available from raw
+media at inference; this is an information audit, not a deployable feature
+or a performance upper bound.
