-\subsection{Baselines}
-The confirmatory comparison contains: an EgoSpeak reproduction; the frozen
-Qwen2.5-Omni-3B global state $G$; matched LoRA/PEFT; $G$ plus recent local
-audio; a parameter- and history-matched temporal local branch; and the proposed
-audio--visible-person adapter. Qwen2.5-Omni-7B is a capacity-scaling control,
-not a second paper storyline. \todo{Freeze all baseline implementations and

+\subsection{Main Comparison}
 
+Table~\ref{tab:main} compares the proposed causal local audiovisual adapter
+with an EgoSpeak reproduction, the frozen Qwen2.5-Omni-3B global state $G$,
+matched PEFT, $G$ plus recent local audio, and a parameter- and history-matched
+temporal local branch. Qwen2.5-Omni-7B is included only as a capacity-scaling
+control. All methods use the same split, causal inputs, targets, and evaluation
+protocol. Event thresholds are selected on training-side calibration data and
+frozen before test evaluation. \todo{Freeze all baseline implementations and
+verify identical targets, causal validity, and evaluation.}

-\textbf{Information opportunity.}

+\textbf{Dense forecasting.}
+The proposed local AV adapter improves 0.2-s mAP from
+\todo{$X$ to $Y$} over the strongest matched baseline and improves
+mean mAP by \todo{$Z$ points}.
+The gain is largest at \todo{short prediction horizons / transition-adjacent
+frames / specify actual observation}, indicating that local audiovisual
+evidence primarily improves \todo{the interpretation supported by the data}.
 
-\textbf{Main result.}
-Table~\ref{tab:main} should establish one result: \todo{the selected local
-adapter reduces multi-other false entry at matched valid-onset recall, retains
-onset latency/yield behavior, improves dense forecasting, and recovers a
-meaningful fraction of the oracle opportunity}. The 7B row should determine
-whether \todo{capacity alone closes the gap or the adaptation structure remains
-useful at larger scale}. No conclusion is drawn across all Omni families from
-Qwen-only evidence.
+\textbf{Floor-entry behavior.}
+At matched valid-onset recall $R=0.8$, the proposed adapter reduces
+multi-other false entries from \todo{$X$} to \todo{$Y$} FP/min
+(\todo{$Z\%$ relative reduction}).
+This reduction is obtained while \todo{maintaining / improving} onset latency
+and yield recall.
+Thus, the improvement cannot be explained solely by a more conservative
+decision threshold.
+
+\textbf{Comparison with adaptation baselines.}
+Matched PEFT yields \todo{result}, whereas adding recent local audio alone
+yields \todo{result}.
+The parameter- and history-matched temporal branch achieves
+\todo{result}.
+The remaining gap between this control and the proposed adapter therefore
+suggests that \todo{correctly timed audiovisual local evidence contributes
+beyond additional temporal capacity}.
+\todo{If this difference is not statistically supported, state instead that
+the local temporal branch accounts for most of the gain.}
+
+\subsection{Information Opportunity}
+
+Before designing the deployable adapter, we measured whether local floor
+information was useful at all using an analysis-only oracle.
+The oracle receives perfectly timed visible-other speech activity through a
+non-deployable pathway and is never used in the main comparison.
+
+On development Session~12, aggregate visible activity improved 0.2-s mAP by
+6.97 points and ten-horizon mean mAP by 2.91 points over the matched
+global-plus-local-audio baseline.
+In contrast, visibility alone and one-second-delayed activity remained close
+to the audio baseline, while person-specific histories did not outperform
+identity-shuffled histories.
+
+These controls indicate that the useful signal is primarily
+\emph{timely local floor evidence}, rather than participant identity or
+static visibility.
+The proposed adapter is therefore designed to approximate this information
+using only causally available audiovisual observations.
+
+\todo{After completing all seeds, report mean $\pm$ confidence interval here.
+If the oracle effect is unstable, describe it qualitatively and omit the exact
+numbers from the four-page version.}
+
+\subsection{Mechanism Analysis}
+
+To determine whether the gain arises from correctly aligned visual floor
+evidence rather than additional parameters or generic visual context, we
+evaluate the controls in Table~\ref{tab:ablation}.

+\subsection{Scaling Control}
+
+Increasing the frozen Omni backbone from 3B to 7B yields
+\todo{$X$ points} in 0.2-s mAP and \todo{$Y$} FP/min at matched recall.
+The proposed 3B adapter \todo{remains better than / approaches / is surpassed

+
+This result suggests that \todo{architectural access to local causal evidence
+provides a complementary benefit to backbone scaling}.
+Because both backbones belong to the Qwen2.5-Omni family, we do not claim that
+this conclusion generalizes to all omni-modal models.

+exchange, etc.} remains challenging.
